6 Finishing Task 2 and 3(10 mins) Individual workIndividual work Step 1: Lead the Ss to scan the letter and try to fill in the blanks first, and then listen and complete the letter.

Then read the sentences together. Pay attention to the weak form, liaison and intonation.S1: Nobody would like to see dirty water…S2: …and not spit anywhere in public.S3: We shouldn’t do anything to destroy …Ss: … 語法是語言組織的規律，沒有語法，語言便只是一些雜亂無章的符號，就會失去英語的工具性。教師在教授語法時，要注意方法和策略。本課要突破不定代詞和不定副詞的用法。先通過聽讀對話，理解各個不定代詞的含義，然后通過語篇填空，讓學生嘗試使用這些不定代詞，然后自己歸納總結他們具體的用法，最后在第四步中檢測學習的程度。在語法習得過程中，教師要注意自己的角色，注意引導學生學會觀察、思考、討論、歸納。
