Question

我想请教两个有关非谓语动词的问题
With no rain for three months and food supplies _____ ,the situation here is getting desperate .
A.run out B.has run out C.be runing out D.runing out
Key：A
( A )twice a year,whether it is a car or a bus or a truck,is the rule that every driver must obey in this city.
A.Being examined B.Examined
选A.A的意思不是正在被检查吗?为什么不选B?

Answer 1

with+sth+doing/done,如果sth与动词是主动关系就用doing,是被动就用done.本句还原是food supplies are run out.用run的过去分词run
being examined不是非谓语动词,而是动名词做主语.动词是不能作主语的,过去分词形式不能做名词,而ing形式可以作名词,此处缺主语,只能选a
