Online resources for studying grammar/constructions

[xianhua]

OK, so I'm faced with the sentence:

除了钱,你送什么礼物都有可能是不合适的.

I can see from my Boya text book, that the 什么 and 都 form a construction. Where can I go online for a good explanation of such constructions? Is there such a website where I can just type in 什么 and 都 and get an explanation? I realise there are some good books on grammar, but would prefer to avoid the cost if possible. As I've said before, there are gaps in my learning and some things which I should know, are not known (or have been forgotten).

http://comet.cls.yale.edu/chineseusagedictionary/ is one. It does not seem to have your particular example, however.

I'm not aware of a good grammar resource on the internet.

But 什么 + 都 = everything, 谁+都 = everyone, 哪里+都 = everywhere, etc.
