一、學(xué)情分析

認(rèn)知基礎(chǔ)：在初中學(xué)習(xí)的基礎(chǔ)上，高一學(xué)生已經(jīng)掌握了一些基本的詞匯學(xué)習(xí)方法并具備一定的詞匯量，而且能簡單用英語地表達個人觀點，但是就高中階段對閱讀的要求，他們的詞匯量非常有限。此外，他們對新詞的理解和運用上存在一定的問題。

二、教學(xué)內(nèi)容分析

詞匯在高中英語乃至整個英語學(xué)習(xí)中都起著舉足輕重的作用，橋梁和紐帶。但是在實際的日常學(xué)習(xí)中，學(xué)生對單詞的記憶和運用都存在很大的問題，導(dǎo)致英語學(xué)習(xí)的低效性。本節(jié)課是這單元的第一課時，學(xué)生要學(xué)習(xí)25個新單詞及7個重點短語的讀音，拼寫，意義和運用并探索有效的詞匯學(xué)習(xí)方法，任務(wù)比較重。

三、教學(xué)目標(biāo)

依據(jù)新課程標(biāo)準(zhǔn)的要求和學(xué)生已有的知識結(jié)構(gòu)與認(rèn)知水平，確定本節(jié)課的教學(xué)目標(biāo)如下：

1、知識與技能：學(xué)習(xí)與野生動物保護有關(guān)的詞匯；能根據(jù)圖片以及上下文語境猜測生詞詞義并能用英語釋義解釋基本單詞；能靈活使用所學(xué)詞匯進行表達；探索有效的詞匯學(xué)習(xí)方法。

2、過程與方法。通過生動的圖片和典型的例句創(chuàng)設(shè)恰當(dāng)?shù)恼Z言情境，來呈現(xiàn)新的詞匯，使之簡單明了，便于理解和掌握。并采用誘導(dǎo)式的教學(xué)方法，引導(dǎo)學(xué)生主動探究，總結(jié)概括，辨析相似的詞匯。合作、討論、競賽、寫作等活動培養(yǎng)學(xué)生自學(xué)、探究、想象、合作的意識與能力。

3、情感態(tài)度與價值觀。培養(yǎng)學(xué)生對保護野生動植物的意識，激發(fā)學(xué)生保護稀有動植物的熱情，最終目的是使學(xué)生理解：保護動植物，就是保護我們?nèi)祟愖约骸?/p>

四、教學(xué)重點與教學(xué)難點

重點：掌握一些基本詞匯的發(fā)音和拼寫，能靈活應(yīng)用重點詞匯，提高對自然保護的意識。

難點：探索有效的詞匯學(xué)習(xí)方式和簡單的構(gòu)詞法 ，提高學(xué)生的自學(xué)能力。
