Question

一道英语选择题……

When she came in ,she was surprised to find a stranger____at the back of the classroom with his eyes ____upon her.
A.seating,fixing
B.to seat,fixing
C.having seated,fixed
D.seated,fixed 答案是：D 为什么？？？为什么不是A？

Answer 1

1.seat oneself=be seated
所以，要么是seating himself，要么是seated。 这个就是一种固定用法啦。
一般看到选择题中有seated选这个的概率非常大。
2.还是同一个问题，fix one's eye on=one’s eye was fixed on

Answer 2

fix on/upon 是固定搭配，表示“盯着看”，此处为被动态

Answer 3

为了保持时态一致， to find a stranger____一句话里的两个动词需要用不同形式过渡一下

Answer 4

seating ['si:tiŋ]
座位

Answer 5

被动式
