主要是宾语从句和状语从句,如果说考的稍微难一些的话就是定语从句以及名词性从句,一般考的话后两者的难度不会很大.宾语从句在句中作及物动词或介词的宾语,从句放在主袭磨数句之后,前后不用逗号分开.宾语从句：引导宾语从句的词有：连词that(在口语中that常可省略),if,whether,如：He knows that Jim will work hard.连接代词who,whom,which等,如：Do you know who (whom) they are waiting for?连接副词when,where,how,why等,如：Could you tell me how we can get to the station?3.whether和if都有“游亏是否”的意思,一般情况下两者可以换用,但在介词之后,不定式之前,与or not连用,在拍首句首或在引导表语从句,同位语从句时,只能用whether,如：I want to know if/whether the news is true.He doesn't know whether to stay or not?4.宾语从句要用陈述句语序.5.宾语从句一定要注意时态呼应,即：当主句谓语动词是过去式时,从句中谓语动词也要用过去范畴的时态,但若从句陈述的是真理或客观规律,其谓语的时态仍用一般现在时,如：He asked who could answer the question.My father told me that the earth goes around the sun.
