Scientists in the United States say plant life has increased on Earth in the past twenty years and that in every area of plant growth the increase is the result of weather conditions.
Eight scientists from across the United States did the study. The space agency NASA and the Department of Energy paid for it. The findings were published in the magazine Science.
The researchers spent one and a half years examining weather satellite information. The information was recorded from 1982 to 1999. That period was one of the warmest on record. Researchers found that rainfall generally increased during that time.
The satellites measured the number of leaves on plants and the amount of sunlight taken in. The scientists used that information to estimate what is called net primary production. This is total amount of carbon stored in land plants.
The scientists report a 6% increase in stored carbon since 1982. They say gains were high in equatorial areas, especially around the Amazon River in South America. The area alone had a 1% increase in the net primary production.
Ramakrishna Nemani of the University of Montana in Missoula headed the study. He says reduced cloud cover led to growth in Amazon area. He also says the lack of clouds allowed more sunlight to get through. More sunlight meant increases in photosynthesis(光合作用). That is the process by which plants use energy from sunlight to produce the chemicals they need to grow.
Northern Canada, the north-central United States and northern Europe were second in increased plant growth. Ramakrishna Nemani says a rise in temperature helped plants there.
All together, the report says 25% of areas of plant life on Earth experienced increases. But the scientists also note increase in the number of people on Earth and carbon dioxide levels in the atmosphere. Ranga Myneni of Boston University in Massachusetts, another study scientist says humans use about half the net primary production on Earth. And he notes that the world population grew by 36% during the period of time studied.
1.Which of the following is in charge of the study?
A. The space agency NASA of the US.
B. The Department of Energy of the US.
C. Ramakrishna Nemani in Missoula.
D. Ranga Myneni in Massachusetts.
2.What’s the main cause of the plant growth put forward by the study?
A. Growth in population.
B. Regional features.
C. Seasonal variation.
D. Weather conditions
3. Why do scientists believe that reduced cloud cover has led to the plant growth in the Amazon area?
A. Because plants could take in more sunlight.
B. Because plants could get more rainfall.
C. Because plants could enjoy cooler air.
D. Because plants suffer less from natural disasters.
4. Which of the following descriptions about the years from 1982 to 1999 is TRUE?
A. It was the warmest on record.
B. Rainfall decreased little by little.
C. World population grew by 25%.
D. Stored carbon increased by 6%.

“Clothes Swapping” has become an increasingly popular activity for women in the United States. The women can give away unwanted clothing at a clothes swap event and get something different in return.
Recently about 300 women went to a clothes swap at a high school in Springfield, Virginia. It was the largest crowd ever for the area’s popular clothing-swapping group.
Daphne Steinberg was having a good day. “For anyone who knows Ann Taylor LOFT, Ann Taylor is a really nice women’s designer and I will totally wear this to work. So I love that, I love that I can equip myself for work, have a good time in doing it, not totally bankrupt myself.”
Sandy Van Dusen likes the idea that clothes are finding new homes instead of being thrown away. “Because it helps to keep the Earth green. There’s no point in my opinion in continuing to buy new clothes when we can reuse what’s already here. Give it a new home--- let somebody else love what you used to love and no longer love.”
Kim Pratt organized the clothing-swapping event in Springfield. She also organized a money-raising activity for the high school’s debate team. It is one of several ways that her group gives to charitable causes.Another is by donating all of the “un-swapped” clothing to shelters for victims of domestic violence.
“I started doing this four years ago, and we’ve been doing it for four years, getting bigger and bigger each time we have a swap.”
She used the social media website meetup.com to help publicize the events. The website has helped her group grow from 30 members to 1,300. Mrs.Pratt says most of the members respect the clothing swap rules. But she say competition for desirable fashion can be strong.
“We have to tell people sometimes not to hover over the new people coming in with their clothing. As they put it out, some people tend to grab the stuff right out of their hands and it becomes like a free-for-all. We try to avoid that as much as possible.”
1.At a clothes swap women can______ .
A. make some money by giving away unwanted clothing
B. buy whatever clothing they like
C. have a social gathering and make friends
D. exchange unwanted clothing for something different
2.We can learn from what Daphne Steinberg said that ______.
A. she got some nice clothes at the clothes swap
B. the clothes swap was the largest ever in the area
C. it was the first time she had been to a clothes swap
D. she saved much more money than she had expected
3.What is Paragraph 5 mainly about?
A. How Kim Pratt started the clothing-swapping event.
B. What Kim Pratt did with the un-swapped clothes.
C. How Kim Pratt raised money to help charitable causes.
D. What Kim Pratt did to help people in need.
4.It can be inferred from the last paragraph that ______ .
A. clothes swaps often go out of control in the end

