第二節 閱讀短文，從所給選項中選出可以填入空白處的最佳選項。有一個多余選項。
Last month we asked our students about their free time activities. Our questions were about exercising, using of the Internet and watching TV. Here are the results.
We found that only fifteen percent of our students exercise every day. Forty-five percent exercise four to six times a week. Twenty percent exercise only one to three times a week. 17.
We all know that many students often go online, but we were surprised that ninety percent of them use the Internet every day. The other ten percent use it at least three or four times a week. Most students use it for fun and not for homework.
18. Only two percent of the students watch TV one to three times a week. Thirteen percent watch TV four to six times a week. And eighty-five percent watch TV every day! Although many students like to watch sports, game shows are the most popular.
It is good to relax by using the Internet or watching game shows, but we think the best way to relax is through exercise. 19. Exercise such as playing sports is fun, and you can spend time with your friends and family as you play together. And remember, "Old habits die hard." 20.
A. So start exercising before it's too late!
B. Many students like playing online games.
C. And twenty percent do not exercise at all.
D. It is healthy for the mind and the body.
E. The answers to our questions about watching television were also interesting.
答案：17.C
解析：前面提到了每天鍛煉、每周四到六次鍛煉、每周一到三次鍛煉的學生比例，分別是15%、45%、20%，這些比例相加為80%，所以此處應補充剩下20%學生的鍛煉情況，C選項“And twenty percent do not exercise at all.”（并且20%的學生根本不鍛煉）符合邏輯，能夠使數據完整。
18.E
解析：后面內容主要講述的是學生看電視的情況，包括不同頻率看電視的學生比例以及最受歡迎的電視節目類型，E選項“The answers to our questions about watching television were also interesting.”（關于看電視的問題的答案也很有趣）起到了引出下文的作用，符合段落過渡。
19.D
解析：前面提到“the best way to relax is through exercise”，后面進一步說明鍛煉的好處，如“Exercise such as playing sports is fun, and you can spend time with your friends and family as you play together.”，D選項“It is healthy for the mind and the body.”（它對身心都健康）是對鍛煉好處的總體概括，承接上文，引出下文具體好處的描述。
20.A
解析：前面提到“Old habits die hard.”（舊習難改），所以此處應呼吁學生開始鍛煉，養成好習慣，A選項“So start exercising before it's too late!”（所以趁現在還不晚，開始鍛煉吧！）符合語境，起到總結和呼吁的作用。
