He wanted to stay at home. He said (that) he wanted to stay at home.

8、She doesn' t know. She is seriously ill. Shedoesn' t knowI am sure . He w川 succeed. I am sure .2) .賓語從句原先是特殊疑問句的，由其本身疑問詞連接。連接代詞who, whom, whose, what, which 和連接副詞 when, where, why, how 。這些連接代詞和連接副詞在賓語從句中充當(dāng)某個成分。例如：Do you know ? Who (whom) are they waiting for?Do you know who (whom) they are w

9、aiting for?I don ' t know.Can you tell me? Where is the No.3 bus stop ? Why is the train late?3) .賓語從句原先是一般疑問句的，由if或whether 0 If和whether在句中的意思是“是否”。I want to know. Does he live there?I want to know if he lives there?He asked me. Was there a book store on Center Street? 2 .賓語從句的語序賓語從句的語序應(yīng)為陳述句(主謂式

10、)的語序。例如：I hear (that) physics isn ' t easy.I think (that) you will like this school soon. Can you tell me how Ican get to zoo?Please tell me when we ' ll have the meeting.3 .賓語從句的時態(tài)1）如果主句的時態(tài)是一般現(xiàn)在時，賓語從句該用什么時態(tài)就用什么時態(tài)。如：I don' t think （that） you are right. Please tell us where he is.Can you

11、tell me how I can get to the railway station?2）如果主句的時態(tài)是一般過去時，賓語從句只能用相應(yīng)過去時態(tài)（一般過去時，過去進(jìn)行時， 過去將來時，過去完成時）。例如：He asked what time it was.He told me that he was preparing for the sports meet.He asked if you had written to Peter.He said that he would go back to the U.S. soon.3）如果賓語從句所陳述的是客觀真理，其時態(tài)常用一般現(xiàn)在時。例Our

12、 teacher said that January is the first month of the year.Scientists have proved that the earth turns around the sun.賓語從句的口訣：學(xué)習(xí)賓從要注意，時態(tài)語序和連詞。時態(tài)主從要呼應(yīng)：主句若為現(xiàn)在時，從句時態(tài)隨句意。主句若為過去時，從句時態(tài)變過去。賓從所示表真理，時態(tài)不變不懷疑。語序要用陳述序，切莫照搬疑問句。 That連接陳述句，省與不省要注意。 從句若表”是 否”時，if/whether 要牢記。 特殊問句做賓語，仍用原來疑問詞。 三個問題要記牢，切 莫丟東又往西。（ ）1.

14、on the weather.A.If B.Whether C.That D.Where學(xué)習(xí)賓語從句要抓住三要素：連接詞、語序和時態(tài)。1.引導(dǎo)詞1 .從句為陳述句，常選擇引導(dǎo)詞that或?qū)hat省略，直接與主句相連。2 .從句為一般疑問句，常選擇if或whether。在whetheror not 結(jié)構(gòu)中不能用if 替 換。3 .從句為特殊疑問句，常選擇 what, when, where, which, who, how等的疑問代、副詞作引導(dǎo)詞。注意：當(dāng)who為主語時，句式為：who+胃語+其他4 .判斷時態(tài)情況1 .主句是一般現(xiàn)在時，從句為各種時態(tài)情況。2 .主句是一般過去時，從句為各種相

15、應(yīng)過去時態(tài)注意；描繪客觀事實(shí)，用一般現(xiàn)在時。()1. The teacher told the children that the sun round. A. was B. isC. were D. are( )2. I believe that our team the basketball match.

54、six years old; She didn't hear of you before.2）疑問句（一般、特殊、選擇、反意）：Do they like skating? Howold is he? Is he six or seven years old?

55、but, or 等）或分號（；）把兩個或兩個以上的簡單句連在起構(gòu)成。 You help him and he helps you.3）復(fù)合句：含有一個或一個以上從句的句子。復(fù)合句包含：名詞性從句（主語從句、賓語 從句、表語從句和同位語從句）、定語從句和狀語從句等。（二）簡單句的五種基本句型1、主語 +系動詞 + 表語：e.g. He is a student.2、主語+不及物動詞：e.g. We work.3、主語 + 及物動詞 + 賓語：e.g. Henry bought a dictionary.4、主語+及物動詞+雙賓語（間接賓語+直接賓語）：e.g. My father bought

Don ' t do it like that,?3、對簡單句、并列句和各種復(fù)合句的考查常表現(xiàn)在對連詞的選擇和使用上。如：and, but,or, while ,以及其它連接名詞性從句、定語
