英语试题they must finish the work tomorrow改为被动语态和don't take my e

The work must be finished by them tomorrow.
被动语态的话就是指把动词后面的动词提前做主语,如果不是主语不是人（I, you, they等等）的话,那么就要用被动语态.这句话就是工作被完成.
Don't take my English book aways without permitting
without 后面要+动名词形式
You can get plenty of information on the interent
我觉得那个可能是个拼写错误吧?plenty of 大量的··

the work must be fininshed tomorrow.
permision
我也很想知道OLENTY是什么意思。非常抱歉。 you can get___(olenty)of on information on the internet 打错了 是Plenty。！！题目是不是you can get_____plenty of information on...

The work must be finished by them tomorrow.
permiting 介词后面用ing

The work must be finishied tomorrow.
permitting
