Our questions were about exercise,use of the Internet and watching

10、 TV. 我们的问题是关于运动，因特网的使用和看电视的。 ?提问:句中的exercise和use是名词还是动词，为什么？,答案：是名词。因为它们位于about这个介词之后，它们若是动词，则要用-ing形式。,?注意：use of the Internet 因特网的使用（名词） use the Internet 使用因特网 （动词）,2. We found that only fifteen percent of our students exercise every day. 我们发现仅仅我们15%的学生每天都锻炼。,?【注意】percent做主语时，谓语动词的数要根据其后面的名词来确定。e.

11、g. Fifty percent of the students are boys. （50%的学生是男生。） Twenty percent of the meat is in the bowl. （20%的肉在碗里。）?【了解】动词+that引导的句子（叫宾语从句），句中的that不翻译，可以省略。,3. And twenty percent do not exercise at all! not at all 意为“一点也不”， not应和be动词、助动词或情态动词连用。 e.g. The story isnt interesting at all. 那个故事一点也没有趣。 They di

12、dnt enjoy the vacation at all. 他们根本不喜欢那次度假。 The old man cant use the computer at all. 那位老人一点也不会用电脑。,4. The answers to our questions about watching television were also interesting. 对我们提出的有关看电视的问题的回答也很有意思。?此句主要意思是The answers were also interesting. 主语是The answers（复数），故用were。?注意“.的答案”要用“answers to（介词）.

13、”这一固定搭配。e.g. the answers to our questions译为：我们问题的答案?注意“有关.的问题”往往用“questions about .”这一固定搭配。e.g. our questions about watching television 译为：我们提出的有关看电视的问题,5. Although many students like to watch sports, game shows are the most popular. although 连词，“尽管，虽然”。用英语表达“虽然.但是.”时，although 和but不能在同一句中同时出现。即：有alt

14、hough 就没有but，反之亦然。 虽然许多学生喜欢观看运动，但是游戏节目还是最受欢迎的。,e.g. 尽管他离家很早，但是他还是迟到了。Although he left home early, but he was late. ()?Although he left home early, he was late. () ?He left home early,but he was late. () ?He was late,although he left home early. (),中考链接 My cousin knows a lot about geography, _ he is

15、only four years old.A. because B. soC. although,C,6.Its good to relax by usingbut we think the best way to relax is through exercise.虽然通过使用.来放松是好的，但是我们认为最好的放松方式是通过锻炼。 1）although和 but不能同时出现。 2）Its good to relax by using是Its +形容词+不定式（to do sth.）的句型。此句中的it=不定式,所以翻译要把it译成不定式的意思。e.g. Its good to relax by

16、 using译成通过使用.来放松是好的. 3) “（做.事）的方式”要用“the way to (do sth.)”,7. Exercise such as playing sports is fun such as意为“像这样”，表示列举。 结构常为：名词+ such as + 例子 e.g. She likes animals such as rabbits and birds. 她喜欢像兔子、小鸟这样的小动物。,8. Old habits die hard. 旧习难改。 这是英语中的一句谚语，表示习惯一 旦养成，并非朝夕即可改变。其中， die hard表示“（旧习惯，传统等）难以 改变

17、；根深蒂固”。 本句的hard是副词，表示“费力地；艰难地 努力地” e.g. Its important to work hard. 努力工作是重要的。,9. So start exercising before its too late.所以赶快锻炼起来，不要等到来不及的时候。?its too late 为时太晚；来不及了 e.g. Now you know youre wrong, but its too late. 现在你知道你错了，但是已经太晚了。?before its too late“在太晚之前”即为：“不要等到为时已晚；不要等到来不及时；趁着还来得及时”,1. 读2b中的短文。2. 根据2e的调查结果写一个报告。,Good-bye,U盘、电脑坏了？教学资料不见了？以前的资料没保存？每一届重复劳动？找不到精品课件、试题、教案反思？各大文库价格昂贵？来【163文库】吧，你可以：上传分享资料赚取零用钱；创建教学空间，分类收藏存储资料；方便下届使用；百万教学资源供你下载；【平台地址：】,
