引导单个宾语从句时,that可以省略。
但引导主语从句、表语从句、同位语从句与形式宾语it并存的宾语从句时,that都不能省略。
如果引导两个或两个以上宾语从句,第一个that可以省略,从第二个宾语从句起向后的从句中的that不能省。
例如:1. I don’t think (that)she is coming. (可省)2. The reason is that he is careless. (不能省)3. The news that our team won the match inspired us.(不能省)4. I don’t think it necessary that you should read English aloud. (不能省)5. He told me (that)his father had died and that he had to live alone.(第一个可省,第二个不可省)②.从属连词whether 和ifWhether 和if 是“是否”的意思,在从句中不担当句子成分。
引导宾语从句时(动词后面的宾语从句)二者可以换用,若宾语从句提前只用whether. 但引导主语从句、表语从句、同位语从句、介词后的宾语从句,及紧跟or /or not 结构或不定式时,只能用whether.①He wants to know whether or not you agree.②He doesn’t know whether to stay or not.③He wondered whether to accept or refuse.④It all depends on whether they will do their best.⑤Whether she will come or not is still a question .⑥The question is whether it is worth doing.⑦None of them can answer the question whether it is worth doing.2 .连接代词:who , whom, what , which , whose 及whoever, whomever, whatever, whichever既保留原意,又在从句中担当句子成分。

本书根据最新资料不再作此分类,通称关系代词和关系副词。

(that在从句中只起引导词作用,不作成分)What caused the accidentis still a complete mystery. 事故发生的原因仍然是个不解之谜。
(What 在从句中作主语)2、that与whether引导名词性从句的区别。
that与whether都是连词,引导名词性从句时,在句中只起连接作用,都不担任句子成分,使用时有下列区别:(1)动词doubt表示“怀疑、不知道” 解时,肯定句接whether引导的宾语从句;否定句don’t doubt和疑问句Do you doubt要接that引导的从句。
I don’t doubt that he will come soon.我不怀疑他不久会来。
(此处不用whether)Can you doubt that he will win?你怀疑他会赢吗?(此处不用whether)I doubt whetherit is true.我怀疑那不是真的。
比较:doubt表示“不信”解时,表示强烈的不相信时,在陈述句中可接that从句。
I doubt that he will stay there.我不信他会留在那里。
(2)that本身无意义,有时可以省略;whether本身有意义,在句中均不可省略。
He said (that) he was from New York.他说他是从纽约来的。
(that无意义,可以省略)Whether he will go there is not decided yet.他去不去没定下来。
(whether 有意义,不可以省略)(3)如果宾语从句表示两种可能性据其一时,只能用whether(or not),不可用that。
I wonder whether he knew the manager(or not).我不知道他是否认识经理。
(不能用that)I am not surewhether he will come.他来不来我没把握。
(不能用that)(4)whether引导的从句能几乎作所有介词的宾语;that引导的从句只能作except, but, besides 的介词宾语。
I have no interest in whether he will come.我对他来与否不感兴趣。
(不能用that)He is a good boy except that he is careless sometimes.他是个好孩子,只是有时有点粗心。
3、whether和if的区别(1)whether可以引导discuss和介词宾语从句,而if不能。
I haven’t settled the question of whether I’ll lend him the money.我还没决定是否把钱借给她。
(不能用if)They are talking about whether they will go there.他们正在讨论是否去那里。
(不能用if)(2)whether可以应到所有的名词性从句,而if只能引导宾语从句;在引起主语从句时,特别是主语从句在句首时,不能用if,除非是有形式主语it的主语从句。
Whether the 2000 Olympic Games will be held in Beijingis not known yet. 2000年奥运会是否在北京举行还不知道。
(不能用if)Whether we'll go camping tomorrowdepends on the weather. The question is whether it is worth doing.问题是这值不值得做。
我们明天是否去野营要看天气而定。
(不能用if)The question whether we need it has not been decided.我们需不需要它还没定。
(不能用if)(3)whether后可以直接跟or not或or no,构成whether or not或whether or no,if则不能。
但可以说whether/if… or not, whether/if… or。
I don't know whether or not he'll come. 我不知道他是否会来。
(不能用if)He will leave for Paris tomorrow, whether or no.他明天无论如何要动身去巴黎了。
(不能用if)I don’t care whether/ if you come or not.我不关心你来与否。
(4)if 引导的从句可用于否定的谓语,whether引导的从句不用于否定的谓语。
I don't careif you won't come.我才不在乎他来不来呢。
He does n’t care if you don’t pay the money.你付不付钱他不在乎。
(5)whether …or可以引导让步状语从句,or不可省略;if可以引导条件状语从句。
Whether it snows or not, I will go there by bike.不论明天下不下雪,我都骑车去。
If he had been given more time, he could have done it much better. 如果给他更多的时间,他会做得更好。
(6)whether可以和不定式连用,而if不能。
He didn’t know whether to get married or to wait.他不知道是现在结婚还是等等再说。
They haven’t decided whether to go there or not.他们还没决定去不去。
(7)whether和if引导的宾语从句,可以用肯定,也可以用否定,但含义不同。
He asked whether she could help.他问她是否能帮忙。
(表示疑问,可加or not)He asked whether she couldn’t help.他认为她能帮忙。
(表示否定,不可加or not)巧记whether与if异同“whether”与“if”都可表“是否”,是常考内容。
下面的顺口溜可帮你记住其异同。
主从表从同位从,if不用whether用;discuss和介词后,whether引宾从;不定式、or not后面跟,whether独能显神通;宾从如是否定句,if发挥其功用;避免歧义要慎重,其它情况可换用。
4、关系代词与关系副词引起的名词性从句的应当注意的问题(1)wh-ever引起的名词性从句不含疑问意义,相当于不定代词后加一个定语从句:whatever = anything that,whoever=anyone who, wherever=any place where, whenever=any time when表示泛指;而what,which,who,when,where,how等词都有时含有疑问意义,表示特指。
A computer can only do what you have instructed it to do. 计算机只能按人们的指令去做事。
(特指)It is generally considered unwise to give a child whatever he or she wants. 普遍认为,孩子要什么就给他什么不是聪明之举。
(泛指)It was a matter of who would take the position. 问题是谁担当这个职位。
(特指)Whoever has helped to save the drowning girlis worth praising.不论谁救了这个溺水孩子都值得表扬。
(泛指)(2)介词后的who/whom,whoever/whomever的选择问题,则要看连接词在从句中是作主语还是作宾语而定,如在从句中作主语则只能选用who/whoever。
Give them to whoever is likely to be interested.把他们送给感兴趣的人。
(不能用whomever)Whodo you think is the best student?你认为谁是最好的学生。
(不能用whom)Sarah hopes to become a friend ofwhoever shares her interests.塞拉希望成为和她能同甘共苦的人的朋友。
(3)正确使用who/ whoever,what/whatever,how/however,where/wherever,when/whenever,which/whichever,who,what,where,when,how,which一要分析句子结构,看其在从句中作何成分,二是理清其在句中的含义。
