一个英语句子,不清楚写的对不对,
If CNN has broadcasted interesting news about president Obama one day,I am sure the main topic among my friends would include this thing.这里has 和 am 用过去式么?这算虚拟语气么?
此句是虚拟语气,
此句原本是 主将从现 但因为虚拟语气(假设,实际 并未发生),实际都各推后一个时态(而并非是变为过去时态).
即由:If CNN broadcasts.I am sure the main topic among my friends will
变为:If CNN has broadcasted ...I am sure the main topic among my friends would
has已经是推后一个时态,am不受虚拟语气影响
has和am都不用变
