__are the students__?后面一格到底应该填什么 为什么我看了我的两个同学的答案都写do?
答
必须是doing，进行时态嘛~~
答
what are the students doing?
答
填talking about
答
What are the students doing?
答
what are the students doing?
对句子中的动宾结构提问都用waht... do? 当然有各种时态的变化.
这里是进行时态,所以是what are...doing?
they talked about their hobbies. 对这里的talked about their hobbies提问就是
what did they do?
明白了吗?
