组织学生进行对话如下: Lan Lan’s father: Hello! Lan Lan’s teacher: Hello!Are you Lan Lan’s father? Lan Lan’s father: Yes, I am. Lan Lan’s teacher: I am Lan Lan’s teacher. Lan Lan’s father: Glad to meet you. Lan Lan’s teacher: Glad to meet you too. Lan Lan’s father: Can you tell me something about Lan Lan? Lan Lan’s teacher: Ok. Lan Lan’s father: Did Lan Lan often forget her homework? Lan Lan’s teacher: Yes. But not now. She always finishes her homework on time. Lan Lan’s father: Was she often late for school? Lan Lan’s teacher: Yes, she did in the past. but now she never gets to school late. Lan Lan’s father: Is she still careless? Lan Lan’s teacher: No, she studies harder than before. (2)教师可以组织学生按照课文进行角色表演。 (3)课本的第二部分主要是讲解there be结构过去时态的陈述句，疑问句及否定句形式，教师可以将它改编成一段记叙文。如下： There were four singers in the band last year. There were also some women in it. But there was a problem at that time. One of the singers wasn’t good. People didn’t like her. There are three singers now. There isn’t a problem any more. 笔头训练建议 要求学生能讲述一个自己所经历的故事，教师可以设计一个开头，如：It was Sunday yesterday. I went to the park with my classmate. It was very hot. On my way to the park I saw an old man walk along the street. Suddenly, he fell down the street 让学生自由完成后续部分。 根据阅读课文My father来写一篇介绍学生家庭成员(grandmother/ grandfather)的文章。让学生先就课文所提示的问题向他们的祖父母进行调查，这些问题涉及到他们的出生年代，所受教育，婚姻、子女及工作状况。然后分小组对各人所了解的情况进行讨论，以便互相补充和启发。 关于there be结构的一般过去时的建议 教师在引入时应使用比较法让学生自己比较下列句子的区别，总结出两种时态在意义上和在结构上的区别。 (1)There is a book on the desk. There was a book on the desk a moment ago. (2)There are some apples in the bag. There were some apples on in the bag yesterday. 然后教师在使用实物教学使学生完全掌握此结构。例如教师在桌上放一些实物问What is / are there on the desk? 学生根据实际情况答There is / are …on it. 教师还可问Is there…? Are there…? How many …are there? 并把这些问题写在黑板上。问答完毕，教师可把桌上的东西收起来，然后问：What was there on the desk a moment ago? Was there…? Were there…? How many …were there? 等问题，可帮助学生回答。 There be 结构与have / has 在英语里表示“什么地方或时间存在什么事物或人”时，要用there be结构。在此结构里，there 是引导词，本身没有词意，be是谓语动词，be后的名词是主语，主、谓语的数必须一致，句子的结尾是地点或时间状语。如： There is a ruler on the desk. There are many students on the playground. 在使用这个结构时应注意以下几点： 1. there be结构变成否定式时，须在动词be后加not(a / any)或no。变成疑问句时，将be放在there之前，句中如有助动词时要把助动词放在there之前，句子其余部分不变。如： There aren’t any pencils in the pencil-box. There are no pencils in the pencil-box. Is there any milk in the bottle? Will there be a meeting next week. 2. there be结构有两个并列主语时，要根据就近的主语原则确定谓语是单数还是复数。如： There is a boy and two girls in the picture. There are two girls and a boy in the picture. 3. There be 结构中的be可有不同的时态，而且可以和各种助动词和情态动词连用。如： There is going to be a sports meeting in our school in May. There must have been an accident there. (现在完成时，以后我们会学到的)。 4. there be结构中的谓语动词be，有时可用seem to be, happen to be, used to be, stand, live等词或词组来代替。如： Once upon a time, there lived in Greece a great thinker named Aristotle. 从前在希腊居住着一位名叫亚里斯多德的伟大思想家。 There seems to be something wrong with you. There stands a tall tower in the middle of the square. 在广场中央竖立着一座高塔。 5. 注意there be 结构与have / has 的区别。there be表示“存在有”，而have / has 则强调人或物体本身“具有”(has 只用于第三人称单数)。如： My sister has many toys. China has a long history. We have a lot of friends. have / has变成否定式时，应在其后加not或借助于助动词don’t或doesn’t;变成疑问句时，将have / has提在主语前或借助于助动词do或does放在主语前。如： I have not a bottle of orange. I don’t have a bottle of orange. Do you have a red pen? Have you a red pen? 注：I have no Chinese car. = I don’t have a Chinese car. (责任编辑：admin) |
