在中学english英语教学中,提到强调句型时,通常指的是:"It be…that…"这一结构(简称It-type强调句)。 这确实是一个非常有用的句型,在中学english英语课本中也多次出现,例如:

    It is not only blind men who make such stupid mistakes.(SBI,P28)
    决不只是盲人才犯这样愚蠢的错误。
    It was the goat's eyes that he had seen in the darkness.(SBI,P211)
    他在黑暗中看到的就是这只山羊的眼睛。

    It-type强调句的特征是:如果我们把"It be…that…"从句中划去,所剩的正好是一个完整的句子。例如 上面第一句经过处理后就成了:

    Not onlt blind men make such stupid mistakes.

    它的意思仍然是完整的,只是强调意味已经失去。实际上"It be…that…"只不过是一个框架而已,它的各 部份在句子中均不担任成份。

    It-type强调句通常可用来强调句子的主语、宾语、状语。但强调状语时,有几个方面是必须注意的:
    1.条件,让步状语从句不能强调,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 ofman power.
    虽然我们缺乏人力,我们还是要设法按时完成这项工作。

    不能强调为:

    It is if it rains that we won't go out.
    It is though we are short of manpower that we'll try to finish the work in time.

    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.
    既然没有人反对,这个议案我们就通过了。

    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 blindmen asked the driver to stop the be ast.
    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 thework in time.
    他没有把时间计划好,结果没有按时完成这项工作。

    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.
    直到昨天我才知道这件事。
