Question

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

A．with

B．because of

C．a(chǎn)s a result of

D．without

Answer 1

D      

試題分析：考查介詞：A. with有B. because of因為C. as a result of 因為D. without沒有，句意：沒有志愿者的話，11屆中國國際消費者博覽會就不會成功。選D。
點評：做這題一定要弄清句子的基本意義。實際上這里的with相當(dāng)于一個隱含的虛擬語氣，="if" it had not been for the volunteers。
