Question

 The construction of the two new railway lines _______by now.

A. has been completed              B. have been completed

C. has completed                   D. have completed

 

Answer 1

【答案】

 A

【解析】從句子的主語the construction可知，謂語動詞應(yīng)是單數(shù)形式，排除B和D；從句意“兩條新鐵路的建設(shè)到現(xiàn)在已經(jīng)完成了”可排除C。

【考點】考查動詞的語態(tài)和主謂一致

【易錯點】受two new railway lines的影響，誤選B。

【備考建議】分清句子的結(jié)構(gòu)，理清句子意思，定位切點，做出準(zhǔn)確判斷。
