ＧＷＤ２５　１８请教

In contrast to environmentalists proposals to limit emissions of certain
pollutants, the administration proposed calling for mandatory restrictions of
only three such pollutants from power plants-mercury, sulfur dioxide, and
nitrogen oxides-and the plan would delay such cuts until 2010 or later.
A administration proposed calling for mandatory restriction of
B administration proposed a call for mandatory restrictions, including those for
C administration, proposing mandatory restrictions on
D administration’s proposal was a call for mandatory restrictions, which include
E administration’s proposal would call for mandatory restrictions on

答案是E,　相比之下，我承认这个选项最好．但是对那个would call for 不能理解．请帮忙讲解一下吧．

up

would call for = 提出，提倡

it is a good use here

mbz真是好人啊,我还是对 would很不解

谢谢pigy提醒.

晕死,我没看到后面的那半句。只看到几个pollutants ,以为这句话就完了,都没看后面还有半句.要好好反省了.以后看仔细了再上来问问题.
