Section B, 2b 阅读语篇
What Do No.5 High School Students Do in Their Free Time
Last month we asked our students about their free time activities. Our questions were about exercise, use 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. And twenty percent do not exercise at all!
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.
知识点拨：
result n.结果；后果
percent n. 百分之……
online adj.& adv.在线(的);

The answers to our questions about watching television were also interesting. 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. It is healthy for the mind and the body. 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”. So start exercising before it’s too late!
知识点拨：
television n.电视节目；
电视机
although conj.虽然；尽管；即使

mind n.头脑；心智
body n.身体
such adj.& pron.这样的；那样的 类似的
such as例如；像……这样
together adv.在一起；共同
die v.消失；灭亡；死亡

五年级的高中生在空闲时间做什么？
上个月，我们向学生们询问了他们空闲时间的活动情况。我们的问题是关于锻炼、使用互联网和看电视。以下是结果。
我们发现只有15%的学生每天锻炼。百分之四十五的人每周锻炼四到六次。20%的人每周只锻炼一到三次。20%的人根本不锻炼！
我们都知道很多学生经常上网，但令我们惊讶的是，他们中90%的人每天都在上网。另外10%的人每周至少使用三到四次。大多数学生用它来娱乐而不是做家庭作业。
单元语篇自学
我们关于看电视的问题的答案也很有趣。只有2%的学生每周看一到三次电视。13%的人每周看四到六次电视。85%的人每天都看电视！尽管许多学生喜欢看体育比赛，但游戏节目是最受欢迎的。
通过上网或看游戏节目来放松是件好事，但我们认为最好的放松方式是锻炼。它有益于身心健康。运动等锻炼很有趣，当你一起玩的时候，你可以花时间和你的朋友和家人在一起。记住，“旧习惯很难改掉”。所以，在一切还来得及之前就开始锻炼吧！

单元写作指导
Write a report about your habits.
范文
My habits
I’m a 13- year- old middle school student. Many people have their good habits and bad habits and so do I.
I have some good habits. For example, I exercise every day. And I always eat vegetables and fruit. I think they can make me strong and healthy. I usually get up early in the morning and sleep early at night.
It is good for my health. I also like playing table tennis in the afternoon. It makes me happy and active.
However, I still have some bad habits. For example, I often play computer games or go on line for a long time. It's bad for my eyes. I usually watch TV all day on weekends, so I can’t have a good rest. Of course, I like junk food, too. And I eat it two or four times a week.
1. 写作思路：
本单元的写作话题是“介绍自己的习惯”，写习惯可以从以下几个方面去写。
任何一个人都有好习惯也有坏习惯，可从好习惯和坏习惯两方面客观的去写。
可以写生活习惯，可以写学习习惯，还可以写娱乐习惯，可多个方面介绍。
可以介绍这些习惯给你带来的好处和坏处，可以用实际的例子加以说明。
文章最后可以总结建议，谈一谈如何培养好习惯，减少坏习惯。
2. 注意事项：
第一，时态，写习惯这样的文章基本时态是一般现在时，这一点一定要注意，但如果涉及到举例说明，则根据具体情况，选择合适的时态。
第二，注意文章的逻辑和衔接。注意使用一些衔接词如：For example, also, and,
However等等
