Everybody learns his own language by remembering what he hears when he is a small child, and some children, like boys and girls who live abroad with their parents, seem to learn two languages almost as easily as one. In school it is not easy to learn a second language because the pupils have so little time for it, and they are busy with other subjects, too. A man's mind is rather like a camera, but it takes photos not only of what we see but of what we feel, hear, smell and taste. When we take a real photo with a camera, there is much to do before the photo is finished and ready to show to our friends. In the same way there is much work to be done before we can keep a picture forever in our mind. Memory is the diary that we all carry about with us. Question: If you have a good _ , you'll have less difficulty in learning something. - teacher - camera - memory - family

Read the following article and select the best answer. Article: If you know something is bad for you, why can't you just stop? About 70% of smokers say they would like to stop. Drug and alcohol abusers struggle to give up the bad habits that hurt their bodies and destroy families and friendships. And many of us have unhealthy weight that we could lose if only we would eat right and exercise more. So why don't we do it? Some scientists have been searching for answers. They've studied what happens in our brains as habits form. They've found answers to why bad habits, once formed, are so difficult to kick. And they're developing ways to help us make the changes we'd like to make. Habits are a normal part of life, and are often helpful. " We wake up every morning, shower, comb our hair or brush our teeth without being aware of it," Volkow says. We can drive along familiar routes without really thinking about the directions. "When behaviors become automatic , it gives us an advantage, because the brain does not have to perform the action on purpose." Volkow says. This frees up our brains to focus on different things. One way to kick bad habits is to focus on your unhealthy habits. Then try your best to stop them. For example, habits can be linked in our minds to certain places and activities. You could develop a plan, say, to avoid walking down the hall where there's a candy machine. Try to avoid going places where you've usually smoked. Stay away from friends and situations linked to problem drinking or drug use. Another helpful way is to replace unhealthy habits with new, healthy ones. "It doesn't work for everyone," Volkow says. "But certain groups of patients who have a history of taking a drug can do something else like running and it helps them stay away from drugs." Question: What is the main idea of the passage? - Breaking bad habits. - Forming good habits. - Finding reasons for bad habits - Replacing bad habits with good ones.

There the land of the Navajo Reservation looks very much like the lunar surface. Among all the trucks and large vehicles were two large figures that were dressed in full lunar space suits. Nearby, a Navajo shepherd and his son were watching the strange creatures walk about, occasionally being watched over by other NASA workers. The two Navajo people were noticed and approached by the NASA people. Since the shepherd and his son did not know English, they asked the NASA people who the strange creatures were. The NASA people told them that they were just men that were getting ready to go to the moon. The shepherd became very excited and asked if he could send a message to the moon with the astronauts. The NASA officials thought this was a great idea so they provided a tape recorder. After the man gave them his message, they asked his son to translate. His son would not. Later, they tried a few more people on the Navajo Reservation to translate and every person they asked would chuckle and then refuse to translate. Finally, with cash in hand someone translated the message, "Watch out for these guys, they have come to take your land!" Question: When the older Navajo heard that the men in front of him were going to the moon, he _ . - felt frightened and ran away quickly - chatted excitedly with the NASA workers - got on the modern trucks and large vehicles for fun - tried to say something to the moon creatures
