选择题
With coal and oil , what long-term effects of global warming on humans will be?
A.run out of
B.are using up
C.run out
D.running out of
答案
答案:A
题目分析:考查with的复合结构。with + n + doing /done/ to do,选择哪个非谓语动词的形式,要看动词和所修饰的名词之间的关系,即看coal and oil 与run out of 之间的关系,二者之间是被动关系,所以用run out of(run的过去分词),正确答案为A。而与run out之间是主动关系,所以选C应该用running out,选D把of去掉,选B用used up,因为和use up之间是被动关系。
