三、本节课的学习要点及考点

重点句型：

1.Like与 as的区别,like 说明相似关系 即二者在形态,性质上相似,但不等同.如:He has done a lot of good things like LeiFeng .他像雷峰一样做了许多好事. as 说明同一关系,指身份,意为 “作为,当做”如:Don’t treat me as a child I’m15.别把我当小孩子了,我都十五岁了. as还有 “像,按照”的意思.如:please do it as I told you .请照我的吩咐去做.I have the same idea as you.我和你想法一样.

2.Be able to 与can 的意义相当, can没有将来时和完成时,因此在shall, will have, 等后面,要用be able to 如:He is able to cook=he can cook,他做饭,I’ll be able to ride a bike.我就要会骑自行车了.

3.That can be done on the earth 定语从句修饰anything . 从句的为主用和是带有情态动词的被动语态,构成形式是 “情态动词+be+及物动词 的过去分词”.如:Tress can be planted in spring.树可以在春季栽种.

4.Can’t wait =can hardly wait 迫不及待,如:I can’t wait to go and see the deer in changling. 我迫不及待地想去看长岭看鹿了.The kids can’t wait for Christmas to come.孩子们等圣诞节都等不及了.wait还有名词 “等候,等待”的含义,如:We had a long wait for the bus.我们等公共汽车 等了很长时间.

5.In order to ….为了…表示目的,后接动词不定式,相当于so as to ,in order to   既可放在句首又可放在句中,so as to 只能放在句中,不能放在句首,它们的否定形式都是在to 前加not,即in order not to ,so as not to 它且们只能接动词原形,如果后接目的状语从句可用,in order that so that如:They did anything in order to /so as to make money,为了赚钱 他们什么事都做.

In order not to fail the exam, he studied fotr fourteen hours every day.为了考试不失利,他每天学习14小时.

She went to England last year in order that/so that she could learn standard English.她去年去了英国,为的是学习标准的英语.

6. 当think, believe, suppose imagine expect 等动词后接的宾语从句含有not 等否定词时,该否定应移至主句,即否定主句的谓语动词,如:I don’t think in will rain tomorrow我认为明天不会下雨.当主句的主语是第二,三人称时,否定式一般不转移.如:He supposes they won’t won the game .他猜想他们羸不了比赛.

注意:改写反意疑问时,当主句的主语为第一,二人称,反意疑问的主,谓要与从句一致,如果主句的主语是第三人称时,反意疑问的主谓与主句一致.如:he thinks he can make it doesn’t he?他认为他能办到,是吗?

I don’t think it will rain tomorrow will it?我认为明天不会下雨,是吗?

Can be found 是情态动词的被动语态,情态动词的被动语态结构为 “情态动词can/may/must/should +be +及物动词的过去分词,”如: it should be done at once,这件事应该马上办. he  must be prevented from going必须阻止他去.
