问题描述：
prevent...from protect...from
Dinosaurs had few natural enemies besides each other,so each species had to _____ their young from being eaten by other dinosaurs.
Sadly it became hot and dry and the dinosaurs were unable to _________themselves from disappearing altogether.
选填prevent protect
我觉得第一句两个都可以啊
答
protect有保护的意思，prevent有阻止的意思，
第一句用protect比较恰当
答
prevent from一般是通过对宾语(这里是their young)自身采取措施,来防止其遭受某种损害.
后者则主要表示对加害方采取措施以防止宾语受到损害.
这就是两者的区别所在.
