A from running B to run C in running D running

应选什么呢?原因? 各选项是什么意思?

谢谢

选A 树能帮助防止水分流失
B没有这种说法
C也没有这种说法
D的意思说 让水分持续流失,跟题意不符.

A.

阻止水的流失

keep from doing sth.

A

keep water from running
阻止水流失

固定短语:keep sth. from doing sth.

keep from doing sth. 固定搭配

选 A .
这个句子关键是在"keep "上.初三英语书上有的.
stop sb from doing sth
keep sb from doing sth.都表示阻止某人做某事.
其中 用"stop" 时. 单词 "from"可以省略.
但是用keep 时,"from"不能省略.所以选 A.

keep/stop/prevent sth/sb from doing sth. 固定搭配,意思是阻止某物/某人做某事