Life expectancy in the United States has been in decline for the first time in decades, and public health officials have identified a series of potential causes, including inaccessible health care, rising drug addiction and rates of mental health disorders, and socio-economic factors. Now, a study led by the Yale School of Medicine has attempted to find out the relative impact of two factors most often linked to life expectancy – race and education – by looking at data about 5,114 black and white participants in four U.S. cities.
The lives and deaths among this group of people – who took part in the study approximately 30 years ago when they were in their early 20s – show that the level of education, and not race, is the best predictor of who will live the longest.
Among the 5,114 people followed in the study, 395 had died. These deaths were occurring in working-age people, often with children, before the age of 60. The rates of death among participants in this group did clearly show racial differences, with approximately 9% of blacks dying at an early age compared to 6% of whites. There were also differences in causes of death by race. For instance, black men were significantly more likely to die of murder and white men from AIDS. The most common causes of death across all groups over time were cardiovascular disease and cancer.
But there were also obvious differences in rates of death by education level. Approximately 13% of participants with a high school degree or less education died compared with only approximately 5% of college graduates.
Strikingly, when looking at race and education at the same time, the researchers found that differences related to race almost disappeared: 13.5% of black subjects and 13.2% of white subjects with a high school degree or less died during the course of the study. By contrast, 5.9% of black subjects and 4.3% of whites with college degrees had died.
Therefore, improving overall quality of education is something tangible that can help reverse (扭转)this troubling trend in reduction of life expectancy among middle-aged adults.
1.What can we learn about the participants in the study?
A.The whites are more aggressive.
B.The whites got higher education.
C.More blacks than whites died young.
D.More whites than blacks died of cancer.
2.Compared with education, the influence of race on death rates is .
A.significant B.unnoticeable
C.growing D.long-lasting
3.What does the underlined word “tangible” probably mean?
A.Realistic. B.Creative.
C.Challenging. D.Temporary.
4.What can be inferred from the research findings?
A.People can get smart through learning.
B.One should not discriminate other races.
C.People don’t enjoy equal rights for education.
D.One can live longer by getting more education.

Scientists from the United States say they have found fish and other creatures living under key waters in Antarctica. They made the announcement after completing three months of research at the Ross Ice Shelf, the world’s largest floating ice sheet.
The researchers hoped to find clues to explain the force of the melting ice and its effect on sea level rise. Reed Scherer and Ross Powell are with Northern Illinois University in DeKalb, Illinois. They just finished up their research on our southernmost continent. Money for the project came from America’s National Science Foundation.
“We chose a study site where, in the first year ,We went into the subglacial (冰川下的)lake and tried to understand the environment in there, both ecologically and in terms of the ice dynamics about how the lake operates ,and how the sediment(沉淀物) underneath the ice sheet operates, as well, because it’s the water and the sediment underneath the ice that controls how fast the ice is flowing into the ocean” says Ross Powell, who led the investigation. The team included scientists ,engineers, machinery and other supplies across the ice from the main U.S. scientific base at Mc Murdo Station to the researcher’s camp .The camp was near a subglacial lake ,where an earlier study took place,
Ross Powell says the latest study may provide evidence that can help predict the effect of climate change on rising sea levels.
“What we have found is that these are very sensitive areas to the stability of how dynamic the ice is and how fast the ice may react to increases of melting both from the ocean and the atmosphere.”
Among the new instruments built for the project was a powerful hot water drill. The researchers used the drill to dig down some 740 meters. They collected water ,sediment and other material from the grounding zone.
Working around the clock before the deep hole refroze, they sent a video camera down to the 400-square-meter undersea area.
Reed Scherer says the video images they saw in the Command Center were a total surprise.
“It’s a very mobile environment. The bottom is changing constantly. And so the things that we saw were all very mobile organisms, things that swim and some things that crawl. And obviously they are getting enough nutrition that they can thrive, Some of the little crustacean-like creatures called amphipods that we saw swam quite quickly and were quite active.”
This is the farthest south that fish have ever been seen. How did the creatures get here? What do they feed on? And what effect will the retreating ice have on them?
Ross Powell says the ice and sediment cores taken from the grounding zone can offer clues.
“We know that the ice is melting there at the moment and so by opening up the cores once they get back, we hope to be able to understand what the ice was doing in the past ,relative to what it is doing now. And because it is melting so fast or seems to be melting fast at the moment, we anticipate that there will he some differences that we’ll see in the history of the ice sheet from the sediment cores, once we open them up .”But Ross Powell says the work raises more questions than it answers.
1.Scientists conducted the three-month research at the Ross Ice Shelf with the intention of .
A. predicting how climate change influences rising sea levels.
B. finding out whether there are life forms existing deep under Antarctic ice.
C. proving the speed of ice flowing into the ocean is controlled by water.
D. discovering an explanation of the effect the melting ice has on sea level rise.
2.What made the researchers surprised when they saw the video images?
A. Researchers saw fish in the farthest south for the first time.
B.A video camera was able to work well under deep icy waters.
C. Sediment cores present differences in the history of the ice sheet.
D. The drill should dig down 740 meters to collect things.
3.From sediment cores taken from the grounding zone, scientists will probably know .
A. what the ice will do in the near future
B. the ice in the grounding zone is melting at the moment
C. some differences rarely exist in the history of the ice sheet
D. something about the creatures under icy water in Antarctic.
4.What can be inferred from the passage?
A. Scientists will conduct a follow-up study on the frozen continent.
B. No creatures once appeared or lived in icy water in Antarctica.
C. America’s National Science Foundation is in complete charge of the research.
D. Researchers have found how the sediment underneath the ice sheet operates.

