英语语法问题,详解者追分
1】That particular Yellow has
been the official bus color for quite a long time
这里的has been只是已经的意思吗?有没有省略pp?
2】children were being transported to school In all sorts of
vehicles,including trucks and horse-drawn wagons.
这个句子倒是是什么句型?

答案

第一句,因为有for a long time ,因此是现在完成时
has been 的been 就是be 动词的过去分词,has 是现在完成时的助动词
如果是一般现在时,则是
that yellow is the bus colour
现在完成时,则是,that yellow has been.
第二句
were being transported 是过去进行时的被动
过去进行时的被动：was/were being done
从句的including 是介词
孩子们正被各种车辆送去上学,其中包括卡车和四轮马车
