有人说，像现在这样有课上的日子已经不多了，所以我们得十分珍惜每一次上课的机会，免得将来想上课却没得上时后悔。

Someone said we should think much of the chance of attending class as it will end soon, so that we will not repentant when we leave school.

So if you are available and interested in attending that, please come and see me after class.

有时间和兴趣上课的，请在课后来找我。
