Article: The following are letters to the editor of a school newspaper Dear editor, I'd like to express my opinion about grades. Students should be allowed to study without worrying about grades. Fortunately, most educators are becoming aware of the fact that students have different interests and abilities. I understand that grades are useful, but grades often limit creativity. Competing for better grades causes many students to turn down opportunities to pursue music, dramatics and sports. Grades force an arbitrary standard of success on everyone. I do not demand as some extremists do, that grades be removed immediately. However, I do believe that less emphasis should be placed on grades. I hope that someday grades will become optional at Village High School. Magdalena Smith Drama Club Dear editor, I'd like to say something about grades. Let's face the facts about grades. Grades perform three basic functions. First, grades motivate students to work at their highest level of competence. Second, they act as a reward for hardworking students and as a punishment to students who do not work hard. Finally, grades are used as an effective standard by which to measure student achievement. Good grades help students to get jobs and to get into university. I've spoken with a number of students who have jobs, and most of them say that they were hired primarily on the basis of their grades. My grades helped me land a part-time job and will help me get into university next year. I think grades are extremely important at Village High School. Simon Harper Science Club

answer:
D

Article: The challenge to drink to the limits of one's endurance has become a celebrated part of college life. In one of the most extensive reports on college drinking thus far, a 1997 Harvard School of Public Health study found that 43 percent of college students admitted binge drinking in the preceding two weeks (Defined as four drinks in a sitting for a woman and five of a man, a drinking binge is when one drinks enough to risk health and well - being ) Experts estimate that excessive drinking is involved in thousands of student deaths a year. And the Harvard researchers found that there has been a dramatic change in why students drink. 39 percent drank "to get drunk" in 1993, but 52 percent had the same objective in 1997. "What has changed is the across - the - board acceptability of intoxication ," says Felix Savino at UW - Madison. Many college students today see not just drinking but being drunk as their primary way of socializing. The reasons for the shift are complex and not fully understood. But researchers guess that it may have something to do with today's instant - satisfaction life - style--and young people tend to take into the extreme. While binge drinking isn't always deadly, it does have other, wide - ranging effects. Academics is one area where it takes a heavy _ (something paid, lost or suffered). Perhaps because alcohol increases aggression and affects judgement, it is also related to 25 percent of violent crimes and roughly 60 percent of vandalism on campus. Facing the many potential dangers, college campuses are searching for ways to reduce binge drinking.
Question: Why has "binge drinking" caused widespread concern?
Options: (A) Because it is directly responsible for the academic problem on campus. (B) Because it has claimed many young lives every year. (C) Because it has had harmful effects on the students' health and well - being. (D) Because it is in close connection with school violence.
answer:
C

question:
Article: Li Denghai, with his muddy boots and tanned face, may not look like he is one of China's famous agricultural pioneers. But the 61-year-old man from Shandong Province has made scientific breakthroughs , which made great contributions to China's food security . His main work has been in achieving the higher output of corn production. Li, who holds the world record for the highest output of summer corn, once says, "Corn has a life; it sings and dances. If you listen clearly, it can speak to you." He started his research in 1969 when he was 20 and just dropped out of a high school. He then read an article which pointed that corn output per mu in the USA was six times higher than that in China. He was shocked and set out to work on just a small piece of land _ to see if he could increase the output. He often went to the field with a flashlight late at night, if he had been away during the day. By careful nurturing he managed to double the output. Li Denghai was awarded the "China Award for Significant Contribution to the Maize Industry" in 2005, and the same year the company named after his own name came into the market on the Shenzhen Stock Exchange. Li, however, is never happier than when he is in the middle of his cornfields. "I can forget my tiredness when talking to my corns," he says.

Options: (A) he just graduated from an ordinary high school (B) he was shocked that the corn output in China was so low (C) he was only in his thirties (D) he wasn't really fond of his work
