Every day, he takes core courses from 7:10 am to 10:30 pm. Sometimes, Gan feels extremely stressed from the heavy workload. But he hopes that his three years of hard work toward the college entrance examination will change his life for the better. Gan is a typical Chinese student, as shown in a recently released survey. The new survey, which was conducted by the China Youth and Children Research Center and other foreign institutions, polled about 4,000 high school and vocational school students in China, Japan, the United States and South Korea. The five biggest frustrations listed by all the young people were: an over-busy school life, an empty personal life, dissatisfaction with their appearance, a lack of time for exercise and friends, and no spare money. Although some of the teenage problems were universal, there were big differences between the students when it came to the time they spent on schoolwork. For example, Chinese students spent the most time at school and on homework. Nearly 80 percent of them spent at least eight hours a week in school, and 56.7 percent spent two or more hours on their homework. By contrast (相比), only about 25 percent of US students, 20.5 percent of Japanese students, and 15 percent of Korean students had more than two hours of homework each night. The responses from the Chinese students also differed significantly from their peers in the other three countries when asked about their life goals. Only 16.7 percent of Chinese students said that they didn’t care much about their future, while the figure for that category was 72.4 percent for US students, 59.1 percent for the Japanese and 58.2 percent for the South Koreans. The survey found that Chinese students were more motivated than the other students to work hard for a better life. However, the survey also suggests that many Chinese high school students may feel unhappy under the pressure to succeed. Only 5.9 percent of the Chinese students—the lowest level—said they worried little in their daily life. 16．How long can Gan Xiaolin rest every week? 17．Which countries’ students were included in this survey? 18．What aspects did Chinese students spend the most time on? 19．How many US students have more than two hours of homework every night? 20．How many Chinese students worried little in their daily life? 四、书面表达 21．假如你是王欣，新的一年快到了，你及你家人的新年计划是什么呢？请你根据下表提示，写一篇英语短文，介绍一下你们的新年计划，然后在英语课上跟大家分享。 父亲 多做运动，保持健康 母亲 学唱歌，丰富生活 王欣 努力学习，提高成绩 要求：80词左右，可适当发挥。 _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 试卷第1页，共3页 试卷第1页，共3页 学科网（北京）股份有限公司 $$
