球,還是其他星球有類似的或更智能的生命存在?此處的設(shè)計(jì)旨在引起同學(xué)們的興趣從而展開熱烈討論,激發(fā)了他們對(duì)天文學(xué)的進(jìn)一步了解和探究的興趣。Step 5.Homework:1. Find out language points and noun clauses in the reading passage. Discuss and analyze them.2. Rewrite the passage and use as many language points and new words as possible.3. Questionnaire.學(xué)生課后完成找名詞性從句(主語(yǔ))為本單元的語(yǔ)法項(xiàng)目的學(xué)習(xí)做準(zhǔn)備,同時(shí)課后鞏固上課所學(xué)的內(nèi)容。七、教學(xué)評(píng)價(jià)設(shè)計(jì)通過以下的一系列問題的設(shè)置,讓學(xué)生對(duì)本課時(shí)閱讀內(nèi)容的學(xué)習(xí)進(jìn)行評(píng)價(jià):Questionnaire:1.
