he has put on weight during the last two weeks.
为什么用现在完成时,而不用一般过去式?
解题思路: during the last+时间段,是算到说话时为止的一个时间段,“在过去的。。。。一段时间中”,是现在完成时的标志性状语
解题过程:
during the last+时间段,是算到说话时为止的一个时间段, “在过去的。。。。一段时间中”, 是现在完成时的标志性状语
若表示从现在算起的过去一段时间内,通常要与现在完成时连用。如:
This company has come a long way in the last five years. 最近五年这个公司已经前进了一大步。The house has changed hands three times in the last two years. 在过去两年中,这栋房子已转手三次。
Is that the sum of what you’ve done in the last two years? 这就是你最近两年中完成的全部数量吗?
现在完成时标志性词语:already, yet, so far, as yet, lately ,recently,these days/weeks/years, until now, up to now, since+ 时间点, for+时间段, in the last/past( few years)等
