d.grow into
高二英语单选The workers are going all out to make the output ——thr
选A.
这题与grow无关.
首先分析句子成分,直接看to 后面.
to make the output grow是目的状语,其中包含了make sth/sb do的结构.
后面的to three times what it was five years ago做状语,表示程度.
译为:工人们全出外劳作以使产量提升为五年前的三倍.
之所以不用by,是因为by和to都可表示程度,但含义不同.
比如:grow to three times指"增长为三倍",现在是原来的三倍.
grow by three times指“增长了三倍”,现在是原来的四倍.
在本题中不能说“增长了5年前的三倍”,要说“增长为五年前的三倍”
所以用to,选A.
