  • 第1题：

    Directions: Some people think that alluniversity students should study whatever they like. Others believe that theyshould only be allowed to study subjects that will be useful in the future, suchas those related to science and technology. What′s your view about what subjectuniversity students should study? You are required to write a compositionwithin 180 words, but no less than 150 words.


    答案：
    解析：
    People have different views about what subject university students should study, whether the one they like or only the one that will be useful in the future. People who believe students should only study subjects that will be useful in the future list several reasons. First, university courses like medicine, engineering and information technology can provide more job opportunities, career progression, better salaries, and therefore an improved quality of life for students who take them. Second, those subjects play the major role in new inventions, economic growth, and the society' s greater future prosperity. As far as I am concerned, university students should be free to choose their preferred subjects. In my opinion, students can study well if the learning content caters to their interest. Besides, the creative thinking patterns behind some theoretical subjects have potential value. In this sense, more students of art, history and philosophy are needed. In conclusion, although it might seem sensible for students to focus only on the most useful subjects, I personally assert that they have the right to study whatever they like.

    Passage1Children who spend more than two hours a day at a computer or watching television are more likely than others to have mental problems，scientists say.Researchers found that 11-year-olds who spent several hours in front of a screen each day did worse on mental health tests，no matter how much physical exercise they got. The University of Bristol study，published in Pediatrics，involved more than 1，000 children aged about 10.They also had the kids fill out questionnaires designed to gauge the kids' emotional well-being and behavior.The questionnaires contained 20 questions covering five sections-emotional difficulties，conduct problems，hyperactivity or inattention，friendships and peer groups and problems relating to friends and peer groups.The study found no direct evidence that sitting in front of a screen actually causes mental health problems. Instead，it suggests that children with difficulties，such as extreme shyness，are more likely to choose TV or computer games than sociable activities. In the study，children were asked whether they agreed，disagreed or somewhat agree with a list of statements，including，"I generally play alone or keep to myself" and，"I am often unhappy or tearful".They were also asked how much exercise they took and how long they spent at a TV or computer screen.According to the study，children who spent more than two hours a day at a screen had a 60% higher risk of mental problems than children who spent fewer viewing hours. The risk was only slightly higher in children who did little or no exercise."Physical activity is good for health in many ways，but it can't make up for long hours of screen viewing. Parents should consider limiting their children's screen viewing to no more than 2 hours a day，”said the study organizer，Angie Page.Previous studies have raised concerns that watching too much television can affect children's behavior in later life. A Canadian study found that those who watched most TV as young children performed worse at school, ate more junk food and had more trouble concentrating.How can children improve mental health according to the passage？
    A

    By limiting TV and computer use to less than two hours a day.

    B

    By getting more physical exercise.

    C

    By playing more educational computer games.

    D
