“我去一个我上课时候认识的男生家里吃饭”英语如何讲？

1.如果吃饭这件事情已经发生，且只发生过一次，可以这样说：
I went to a boy's home,whom I got to know when attending classes，to have a meal.
2.如果还没有发生，将要发生，且只发生过一次，可以这么说：
I'm going to a boy's home,whom I got to know when attending classes，to have a meal.
3.如果吃饭这件事情已经发生，且不只一次发生，可以这样说：
I went to a boy's home,whom I got to know when attending classes，to have meals.

PS:I went to a guys home who i knew from class.
这句话有点问题，如果你要用这个句型的话，可以这样说：
I went to a guy's home, who I knew from class.
没有必要用限制性定语从句。

I went to my classmate's home for dinner.

Suitable if he is STILL your classmate

Or:

I went to a guy's home whom I knew in class.

I went to boy's home who I knew him when I went to at class.
楼上的，你的句子太难了，你是给老师看还是难为人？
当然有，a 和 guys 怎么能连用呢？
不会的，因为 who 是修饰人的。

楼主的应该可以``

傲梅寒雪,句子有什么难你自己分析不了成分吧!~况且怎么可能用过去式..JU,,
