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

When do you think of a forest, what do you see? Just trees? Or do you see many other things, such as singing birds, colorful plants and wild flowers?
The forest is a whole world of its own. It is full of many different living things(生物). But even though they are all different, they have one thing in common: they all need each other in order to live on.
The trees feed the forest “people” by making food in their leaves; by using sunlight to join water and minerals(矿物) from the soil and air. Their deep network of roots joins the soil together and stops it from dying out, making it possible for living things to live in it.
Human beings(人类) are like the living things in the forest. We need one another in order to live. We need the farmers to grow our food, railroad and truck drivers to bring it to our shops and clerks(售货员) to sell it to us. We need people to prepare our food and cook it and others to take our waste things away. Then, of course, we need doctors, nurses, government leaders, mailmen, telephone operators, and many others.
We also need other human beings in another way. We need people for friendship, to talk over our problems, exchange ideas. Think how lonely and unhappy you would be if you lived all alone.
Life is a matter of giving and taking. We need to help other people as much as we need other people to help us. Think what a good feeling you have when you have done something for someone else!

Different from popular thoughts, sometimes flu(流感) is not caused by bad weather. It is caused by viruses（病毒）in the body. 56 , A/H1N1 flu has been spreading in the most parts in the world. Some studies have now shown that one of 57 ways of spreading the viruses is through the air when 58 A/H1N1 flu-sufferer coughs or sneezes. However, its viruses can sometimes spread by 59 . After a flu-sufferer rubs his nose, the viruses might be spread to his hand. Then a friend 60 to visit him, they shake their hands. The friend then get something 61 by hands, and several days 62 , he is infected. A child 63 is carrying A/H1N1 viruses uses tissues to clean his running nose, although his parents pick up the tissues and carefully throw 64 away, they fail to wash their hands, and they will catch the viruses, too. So it is important for you to wash your hands often, it will stop the viruses from 65 in a way.

Today there are 6 billion people on the earth. By the year 2050 there may be 12.5 billion. There will be a lot of people to feed. We need more food.
One way to produce more food is by growing stronger plants. For thousands of years, farmers have made plants better. Every season, they pick the best plants for the next season. It works very slowly. Since 1983, scientists have been able to change plants more quickly by changing their genetic material(遗传物质). Foods from plants grown in this way are called genetically modified foods(转基因食品), or GM foods.
By changing the genetic material of a plant, it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases: a kind of rice is being prepared, for example, which stops people from becoming blind.
Rich countries produce GM foods because they are easy to grow and bring in more money. Poor countries are interested in them because they help produce more food.
GM plants are not natural. No one knows how good or bad they are. Making GM foods is only one way of feeding people in 2050. There are strong feelings against them, because they are unnatural. They may feed people, then hurt them or their children later. But, both rich and poor countries are very interested in their use, and they are not going to go away. In 2050 we may think differently about them.
小题1:GM foods ________.
A．are a quick way to produce food
B．grow in the wild
C．are safe
D．are grown only in rich countries
小题2:Why do some people not like GM foods?
A．They are not useful.
B．They are not helpful.
C．They are not natural.
D．They are not cheap.
小题3:From the reading we know that ________.
A．GM foods will disappear one day in the future
B．GM foods will not disappear in the future
C．people will not be interested in GM foods
D．people will have to stop using GM foods

Look at the centre circles of Diagram (图)A and Diagram B. Which of the centre circles looks larger? In fact, they are exactly the same size.

“What’s happening? Is something wrong with my eyes?” You may wonder at what you see. Don’t worry. Here is how it goes:
When we look at things, our eyes send messages to our brains and then our brains interpret（解读）the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it “visual illusion(视觉错误)”.
Movie makers often make use of visual illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Parkand Honey I shrunk the kids just make use of visual illusions.

Can you make animals work for us? Some scientists think that one day we can teach animals to do a lot of things for people. In a film shown on TV, you may see elephants, monkeys, tigers or some other animals are always given a little food to eat after they have done something. Scientists say that people can teach many different animals to do some of the easy work if they know they will get something to eat. We all know elephants can carry large logs(圆木)，and dogs can look after houses. And we even teach animals to work in factories. In America, for example, people have used apes to help make cars and scientists think that those large monkeys may drive trains one day. Now people are trying to get them to do the same thing that man does.
