Question

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

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

Answer 1

A

試題分析：句意：這就是他在會(huì)上解釋的他的工作上的疏忽的理由嗎？這里是定語(yǔ)從句，先行詞是reason，關(guān)系詞在從句中作explain的賓語(yǔ)，當(dāng)然可以省去，how與why在從句中作狀語(yǔ)，不能作賓語(yǔ)，故排除CD；what不能引導(dǎo)定語(yǔ)從句，故選A。
點(diǎn)評(píng)：本題難度適中。定語(yǔ)從句的考查關(guān)鍵在于定語(yǔ)從句的成分分析，如果缺少主語(yǔ)，賓語(yǔ)，表語(yǔ)，定語(yǔ)就使用關(guān)系代詞，否則，就使用關(guān)系副詞。
即學(xué)即練：A large number of students give messages to their close friends through this radio club, ______hosts are all their schoolmates.
A. that          B. of which         C. which      D. whose
解析：D。whose 在從句中作定語(yǔ)，修飾hosts。
