题目

答案
两个that引导的是定语从句,引导词分别是animals和those,两个引导词在从句中都是主语,句子构成是这样的:
Animals (that could not adapt themselves to the environment) perished and those (that could)survived.
第一个括号里是animals的定语,意思是:(那些不能适应环境的)动物;
第二个括号完整的应该是that could adapt themselves to the environment,是those(代指animals)的定语,意思是:(那些能适应环境的)动物;
整句话直译的话是“不能适应环境的物种遭到灭绝,能适应环境的得以存活.”
其实就是“物竞天择,适者生存”的意思.
