please take he to the classroom有错吗?mr.li teaches we englishi favorite subject is chinesehim is my friend lilei

。。。都是错。。。
please take him to the classroom
Mr. Li teaches our English
My favorite subject is Chinese
He is my friend Lilei

这位朋友，这个是有错误的。
因为he在这里做take的宾语，所以要用him

你下面的补充也有问题，帮你改一下，供你参考吧。
Mr. Li teaches us English.
My favorite subject is Chinese.
He is my friend Lilei.

希望对你有帮助。

please take him to the classroom.
Mr. Li teaches us english.
my favorite subject is Chinese.
he is my friend LiLei.

没错！

please take him to the classroom 【他】在这里做take的宾语,所以要用宾格形式
Mr.li teaches we English 正确
i favorite subject is chinese 应该是my.
him is my friend lilei 【他】做主语,要用主格形式,he.
你最好把主宾格仔细看一下,练习一下,熟练了就好了.
