省略和强调句

省略和强调句

语法复习五:强调句、It的用法、省略和插入语一、强调句(一)强调句句型1、陈述句的强调句型:It is/ was + 被强调部分(通常是主语、宾语或状语)+ that/ who (当强调主语且主语指人)+ 其它部分。

e.g. It was yesterday that he met Li Ping.2、一般疑问句的强调句型:同上,只是把is/ was提到it前面。

e.g. Was it yesterday that he met Li Ping?3、特殊疑问句的强调句型: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?e.g. When and where was it that you were born?4、强调句例句:针对I met Li Ming at the railway station yesterday.句子进行强调。

强调主语:It was I that (who) met Li Ming at the railway station yesterday.强调宾语:It was Li Ming that I met at the railway station yesterday.强调地点状语:It was at the railway station that I met Li Ming yesterday.强调时间状语:It was yesterday that I met Li Ming at the railway station.5、注意:构成强调句的it本身没有词义;强调句中的连接词一般只用that, who,即使在强调时间状语和地点状语时也如此,that, who不可省略;强调句中的时态只用两种,一般现在时和一般过去时。

原句谓语动词是一般过去时、过去完成时和过去进行时,用It was … ,其余的时态用It is … 。

不定代词it的用法

不定代词it的用法

不定代词it的用法一、不定代词it的基本用法在英语中,不定代词it充当性别不明、指代某个特定事物或概念等的角色。

它是一个非常常用且灵活的代词,能够承担多种种类和功能。

在下面的段落中,我将会详细介绍it作为不定代词的几种常见用法。

1. 作为形式主语或形式宾语在很多情况下,人们使用it作为形式主语或形式宾语来引导句子。

这是因为句子的真正主语或宾语可能是一个复杂的短语或从句,而使用it可以把这个复杂结构移到句子后面而不影响主谓结构。

例如:- It is important to have a healthy diet.(拥有健康饮食习惯很重要。

)- I find it difficult to understand this concept.(我发现理解这个概念很困难。

)2. 作为反身代词当需要表示某人自己的行动时,人们通常会使用反身代词来强调动作涉及到了自己。

在没有特指具体人物时,可以使用it作为反身代词。

例如:- I really enjoyed the concert last night. It was a great experience!(我昨晚非常享受这场音乐会。

它是一次很棒的体验!)3. 引导形式主语从句或形式宾语从句在某些情况下,it作为形式主语从句或形式宾语从句的引导词,用来替代真正的主语或宾语,以使整个句子结构清晰明了。

例如:- It is believed that exercise can improve mental health.(人们认为运动可以改善心理健康。

)- I find it hard to believe that she won the lottery.(我发现难以相信她中了彩票。

)二、不定代词it的特殊用法除了上述基本用法外,不定代词it还有一些特殊的使用方式。

在接下来的几个段落中,我将逐一介绍这些特殊用法。

1. 强调句型当想要强调一个特定的信息时,可以使用强调句型来突出该信息,并且通常把被强调的部分放在it后面。

(全)新概念英语第二册语法详解:倒装句+定语从句+It的用法

(全)新概念英语第二册语法详解:倒装句+定语从句+It的用法

新概念英语第二册语法详解:倒装句+定语从句+It的用法倒装句知识要点:英语的基本语序是“主语+谓语”。

如果将谓语的全部或一部分放在主语之前,这种语序称为“倒装”。

一、倒装的类型1.完全倒装:整个谓语移至主语之前。

Out rushed the students to welcome the foreign friends.2.部分倒装:只把系动词,情态动词,助动词或表语放在主语之前。

Seldom does he go to school late.二、倒装结构的基本用法1、由于语法结构的需要而使用的倒装1) 疑问句中,用完全或部分倒装,但以疑问词或疑问词修饰的名词作主语的疑问句要用正常语序Where did he go last Monday?Are you listening to the radio?2) “there be”结构中,There are three wells in our village.There stands a big paper making factory by the river.3) 在以here, there, now, then, in, away, up down等副词开头的句子中,使用完全倒装结构。

