八年级英语上册 Unit 5《Relationships》教案和练习1 北师大版.doc

2011-2012学年8年级英语（北师大版）上册（含教案和练习）Unit 5 Relationships（1）
一. 教学内容：
第五单元 第一部分 初步学会陈述做某事的理由及目的
二. 教学重点和难点：
1. 用两个句型表达抱怨某事、某人的方法。
2. 修饰性副词的使用。
3. 要点解析。
三. 具体内容：
（一）enough
1. enough修饰形容词或副词时必须位于被修饰的词语之后。修饰名词时一般位于其前，也可位于其后。enough后面通常接不定式短语或介词for短语。
e.g. The question is easy enough.
Tom didn’t do his homework carefully enough.
The water is cool enough to drink.
We have enough tickets for all of you.
2. 修饰形容词时，如果用于否定句，则否定句在否定enough的同时，也否定了其后的不定式。
e.g He is not careful enough to do the work.
She is not old enough to go to school.
enough如果修饰名词，用于否定句时，不定式没有被否定之意。
e.g. There were not enough people to pick the apples.
3. enough也可以做代词，意思是“足够，充足”。
e.g. We have enough to do to complete the project.

（二）too…to…
too+形容词或副词+(for sb.)+to do 表示“太……以至于不能……”，不定式虽然是肯定形式，但与前面的搭配构成了否定的含义。
e.g. The book is too difficult for you to read.
She is too short to catch the apples on the tree.
在too…to结构中，too前面用了never这个词，则动词不定式可以把否定变为肯定。
e.g It’s never too old to learn.

（三）修饰性副词
根据汉语意思，选择恰当的修饰性副词。
1. a bit, really
(1) These trousers are tight.
(2) I’m sorry.
2. rather, at all
(1) She fell and hurt her leg badly.
(2) They are not friendly to me .
3. a little, extremely
(1) She is absent-minded.
(2) Mary found it difficult to get a job.
通过上面的测试，我们可以得出这样的结论：
（1）rather, a bit, a little 可减轻形容词的绝对性。
（2）really, extremely, quite 可起到强化形容词的作用。
（3）at all用于否定句加强语气。

（四）要点解析及例题
1. seem像是，似乎
seem +（to be ）+表语 seem +to+v. It seems+(that)从句
e.g. It seems that I can’t win.
两种否定式为
They don’t seem to like him.
They seem not to like him.
seem 与look
seem 暗示有一定根据的判断，这种判断往往接近事实。
look 着重由视觉得出的印象。
例 There to be no need to go now.
A. seems B. looks C. is D. are
2. until 直到……为止
（1）肯定句中与延续动词连用。
e.g. I shall stay here until next Sunday.
（2）否定句中与短暂性动词连用。
e.g. He didn’t come until late in the night.
例 I knew nothing about it my friend told me yesterday.
A. because B. since C. until D. so
3. Do you find it easy to deal with plans that change?
find it easy to deal with …中的it在句中做形式宾语，其真正宾语是后面的动词不定式短语。
e.g. They found it hard to walk there.
例 I find difficult to learn English well.
A. it B. that C. this D. them
4. lonely
（1）孤单的，寂寞的，在句中常做表语。
e.g. Tom feels lonely every day.
（2）lonely作“荒凉”讲时，常做定语，修饰地点。
e.g. He lives in a lonely village.
alone 独自的，单独的，在句中常作表语。lonely带有强烈的情感色彩，表示因缺少朋友、友谊而产生的一种悲伤和忧郁的感情；而alone只是陈述一个事实，表示一个人。
e.g. He was alone in the room.
I was alone, but I don’t feel lonely.
The children often come to see Grandpa Zhang, so he doesn’t feel .
A. alone B. lonely C. happy D. happily
