When the research on the effect of electric fields on E．coli was begun in 1962, it was essential that a biologist–specifically, a microbiologist–contributed to the project．She does not want her name used because she did not become a scientific researcher for fame, but rather for the challenge of putting pieces of a scientific puzzle together．
As a girl, she was inspired by the work of great scientists: she read the story of the cure of malaria in the Panama Canal; she also read a biography of Madame Curie．These accounts inspired her to pursue a career in scientific research．After high school, she worked for the Michigan Department of Health, where she did research in biology and microbiology．There, her colleagues saw her talent and encouraged her to pursue science as a career．She went on to earn a bachelor’s degree from Michigan State University in 1948 in medical technology．
When she began working at Michigan State in the early 1960s,
she was balancing the demands of scientific research with the needs
of her family．At that time both of her children were in school．She
would work in the lab in the morning while they were at school,
go home to see them at lunch, return to the lab for the afternoon, go
home for dinner, and return to the lab in the evening, if necessary．
At that time, there were fewer women scientists working than
there are today, but she encountered several in her career．At the
Michigan Department of Health, many of her colleagues were women and, consequently, she did not feel isolated because of her gender–nor did she feel that she was treated differently because she was a woman．      
While working at Michigan State, she also felt that she was treated with respect by her peers．Her colleagues, among them doctors and Ph．D．chemists, all treated her as an equal．On the whole, she believes that there is not a great deal of difference between men and women in science．
56．Why does the woman scientist refuse to let out her name?
A．Because she is a shy lady．
B．Because she doesn’t mind her fame．    
C．Because she never takes pride in her research．
D．Because she never works for her fame．
57．What is the noble lady scientist really interested in?
A．The life stories of other women scientists．
B．Biology and microbiology．
C．The secret of the success of the other scientists．
D．The difference between men and women scientists．
58．Who helped and encouraged her to carry on her scientific research?
A．Her family and friends．                             B．Madame Curie．
C．Her colleagues and other scientists．              D．Some of the officials．
59．What is the whole passage mainly about?
A．The life story of a famous woman scientist with great success．
B．A brief introduction about an unknown great woman scientist．
C．The new development of a special woman scientist．
D．The secret of an infamous woman scientist．

Scientists say the warming of the Earth’s atmosphere has begun to affect plant and animal life a
round the world. Scientists from the University of Hanover in Germany reported their findings in Nature. They say global warming is affecting endangered  species, sea life, and the change in seasonal activities of organisms. Global warming is caused by carbon dioxide and other heat-trapping gases in the atmosphere.
Studies show that the Earth’s climate has warmed by about six tenths of one degree Celsius during the past one hundred years. Most of the increase has taken place in the last thirty years. German scientists have studied different animal and plant population around the world during the past thirty years. They say some species will disappear because they cannot move to new areas when their home climate gets too warm.
The scientists say one of the biggest signs of climate change has been the worldwide decrease in coral reefs. Rising temperatures in the world’s warm ocean waters have caused coral to lose color and die. In the coldest areas of the world, winter freezing periods are now happening later and ending earlier. Researchers say these changes are having severe effects on animals such as penguins, seals, and polar bears.
Changes in temperature and wetness in the air can also affect the reproduction (繁殖) of some reptiles(爬行動物) and amphibians(兩棲動物). For example, the sex of baby turtles is linked to the average temperature in July. Scientists say even small temperature increases can threaten the production of male turtles.
In Europe, scientists say warmer temperatures are affecting the spring and autumn seasons. This is affecting the growth of plants and delaying the flight of birds from one place to another.
Scientists are concerned about invasions of warm weather species into traditionally colder areas. Rising temperature has been linked with the spread of diseases in areas such as Asia, East Africa, and Latin America.
44. The best title for this passage would be __________.
A. Effects of Global Warming   B. Temperature and Animals
C. Global Warming and the Environment D. A Study on the Environment
45. According to the passage, global warming is affecting all of the following, EXCEPT _________.
A. endangered species            B. sea life
C. activities of organisms        D. the color of turtles
46. We can learn from this passage that _________.
A. the speed of the earth’s warming is faster now than 50 years ago
B. more animal species will soon come into being
C. animals will refuse to move to warm places in the future
D. cold areas have gained more heat than warm places
47. If the temperature in the Arctic Ocean keeps going up, which of the following will be most likely to happen?
A. More and more people will come to live near the Arctic Ocean.
B. More crops will be grown near the Arctic Ocean.
C. Animals from warm areas will come to live in the Arctic Ocean.
D. There will be more and more fish in the Arctic Ocean.

