Richard, thank you so much for your comments. I totally agree with you. Actually it's difficult for me to distinguish "seek" from "look for/find/discover", and also I often meet this kind of problem. When the meaning of two words looks like similar, I don't know which one I should use.

Tania... here are a couple of suggestions for writing your question: (1) I'd like to (seek) FIND some good websites for learning English. [seek means "look for", but what you want to do is "find/discover" some websites. (2) We "recommend" SOMETHING, for example " recommend a few good ones OR recommend a good restaurant OR recommend a good movie. We don't say "recommend me/you/him/her/it/ etc." because the verb recommend is a transitive verb that requires an object after the verb (usually a noun like 'website/restaurant/movie = something/a thing). So, the sentence should be "I'd like to find some good websites for learning English. Could you recommend a few good ones?
