You shouldn't laugh for others in public

You shouldn't laugh for others in public
You shouldn't laugh for others in public

You shouldn't laugh for others in public
有个短语
取笑某人是laugh at
所以 for改成at

You shouldn't laugh at others in public.
laugh at ..是笑话...的意思。
“英语教师团队真诚为您解惑!”

for改为at laugh at固定搭配 嘲笑

改为 You shouldn't laugh at others in public
这里又一个 词组 就是 laugh at sb
应该没有 laugh for 这个用法。
希望采纳 谢谢！