While scientists are worried that humans are causing higher temperatures on the Earth, a Maryland man, Ace, thinks we can save the world by spraying（噴射）huge amounts of water into the air.
Ace told the McClatchy News Service that at least 1,000 places should be chosen to spray water. The water would be sprayed between 20 and 200 feet into the air. Thousands of tons of seawater would be sprayed for years at a time.
The 1,000 sites would be picked after more studies. They would be mostly in the Northern Hemisphere(北半球). Ace says he would avoid tropical（熱帶的）areas of the globe. He says water turns to rain too quickly in these areas for his plan to work.
The water would be changed into vapor. That process requires heat. The water vapor would rise above the Earth. The water vapor would form clouds. The clouds would help in several ways. They would cool the Earth by reflecting sunlight. They would later turn into rains. The rains would provide another way of cooling the Earth.
Ace’s plan has gotten some support from a limited scientific study. Kenneth Caldeira is a climate scientist. He works at the Carnegie Institution’s Department of Global Ecology at Stanford University in California. Caldeira tested some of the Ace’s figures on a computer program. The computer model is used by top scientists to study global climate change. The model showed that the plan might work.
“More tests are planned in 2009. Ideas like Ace’s should be considered carefully and with an open mind,” Calderira said. “Every brilliant（卓越的）invention in the history of technology looked a little bit mad when first put forward.”
65.What’s the purpose of Ace’s plan?
A. To reduce air pollution.                  
B. To make summer cooler.
C. To offer dry areas more rain.                  
D. To solve the problem of global warming. 
66.According to Ace’s plan,___________.
A. planes would be used to spray water.       
B. it would be best to spray water on rainy days.
C. seawater would be sprayed high into the sky
D.1,000 sites in the Southern Hemisphere would be chosen.
67.Why wouldn’t Ace spray water in tropical areas?
A. Water is changed into vapor too quickly.      
B. Water turns to rain too quickly.
C. It is hard for vapor to form clouds.           
D. It is bad for local plants to have too much rain.
68. It seems that Caldeira ____________.
A. takes Ace’s plan seriously                 
B. thinks Ace’s idea too crazy
C. doesn’t believe the computer’s result        
D. agrees to carry out Ace’s plan right away

Most sharks are dangerous. The largest kind of sharks—the whale shark—has small teeth and is quite harmless to people. However, blue sharks, tiger sharks, white sharks and hammerheads are enemies of man.
Man-eaters are always a danger to swimmers in shark waters. Sometimes, though, men have used strange methods when they’re suddenly faced with a shark.
During world War Ⅱ, soldiers and sailors whose boats or planes were destroyed drifted(漂流) helplessly on the ocean in small rafts(筏子). While waiting to be saved, the men had to struggle to stay alive and were often attacked by sharks. In some cases, they had few weapons to protect themselves with. They found that just splashing(濺水) water seemed to help keep the sharks away.
One sailor was swimming for his life in the Atlantic Ocean after his boat had been blown up. He saw a shark swimming towards him. He hit the shark with his bare fist, and that drove it off.
Once, in Australia, a fisherman was fishing after sunset. He hooked a big fish and drew it towards the shore. His line broke when the fish was only a few yards from the shore. The fisherman waded(涉水) into the water to try to catch it with his hands. In the dim light, it looked like the kind of fish that could be dealt with without danger.
He put his arms around the fish and wrestled with it. Dragging it to the beach turned out to be harder than he had expected, but at last he pulled it in. When he turned a light on it, he was amazed. He had caught a shark. It was small for a shark, but it was the man-eating type and was about as long as a tall man.In a word, the best way to deal with sharks is to keep far away from them.
60. The shark that is least dangerous to man is the ________.
A. white shark      B. whale shark   C. tiger shark     D. hammerhead shark
61. This story tells you that sharks are usually ________.
A. friendly         B. small         C. afraid of people     D. dangerous
62. After the Australian fisherman found he had caught a shark, he was _________.
A. surprised      B. frightened      C. unhappy      D. angry
63. This story tells you that the best way to handle sharks is to ________.
A. hit them with your fist                 B. keep far away from them
C. splash water                         D. wrestle with them
64. The passage mainly tells us something  ________.
A. about fishing sharks                  B. about sharks
C. how to eat  sharks                   D. that sharks are man’s enemies

