    Thanks to the economical development, workers' wages have increased ________ as far as 200% in the recent three years.
    A．forB．toC．upD．by
    D

    试题分析：考查介词的用法。increase by “净增了,以…比率增长”,类似的表达 grow by, rise by等...，而如果是“增加到”则用increase to ,grow to, rise to.句意：多亏了经济的发展，工人的工资在近三年已经增长了高达200%。
    点评：英语中表达“增加或减少了多少的幅度”用介词by+比率。如：price was reduced by 18 per cent.价格降低了百分之十八。而如果是“增加/减少到”则用increase /grow /rise /reduce to.
