问题 Some hard plastics can be ______ metals in manufacturing machine parts.

选项 A、substituted for
B、taken the place of
C、replaced in
D、given way to

答案A

解析 短语辨析。本题除D外,其他三个选择都有“代替”之意,但用法各不相同。substitute for以……代替,substitute A for B用A代替B,take the place of代替某人或某人的位置,replace代替,后直接加宾语,故只有substitute for最恰当。
