　　?？嫉膹?qiáng)調(diào)句結(jié)構(gòu)是it 引導(dǎo)的句子。

　　It is (was) 被強(qiáng)調(diào)部分+ that (who) + 句子其他部分。

　　此結(jié)構(gòu)強(qiáng)調(diào)的成分僅限于主語(yǔ)，賓語(yǔ)和狀語(yǔ)。

　　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.

　　典型例題

　　1) It was last night ___ I see the comet.

　　A.　the time　B.　when　 C.　that　　D.　which

　　答案C. 強(qiáng)調(diào)句的結(jié)構(gòu)是： It +be +強(qiáng)調(diào)部分 + that (who) + 主謂句?！?qiáng)調(diào)句的連詞只有兩個(gè)，that和who。當(dāng)強(qiáng)調(diào)的部分是人，且為句子的主語(yǔ)時(shí)，才用 "who"，其余用that。

　　原句：　My father did the experiment in the lab yesterday evening.

　　強(qiáng)調(diào)主語(yǔ)： It was my father who did the experiment in the lab yesterday evening.

　　強(qiáng)調(diào)賓語(yǔ)： It was the experiment that my father did in the lab yesterday evening.

　　強(qiáng)調(diào)時(shí)間： It was yesterday evening that my father did the experiment in the lab. (注意不用when)

　　強(qiáng)調(diào)地點(diǎn)： It was in the lab that my father did the experiment yesterday evening.

　　2)It is ten years ___ Miss Green returned to Canada.

　　A. that　B. when　 C. since　 D. as

　　答案C. 考點(diǎn)是連詞用法。 本題易誤選為A. that. 其實(shí)本句不是強(qiáng)調(diào)句。若是，去掉It　 be… that還應(yīng)是一個(gè)完整的句子。而本句去掉 It is…that，只剩下ten years Miss Green returned to Canada. 不成句。因此本句不是強(qiáng)調(diào)句。

　　It is /was +時(shí)間+ since…　其中is<---> has been　 was <---> had been.
