Like distance runners on a measured course, all of us will move through time in a roughly predictable pattern.
In the first stage of our lives, we develop and grow, reaching toward the top of physical vitality (活力,生氣).
After we grow up, however, the body begins a process of gradually wearing out.
A new awareness of physical fitness may help lengthen our years of health and vitality, yet nothing we do will work to stop the unavoidable force of aging.
Most of the changes of aging take place deep inside the body. The lungs become less able to take in oxygen. Powerful muscles gradually lose their strength. The heart loses power and pumps less blood. Bones grow easier to break.
Finally, we meet a stress, a stress that is greater than our physical resistance. Often, it is only a minor accident or chance infection (a disease caused by virus), but this time, it brings life to an end.
In 1932, a classic experiment nearly doubled the lifetime of rats, simply by cutting back the calories in their diet. The reason for the effect was then unknown.
Today, at the University of California at Berkley, Dr. Paul Seagle has also greatly lengthened the normal lifetime of rats. The result was achieved through a special protein limited diet, which had a great effect on the chemistry of the brain. Seagle showed that within the brain, specific chemicals control many of the signals that influence aging. By changing that chemical balance, the clock of aging can be reset.
For the first time, the mystery of why we age is being seriously challenged. Scientists in many fields are now making striking and far-reaching discoveries.
An average lifetime lasts 75 years, yet in each of us lies a potential for a longer life. If we could keep the vitality and resistance to disease that we have at age twenty, we would live for 800 years.

We know the famous ones—the Thomas Edisons and the Alexander Graham Bells —but what about the less famous inventors? What about the people who invented the traffic light and the windshield wiper(雨刮器)？Shouldn’t we know who they are?
Joan Mclean think so. In fact, Mclean, a professor of physics at Mountain University in Range, feels so strongly about this matter that she’s developed a course on the topic. In addition to learning “who” invented “what”, however, Mclean also likes her students to learn the answers to the “why” and ”how” questions. According to Mclean,” When students learn the answers to these questions, they are better prepared to recognize opportunities for inventing and more motivated to give inventing a try.”
So, just what is the story behind the windshield wiper? Well, Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy, but Anderson still wanted to see the sights, so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield, she found herself wondering why there couldn’t be a built-in device for cleaning the window. Still wondering about this when she returned home to Birmingham, Alabama, Anderson started drafting out solutions. One of her ideas, a lever(操作桿)on the inside of a vehicle that would control an arm on the outside, became the first windshield wiper.    
Today we benefit from countless inventions and innovations，It’s hard to imagine driving without Garrett A. Morgan’s traffic light. It’s equally impossible to picture a world without Katherine J. Blodgett’s innovation that makes glass invisible, Can you picture life without clear windows and eyeglasses?
小題1:By mentioning “traffic light” and “windshield wiper”, the author indicates that countless inventions are      .
A．beneficial, because their inventors are famous
B．beneficial, though their inventors are less famous
C．not useful, because their inventors are less famous
D．not useful, though their inventors are famous
小題2:Professor Joan McLean’s course aims to_____.
A．a(chǎn)dd colour and variety to students’ campus life
B．inform students of the windshield wiper’s invention
C．carry out the requirements by Mountain University
D．prepare students to try their own invention
小題3:Tommy Lee’s invention of the unbreakable umbrella was _________.
A．not eventually accepted by the umbrella producer
B．inspired by the story behind the windshield wiper
C．due to his dream of being caught in a rainstorm
D．not related to Professor Joan McLean’s lectures
小題4:Which 0f the following can best serve as the title of this passage?
A  How to Help Students to Sell Their Inventions to Producers?
B  How to Design a Built-in Device for Cleaning the Window?
C  Shouldn’t We Know Who Invented the Windshield Wiper?

Plastics are considered one of the most serious pollutants causing environmental problems. The garbage containing plastics end up in the waterways that eventually flow into the oceans. Accumulation (聚集)of plastic in the ocean endangers marine life and pollutes the water.
Does a plastic continent exist? Yes, a plastic continent does exist and was discovered by Captain Charles Moore a decade ago. The plastic continent is twice the size of Britain and it is the region between the Hawaii Islands and California in the central Pacific Ocean.
One of the causes of the lack of marine life in this region is due to pollution and pollutants are none other than plastics. Captain Charles Moore believes plastic waste started accumulating in the 1950s.
The plastic continent is the man-made continent of floating plastic waste. The fisher men and the sailors have avoided this region for years. The reasons are:
1. There are no fish here because of the lack of nutrients.
2. The zone also lacks the wind that is essential for sailing.
To do research on the ocean pollution, Captain Moore founded Algalita Marine Research Foundation. Other organizations such as Greenpeace supported his cause. The reports of The United Nations Environment Program show that millions of seabirds and marine animals are dying due to the invasion(入侵)of plastics. The waste plastics can be recycled, but in fact they are being thrown into the oceans. The marine animals mistake these for food and eat them. This leads to their death that affects the marine food chain.
To save the oceans from the plastic continent you need to reduce the use of plastics, reuse plastic bags and recycle plastics.
小題1: What can we learn from the first paragraph?
A．A plastic continent does exist in the Pacific Ocean
B．Endangered marine life is well protected.
C．Plastics are one of the main causes of water pollution.
D．Plastics should be forbidden in people’s daily life.
小題2: What is the direct influence of the plastic continent?
A．Local fishermen have to fish in other areas.
B．The water becomes shallow and fish have to move away.
C．The wind is too strong there and it makes sailing more difficult.
D．It makes people realize the importance of protecting the environment.
小題3: It is implied that the work of plastic recycling proves to be ______.
A．effectiveB．expensiveC．a(chǎn) difficult taskD．not good enough
小題4:What can we learn from the passage?
A．Many marine animals are dying due to the broken marine food chain.
B．Captain Moore founded Greenpeace to do research on the ocean pollution.
C．The marine animals have no choice but to eat plastics for lack of food.
D．There are three ways to prevent the oceans from becoming a plastic continent.