但如果主语是代词则用正常语序。

There goes the bell.Now comes your turn to playDown she went.4) 在以neither nor 或no more开头的句子中,表示“……也不这样”,neither 和nor意思相同,可以替换使用;no more表示动作的程度并不比前面提到的稍强,意为“也不……”。

I can’t swim, nor (neither) can she .He hasn’t been to the countryside, neither does he want to go there. He did not turn up. No more did his wife.5) 用在as(尽管)引导的让步状语从句中,从属连句as用于特殊语序,含义与though, although相同,但“as”这种结构可表示非常强烈的对照,必须用倒装(表语提前)。

如:
If it hadn’t been for the freezing wind they could have reached the injured man in ti me. 要不是有刺骨的寒风,他们就及时赶到伤员身边了。

二、考查it 用作形式宾语的用法
当不定式、动名词、从句等用作宾语且其后跟有宾语补足语时,就应在宾语补足语前使用形式宾语,而将真正的宾语移至句末:
We found it difficult to persuade her. 我们发现很难说服她。

He makes it a rule to get up before dawn. 他习惯于天亮前起床。

I think it very strange that he goes out walking almost every night. 我认为他几乎每晚都出去散步是很奇怪的。

【特别提醒】注意it用作形式宾语的三类特殊句式:
1.动词+it+if / when从句
当enjoy, like, dislike, love, hate, prefer, appreciate等动词后需要接一个if或when引导的从句时,此时必须要先在动词后接it作形式宾语。

如:
She won’t like it if you arrive late. 她不喜欢你迟到。

He hates it when people use his bike. 他讨厌别人用他的自行车。

I’d prefer it if I didn’t have to do so much work. 要是我不必做那么多工作,那就太好了。

I would appreciate it very much if you would help me with it. 如果你能帮助我做这事,我会十分感激。

2.动词+介词+it+that从句
能用于此句型的主要有三个动词,即depend on, answer for, see to。

如:

I can’t answer for it that the boy is honest. 我不能保证这个男孩是诚实的。

I’ll see to it that all these letters will be sent to the post before twelve. 我将注意让所有的信件在12点以前送到邮局。

三、考查it 在强调句中的用法
强调句的基本结构是:It+be+被强调部分+that(who)+其他部分。

如:
It was yesterday that he got married. 他是昨天结婚的。

It was a computer that he bought last week. 他上个星期买的是一台电脑。

【特别提醒】对于强调句的复习要特别注意两种情形:
1.当强调句有插入语或复杂修饰语时:
It was lack of money, not of effort, that defeated their plan. 他们的计划受挫,原因是缺少钱而不是没有尽力。

It was more in sorrow than in anger that he criticized his former colleague. 他批评以前的同事,并非出于气愤而是为他惋惜。

2.当强调为特殊疑问句时:
Who was it that won the World Cup in 1982? 谁赢得了1982年的世界杯?
How long ago is it that you last saw her? 你上一次看见她是多久以前的事?
四、考查it 与one 的区别
两者均可代替前面提到的事物,区别是:it指的是与前面已提到的事物为同一物,此时的it等于“the (this, that, my...)+名词”;而one 指的是与前面已提到的事物为同一类物,此时的one等于“a+名词”。

比较():
I have a dictionary but I’ve lent it to Mary. 我有一本词典,但把它借给玛丽了。

I haven’t a dictionary; can you lend me one? 我没有词典,你能借我一本吗?
五、考查it 在习语中的用法
包括it的习语很多,比如make it就是其中很重要的一例。

如:You can make it if you hurry. 如果你赶快还可以及时赶到。

He wants to make it as a writer. 他想作一名作家而一举成名。

You needn’t worry; he will make it. 你不必担心,他会办成的。
