We can learn about(A) our bodies and why they look (B)and work the way (c) they are(D).

learn about(A)
why they look (B)
the way (c)
they are(D)

为什么d是错的?详细地讲解一下!!

请看完整句子:
We can learn about our bodies and why they look and work the way they do.

这里A是了解,知道的意思。B中的look是看上去的样子,work是他们工作起来。why后面想说的意思是他们为什么是这样的。由于前面是实义动词,我们就要用do来代替前面的两个动作。所以不能使用they are。

确实是they do

they do 因为前面是they look and work, do 代替了look and work,
再看一句:
They know why we are the way we are.

look ,work是实意动词,应用do而不是are
