同学你好，
away from是一个介词结构，所以一般跟在动词或系动词后，不能直接加在形容词后哦，所以这句应该为：He is unsociable and keeps away from people.
动词或系动词+away from搭配的有很多哦，例如：keep/ stay/ be/ walk/turn away from等等
1.She's been away from home for many years.
她离家已经多年了。
2.He walked away from his car
他从自己的车边走开了。
3.The car turned away from the coast and headed inland.
汽车离开了海岸，驶向内陆。
4.Both of my sisters moved even farther away from home
我的两个姐姐都搬得离家更远了。
祝学习愉快！
