over the past years用什么时态？

Question

如题所述

Answer 1

over the past years 时态用现在完成时。

over the past years意为“在过去的数年”，通常情况下题干中出现over the past years，谓语动词为现在完成时态

例句：

1、Chinese filmmakers have won several prizes at events over the pastyears.

中国的影片制作人过去几年中已经在此电影节中多次获奖。

现在完成时标志词

1、already

用在肯定句中（be动词、助动词、情态动词之后，实意动词之前）常与yet进行转换。

例如：I have already finished the work.

我已经完成这项工作了。

改为否定句：I haven't finished the work yet.

我还没有完成这项工作。

2、yet

放在否定句和一般疑问句句末。

其他的标志词：just，before，recently,still，lately，never，ever，twice，on several occasions，in the past/last few days/weeks/months/years，（up to)these few days/weeks/months/years,this morning/week/month/year（多用于一般过去时），up to present，so far，up to now，up till now，till now。

3、since+时间点＝for+时间段＝since+时间段＋ago

since+一般过去时态的时间状语从句。

例如：He has been here since he joined the army.

自从他参军以来，他一直在这儿。
