Question

(尽管他来新学校不久，但和同学们相处得很好) 用英语怎么写

Answer 1

Although it is not long/has not been long since he came to the new school,he gets along very well with his classmates.
或者
Although it was not long/had not been long since he came to the new school，he got along very well with his classmates.

注意：since引导的从句必须采用一般过去时，而主句是一般现在时或现在完成时。

友情提醒：1楼的答案是错误的。第一，主从句时态不一致；第二，翻译得像中式英语，怀疑是用机器翻译的。 个人拙见，请楼主斟酌。

Answer 2

Although he came to a new school soon, get along very well and students.或
He came to a new school soon, but get along very well and students.
记住although和but不能连用，只能取其一。翻译是要翻译 尽管~~~~，但是~~~~~。
有不会的还可以问我。
希望采纳