Ocean Acidification: 'Evil Twin' Threatens World's Oceans
The rise in human emissions of carbon dioxide is driving dangerous changes in the chemistry and ecosystems of the world's oceans, international marine（海洋的）scientists have warned. "Ocean conditions are already more extreme than those experienced by marine organisms and ecosystems for millions of years," says the latest issue of the journal Trends in Ecology and Evolution. "This emphasizes the urgent need to adopt policies that markedly reduce CO2 emissions."
Ocean acidification, which the researchers call the 'evil twin of global warming', is caused when the CO2 emitted by human activity, mainly burning fossil fuels, dissolves into the oceans. It is happening independently of, but in combination with, global warming. Evidence gathered by scientists over the last few years suggests that ocean acidification could represent an equal -- or perhaps even greater threat -- to the biology of our planet than global warming. More than 30% of the CO2 released from burning fossil fuels, cement production, deforestation and other human activities goes straight into the oceans, turning them gradually more acidic.
"The resulting acidification will impact many forms of sea life, especially organisms whose shells or skeletons are made from calcium carbonate（碳化鈣）, like corals and shellfish. It may interfere with the reproduction of plankton species which are a vital part of the food web on which fish and all other sea life depend," he adds.
The scientists say there is now persuasive evidence that mass extinctions in past Earth history, like the "Great Dying" of 251 million years ago and another wipeout 55 million years ago, were accompanied by ocean acidification, which may have delivered the deathblow to many species that were unable to cope with it. "These past periods can serve as great lessons of what we can expect in the future, if we continue to push the acidity the ocean even further" said lead author, Dr. Carles Pelejero, from ICREA and the Marine Science Institute of CSIC in Barcelona, Spain. "Given the impacts we see in the fossil record, there is no question about the need to immediately reduce the rate at which we are emitting carbon dioxide in the atmosphere," he said further.
"Today, the surface waters of the oceans have already acidified by an average of 0.1 pH units from pre-industrial levels, and we are seeing signs of its impact even in the deep oceans," said co-author Dr. Eva Calvo, from the Marine Science Institute of CSIC in Spain. "Future acidification depends on how much CO2 humans emit from here on -- but by the year 2100 various projections indicate that the oceans will have acidified by a further 0.3 to 0.4 pH units, which is more than many organisms like corals can stand," Prof. Hoegh-Guldberg says.
"This will create conditions not seen on Earth for at least 40 million years."
"These changes are taking place at rates as much as 100 times faster than they ever have over the last tens of millions of years" Prof. Hoegh-Guldberg says. Besides directly impacting on the fishing industry and its contribution to the human food supply at a time when global food demand is doubling, a major die-off in the oceans would affect birds and many land species and change the biology of Earth as a whole profoundly, Prof. Hoegh-Guldberg adds.

