It was so cold and snow was falling so heavily that the roads were covered with ice and a strong wind was blowing. Being outside in such weather was very unwise. However, Peter Lee had to walk home from work. Peter walked with difficulty along a country road, the cold wind beating against his chest. He thought, "If I wear my coat backwards, maybe, it will be a little bit warmer for me." He stopped walking, took off his coat, and put it on backwards. "That's much better," he said to himself happily. Walking on through the thickly falling snow, he was thinking about drinking a cup of warm coffee by the burning fireplace. A few minutes later, a car knocked down Peter. The driver hadn't seen him soon enough. When he tried his best to put on the brakes , the car skidded on the icy road. The frightened driver got out of the car and ran to see how the poor man was. After a while, a police car arrived. A policeman went up to see Mr Lee who was lying on the ground. He told the driver, "I'm afraid he's dead." The driver was so surprised. "This can't be the case, because I hardly touched him. Check my car carefully. There's not a mark on it." The policeman said, "I'm sure he's dead." "It's impossible," the driver said anxiously. "As soon as I hit him, I ran to help him. He was lying on the road, but he was breathing and there was no blood." "Did you touch him?" the policeman asked. "Yes, but only to turn his head around the right way," the driver answered. Question: Peter Lee wore his coat backwards _ . Options: A: to keep himself a little bit warmer B: to help walk forward more easily C: not to let others know him D: not to let the cold wind blow

Q: Read the article and select the best answer. Article: There are millions of people throughout the world who are either born blind or have become blind over the course of their lifetimes. It is unfair to take away the visual beauty of the world from these people. Doctor Humayun has created the world's first bionic eye that could change the life of every blind people in the world. Doctor Mark Humayun is a well respected professor at the Doheny Eye Institute in California. He has been working for years on creating a bionic eye that would allow blind people to see images just like a normal person does. His idea of the bionic eye is actually an eye that has been built in a small video camera. The test results show the bionic eye has given blind patients the amazing ability to see the scientists doing the tests. But the images are still blurry and we need much work before the eye actually becomes a regular implant into blind people. Humayun believes that he can go into production with the bionic eye over the next three to five years. A closer look at the bionic eye is amazing. The patient wears a special set of eyeglasses. All the signals are passed to the implanted eye. It's done by wireless technology. Humayun has created an invention that could change the lives of millions of people. Imagine a world in which someone would no longer fear about being blind. This could be considered a technological achievement. Question: Why is Doctor Mark Humayun well respected? Options: A: Because he has been working on a small video camera. B: Because he is a professor of a famous university. C: Because he invented a video camera for the blind.

*Question*
Read the article and select the best answer. Article: For a long time, humans have used technology to study the world around us, and Mars is the latest place we're using machines to explore. Besides the earth, the "red planet" is seen, as the one place in our solar system most likely to have life. Early last month, the first American robot, Spirit, landed on Mars without any problem. Opportunity, the second robot, landed on the planet more than a week ago. Scientists are very excited about these machines' safe landing on Mars. It means that now we have an excellent chance to look for water and other signs of life. So far, the robots have found some stones that could show Mars was once a wet and warm planet. But the trips made by Spirit and Opportunity were dangerous. Mars is often called the "death planet", because in the past its environment has been unfriendly to the robot explorers. Before Spirit and Opportunity, nearly forty spaceships had been sent to Mars since the 1960s. Two-thirds of them failed. The first spaceship, Korabl, sent in 1962 by Russia was among them. It broke apart near the earth. Question: For a long time humans think _ . Options: A: they can surely find life on Mars B: there may be life on Mars C: it's too late for them to explore Mars now D: Mars is the only planet that has life on it
