that if是什么意思

that if是什么意思
【问题实例】
有这样一个句子,有同学问,其中的that if 是什么意思:
You will let your friend borrow it, but tell him / her that if the camera is broken again, he / she will have to pay to get it repaired. 你会把照相机借给朋友,但是告诉他(她),如果这次再摔坏,他(她)得自己掏钱去修。

【问题分析】
有时that可以与if搭配使用,构成that if这样的形式,这样用时,其中的that 通常用于引导名词性从句(如宾语从句),而其中的if则用于引导条件状语从句。

如:
He said that if I had time I was to wash the floor. 他说如果我有时间的话就擦一擦地板。

He said that if his children were older he would emigrate.
他说如果他的孩子们再大点的话他就会移居国外。

他说,如果他在开车时打瞌睡,她必须把他叫醒。

He said that if he caught the plane he would be home by five.
他说他如果能赶上那班飞机,5点钟以前就可以到家了。

【句型变换】
这类句子通常可以将if 引导的条件从句移至句末而意思不变。

如:
He said that if he had a permit he could get a job.=He said that he could get a job if he had a permit. 他说如果他有许可证就能找到工作。

He said that if the floods got worse they would have to leave the house.=He said that they would have to leave the house if the floods got worse 他说如果洪水涨得更高,他们就得离开那所房子。

Tom said that if she wanted to stay on she would have to work harder. =Tom said that she would have to work harder if she wanted to stay on. 汤姆说她如果想继续留在那儿,就必须更努力地工作。

He was sure that if he drank any more of this good red wine he would fall asleep.=He was sure that he would fall asleep if he drank any more of this good red wine.

02 宾语从句-中考英语总复习 重点语法精讲精练(全国通用)

宾语从句一.宾语从句的定义(三分类)宾语从句是指在复合句中充当宾语的句子。

简单来讲,就是用一个句子充当了另一个句子的宾语。

在英语中我们常说动宾,介宾,即动词,介词后面所跟的成分可称之为宾语,当这个宾语由句子充当时即称之为宾语从句。

注: 宾语从句的分类1. 动词宾语从句:位于动词后面的宾语从句。

如:He asked whose handwriting was the best in our class.2. 介词宾语从句:位于介词后面的宾语从句。

如:I agree with what you said just now.3. 形容词宾语从句:位于形容词后面的宾语从句。

如:I’m glad that you can come. (在初中英语学习中,形容词宾语从句更多可以理解为固定搭配,如be glad/happy/sorry/sad/excited that +宾从,可总结为be+形容人心情的形容词+that +宾从)二.宾语从句的三种连接词(1)that:从句为陈述句语气时使用。

that无实际含义,在口语或非正式语体中可以省略He told me that his father was a doctor.注意:①动词宾语从句that可省略,介词宾语从句that不能省略①当一个句子中有两个或多个并列的宾语从句时,引导第二个和以后几个从句的that 不可省略。

即同一个动词后面同时跟了两个或多个that引导的宾语从句,第一个that可以省略,后面的that不能省略。

He told me (that) he had to leave and that he would be back soon.①注意it做形式宾语,that引导真正的宾语从句的情况,此时that一般也不能省略。

常见句型:make/think/find/suppose/imagine it adj that +宾从He has made it clear that he will not give in. 他不会屈服的,这一点他已经明确表示了。
