　　 chance ,opportunity的区别

　 chance表机会，但具有较多的偶然性 例：

　　 This gave him a fair chance.

　　 I met him by chance.

　 chance 比opportunity语意重些，特别是在含有否定意义的句中。例：

　　 He had no chance to attend college because of poverty .

　 opportunity指一般的机会，特别指对自己有利的机会。例：

　　 I’m glad to have the opportunity of talking to you .

　　 This will be a good opportunity to explain that to her .

　　 注意：take an (the )opportunity得到机会

　　 take a (the ) chance碰运气

　　 两者区别很大。

2.He ______ more help, even though he was very busy.

A. might have given　　 B. might give　　　 C. may have given　　　 D. may give

　　 解析：“may/might+不定式完成体”都可用来推测过去发生某事的可能性，但“might+完成体“，语气更为不肯定，常有否定意义，即某事可能发生而却未发生，暗含责备意味。本题含义明显：he即使很忙，也有可能给对方更多帮助，然而事实并非如此。“may+完成体”则不具备这种含义。
