Question

Thanks to the economical development, workers' wages have increased ________ as far as 200% in the recent three years.

A．for

B．to

C．up

D．by

Answer 1

D

試題分析：考查介詞的用法。increase by “凈增了,以…比率增長”,類似的表達 grow by, rise by等...，而如果是“增加到”則用increase to ,grow to, rise to.句意：多虧了經濟的發展，工人的工資在近三年已經增長了高達200%。
點評：英語中表達“增加或減少了多少的幅度”用介詞by+比率。如：price was reduced by 18 per cent.價格降低了百分之十八。而如果是“增加/減少到”則用increase /grow /rise /reduce to.
