2.教學(xué)難點(diǎn)：用所學(xué)知識會話，寫出簡短的文章。

●教學(xué)設(shè)計(jì)：

Step1：Review

1.Listen to an English song Old MacDonald Had A Farm to warm up and lead to the new lesson.

2.After listening,the teacher says,“Do you know the name of the song?Yes,it’s Old MacDonald Had A Farm.It’s about animalsand farms.Can we find farms in the city or in the countryside?Which do you prefer,the countrysideor the city?”

（設(shè)計(jì)說明：通過適時(shí)合理的提問，引發(fā)學(xué)生的思考，激發(fā)學(xué)生的表達(dá)欲望，并通過合理想象來完成表述。）

Step2：Presentation

1.Lead to 1a.The teacher shows two pictures,one with beautiful scenery in the countryside and the other with polluted scenery in the city,and then speaks to students,“Today we’ll learn Topic1,Unit4.Look at these two pictures.I thinkmostof us prefer the countryside.Ithas fresher air,bluer sky,greener treesand clearer rivers.People can enjoy the beautiesofnature there.”

Write down the underlinedwordsand letstudents learn the new ones.Master“countryside”，“sky”，“clear”and“nature”. Uderstand the new word“beauty”.Then mark“fresher”，“bluer”，“greener”and“clearer”with colored chalk and let students observe them to getan initial perception of comparative degreeofadjectives.

（設(shè)計(jì)說明：通過兩張圖片的對比，引入形容詞比較級，在情境中提高學(xué)生的語言交際能力，凸顯語言交際功能。）

2.Listen to1a,and answer the followingquestions.

（1）DoesWangWei like the life in the countryside?

（2）How doeshe think about the life in the countryside?

（設(shè)計(jì)說明：通過提出具體問題，鞏固上一部分的學(xué)習(xí)內(nèi)容，并了解學(xué)生掌握知識的程度，同時(shí)培養(yǎng)學(xué)生自己組織語言的應(yīng)變能力。）

Step3：Consolidation

2.Letstudentsread 1aand do1baccording to1a.Finish1b.

Step4：Practice

There aremany animals on the farm.Can you say their names in English?”The teacher leads students to answer and writes down the new words on the blackboard.Master“cow”，“horse”，“hen”，“sheep”，“goose”and“thin”.

2.Letstudents listen to 2a.Read after the tape and imitate the pronunciation and intonation.

3.Let students read 2a and pick out the sentences which have comparative and superlative degreesofadjectives.Forexample:

He is lazier thanme.

I’m smaller than you.

but I’m faster.

I’mmuch faster than you.

I’m a littlebigger than you.

Encourage students to sum up the changing rules of comparative and superlative degrees of adjectives and then the teachergives additionalexplanations.Ask students tomaster the expressions of comparative and superlative degrees of adjiectives.

（設(shè)計(jì)說明：通過讓學(xué)生先總結(jié)形容詞的比較級和最高級的變化規(guī)則，然后教師加以補(bǔ)充，一步步由淺入深，鍛煉學(xué)生的思維和信息處理能力，發(fā)揮他們創(chuàng)造性使用英語的能力，養(yǎng)成良好的交流合作、互通的學(xué)習(xí)習(xí)慣。）
