题目内容：

If the United States had built more homes for poor people in 1955,the housing problems now in some parts of the country__ so serious.

B .wouldn't have been
C .will not be
D .would have not been
并请问怎么翻译,

优质解答

正确答案选A,这是一个错综复杂的条件状语从句,从句中说的是过去的假设,而主句中是对现在情况的假设,但是都是与事实相反的假设,所以用虚拟语气.从句中与过去事实相反,用had+过去分词,主句中与现在事实相反用would 或wouldn't +动词原形.这句话的意思是：如果美国在1955年为穷人建造了更多的家园,现在这个国家的部分地区的住房问题就不会这么严重了.
