I am brushing up on what little French I learned when I used to take classes two years ago and I'm looking for a reference where I can look up verbs and find plenty - no, LOTS - of examples where the verbs are used in sentences. My book 501 French Verbs provides only three sentences per verb. I have other grammar textbooks where each new verb being introduced is only used once or twice. Any suggestions? Books and searchable websites will also do.
