小深给大家谈谈boil及物吗，以及boil及物还是不及物应用的知识点，希望对你所遇到的问题有所帮助。

1、前边是had been boiling,后边是was taken首先就句型及意思而言就决定了前边是过去完成时,后边是过去时,而且是被动语态由于水持续沸了3分钟,也就是一直在沸,所以要在过去完成时的基础上加上进行时当然也可以是has been boiling和is taken,不过要看具体语境had been boiling ,was taken壶里的水滚了三分钟之后才被从炉子上拿开has to be boiled; is taken整句时态应为一般现在时The kettle water was boil for 3 minutes before it had taken away from the stove.had boiled, was takenhad boiled, was taken .。

本文到这结束，希望上面文章对大家有所帮助。
