本單元的語法點(diǎn)是it引導(dǎo)的強(qiáng)調(diào)句。it可以用來對句子的某一成分進(jìn)行強(qiáng)調(diào)，其基本句型結(jié)構(gòu)為“Itis/was＋被強(qiáng)調(diào)的成分＋that/who/whom＋其他成分”。該結(jié)構(gòu)的強(qiáng)調(diào)成分僅限于主語、賓語和狀語。1．強(qiáng)調(diào)主語ItwasIthat/whometJackonthewaytoschoolthismorning.是我今天早晨在上學(xué)的路上碰到了杰克。2．強(qiáng)調(diào)賓語或介賓ItisMarywho/whom/thatyoushouldask.你應(yīng)該問的是瑪麗。Itwastomethatshegavethemoney.她那錢是給我的。3．強(qiáng)調(diào)狀語(1)強(qiáng)調(diào)地點(diǎn)狀語ItwasinShanghaithatIstudiedfouryearsago.我四年前就是在上海讀書。(2)強(qiáng)調(diào)時間狀語ItwasfouryearsagothatIstudiedinShanghai.就在四年前我在上海讀書。(3)強(qiáng)調(diào)方式狀語Itwasinthiswaythattheywonthegame.就是用這種方法他們贏得了比賽。注意：

(1)強(qiáng)調(diào)人時，連接詞可用that，也可用who(作從句的主語)或whom(作從句的賓語)；強(qiáng)調(diào)物或狀語時，連接詞只能用that。

(2)原句的謂語動詞時態(tài)是過去時，用“Itwas...”，其余用“Itis...”。如：ItisEnglishthatMr.Wangteachesus.王老師教我們的是英語。ItwasEnglishthatMr.Wangtaughtuslastyear.王老師去年教我們的是英語。(3)從結(jié)構(gòu)上看，把強(qiáng)調(diào)句的結(jié)構(gòu)去掉，剩下的仍是完整的句子。

(4)強(qiáng)調(diào)句的一般疑問句為“Is/Wasit...that...”；否定句為“Itisn't/wasn't...that...”；特殊疑問句為“特殊疑問詞＋is/was＋it＋that...”。如：Isittomorrowthatwewillhaveameeting?是不是明天我們將有一個會議？Itisn'ttomorrowbutthedayaftertomorrowthatwewillhaveameeting.不是明天而是后天我們將有一個會議。Whenwasitthatyoucaughtacold?你究竟是什么時候感冒的？一、完成句子
