II.情态动词的重点知识
表示“能力、许可”的can和may
表示能力的情态动词用can/could
A computer_____think for itself; it must be told what to do.
A.can’t B.mustn’t C.may not D.might not
表示许可时用may/might ,can/could 都可以,但在问句中用could…?或might…? 以使口气委婉客气,其回答一定要用can或may,以使回答口气明确(must表示一定,必须,mustn’t表示禁止,不许可)。
①—Could I call you by your first name? —Yes, you____
A.will B.could C.may D.might
②Johnny, you_____play with the knife, you_____hurt yourself.
A.won’t/can’t B.mustn’t/may
C.shouldn’t/must D.can’t/shouldn’t
在肯定句中could不可以用来表示过去某一特定场合的能力,而要用was/were able to。
The fire spread through the hotel very quickly but
everyone_____get out.
A.had to B.would
C.could D.was able to
表示“推断、判断”的can
may,
must
在肯定句中都可以用来表示可能。在含义上must语气最肯定,may表示的是事实上的可能性。
Peter______come with us tonight, but he isn’t very sure yet.
A.must B.may C.can D.will
而can表示的是逻辑上的可能性:
Mary is in poor health. She can be ill at any times.
在否定句中只能用can和may。所以can’t时用以代替mustn’t,语气比may更肯定。中文可以翻译为不可能。

定语从句
与
并列句
定语从句与并列句的主要区别在于:并列句有像and,but,so等并列连词或两个句子用分号连接,这时就不能再用引导定语从句的关系词了。
①Mr Li has three daughters,none of _____ is an engineer.
②Mr Li has three daughters,but none of _____ is a dancer.
从结构上看,①小题是定语从句,故填whom;
②小题有并列连词but,是并列句,故填代词 them。
定语从句
与
状语从句
定语从句的前面有名词作先行词,而状语从句没有先行词。
This is the place where we used to live a few years ago.
这是几年前我们居住的地方。(定语从句,先行词为the place)
Let’s go where we can find a better job.
我们到能找到更好的工作的地方去吧。(地点状语从句)
定语从句修饰、限制、说明名词,只能放在先行词的后面,而状语从句说明动作发生的情况,并且可以放在主句的前面。
Do you know the time when the class is over? 你知道下课的时间吗?(定语从句)
It was already five o’clock when the class was over.
=When the class was over, it was already five o’clock.
当下课时己经是5点了。(时间状语从句)
When, where和why在引导定语从句时可以用“介词+which”的结构来替换,在引导状语从句时却不行。
This is the factory in which (where) his father once worked.
这就是他的父亲曾经工作过的那个工厂。(定语从句)
Put back the book where it was. 把书放回原处。(状语从句)
定语从句中的关系词在从句中充当某种句子成分,因此去掉它则从句成分不完整;而结果状语从句中的连接词在从句中不作任何成分,去掉后从句的成分仍然完整。
It is such an interesting book as we all like. 它是我们大家都喜欢的如此有趣的书。
(as用作动词like的宾语,它引导的是定语从句)
It is such an interesting book that we all like it.
它是一本如此有趣的书,我们大家都喜欢它。
(that不充当句子成分,故它引导的是结果状语从句)
定语从句
与
同位语从句
定语从句在复合句中相当于形容词,对先行词起修饰、描述或限制的作用,与先行词之间有从属关系。同位语的作用相当于名词,对前面的名词给予补充说明或进一步解释,是前面名词的具体内容,与先行词之间是同位关系。
The news that she had passed the exam made her parents very happy.
她考试及格的消息使她父母亲很高兴。(同位语从句)
此句中的同位语从句 The news that she had passed the exam
可以改写成表语从句:The news is that he passed the exam.
The news that he told us interested all of us.
他告诉我们的消息使大家都感兴趣。(定语从句)
The news that he told us 是定语从句,此句不能改写为:The news is that he told us.
定语从句
与
强调句
强调句的结构为“It is/was+被强调部分+that+从句”。被强调部分可以是除谓语以外的任何成分,当被强调部分是人时,还可用who代替that。这一句型中,一定不能因为被强调部分是表时间或地点的词就用when或where代替 that。
①It is on the morning of May 1st _____ I met Liang Wei at the airport.
②It is the factory _____ Mr Wang works.
从结构上看:
①小题是强调句,故填 that。
②小题则是定语从句,用上述方法转换便知the factory前差个介词in,故填 where。
十三、强调句
强调的类别
说 明
例 句
It is (was) +被强调部分+that(who)…
为了强调句子的某一成分(通常是主语、宾语或状语),常用强调结构:
It is (was) +被强调部分+that(who)…
表示强调的it在这种结构的
句子中作主句的主语。
原始句:Last night I saw a film in the Youth Palace.
强调主语:It was I that (or: who) saw a film in the Youth Palace last night.
强调宾语:It was a fiml that I saw in the Youth Palace last night.
强调地点状语:It was in the Youth Palace that I saw a film last night.
强调时间状语:It was last night that I saw a film in the Youth Palace.
一般讲,原句的谓语动词如果是现在或将来各种时态,用It is…that (who)…;如果原句谓语动词是过去各种时态,则用It was… that(who)…。
注意点
①在强调主语时,that后的谓语动词要与被强调者保持人称和数的
It is I who am a teacher.
②即使被强调的主语是复数,主句中的谓语动词也用单数
It is they who often help me with my lessons.
③在强调时间、地点、原因、或方式状语时,不要用when,where,why
或 how ,而用that
It was because her mother was ill that she didn't go with us.
④在强调not … until 结构中由 until 短语(或从句)表示的时间状语时,
要用固定的强调句型
It is(was) not until ...that...。that 从句中的谓语动词用肯定式。
My father didn't come home until 12 o'clock last night.
It was not until 12 o'clock last night that my father came home.
⑤在强调一般疑问句中的某一成分时,主句要用一般疑问句的语序:
把is/ was提到it前面。
Did this happen in Beijing?
Was it in Beijing that this happened?
⑥特殊疑问句中只有疑问词可以强调,其强调结构是“被强调部分(通
常是疑问代词或疑问副词)+ is/was + it + that/ who + 其它部分?"
Where were you born?
Where was it that you were born?
⑦not …until…句型的强调句[来源:学|科|网Z|X|X|K]
句型为:It is/ was not until + 被强调部分 + that + 其它部分
原始句:He didn’t go to bed until/ till his wife came back.
强调句:It was not until his wife came back that he went to bed.
此句型只用until,不用till。但如果不是强调句型,till, until可通
用;因为句型中It is/ was not … 已经是否定句了,that后面的从句
要用肯定句,切勿再用否定句了。
谓语动词的强调
It is/ was … that …结构不能强调谓语,如果需要强调谓语时,用助动词do/ does或did。
Do sit down. 务必请坐。
He did write to you last week.上周他确实给你写了信。
Do be careful when you cross the street.
过马路时,务必(千万)要小心啊!
此种强调只用do/does和did ,没有别的形式;过去时用did,后面的谓语动词用原形。
