The world's largest solar thermal plant(太陽(yáng)熱能發(fā)電站)is set to begin producing power in the United States by the end of the year. Wind and energy from the sun are generally considered clean, unlike energy from coal-burning power stations. However, environmentalists now worry that too much solar power development could harm the local environment.
A California company — BrightSource Energy is building a huge solar power plant in the Mojave desert, about 60 kilometers southwest of Las Vegas, Nevada. The plant is known as the Ivanpah Solar Electric Generating System. Joe Desmond works for the company. "This is actually one of the highest concentrations of sunlight in the world, out here in Ivanpah." explained Desmond. BrightSource Energy will deploy 170,000 specially de­signed mirrors to direct solar energy towards boilers on top of three power towers. The steam produced in the boilers will drive turbine (渦輪) to make electricity. Joe Desmond says the steam can reach temperatures of more than 260 degrees Celsius. "We can store the sun's thermal energy in the form of molten salt, so we can produce electricity even when the sun goes down. There is a lot of interest in concentrating solar power around the globe in environmnents where you have lots of sun, such as China, South Africa, the Mid­dle East, North Africa, explained Desmond.
Environmentalists generally support the idea of solar power, however, many are concerned about the effect of power plants on sensitive environment. Lisa Belenky is a lawyer with the Center for Biological Diversity, a private group. She says environmentalists are specifically worried about the effect of the Ivanpah Solar Project on the sensitive plant and animal life in that part of Mojave desert. "Even though the desert seems big, when you start cutting it up, it can really affect how the species and the animals and the plants are able to survive in the long run,"said Lisa Belenky. BrightSource Energy has already spent more than $ 50 million to move endangered desert tortoises away from the power plant. but Lisa Belenky says this is not the answer. "We should be reusing areas that have a1ready been disturbed, like old mining sites, for example...either on homes, on businesses, parking lots." said Belenky.
There have also been reports of birds dying at the Ivanpah Plant and others like it.
Some birds die after colliding with solar equipment which the animals mistake for water. Other birds were killed or suffered burns after flying through the intense heat at the solar thermal plant. As solar projects increase, environmentalists and developers are considering what to do to reduce bird death.
小題1:Why is the Ivanpah Solar Electric Generating System being built in the desert?
A.Because the temperature is extremely high in the desert.
B.Because there is no life in the desert.
C.Because there is much salt in the desert.
D.Because sunlight is highly focused in the desert.
小題2:Why can the plant make electricity at night?
A.Because the sun's thermal energy can be stored in the form of steam.
B.Because the sun's thermal energy can be stored in the form of molten salt.
C.Because the sun'ss thermal energy can be stored through mirrors
D.Because the sun's thermal energy can be stored in the boilers.
小題3:According to Lisa Belenky, in order to reduce the effect,_____.
A. we should move all the plants and animals away from the solar plant
B. we should guide the bird not to hit the solar plant
C we should build the solar plant in disturbed areas
D. we should build the solar plant in the desert
小題4:The author’s attitude towards the solar projects is _____.
A.supportiveB.critical C.indifferentD.cautious

When 18th-century scientists first came across Australia’s platypus(鴨嘴獸), they thought it was a trick. It is not surprising that the platypus made people confused. This funny-looking animal has feet and is a kind of warm-blooded mammal.
While other mammals usually keep their blood at around 37 degrees, the platypus has a lower body temperature of 32 degrees. As to its appearance, the platypus’mouth is not really like ducks’at all; its mouth actually looks a bit soft. The platypus closes its eyes when swimming. It uses its mouth to pick up outside information made by the creatures underwater.
Strangest of all, the platypus is a mammal that can lay eggs. And there is only one other kind of mammal that can lay eggs, the echidna (針鼴鼠) of Australia. Both the platy-pus and the echidna lay soft-shelled eggs, and both feed their young with their own milk that comes out of their skin. These animals also walk in a way that is similar to crocodiles(鱷魚), with legs on the sides of their bodies rather than under them.
Though pretty, in a special way, the platypus is actually one of the few mammals that are poisonous. A male platypus has knife-like bones on its back legs which have enough poison to kill a dog.
The platypus has the honor of being one of the oldest mammals in the world. Until the early 20th century, it was hunted for its fur, but the situation has changed. Although the platypus is easily affected by pollution, it is not under any immediate threat.
小題1: What can we learn about the platypus according to the text?
A.It has a lower body temperature than other mammals.
B.It only closes its eyes when underwater.
C.It’s the only poisonous mammal in the world.
D.It feeds its young on wild animal meat.
小題2:Which of the following is NOT used as a comparison with the platypus in the text?
A.The crocodile.B.The echidna.C.The duck.D.The dog.
小題3:The following characteristics of the platypus have been described in the text EXCEPT ________.
A.its natural enemyB.its appearance
C.its walking poseD.its daily diet
小題4:We can infer from the last paragraph that the platypus _______.
A.is hunted for its meatB.is in danger of extinction
C.is endangered by air pollutionD.is well-protected now
小題5:Which of the following would be the best title for this text?
A.Platypus, a Trick?
B.Platypus, the Only Warm-Blooded Mammal
C.The Characteristics of Platypus
D.The Strange Mammal —Platypus。

Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world? It is an increasingly urgent question, given the recent mining accidents in Sago, W. Va and Huntington, Utah. A small group of engineers and robotics experts look forward to a day in the not-too-distant future when robots and other technology do most of the dangerous mining work. 
Robotic technology, in particular, holds much promise, McAteer says, especially when it comes to mapping mines and rescuing trapped miners --- the special operations of the mining industry.
One of the first mining robots was developed five years ago at Carnegie Mellon University’s Robotics Institute. It was called Groundhog. It used lasers(激光器) to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business. 
The latest design is called Cave Crawler. It’s a bit smaller than Groundhog,and even more advanced. It can take photos and videos and has more sensors that can detect the presence of dangerous gases. Incredibly,the robot has a real sense of logic. If it comes across an obstacle it gets momentarily confused. It has to think about what to do and where to go next. Sometimes it throws a fit just like a real person. 
The greatest problem, though, is cost. The money of the earliest research project was provided by the government, but that money had dried up, and it’s not clear where future money will come from. Partly for that reason, and partly because of advances in safety, mining is not nearly as dangerous as it was in the past. Since 1990, fatalities(致命性) have declined by 67% and injuries by 51% , according to the National Mining Association.
Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry. The robots do the most boring and dangerous jobs,but won’t get rid of the need for human workers.
小題1:The latest robot is more advanced than Groundhog, mainly because ____.
A.it can map abandoned mines
B.it can see in the dark tunnels
C.it’s smaller than Groundhog
D.it has a real sense of logic
小題2:The underlined phrase “throws a fit” in paragraph 4 probably means“______”
A.gets angryB.gets sick
C.becomes hungryD.becomes cheerful
小題3:We can infer from the last paragraph that _____ .
A.robots in mines will serve much in the automotive industry
B.there will be no need for human workers in mines
C.the mine robots will have a very bright future
D.robots in mines only do some simple jobs now
小題4:We can infer from the text that ______.
A.the mining robots do most of the mining work at present
B.groundhog can discover the presence of dangerous gases
C.experts are trying to make robots help miners with dangerous work
D.robots cannot do dangerous work in dark areas
小題5:What can be the best title for the text?
A.Mining Accidents in America
B.Robots in Mines
C.Cave crawler, the Latest Robot
D.The Future of Robots

Teachers say the digital age has had a good influence - and a not-so-good influence - on this generation of American teenagers.More than 2,000 teachers took an online survey.Three-quarters of the teachers said the Internet and digital search tools have had a "mostly positive" effect on their students' research habits and skills.But 64 percent said the technologies "do more to distract(使 - - - ---分心) students than to help them academically." And 87 percent agreed that these technologies are creating an "easily distracted generation with short attention spans."
The Pew Internet Project did the survey with the National Writing Project.Judy Buchanan is the vice director of the National Writing Project and a co-author of the report.Ms.Buchanan says digital research tools are helping students learn more and faster."Teachers really favor these tools because they are ways to make some of the learning exciting and engaging.Young people favor these tools.The goal is to really help them become creators of meaningful content, and not just sort of consumers."
But one problem the survey found is that many students lack digital literacy.They trust too muck of the information they find on the Internet.Judy says these students haven't developed the skills to determine the quality of online information."It's something that really has to be taught and paid attention to.Because in a world in which things happen quickly, you do need to step back, reflect and analyze the information you have."
Another problem is blamed on something that might not seem like a problem at all: being able to quickly find information online.Teachers say the result is a reduction in the desire and ability of their students to work hard to find answers.They say students are overly dependent on search engines and do not make enough use of printed books or research libraries.
Many teachers are also concerned that the Internet makes it easy for students to copy work done by others instead of using their own abilities.
小題1:The text mainly tells us____.
A.a(chǎn)ll the students use digital tools
B.the Internet is playing a key role
C.teachers encourage using digital tools
D.digital tools bring about benefits and problems
小題2:Which of the following best shows the structure of the text?

