Question

By 16:30,        was almost closing time, nearly all the paintings had been sold.

A．which

B．when

C．what

D．that

Answer 1

A

句意為：直到臨近結(jié)束的16:30，幾乎所有的油畫(huà)才售完�！癬___ was almost closing time”是個(gè)非限定性定語(yǔ)從句，且從句內(nèi)缺少主語(yǔ)。所以用關(guān)系代詞which. D項(xiàng)that不用于非限定性定語(yǔ)從句中。
【考點(diǎn)定位】考查定語(yǔ)從句關(guān)系詞的選用。無(wú)論先行詞是否是表時(shí)間，地點(diǎn)或原因的詞，定語(yǔ)從句內(nèi)成分殘缺，少了主語(yǔ)或賓語(yǔ)，該選用關(guān)系代詞。