Garbage is unwanted or unusable materials. As long as there are people on the planet，there will be garbage Garbage is directly linked to human development,both technologically and socially.The composition of waste has yared Over time and location，with industrlal development.Examples of this include plastics．Some garbage has economical value and can be recycled once correctly recovered.
For most of us, "out of sight,out of mind": throw it away and it`s gone.But imagine what really happens to all the rubbish the world throws away.Now suddenly，the government is worried about mountains of garbage piling up with no place to put them all．
China`s increasing prosperity and urbanlsm create tons of garbage since the 1980s，causing tons of trouble.The amount of paper,plastic and other garbage has increased more than three times in two decades to about 300 million tons a year．As busy families are shifting from fresh to packaged foods,more garbage is expected．
There are also a huge number of people who go through the garbage to find anything that can be of value and recycled!The recycling is carried out every day when peope come to your house to take away your newspapers and cardboard，plastic and metal items.Every neighborhood has a garbage point.Take a train trip and there are recycling yards all along the tracks in every city. Food waste is collected by farmers to feed animals.
Even though we make an effort to recycle our solid waste，the amount of waste keeps increasing each year．Our biggest problem is where to put the solid waste and how to keep it from polluting our environment.If the solid waste is disposed incorrectly,it can pollute earth`s surface an underground water supplies.Currently,Our municipal waste goes to landfills or garbage dumps.
The waste must be treated to keep rats，flies and other anlmas from building their homes in the landfills.The treatrment also prevents the growth of bacteria that carry diseases．
The government knows such garbage disposal（處理）will always draw complaints．What they need to do is invest more money into bullding and maintaining better evelironment.

Scientists in the United States have developed a method that may help to predict earthquakes earlier. They say it could give people who live in deadly earthquake areas enough warning to leave before an earthquake occurs.
Currently, the most modern systems for predicting earthquakes find them only a short time before the event. Like most strong earthquakes, Wenchuan earthquake in 2008 and Haiti earthquake in 2010 were not identified early enough for people to flee the area, killing hundreds and thousands of people.
But scientists who study earthquakes are reporting that new technology could measure very small changes in the Earth’s surface.
Scientists performed experiments along California’s San Andreas Fault, an area famous for its earthquakes. Highly sensitive electrical devices are placed about one kilometer below ground in two different places. The devices were able to measure even small changes in air pressure on the Earth’s surface. The scientists say such changes are caused when rocks pushed together, forcing air out of small cracks in the rock.
Two earthquakes hit the area in late 2005. The first took place on Dec.25. A smaller earthquake struck five days later. The scientists noted changes in the earth’s surface about ten hours before the first quake struck. That quake measured three in intensity(強度). They then found similar changes taking place two hours before the other quake struck five days later.
If additional tests confirm the changes are linked to earthquakes, the scientists believe their equipment could be used for early warning systems. A system that provides a warning signal ten hours before a major earthquake could help move people from the area and save lives.
The scientists now hope they can find earthquakes with even greater intensity by placing their equipment deeper in the ground.
71. What’s the best title for the passage?
A.A new way to help predict earthquakes.

D.fewer people will be killed in an earthquake
73.According to the passage, the devices can predict the earthquake by______
reaching the center of the earthquake
detecting the temperature changes in the earth’s crust
measuring changes in air pressure on the Earth’s surface
recording sound waves under the ground
74.We can infer from the passage that ______.
the equipment is perfect enough to be used in practice
it’s unknown if greater earthquake can be predicted by the equipment

Scientists in Canada say big ocean fish have almost disappeared from the world since the start of industrial fishing in the 1950s. The scientists found the populations of large fish like tuna(金槍魚), swordfish and cod（鱈魚） have dropped by ninety percent in the past fifty years.
The study took ten years. The researchers gathered records from fishing businesses and governments around the world. The magazine Nature published the findings.
The scientists say the common method called long line fishing is especially damaging to populations of large fish. This method involves many fishing lines connected to one boat. These wires can be nearly one hundred kilometers long. They hold thousands of sharp metal hooks to catch fish.
Long line fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one hundred hooks. But long line fishing boats now might only catch one fish per hundred hooks.
The scientists say industrial fishing can destroy groups of fish much faster than in the past. The study suggests that whole populations can disappear almost completely from new fishing areas within ten to fifteen years.
Ransom Myers and Boris Worm of Dalhousie University in Nova Scotia led the study with the University of Kiel in Germany. Worm says the destruction could lead to a complete reorganization of ocean life systems. Meyers says the decreased numbers of large fish are not the only worry. He says even populations that are able to reproduce do not get the chance to live long enough to grow as big as their ancestors. He says not only are there fewer big fish, but also they are smaller than those of the past.
American government scientists say even with the best efforts to protect fish populations, decreases are to be expected.

