A. stop to cut B. stop from cutting
C. be stopped to cut D. be stopped from cutting
答案选哪个?为什么?

D. be stopped from cutting

必须被阻止再砍树,就是停下。

stop to do停下手头事,干另一件,

stop doing停下正在干的。

D

B. stop from cutting

如今,森林几乎已经消失了,人类必须停止砍伐大量的树木.

stop from doing sth. 停止做某事

stop to do 是停止去做某事

选B stop from doing 表示停止做某事
stop to do 表示停下来去做某事
由此可删去A和C
be stop 表被动,人们应停止砍伐树木

D
stop from前面要加被动,被阻止去……
