any，anything，whatever都可以填吗？

But now,I realize _________ I do can make things better.

答案是anything.

想问一下：

any、anything、whatever，能不能填？

any和anything如何不同？

anything和whatever如何不同？

But now, I realize anything I do can make things better. （正）

But now, I realize whatever I do can make things better.（正）

But now, I realize any I do can make things better.（误）

三个宾语从句剖析：

1. anything I do can make things better：

I do 是 anything 的定语从句。

2. whatever I do can make things better：

whatever I do 是名词性关系分句（简称名词性从句），whatever 身兼两职，what等于 anything that。

但，anything I do 和 whateverI do 有什么区别是：前者可省略 I do，省略后语法仍然正确。后者不能，由于名词性分句需要有“主谓成分”。

3. any I do can make things better （误）

any 可以用作代词或量词，但，它的词义（指人或指物）需要有上下文支持，或者用 of 表明它指人还是指物。比如：

There is a lot of work, but I cant do any.

I can do any of the things.

You will make friends with any of the boys.

就是说，any 指代人或物，需要有语境，不然不可以单独用。

假如原句改为 But now, I realize any of the things I do can make things better. 就能了。
