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。

work (hard) at: 努力学习，work on：继续工作；work out：想出计算出，制订；at work (on ): (人)在工作，从事于……，忙于……，比如：
① English is so important that we must work hard at it.
② It was very late , but he was still working on without supper.

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。
分词有两种，一种是现在分词，一种是过去分词。这两种分词在句子中能担任的成分大体相同，主要是在意思上有主动和被动之分。现在分词一般有主动的意思，过去分词一般有被动的意思，有时表示的时间也不相同。试看两种分词的主要差别。如：
He is a promising young man. 他是一个很有培养前途的青年。
This is a pressing problem. 这是个紧急问题。
He is an interesting man. 他是个有趣的人。
He's very interested in the man. 他对那个男人非常感兴趣。

We were excited to hear it. 听了这事我们很激动。
