在各种从句中,什么情况下THAT可省大神们帮帮忙

使用宾语从句应注意的问题 使用宾语从句应注意的问题 1.引导词that的省略.在非正式场合下,that在引导宾语从句时可以省略.例如:I think (that) you are right.He said (that) he would come.但在正式场合,特别是表示建议要求的从句,一般不省略.2.关于使用形式宾语"it"的问题.如果宾语从句后面跟有宾语,要用形式宾语"it"来代替,而将从句放到补语的后面去.如:I heard it said that this school was founded in 1906.3.宾语从句的时态呼应.如果主句的谓语是过去时,宾语从句的时态要按照时态呼应规则进行相应的调整.但若宾语从句表示的是客观真理或自然观念,其谓语时态则仍然一般现在时.如:She said she had left her umbrella in the classroom.The teacher told us that the Pacific Ocean is the largest ocean in the world.4.宾语从句否定意义的转移.在think,believe,suppose等动词所跟的宾语中,如果从句谓语是否定的,一般要将否定词not转移至主句谓语上去,而将从句谓语改为肯定形式.如:I don't think he has time to play with you.5.插入语疑问句.当我们要对宾语从句的有关信息进行提问时,通常要用"插入语疑问句".该结构以与所询问信息有关的疑问词开头,主句的主谓成份变成插入语.例如:They said that they had cleaned the classroom.What did they say they had done?6.宾语从句的替代.在hope,believe,imagine,suppose,guess,think等动词以及"I'm afraid"等表达法的后面,可有so代替一个宾语从句,该宾语从句通常是上文提到的一件事.如:Do you think we will have good weather?I hope so.其否定形式可用上述动词的否定式(hope除外),或者用"not"代替"so".如:I don't believe so.(或I believe not.)