The weather predictions for Asia in 2050 read like a script from a doomsday(世界末日，最后審判日)movie. Many climatologists and green groups fear they will come true unless there is a concerted global effort to rein in greenhouse gas emissions.  
In the decades to come, Asia -- home to more than half the world's 6.3 billion people -- will lurch（突然傾斜）from one climate extreme to another, with impoverished farmers battling droughts, floods, disease, food shortages and rising sea levels.
"It's not a pretty picture," said Steve Sawyer, climate policy adviser with Greenpeace in Amsterdam. Global warming and changes to weather patterns are already occurring and there is enough excess carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come.
Already, changes are being felt in Asia but worse are likely to come, Sawyer and top climate bodies say, and could lead to mass migration and widespread humanitarian crises. (人道主義危機)
According to predictions, glaciers will melt faster, some Pacific and Indian Ocean islands will have to evacuate or build sea defenses, storms will become more intense and insect and water-borne diseases will move into new areas as the world warms.
All this comes on top of rising populations and spiraling demand for food, water and other resources. Experts say environmental degradation(環(huán)境惡化) such as deforestation(森林砍伐) and pollution will likely magnify the impacts of climate change. In what could be a foretaste of the future, Japan was hit by a record 10 typhoons and tropical storms this year, while two-thirds of Bangladesh, parts of Nepal and large areas of northeastern India were flooded, affecting 50 million people, destroying livelihoods and making tens of thousands ill. The year before, a winter cold snap(寒流，寒潮，驟冷)and a summer heat wave killed more than 2,000 people in India. 
59. Which of the following has the similar meaning to rein in?
A. slow down, control        B. increase, enhance    C. bring in                      D. take in
60. According to the passage, which one is true?
A. The changes of weather will never lead to mass migration and widespread humanitarian crises.
B. The number of the population in Asia is the largest of all continents.
C. Global warming and changes will happen in the near future if we don’t take any actions.
D. Deforestation and pollution will not magnify the impacts of climate change.
61. The reason why glaciers will melt faster is that                
A. there is more and more carbon dioxide and other greenhouse gases in the atmosphere.
B. there is less carbon dioxide and other greenhouse gases in the atmosphere
C. the weather changed suddenly.   
D. The reason is still unknown.
62. This passage is mainly about              .
A. what kind of weather we like best.
B. the whole world will not be suitable for us to live in.
C. how to improve our environment.
D. the weather predictions for Asia in the future and the reasons.

A low-carbon lifestyle means cutting carbon dioxide emissions and living a life characterized by low-energy use, low consumption and low spending. This way of living is being accepted by a growing number of average people in China.
Before low-carbon became a popular word here, some environmentally conscious people known as "Lohas" had already devoted themselves to living green, low-carbon lifestyles. Lohas is for "lifestyles of health and sustainability." It was first introduced in 1998 by American sociologist Paul Ray and later became a popular lifestyle in western countries. After this concept was introduced into China a few years ago, Lohas was translated into a proper Chinese word "lehuo," meaning happy living.
Zhang Tao from a joint venture in Beijing is a Lohas supporter and follower. He and some others set up a Lohas club two years ago. They often get together to share their experiences about living green lifestyles or to volunteer for environmental protection activities.
Zhang says Lohas is both a lifestyle and an attitude towards life rather than just a fashion or slogan.
"A Lohas lifestyle means a natural and healthy life with low costs. We don't drive cars, and we try our best to save water and electricity. Some people misunderstand us as being too stingy. But in fact, most of us are well-paid. We don't do it to save money, but for the sake of the environment. Living a rich life doesn't mean you can waste resources. We hope what we do can help save energy and reduce the pressures on earth. I know our personal strength is too small, but the changes will be great if everyone can make a little contribution."
64. A low-carbon lifestyle has the following features except_______.
A. low energy     B. low wages     C. low consumption   D. low spending
65. A Lohas is most likely to_______.
A. drive a car to work every day   B. save money to live a better life
C. turn off the tap when not using   D. leave the light on day and night
66. What does the word “stingy” mean in the last paragraph?
A. generous               B. mean              C. rich                D. willing
67. In Zhangtao’s opinion, _________.
A. Lohas is just a fashion or form     B. one shouldn’t get well paid
C. one should live a happy life             D. environment protection depends on everyone
