【重點難點解析】
1. 情態動詞could的用法
(1)用作一種委婉的語氣向對方提出建議或請求，在這種情況下，它與can沒有時間上的區別，可以換用，但could比can更委婉、更有禮貌。例如：
Could you ask him to call me, please?
請你讓他給我打電話好嗎?
(2)表示“過去能夠/有能力……”，could/couldn't是can/can't的過去式，在這種情況下，can與could不能互換，can表示現在或目前的狀況，而could表示過去的狀況，兩個詞有時間上的差別。例如：
Could you swim two years ago? 兩年前你會游泳嗎?
No, I couldn't. 不，我不會。
2. 反身代詞
(1)形式：
單數
myself yourself himself herself itself
復數
ourselves yourselves themselves
(2)一般情況下，當句子的主語和賓語是同一個人時，我們常用反身代詞作賓語。有些詞與反身代詞構成固定搭配：
①(all) by oneself 獨自，靠某人自己. 如：
She can do it all by herself. 她可以完全靠自己做這件事。
②hurt oneself 傷著自己，受傷. 例如：
I hope she didn't hurt herself. 我希望她沒受傷。
③teach oneself. . . =learn sth. by oneself 自學. 例如：
He teaches herself English. 她自學英語。
=She learns English by herself。
④buy oneself sth. 給自己買某物。例如：
I can buy myself lots of good things. 我可以給自己買許多好東西。
⑤enjoy oneself 過得愉快 (=have a good time)。例如：
I always enjoy myself. 我總是過得愉快。
=I always have a good time.
⑥look after oneself 自己照料自己。例如：
He could not look after himself. 他不能自理。
⑦wash oneself. 自己洗漱。例如：
He could not wash himself. 他不能自己洗漱。
⑧help oneself to. . . 請隨便(取、吃什么東西)。例如：
Help yourselves to the cakes. 請隨便吃些蛋糕。
【命題趨勢分析】
用反身代詞填空。
1. Be careful not to hurt .
It's a new knife.
2. I don't need any help.
I can do it all by .
3. -Do you enjoy ?
-Yes, we enjoy very much.
4. Look at . What's wrong with your face?
5. She thinks more of others than of .
6. -Who taught her?
-Nobody! She taught .
7. He could not wash or get dressed.
8. Help to some cakes.
答案與解析：
1. yourself。“傷著自己”是hurt oneself，因為是祈使句，所以填yourself。
2. myself。all by oneself意為“完全靠自己”，意即不需別人幫助，因為主語是第一人稱I，所以應填myself。
3. yourselves, ourselves。“玩得痛快”用enjoy oneself，前句主語是you，答語的主語是we，由此可知you是復數，所以兩空應填yourselves, ourselves。
4. 從該句句意可知，所填反身代詞應為第二人稱，作look at的賓語。應填yourself。
5. herself。該句意為“她為別人想的比自己多”，主語是she，所以應填herself。
6. herself。“自學”譯為teach oneself，主語是she，所以賓語要用herself。
7. himself。主語是he，動詞wash的賓語應為himself。
8. yourself help oneself(to) 意為“隨便吃……”，又因為是祈使句，所以應用第二人稱，該空應填yourself。

典型例題
【課本難題解答】
1. 選擇填空。
Please when the train leaves.
A. find B. look for C. find out D. found out
解析：答案C. find與find out都有“發現”的意思。find表示偶然發現某物，find out指經過一番努力之后才發現某物，查出某事。而look for意為“尋找”只表示動作，不表示結果。所以正確答案為C。
2. 用所給動詞的適當形式填空。
The Greens (have) breakfast now.
解析：從句中時間狀語now判斷，該句的謂語動詞是正在發生，因此是現在進行時態，the Greens是姓氏復數前加the表示“……一家”是復數形式，所以正確答案是are having.
3. 用所給單詞的適當形式填空。
They enjoyed (they) at the party.
解析：當動詞所表達的動作反射到動作者本身時，應該用反身代詞。enjoy oneself是固定搭配，所以應填themselves.
4. 改錯：
Can you swim when you were 5 years old?
A B C D
解析：本句意為“你五歲時會游泳嗎? ”指的是以前的事，用一般過去時，因此can應為could。A錯。
【閱讀分析點撥】
I arrived in the United States on February 6, 1986, but I still remember my first day here very clearly. My friend was waiting for me when my plane landed at Demedy Airport at three o'clock in the afternoon. The weather was very cold and it was snowing, but I was too excited to mind. From the airport, my friend and I took a taxi to my hotel. My friend helped me unpack at the hotel and then left me because he had to go back to work. He promised(答應)to return the next day.
Shortly after my friend had left. I went to a restaurant next the hotel to get something to eat. Because I couldn't speak a word of English, I couldn't tell the waiter what I wanted.

關于“Unit 21 She taught herself”的常見問題】
常見問題1: Unit 21
問題：
1. We should(應該) find out the answer by .

C. Yes, please D. No, thank you
解答:
1. C. “by+反身代詞”意為“獨自”、“單獨”，相當于alone。在by前加all，起加強語氣作用。
2. D. “the+復數姓氏”意為“某某一家人”或“某夫婦”。
3. C. called Lucy在這里意為“被稱作露茜的”。該短語叫過去分詞短語，作后置定語，修飾前面的名詞。
4. D. “help+反身代詞+介詞to”意為“隨便吃些……”，是招待客人的禮貌用語。本題因勸請的對象不是一人(注意children)，故不能用C。
5. D. 對方勸請你吃東西時，按英美人的習慣，道聲“謝謝”后便可毫不客氣地吃；如果真的不想吃或吃飽了，應該禮貌地加以拒絕，這時常說“No, thank you(thanks). ”等。
