1.这句话是一个部分倒装句(not only正常情况下不能放在句首),do在这里属于
助动词前置(do是need的助动词),以完成部分倒装,所以不能删掉。
2.这句话的正常语序是They not only need clothing, they but also are also short of water.
为了强调,将not only置于句首,此时其后的句子通常要用部分倒装的形式(助动词前置,真正的谓语不前置)。相似的例句如下。
Not only has she been late three times, she has also done no work. 她不仅仅迟到了3次,她还没干一点活(has是助动词)。
Not only do they need clothing, but they are also short of water. 他们不但需要衣服,而且还缺水(do是助动词)。
3.有时也可见到不倒装的情形,此时主要见于but also后接省略结构的情况(省略只剩下主语)。如:
Not only my mother was unhappy, but Marian, too. 不仅我母亲不快乐,
玛丽安也不快乐。
4.also此时被省略,当然可以不省略,或将also换成too,
as well(置于句末)。如:
He not only washed the car, but polished it too [as well]. 他不仅冲洗汽车,而且还擦拭了它。
His name is known not only in Japan, but in China. 他不仅在日本出名,而且在中国也出名。
