  一、主語從句
  1. 主語從句必須有引導詞,如果主語從句中從句表陳述,則一定用that引導。這里that無實際意義,類似于古代漢語中的“之”用來取消句子獨立性。如:That he was late made me angry.
  2. 當主語從句表示不確定的“是否”選擇關系時,則只能用whether引導而不用if。如:
  Whether he will go abroad is not decided yet!
  3. 當主語從句表示疑問時,用相應的疑問句加陳述句加陳述語序的句式,此時絕不能再加that.如:When he will come here will be announced in 20 minutes.
  二、賓語從句
  1. 當主句謂語動詞為think, suppose, expect, believe, imagine, guess等詞時,如果賓語從句是否定含義,則否定前移。如:I don’t believe he is a thief. 而不能說成I believe he is not a thief.
  2. 在含賓語從句的復合句中,如果就賓語從句中的成分提問、疑問句放在主句前(know做主句謂語動詞時除外),主句變疑問語序,而賓語從句仍用陳述語序。如:
  When do you think they should put their bikes
  Do you know where they should put their bikes
  3. whether 與if 的區別
 ?。?) 引導讓步狀語時只用whether.如:Whether it rains or not, you must go to school.
 ?。?)表語從句或同謂語從句中只能用whether
  如:The problem whether he will be killed will be discussed.
 ?。?) 與不定式或or not 連用時,應用whether引導。如:I don’t know whether to do it or not.
  三、幾組重要的連接成分
  1. who/whoever, what/whatever的區別
  一般說來,what/who 含特指意義,意為“什么/誰;而whatever/whoever含泛指意義,意為”無論什么/無論誰“。如:It is generally considered unwise to give a child _____ he or she wants.
  A. however   B. whatever    C. whichever   D. whenever
  2. where, when, why等連接副詞引導的名詞性從句。
  where., when, why 等連接副詞也可以引導名詞性從句,使用的關鍵是:這個詞必須符合句子的邏輯要求。如:
  --I drove to Zhuhai for the air show last week
  --Is that ______ you had a few days off
  3.”介詞+who(m)”引導的賓語從句與”介詞+whom”引導的定語從句的區別。
  介詞后面的引導詞用主格還是賓格,決定于它在賓語從句中作主語還是賓語。如:
  It was a matter of _______ would take the position.
  四、名詞性從句中的插入成分
  此時應注意兩點:一是從句仍然不倒裝,而在插入成分上倒裝;二是要注意主語的主格和賓格的選擇。如:
  _____ you have seen both fighters, ______ will win
  A. Since, do you think who B. As, who you think
  C. When, whoever              D. Since, who do you think
  五、引導詞that的省略
  引導賓語從句時,that可以省略,但引導主語、表語和同位語從句時,that不能省。
  China’s success in manned-spacecraft travel shows ______ our country has become one of the greatest powers in space research.
  A.what   B. which    C. /     D. it that
  六、同位語從句引導詞where、when的用法
  說明先行詞內容的同位語從句的引導詞where、when與被說明的名詞在概念上不一致。但引導定語從句的引導詞卻必須保持一致。試比較:
  1.They arose the question______ we were to get so much money.
  2.This is the house ________ the great man Mao Zedong was born 110 years ago.
  A. where    B. that    C. about which    D. in which
  1. I remember _____ the factory owned a small workshop and 2 machines.
  A. when  B. how   C. whether  D. what
  2. He always thinks of ______ he  can do more for the people.
  A. what   B. how  C. if     D. whatever
  3. What the doctors really doubt is _____ my mother will recover from the serious illness soon.

  5. After _____ seemed an endless effort, the patient was finally able to carry out _____seemed a perfectly normal walk.
  A. what; what   B. that; that    C. it; that   D. which; like
  答案:1. A   2. B  3. C   4. C  5. A
