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
因为Look是个实义动词，所以要借助助动词do 的适当形式，如果是一般时就用do/does,如果是一般过去就用did
答
因为它是倒装句嘛，当然有个do了
应该是does吧？plain不是单数吗？
At no time does the plain look so perfect as in early autumn.
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～
答
