Ques:Read the following article and select the best answer. Article: Google, the Internet search and mapping company, has developed a car that can steer without a driver. Sometimes the reality is stranger than science fiction: Google is road-testing cars that steer, stop and start without a human driver. The goal is to "help prevent traffic accidents, free up people's time and reduce carbon emissions." says Sebastian Thrun, who is the project leader for the driverless car, or Carbot. By developing the car and the software that drives it, Google wants to change how people get from place to p1ace. Eric Schmidt, one of the company's top officials, said, "Your car should drive itself. It just makes sense." So far, the driverless autos have gone about 140,000 miles on California roads without people taking over the driving. Many of the roads are very busy or full of curves that challenge human drivers. The autos' software makes it possible to know speed limits, traffic patterns and road maps. The vehicles use radar, lasers and video cameras to find other cars and avoid people crossing streets. There has only been one accident during the testing. And in that case, the Carbot was hit from behind by a human driver when Goog1e's car was stopped at a red light. Engineers say the driverless cars are safer than autos with people behind the wheel because the computers react much more quickly than humans. The Carbot is still in very early testing stages. Experts agree that it will be years before you will be able to buy one. But it is likely that one day you will be sitting in the driver's seat of a driverless car. When the auto was first invented it was called a "horseless carriage". Now it seems that it is time for the "driverless carriage" to be part of our 1ives. Question: What's the main idea of the passage? - An auto revolution is on its way. - Google has developed a driverless car. - The Carbot has passed its early testing stages. - Science fiction has turned into reality.

Ans:Google has developed a driverless car.

Ques:Read the following article and select the best answer. Article: My family moved from Taiwan to a small town in central Georgia, where my dad got a visa for his family and a job. I had just learned English, and from what little I could gather from my classmates, Santa Claus would come down one's chimney and put toys in one's stocking on Christmas Eve! What a great country, I thought. After I looked up "stocking" in my Chinese-English dictionary, I knew _ . On that fateful night, after everyone went to bed, I took my longest, cleanest knee sock and attached it to a nail already on the mantel . Obviously, the previous owners of this house were no strangers to this Santa character. I woke up before everyone else on Christmas Day and ran to the fireplace. To make a sob story short, I was hit with the reality of an empty sock and the biggest lie ever told. I burst into tears, quickly took down the sock, and stuffed it in the back of a drawer. Santa was dead. Every December since then, the topic of Christmas memories would unavoidably come up, and I would amuse my friends with my poor-little-me story. I had to make it as funny as possible, or else I would cry. How could I know that Santa was just late? Nine years ago, on Christmas Eve, an older man with a white beard and a red cap knocked on my front door. He said, "I've been looking for you for twenty-five years." He handed me a bulging red stocking, winked, and left. On top of the stocking was a card. It read: "For Becky--I may have missed you in the second grade, but you've always lived in my heart. Santa." Through tear-blurred eyes, I recognized the handwriting of Jill, a friend I had met just two months before. I later discovered that the older man was her father. Jill had seen the hurt little girl underneath the thirty-something woman and decided to do something about it. So now I believe that Santa is real. I don't mean the twinkle-eyed character of children's mythology or the creation of American holiday marketers. Those Santas annoy and sadden me. I believe in the Santa Claus that live inside good and thoughtful... Question: By writing the passage, the author speaks highly of _ - friendship - parenting - religion - culture

Ans:friendship

Ques:Read the following article and select the best answer. Article: If music makes you smarter and exercise helps you to think, surely exercising to music can turn you into an intelligent person. A team of scientists from Ohio State University did experiments on 33 volunteers who were getting better from heart disease following operation. They found that people who exercised while listening to Italian musician Antonio Vivaldi's "The Four Seasons" did much better on language ability tests than without music. "Facts suggest that exercise improves the learning ability of people with heart disease," said the psychologist Charles Emery, who led the study. "And listening to music is thought to _ understanding. We just wanted to put the two results together," he added. The volunteers said they felt better emotionally and physically after working out with or without the music. But their improvement on the test doubled after listening to music during exercise. Scientists have proved that music can be good for health, education and well-being. It helps reduce stress, sadness and nervousness; encourages relaxation or sleep; wakes up the body and improves memory and thoughts. In medical fields, music is used widely for patients who have had head hurts before and after operation. "The Four Seasons" was used because of its moderate tempo and positive results in earlier research. "Exercise seems to cause positive changes in the nervous system and these changes may have a direct result on learning ability," Emery said. Scientists have been studying the results of music on understanding since the early 1950s. By 2000, psychologists were using Mozart's music, especially his violin pieces, to help children with speech disorders. Mozart was chosen because his music is not overexciting and has clear structures. A study showed students who listened to Mozart went on to score higher marks in an intelligence test. With important exams drawing near, your parents will not probably allow you to listen to music. But perhaps now you have good reasons to argue with them. Question: The text mainly tells us that _ . - music and exercise lead to relaxation or sleep - 33 volunteers work on music in medical fields - exercising to music makes people healthy and bright - scientists give suggestions on choosing music to exercise to

Ans:
exercising to music makes people healthy and bright
