Step 1 Lead in
Talk about it!
What are your strong points and weak points
Did you ever write to a doctor or another person for help
Step 2 Listening
Listen to the tape and answer the questions below.
1. What does the letter come from
A sad girl from Washington.
2. What does she feel about herself
She feels bad about herself.
3. How many advice does Sue give the sad girl

2. Who is Lisa What does the sad girl say about her
3. Is anyone perfect in this world
4. What’s the important thing when we make mistakes
5. What do you think of Sue’s advice
Step 4 Language Points
1. My friend Lisa, however, is pretty and smart. 然而,我的朋友丽萨,既聪明又漂亮。
however 意为“可是,然而,尽管冶,较but 的意味弱。其位置可以在句首,句末或插入句中。当其被用来对照两个分句时,中间需要有一个逗号;当它被用作句子的插入语时,则前后应各有一个逗号。
如：His friends,however,had other ideas. 然而他的朋友们却另有见解。
【拓展】(1)but 作为并列连词,在意义上起转折作用。but 前后的两个句子或短语在意义上形成鲜明对照。but 用来连接两个
分句或两个较长的短语时, but 前面一般要加逗号。
如：He is old but strong. 他年纪虽大却很强壮。
Learning the guitar isn蒺t difficult, but you will have to practice.
学弹吉他并不难,但是你得练习。
(2)and 作并列连词,用来连接两个相同的句子成分。这两个
句子成分可以是单词、短语或分句。and 连接两个分句时,
分句本身都有自己的主语。如果第二个分句的主语与第一个分句的主语相同,则第二个分句中的主语可以省略。
如：When and where were you born 你出生在何时何地
John and Tom are our good friends. 约翰和汤姆都是我们的好朋友。
2. I get average grades in all of my subjects except English.
我所有的学科都得平均分，除了英语。
【辨析】except, except for与besides
(1)except意为“除……之外(没有……)”，着重强调在同类人或物中除去一个或几个，表示一种排除关系，有“减除”之意。如：
All the other five representatives arrived late except me.
除了我，其他的五位代表都来晚了。(晚到的代表中不包括“我”)
(2)except for意为“除了……”，except是指排除同类，而except for是指排除非同类，常在说明基本情况后，从细节上加以修正。如：
The movie was good except for the ending.
这部电影除了结尾之外都很好。
(3)besides意为“除了……(还有……)”，指在整体中加入一部分，表示一种累加关系，besides后的内容包含在所述情况内，常与other连用。如：
Five other representatives arrived late besides me.
除了我，还有五位代表来晚了。(晚到的代表中包括“我”)
【提醒】but与except的用法基本相同并常互换使用，但but着重强调整句的内容，且习惯上用于every/all/any/nothing/no/who 等词后。如：
She could do nothing but crying.
她除了哭没有别的办法。
3. impossible adj. 不可能的
【点拨】impossible是否定前缀im-加形容词possible构成的。英语中某些形容词加否定前缀im-，in-，un-等构成新词表示否定意义，如unselfish无私的，inadequate不充分的。如：
It’s impossible to finish the work in two hours.
在两个小时之内完成这项工作是不可能的。
4. The important thing is to learn from your mistakes. 最重要的是要从失败中吸取教训。
动词不定式短语：to learn from your mistakes 该短语在句子中作表语。
如：His work is to drive a car. 他的工作是开车。
My job is to feed animals. 我的工作是饲养动物。
Her ambition is to be a doctor. 她的理想是当一名医生。
【拓展】不定式除了可作表语外,还可在句中作主语、宾语、状语、宾语补足语和后置定语。
如：To see is to believe. 眼见为实。(作主语)
After class the students stopped to have a rest. 课后,同学们停下来去休息。(作宾语)
He ran so fast as to catch the first bus. 他飞快地跑以便赶上第一班公交车。(作状语)
He asked me to talk about English study. 他让我谈谈英语学习。(作宾语补足语)
Zhang Jian is the first to swim across the river. 张健是第一个游过这条河的人。(作后置定语)
