1、Unit 3:Could you please tell mewhere the restrooms are?第三單元的語法重點是:賓語從句;語態(tài);倒裝句;程度副詞。賓語從句連接代詞和連接副詞引導的賓語從句。1. 由連接代詞 who, whom, whose, what, which 等引導,不能省略。例如:Do you know who he is?2. 由連接副詞 how, where, when, why 引導, 也不可省略。例如:I dont know where I can buy this kind of camera.3. 賓語從句用陳述句語序,即:連接詞 + 主語 + 謂語 +
2、 其他。4. 主句與從句的時態(tài)關系:(1) 如果主句是一般現(xiàn)在時,從句可以是根據(jù)情況所需要的任何時態(tài)。例如:I dont know when she came here.Can you tell me when he will come here?(2) 如果主句是過去的時態(tài),從句也應用過去時態(tài)的某一種。但若從句是表示客觀事實或真理時,從句時態(tài)不受主句時態(tài)的限制,應用一般現(xiàn)在時。例如:He told us why he would stay at home the next day.The teacher explained how the earth goes around the sun.
3、5. 某些由連接代詞或連接副詞引導的賓語從句可改為含“特殊疑問詞 + 動詞不定式”結構的簡單句。例如:Can you tell me where I can buy this book? Can you tell me where to buy this book?直擊中考1.【2017南昆明】33.Could you please tell me _ ?一The people and the food.A.how does Tom like ChinaB.if Tom likes ChinaC.what does Tom like about ChinaD.what Tom likes ab

5、則與 be 作為連系動詞時完全一樣。 被動語態(tài)的用法當我們不知道誰是動作的執(zhí)行者,或者沒有必要指出誰是動作的執(zhí)行者,或者只需強調(diào)動作的承受者時,用被動語態(tài)。倒裝句由so+助動詞(be/do/will/have)情態(tài)動詞+主語意為:也是一樣例如:She is a student.So am I.她是一個學生,我也是。She went to school just now.So did I. 她剛才去學校了,我也是She has finished the work.So have I. 她已經(jīng)完成了工作,我也完成了。She will go to school.So will he. 她將去學校,他也是。程度副詞程度副詞:always 總是usually 經(jīng)常sometimes有時never 從不如:I am always/usually/sometimes/never late for school.我總是經(jīng)常/有時/從不上學遲到。
