________ the help of experienced career instructors, this type of job-hunting training ________ to be very efficient.
[]
A．By; has provedB．With; has provedC．Under; is provingD．With; is proved
试题答案
答案：B
解析：本主题要考查固定搭配的识记及动词的语态。根据help的搭配要求，介词须用with，从而排除选项A、C；动词prove表示事物的性质时，为不及物动词，不用被动形式，于是本题的正确答案为B。 |
