I'd like to share my links. They help a lot if I don't know the way to write something.

Firstly, this is an on-line dictionary.
http://lingvo.yandex.ru/
I like it for the option of looking up the word in other dictionaries (links below) and in several languages...

Here is the site, where you can type in the phrase and see if it's used that way by native-speakers.
www.google.co.uk
If the site doesn't offer the phrase, word combination offered by you, try to find a synonym... ;)

And here is the site, where you can ask any question about grammar, spelling, linguistics (though not all of the answers are professional, but you may find a lot of new things!)
