八、教学过程
1.新课导入(5分钟)
(1)在一如既往向学生问好时,添加比较句:How are you? 待学生回答
后,继续问“Do you feel today is better than yesterday?”。趁学生疑问之际,将句子写到黑板上,略作简单讲解“better是good的比较级,‘更好’的意思,than用于比较句中‘更……’的意思,这句话就是‘你觉得今天比昨天更好吗?’。”引发学生兴趣,引出讲课主题。
(2)放一首歌词中反复出现比较级的歌曲《longer》,并展示歌词,粗略
的讲解“形容词原型+er”表示比较级“更……”,教师简单翻译歌词内容,让学生对比较级用法有个感性认识。beautiful girls歌词
2.新课讲授
(1)首先讲单词和词组(20分钟)
教师讲解,同时配合学生造句,以加强教学效果。
1glory: ['ɡlɔ:ri]  n.光荣、荣誉、赞颂;vi.自豪、骄傲、狂喜
例句:Walsham had his moment of glory when he won a 20km race.
沃尔沙姆有过赢得20公里赛跑的光荣时刻。
Their father gloried in their success.
他们的父亲为他们的成功而自豪。
2marry: ['mæri] vt. 嫁;娶;与……结婚
例句:He married a beautiful girl.
他娶了一个漂亮的姑娘。
【注意在英语中“嫁”和“娶”都是一个词,都是marry。同时不能用中文的思维将“marry与“with搭配,“嫁给某人”和“娶某人”直接说“marry sb”。同时,marry常用于被动,作“使结婚”讲。例如:
They are going to be married last month.
他们下个月就要结婚了。
   
3bargain: ['bɑ:ɡin] v.讨价还价 
bargain with sb 与某人讨价还价
bargain over  在……上讨价还价
例句:We refuse to bargain over the price.
我们拒绝在价格上讨价还价。
【注意】bargain还常用作名词,作为“便宜货,特价商品”之意。例如:At this price the wine is a bargain.
以这个价格,这葡萄酒算是物美价廉了。
4asas :“与……一样”,常用结构“as+形容词/副词原形+as+分句”
例句:I will reply it as soon as possible.
我会尽快回复的。
He cant draw pictures as well as Lily does.
他画画没有莉莉画得好。
(2)疏通课文(20分钟)
1先让学生默读课文(2分钟),之后放录音,一句一句跟读。
23分钟小组讨论(教师同时走到学生中间,有问题随时提问)。随后让学生轮流逐句翻译课
文。
3根据学生提问及翻译情况,教师提出比较困难的句子再进行分析和讲解。例如:But she was not allowed to run and win glory for herself in the Olympic Games. 主句是she was not allowed,“她不被允许”,“不被允许run和 win glory ,在奥运会上为她自己run和 win glory”,run 和win glory是 not allowed to 后的并列成分。
(3)语法讲解(65分钟)
1本课文中出现多次比较句。先将课文中所有带有比较级的句子提出:
She could run faster than any man in Greece.
She would not marry anyone who could not run faster than her.
The race started and although the man ran very fast, Atlanta ran faster.
让学生通过翻译句子的意义和揣摩这几句话的结构,自己提出对“比较句”的结构意义的等的小结,同时教师会做出判断和点评。
2系统讲解“比较句”
A.同级比较as…as结构, 具体在句子中,就有两种应用形式:
A is as +adj as B 或者:A do B as + adv + as C (do).
例句:Mary is as tall as Betty.
I drove as carefully as Tom did.
否定式:A is not as/so + adj + as B;或 A do not do B so/as + adv + as C (do).
例句:Mary is not so tall as Betty.
  I did not drive as carefully as Tom did.
B.比较级:morethan结构,具体在句子中,就有两种应用形式:
A is er than B( A is more + adj原级 + than B),或者: 
A do B er than C (A do B more +adv原级 + than C.)
例句:Mary is taller than Betty.
      Mary is more beautiful than Betty.
      Mary studies harder than Betty.
I drove more carefully than Tom did.
否定式:A is noter than B( A is not more + adj原级 + than B) 或者A dont do B er than C (A dont do B more +adv原级 + than C.).
例句:Mary is not more beautiful than Betty.
Mary does not study harder than Betty.
注意】 这里可以用lessthan来表示morethan的反义,但less…than 听起来不够地道,用asas或morethan更加普通。例如:
Mary is less beautiful than Betty.
= Mary is not as beautiful as Betty.
= Betty is more beautiful than Mary.
注意】在形容词/副词的比较级前,常用一些副词修饰语修饰,表程度更轻或更甚。
程度稍轻——a little, a bit,slightly,
程度更甚——a lot, even, far, many, much, rather例如:
Mary is even more beautiful than Betty.
      There are many more students in our class than in theirs.
      I have much more money than he has.
C.最高级
最高级:the most结构,具体在句子中,就有两种应用形式:
  A is the est +比较范围. (A is the most + adj原级+比较范围) 或者: 
  A do B theest +比较范围. (A do B the most + adj原级+比较范围)
