Question

不定式做定语放在所修饰的名词后,表示在谓语动词之后发生的动作或过去的某一特定动作.
He had no house to live in but a lot of work to do. 他没有房子住却有好多活要干.
Our monitor is the first to arrive. 我们班长是第一个到的.
请问以上例子里为何要加to do ?请详细说明.

Answer 1

其实只是语序理解的问题,可以把语序动一下,就好理解了
He had no house to live in but a lot of work to do.
=He had no house to live in but he had to do a lot of work.
a lot of work 在这里做do 的直接宾语
Our monitor is the first to arrive
= The first to arrive is our monitor.
to arrive 这里做主语the monitor 的修饰词
