一、主语从句
　　1. 主语从句需有牵引和帮助词，如若主语从句中从句表申辩权，则固定用that牵引和帮助。这里英文that无现实现实意义，相仿于汉代对外汉语中的“之”可以更改话语独有性。如：That he was late made me angry.
　　2. 当主语从句数字代表不确实的“是”采用直接关系时，则会用whether牵引而不一样if。如：
　　Whether he will go abroad is not decided yet！
　　3. 当主语从句说明问题解答时，用合理的问题解答句加诉说句加诉说语序的句式，这时从没能再加上that.如：When he will come here will be announced in 20 minutes.
　　二、宾语从句
　　1. 当主句谓语动名词为think, suppose, expect, believe, imagine, guess等词时，如果你宾语从句可疑问句型号规格说明，则疑问句上移。如：I don’t believe he is a thief. 而没办法当做I believe he is not a thief.
　　2. 在含宾语从句的组合句中,要是就宾语从句中的化学成分提出问题、疑义句放着主句前（know担任句谓语动名词时以外），主句变疑义语序，而宾语从句仍用法庭辩论语序。如：
　　When do you think they should put their bikes
　　Do you know where they should put their bikes
　　3. whether 与if 的差别
　　（1） 修复系统妥协状语时仅需要用whether.如:Whether it rains or not, you must go to school.
　　（2）表语从句或同谓语从句中只可用whether
　　如：The problem whether he will be killed will be discussed.
　　（3） 与也不确定式或or not 用上时，应用领域whether引导和帮助。如：I don’t know whether to do it or not.
　　三、几组非常重要的连到含量
　　1. who/whoever, what/whatever的什么差别
　　平常说起来，what/who 含就是指价值，意为“是啥/谁；而whatever/whoever含就是指价值，意为”大多数是啥/大多数谁“。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等无线连接副词引领的形容词性从句。
　　where., when, why 等接触副词也能够指导名称性从句，采用的重要的是：该词必须要完全符合语段的结构请求。如：
　　--I drove to Zhuhai for the air show last week
　　--Is that ______ you had a few days off
　　3.”介词＋who（m）”加以视情况加以引导的宾语从句与”介词＋whom”加以视情况加以引导的定语从句的不同之处。
　　介词后的指导词用主格還是宾格，而定于它在宾语从句中作主语還是宾语。如：
　　It was a matter of _______ would take the position.
　　四、动词性从句中的放物质
　　在此应特别留意圆心：八是从句依旧不倒装，而在放进去组成成分上倒装；第二是要特别留意主语的主格和宾格的采用。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、视情况加以引导词that的省略
　　引流宾语从句时，that可不可以省略，但引流主语、表语和同位语从句时,that不能少。
　　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、同位语从句疏导词where、when的用途
　　表明优先词内部的同位语从句的正确诱导词where、when与被表明的词在理念上不不对。但正确诱导定语从句的正确诱导词却需增加不对。试非常：
　　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

　　4. Some college students are seen doing _____ work they can find to support themselves.
　　A. that    B. which   C. whatever   D. no matter what
　　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
　　结果：1. A   2. B  3. C   4. C  5. A
