语法书上说,当含有否定意义的词语放在句首时,后面的句子要用部分倒装,但是下面的句子把no doubt放在句首,为什么后面没有用倒装呢?
No doubt Tom is the cleverest. 汤姆肯定是最聪明的。
No doubt he was just trying to help. 他多半只是想帮帮忙。
No doubt she had many a tale to tell of the old days. 毫无疑问,她有许多往日的故事要说。
no doubt虽然含有否定词no,但整个短语并不表示否定意义,所以当它位于句首时,其后不用倒装语序。类似的表达还有not long ago, in no time。如:
Not long ago he went to work in the south. 不久前他去南方工作了。
In no time he worked out the problem. 他立即算出了那道题。
另外,no wonder(难怪)用于位句首时,其后也不用倒装(注意no wonder为it’s no wonder之省略)。如:
No wonder he was so tired. 难怪他那么累。
No wonder you can’t sleep when you eat so much. 你吃得太饱,自然睡不着。
There was such a draught, no wonder he caught a cold. 过堂风这样厉害,难怪他感冒了。
