protect do sth对吗对的，保护某人去做某事。当然，这里的to应当是不定式，表目的状语从句。protect 是用最多的固定搭配，保护某人免受伤害，from是介词。
如：They protect her to fight against the battle.他们为保护她而去参战。to fight against the battle是不定式表目的。
protect do sth对吗
正确的短语应该是protect sb from doing sth（保护某人以免遭受…）。如：Sunglasses can protect our eyes from being harmed. 注意本短语与prevent sb from doing sth（阻止某人做…）的区别。如：The heavy rain prevented me from going to school on time.意思相同的短语还有：stop sb from doing sth，keep sb from doing sth。
