英语四级语法:强调句详解
想要学好英语四级语法怎么能不知道强调句的用法呢?下面就让小编为大家详解一下吧。
强调句通常用的句式:it is + 被强调的部分 + that + 句子的其余成分。强调部分指人的时候,用who 或者that; 指物的时候用that。
例1:
It is from the sun that we get light and heat.
被强调的部分(物)
例2:
It was Sam who knocked down that old man and fled.
被强调的部分(人)
注意:如何判断强调句式?
把一个句子中的it is …that/who这个部分去掉,如果剩余的句子仍然是完整的,那么这个句式就是一个强调句。反之则有可能是其他从句。
例如:
It is exciting that we succeeded in launching the satellite.
这个句子虽然也有it is … 的`结构,但只要把这个结构去掉,就可以发现:剩下的内容不能构成完整的句子。所以这不是一个强调句。在这里It is…that 是不能随便去掉的,因为这里it 是形式主语。
翻译示例:
例:______________ (直到他详细研究)that the first of the vitamins was identified.
1. 所译部分为句子的主干,需要强调句型,表达方式为it is not
2. 从句为过去时,所以主句中也应该是过去时
3. “详细地”表达方式应该是in detail。
答案:It was not until he investigated in detail

答案及解析:
1. C 2. B 3. B 4. D 5. C 6. D 7. D 8. D 9. D 10. B
1. 本题考查的是强调句式。强调句式由“it is/was + 被强调成分+that/who…”构成。此题强调的是时间。
2. 在谓语动词前加do表示对动作的强调。and连接两个并列谓语,其形式应一致,故用过去时态。
3. 此题考查的是强调句的特殊疑问句形式。it在此作为形式主语,真正的主语是that从句。
4. 此句是一个强调句。根据题意“他的朋友不怎么喜欢看电视”可知这并没有什么可奇怪的,故排除B和C。no后直接加名词相当于not any +名词,可排除A。故选D。
5. 此题考查的强调句中含有一个定语从句。Who引导的定语从句修饰被强调部分the boy,that引导的从句构成强调句中的真正的主语。当被强调部分是人时,可以用that和who来引导从句。
6. 此题考查的强调句型中包含一个定语从句。Which引导的定语从句,修饰被强调部分the training,that从句构成强调句中的真正主语。
7. 本题考查的是强调句式。强调句式由“it was + 被强调成分+ who…”构成。
8. 本题考查的是强调句式。强调句式由“it was + 被强调成分+that…”构成。本句强调的是时间。
9. 本题考查的是强调句式。强调句式由“it was + 被强调成分+that…”构成。本句强调的是时间。not until…意为“直到……才”。
10. 本题考查的是强调句式。强调句式由“it was + 被强调成分+that…”构成。从句的语序仍然用陈述语序。
