At no time do the plain look so perfect as in early autumn.这里的倒装句为什么有个do?
问题描述：
At no time do the plain look so perfect as in early autumn.这里的倒装句为什么有个do?
答
正常语序应该是
The plain doesn't look so perfect as in early autumn at any time.
这里有doesn't这个助动词,那么当at any time变成at no time的否定形式放到句子开头倒装后,doesn't就便成肯定的does了
不知道说清楚没有～
