Every Monday morning, students in our school would stand at attention, watching the national flag ______. A. raising B. rising C. being risen D. being raised 答案是D,请问B为什么不对
选D being raised 解析:因为国旗是不会自己升起的,是被升起的,所以要用被动语态. Every Monday morning,students in our school would stand at attention,watching the national flag being raised. 每周一早晨,我们学校的学生会立正观看升国旗.
