倒装的实质就是强调。
第一句中由于是强调原因“不仅因为...而且因为...”,所以应该是:
..., because not only does it...but also it is...。
第二句三楼的说的没错,neither...nor都属于部分倒装的,但是应该是neither/nor各自引导的句子都得部分倒装。所以应该是:
Neither do the foods need providing good service, nor do they have to be sent immediately. therefore....。
楼上几个忽略的是have to中的have是实义动词,不可以做is, do, will一样前置的,除非这里的have是完成时态中的have.
1. because not only does it...
2. 对。
1 because not only
2 right
