Here are a lot of uses in sentences from ALC.

http://www2.alc.co.jp/ejr/index.php?word_in=%82%E2%82%CE%82%A2&word_in2=%82%A0%82%A2%82%A4%82%A6%82%A8&word_in3=PVawEWi72JXCKoa0Je

I like to use it when looking at specific usages of words to get at their  
connotations and not just the literal translation.
