懂英语的请进,How long were they playing football yesterday?
How long were they playing football yesterday?
这里面的playing 是怎么用的?是什么词性,-ing不是现在进行时吗?为什么are已经变成were了,后面play还要用playing形式!
另外请说明一个过去分词
懂英语的请进,How long were they playing football yesterday?How long were they playing football yesterday?这里面的playing 是怎么用的?是什么词性,-ing不是现在进行时吗?为什么are已经变成were了,后面play还要用playing
现在进行时: am / is /are + doing
过去进行时: was/ were+ doing
过去分词用于现在完成时和过去完成时态,规则变化同过去式,不规则变化需要单个去记
如: do --- did---- done
这是过去进行时的用法,was/were+doing 表过去正在做某事
play是固定搭配,play是动词,这个句子是过去进行时,表示在过去某一时刻或某一段时间内进行或发生的动作,其形式为was /were + V-ing,你这个句子翻译是:昨天他们踢了多长时间的足球?
表过去进行时
How long were they playing football yesterday?
翻译过来就是:他们昨天打了多长时间的篮球?既然是昨天,当然要用are的过去时were,be doing sth. 表示正在做什么,是进行时态。
