單元教學目標
本單元是以復習為主，沒出現新的內容。側重點如下：
1. 學習一篇日記，掌握日記寫法，復習一般過去時。
2. 以兩個學生對話，復習一般將來時態。功能項目復習系動詞及情態動詞的用法，復習不定代詞用法。
3. 復習五種簡單句。在閱讀文中復習一般現在時，過去時和將來時。
【重點難點解析】
1. 關于情態動詞的用法
學生用書第110課第一部分列出了到目前為止所學的幾個情態動詞。它們分別是need, needn't; must, mustn't; have to, has to, had to; can, can't; could, couldn't; may。告訴 學生這些情態動詞都有特定的意義，和另一動詞構成謂語，在各種人稱后都用同樣的形式。
(1)need作情態動詞用時，是表示“需要”的意思；主要用于否定句及疑問句中。如：
We needn't start so early. 我們不必這么早出發。
Need I come? 我需要來嗎?
實義動詞need用作及物動詞時，和不定式連用，就可以用于各種結構。如We need to know more about this matter. 關于這件事我們需要了解更多的情況。
Does he need to say something? 他需要說些什么嗎?
He did not need to come. 他并不需要來。
(2)must 表示必須要做的事。如：
You must finish your homework before you watch TV. 你必須做完作業再看電視。
We mustn’t say any longer. 我們不能再說下去了。
在否定回答由must引起的疑問句時，答語用needn't。如：
A: Must we do eye exercises every day? 我們必須每天做眼保健操嗎?
B: Yes, you must. 是的，必須這樣。
No, you needn't. 不，沒有必要。
(3)have to, has to, had to
與must相比，have to表示因客觀環境促使而不得不做的事情。如：
We missed the last bus. We had to walk home. 我們錯過了最后一班公共汽車。我們不得不走回家。
(4)can可表示能力、許可、提供幫助、提出邀請等意思。如：
The apples are too high. He can't reach them. 蘋果長得太高了，他夠不著。
Can I come in? 我能進來嗎?
Can I take a message? 我能留言嗎?
Can you come to my birthday party? 你能來參加我的生日聚會嗎?
could用作can的過去式時，表示能力。如：
I couldn't swim when I was four. 我4歲時還不能游泳。
could還表示委婉地提出請求。如：
Could you wait for a while? 你能等一會兒嗎?
(5)may可表示允許或征詢對方許可和可能性。如：
You may go now. 你現在可以走了。
May I watch TV after supper? 晚飯后我可以看電視嗎?
He may be right. 他可能是對的。
在總結這些情態動詞的用法上，要求學生區分每個情態動詞的不同含義。情態動詞是初中學生學習英語的一個難點，需要學生認真做學生用書和練習冊中提供的練習。
2. 寫日記的格式：一般情況下先寫好日期和天氣情況，請記住日記的基本格式。
日期要頂格寫，可先寫星期，再寫年月日，也可先寫年月日再寫星期。日期的寫法通常用省略形式。如：Monday June 23rd, 1990(June 23rd, 1990 Monday)或Mon. Jun. 23rd, 1990(Ju n. 23rd 1990 Mon. )。
天氣、溫度的寫法：通常是集中排列，寫在日記的左上角，第一個字母大寫。如：Sunny。
日記是記敘當天經過的事，所以謂語動詞多用一般過去時，主語I常常省略。
【命題趨勢分析】
不定代詞用法是常見題之一。請復習本書19單元不定代詞用法，然后做下題。
用不定代詞填空。
1. “I can't hear anything”means“I can hear ”.
2. There is on the floor. please pick it up.
3. Did go to play basketball with you?
4. I phoned you last night, but answered it.
5. I don't think telephoned.
6. Why don't you ask to help you?
7. If you want , Please let me know.
8. Shall we get to drink?
9. Don't worry. There's wrong with your ears.
10. There's in the box. It's empty.
(Answer: 1 nothing 2 something 3 anybody/anyone 4 nobody/no one 5 anybody/any one 6 someone/somebody 7 something 8 nothing)

(2)“記日記”，用keep, keep a diary 記一篇日記。如：

2. I must take her to hospital. 我必須送她去醫院看病。
hospital前不加冠詞，表示看病、就醫。如：

如：The girl looked afraid. 這女孩看上去很害怕。

You look better today. 你今天看上去氣色較好。
4. I can't leave her by herself. 我不能把她一個人留下。

5. at first 起先、起初

注意：時間段+later=after+時間段，都表示過去某段時間之后都要同過去時連用，如：

相當于 He got to Beijing three days later.
但after+時間點，可用于將來時，如：
He will go there after four o'clock. 四點鐘后他將去那兒。
如果要說從現在起某段時間之后，則要用in+時間段。如：

He looked at his watch and found it was ten o'clock. 他看了看表，發現已是十點了。
The students are looking at the map on the wall. 學生們看著墻上的地圖。
see強調看的結果，不一定是有意識的，意為“看見”，如：

I shall not wait any more/longer. 我不再等了。
not…any more也可用作no more, no more即可修飾連系動詞，也可修飾行為動詞，修飾行為動詞時常用于句末，如：

He will go there no more. (=He won't go there any more. )他不再住這兒了。
11. Then I made faces and jumped like a monkey. 接著，我做著怪相，像猴子一樣來回跳著。

The boy made faces and wanted to make the others laugh. 那男孩做著鬼臉，想逗別人發笑。
“Don't make a face. ”said the teacher. “不要做鬼臉”老師說。
(2)like在句中是介詞，作“像”解，后接名詞或代詞(賓格)，如：