The world's largest solar thermal plant(太阳热能发电站)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 (涡轮) 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.
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.
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.
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
4.The author’s attitude towards the solar projects is _____.
A. supportive B. critical C. indifferent D. cautious

It seems that electronic devices just keep getting smaller. Scientists in the United States have announced the creation of the first transistor with only two dimensions(二维).
A transistor is a small electronic device that transfers or carries electronic current. Scientists hope these new 2D transistors will be used for building high-resolution(高分辨率)displays that need very little energy.
Two groups of scientists created these 2D transistors. They report that the transistors are only a few atoms thick.
Usually transistors are made with the element silicon(硅). Computer processors, memory chips, TV screens and other electronic devices contain billions of silicon-based transistors. But these very small electrical parts have certain limitations.
Dimitris Ioannou is an electrical engineering professor at George Mason University. He says the traditional transistor has been improved as much as it can be.He adds that researchers have been looking for new materials with special features and they want transistors to be seen through and soft.
“If the layers are very thin, the transistor can become flexible, so it doesn't have to be rigid(坚硬的), like it would be in a silicon chip. So people can think of applications like wearable electronics, television screens and other things,” said Ioannou.
These new transistors can also carry higher current. They also can move the current much faster than traditional transistors. This is important for high-definition screens.
Dimitris Ioannou says the scientific success could prove very useful in the future. "Now, how good and how useful it will be, it's still in the stage of research, but it certainly is an advance," said Ioannou.
1.Which of the following statements about the newly created transistor is TRUE?
A. They are expected to be used in high-resolution displays.
B. The transistors are made with the element silicon.
C. They are rigid, just like traditional transistors.
D. They have already been put into actual use.
2.What does the underlined sentence in Paragraph 5 mean?
A. The traditional transistors have been changed into two-dimensional ones.
B. Many of the traditional transistors have been improved over the years.
C. The traditional transistor has been developed to its fullest.
D. The traditional transistor has been developed quite well.
3.What is Dimitris Ioannou's attitude towards the creation of the new transistors?
A. Negative. B. Neutral.
C. Indifferent. D. Positive.

Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings.
The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
Some scientists have suggested setting a noise limit of one hundred and twenty decibels in the oceans. They have observed that noises at that level can frighten and confuse whales(鲸鱼).
A team of American and Canadian scientists discovered that louder noises can seriously injure some animals.
The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected.
Many researchers whose work depends on ocean sounds are against a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists don't think that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.
1.According to the passage, natural sounds include all of the following EXCEPT________.
A.sounds made by animals themselves
B.ocean drilling
C.underwater earthquakes
D.the breaking of ice fields
2.Which of the following is true of whales?
A.They won't be confused by noises.
B.They are deaf to noises.
C.Their ability to reproduce will be lowered by highlevel noises.
D.Their hearing will be damaged by highlevel noises.
3.According to the passage, what will scientists most probably do in the future?
A.They will work hard to reduce ocean noise pollution.
B.They will protect sea animals from harmful noises.
C.They will try to set a limit of 120 decibels.
D.They will study the effect of ocean noise pollution.
