1、教学设计 课课 题题 Unit2 Exploring English Using language（1） 学学 科科 英语英语 班班 级级 Class 授课授课 教师教师 教教 学学 目目 标标 1 带领学生复习英语中常见的构词法，使学生能够根据构词规律推断词义、进行单 词重构； 2 引导学生初步了解并说明英式英语和美式英语在拼写方式、 词汇使用方面的差异， 开阔国际视野； 重重 点点 认识四种不同的构词法 难难 点点 介绍美式英语和英式英语在拼写方式和词汇使用方面的差异，帮助学生了解这两种 英语的特点 教教 学学 方方 法法 Teach grammar in real situations.

2、 Learn grammar through practice. 教教 学学 内内 容容 与与 过过 程程 Step1 Review: word formation 第一步：请学生朗读学生用书中的四个例子，关注粗体部分。学生以小组为 单位，讨论活动中呈现的构词法，完成粗体部分的单词与相应构词法的匹 配。 Look at the sentences and expressions from the reading passage. Match the words in bold to the types of word formation. a . Neither is there pine n

3、or apple in pineapple. b. sculpt a sculpture c . When we see rain, we can say “its raining” d . WHO 1. abbreviating 2. changing the part of speech 3. adding a prefix or suffix 4 .combining two or more words 备注备注 第二步：请学生在课文中找出涉及本活动中构词法的更多例子，进一步体会 其表意功能，学会根据构词规律推断词义。 Now look for more examples of each

4、 type in the reading passage. 参考答案 1d 2c 3b 4a More examples in the reading passage: abbreviating: IT, US changing the part of speech: When we see snow, we can say “its snowing”. adding a prefix or suffix: paint painting, hard hardly, soft softly, harm harmless / harmful, shame shameless / shameful,

5、 visible invisible combining two or more words: hamburger, eggplant, seasick, airsick, carsick, homesick, homework, housework Step2 Presenting 构词法讲解构词法讲解 1. 合成法：把两个或两个以上的独立且语义不同的单词合成一个新词， 构词方式较灵活。合成词的词义通常可以由组成它的单词的词义推测出 来。 1）合成名词 news + paper = newspaper hair + cut = haircut 2）合成动词 baby + sit = baby

6、sit over + look = overlook 3）合成形容词 heart + felt = heartfelt kind + hearted = kind-hearted 4）其他合成词 every + one = everyone through + out = throughout 2. 派生法：在词根上加前缀或后缀，构成新词。前缀和后缀有一定的含 义或功能，有助于推测新词的词义。 一些常见的前缀、后缀及其含义或功能如下。 3. 转化法：把一种词性转化为另一种词性，词形不变。转化后的词义可 以通过原词义推断得出。 1）动词转化为名词 Lets talk about it. 咱们谈谈

7、这件事吧。 I think wed better finish the talk now. 我想我们现在最好结束谈话。 2）名词转化为动词 She gave me a glass of water. 她给了我一杯水。 You should water the flowers twice a week. 你应该每周给这些花浇两次 水。 3）形容词转化为名词 She is wearing a black dress. 她穿着一条黑色的裙子。 The girl in black is very beautiful. 那个穿黑衣服的女孩很漂亮。 4）形容词转化为动词 Tom is a brave ma

8、n. 汤姆是一个勇敢的人。 He always braves the difficulties in life. 他一直勇敢地面对生活中的困难。 4 缩写：用单词或短语的部分内容指代整体。 1）首字母缩写 ASAP as soon as possible WTO World Trade Organization 2）单词截短 advertisement ad laboratory lab Step3 Consolidation 教师带领学生进一步了解英语构词法的内容及例子， 在真实语境中巩固对英 语构词法的理解。 第一步：学生独立阅读活动中的语篇，整体理解语篇大意。 第二步：学生以小组为单位，

9、运用构词法的表意功能，根据上下文，用括 号中的信息完成填空。 第三步：请个别学生朗读完整语篇，全班核对答案。 Complete the passage with the help of word formation. When you open a dictionary, you often come across a lot of unfamiliar words. You might think this is a bit scary. But many of them are formed using other simpler words. This is called word fo

10、rmation. Words formed by combining other words are called compounds, for example,1_ (a friend that you contact by writing, traditionally using a pen) and 2_ (known by many people). Prefixes and suffixes often have fixed meanings. If you add un- or in- to a word, the new word usually means the opposi

11、te. For example, if something isn t correct it s 3_ , and if someone isn t happy they re 4_ . Words with the suffixes -ment and -ness are often nouns.For example, if somebody has improved a lot, they have made great 5_ . Some nouns and adjectives can be used as verbs, or the other way round. When we

12、 calm somebody down, they become 6_ . And we can give someone a present by 7_it.And sometimes a word is made up of the first letters of several words: “World Trade Organization” can be referred to as 8_ , and 9_ is short for “as soon as possible”. It is impossible to know the meaning of every word,

13、but knowing about word formation can help us guess their meanings. 参考答案 1 penfriend 2 well-known 3 incorrect 4 unhappy 5 improvement 6 calm 7 presenting 8 WTO 9 ASAP Step4 Practice 教师带领学生通过游戏应用构词法，并进行创新迁移，引导学生自行发现更 多符合构词法的单词，实现课堂的活动性和实践性。 第一步：将学生分组并带领学生了解游戏规则。 第二步：为各小组随机分配一种构词法，分到同一种构词法的小组间进行 比赛，能说出更多符合相应构词法的单词的小组获胜。 第三步：请学生谈谈活动感受，引导学生思考英语词汇的多样性与人类的 创造力之间的关系。 Work in groups. Choose one type and come up with as many words as possible. _abbreviating _changing the part of speech _adding a prefix or suffix _combining two or more words Step5 Homework 总结四种构词法，利用构词法记忆并复习本单元单词。
