Electric bicycles which run on battery-operated (电瓶) motors are winning over riders of ordinary bikes 41 their speed, quality and environmental advantage.
They were first 42 on 1980s in China, but the selling was not very good. Today, thanks 43 improvements on battery quality, the electric bikes sell well. There are now more than 100 electric bicycle producers in China and 26 million such bicycles were produced in 2011. Japan is another large 44 of such bicycles in the world with a total production reaching 381,721in 2010.
45 China is one of the largest producers of electric bicycles in the world, the 46 of its producers with mass production (大批量生产) is actually small.
Electric bicycles are still 47 in China. Time is needed for people to become familiar with them and accept them. Each bike’s price of between 2,000 yuan (US $318) and 3,000 yuan (US $477) is still 48 for ordinary citizens (民众). Although such bikes are quick, safe and 49 to operate, their batteries still have shortcomings (不足). They weigh more than 10 kilograms; their service life is 50 two years and they 51 400 yuan each.
There were more than 450 million bikes in China in 2006. If just one percent of all these bikes are replaced by electric 52 , the market will be very large. And 53 the battery is further improved and the price is 54 , many of us will not be able to keep back from 55 the latest electric bikes

How did I become known as a "rubbish picker '?
I never 36 rubbish before. I didn't care where it went or who cleaned it up. But two years ago, I started caring about it deeply. I lived near a forest in Ohio, America. I can walk there 37 three minutes! I used to love going there to play with my dog. One day there was 38 much rubbish there that I became very unhappy. I decided to clean up the forest. I want to 39 happy going there again. I made my first trip to clean the forest that afternoon. I took a big black rubbish bag with me. Ten minutes 40 I started to pick up rubbish, my bag was full! From then on, I go to the forest four times a year 41 rubbish, it makes me feel 42 to do something for the environment. After each trip, I look at all the rubbish that I've found. If 43 of it is recyclable, I keep it. I will keep picking up 44---people stop dropping it. I know I am only doing a small bit 45 the earth, but I think it is important.

More than 50,000,000 people live in the rainforests of the world and most of them do not hurt the forest they live in. They eat the fruits that grow on the forest trees, but they do not cut them down. They kill some animals to eat, but they do not destroy them.
When we cut down the rainforests, we destroy these forest people, too. In 1900, there were 1,000,000 forest people in the Amazon forest. In 1980, there were only 200,000.
The Yanomami live along the rivers of the rainforest in the north of Brazil. They have lived in the rainforest for about 10,000 years and they use more than 2,000 different plants for food and for medicine. But in 1988, someone found gold in their forest, and suddenly 45,000 people came to the forest and began looking for gold. They cut down the forest to make roads. They made more than a hundred airports. The Yanomami people lost land and food. Many died because new diseases came to the forest with the strangers.
The Yanomami people tried to save their forest, because it was their home. But the people who wanted gold were stronger.
Many forest people try to save their forests. Chico Mendes was famous in Brazil because he wanted to keep the forest for his people. “I want the Amazon forest to help all of us-forest people Brazil, and all the Earth,” he said. A few months later, in December 1988, people who wanted to cut down the forest killed Chico Mendes.
In Borneo, people were cutting down the forest of the Penan people to sell the wood. The Penan people tried to save their rainforest. They made blockades across the roads into the forest. In 1987, they closed fifteen roads for eight months. No one cut down any trees during that time.
In Panama, the Kuna people saved their forest. They made a forest park which tourists pay to visit.
The Gavioes people of Brazil use the forest, but they protect it as well. They find and sell the Brazil nuts(坚果) which grow on the forest trees.The number of the people living in the Amazon forest in 1980 was _______ of that in1900.
| A．half | B．one-third | C．two-fifths | D．one-fifth |
The people who _______ have destroyed the rainforest of the Yanomami.
| A．pick fruits and kill animals to eat |
| B．use plants for food and medicine |
| C．have lived there for about ten thousand years |
| D．made the roads and the airports |
Those people built roads and airports in order to ________.
| A．carry away the gold conveniently |
| B．make people there live a better life |
| C．stop spreading the new diseases |
| D．develop the tourism(旅游业) there |
We can infer the underlined word blockades probably means:
| A．包围 | B．障碍 | C．街区 | D．通道 |
From the passage, we learn that _________.
| A．we need wood to build houses, so we have to cut down trees |
| B．the rainforest people have done something to protect their home |
| C．to humans, gold is more important than trees |
| D．we mustn’t cut down any trees or kill any animals |

IQ（intelligence quotient智商）is a score that shows a person’s level of intelligence.
People used to believe that some people are born with a high IQ and some aren’t.
32 , a study by scientist at University College London has challenged（挑战）this idea. According to an article last October on the Journal Nature, scientists are beginning to think that our IQ is not a constant（不变的）score.
The scientists tested 33 healthy young people in 2004 between the ages of 12 and 16. Then they did tests again four years later, when the same people were between 16 and 20.
Scientists found big changes in the IQ scores between 2008 and 2004. Some 33 and some fell 34 as many as 21 points.
To test whether these scores were meaningful, the scientists compared them with results from brain scans（扫描）. They found that the IQ changes matched changes in the structure（结构）of the subjects’ brains. “A change in 20 points is a huge 35 ,” said Professor Cathy Price, who led the research. He said it could mean the difference between an average and a 36 person. The team has not found a clear cause for these changes. However, they say it is 37 that education plays a role in changing IQ.
“Here we have shown that children’s 38 is likely to be still developing, ” says Price. “We have to be careful not to write off 39 performers at an early stage. In fact, their IQ may improve in a few more years. ”

Electronic books have changed the way many people read for 15 . Now online textbooks are changing the way some students learn and some teachers teach.
More than 16 students go to the public schools in Fairfax County, Virginia, outside Washington. Last year, the school system used digital books in fifteen schools. This school year, middle schools and high schools changed 17 printed to electronic textbooks in their social studies classes.
“I mean, it’s just 18 a regular textbook, except it’s got it all online.” says Luke Rosa, a history teacher at Falls Church High School.
Peter Noonan, an assistant superintendent(主管) of schools says, “The world’s changing 19 . And the online textbooks can change right along with the events that 20 .”
“Digital books also cost 21 than printed textbooks,” he says, “Usually it’s between fifty and seventy dollars 22 a textbook for each student, which adds up to about eight million dollars for all of our students in Fairfax County. In fact, we have bought all of the online textbooks for our students for just under six million dollars.”
Social studies teacher Michael Bambara says the e-book he uses in his government class is better than a(an) 23 textbook. It has materials for students 24 different levels of reading skills…

For example, many tree grow thorns (刺)to tell animals 3 near. Most young trees have large and deep green leaves to 4 enough sunlight and turn it into their food and energy. When trees are four years old, they are strong enough to 5 the challenge(挑战)in life. At the age of fifteen, they become young adults and grow more 6 . They will have their own flowers and fruit. After the trees are twenty to twenty-five years old, they are called real adults because they reach their 7 . Adults trees give us oxygen and natural beauty. If we 8 them very well, they will live healthily for many years. As time goes on, trees begin older and older and even 9 .
