語法教學(xué)活動片斷

1、語法教學(xué)活動片斷在日常的英語語法教學(xué)中，我們通常使用演繹法、歸納法和指導(dǎo)發(fā)現(xiàn)法。演繹法是由表現(xiàn)語法規(guī)則到具體例證的方法，即由抽象到具體。老師先介紹、講解語法規(guī)則，然后再舉例說明、論證語法規(guī)則，再組織學(xué)生實行練習(xí)和使用。歸納法是教師能夠通過復(fù)習(xí)，讓學(xué)生將平時分散、孤立的知識加以縱橫聯(lián)系，使之系統(tǒng)化、條理化，整理歸納成有機的整體。通過個別語法例證帶出一般帶普通意義的例證，從具體的例證向抽象的歸納轉(zhuǎn)化。此方法優(yōu)勢在于能充分利用學(xué)生已有的知識經(jīng)驗，以舊帶新，讓學(xué)生易于接受并強化使用。下面以現(xiàn)在實行時的教學(xué)為例作說明：Step 1： 教師先表現(xiàn)現(xiàn)在完成時的構(gòu)成：主語+ am/ is/ are +動詞in

2、g + Step2：現(xiàn)在實行時的應(yīng)用(1) 表現(xiàn)例句：They are playing basketball now. We are having an English class now.學(xué)生歸納：當句子中有now時，常表示動作正在實行，這時要用現(xiàn)在實行時。(2) 表現(xiàn)例句： Listen！She is singing an English song. Look! The boy is smiling at us.學(xué)生歸納：以look, listen開頭的句子，提示我們動作正實行，這時要用現(xiàn)在實行時。 (3)表現(xiàn)語法規(guī)則：表示當前一段時間或現(xiàn)階段正在實行的動作，且此時有this week,

3、these days等時間狀語，這時常用現(xiàn)在實行時。如：We are making model planes these days.Where is your father? He is cleaning the car. (4)表現(xiàn)語法規(guī)則：描述圖片中的人物的動作，也為了表達更生動。此時也常用現(xiàn)在實行時。如： Look at the picture. The children are flying kites in the park.Step 3：現(xiàn)在實行時的變化(1)表現(xiàn)現(xiàn)在完成時不同句式的結(jié)構(gòu)：肯定句式：主語+be( am, is, are)+現(xiàn)在分詞+其它.否定句式：主語+be(am,

4、 is, are) +not +現(xiàn)在分詞+其它. 一般疑問句：Be(am, is, are) +主語+現(xiàn)在分詞+其它？ 特殊疑問句：疑問詞+be(am, is, are)+主語+現(xiàn)在分詞+其它？(2) Exercise: They are singing in the classroom.否定句：_一般疑問句：_肯定回答：_否定回答：_對“are singing”提問：_對“in the classroom”提問：_Step 4. 鞏固練習(xí)：用現(xiàn)在進行時完成下列句子。1. We _ (play) games now.2. What are you _(do) now? I _(eat) bre
