一道SAT语法问题请教(有关may的过去式)
Pictures of vipers drawn on the walls of caves suggest that prehistoric hunters snake charms to bring good luck.
<>为划线处.这个划线处是对的.
我的问题是:此处的may用来指prehistoric hunter为何不用过去式might呢?还是只有整句时态都是过去式时才可以用might?

may have +过去分词(表示对过去可能发生过某事的推测  );例如:
1、He may have said so.他也许这样说过.
2、They may not have known it before.他们以前可能不知道此事.
might have done 除了能够表推测,还能表示过去本来可以做而实际并没有做.这时带有轻微的责备之意.例如:
The proposal might have been refused.这个建议本该拒绝的.(实际没被拒绝)
关键:may have +过去分词 可以表示对“过去”的推测

个人认为是前面是suggest而不是suggested. 其实但说词义的话might 和 may没有太大区别.

may have +过去分词
