It seems that there’s a good reason why dogs are always seen as man’s best friend. Scientists have found that dogs are the only animals that can read emotion(情感)in faces much like humans. The finding suggests that like an understanding friend, dogs can see if we are happy, sad, pleased or angry.
When humans look at a new face, their eyes usually look across the left, falling on the right hand side of the person’s face first. A possible reason for this is that the right side of the human face is better at expressing emotions.
Scientists have now shown that pet dogs also have “left gaze bias(左视偏好)”, but only when looking at human faces. No other animal has been known to do like this before. Dr. Kun Guo with his team showed 17 dogs the pictures of human, dog and monkey faces as well as something else. The dogs’ eyes and heads show a strong left gaze bias when the animals see human faces. But this did not happen when they were shown other pictures, including those of dogs.
Guo suggests that over thousands of years living with humans, dogs may have developed the left gaze bias as a way to guess our emotions.
“Recent studies show that the right side of our faces can express emotions better than the left. If true, then it makes sense for dogs and humans to see the right hand side of a face first.”Why are dogs seen as man’s best friend according to the passage?
| A．Because dogs are the closest animals to humans. |
| B．Because dogs can read the emotions in humans’ faces easily. |
| C．Because dogs can understand us better when we feel sad. |
| D．Because dogs are good at expressing emotions. |
The dogs’ left gaze bias helps them _______.
| A．get along well with humans |
| B．express emotions quickly |
| C．have more understanding friends |
| D．remember more new faces |
The passage mainly wants to tell us that _______.
| A．dogs have been man’s best friends for thousands of years |
| B．humans have a “left gaze bias” |
| C．the “left gaze bias” works on all animals |
| D．dogs can read emotions the same as humans |

Stephen Hawkins was born in Oxford, England on 8th January, 1942. He went to school in St. Albans—a small city near London. Although he did well, he was never top of his class. After leaving school, Hawking went first to Oxford University where he studied physics, then he went to Cambridge University where he studied cosmology. As he himself admits, he didn’t work hard. He was a very lazy student, and did very little work. However, he still got good marks.
It was at the age of 20 that Hawking first noticed something was wrong with him. He started to bump（碰撞） into things. When he visited his family at Christmas time, his mother was so worried that she made him see a doctor. Hawking was sent to hospital for tests. Finally, the result came back. Doctors said they had no way to help him. He would die before he was 23.
At first, Hawking became very sad, after a while, though, he began to see his life in a different way. As he later wrote, “Before my illness was diagnosed（诊断）, I had been very bored with life. There had not seemed to be anything worth doing. But shortly after I came out of hospital, I suddenly realized that there were a lot of worthwhile things I could do.” Hawking married, found a job at Cambridge University, and had three children. He also went on to do some of the most important scientific research.
Today, Hawking still works at Cambridge University as a professor. He strongly believes that his story shows that nobody, however bad their situation is, should lose hope. “Life is not fair,” he once said. “You just have to do the best you can in your own situation.” As a university student, Stephen Hawking ________.
| A．worked very hard |

Have you ever asked your relatives or friends if there is Wi-Fi in their houses Have you ever searched for Wi-Fi when you are at restaurants or hotels. The answers will probably be "Yes". Most of us want Wi-Fi everywhere as if we can't live without it. But we can only use free Wi-Fi in some public places. We still have to spend some money accessing(连接)the Internet at most time. Here comes a piece of good news.
A rich, powerful organization in the USA called the Media Development Investment Fund (MDIF) has decided to change the age of online computing (计算) completely by giving free Wi-Fi to every person on Earth. They will send up hundreds of satellites into low Earth orbit(轨道)in 2015.
This is because they have made a survey and found that only 60% of the world's population have been able to get information on the Internet. And this is also because many countries are unable to offer people the necessary infrastructure(基础设施)to access the web.
We can expect to use free Wi-Fi everywhere in the near future.
| Present situation |
●Many of us want Wi-Fi everywhere as if we can't live without it. ●Accessing the Internet |
| What the organization will do |
●MDIF has made a decision to send up |
| Reasons |
●Only ●Many countries can't |
| What we can expect |
●Free Wi-Fi will |
Usually, students are not encouraged to run or jump around in the corridor (走廊). However, students in a British grammar school really enjoy running on the corridor tiles (瓷砖) and their teachers even encourage them to do that.
Why? It is because the corridor was built with special kinetic (动能的) tiles. When students jump on the tiles, electricity will be produced. After one year, the electricity produced from the tiles can fully charge 853 mobile phones or power(供电) an electric car to drive seven miles. It’s amazing, isn’t it?
The corridor tiles are really a brilliant invention. Students can not only play on the corridor, but also help power the lights in their school corridors and other equipment in their classrooms. Besides, this is a good way to teach students to be creative. They will be inspired to be scientists, inventors and engineers in the future to find clean energy for all humans.
The inventor of the magic corridor tiles is Laurence Kemball-Cook. He was once a student in this school. Now, he is CEO of his own company. The corridor tiles are not Laurence’s only invention. He has also invented a special dance floor, which can be used at music festivals. It allows dancers to charge their mobile phones while they are dancing on the dance floor.Why do the students in the passage enjoy running on the corridor tiles?
| A．Because the corridor tiles are expensive. |
| B．Because the teachers ask them to do that. |

| A．over 800 mobile phones |
| B．all the lights of the school |
| C．an electric car to drive 70 miles |
| D．the lights and other equipment in their classrooms. |
The underlined word “inspired” most probably means “ _________”.
| A．encouraged | B．forced |
| C．trained | D．allowed |
