教學(xué)反思

教學(xué)中，我們可以采用多種手段幫助學(xué)生多記單詞，多學(xué)習(xí)語(yǔ)言規(guī)則，并盡可能多創(chuàng)造模仿的機(jī)會(huì)，提高學(xué)生的語(yǔ)音和語(yǔ)調(diào)。在英語(yǔ)學(xué)習(xí)中，聽(tīng)、說(shuō)、讀、寫(xiě)、譯五種能力是可以互補(bǔ)的。真正做到聽(tīng)說(shuō)先行，讀寫(xiě)跟上。光聽(tīng)說(shuō)不讀寫(xiě)，很難收到高效。只靠模仿不培養(yǎng)學(xué)習(xí)能力，也難減輕學(xué)習(xí)負(fù)擔(dān)。

2021人教版八年級(jí)英語(yǔ)下冊(cè)教案2

教學(xué)目標(biāo)

3. 通過(guò)閱讀訓(xùn)練來(lái)讓學(xué)生們逐步提高英語(yǔ)閱讀能力。

二、過(guò)程與方法

上網(wǎng)查閱相關(guān)資料，反復(fù)聽(tīng)力，操練對(duì)話(huà)。

三、情感態(tài)度與價(jià)值觀

能用一般過(guò)去時(shí)和過(guò)去進(jìn)行時(shí)敘述過(guò)去的事，特別是重大突發(fā)事件。

教學(xué)重點(diǎn)

What happened to the girl? Let’s listen.

1b, Listen and write short answers to the questions.

1. What event happened at the school yesterday?

2. Who missed the event?

3. Which team won at the event?

Play the recording at least twice and give the students enough time to write down their answers. Then ask some students to report their answers.

1c, Listen again. Number the events [1-6] in the order they happened.

____ Kate saw a dog by the side of the road.

____ Kate got to the bus stop.

____ Kate called the Animal Helpline.

1 Kate left the house.

____ Kate waited for someone to walk by.

____ Kate realized her bag was still at home.

Ask some students to report their answers.

A：When she got to the bus stop，Kate …

B：When she got to the bus stop，Kate realized that her bag was still at home.

A：While she was running back home， …

B：While she was running back home，she saw a dog by the side of the road.

Encourage the students to make up as many dialogues as possible.

Step 6 Presentation

2a, Look at the pictures and the title in the passage. What do you think the passage is about?

Remind the students to talk about it in pairs. Then ask some students to report their answers.

Step 7 Reading

2b, Read the passage and answer the questions:

1. What are the two events in the passage?

2. When did they happen?

Ask some students to report their answers.

2c Read the passage again. Are the following statements true (T) or false (F)，or is the information not given (NG)?

___ 1. Everyone in America remembers who killed Dr. King.

___ 2. Robert Allen was eating lunch when Dr. King was killed.

___ 3. Robert’s parents were shocked to hear the news.

___ 4. Kate Smith was watching a movie when a plane hit the World Trade Center.

___ 5. Kate didn’t think her friend was telling the truth about the event.

Ask some students to report their answers.

2d Underline sentences from the passage with similar meanings to the ones below.

1. Not everyone will remember who killed him，but they can remember what they were doing when they heard that he got killed.

2. No one said anything for the rest of dinner.

3. September 11，2001—— the date alone means something to most people in the US.

4. I had trouble thinking clearly after that because I was very afraid.

Ask the students to read the passage carefully and try to find out the answers.

Step 8 Language points

1.My parents did not talk after that，and we finished the rest of our dinner in silence.

in silence 沉默，無(wú)聲

e.g. Many patients were waiting in silence. 許多病人在靜靜地等候著。

2. I didn’t believe him at first.

at first “起初，首先”，作為介詞短語(yǔ)，只起副詞作用(在句中用作狀語(yǔ))。 at first主要用于強(qiáng)調(diào)前后對(duì)照，暗示接下去的動(dòng)作與前面的動(dòng)作不同甚至相反，因此常有 but， afterwards，soon，at last等相呼應(yīng)。

e.g. At first I didn’t want to go，but soon I changed my mind.

我開(kāi)始不想去，但我很快就改變了主意。

Step 9 Pair work

2e, How much do you remember about the events in the passage? Test your partner.

A：When did Dr. Martin Luther King die?

B：He died on …

教學(xué)反思

2b部分課本上已經(jīng)設(shè)計(jì)了很多閱讀理解活動(dòng)，但如果能再加一個(gè)寫(xiě)的活動(dòng)更好。對(duì)于閱讀理解中涉及到的兩個(gè)重大歷史事件，讓學(xué)生在充分學(xué)習(xí)文章的基礎(chǔ)上復(fù)述一下并寫(xiě)出來(lái)，不僅鍛煉了學(xué)生的概括能力，又培養(yǎng)了學(xué)生的寫(xiě)作能力，同時(shí)復(fù)習(xí)鞏固了本課的重點(diǎn)語(yǔ)法——過(guò)去進(jìn)行時(shí)。

Step 2 A Game

Show a list of chores on the blackboard：

do the dishes clean your room

take out the trash sweep the floor

fold your clothes make your bed

Give them a set of blank cards.

