1、Un it 3 Tomorrow's world課堂設(shè)計指導(dǎo)思想：本節(jié)課是以讀、寫為主的詞匯教學(xué)課。內(nèi)容包括用名詞或動詞加上后綴構(gòu)成抽象名詞， 以及與電腦相關(guān)的詞匯等。學(xué)習(xí)一定的構(gòu)詞法知識，可以有效地拓展學(xué)生的詞匯量。通過構(gòu)詞法教授詞匯，不僅可以使學(xué)生利用較少的時間掌握較多的詞匯，而且還可以使學(xué)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(dǎo)學(xué)生自行歸納抽象名詞的構(gòu)成規(guī)律的方法進行教學(xué)，不僅有助于增加學(xué)生的詞匯量，而且可以使學(xué)生初步形成自己的詞匯認知策略，學(xué)會根據(jù)詞根及后綴來猜測詞義。Teach ing aims:1.
