32. As do all insects, a butterfly has a hard outer covering, called it an exoskeleton, that both supports and protects the body.

想知道，为什么用as do all,这里什么意思呢？？

one of the inversion structures

我还是不明白啊

麻烦你再给解释下

as   可以引导倒装

1，Megumi is from Japan,as is Sato.

2,So-eun wants to leave early today,as does Oi.

3,As  do I , my mom likes this restaurant too.

我觉着主要是考do和has的对应关系。

has在句子中是实意动词，“拥有”，所以是一般现在时，因此对应到all insects应该用do。用下面这个对话是不是好理解一些？

-I have an apple.

-So do I.
