Do you have a mobile phone? Do you often send text messages（短信） to your friends or family? If you keep sending text messages over and over again, there may be something wrong with your fingers.  【小题1】 If you don’t, you may get injured one day.
Text messaging or texting is becoming popular. But scientists have found out that texting can give us problems with fingers. Too much texting can make your fingers uncomfortable. When we press small buttons over and over again, we may have a disease called RSI. RSI is short for Repetitive Strain Injury (重复性力损伤).
Harriet Wilson is a doctor. She has many patients with RSI.  【小题2】  If we spend more than 10 to 15 minutes every day, we could have such problems in the future.
Mobile phones are getting smaller and smaller.    【小题3】   Texting with a smaller phone is worse than using a larger phone with bigger buttons.    【小题4】  .
If you use a computer keyboard and play video games for long, you may have the same problem. More and more people can find themselves with RSI.

The Internet, mobile phones and Ipads are part of our lives now. Technology is greatly affecting all ways of our lives, from the ways we work to the ways we play. And it even causes a number of social problems such as cloning humans.
　　We have had lots of technology and it has changed our lives a lot. There is no doubt that humans will continue to use more and more technology. Here are some examples of modern technology that will change our ideas and will affect our lives greatly.
　　Global positioning system (GPS) (全球定位系统)
　　It’s a system that uses radio signals from satellites to show exact(精确地) information. It tells you where the user is on the earth in all weather conditions. It’s made up of three parts: satellites, control equipments (设备) on land and receivers.
　　Space Technology
　　Russian and American scientists have worked together for the international Space Station (ISS) for a long time. They hope the ISS will provide a long-lasting lab. Such a lab will bring humans limitless(无限的) advantages. It’s even hoped that one day space technology will take humans to their new houses in space.
Underwater Robot
Hercules is a kind of underwater robot with some high technology equipments. It will be used to search for ancient ships which were destroyed into the deep sea during their journey long ago.
The world is changing so quickly that it’s hard for us to catch up with all the new inventions because they seem to come out every month. It’s important for us to learn about new technology and the role that it plays in our lives. So we should be willing to accept modern technology, or we will fall behind the times.
【小题1】______ can tell you where the user is on the earth exactly.

It’s a long-awaited day for China. The navy now has its first aircraft carrier(航空母舰), Liaoning.
It’s a unique experience to get to know the life in the carrier. The carrier is just like a small city on the sea. It has all the functions for daily life. There are 4 words to sum up its characters: big, small, much and high. The carrier Liaoning is such a huge one that the total length of the whole corridor（过道）could reach over 20 kilometers. But the living space for the sailors（水手）is quite small. That’s because the carrier is designed for researching purposes, rather than comfortable living. Over 1,000 sailors, both men and women, are living onboard. They are arranged among over 3,000 tiny rooms below the deck. For visitors, it’s so easy to get lost. So the first thing the new sailors have to learn is their way around. The number of female sailors is much less than that of the males, taking about 5 percent of the total. But they play a key role in carrying out some special missions.
Also, you will be surprised by the high level of education of today’s sailors. The captain said that over 90 percent of the sailors are college graduates. Six hold Doctor’s Degrees and 45 have a Master’s. The whole team is young but vigorous（朝气蓬勃的）. The complex work on the carrier requires high management abilities for the commanders onboard(在船上).
【小题1】Why do we visitors get lost easily inside the carrier?

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.
Then look at the picture on the right. What do you see? A vase? Or two faces？Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can never see them at the same time.
“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 Park and Honey I shrunk the kids just make use of visual illusions.
【小题1】Why does the centre circle in Diagram A look smaller than that in Diagram B?

In the 13th century, the Italian traveler, Marco polo , traveled a long way to China , During his stay in China , he saw many wonderful things . One of the things he discovered was that the Chinese used paper money . In western countries , people did not use paper money until the 15th century . However , people in China began to use paper money in the 7th century .
A Chinese man called CaiLun invented paper almost 2000 years ago. He made it from wood . He took the wood from trees and made it into paper . He then put these pieces of paper together and made them into a book .
Now paper still comes from trees . We use a lot of paper every day ! If we keep on wasting so much paper , there will not be any trees on the earth . If there are no trees , there will be no paper . Every day , people throw away about 2800 tons (吨) of paper in our city . It takes 17 trees to make one ton of paper . This means that we are cutting nearly 48000 trees every day . Since it takes more than 10 years for a tree to grow , we must start using less paper now . If we don’t , we will not have enough time to grow more trees to take the place of those we use for paper .
So how can we save paper ? We can use both sides of every piece of paper , especially when we are making notes .We can choose drinks in bottles instead of those in paper packets . We can also use cotton handkerchiefs (手帕) and not paper ones . When we go shopping , we can use fewer paper bags . If the shop assistant does give us a paper bag, we can save it and reuse it later .
Everyone can help to save paper . If we all think carefully , we can help protect trees . But we should do it now , before it is too late .
【小题1】When he was in China , Marco polo ___________ .

