protect sb from doing sth这里的from不能省略。
protect...from…是表示保护。。。不受伤害。from后接能带来伤害或损害之物。
所以是:
Protect sb/sth from sth/doing sth
例句:
You had better wear sunglasses to protect your eyes from the sun.
Hair can protect our heads from being hurt.
注意:
prevent sb from doing sth与stop sb fromdoing sth用法相同,在主动语态中from可以省略,被动语态中不行。keep...from在表示此意时,from不可以省略。keep。。。doing 是使。。处在。。状态中的意思。如果没有了from就变成了keep sb doing sth了,意思就反过来了。

prevent sb from doing的from可以省略。 prevent ...from ...表示“阻止某人(某物)干某事”, 介词from后常接动词-ing形式。用于主动语态时,prevent sb. / sth. from doing sth. 中的from常可省略,用于被动语态时,三者中的from都不能省略。例如:
1. The bad cold prevented / stopped Alice ( from ) taking part in the sportsmeet.
2. The old lady can’t bepreventedkept from joining the club.
1. The bad cold prevented / stopped Alice ( from ) taking part in the sportsmeet.

这里的from可以省略
表示“阻止……做某事”有三种表达方式,其中prevent/stop sb from doing sth 中的from可以省略(主动语态中可省,被动语态不行),keep sb from doing sth中的from不能省,如
Nothing could prevent me (from) working hard.
没有什么能阻止我努力工作。
The heavy rain prevented/stopped them (from) going out. = The heavy rain kept them from going out.
大雨使得他们不能外出。
