单选题 I told the driver that he had knocked two people ______ their bicycles and had nearly caused a had accident.

[A] into
[B] off
[C] on
[D] out of

【正确答案】 B

【答案解析】考查搭配。knock能与四个选项都构成搭配：knock into撞进，撞上；knock off撞倒；knock on撞上；knock out of撞出。但是本题并不是考查这种固定搭配，因为空格后的宾语是bicycles(自行车)，所以用into、on、out of都不合逻辑，只有off可表示从交通工具下来之意，因此是正确答案。
