新目標(biāo)英語九年級(jí)Unit 3 語法講解

Unit 3：Could you please tell mewhere the restrooms are?第三單元的語法重點(diǎn)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(dǎo)的賓語從句。1. 由連接代詞 who, whom, whose, what, which 等引導(dǎo)，不能省略。例如：Do you know who he is?2. 由連接副詞 how, where, when, why 引導(dǎo)， 也不可省略。例如：I don't 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 + 其他。4. 主句與從句的時(shí)態(tài)關(guān)系：(1) 如果主句是一般現(xiàn)在時(shí)，從句可以是根據(jù)情況所需要的任何時(shí)態(tài)。例如：I don't know when she came here. Can you tell me when he will come here?(2) 如果主句是過去的時(shí)態(tài)，從句也應(yīng)用過去時(shí)態(tài)的某一種。但若從句是表示客觀事實(shí)或真理時(shí)，從句時(shí)態(tài)不受主句時(shí)態(tài)的限制，應(yīng)用一般現(xiàn)在時(shí)。例如：He told us why he would stay at home the next day.The teacher explained how the earth goes around the sun.5. 某些由連接代詞或連接副詞引導(dǎo)的賓語從句可改為含“特殊疑問詞 + 動(dòng)詞不定式”結(jié)構(gòu)的簡(jiǎn)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 China B.if Tom likes ChinaC.what does Tom like about ChinaD.what Tom likes about China2.【2017廣西貴港】44.Could you tell me _ ?Sure.A story book.A.when did your friend give it to youB.what did your friend give youC.how your friend got to the supermarketD.what your friend gave you語態(tài) 英語有兩種語態(tài)：主動(dòng)語態(tài)和被動(dòng)語態(tài)主動(dòng)語態(tài)表示主語是動(dòng)作的執(zhí)行者被動(dòng)語態(tài)表示主語是動(dòng)作的承受者 被動(dòng)語態(tài)的構(gòu)成由“助動(dòng)詞 be+及物動(dòng)詞的過去分詞”構(gòu)成助動(dòng)詞 be 有人稱、數(shù)和時(shí)態(tài)的變化，其變化規(guī)則與 be 作為連系動(dòng)詞時(shí)完全一樣。 被動(dòng)語態(tài)的用法當(dāng)我們不知道誰是動(dòng)作的執(zhí)行者，或者沒有必要指出誰是動(dòng)作的執(zhí)行者，或者只需強(qiáng)調(diào)動(dòng)作的承受者時(shí)，用被動(dòng)語態(tài)。倒裝句由 so+助動(dòng)詞（be/do/will/have)情態(tài)動(dòng)詞+主語 意為：也是一樣例如：She is a student.So am I. 她是一個(gè)學(xué)生，我也是。She went to school just now.So did I. 她剛才去學(xué)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(xué)校，他也是。程度副詞程度副詞：always 總是usually 經(jīng)常 sometimes 有時(shí)never 從不如：I am always/usually/sometimes/never late for school.我總是經(jīng)常/有時(shí)/從不上學(xué)遲到。
