Question

一When shall we start the restoration of the historic buildings?
一Not until our plan________ by the committee.

A．will be approved

B．a(chǎn)pproves

C．is to approve

D．has been approved

Answer 1

D

試題分析：until連接的是時(shí)間狀語從句，不能用將來時(shí)故排除A；又因?yàn)閜lan與approve之間是被動關(guān)系。故選D.
點(diǎn)評：動詞的時(shí)態(tài)和語態(tài)放在一起考查增加了試題的難度，需要考生有分析理解復(fù)雜的句子結(jié)構(gòu)的能力。
即學(xué)即練：—Tony, come down and help me with the heavy box!
— Come on! I _______ all day long．Get Peter to do that!
A．work                            B．had been working
C．had worked                       D．have been working
解析：D�？疾闀r(shí)態(tài)。根據(jù)關(guān)鍵詞all day long可知使用現(xiàn)在完成進(jìn)行時(shí)，現(xiàn)在完成進(jìn)行時(shí)表示動作的持續(xù)性和延續(xù)性。句意：—Toney，來幫我搬這個(gè)重盒子�！�算了吧！我一整天都在上班。讓Peter做吧。故D正確。
