1.一般情況用It is(was)……that…,分別可以強(qiáng)調(diào)主語、賓語、地點(diǎn)狀語和時(shí)間狀語.如：
　　It was he who( that)read three books in the library yesterday.(強(qiáng)調(diào)主語)
　　It was three books that he read in the library yesterday.(強(qiáng)調(diào)賓語)
　　It was in the library that he read three books yesterday.(強(qiáng)調(diào)時(shí)間狀語)
　　2.當(dāng)被強(qiáng)調(diào)部分指人時(shí),可用that,也可用who；指物時(shí),只用that,如：
　　3.強(qiáng)調(diào)狀語時(shí),只用that,不用when、where.如：
　　4.被強(qiáng)調(diào)的部分是主語時(shí),注意句子的謂語動詞和被強(qiáng)調(diào)的主語保持一致.如：
　　It is he who is late.　It is they that were late.
　　5.一般疑問句的強(qiáng)調(diào)句為“Is (was) it that…?”；特殊疑問句為：“特殊疑問詞 is (was) that…?”結(jié)構(gòu).如：
　　Was it ten years ago that his father died?（他的父親是十年前去世的嗎?）
　　When is it that you will set off?（你到底什么時(shí)候出發(fā)?）
　　6.“not…until…”句型的強(qiáng)調(diào)結(jié)構(gòu)為“It is not until…that…”應(yīng)注意把否定詞not轉(zhuǎn)移到until前面.如：
　　I didn't go home until rain stopped.(直到雨停了我才回家).
　　強(qiáng)調(diào)句為：It was not until rain stopped that I went home.
　　強(qiáng)調(diào)句去掉It is.that ,還原一下次序,句子依舊完整.
