高中英语强调句课件
导语：高中英语强调句课件怎么写?以下是小编精心为大家整理的有关高中英语强调句课件，希望对大家有所帮助，欢迎阅读
基本结构：
It is (was)+被强调部分+ that (who)+句子其他部分。此结构强调的成分仅限于主语、宾语和状语。
例如：
It is not only blind men who make such stupid mistakes.
It was the goat’s eyes that he had seen in the darkness.
It is from the sun that we get light and heat.
It was not until I had read your letter that I understood the true state of affairs.
下面给出一个句子，根据强调的内容不同，做出的不同形式的强调句：
原句：My father did the experiment in the lab yesterday evening.
强调主语：It was my father who did the experiment in the lab yesterday evening.
强调宾语：It was the experiment that my father did in the lab yesterday evening.
强调时间：It was yesterday evening that my father did the experiment in the lab. (注意不用when)
强调地点：It was in the lab that my father did the experiment yesterday evening.
有几个方面是必须注意的：
1.条件，让步状语从句不能用强调句型改写，例如：
If it rains, we won’t go out. 如果下雨，我们就不出去。
We’ll try to finish the work in time though we are short of man power. 尽管我们人手不够，我们也会尽力按时完成工作。
2.It-type强调句可强调because引导的原因状语从句，但不可强调as, since引导的原因状语从句，例如：
I do it because I like it.因为我喜欢，我才干。可强调为：It is because I like it that I do it.
下面这个句子则不可以强调：
Since no one is against it, we’ll adopt the proposal.
3.It-type强调句可强调so that引起的目的状语从句，但不能强调so that 引起的结果状语从句，例如：
The six blind men asked the driver to stop the beast so that they could have a "look". 六个盲人要求赶象人让这头巨兽停下来，以便他们能“看一看”。可强调为：It was so that they could have a "look" that the six blind men asked the driver to stop the beast.
下面这个句子则不可以强调：
He didn’t plan his time well, so that he didn’t finish the work in time.
4.对由until引起的短语或从句强调，要注意否定前移，例如：
I didn’t learn it until yesterday.写成强调句型是：It was not until yesterday that I learned it.
He didn’t come back until his wife fell asleep. 写成强调句型是：It was not until his wife fell asleep that he came back.
5.在中学英语课本中还多次出现“What…be…”结构的句型（简称wh-type强调句），它同样具有很浓的强调意味，例如：
What we need is more time.我们需要的是更多的时间。
我们可以用对待It-type强调句的'方法，把“What…be…”作为一个框架而划去，所剩的也是一个完整的句子：We need more time.不同的是，what和be在句子中都可以担任成份。上面这个句子可以看成是 What引导一个主语从句，而be则 是系动词，后接表语。
（1）Wh-type强调句可用来强调主语、宾语、表语，例如：
But what surprised me most was to see some of the village people seated on the benches at the end of the room.
But what he was really interested in was beautiful paintings.
What I feel is hungry.
（2）wh-type强调句还可以通过使用动词不定式或动词-ing形式来强调句中的谓语动词或作宾语补足语的非谓语动词，例如：
What I did was (to) turn off the tap.
What I want you to do is (to) clean the room.
What I’m doing is teaching him a lesson.
（3）Wh-type强调句中的what从句，间或也作表语，例如：
This was what they had posted on the bulletin board then! This was what the black smith was reading! 原来贴在布告牌上的就是这么回事！铁匠在看的原来就是这个！
（4）Wh-type强调句的wh-从句，有时可能是以who, where或when引导，它们通常只用作表语，例如：
The headmaster was who I meant. 我指的就是校长。
Here is where the accident took place. 这儿就是事故发生的地方。
(On) Saturday is when the housewives are busiest. 星期六是家庭主妇们最忙的日子。
