Question

帮忙翻译并语法分析下这个英文句子吧，多谢多谢

And it was obvious that the underfed white mice, in the process of searching for their food, had kept healthy by exercising in finding food, being adaptable, and improving their immunity.

Answer 1

这句话就是一个主语从句：it 为形式主语 真实主语是that引导的从句
主语从句里的 主语是 the underfed white mice 谓语是 had kept healthy 这句话就是状语较多
1. “in the process of searching for their food ” 介词 in 加上名词 the process 构成了介词短语做状语of searching 也是介词短语修饰 process这个名词 由于 search 要跟 for搭配表示 搜寻 找寻 的意思所以后面很自然的加上了 它的宾语 their food
2. “by exercising in finding food “ 介词 by 加上动词ing构成的方式状语
3. being adaptable, and improving their immunity. 用 and 连接两个 现在分词所作的伴随状语
这句话的意思大致是：而且很明显，这些半饥半饱的白老鼠们在搜寻食物的过程中已经通过在找食物时得到的锻炼保持了健康，更加适应环境也提高了它们的免疫力。

Answer 2

And it was obvious that the underfed white mice, in the process of searching for their food, had kept healthy by exercising in finding food, being adaptable, and improving their immunity.
很显然，在寻找食物的过程中，这些小白鼠虽然食不果腹却能保持健康，得益于觅食中的运动，得益于不断适应，得益于不断提高免疫力。
把句子转换一下，可以看得明白一些：
By exercising in finding food, being adaptable, and improving their immunity, the underfed white mice had kept healthy in the process of searching for their food.
by：通过，由于...
exercising..., being..., and improving...三者并列，共同发挥作用。

Answer 3

貌似underfed应该是underfeed
这句话的大致意思就是：同时，实验结果也很明显，没有吃饱的白鼠由于处在寻找食物的过程中，一活动使得它们保持着健康。也变得适应环境，免疫力也有所提高。

Answer 4

很明显，吃不饱的白老鼠，在这个过程中寻找食物，保持健康的运动中寻找食物，是适应，并提高其免疫力。

Answer 5

很明显，在寻找食物的过程中，通过身体得以锻炼，变得更加适应环境以及提高它们的的免疫力，那些食不果腹的小白鼠已经保持了健康．
首先it在这里是一个形式主语，其次真正的主干是主谓宾，即：the mice had kept healthy.而in the process of searching for their food是插入语； by exercising in finding food, being adaptable, and improving their immunity是方式状语。翻译时，先翻译状语，定语，然后才是主谓宾。