小題3:The underlined sentence in the third paragraph probably means
A.students do not have the right digital tools
B.students do not always have access to the Internet
C.students haven't the ability to adjust themselves
D.students can't judge online information properly
小題4:Some students don't tend to work hard because
A.they can get answers on the Internet quickly
B.printed books and libraries around aren't enough
C.the Internet can't make students concentrate
D.they can copy each others' work without being punished

Attempts to understand the relationship between social behavior and health have their origin in history. Dubos (1969) suggested that primitive(原始的)humans were closer to the animals because they, too, relied upon their instincts to stay healthy. Yet some primitive humans recognized a cause and effect relationship between doing certain things and alleviating(減輕)symptoms of a disease or improving the condition of a wound. Since there was so much that primitive humans did not understand about the functioning of the body, magic became an integral component of the beliefs about the causes and cures of health disorders. So it is not surprising that early humans thought that illness was caused by evil spirits. Primitive medicines made from vegetables or animals were invariably used in combination with some form of ritual (禮儀) to drive harmful spirits away from a diseased body.
One of the earliest attempts in the Western world to formulate principles of health care based upon rational thought and rejection of supernatural phenomena is found in the work of the Greek physician Hippocrates. Little is known of Hippocrates who lived around 400 B.C., not even whether he actually authored the collection of books that bears his name. Nevertheless, the writings attributed to him have provided a number of principles underlying modern medical practice. One of his most famous contributions, the Hippocratic Oath, is the foundation of contemporary medical ethics (道德). Among other things, it requires a physician to swear that he or she will help the sick, keep oneself from intentional wrong-doing or harm, and keep secret all matters to keep the doctor-patient relationship.
Hippocrates also argued that medical knowledge should be derived(源自于)from an understanding of the natural sciences and the logic of cause and effect relationships. In this classic thesis, On Airs, Waters, and Places, Hippocrates pointed out that human-being is influenced by the totality of environmental factors: living habits or lifestyle, climate, geography of the land, and the quality of air and food. Interesting enough, concerns about our health and the quality of air, water, and places are still very much written in the twentieth century.
小題1:The topic of the first paragraph is summarized in ________.
A.the first sentence of the paragraph
B.the second sentence of the paragraph
C.the third sentence of the paragraph
D.the last sentence of the paragraph
小題2:Why did primitive humans rely on magic in their beliefs about the causes and cures of diseases?
A.Because magic was an inseparable part of their life.
B.Because they had little knowledge about the functioning of the body.
C.Because the diseases were caused by the evil spirits.
D.Because magic must be used in going through the rituals to drive out the evil spirits.
小題3:Considering Hippocrates’ background, we can see from the second paragraph that ________.
A.he was the forefather of modern medicine
B.experts are sure that the books bearing his name were not written by him
C.he had a rational mind aided by supernatural instincts
D.experts do not know much about him except when and where he lived
小題4:All of the following are included in the Hippocratic Oath EXCEPT ________.
A.helping patients
B.keeping oneself from harming patients
C.keeping secret all matters to maintain a good relationship with the patients
D.obeying rules for modern medicine practice
小題5:Which of the following best expressed the main idea of the last paragraph?

Air pollution is one of the hottest topics at present because poor air quality is an important factor in both the incidence and cause of respiratory(呼吸道) diseases.
Zhong Nanshan, a deputy to the NPC and a member of the CAE, said recently when the concentration of PM2.5 rises by 10 micrograms per cubic meter, hospitalization may rise by as much as 3.1 percent. Meanwhile, when the concentration of PM2.5 rises from 25 mgs per cubic meter to 200, the average daily death rate may rise to 11 percent.
Zhi Xiuyi, a leading expert in lung cancer treatment and also vice-president of the CATS, said medical authorities used to focus on tobacco control as a primary means of preventing lung cancer. "But in fact, air pollution is no less harmful than smoking and our research team released a report earlier this year showing that the cancer rate in Beijing is closely related to industrialization," he said.
The report, conducted by the Beijing Institute of Cancer Research, shows that the number of cancer patients in China has increased markedly during the past ten years. Chaoyang District, the city's main area of industrialization, has the highest incidence of cancer, almost double that of Yanqing, an area on the outskirts of the city. About four out of 1000 Chaoyang residents have some form of the disease, with lung cancer at the top of the list.
"The risk of having cancer largely depends on the length of exposure and the concentration of noxious gases(有毒氣體的濃度)," said Zhi. In response to the doubt whether seven years' exposure to poor air quality will almost result in cancer, Zhi said the time scale was taken from research overseas that suggested the rate of incidence generally peaked in the seventh year of exposure to a heavily polluted environment.
小題1: What is the passage mainly about?
A.Medical researches on environment.
B.The disadvantages in big cities.
C.The only reason for the lung cancer.
D.Poor air quality contributing to lung cancer.
小題2:What can you conclude from the 3rd paragraph?
A.Compared with smoking, air pollution is more harmful.
B.Air pollution is as harmful as smoking.
C.It is very important to prevent people from smoking.
D.People realize the importance of keeping healthy.
小題3:If there were 3,000,000 people in Chaoyang District, how many would have respiratory diseases?
A.16000B.12000C.8000D.7500
小題4:What can you infer from the passage?
A.Industrialization has its weakness as well as strengths.
B.The average death rate rises with different ages and places.
C.The air in Beijing is much more polluted than that in the other cities.
D.The more heavily-polluted air you breathe in, the sooner you’ll have cancer.

October 15th is the Global Handwashing Day. Activities are planned in more than 20 countries to get millions of people in the developing world to wash their hands with soap. For example, donors(捐贈(zèng)者) will give 150,000 bars of soap to schools in Ethiopia.
Experts say people around the world wash their hands every day, but very few use soap at so-called important moments. These include after using the toilet, after cleaning a baby and before touching food.
Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the United Nations Children’s Fund, American government agencies, the World Bank and soap makers Unlever and Procter and Gamble. The organizers say all soaps are equally effective at removing disease-causing germ(細(xì)菌). They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub(揉搓) it into all areas, including under the fingernails(指甲). Rub for at least twenty seconds. Then rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air.
The Partnership for Handwashing says soap is important because it increases the time that people spend in washing hands. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell. The Partnership for Handwashing also says washing with soap before eating or after using the toilet could save more lives than any vaccine(疫苗)or medicine. Hand washing could also prevent the spread of other diseases. When people get germs on their hands, they can infect(感染)themselves by touching their eyes, noses or mouths. Then they can infect others.
小題1:What’s the best title for this passage?
A.Say no to washing hands in the wrong way.
B.Find out why washing hands carefully is so important.
C.Hand washing: so important----it gets a day of its own.
D.Want to live a longer life?-wash your hands.
小題2:The word “rinse” in Paragraph 3 probably means ______.
A.to dry your handsB.to wash away the soap
C.to rub your hands carefullyD.to clean your fingers
小題3:The last paragraph mainly tells us ______.
A.how to wash your hands correctly
B.why washing hand with soap is so important
C.the dangers of washing hands without soap
D.when we should especially wash our hands with soap
小題4:In which part of newspaper would you most probably read this passage?

Chinese scientists have found a new way to use cells found in human urine (尿液)that could aid in the treatment of a range of nerve disorders.That is a new technique for reprogramming cells in human urine into nerve progenitor cells  that can grow into multi-functional nerve and brain cells.
The technique is expected to be used in the study and treatment of nerve disorders such as Parkinson's disease, Alzheimer's disease and other nerve disorders.
Pei Duanqing, a professor at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, said his research team has combined an episomal system to deliver reprogramming factors with a chemically defined culture medium to reprogram kidney epithelial(腎表皮) cells in urine into NPCs.
These NPCs, normally only found in the human brain, were later proven to be transgene-free and self-renewing, he said.
"These nerve and brain cells can survive for up to one month when transplanted into the brain of a newborn rat," said Pei. "My team is working hard to understand why our experimental condition allowed the urine cells to become NPCs, because we want to improve the technique and make it more efficient".
Scientists have long searched to treat and study neural disorders by obtaining and transplanting neural stem cells. However, the previous method of getting and using cells from either fetal (胎兒)or adult human tissue remains challenging due to ethical concerns and immune system rejections, he said.
Pei hopes the discovery will be used to generate NPCs from patients with nerve disorders such as Parkinson's disease. "These NPCs from patients may help us discover new drugs for these diseases."
"It is a remarkable advance in the stem cell field. The results and methods obtained from this study will be of great value and significance to the field, " said Fred Gage,a professor with the Salk Institute for Biological Studies.
小題1:What is the passage mainly about?
A.NPCs are beneficial in treating human diseases.
B.Chinese scientists succeeded in making NPCs from human urine.
C.Chinese scientists have found cures for all diseases.
D.A new technique was used to study the use of human urine
小題2:Pei and his tean try their best to work hard in order to      .
A.make more contributions to medical study
B.discover another new technique
C.make the technique more perfect
D.treat more patients suffering from bad diseases
小題3:What is the challenge of making NPCs in the previous method?
A.The ethical comcerns and immune system refusal
B.The difificulties in getting cells from human.
C.The under-developed techniques in medical science.
D.The lack of financial support from the government.
小題4:From the last paragraph we can infer      .
A.the new technique will be developed in science
B.the results and methods will be applied to treating cancers
C.the study will give a major push to the stem cell field
D.the mew technique will bring great profis
