第二句:
近年来,中国在减少空气、水和土壤污染上取得了显著成效。
译文一:In recent years, China has achieved remarkable results in reducing air, water and soil pollution.
思路:“近年来” 表明动作从过去持续到现在,时态用现在完成时。
句子主干:“中国取得了显著成效” → China has achieved remarkable results
“在减少空气、水和土壤污染上” 作状语 → in reducing air, water and soil pollution
译文二:in the last few years, China has obtained notable achievements in decreasing air, water and soil pollution.
译文三:Recent years have witnessed China's significant achievements in the reduction of air, water, and soil pollution.
思路:表示某个时间(段)或地点发生了什么事情,可以用这个时间(段)或地点做主语,谓语动词用see或者witness。
