我觉得哦

D,E无that 错

B 从句中 主语是the metabolism +were 复数 错

C前面同B ，且those of mammal's重复啦

A没有错

首先由于是宾语从句 所以用that表示完整概念和简洁性 所以排除D E； 之后由于双重所有格 而且those容易引起就近指代species的歧义很不好 排除C； 所以这道题相对不好排除的是B 首先是主谓不一致像楼上说的； 第二点不是很主要 不过用of的所有格的话不能够很好的和后面的warm-blooded mammal’s 和cold-blooded reptile’s并列但是即使并列也没错 第三改变了原文的强调对象将原文助于位置的species had变为了介词短语的位置 很不好 所以A正确
