单项选择题
As a developing country, we must keep ______ with the rapid development of the world economy.
A．move
B．step
C．speed
D．pace
答案
参考答案：D
解析： keep不与move、speed搭配，故可排除B、C。keep pace with(=hold pace with)表示“跟上，与……同步，并驾齐驱”，如：Are wages keeping pace with inflation 工资的提高能否与通货膨胀同步 keep step with“整齐步调”与句意不符。所以，答案为D。