T：Let’s play a game. You will work in groups of four. First each group writes the chores on the cards. Put them face down. The first student turns over a card，and asks the student next to him/her to do this chore. That student says “no” and gives a reason. Each student should give a reason that has not been given before. The one who can’t give a proper reason will be out of the game. Those who can keep coming up with reasons will be the winner.

Step 3 Role play

Ask some pairs to role play the dialogue in 2d.

Step 4 Presentation

Say：As we all know，Mother does almost all the housework in the house. She is always tired. Should we help Mother? What we can do to help her? Ask some students to report their answers.

Step 5 Reading

Say：Now let’s read an article about Nancy and her mother. Please read quickly and answer the questions：1. Why was Nancy’s mom angry with her? 2. Did they solve the problem? How?

Then ask some students to report their answers.

Now let’s read the sentences in 3b，try to understand and translate them. Then read the passage again carefully and try to underline the sentences from the reading that mean the same thing. After several minutes， ask some students to report their answers and translate the sentences into Chinese.

Step 6 Language points

1. You watch TV all the time and ...

all the time(在該段時(shí)間內(nèi))一直;向來(lái)，一向;時(shí)時(shí)刻刻;每時(shí)每刻

e.g. I do this all the time. 我一直是這么做的。

This happens all the time. 這種情況是時(shí)時(shí)發(fā)生的。

2. I’m just as tired as you are!

as ... as 意為 “和…一樣”，表示同級(jí)的比較。使用時(shí)要注意第一個(gè)as為副詞，第二個(gè)as為連詞。其基本結(jié)構(gòu)為：as + adj./ adv. + as。

e.g. This film is as interesting as that one. 這部電影和那部電影一樣有趣。

Your pen writes as smoothly as mine. 你的鋼筆書(shū)寫(xiě)起來(lái)和我的一樣流暢。

注意：as … as 的否定形式為“not as/so + adj./adv. + as”。

e.g. He didn’t act as well as you. 他表現(xiàn)得不如你好。

3. For one week，she did not do any housework， and neither did I.

1) neither 用作副詞，作“也不”解釋?zhuān)旁诰涫?，表示前面否定的?nèi)容也適用于另一個(gè)人或物，句子須采用部分倒裝。此時(shí)也可用nor替換 neither 使用。

e.g. --- I don’t like this dress. 我不喜歡這件連衣裙。

--- Neither / Nor do I. 我也不喜歡。

注意：neither 之后的主語(yǔ)要置于助動(dòng)詞或系動(dòng)詞之后。

2) neither 用作代詞，表示“兩者都不，雙方均不”。

He answered neither of the letters. 他兩封信都沒(méi)回。

e.g.--- Which one would you like? 你喜歡哪一個(gè)?

--- Neither. 兩個(gè)都不喜歡。

Step 7 Practice

3c, Show the sentences on the screen： 1. Could you take the dog for a walk? 2. I walked home from school. Then ask some students to read and translate them. Then help them to say that the word “walk” in the first sentence is a noun and the word “walked” in the second sentence is a verb. Then ask the students to look at the sentences in 3c and decide whether the underlined words in the sentences are verbs or nouns. Then write another sentence using the underlined word in the other form. Finally ask some students to report their answers.

Step 8 Grammar focus

Ask the students to translate the sentences in the box and try to remember them. Then practice them in pairs. Finally ask the students to make up more similar dialogues.

Step 9 Practice

4a First ask the students to translate the sentences from 1 to 5，then decide whether they are requests or permissions. Then match each one with the correct response. Finally ask the students to practice the dialogues in pairs.

4b First ask the students to fill in the blanks in the conversation by themselves and then ask them to check the answers in pairs. Finally ask them to practice the dialogue in pairs.

Step 10 Group work

Say：Boys and girls，we’ll go for a camping trip tomorrow. And today we should prepare what we need. Please work in groups and make a list of things your group needs to do for a camping trip. Then discuss who will do them and complete the chart in 4c. You can use the dialogue to help you：A：Could you please bring a tent， Liu Chang? B：Sure. And could you please…? C：Sorry，I can’t. I have to… After several minutes，ask some groups to practice the dialogue.

教學(xué)反思

一節(jié)課下來(lái)，大部分學(xué)生都能積極投入到課堂教學(xué)中來(lái)，并積極舉手發(fā)言。課堂氣氛比較活躍，調(diào)動(dòng)了大部分學(xué)生聽(tīng)課的積極性，因此合作教學(xué)對(duì)提高學(xué)生實(shí)際的語(yǔ)言交流能力以及與他人的合作能力有很大的促進(jìn)作用。但很明顯，語(yǔ)言表達(dá)能力強(qiáng)的學(xué)生參與的機(jī)會(huì)相對(duì)要多，代表小組匯報(bào)的機(jī)會(huì)也多，而另有一些學(xué)生卻習(xí)慣于當(dāng)聽(tīng)眾，被動(dòng)地接受別人的觀點(diǎn)，很少發(fā)表自己的個(gè)人意見(jiàn)，也就是說(shuō)在小組合作學(xué)習(xí)中學(xué)生的參與度不均衡，而這部分學(xué)生主要是學(xué)習(xí)困難生。
