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)——It’s a system that uses radio signals from satellites to show exact 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 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 advantage. It’s even hoped that one day space technology will take humans to their new housed in space.
Underwater Robot——Hercules is 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.

The sun gives energy and the earth receives the sun’s energy. The way the earth interacts with the sun’s energy can be displayed in a picture called the earth’s energy budget（预算）. It displays the sun’s energy that reaches us and how much of that energy is taken in and how much is thrown back by the earth and its air. Once the energy reaches the earth, some of it is taken by land and oceans. The amount of energy that is taken in influences the temperatures. The energy that is not taken in is thrown back to space.
Generally, the amount of energy coming in is equal to the amount of energy going out. So, we say the earth’s energy budget is balanced. If more energy was coming in than was going out, the earth’s temperature would increase. On the other hand, if too much energy is thrown back, and not taken in, we would see the earth’s temperature dropping.
Of all of the sun’s energy that hits the earth, about 67% is taken in by the land, oceans, air and clouds and about 33% is thrown back into space.
The picture above shows us how ________ hits the earth.
A. the high temperature B. the heavy rain C. the sun’s energyIn the 2nd paragraph, the underlined phrase “equal to ” means “______”.
A. less than B. the same as C. more thanPicture ______ shows us the main idea of the last paragraph.
A. B. C.
If too much energy is thrown back, we will feel ______on the earth.
A. cold B. hot C. warmThe amount of energy that is _______ influences the temperatures.
A. well balanced
B. thrown back
C. taken in
With the increasing numbers of smart phones and Chinese Internet users, micro blogging, known as Weibo in Chinese, has become more and more popular. Popular websites have created their own Weibo sites, which allow users to post a message of up to 140 words, along with pictures and videos（视频）.

“Well,” the farmer said, “but they________(be) very expensive.” The boy
_____(take) some changes(零钱）out of his pocket, “ I’ve got thirty-nine cents. Is that enough to take a dog?”

The Vieira family moved to the United States in 1981. At that time, they decided to stop speaking Spanish at home and only communicate in English. This was because they were now living in an English-speaking country.
Now the Vieira children are adults, and they sometimes travel to Spain to visit their family and friends. But they cannot communicate with them. Unfortunately this is common. When people move to new countries, they often leave their own customs and mother language behind. This is a mistake because there are many benefits to knowing more than one language.
One advantage of speaking more than one language is that you can communicate directly with more people around the world. You do not have to depend on others to talk for you, so you’re more independent. People who know only one language must use others to help them communicate
Furthermore, speaking a second language also allows people to experience other cultures and customs more effectively. Local expressions, vocabulary, and even jokes can have a powerful effect on a person’s understanding of another culture. So, knowing more than one language increases your knowledge of other cultures.
Finally, having more multi-language speakers improves relationships between countries. If people from different countries can communicate well, the world can become closer. Countries will then have more respect for each other and better understand each other’s problems.
The benefits of knowing more than one language are clear. In fact, there are no disadvantages. It is very sad that many people don’t try to learn another language. It is even worse when people let themselves forget their mother language and become silent. What is the passage mainly about?
| A．The benefits of learning other languages. |
| B．The reasons why people come toAmerica. |
| C．The importance of learning English. |
| D．How to learn another language. |
The passage begins with the experience of the Vieira family in order to_______.
| A．discuss the need for teaching a new language |
| B．introduce the passage’s main characters to the readers |
| C．describe the advantages of moving to another country |
| D．show the problems of speaking only one language |
The underlined phrase “multi-language speakers” means “people who know ______.”
| A．their mother language | B．a new language |
| C．more than one language | D．body language |
According to the passage, if you can speak more than one language, you can____.
| A．find a better job | B．make more friends |
| C．better understand history | D．communicate more independently |
Based on the last paragraph, which of the following is the worst?
| A．Not knowing another language. | B．Forgetting one’s mother language. |
| C．Refusing to learn another language. | D．Failing to communicate with others. |
Do you want to live a happier, less stressful life? Try laughing for no reason at all. That’s how thousands of people start their day at laughter Clubs around the world—and many doctors now think that having a good laugh might be one of the best ways to stay healthy.
The first laughter Club was started in Mumbai, India, in 1995 by Dr Madan Kataria. “ Young children laugh about 300 times a day. Adults laugh between 7and 15 times a day,” says Dr Kataria. “Everyone’s naturally good at laughing—it’s universal（通用的） language. We want people to feel happy with their lives.” There are now more than 500 Laughter Clubs in India and over 1,300 worldwide.
Many doctors are also interested in the effects of laughter on our health. According to a 5-year study at the UCLA School of Medicine in California, with laughing there is less stress in the body. Laughter improves our health against illness by about 40%.
So, what happens at a Laughter Club？ I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest--I wasn’t interested in laughing with a group of strangers, and I was worried about looking stupid. Our laughter teacher told us to clap our hands and say“ho ho ho, ha ha ha.” While looking at each other. However,Our bodies can’t tell the difference between fake（假的） laughter and real laughter, so they still produce the same healthy effects.
Surprisingly, it works! After ten minutes everybody in the room was laughing for real—and some people just couldn’t stop! At the end of the class I was surprised by how relaxed and comfortable I felt. So if you’re under stress, then start laughing. You might be very pleased with the results! In which country was the first Laughter Club started?
| A．Britain | B．America |
| C．Australia | D．India |

