强调句
在英文中，句子的主语、宾语、状语都可以写进一定的句式里以表示对它的强调。
它们是:
1. It is / was + 被强调的部分 + that ( who, which ) + 句子的其他部分,
2. What … is / was …这种句式就称为强调句。
1. It is/was + 被强调的部分 + that(which) + 句子的其他部分
下面我们以两个句子为例来演示强调句的构成。如：
1)Western health-care system are spending
主语
huge sums of money on the surgical treatment
宾语 状语
of the disease.
西方国家医疗保健机构在心脏病的手术治疗上开支巨大。
强调主语
It is Western health-care system that are spending huge sums of money on the surgical treatment of the disease.
正是西方国家医疗保健机构，在心脏病的手术治疗上开支巨大。
强调宾语
It is huge sums of money that Western health-care system are spending on the surgical treatment of the disease.
西方国家医疗保健机构在心脏病的手术治疗上，开支确实是巨大的。
强调状语
It is on the surgical treatment of the disease that Western health-care system are spending huge sums of money .
西方国家医疗保健机构，就是在心脏病的手术治疗上付出了巨大的开支。
2)谓语动词的强调
do / does / did +动词原形强调。
例如：
我的确相信他是老实人。
I do believe that he is an honest man.
她确实喜欢文学。
She does like literature.
他们昨天的确去看过你，但没见到你。
They did go to see you yesterday, but failed to meet you.
4)What … is / was …
"What … is / was …"是名词从句结构，也是强调句的另一种构成形式。它常用来强调主语、宾语。如果所叙述的是现在或者将来发生的事情用"What is … that…"的句式;如果所叙述的是过去发生的事情用"What was … that…"的句式。
