课文讲解

The other day,my friends and I talked about the rules that we have in school. At our school,we have to wear uniforms every day.The problem is that all my classmates think the uniforms are ugly.We think the young people should look smart and so we would like to wear our own clothes .Our teachers believe that if we did that,we would concentrate more on our clothes than our studies.We disagree. We would feel more comfortable and that is good for studying.If we can't do that,we should be allowed to design our own uniforms.That would be a good way to keep both teachers and students happy.

前几天我和我的朋友们谈论关于我们学校里的校规. 在我们学校里,我们必须每天都穿校服,可问题是我们班所有的同学都觉得校服很难看 前几天我和我的朋友们谈论关于我们学校里的校规.在我们学校里,我们必须每天都穿校服,可问题是我们班所有的同学都觉得校服很难看.我们认为年轻人应该看起来时尚些,所以我们想穿我们自己的衣服.老师们认为如果我们都穿自己的衣服,那么我们的注意力会比较多的集中在衣服上而不是学习上.我们却不这么认为.我们觉得那样会感觉更舒服些,而且对我们的学习是有好处的.如果我们不可以穿自己的衣服,那我们应该被允许来设计自己的校服.那样做就可以让老师和学生都如其所愿了.

It's also probably a good idea for parents to allow teenagers to study in group during the eveving.I know we get nosiy sometimes,but we learn a lot from each other.We also think that vacations should be longer. At present they're too short.Long vacations would give us time to do things like volunteering.Last summer I had an opportunity to volunteer at the local hospital,but I could't because I had to go back to school. It would be a good experience for me because I want to be a doctor when I'm older.

家长允许青少年晚上一起学习,这或许也是个好主意. 我知道有时候我们会很吵,但我们彼此确实能够学到很多东西. 我们还认为假期应该更长些 家长允许青少年晚上一起学习,这或许也是个好主意.我知道有时候我们会很吵,但我们彼此确实能够学到很多东西.我们还认为假期应该更长些.现在的假期太短了,假期更长些可以让我们有时间做一些比如志愿者之类的事情.我去年夏天有机会到当地的医院去做志愿者,但我因为必须要返校所以没能去成.这本来对我是个很好的经历,因为我长大后想做一名医生.

单元讲解（下）

重点语法

1.语态： 　①英语有两种语态：主动语态和被动语态　 　　主动语态表示是动作的执行者 　　被动语态表示主语是动作的承受者　 　 Cats 　eat 　fish. 　　　（主动语态）猫吃鱼。 　 Fish is eaten by cats.　(被动语态)鱼被猫吃。 ②被动语态的构成 　　由“助动词be ＋及物动词的过去分词”构成 　　助动词be 有人称、数和时态的变化，其变化规则与be 作为连系动词时完全一样。

2 时态被动语态结构例句 一般现在时am /is/ are +V.过去分词 如:English is spoken in many countries. 一般过去时was /were +V,过去分词 如:This bridge was built in 1989. 一般将来时 will be + V,过去分词 如：All the work will be done very soon. 情态动词 can/should/may /must/…+be+V.过去分词 如:The work must be done right now.

3 被动语态的用法 a 当我们不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者 如：His new car was stolen. 他的新车被偷了。（谁偷的，不知道） b 或者只需强调动作的承受者时，要用被动语态。 The car was parked in front of the house. 车被停在房子前。

被动语态练习 ( ) 1 The People's Republic of China ___ on October 1, 1949. A. found B. was founded C. is founded D. was found ( ) 2 English ____ in Canada. A.speaks B.are spoken C. is speaking D. is spoken ( ) 3 This English song___ by the girls after class. A. often sings B. often sang C. is often sang D. is often sung ( ) 4 This kind of car ___ in Japan. A, makes B. made C. is making D. is made ( ) 5 New computers ___ all over the world. A. is used B. are using C. are used D. have used

倒装句 由so＋助动词(be/do/will/have)/情态动词＋主语 意为：…也是一样 　　She is a student. So am I.　 她是一个学生，我也是。 She went to school just now. So did I . 她刚才去学校了，我也是 She has finished the work. So have I . 她已经完成了工作,我也完成了。 She will go to school. So will he.　 她将去学校，他也是。

think about 与think of 的区别 ①当两者译为： 认为、想起、记着时，两者可互用 I often think about/ of that day. 我经常想起那天。 ②think about 还有“考虑”之意 ，think of 想到、想出时两者不能互用 At last, he thought of a good idea. 最后他想出了一个好主意。 We are thinking about going Qinzhou. 我们正在考虑去钦州。