   
Apple’s logo is one of the most familiar icons(图标) around the world. But what’s the story about the Apple logo? The image of the apple is obvious, because that’s the name of the company. What about the bite? The famous story is that the logo shows respect and honour for Alan Turing. He was the father of computer science. He researched artificial intelligence(人工智能) and unlocked German wartime codes(密码). However，after the war, he was put into prison，because of his beliefs. He could not stand the looking down and chose to bite a poisoned apple to end his life in the prison.
However, Rob Janoff, who designed the famous Apple logo, said, “It’s not the truth, but only a legend(传说, 传奇). The real reason why I designed it with a bite is very simple. I wanted people to get that it was an apple not a cherry (樱桃). When I go to markets to buy apples, I always mistake apples for cherries. It really has nothing to do with the scientist.”
Are you kidding? An apple is much bigger than a cherry. It’s very easy to tell. But if you use an apple to design a logo, some people may mistake it for a cherry.
【小题1】Both the apple and the cherry are almost the same actually in ________.

Almost every Chinese person can recite(背诵) the two lines of the famous poem, “Every grain on the plate comes from hard work ”. But sadly, many of us don’t actually get the real meaning of these lines: Don’t waste food.
A CCTV program reported that the food Chinese people throw away every year is enough to feed 200 million people for a year. Do we have too much food? Absolutely not. According to the UN World Food Program, there were 925 million hungry people around the world in 2011, especially in developing countries. Six million children die of hunger every year.
Chinese people are well-known for being friendly and generous. Many even feel that they lose face if their guests have eaten all the food on the table. Luckily, a number of people have realized the importance of saving food. What should we do in our daily lives to waste less food?
1. Don’t order too much in a restaurant. Only order as much as you want to eat. If you cannot eat all the food you ordered, take the rest of it home.
2. Don’t leave any food in your bowls while having meals.
3. Keep an eye on what food you have at home. Don’t buy too much, especially for vegetables and fruit.
【小题1】What’s the real meaning of the underlined sentence?

Have you ever seen a horse with toes(脚趾)？Millions of years ago, horses had many toes. They had four toes on each front foot. They had three toes on each back foot. The horses were no bigger than the cats.These small horses lived in the forest. The toes helped the horses run on the soft, wet ground.
At first, it was very hot in the forest. But the weather changed. It became very cold. Many trees could not live in cold weather. The trees died and fell. Open fields took the place of forests. The sun made the ground dry and hard.
Horsed began to change, too. They began to get bigger. This took a long time. On the dry, hard land, horses needed only their middle toes for running. Their middle toes became hard. After a long time, horses had only one hard toe on each foot. Now we call this hard toe a hoof.
【小题1】How many toes did a horse have millions of years ago?

When we talk about intelligence(智力)，we do not mean the ability to get good scores on certain kinds of tests or even the ability to do well in school．By intelligence we mean a way of living and behaving(表现)，especially in a new situation．If we want to test intelligence，we need to find out how a person acts instead of how much he knows what to do．
For example，when in a new situation，an intelligent person thinks about the situation，not about himself or what might happen to him．He tries to find out all can be，and then he acts immediately and tries to do something about it．Probably he isn’t sure how it will all work out，but at least he tries．And if he cannot make things work out right，he doesn’t feel ashamed(羞愧)that he failed，he just tries to learn from his mistakes．An intelligent person，even if he is very young，has a special outlook(看法)on life，a special feeling about life，and how he fits into it．
If you look at children，you’ll see the great differences between what we call “bright” children and “non-bright” children．They are actually two different kinds of people，not just the same kind with different amount of intelligence．For example，the bright child really wants to find out about life, and he tries to get in touch with everything around him; while the unintelligent(不聪明的) child keeps more to himself and his own dream-world：he seems to have a wall between him and life in general．
【小题1】According to this passage，intelligence is the ability to_________．
