48.Digging in sediments in northern China, scientists have gathered evidence suggesting that complex life-forms emerged much earlier than previously thought.
62. Laos has a land area comparable to that of Great Britain but a population of only four million people, many of whom are members of hill tribes ensconced in the virtually inaccessible mountain valleys of the north.
111.According to recent studies comparing the nutritional value of meat from wild animals and meat from domesticated animals, wild animals have less total fat than livestock fed on grain and more of a kind of fat thought to be good for cardiac health.
最近在总结比较问题的题目发现了一些个人比较模糊的地方，上面的划线部分已经是正确的选项。
在这些比较对象里，有些是严格的逻辑对应，但是有些是相对于不是符合逻辑，比如，62，Laos has a land area comparable to that of Great Britain，that指代 land area，但是在111. wild animals have less total fat than livestock ,并没有写成wild animal have less total fat that total fat of livestock。
所以在处理此类问题上一直很模糊，想请教一下大家是怎么考虑的。

62.里面比较的是land area，因为comparable to that of Great Britain是修饰land area，也就是说老挝有这么一块领土，这个领土和大英帝国的领土差不多；111.里面比较的是have这个动作，意思是野生动物拥有的脂肪比家畜拥有的脂肪要少，这里面livestock后边省略了have，如果改成wild animal have less total fat than total fat of livestock，意思就是野生动物拥有的脂肪比家畜脂肪拥有的脂肪还少，意思就不对了。这种比较的问题，我觉得最好就是从语义出发，翻译成中文的话就很容易看出对错。作者: xsq805 时间: 2017-11-3 17:58
我觉得主要是考虑两点，
1）比较对象是主语，谓语动词，还是宾语什么的，比如，62)比较的是宾语 land area，为了比较对等，后面要加that of；111）比较的是主语 wild anmials 和 livestock，这两者本就对等都是动物，所以不用重复。
2) comparative marker 的用法，比如 62）也可以比较主语，如： Laos has the same land area as Great Britain.
