Question

-- Be careful, _______ you will make mistakes in your exams.
--I know that, Mrs. White. One can never be too careful.

A．a(chǎn)nd

B．or

C．nor

D．but

Answer 1

B

解析試題分析：句意：認(rèn)真點(diǎn)，否則你在考試中會(huì)犯錯(cuò)。我知道了，懷特老師，一個(gè)人永遠(yuǎn)不可能太認(rèn)真的。and和， or或者，nor也不， but但是；根據(jù)語境可知不認(rèn)真就會(huì)出錯(cuò)，故選B.
考點(diǎn)：考查連詞
