Question

一个小小的英语问题：students learn their lessons in class.they sit in the classroom listening to

students learn their lessons in class.they sit in the classroom listening to the teacher carefully. 这儿listen为什么要加ing呢？？ 求详细解答。。

Answer 1

they是主语，sit in the classroom是谓语， listening to the teacher carefully是现在分词做伴随状语，原句可改为they sit in the classroom，and listen to the teacher carefully at the same time ,但就没有那种同时发生的韵味了，英语中经常用分词，不定式做状语

Answer 2

前面已经有动词sit了，说明这是一个伴随性状态，伴随性动词＋ing

给你举个例子：The teacher came into the classroom，handing a book in one of her hands.（通常伴随性动词前面有逗号！！）
有些是不需要的：I like sleeping with the window open（with+sth+形容词）

如果有and连接，那前面什么时态，后面也什么时态

求采纳！谢谢

Answer 3

listening在这里表示主动 进行。
如果 classroom前面加上and
那么就是连接两个并列成分。这时候 listen 用原型：
students learn their lessons in class.they sit in the classroom （and） listen to the teacher carefully.

Answer 4

listening to the teacher carefully是一个状语从句，伴随性状态

Answer 5

学生坐在教室里学习功课

Answer 6

表示进行时
