Do you like being a doctor for animals? 您喜欢当兽医吗？句中的being 可以用to be 的形式表示。如：I like to be an English teacher. 我喜欢当一名英语教师。句中a doctor for an animals 可以用an
26、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。句中rewarding是形容词，意思是”有报酬的；有用的；有益的”。如：You will find this book very rewarding. 你将发现这本书是非常有益的。3. Id like to work with animals better.相比人类而言我更喜欢为动物服务。work (hard) at: 努力学习，w
27、ork 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： English is so important that we must work hard at it. It was very late , but he was still working on without supper. He has already worked out these maths problems , so he feels very happy.4. To help animals is helping people. 帮助动物就是帮助人类
28、。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。Hes very interested in the man. 他对那个男人非常感兴趣。The n
29、ews is exciting. 这消息很激动人心。We were excited to hear it. 听了这事我们很激动。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
30、. 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 called John is my classmate. =The boy named John is my classmate. =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
31、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。 4. They regarded their pets as members of their families. 他们把宠物视为家庭成员。句中regard as意思是”将视为”。如：I regard him as my brother. 我
