Question

The 11^th China International Consumer Goods Fair could not have succeeded         the volunteers.

A．with

B．because of

C．as a result of

D．without

Answer 1

D      

试题分析：考查介词：A. with有B. because of因为C. as a result of 因为D. without没有，句意：没有志愿者的话，11届中国国际消费者博览会就不会成功。选D。
点评：做这题一定要弄清句子的基本意义。实际上这里的with相当于一个隐含的虚拟语气，="if" it had not been for the volunteers。
