Lingling isn't in the classroom, but the library.
(Lingling 不在教室,她去图书馆。)
英文:Lingling isn't in the classroom,She's in the library.
我是搞英文专业的,肯定没错。
Lingling isn't in the classroom,she has gone to the library.
Lingling isn't in the classroom.She is in the library.
这要看你的本意的闹~~
不过我想一般的情况应该是
Lingling isn't in the classroom.She is in the library.
另外....问一下~~名字是不是要写成Lily〔中文,铃铃〕
