Question

求高手解释一个英语句子的意思！

The first thing you want to do is understand why you want to exercise.

这句话是不是错的？is 后面是不是应该要有to understand ??

Answer 1

is 和 understand 出现两个动词就错了，所以把understand改成不定式，前面加个to

另外you want to do 改成you should do，客观的“要”是should，主观的“要”可以用want

做运动用一般用do exercise

The first thing you should do is to understand why you want to do exercise.
你首先得做的是明白你为什么要锻炼。

Answer 2

应该加to 的
你最想做的事是理解你为什么想要锻炼。

Answer 3

我觉得是understanding呢。。。。
因为他作表语啊
