英語Tomorrow is world教案設計
Unit 3 Tomorrow's world
課堂設計指導思想：
本節課是以讀、寫為主的詞匯教學課。內容包括用名詞或動詞加上后綴構成抽象名詞，以及與電腦相關的詞匯等。學習一定的構詞法知識，可以有效地拓展學生的詞匯量。通過構詞法教授詞匯，不僅可以使學生利用較少的時間掌握較多的詞匯，而且還可以使學生通過對詞綴的了解來猜測詞義，從而擴大詞匯量。本課主要通過引導學生自行歸納抽象名詞的構成規律的方法進行教學，不僅有助于增加學生的詞匯量，而且可以使學生初步形成自己的詞匯認知策略，學會根據詞根及后綴來猜測詞義。
Teaching aims:
1. Learn how to form abstract nouns from verbs and adjectives by adding suffixes.
2. Learn some words related to computers.
3. Expand related vocabulary and apply them practically.
Teaching procedures:
Step 1 Revision
Help students revise the common suffix used to form adjectives learnt in Unit 1 using the following chart and ask students to give more examples.
Suffix Meaning Examples(adjectives)
-ical having the quality of medical, electrical, grammatical, practical
-able having the ability of believable, acceptable, reasonable, enjoyable
-ous like, full of adventurous, dangerous, prosperous, conscious
-ful characterized by joyful, helpful, useful, mouthful, handful
-less without useless, careless, helpless, hopeless, cloudless
【設計說明】復習以前所學的構詞法知識，激活學生對后綴的相關記憶，以舊帶新，有助于提高學習效率。
Step 2 Lead-in
1. Ask students to compare the following two groups of words.
Group 1: house, milk, driver, dog, paper
Group 2: revision, preparation, decision, difference, arrangement
Ask students to consider the following questions:
(1) Which part of speech is each of the following words?
(2) What are the similarities and the differences between the two groups?
Answers
(1) They are all nouns.
(2) The words in Group 1 refer to physical things and those in Group 2 refer to ideas, actions and qualities.
2. Tell students that the nouns in Group 2 are called abstract nouns. Ask students to read the definition of abstract nouns on page 46.
3. Ask students to think of more abstract nouns. And show them the following words as examples:
revision, direction, decision, preparation, satisfaction, argument, judgement, disappointment, excitement, civilization, dependence, difference, assistance, pleasure, loyalty, cruelty, action, failure, carelessness, happiness
【設計說明】通過分析、對比，引導學生自己發現抽象名詞的特點，即不可為人的五官感知。隨后在明確抽象名詞的.定義后，用實例加深學生的印象。
Step 3 Ways to form abstract nouns from verbs and adjectives
1. Ask students to categorize the words on the black board according to the suffixes. Then ask students to see what words they are and which part of speech they are if the suffixes are removed using the following form.

2. Ask students to read the instructions on page 46. Ask them to compare the words on the screen with the words in the tables.
3. Tell students that most abstract nouns are uncountable, only a few of them are countable. Ask them to read the following examples:
