scarcely / hardly 遇见单数名词做及物动词的宾语的时候做倒装时可以是:
He hardly spoke a word.
=Hardly a word did he speak.
那如此倒装对不对?
Hardly did he speak a word .
谢谢回答！
▲在一般情况下，当表示否定意义的副词（如hardly, never, seldom, little, rarely等）被置于句首时，其后的句子用部分倒装的形式（与通常疑问句形式相同）。如：
Hardly had he arrived when she started complaining. 他刚到她就抱怨起来。
Little do they know about her alternative career. 他们对她的另一个职业一无所知。
Never before had he seen so many people starving. 以前他从未见过这么多人挨饿。
Rarely have I seen such a beautiful sunset. 我极少见到如此漂亮的日落。
Seldom do we hear such fine singing from school choirs. 大家极少能听到学校的合唱团有这样好的歌唱了。
所以，你的以下倒装方法是对的，这也是最一般的做法：
He hardly spoke a word.
=Hardly did he speak a word.
▲除上面的倒装外，还有与之一样的另一种倒装，即当否定词修饰宾语置于句首时，其后的句子也用部分倒装的形式（与通常疑问句形式相同）。如：
Not a word did they exchange during the meal. 在吃饭时他们一句话也没交谈。
Not a single mistake did I find in your composition. 在你的作文里，我找不到一个错误的地方。
所以你的问题中的以下倒装也是对的：
He hardly spoke a word.
=Hardly a word did he speak.
