whatever

1.whatever跟what ever不同，参见ever 5

2.whatever比whatsoever普通。

3.Do whatever you can里的whatever和Do it，whatever happens里的whatever都是关系代词，但第一句里的whatever是what的强势式，第二句里的whatever是表示concession的，有“虽然有什么”的意思，比较下面两句：

• Whatever he has done he repents. （他不论做了什么总要后悔。repents是及物动词，把whatever里的what做宾语。）
• Whatever he has done, he repents. （他虽然做了什么，却是后悔的。［他也许做过坏事，但他能后悔，也是可取的。］repents是不及物动词。）

4.下面两句里的关系代词that都该删去。

• You may write about whatever subject that interests you.
• I shall be glad to consider whatever suggestions that you may offer.

5.下面三句都合乎习惯：

• Whatever the causes, a change took place.
• Whatever the help I have received, I am responsible for the whole work.
• Whatever the ultimate conclusion reached, the discussion ought to prove of great interest to all concerned.

第一句里可以在causes后面加上may have been，第二句里可以在received后面加上may have been，第三句里可以在reached后面加上may be，但都不及原句自然。第二句里也可以把help前面的the省去，第三句里也可以把ultimate前的the省去，在reached前面加上may be。
