Question

Is this the reason ______ at the meeting for his carelessness in his work?

A．What he explained	B．how he explained
C．he explained	D．why he explained

Answer 1

C

解析試題分析：句意：這就是那個(gè)你在會(huì)上解釋的工作上粗心的原因嗎?reason作先行詞時(shí)，如在定語(yǔ)從句中作狀語(yǔ)，用why引導(dǎo)定語(yǔ)從句；如果作主語(yǔ)或賓語(yǔ)，則用which/that引導(dǎo)定語(yǔ)從句。在這個(gè)題目中reason作賓語(yǔ)，因此，省略連接詞which/that。What不能引導(dǎo)定語(yǔ)從句；根據(jù)句意故選C。
考點(diǎn)：考查定語(yǔ)從句的用法。
