同学你好~
ever用作副词,意为“曾经、以前、无论何时、总是”等，其用法比较灵活，不一定就是使用过去时或者完成时，现归纳如下：
一、用于一般疑问句,意为“曾经、这以前”现代汉语中一般不译出.
Does she ever go out at night?她通常晚上外出吗?
Have you ever been to Beijing?你曾去过北京吗?
When you were working there, did you ever meet a foreigner?你在那里工作时曾见过外国人吗?

二、用于否定句,意为“无论何时都不……,至今不曾……”.
Nothing ever happens in the lonely village．这个遥远的小村子至今未出过事.
We hardly ever go shopping there．我们至今未在那里买过东西.

三、用于条件句,译为“曾经、有机会”.
If you ever come to Beijing, please let me know．如果有机会来北京,请告诉我.
If you ever have any problems, please call me．你若有问题,请打电话.

四、与比较级连用,译为“以前、以往、任何时候”.
It is raining hard than ever．雨下得比以前更大了.
When she got the letter, she became angrier than ever．拿到信时,她比以前更生气了.

五、与最高级连用,译为“空前、有史以来、从来没有”.
I think she is the best actress ever．我认为她是至今最优秀的演员.
This is the biggest harvest ever．这是空前未有的大丰收.

六、与疑问词连用,加强语气,译为“到底、究竟”.
When（where）ever did you see the pan-da?你到底在什么时候（哪里）看见那只熊猫的?
Who ever disagreed with you?究竟是谁不同意你?

七、口语中,用于带有be的疑问句加重语气,表感叹.
Is she ever a beauty?她真漂亮!
上句可换为：
Isn't she a beauty?
What a beauty she is!

同学的句子是上述第四种用法~
