一、教學目標
1.詞彙
二、教學重點
1.詞組: wear out, either … or…, so… that… , be busy doing sth, think about
2.語法: 過去完成時
三、教學難點
過去完成時
四、重點難點講解
shoes are worn out. 我的鞋穿破了。
be worn out “穿破了，穿舊了 ” 它是wear out 的被動形式，但是實際上不強調被動，而強掉狀態或情況，因此worn out相當於一個形容詞短語。如：
His clothes were worn out. 他的衣服穿破了。
He has worn out three pairs of shoes.他已經穿破了三雙鞋了。
be worn out“筋疲力盡”，相當於be tires out.多指人的情況。如：
He came back from school and he was worn out. 放學回家他筋疲力盡了。
I was so worn out after that planting. 那次植樹之後我筋疲力盡。
2．I’m looking for a pair of black shoes. 我在找一雙黑顏色的鞋子。
a pair of shoes 一雙鞋 a pair of gloves 一副手套
a pair of glasses 一副眼鏡 a pair of trousers 一條褲子
a pair of stocking 一雙長統襪
另a pair of 也可指夫婦，如：
They are a happy pair. 他們是幸福的一對。
in pairs “兩個兩個的” “兩個之間”如：
Please check the answers in pairs. 請兩個人之間覈對一下答案。
3．What size do you want? 你穿多大號的鞋？
就衣服，鞋類的尺寸大小的提問常用what size 如：
What size shoes do you wear ? 你穿多大號的鞋？
What size is your bedroom? 你臥室的房間有多大？
4．a bit 和a little
二者在肯定句中修飾形容詞或副詞時可通用，表示“一點兒”， “有些”
It’s a bit/a little cold today. 今天有點兒冷。
I’m a little/a bit tired today. 我今天有點累。
但是not a bit “一點也不”；not a little“非常”相當於very 如：
I’m not a bit tired. 我一點也不疲倦。
I’m not a little tired. 我非常疲倦。
5．I don’t think I’ll take it. 我想我不會買。
think長與介詞或副詞連用， 如：
think about 考慮
think of 想到， 想
think out 想出
Please think about how to tell her the bad news. 請考慮一下如何把這不幸的消息告訴 他。
What do you think of the music? 你認爲這段音樂怎麼樣？
5．I don’t think I’ll take it. 我想我不會買。
在英語裏， 當think後面的賓語從句含有否定概念，通常形式上否定think，而實際意義上否定賓語從句。如：
I don’t think you’re right. 我認爲你不對。
I don’t think she will come. 我認爲她不會來。
6. That’s much too expensive! 這太貴了！
much在此起強調作用。
too, much too 和too much
too用在形容詞或副此前，如：
He is too careless in doing anything. 他做任何事都太粗心。
The book is too difficult for students of Grade One. 這本書對於一年級學生太難。
much too 的中心詞是too, much修飾too,用以加強語氣，如：
You are much too kind to me. 你對我實在太好了。
The shirt is much too expensive. 這件襯衫實在太貴了。
too much的中心詞是much, too修飾much,以加強語氣。too much修飾不可數名詞，意爲 “more than enough”與too many相對，後者修飾可署名詞。如：
I drank too much beer last night. 昨晚我啤酒喝的太多了。
There is too much smoke in the room. 房間裏的煙太多。
7．next week 和the next week
next week與一般將來時連用；the next week(the following week)與一般過去是或一般過去將來時連用。如：
We’ are going to plant trees next week. 瞎周我們將要去種樹。
They had a maths test the next week. 第二週，他們考了數學。
8．because,since, as 和for
because是從屬連詞，它引導的原因狀語從句標誌介的與哦明確的原因活力有，語氣較強，如不說，則不爲人們所知。它多用於主句之後。如：
She didn’t come to school yesterday because she had a high fever.
她昨天因發燒沒來上學。
as和since也是從屬連詞， 表示已爲們所知或顯而易見的原因或理由。 as連句since連句多用於主句前。如：
As(Since) you are not feeling well, better stay home.
既然你不太舒服，還是留在家裏吧。
Since everybody is here, let’s begin our meeting.
既然大家都到了，我們就開會吧。
for是並列連詞，引導一個並列句，語氣最弱，表示一種補充說明，即使不說人們也能知道其原因。它引導的分句只能位於後面，不能位於句首。如：
I had to stop for a rest.,for I was too tired. 我只好停下來休息一下，因爲我太累了。
9．either的用法
形容詞或代詞“二者之一，二者任一”
1)用作代詞時，可單獨使用，也可以和表示範圍的of短語連用，of後的名詞一般爲附屬，並且是特指。如：
Has either of your parents visited you? 你父親或母親來看過你嗎？
2)用作形容詞，修飾單數可數名詞，“兩個中任一”，其謂語應是單數形式。如；
Come on Tuesday or Wednesday, Either day is Ok.
星期二活性其三來吧，這兩天哪一天都行。
Either way will do. 這兩種方法哪一種都行。
3)用作副詞時，“也（不）”用於否定句，與too相對，後者用於肯定句。如：
If you don’t go, I won’t ,either. 如果你不去，我也不去。
4)either…or…可表示兩種可能，意爲“不是……就是……”; “或者……,或者……”,連接兩個並列成分或並列分句。如：
You may come either before class or after class. 你可以課前或課後來找我。
either…or…連接兩個主語時，其謂語應與後面的主語在數上保持一致。neither…nor…,和 not only…but also…連接兩個主語時也是這個情況。如：
Either you or I am to go. 不是你去，就是我去。
Neither you nor he is right. 你和他都錯了。
Not only you but also your teacher was wrong. 不但你們，而且你們的老師也都錯了。
10．They were so pleased to see each other that they forgot everything else.
他們相互見面時如此高興以至於把別的事都忘了。
so是副詞，在其後跟形容詞或副詞+that引出結果狀語從句，表示“如此……以至……”如：
He spoke so fast that I could not understand him. 他說的這樣快，我聽不懂他的話。
如果so前面是系動詞be, become, feel等，那麼so後面一般跟形容詞，如：
He became so angry that he couldn’t speak. 他氣的話都說不出來了。
She was so happy that she danced. 他高興的跳起舞來。
如果so的前面是實義動詞，那麼so後面跟副詞。如：
He ran so quickly that he won the race. 他跑得非常快，以致於贏得這場比賽。
