Question

There is ____ Mr. Smith at the door who wants to speak to you.

A．a(chǎn) some

B．certain

C．some a

D．a(chǎn) certain

Answer 1

D

試題分析：句意：在門口有位想要跟你說(shuō)話的史密斯先生。certain某，某一； a certain Smith 一個(gè)叫做史密斯的人。some〔用于單數(shù)普通名詞前〕(有)一個(gè)(人、物、時(shí)間)。 He went to some place in Africa. 他到非洲一個(gè)地方去了。We must find some way out of it. 得想一個(gè)方法逃脫才行。some 是指完全不知道的事物而言， a certain 則是在知道而故意不說(shuō)時(shí)、或輕蔑地說(shuō)‘某一個(gè)…’時(shí)用,故選D。
考點(diǎn): 考查不定代詞的用法。
