Question

Zhengzhou will be more and more convenient when Zhengzhou Subway_____ in two years.

A．is completed

B．will be completed

C．will complete

D．has completed

Answer 1

A

考查時態(tài)。主句Zhengzhou will be more and more convenient是一般將來時態(tài)，所以when引導(dǎo)的時間狀語從句要用一般現(xiàn)在時代替一般將來時。且主語Zhengzhou Subway和complete之間是動賓關(guān)系，要用被動語態(tài)。所以選A，一般現(xiàn)在時態(tài)的被動語態(tài)。
