i.教材分析

本模塊以“ALessoninaLab”為話題，旨在通過模塊教學(xué)，使學(xué)生了解一

些基本的科學(xué)實(shí)驗(yàn)知識(shí)，學(xué)會(huì)怎樣寫實(shí)驗(yàn)報(bào)告，并掌握一些相關(guān)的詞匯與短語(yǔ)，

激發(fā)學(xué)生對(duì)科學(xué)的興趣。此外還要求學(xué)生學(xué)會(huì)讀一些大的整數(shù)、分?jǐn)?shù)及小數(shù)。從

文化的角度來看，鼓勵(lì)學(xué)生了解國(guó)外有關(guān)科學(xué)教學(xué)的情況，以擴(kuò)大學(xué)生的知識(shí)面,

從而激發(fā)他們的學(xué)習(xí)興趣。

1.1INTRODUCTION這部分由三個(gè)內(nèi)容組成。通過聽材料，歸納詞語(yǔ)和回

答問題這三個(gè)形式來完成本部分所涉及到的與科學(xué)、實(shí)驗(yàn)有關(guān)的詞語(yǔ)的練習(xí)，為

以后的各項(xiàng)活動(dòng)做好準(zhǔn)備。

1.2VOCABULARYANDSPEAKING這部分設(shè)計(jì)了一些數(shù)字，包括整數(shù)、
