The police_ looking for the lost dog at the station at that time 是不是填 were
问题描述：
The police_ looking for the lost dog at the station at that time 是不是填 were
答
是用复数的,这个The police 是表示一类人,还比如The rich ,The poor富人,穷人,后面都是要跟复数的,这要特别记一下,语法书上也都有说明的
举例The old are taken good care of in our country.老年人在我们国家得到了很好的照顾.
The young need to take care of the old.年轻人需要照顾老年人.这个句子是什么时态的呢？这个句子当中有一个很明显的时间点，at that time在那时，相对于现在而言的话是过去时，所以要用were那 were looking for 呢？be+doing是现在进行时，所以这个当然是过去进行时罗，是过去正在寻找的意思
