A.whether与if在引导名词性从句时的区别
1)主语从句、介词宾语从句只能用whether引导;
2)whether 0r not可以连在一起用,而if or not则不能,or not只能放在句末;
3)在question,ask后面一般只用whether,question的同位语从句也用whether;
4)后接不定式时,只能用whether。
B.what的用法;
C.whoever与whomever分别是主格与宾格。它们的出现取决于它们在从句中作主语还是作宾语;
D.宾语从句否定转移:动词believe,expect,fancy,imagine,suppose,think后的宾语从句如为否定式,一般将否定词转移到主句谓语上
