"Be careful when you cross this very busy street. If not, you may ________ run over by a car.
A. have
B. get
C. become
D. turn"

Answer 1

答案B
have run为主动形式，与句意不符；turn作系动词时，多接表示性质或颜色的形容词或名词，一般不接过去分词短语；become虽然接过去分词短语，但不宜与这里by短语连用．这里强调动作的被执行，相当于被动语态be run over by a ear，即“被汽车碾过去”．故用get，同时更为准确地表示突然发生、未曾料想到的事态．
