Unit 18 Seeing the doctor

2005年5月17日 来源:网友提供 作者:未知 字体:[ ]

  在阅读开始之前,老师可以提几个简单的问题,如:Do you often dream?What do you usually do when you dream? /Would you like to know something about Roy’s dream?学生对阅读的兴趣,增强他们急于了解课文内容的迫切心情。同时为了减少学生阅读的难度,可以先列出一些估计学生比较难于理解的词汇、短语或句子。如:as soon as, be busy doing sth., terrible storm, stop the ship from going down .sleeping pills, be awake, fall asleep, relax, Don't they work? light music等。阅读完以后让学生做练习册中第70课的练习一,看看他们是否已经理解了课文的内容。
  第72课的阅读短文讲的是一个胖女士请医生看病的故事。在组织学生阅读前老师首先问学生第一个问题:Is the woman fat or thin?然后问第二个问题:Why did the woman go to see the doctor?让学生围绕这些问题去阅读。等学生阅读完以后,老师可以用一些最简单的一般问句问学生,例如:Is the woman feeling very well?/Did the woman have to sit down and rest every five minutes when she worked yesterday?等。然后让学生听录音,加深印象。最后,教师可以让学生做课文改写以后的填空练习。这样能使阅读、听力、书面训练有机地结合在一起,使教学效果更趋于完美。
语法教学
  1.情态动词have to
  (l)情态动词have to和must在意义上基本相同,在很多情况下二者可以互换使用。但must是强调说话人的主观看法,而have to强调的是客观需要。从形式上看must适用于所有的人称,没有时态的变化;而have to有第三人称单数has to,还有时态的变化:had to(过去时),will have to(一般现在将来时)等。例如:
  ①There must be some students in the classroom now.
  ②We must learn English well.
  ③He must stay at home and look after his brother.
  ④There is no bus, we have to go to school on foot.
  ⑤Lucy’s mother is ill in hospital, she has to look after her.
  ⑥She couldn’t find her pen, she had to buy a new one.
  ⑦The students will have to know how to use the computers.
  (2)含有情态动词have to的各种句型
  ①陈述句
  I/We/You/They have to/had to. . . .
  take this medicine three times a day
  clean the classroom once a day
  ②主语是第三人称单数

  教师可通过两人一组的形式操练有关内容,最后叫几个小组到教室前面表演。
  2.系动词
  系动词本身有一定的词义,但不能独立作谓语,必须和后面的由名词(短语)、形容词(短语)副词或介词短语构成的表语一起使用。最常用的系动词是be,另外还有look,become,get,seem,turn,grow,take,feel,soled,small筹。如:
