英语：当以here,there,only开头时,句子怎样倒装

Here there这是方位副词至于句首时的倒装句形式,要用完全倒装.也就是说,要把谓语动词提到句首.(不完全倒装指的是把助动词提前),给你举个例子吧,A car comes here.若把here提到句首,就要把动词comes提到句首,变成Here comes a car.There的用法和它一样.至于Only,是指的“Only+状语”置于句首时的倒装,主谓语需要倒装.例如下面两个句子：
 1) Only by practicing a lot outside class can we speak English fluently.这里we can变为了can we 2) Only when I saw him did I remember that I promised to bring him a gift.这里是I remembered变为了did I remember
not only位于句首时的倒装,也是局部倒装.例如,Not only did we lose our money,but we were also in danger of losing our lives.把we lost这个正常语序变为了did we lose这种助动词提前的形式
明白了吗
