1． it is (was) + 被強(qiáng)調(diào)部分＋that (who)句中其他部分
強(qiáng)調(diào)結(jié)構(gòu)為：It is (was)…that…。它可以用來(lái)強(qiáng)調(diào)句中的某些成分，如主語(yǔ)（從句）、賓語(yǔ)（從句）、狀語(yǔ)（從句）等。如強(qiáng)調(diào)主語(yǔ)或賓語(yǔ)，則that可用who（指人），whom或which（指物）來(lái)代替；如強(qiáng)調(diào)的是狀語(yǔ)，則不能用when, where等代替，只能用that。注意，強(qiáng)調(diào)結(jié)構(gòu)不能用來(lái)強(qiáng)調(diào)謂語(yǔ)動(dòng)詞和表語(yǔ)。例如：
It was my uncle that (who) sent me the parcel.
It is the article that (which) they discussed last week.
It was because he was too careless that he broke all the glasses.
It is in this room that I was born 30 years ago.
2．謂語(yǔ)動(dòng)詞前用do，does，did表示強(qiáng)調(diào)
在肯定句中，可以用do強(qiáng)調(diào)謂語(yǔ)部分，可譯為：“務(wù)必”、“一定”、“真的”、“確實(shí)”等。這時(shí)動(dòng)詞要用原形。例如：
He does like to eat noodles.
She did send me a postcard as I expected.
3． “特殊疑問(wèn)詞+ is (was) + it + that + 句子”結(jié)構(gòu)
該結(jié)構(gòu)也起強(qiáng)調(diào)作用，表示“究竟在哪里”、“到底是誰(shuí)”等。例如：
Where was it (that) you saw the man?
你到底在哪里看見(jiàn)那個(gè)人的？
How is it (that) your answer differs from his?
你的答案怎么與他的不同？
