Question

【題目】China’s Silk Road Economic Belt, ____ accomplished, will quicken the economic growth of the countries along the route.

A. as B. once

C. though D. unless

Answer 1

【答案】B

【解析】

考查狀語(yǔ)從句。A. as由于； B. once 一旦； C. though盡管； D. unless除非。句意：中國(guó)的絲綢之路經(jīng)濟(jì)帶一旦建成，將加快沿線國(guó)家的經(jīng)濟(jì)增長(zhǎng)。分析句子結(jié)構(gòu)可知，此處考查狀語(yǔ)從句的省略，表示“中國(guó)的絲綢之路經(jīng)濟(jì)帶一旦建成”，所以once符合語(yǔ)境。故選B。
