英语非谓语动词几道选择题分析下。

1Don't worry about him,Mom.He's a man-----for all emergencise.A.preparing B being prepared C having prepared D prepared 2.Experts think we won't have clean water to drink unless something -----soon,but much remains ----- about environment protection.A.would be done;doing B,is done;to be done C,will be done;to do D,is done;to do

Answer 1

1
A
he是prepare动作的发出者，应该用主动，所以B、D排除。preparing是动名词做定语相当于He's
a
man
who
prepares
for
all
emergencies.一个为紧急事件做好准备的人。
2、B
unless引导条件状语从句要用一般现在时
后面的空much为被动

Answer 2

D.B
第一题相当于定语从句： He's a man who is prepared for all emergencies.
第二题第一空，“主将从现”所以用is done.第二空remains to be done固定搭配。如remains to be seen等等。翻译为：有待。。。

Answer 3

He's a man----who has prepared-for all emergencise.我认为选C,表示完成,他已经准备好，表主动，准备的动作he能发出，所以用ing。
第二题，从后面判断选择B to be done。前者something is done。后者remain to do。

Answer 4

我认为第一个选C现在分词做后置定语，用have表示从过去持续到现在的动作。第二个选B

Answer 5

1A
2B
