Look up for the english explanation in the dictionary after translating the Chinese into English through a translator: http://translate.google.com/
Hope they help.
However, I strongly recommend you not to rely on these so much. It's better for you to use an ordinary dictionary more often as it helps in memorizing vocabulary.
http//translate google.com.hk/
It is a good translation tool and website..
For translation C/E, the English meaning can be known.
yet for a word-for-word translation gives you a free translation;
is too good to be free,with listening,all cover,all function,from "Translate Google"
As for English explaination,use the Dictionary.
eg:-Fulfil:-to fulfil certain requirements
--------------to fulfil voluntary work
