过去几年里的英文

担心：worry about 或be worried about 害怕：be afraid of doing或be afraid to do或be terrified of doing 在过去的几年里：in the last few years 我觉着是对的吧

In the past few years....记得后面要接现在完成时，这个后面接这个时态的题目常考哦。

in the past few years

在过去的几年里inthepast/lastfewyears

担心 worry about害怕 afraid of在过去的几年里 in the past few years虽然可能帮不上忙，但瓦还是发了，呵呵。●﹏●

翻译如下：在过去的几十年里In the past few decades例句：然而在过去的几十年里，引入新的植物药的数量却明显减少了。However, in the past few decades, the number of newly-introduced drugshas obviously decreased.
