A doctor for animals

　　It takes them several days to build a nest. They have to work in the early morning. The swallow lays five or six eggs at a time. The mother bird sits on them, and the father bird watches by her side and gives some food to her.

　　You must not think that when swallows fly over your head, they aren't working. No! Life is work to them. The young swallows eat a lot and they are busy catching the insects for them. So they have to work from early morning till late at night. At last the young birds can fly well, but the old ones can't rest. They began to think about their second family, for they have two broods every season.

　　When the second brood can fly, too, it's time to think about going to the warmer countries, and when spring comes, they'll return.

教学建议（二）

关于写作训练的教学建议

　　本单元第60课的第4项是写作训练。主要是叙述父母的职业。根据本单元关于动物的主题，这里建议写作内容可选择以动物为主题。

　　动物是人类的朋友，我们应当爱惜它们。人与动物和平相处，世界会变得更加美好。由于近几年保护动物的呼声日益高涨，各国各地区分别开辟和划分大片土地作为野生动物园，从此，野生动物有了属于自己的家园，动物的数量和种类都相应增加。为了便于人们观赏海洋动物，了解海底世界，海洋馆也应运而生。

　　请就此题材写一篇短文，描写你参观海洋馆的情况，及个人对此的感受。

[分析与引导]

　　此篇短文类似于游记，要求写出时间、地点、人物、事件、经过和观后感受。应按照时间的先后顺序写，内容要详略得当，突出重点，特别是在“人与自然”这方面应有所体现，尽力表达人与动物和平共处的和谐之美，使读者有身临其境之感，引起共鸣。

[范文与点评]

　　A visit to the world under the sea

　　Have you ever been to the world under the sea ? I have been there once.

　　It was a sunny morning. I with my father went there on a bus. It was a little far from my home. It took us about two hours to get there. After getting the tickets, we went in.

　　First, we went into a large hall. There I saw a pond with several dolphins. We were told that there would be a performance in ten minutes, so we found a good place for watching. Soon a beautiful girl came out and the performance began. The dolphins performed very well and all the people there watched carefully and such words as Wonderful, Great, Good, Cool could be heard again and again.

　　Then, we came to the touching pool. There were some small fish in it and visitors could touched them with their hands softly. And the girl working there explained their names to us. It was not easy to touch them in my life , so I played there for a long time. It was very interesting.

　　At last, when it was nearly the lunch time, it was the time for another performance of all kinds of fish and a diver. At this time many fish came here for their lunch and the diver gave them their food. The diver was a young beautiful girl and she said Hello to us with her hands. It was difficult for her to feed the fish because some of them were dangerous, especially sharks. I was worried about her all the time, but the girl did it easily and well. We could see that she had become a good friend of sharks and many other animals. We felt very excited and thanked her a lot.

　　It was a good visit and it was a good lesson for me, too. People and animals are good friends and we should live together well. I should learn from the girl feeling fish. Nothing is too difficult if we put our hearts into it. If we have a great goal, we should try to do it well and we will be the winners.

　　本文符合游记的要求，时间、地点、人物、事件及其先后顺序和教益都交代的很好，特别是“人鲨共舞”场面的描写很精彩，充分体现了“人与自然和谐相处”这一主题思想，读后能使人引起共鸣，达到了教育的目的。

第57与59课对话及不定式做主语的教学建议

　　57课是以为狗看病为话题的对话，从一对父子的谈话中，可以看出作为兽医的父亲对自己的职业的热爱，以及对动物与人之间关系的理解。并引出了不定式作主语的用法。59课是母子谈论医生这一职业的对话，引出了it作为形式主语的不定式结构。

　　建议这两课的教学过程有机结合，巧妙地安排授课时间，完成这部分内容的学习。先让同学们对这两课内容一起预习，主要是熟悉生词和语法。上课时，围绕着职业的谈论展开，引出相关的教材内容，再反复练习不定式作主语的句型。

　　可以先引导谈论他们将来想选择的职业，提出问题：

　　What kinds of jobs do you know?

　　What would you like to be in the future?

　　What are your parents' job?　

　　Do your parents like their job? Why or why not?

　　在适当的情况下提示学生一些职业的说法。对有些职业的名称可参考下文提供的《关于职业的英语词汇》。

　　然后让学生熟悉对话的内容，如通过放录音、看影片、或阅读教材来实现。再进一步对不定式作主语的句子进行分析：

　　To be a doctor for animals is very rewarding.

　　To help animals is helping people.

　　To do what the doctor tells you is important.

　　可以将以上两句与下句进行比较，突出不定式是怎样作为主语出现的：

　　To many people, a pet is like one of the fam
