2012高中英语 Module3 Music Grammar学案 外研版必修2

Module 3 Music (Grammar)

Learning aims:

1.To master the use of Adverbial clause of time( 时间状语从句)

2.The usage of the Past Perfect Tense（过去完成时用法）

Important and difficult points:

1.The difference between “when, while, as”（引导时间状语从句异同）

2. It is/was …that(who)…强调句式用法

一．时间状语从句

时间状语从句主要用于说明主句动作的时间。其引导连词主要有when, while, as, after, before, until, as soon as 等。

1.通过观察以下例句，总结when, while, as引导时间状语从句的异同。

He came in when / while/ as we were talking.

I was about to tell her the secret when someone patted me on the shoulder.

While I was reading last night, she was watching TV.

As she was watching TV, she was doing her homework.

相同点：在表示_________ 时，三个词可以通用，从句中的谓语动词必须是_______ 性的。不同点①when既可表示“一段时间”，与持续性动词连用; 又可表示“时间点”，与瞬间动词连用。

②while 从句只与持续动词连用，含义相当于“during the time ”

③ as强调主从句同时发生，常与when和while 通用，译作“一边……一边……”

“随着”。

2.由as soon as 等引导的表示“一……就……”的时间状语从句。

As soon as 引导时间状语从句，表示从句的动作一发生，主句的动作随即就发生，常译作“一……就……”。例如：

As soon as she heard the news, she came to tell us about it.

二．过去完成时

结构：had+过去分词

用图表示为↓————↓————↓————————→

过去完成过去现在将来

含义：过去完成时以过去为起点，动作发生在“过去的过去”。过去完成时是一种相对时态，必须有“过去”参照时间才能使用。过去完成时常用3种方式表“过去”的参照时间。

①根据上下文找出“过去状语”和“过去动词”

I was very sad at his death. We had been good friends since our childhood.

②用介词短语by 1981,by then, by the end of last week, before then, until/till

then等。

By the end of 1960s, their music had changed completely.

③when, before, until, by the time +(过去时态)时间状语从句

The train had already left when I got to the station.

三．It is/was …that(who)…强调句式

强调句的基本结构是：It +be +要强调部分+ that/who +句子其他部分，被强调的部分指人时用who/that,其他情况用that.例如

John wore his best suit to the party yesterday.

①强调John.

It was John who/that wore his best suit to the party yesterday.

②强调 best suit

It was his best suit that John wore to the party yesterday.

③强调 yesterday

It was yesterday that John wore his best suit to the party.

注意：

1）强调结构中的时态，主句与从句应一致。

It was my brother who knew him best.

2)强调主语时，从句中的谓语动词在人称和数上应与强调部分保持一致。

It is I who am hungry.

3) 如果强调一般疑问句中的成分时，要用一般疑问式：

Is/Was + it + 被强调部分+that/who + 句子剩余部分

Was it my brother who told you this?

4) 强调特殊疑问句中的成分时，要用其特殊疑问式：

特殊疑问词+is/was +it +that+ 句子剩余部分

Who was it that broke the window?

5)强调结构的否定式是：

It is/was not+被强调部分+that/who+句子剩余部分

It was not until I saw her that got the news.

高中情态动词练习(附答案)

高中情态动词练习(附答案) 一、单项选择情态动词 1．What a pity! Considering his ability and experience, he ___________ it better. A．need have done B．must have done C．can have done D．might have done 【答案】D 【解析】 【详解】 考查虚拟语气中的情态动词。句意：真遗憾啊！考虑到他的能力和经验，他也许可以做得更好。can have done较少使用此结构，表示对过去行为的怀疑；用于疑问句时意为“难道 真的做了吗”，表示怀疑；need have done需要做某事，实际上却未做（表示虚拟语气）；must have done一定做了某事（表示对过去发生的事情的肯定推测）；might have done表示对发生过的事情的推测，意思是“可能已经”或“也许已经”，用于肯定句中。故D正确。【点睛】 本题是高考必考考点，一定要牢记句型意思。must have done过去肯定做了某事。should have done本应该做而实际未做。can’t have done过去不可能做了某事；shouldn’t have done 本不应该做而实际做了。need have done本有必要做某事而没做；needn’t have done本没有必要做某事；注意没有mustn’t have done的形式。 2．Most of the top leaders expressed a common desire at the UN conference, ______ that different cultures ______ coexist with tolerance. A．the one ; must B．the one ; should C．one ; must D．one ; should 【答案】D 【解析】 【详解】 考查替代和情态动词。句意：大多数高层领导人在联合国大会上表达了一个共同的愿望，即不同的文化应该与宽容共存。大多数高层领导人在联合国大会上表达了一个共同的愿望，即不同的文化应该与宽容共存。替代表泛指的单数名词，通常用one替代。此处用one替代前面的a desire，是同位语；结合句意第二空用情态动词should“应该”。故选D。【点睛】 that ,it ,one 代指前面的名词时的用法 1.one 指代前面出现的可数名词，是泛指。可以和冠词连用，也可以有自己的定语。一般不能用做特指，但和定冠词连用时可以是特指。如： Please show me the cup, the red one on the shelf. 2.It 指代前面提到的单数名词，相当于the one。当one是泛指的时候，指的是同名异物，it是指同一物体.如： ----Do you want the cup ? ---Yes ,I want it. 3.that通常用来代替前面出现的可数名词\不可数名词,主要是用来避免重复。如： The weather of Guangzhou is hotter than that of Beijing.

高中英语语法 情态动词教学案

英语高考专题复习讲与练15 情态动词 一、考点聚焦 1、情态动词的基本用法 (1)can、be able to 和could ①can和be able to都表示能力，意思上没多大区别。但can只有现在和过去时，而be able to则有更多的形式。但当成功地完成某一具体动作时，通常不用could而用was/were able to 来表示。这时was/were able to 相当于managed to，表示经过一番努力，终于能够完成某事。如： Can you use chopsticks? The wounded man still was able to get to the village and was saved in the end. ②can和could can和could都可以表示能力、技能、许可、建议或请求和可能性。但比较委婉客气地提出问题或陈述看法，一般用could，回答时则用can。如： Could you help me carry the bag? Can I help you? (2)may/might ①may/might表示可能，但may比might可能性大。如：-Why is n’t he in class? He may be sick.(生病的可能性较大) — He might be sick.(生病的可能性较小) ②may/might表示“允许”，may用于现在时或将来时，might常用在间接引语中表过去时，但might也可用于现在时间，表示比较委婉的语气，回答用may。如： He says we may leave. He said we might leave. ③may / might 表示建议或请求，但might比may 更客气，意思更肯定而无过去时态的含义。 Yes, you can / may. —May / Might I use your bike? — No, you mustn’t （3）must ①must表示必须，应该，没有时态变化。如： You must do everything as I do. ②must表示肯定的推测。如： The light is still on, so he must be at home. ③mustn’t 表示禁止做某事。如： You mustn’t smoke in the office. （4）have to have to 表示“必须、不得不”，是由于某种外界（客观）原因而“必须”，“不得不”做某事，也可表示经常的或习惯性的事“必须”做。have to的否定形式表示不必。have to可用于多种时态中。如： You will have to clean your own boots when you join the army.
