句中a doctor for an animals 可以用an animal doctor 的形式表示。如：
He is a famous animal doctor from England. 他是来自英国的著名兽医。
2. To be a doctor for animals is very rewarding. 当兽医很值得。

4. To help animals is helping people. 帮助动物就是帮助人类。
句中helping是现在分词作定语，修饰people。

第58课重点例句及相关知识的分析
1. There is a famous animal doctor from England who wrote many books about animals. 一位英国著名兽医，他写了许多关于动物方面的书。
句中from England 介词短语做定语，和who wrote many books about animals 从句做定语同时修饰doctor。
2. He grew up with a pet dog named Don. 他与被叫Don 的爱犬一起长大。
句中named 是过去分词做定语，修饰dog。
named 相当于called 或with the name，意思是"被叫做……"

The boy with the name John is my classmate. 叫约翰的那个男孩是我的同学。
3. He made up his mind to be a vet．他下定决心要成为一名兽医。
make up ones mind是"下定决心"的意思，其后常接不定式。ones必须和其相应的主语保持一致。如果主语为复数，mind也要用复数形式。如：
（1）Ive made up my mind．我已决定了。
（2）He needs someone to make up his mind for him．他需要别人替他作决定。
（3）The students in Class 1 all made their minds to study hard．一班的全体同学都下定了决心要努力学习。

第60课重点例句及相关知识的分析
1. Mrs Parley said she felt as if they were in a storm at sea. 帕利太太说她觉得好象是在海上乘船遇到了风暴似的。
句中as if 相当于as though "仿佛……似",注意：当主句是一般现在时，as if从句用一般过去时；当主句是一般过去时，as if从句用表示过去的相应时态。如：
He speaks English as if he were an Englishman. 他说起英语来好像一个英国人似的。
He acted as if （as though） nothing had happened. 他表现得似乎没有发生什么事。
She loves the child as if he were here own. 她爱这孩子如同爱自己的孩子一样。
此外，as if （as though）后可以跟动词不定式。如：
She raised her hand as though （as if） to hang the picture on the wall. 她举手象要把这幅画挂在墙上。
He raised his hand as though to take off his hat. 他举起手来，像要脱帽似的。

由dropping 和leaving 组成的两个-ing形式短语在句中作伴随情况状语。如：
They came into the room laughing and talking. 他们说说笑笑地走进屋来。
Taking a dictionary, she began to prepare her lessons. 她拿了本词典，开始准备功课。
3. …… just as the bed crashed to the first floor ……与此同时床坠落到了一楼。
4. It is true to say a dog is mans best friend or at least Roberts best friend. 事实上说狗是人类最好的朋友，起码是罗特的最好的朋友。
* 句中it是形式主语，to say a dog动词不定式是真实主语。
句中it作先行代词用。It在句中充当形式主语或形式宾语，而将真正的和逻辑上的主语或宾语（通常用不定式短语、动名词短语或从句表示）移到后面去。如：
It is very important for us to learn English. （it代替不定式to learn English做形式主语）我们学习英语是十分重要的。
It takes much time to carry out a test. （it 代替不定式to carry out a test作形式主语）进行试验是要花费许多时间的。
