题型：不详难度：来源：

So far nobody has provided ______ hard evidence to support their claim that they have seen _______ UFO.

A．an; a

B．the; the

C．不填；a

D．不填；an

答案

解析

试题分析：考查冠词用法。第一空的evidence是不可数的抽象名词证据，单独使用不要冠词；第二空用a/an+单数名词表示一类事物。因为UFO是辅音发音，所以使用a。句意：到目前为止，没有人能提供有力的证据来证明他们看见过UFO。故C正确。
点评：冠词的考查集中在the表示特指，a/an表示泛指；以及冠词的一些固定搭配和不或死于冠词的情况，如抽象名词，物质名词前面不要使用冠词。
