Question

This August will be very precious for graduates by which time they _________into a university.

A．will be admitted	B．will have admitted
C．have been admitted	D．will have been admitted

Answer 1

D

試題分析：考查時(shí)態(tài)及語(yǔ)態(tài)的用法。主句中will是表示將來(lái)時(shí)，在從句中有by which time可以看出從句謂語(yǔ)動(dòng)詞應(yīng)該用將來(lái)完成時(shí)，又因?yàn)閠hey與admit之間是被動(dòng)關(guān)系故選D；將來(lái)完成時(shí)表示將來(lái)某個(gè)時(shí)間之前已經(jīng)完成的動(dòng)作，常與by+將來(lái)的時(shí)間；這里指八月以前學(xué)生已經(jīng)被大學(xué)錄取了。一般將來(lái)時(shí)指將要發(fā)生的動(dòng)作與將來(lái)的時(shí)間狀語(yǔ)連用。
點(diǎn)評(píng)：本題難。命題者在于考查學(xué)生的將來(lái)完成時(shí)與一般將來(lái)時(shí)的區(qū)別，學(xué)生誤選A，認(rèn)為是將來(lái)時(shí)而忽略了by which time的這個(gè)時(shí)間狀語(yǔ)。
即學(xué)即練：Pick me up at 8 o'clock,I  __________ breakfast by then.
A. will have            B. will have had   C. have             D. have had
解析：B句意：早上8點(diǎn)鐘你來(lái)接我，到時(shí)我已經(jīng)吃完早飯了。
