一、教学目标
1.词汇
二、教学重点
1.词组: wear out, either … or…, so… that… , be busy doing sth, think about
2.语法: 过去完成时
三、教学难点
过去完成时
四、重点难点讲解
1.My shoes are worn out. 我的鞋穿破了。
be worn out “穿破了，穿旧了 ” 它是wear out 的被动形式，但是实际上不强调被动，而强掉状态或情况，因此worn out相当于一个形容词短语。如：
His clothes were worn out. 他的衣服穿破了。
He has worn out three pairs of shoes.他已经穿破了三双鞋了。
be worn out“筋疲力尽”，相当于be tires out.多指人的情况。如：
He came back from school and he was worn out. 放学回家他筋疲力尽了。
I was so worn out after that planting. 那次植树之后我筋疲力尽。
2．I’m looking for a pair of black shoes. 我在找一双黑颜色的鞋子。
a pair of shoes 一双鞋 a pair of gloves 一副手套
a pair of glasses 一副眼镜 a pair of trousers 一条裤子
a pair of stocking 一双长统袜
另a pair of 也可指夫妇，如：
They are a happy pair. 他们是幸福的一对。
in pairs “两个两个的” “两个之间”如：
Please check the answers in pairs. 请两个人之间核对一下答案。
3．What size do you want? 你穿多大号的鞋？
就衣服，鞋类的尺寸大小的提问常用what size 如：
What size shoes do you wear ? 你穿多大号的鞋？
What size is your bedroom? 你卧室的房间有多大？
4．a bit 和a little
二者在肯定句中修饰形容词或副词时可通用，表示“一点儿”， “有些”
It’s a bit/a little cold today. 今天有点儿冷。
I’m a little/a bit tired today. 我今天有点累。
但是not a bit “一点也不”；not a little“非常”相当于very 如：
I’m not a bit tired. 我一点也不疲倦。
I’m not a little tired. 我非常疲倦。
5．I don’t think I’ll take it. 我想我不会买。
think长与介词或副词连用， 如：
think about 考虑
think of 想到， 想
think out 想出
Please think about how to tell her the bad news. 请考虑一下如何把这不幸的消息告诉 他。
What do you think of the music? 你认为这段音乐怎么样？
5．I don’t think I’ll take it. 我想我不会买。
在英语里， 当think后面的宾语从句含有否定概念，通常形式上否定think，而实际意义上否定宾语从句。如：
I don’t think you’re right. 我认为你不对。
I don’t think she will come. 我认为她不会来。
6. That’s much too expensive! 这太贵了！
much在此起强调作用。
too, much too 和too much
too用在形容词或副此前，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. 这本书对于一年级学生太难。
much too 的中心词是too, much修饰too,用以加强语气，如：
You are much too kind to me. 你对我实在太好了。
The shirt is much too expensive. 这件衬衫实在太贵了。
too much的中心词是much, too修饰much,以加强语气。too much修饰不可数名词，意为 “more than enough”与too many相对，后者修饰可署名词。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. 房间里的烟太多。
7．next week 和the next week
next week与一般将来时连用；the next week(the following week)与一般过去是或一般过去将来时连用。如：
We’ are going to plant trees next week. 瞎周我们将要去种树。
They had a maths test the next week. 第二周，他们考了数学。
8．because,since, as 和for
because是从属连词，它引导的原因状语从句标志介的与哦明确的原因活力有，语气较强，如不说，则不为人们所知。它多用于主句之后。如：
She didn’t come to school yesterday because she had a high fever.
她昨天因发烧没来上学。
as和since也是从属连词， 表示已为们所知或显而易见的原因或理由。 as连句since连句多用于主句前。如：
As(Since) you are not feeling well, better stay home.
既然你不太舒服，还是留在家里吧。
Since everybody is here, let’s begin our meeting.
既然大家都到了，我们就开会吧。
for是并列连词，引导一个并列句，语气最弱，表示一种补充说明，即使不说人们也能知道其原因。它引导的分句只能位于后面，不能位于句首。如：
I had to stop for a rest.,for I was too tired. 我只好停下来休息一下，因为我太累了。
9．either的用法
形容词或代词“二者之一，二者任一”
1)用作代词时，可单独使用，也可以和表示范围的of短语连用，of后的名词一般为附属，并且是特指。如：
Has either of your parents visited you? 你父亲或母亲来看过你吗？
2)用作形容词，修饰单数可数名词，“两个中任一”，其谓语应是单数形式。如；
Come on Tuesday or Wednesday, Either day is Ok.
星期二活性其三来吧，这两天哪一天都行。
Either way will do. 这两种方法哪一种都行。
3)用作副词时，“也（不）”用于否定句，与too相对，后者用于肯定句。如：
If you don’t go, I won’t ,either. 如果你不去，我也不去。
4)either…or…可表示两种可能，意为“不是……就是……”; “或者……,或者……”,连接两个并列成分或并列分句。如：
You may come either before class or after class. 你可以课前或课后来找我。
either…or…连接两个主语时，其谓语应与后面的主语在数上保持一致。neither…nor…,和 not only…but also…连接两个主语时也是这个情况。如：
Either you or I am to go. 不是你去，就是我去。
Neither you nor he is right. 你和他都错了。
Not only you but also your teacher was wrong. 不但你们，而且你们的老师也都错了。
10．They were so pleased to see each other that they forgot everything else.
他们相互见面时如此高兴以至于把别的事都忘了。
so是副词，在其后跟形容词或副词+that引出结果状语从句，表示“如此……以至……”如：
He spoke so fast that I could not understand him. 他说的这样快，我听不懂他的话。
如果so前面是系动词be, become, feel等，那么so后面一般跟形容词，如：
He became so angry that he couldn’t speak. 他气的话都说不出来了。
She was so happy that she danced. 他高兴的跳起舞来。
如果so的前面是实义动词，那么so后面跟副词。如：
He ran so quickly that he won the race. 他跑得非常快，以致于赢得这场比赛。
