2)现在完成时常见两种句型:
①主语+have / has been+for短语
②It is+一段时间+ since从句
例如:He has been in the League for three years.或It is three years since he joined the League.他入团已三年了
一.have/has been doing sth.

当后面接有一段时间的词时,或是加表示时间的词时,可以用现在完成时.如果这件事现在还在持续或还在做,则可用
现在完成进行时.
如:I have been skating for 4 hours.
I have finished my homework.所以选A graduated from college已完成了
