3.whether和if都有“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，
3) It + be +过去分词+从句 It is said that... 据说…… It is known to all that...
