一点英语翻译问题我看见每个人都在认真听课I see everyone is listening to the teacher carefully是否有误?尽量不要犯这种简单的语法错误Try not to make mistakes in _________

I saw everyone in earnest
Don't try to make this simple grammatical mistakes

正确:
(1)" I noticed that everyone was listening seriously to the teacher."
(2) "I noticed that everyone was listening attentively in the class."
:
(a) "Try not to make simple grammatical errors."
(b) "Try not to make silly [糊涂的] mistakes in (English) grammar."
(c) "Try to avoid making simple/silly grammatical errors."

“I see everyone listening to the teacher carefully”
see后面可加do，表示看见某人曾经做过什么
后面加doing表示看见某人正在做。
所以不能加is
或者可以改成“I see that everyone is listening to the teacher carefully“。写成宾语从句。

grammars

1\I see everyone listening to the teacher carefully.这句是一个完整的句子,一个句子当中不要两个谓语,（实意动词see,系动词is）,之时一个简单句,后面的动宾短语是做宾语补助语.
2、Try you best not to make this simple grammar mistakes .
