ii.疑問詞 + ever和no matter + 疑問詞的區(qū)別：
①疑問詞 + ever可引導名詞性從句，在主從句中要充當一定的部分。
whoever breaks the rule must be punished.
you can choose whatever you like in the shop.
②疑問詞 + ever還可引導讓步狀語從句。如：
whoever breaks the rule, he must be punished.
whatever you do, you must do it well.
③no matter + 疑問詞只能引導讓步狀語從句。
no matter what you do, you must do it well.
no matter who breaks the rule, he must be punished.
iii.名詞性從句中的虛擬語氣問題：
1.在order、suggest、demand、request、advise、be anxious that等所接的賓語從句中用“should” 型虛擬語氣，“should” 常省略。 在order、suggestion等名詞后同位語從句、表語從句中用“should ”型虛擬語氣，可省略“should”.
2.在as if、as though引導的表語從句中，在必要的情況下應用過去式虛擬語氣。
3.在suggest、insist后會出現(xiàn)兩種語氣：
he suggested that i （should）turn to my boss.
the expression on his face suggested that he was angry
the old man insisted that he was still young.
the police insisted that we should offer proof.
4. 在主語從句中：it is necessary/important/strange/natural/…that…
5. wish后，從句中的時態(tài)在原本的時態(tài)上退一步。
