1. Which parts need to be improved? 哪些局部需要被改善?

辨析:need to be done; need doing与need to do

(1) need doing=need to be done 需要被…现在分词doing表被动“需要被做〞,相当于need to be done。

My watch needs repairing. =My watch needs to be repaired.我的表需要修了。

(2) need后加不定式,证明need为实义动词,而非情态动词,这时need有人称和数的变化。

He needs to get up early. 他需要早起。

【小试牛刀】单项选择。

① Something is wrong with my car. It needs _____.

A. repair B. to repair C. repairing D. to be repair

② My alarm clock doesn’t work. It needs ______.

A. to be repaired B. repairC. to repair D. for repairing

③ My hair needs cutting.= My hair needs ______ ______ _______.

2. What or who is causing these problems? 什么或谁将会导致这些问题?

cause用作动词,当“引起,造成,使得〞讲。一般指引起或造成不好的结果。

cause sb. sth.= cause sth. to sb.(后接间接宾语+直接宾语)为固定用法。

He caused his parents much trouble.= He caused much trouble to his parents.

他给父母带来很多烦恼。

【小试牛刀】改为同义句。

① It caused him lots of worries. =It caused lots of worries ____ him.

【语法点拨】

本单元复习现在进展时、used to句型、被动语态、现在完成时和情态动词。

现在进展时

〔1〕含义:表示正在发生或进展的动作。

〔2〕根本构造: .

下载后可自行编辑修改,页脚下载后可删除。 主语 + be + 现在分词〔be 的形式随主语的变化而变化〕

〔3〕根本用法:

①表示现在正在进展的动作。特征:常常与now或具体的时间连用,有时句中会有感官动词来提示,或通过上下文来暗示。

②表示现阶段一直进展的动作。这类动词常常是延续性动词。常于at present, this

week, these days等连用。

③表示主语的特征、性格、能力等。

现在完成时

〔1〕含义:表示过去发生的动作对现在还有影响。

〔2〕根本构造:主语 + have / has + 过去分词

〔3〕根本用法:

①表示过去发生的动作,但强调对现在产生影响。特征:不能与表示具体的时间状语连用。

②表示过去发生的动作或存在的状态一直延续到现在,还可能继续下去。常常与since, for, in the past + 时间名词,in the last +时间名词等时间状语连用,而且谓语动词要求是延续性动词。

③表示一种“经历或体验〞,即可以表示经历过也可以是从来都没有经历过。

被动语态

初中阶段我们学习了七种被动构造,归纳如下:

〔1〕一般现在时是被动语态:am / is / are + 过去分词

〔2〕现在完成时的被动式: have / has + been + 过去分词

〔3〕现在进展时的被动式:am/ is/ are + being + 过去分词

〔4〕一般过去时的被动式:was / were + 过去分词

〔5〕过去进展时的被动式:was / were + being + 过去分词

〔6〕过去完成时的被动式:had + been + 过去分词

〔7〕一般将来时的被动式:will / be going to be+ 过去分词

〔8〕含有情态动词的被动式:

情态动词+be +动词的过去分词。

情态动词 .

下载后可自行编辑修改,页脚下载后可删除。 情态动词表示说话人对某一动作或状态的态度,如认为“可能〞、“应当〞、“必要〞等。情态动词本身有一定的意义,但不能单独作谓语,也没有人称和数的变化。后面一般跟动词原形。

used to 构造

used to意为“过去常常做某事〞,指的是过去的习惯性动作,目的在于与现在形成对照。used to是个情态动词,其中的to是不定式符号,后面跟动词原形。在美式英语中。它的疑问式是:Did +主语+use to do sth.?否认式是:主语+didn't use……在英式英语中,它的疑问式应当是:Used +主语+to sth.?否认式应当是used not to或use〔d〕n’t to。

He used to stay up late. 他过去常熬到很晚。
