八年級英語第二單元How do you come to school?
章節(jié) 第二單元
關(guān)鍵詞
內(nèi)容
一、教法建議
【拋磚引玉】
本單元主要內(nèi)容：（一）復(fù)習(xí)一般現(xiàn)在時(shí)；（二）專有名詞的使用；（三）生詞及習(xí)語。本單元知識點(diǎn)多而雜，但都很重要，而交際部分與日常生活比較密切，因此，應(yīng)多創(chuàng)設(shè)語言環(huán)境。在課堂上，應(yīng)以對話、問話為主。每講一個(gè)知識點(diǎn)時(shí)，應(yīng)配合一個(gè)例子，測試學(xué)生的反應(yīng)力、接受力及創(chuàng)造力。使學(xué)生在語言環(huán)境中，領(lǐng)悟到語言的功用及魅力。
【指點(diǎn)迷津】
根據(jù)本單元知識點(diǎn)多實(shí)用性強(qiáng)的特點(diǎn)，應(yīng)多用舉例法和聯(lián)想法激發(fā)學(xué)生興趣。
（一）本單元難點(diǎn)：1.復(fù)習(xí)一般現(xiàn)在時(shí)。2.專有名詞的使用。3.新詞匯及習(xí)語的記憶4.本單元知識點(diǎn)：
(1)How
much
…can you…？
many
例如：①How many birds can you see?
②How much fish can you catch?
（2）go (come)+by car /train /bike /bus
go (come)+in a car/in his car.
例如：①They go to The Great Wall by train.
②We come here in my car.
(3)go (come)+on foot (一種動(dòng)作)
be+on foot (一種狀態(tài))
例如：We go to the zoo on foot .
（4）Walk to+名詞
Walk+副詞（不用to）
例如： ①Let\'s walk to the clothes factory.
②It isn\'t too far .Let\'s walk there.
(5)句型對比：
①I usually come to school by bus.
But today
I on foot （×）
I\'m on foot （√）
②How does your father
go to work?（√）
go to his factory?（√）
go to there?（×）
③How many students usually come to school
by their bikes?（×）
on their foot ?（×）
by bus ?（√）
(6)關(guān)于have的含義:
①have supper吃晚飯;②have lessons上課。
例如：
We have supper at 7:30 every day.
How many lessons do you have today?
（二）解決難點(diǎn)的關(guān)鍵:結(jié)合本課知識點(diǎn)多而雜的特點(diǎn)，要通過各種簡單易懂的例子，使學(xué)生在教師的指導(dǎo)下模仿例子，然后讓學(xué)生造出新的例句。
二、學(xué)海導(dǎo)航
【學(xué)法指要】
為了幫助學(xué)生鞏固本單元所學(xué)知識,精選以下幾道不同類型的題目,僅供參考。
1.How______do you want ? Ten kilos.
A.much rice B.many rice C.much rices D.heavy rice
【提示】四個(gè)選項(xiàng)很接近，關(guān)鍵要明確rice是不可數(shù)名詞,這樣答案就不難選了。
【答案】A
2、_______moon goes around the earth ,and the earth goes around_______sun .
A、The…不填 B.不填…the C.不填…不填 D.The…the
【提示】定冠詞the用于表示世界上獨(dú)一無二或被視為整體的東西的名詞前。例如： the sun,
the moon， the earth， the sea，the land，the sky， the weather。
【答案】D
3、Open the window!_______is nice and clean.
A、Today air B.Air of today C.Air today D.The air today
【提示】 today作后置定語修飾air , air前要加定冠詞the.
【擴(kuò)展】The air today is nice and clean.意思是:今天的空氣非常／很清新。英語nice and和good and同樣是一個(gè)習(xí)慣用語，用在形容詞之前加強(qiáng)語氣,其含義是very (很、非常),實(shí)際上就是一個(gè)偏正結(jié)構(gòu),nice and對后面的形容詞起了修飾作用。
例如： I was good and hungry.我當(dāng)時(shí)很餓。
【答案】D
4.We often_______(clean )our classroom after school.
【提示】一般現(xiàn)在時(shí)表示經(jīng)常性、反復(fù)性和習(xí)慣性的現(xiàn)時(shí)行為。當(dāng)句子主語為除第三人稱單數(shù)外的其他人稱時(shí)（一、二人稱單數(shù)及復(fù)數(shù)各人稱），一般現(xiàn)在時(shí)的構(gòu)成為動(dòng)詞原形。由于一般現(xiàn)在時(shí)所表現(xiàn)的是現(xiàn)時(shí)行為的三性（經(jīng)常性、反復(fù)性和習(xí)慣性），所以常用的時(shí)間狀語有：often，sometimes， every，usually，always， normally等。
【答案】clean
5.Who_______(watch)TV every day? Do you know?
【提示】首先看時(shí)間狀語，判定是一般現(xiàn)在時(shí)。然后，判定用watch還是watches,在不知道是誰的情況下，一律用單數(shù)。
【答案】watches
6.What time do the students have lunch?(用Tom改句子)
【提示】完成本題關(guān)鍵在于要明確一般現(xiàn)在時(shí)的構(gòu)成：
①主語+謂語+賓語+狀語；
②當(dāng)主語是一、二人稱或復(fù)數(shù)人稱時(shí)，謂語動(dòng)詞不變；
③當(dāng)主語是單數(shù)第三人稱時(shí)，謂語動(dòng)詞要變化（+s或es），如變此句為一般疑問句用does，然后謂語動(dòng)詞恢復(fù)原形。
【答案】What time does Tom have lunch?
7.“_______do they get there?”“By air.”
A、What B. Where C. How D. Which
【提示】By air意思是by plane，譯作乘飛機(jī)。對by air進(jìn)行提問,在四個(gè)選項(xiàng)中只有C是對的。
【答案】C

Mr Brow had to do as his wife said. The next afternoon Bill came back and showed his exercise-book to his father. The man had a look at it and shouted to his wife,“ come here quickly ,dear ! I got an A in maths!”
【思路點(diǎn)撥】
1.第一句就告訴讀者，Mr Brown was born in a poor family ,接下來講，He couldn\'t go to school .就是說Mr Brown未能上學(xué)是因?yàn)樗揖池毢?
2、在文章中指出：The boy likes nothing except playing,這就是他無法完成作業(yè)的最主要原因。
3、Their son, Bill ,began to go to school last year.從這句話可以看出Bill還不到十歲，像這么大的孩子，哭泣大都是為了一些小事。

1.Which of the following is true?
A. Mr Brown was going to be a porter when he was young.

【分析】
首先明確1英磅應(yīng)是an English pound, 1美元應(yīng)an American dollar,然后根據(jù)自己的課外知識，來判定哪個(gè)選項(xiàng)是對的。
【答案】A
三、智能顯示
【心中有數(shù)】
本單元重點(diǎn)：一般現(xiàn)在時(shí)和專有名詞的使用。在各級各類考試中，一般現(xiàn)在時(shí)是必考時(shí)態(tài)，而專有名詞偶而出現(xiàn)。