People believed for a long time that heart was the center of a person’s emotions. That is why the word “heart” is used in so many expressions about emotional situations.
One such expression is to “lose your heart” to someone. When that happens, you have fallen in love. But if the person who “won your heart” does not love you, then you are sure to have a “broken heart”. In your pain and sadness, you may decide that the person you love is “hard-hearted”, and in fact, has a “heart of stone”.
You may decide to “pour out your heart” to a friend. Telling someone about your personal problems can often make you feel better.
If your friend does not seem to understand how painful your broken heart is, you may ask her to “have a heart”. You are asking your friend to show some sympathy(同情) for your situation. Your friend “has her heart in the right place” if she says she is sorry, and shows great concern(关心).
If your friend says no to you, do not “lose heart”. Be “strong-hearted”. Sit down with him or her and have a “heart to heart” talk. Be open and honest about your situation. Then you may have a “change of heart” Then you could stop worrying and “put your heart at rest”. When bob loves Mary, you might say that he ___________________.

Scientists have made the world’s first human-sheep----with the body of a sheep and half-human organs(器官). Amazing, but true. The sheep is15percent human and 85 percent sheep. The breakthrough(突破)makes it possible to use animal organs in human bodies in the future. Professor Esmail Zanjani of University of Nevada, US, has spent seven years And over $9 million on the work. Zanjani took stem cells(干细跑) from the human body and put them into the sheep while it was still in its mother’s body. The stem cells made other cells that grew into organs. Zanjani believe that in the future such sheep might be used to help humans. Two months later a human-sheep is born, it has a liver(肝脏), heart, ling(肺) and brain that are part-human. These organs could be used to help people in need of them. There are different opinions about his work, however. Some say that scientists don’t have the right to create new creature(生物). Using animal organ might bring animal viruses(病毒) into human bodies. Others are afraid that the work might change sheep. But Professor Anjani has said that this is impossible.

How could we tell time if there were no watches or clocks anywhere in the world?
The sun is probably the world’s first “clock”, except in the far north, where the Eskimos(爱斯基摩人) live. There, it’s dark most of the winter, and light most of the summer. But in most of the world, people have used the sun as a clock. Even today, if you don’t have a clock, you can still know that when the sun shines, it’s day and when it’s dark, it’s night. The sun can also tell you if it’s morning, noon, or afternoon.
Some people live near the sea from the tides. In the daytime, for about six hours, water rises higher and higher on the beach. And then it goes down and down for about six hours. The same thing happens again at night. There are two high tides and two low tides every 24 hours. Seamen on the ship learn how to tell time by looking at the moon and the stars. The whole sky is their clock.
In some places in the world the wind comes up at about the same time every day or changes direction or stops blowing. In these places the wind can be the clock.
A sand clock is an even better clock. If you had fine dry sand in a glass shaped like the one in the picture, you would have what is called an hourglass. The sand in the hourglass goes from the top part to the bottom in exactly one hour. When the hourglass is turned over, the sand will take another hour to go back again From the passage we can know there are _______ways to tell time besides the clock and watch.
| A．3 | B．4 | C．5 | D．7 |
. The Eskimos in the far north can’t use the sun for a clock because________
| A．they know very little about the sun |
| B．the sun there never goes down in winter |
| C．it’s too cold for them to go out to watch the sun |
| D．it has long dark winters and long light summers |
. What does the underlined word “tides” mean in the passage?
| A．洋流 | B．潮汐 | C．海啸 | D．波浪 |
In which page of newspaper can you probably read this passage?
| A．News | B．Science | C．Advertisement | D．Sports |
What is the best title for the passage?
