【正文】 between them in maths. Boys scored better than girls in physics and chemistry. There were no sex differences in the life and environmental sciences. In addition to being tested, students in the project were asked how proficient they thought they were in maths and science. Students in some countries, such as Columbia and Kuwait, had an overly optimistic view of their sills. Meanwhile, some of the best students from Japan and Korea for example were needlessly pessimistic even though they did far better in maths than almost all of other students. Questions 17 to 20 are based on the passage you have just heard. 17. Of the 4 groups of students, who scored the lowest in maths according to the survey? 18. What kind of students are most likely to bee top scorers? 19. In what way do Columbian students differ from Japanese students? 20. In which subject did boys score higher than girls?Section A 1.

Q: What are they talking about?Section BPassage One Most people know what a hotdog is. It39。s stem, there are hundreds of water pipes that bring water and minerals from the soil all the way up to the leaves. As the ground turns dry, it bees harder and harder for the plants to do this. In severe droughts, plants have to fight to pull out any water available. Scientist Robert Winter has found out that when it is really bad, their water pipes snap from the tension like rubber bants. When that happens, the whole plant vibrates a little. The snapping pipes make noises 10,000 times more quiet than a whisper. Robert knows that healthy, wellwatered plants are quiet. He also knows that many insects prefer attacking dry plants rather than healthy plants. How do the insects know which are healthy plants and which are not? Robert thinks that the insects may listen for the plants that cry. And then they may buzz in to kill. To test this theory, Robert is using a device that can imitate plant cries. He attaches it to a quiet, healthy plant so that the plant sounds thirsty. Then he watches the insects to see if they attack more often than usual. If he is right, scientist could use the insects39。ve taken care of everything and I39。t understand why this book for selfstudy doesn39。re both excellent artists. Q: What does the woman imply about Joe and Core?7. M: Mary is in charge of the art and music section。ve been too busy to phone him. Q: What do we learn from the conversation?9. M: I39。ve heard it isn39。t very popular in the United States at the time. Few North Americans knew anything about this fastmoving sport. There was no money to pay professional players and there was little interest in football in high schools and colleges. When Pele and other international stars began playing in various US cities, people saw how interesting the game was and began to go to the matches. It is now mon for important games to have fifty to sixty thousand fans. Support from the fans is important to the football. The fans cheer enthusiastically for their favorite players and teams, who respond by playing better than before. In most World Cups, the home team, or the team from the host country usually plays better than most people expect. In 1966, 1974 and 1978, the home teams of England, West Germany and Argentina all won the World Cup. The World Cup is called that because teams from every continent have played in it. However, since the Cup began, all of the winning teams have been from Europe or South America. Teams from Asia or Africa always do well but they haven39。s smartest adolescence in mathematics and science are Singapore, according to a global survery of educational achievement. In the 3rd International Mathematics and Science Study, 13yearolds from Singapore achieved the best scores in standardized tests of maths and science that were administered to 287,896 s
