If law and older ___ not preserved, people will not be able to live a secure life.
A.are
B.were
C.is
D.was
选哪一个啊?~~请详细解释~~谢谢
为什么不选A啊???
正确答案是选C

C

C - IS

解释:
因为是动词的单复数是按照前一个单词的形式而定, 这句话虽然有LAW AND OLDER, 但是OLDER 不是复数形式; 并且后面的WILL NOT 显示并不是虚拟的过去形式,故只能选择C.

D.

答案是 B , 解释如下:

- law and order 是众数, 所以一定是 are / were
- 因为 "if" 是假设的语句, 要用过去式, 所以是 B "were"