Grandparents might be known for spoiling grandchildren, but a new study says they might also be helping the kids improve their social skills and behavior.
Spending time with grandma and grandpa especially appears to help children from single-parent, divorced/separated or stepfamily households, according to the report, published in the February Journal of Family Psychology.
"Grandparents are a positive force for all families but play a significant role in families undergoing difficulties," the study's lead author, Shalhevet Attar-Schwartz, of The Hebrew University of Jerusalem, said in an American Psychological Association news release. "They can reduce the negative influence of parents separating and be a resource for children who are going through these family changes."
In interviewing 11- to 16-year olds from England and Wales, Attar-Schwartz and her team found that the more conversations the youths had with a grandparent, including asking for advice or even money, the better they got along with their peers and the fewer problems they had, such as hyperactivity and disruptive behavior.
"This was found across all three family structures," she said. "But adolescents in single-parent households and stepfamilies benefited the most. The effect of their grandparents' involvement was stronger compared to children from two biological parent families."
The study did not look at children who lived solely with their grandparents, though.
The findings have great implications for people in the United States, the authors said, because American grandparents are increasingly sharing living space with their grandchildren. A 2004 U.S. Census Bureau survey found that more than 5 million households include a grandparent and a grandchild under 18, up 30 percent since 1990, according to background information in the news release.
小題1:It is generally believed that a grandmother __________ .
A．can help a child through hard times

D．from a stepfamily household
小題3:A child who asks his grandmother for money will __________ .
A．have difficulty in getting along with his peers
B．still get along well with his peers
C．be easier to be spoiled than his peers
D．not be popular with peers
小題4: We can learn from the last paragraph that ___________ .
A．there are more families in America undergoing difficulties
B．American parents are much busier than those from other countries
C．American grandparents are much better at bringing up their grandchildren
D．American kids like to share more living space with their grandparents

What do you know about the sea? You may have seen it. Some of us have swum or bathed in it. It looks beautiful on a fine sunny day and it can be very rough when there is a strong wind. What other things do we know about it? Of course, the sea is very large. In the world there is more sea than land. The sea covers three quarters of the earth. The sea is also very deep in some places. It is not deep everywhere, some parts of it are very great. At one spot, near Japan the sea is nearly 11 kilometers deep! Just think of it, the highest mountain in the world is only about 9 kilometers high! If you have swum in the sea, you know that the water is salty. Rivers carry salt from the land into the sea. Some parts of the sea are more salty than other parts. Do you know the Dead Sea in Arabia? It is very salty. Swimmers cannot sink in it! Fish cannot live in the Dead Sea. It is a strange sea. In most parts of the sea, there are a lot of fishes and plants. Some live near the top of the sea. Others live deep down. No sunlight can reach the depth of the sea. So it is completely dark. Strange fishes live there. Some are blind. Some have their own lights. Some have great jaws. With their great jaws, they swallow fish larger than themselves. The sea can be very cold. Deep sea divers know this well. At the top of the water may be warm. Then as the divers go down, the sea becomes colder and colder.
Many scientists are now making a study of animal and plant life in the sea. They hope to find new resources for mankind.

Scientists are closely concerned with the structure of buildings and with the quality of building materials． The World health Organization （WHO) observes that the introduction of air conditioning and energy conservation （保護(hù)) measures have been accompanied by growing problems of indoor air quality． Some pollutants arise from insulation （隔音) products, some from moving cars, and others from modern housing materials． As many Europeans spend up to 90% of their lives in buildings, the health effects of the indoor climate are very important．
　　Some construction materials, including fiberboard, insulation foams and certain glues for man-made wood floor boards, for example, give out organic products such as formaldehyde （甲醛)． Heat and humidity increase the release of formaldehyde and the gas seriously harms the eyes． Paint, lacquer, etc． can also release dangerous gas into indoor air．
　　Construction materials can cause serious damage, especially when they contain asbestos（石棉）． Asbestos is naturally present in rock formations worldwide． It belongs to a family of mineral substances made up of solid, non-combustible（非易燃品） fiber． These properties make asbestos a highly sought-after construction material． As early as 1931, however, public health officers in the United Kingdom revealed the connection between breathing in asbestos dust and such diseases as lung cancer．
　　The land on which a building is sited may also contribute to pollution． Some kinds of granite or similar rocks contain traces of radium． As it breaks down, this naturally radioactive element produces some kind of radioactive gas that goes through tiny cracks in walls, floors and building materials, and makes its way into the building and the rooms． The better the homes are insulated, the more is the dangerous gas in indoor air． The main effect of this dangerous gas on health is to increase the risk of lung cancer．
小題1:What is the main idea of the passage?
A．Some building materials pollute indoor air．
B．Some factors cause indoor air pollution．
C．Asbestos can cause lung cancer．
D．The land on which houses are built contributes to indoor pollution．
小題2:Why are Europeans particularly concerned with building materials?
A．Lots of building materials there are radioactive．
B．They stay home up to 90% of their lives．
C．They have a high rate of lung cancer．
D．They spend most of their time indoors．
小題3:Why is asbestos a sought-after building material?
A．It is a kind of insulation foam．
B．Asbestos will not give out dangerous gas．
C．This material is not easy to catch fire．
D．It is rarely present in rock formations．
小題4:Why should we be careful about the land on which a building is to be sited?
A．To determine whether the land is firm enough for a building to be sited on．
B．To make sure that the land contains no radioactive material．
C．To make certain that the land releases no formaldehyde or other gases．
D．To check whether it contains any combustible materials．