I'll tell you everything tomorrow. 明天我將全告訴你。
Tell me your name, please. 請告訴我你的名字。
(2)Whole與all都有“全部的”意思，其區別是：
(1)兩者都可用表示整體的單數名詞之前，但限定詞的位置不同，如：
All the city/The whole city is busy cleaning the streets. 全城的人都忙于打掃街道。
It took him all the year/the whole year to write the book. 寫這本書花了他整整一年。
(2)all表示“所有的”，后接復數名詞，whole表示“所有的”時則須用the whole of, 如：

The whole of the students went to the cinema. 全體學生都去看電影了。
(3)專有名詞、不可數名詞前用all，不用whole如：
all China 全中國(不說：whole China)
all the water 所有的水(不說：the whole water)
13. He can take good care of your babies. 他會照管好你們的孩子的。
(1)take care 不接of，意為“當心”、“小心”，如：
Take care! The ice is thin. 當心，冰很薄。

14. How did Ling Feng make the baby stop crying? 林峰是怎樣使孩子停止了哭泣?
(1)make 在此句意為“使…”，make作“使…”解時，其賓語后的不定式習慣上不帶to。 notice, hear, listen, see, watch, let 用法相同。如：

而stop to do sth. 停下來去做某事。
如：They stopped singing and dancing. 他們停止了唱歌、跳舞。

15. Why did the monkey laugh in the end? 為什么猴子最后大笑?
in the end最后

in the end的反義短語是at first或in the beginning(起先、起初)。如：At first he didn't know how to learn English, but he was good at English in the end when he left middle school.
起初他不知道怎樣學英語，但最后在中學畢業時他的英語已很好了。
如要表示“在…結尾/末端”則要用at the end of…
at the end of the story 在故事的結尾。at the end of the street 在街道的末端。其反義短語則為at the beginning of, 如：at the beginning of this term 在這學期的開頭。
16. He told me not to bring you anything 他告訴我不常帶什么東西給你。
在tell, ask, want, get, like等一些動詞的賓語后，都能接不定式作賓語補足語，其不定式的否定形式是在to前加not，如：
The teacher told him not to make faces in class.
老師告訴他不要在上課時做鬼臉。
(不可說：The teacher told him don't to make faces in class. )
再如：He asked me not to open the door. 他請我不要開門。
His parents want him not to be late for school. 他的父母要他上學別遲到。
17. I'll speak to him. 我要同他談談。
speak 意為“說話”、“演說”，一般用作不及物動詞。作及物動詞時只和少數名詞(如表示語言的詞)連用；若表示“談論某人、某事”其后則接about:

Say it again. 再說一次。

18. Look into the river. 往河里看。

look back 回頭看 look around 向四周張望

典型例題
【課本難題解答】
1. 我不能把她單獨留下。
誤：I can't leave herself.
正：I can't leave her by herself.
析：“把某人單獨留下”，要用“leave one by oneself”結構，而在leave后面不能直接跟oneself。
2. 我不知道我什么時候睡著的。
誤：I didn't know when I was asleep.
正：I didn't know when I went to sleep.
析：be asleep與go to sleep都有“睡覺”的意思，但be asleep表示“睡著”的狀態，go to sleep表示“入睡”的過程，是一種動作。
3. 收音機在那兒，請打開。
誤：The radio is there. Please turn on it.
正：The radio is there. Please turn it on.
析：turn on中的on是副詞。在“動詞+副詞”結構中，若賓語是代詞，必須放在動詞與副詞之間；若賓語是名詞，放在副詞前后都可以。
4. 兩個小時后他回家了。
誤：Two hours after he went home.
正：Two hours later he went home.
正：After two hours he went home.
析：later和after都表示過去某段時間之后，但later常位于時間之后，after常位于時間之前。如：six minutes later或after six minutes(六分鐘后)。
【閱讀分析點撥】
讀短文辨正誤。
An old man thought his wife was a bit deaf and he decided to try her out. He walked ten metres away from the back of his wife and asked, “Can you hear me? ”With no answer from his wife, he went forward(向前方)and stood six metres away from her. “Can you hear me? ”he asked again, but he still got no answer. Then he walked up two metres away from his wife and asked again in a loud voice, “Now, my dear, can you hear me? ”
“Yes, of course. ”she replied. “And this is the third time I've repeated. ‘Yes, of course. ’”
The old man finally knew who was really deaf when he heard this.
( )1. The old man's wife was deaf in both ears.
( )2. The old man wanted to find out if his wife was deaf.
( )3. His wife could hear better than him.
( )4. His wife could hear him from ten metres away.
( )5. He couldn't hear his wife because his wife didn't say anything.
( )6. In fact the old man himself was deaf.
( )7. He asked his wife three times, but his wife only answered him once.
( )8. At last the old man heard what his wife said.
( )9. At last he found out his wife was not deaf.
( )10. His wife answerd him three times, but he only heard once.
答案：1. × 2. √ 3. √ 4. √ 5. × 6. √ 7. × 8. √ 9. √ 10. √
分析：根據妻子的回答“And this is the third time I've repeated. Yes, of course. ” 可以斷定丈夫三次說的話她都聽到了，而且三次都作了回答，這是理解全文的關鍵詞語，不難對1、5、7、題作出否定的判斷，而對4題作出肯定的判斷。第一段的第一句為該段的主題句，恰恰回答了2題。文章結尾一句是本文的主題句。“Who was really deaf”清楚地回答了3、6、8、9、10五個問題。
