ответьте на вопрос: unfortunately i don't have enough time to surf the net but i`d like to do it.which sites would you recommend visiting?

I would recommend you visiting only two sites - yандеx and wikiпедиia. Visiting yaндекс you can find all the important news that happen all over the world. Visiting wikipедиa you can find all the information you need for your homework. All other internet sites are useless,they are just killing your time.
