你没注意到,这两个句子之间是什么符号吗?
很明显是逗号,表示这两个句子是同属于一句话,既然是这样,我们都知道正常的一句话,只能有一个主语,一个谓语,一个宾语.而前半句话已经同时出现主语,谓语,宾语了.所以后半句话要想与前一句同时存在,就只能作为从句出现了.而后半句其实修饰的就是前半句的animal.两个句子用一个引导词which连接.
把后半句单独拿出来分析,some of the animals have almost die,them是代词,用them相当于就是直接用animal了,那么显然这个句子也是个完整的具有主语谓语的句子了.要想存在,只能和前一句分开,必须把两个句子间的逗号改成句号.或者在两句话间加上一个连词,比如and.
总之用which和用them最大的区别就在于,前者是一个句子,后者则是两个句子

定语从句,some of which 修饰animals
如果是This would save the life of many animals,and _____ have almost die.这时用some of them

定语从句,some of which 修饰animals
