Today ,the forest have almost gone.People must ____ down too many trees. A,stop to cut B,stop from cutting C,be stopped to cut D,be stopped from cutting 顺便解释一下
cut, pierced, must be finished, who's house, shouldn't be touched 补充: 句型转换。 1.They must finish mending the machine in three days, The machine ____ ____ ____ mending in the days. 其实这一句很奇怪,怎么看都不像老外说的英语!老外没人说mend的啦!一般是Fix, 或者repair。另外这个根本就不是一个正确的句子,如果转为被动语态应该为 Mending the machine must be finished in three days!

D 根据句意,大量的树林已经消失,人民必须被制止去大量地砍伐树木 因此,应用被动语态,排除AB stop to do something 表示停下来去做别的事情 stop doing表示停止做某事 若选C,则变成停下来,去砍伐树木,不合题意 因此为D

D 因为被动语态是 be+动词过去分词--排除A.B 又因为 stop的用法是 stop from doing Sth.--排除B
