英语改错,急!每天都有哦!第一个You should encouragement him to it.第二个It's s

You should encourage him to it因为这里encouragement是名词,这里需要的是动词,所以把名词改为动词就好了.
It's sad of him and equal.在It's的用法中,如果这个形容词主要修饰是人,用of,修饰的是一件事,就用for.
比如：
It's kind of you!你真好,这个很明显是修饰人,一般这种词关于人的喜怒哀乐好坏的都用of.
It's importent for you to study hard.这里是说努力学习这件事很重要

ARTIFICIAL INTELLIGENCE, which he took up at the encouragement of the score is among his most impressive. I listened to it on CD for three

第一个应该是You should encourage him to do it.句型为encourage sb to do sth.第二个是It is sad and equal for him.句型是it is+形容词for sb to do sth.
