I．Brief Statements Based on the Unit
This unit mainly talks about deadly diseases and attitudes towards AIDS，cancers，
etc．A11 the activities，including Warming up，Listening，speaking，reading and writing，center on this topic．Through this topic，the students not only get more information about diseases，but also learn how to keep a right and positive attitude towards diseases and people with diseases．
In addition，the students can 1earn some useful language points through the materials provided in each part，especially a lot of words and phrases，which are very helpful for the students to build up vocabulary about diseases．The Grammar--the Subjunctive Mood is also important．The given materials and exercises give the students an opportunity to learn grammar by using it．It helps the students learn to talk about things t}lat are not certain to happen as well as imaginary or unreal events and situations．
All of the activities are helpful for the students to improve their knowledge about 1anguage and their skills to use language．
Ⅱ．Teaching Goals
1.Talk about deadly diseases and attitudes towards AIDS，cancers，etc．
2.Practise talking about imaginary situations．
3.Practise supporting and challenging an opinion．
4.Learn to use the Subjunctive M00d(1)：lf 1 were you，…I Wish I could…
5.Write a personal narrative．
Ⅲ．Teaching Time：Four periods
Ⅳ．Background Information
1．Health Officials Struggle to Understand SARS Sever acute respiratory syndrome (SARS) has terrified the world．The question on everybody’s mind is whether SARS will become a global epidemic．
Researchers worldwide have galvanized to combat SARS．The challenge for public
health is to determine the nature and potential of any viral threat and to frame a battle plan．
“We are in an evolutionary stage of this epidemic，”said Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases in Bethesda，Maryland. “It could plateau，go up and down，disappear of explode．This virus is highly virulent，potentially lethal and highly transmissible--it has the potential to cause a really bad epidemic．”
A Deadly Combination
SARS is a so-called hybrid virus-the kind that always triggers a red alert．Traditionally a virus affects a single species．But sometimes two viruses combine their genetic material and form a new virus that“ jumps” to another species altogether．
Hybrids are dangerous because the body has never encountered them before，and the immune system is unprepared．
“From studying the sequence we see that the SARS virus is derived from a mouse coronavirus and an avian coronavirus，”said Michael Lai，a pioneer in coronavirus genetics at the University of Southern California in Los Angeles．
If the virus exists in a wild widespread host--like the West Nile virus carried by mosquitoes-then SARS could be a perennia11y recurring problem, according to Lai．
If the host is a domestic animal一like the chicken responsible for the Avian F1u virus of 1997--then the source of the virus could be eliminated．The Avian Flu effectively stopped after the Hong Kong government ordered the slaughter of chickens in the area．
Lai suspects that the SARS virus lurks in a wild animals. “It probably doesn’t bother domestic animals or we would have come across it before，”he said．
1f people are the only carriers of SARS，“honest reporting of SARS cases and stringent quarantines could stop the virus in its tracks ,”Lai said．
Knowing a Virus，Predicting an Epidemic
“Making a vaccine could be quite straightforward，if it is needed�！盠ai said．
Vaccines already exist for swine and chicken coronaviruses. But it isn’t easy to gauge whether SARS，or any virus．can trigger an epidemic．
“We’ve been working with influenza for over 50 years and it can sti1l evade our best attempts．”
“In many cases of the influenza virus we don’t understand the molecular properties that cause high mortality，”said Nancy Cox， chief of the influenza branch at the CDC．
“Outbreaks are like wildfires，”Morse said．“Some fires smolder and are easily extinguished．Others rage out of control，destroying everything in their path．The WHO and the CDC are like the fire department and they need to investigate all outbreaks because you never know which way they could go．”
Morse points out our long history with influenza．SARS is only a few months old．
Tracking and containing viruses，and predicting what they will do，Morse said，“It is as much an evolving science as an evolving art．”
2．Fight Continues Against HIV／AIDS
A picture，a calendar or even a balloon may be the best way for millions of people living in China’s vast country areas to learn about AIDS，one of the biggest threats to public health in the world today．
China has decided to use user-friendly methods including exhibitions, VCDs and TV programmes to spread knowledge of the disease across the nation to try to keep it in check．
Educating people nationwide about AIDS is the top priority(優(yōu)先權(quán))to prevent
the disease from getting out of hand．The farmers wil1 be given knowledge in the easiest way that they can understand．
A recent survey from the commission(調(diào)查團)of more than 7 OOO people in China
showed that nearly 20 percent of them had never heard of AIDS before．Just over 71 percent said they knew AIDS was highly infectious(傳染的),but most of them had no clear idea of how the disease could be spread．Just over 62 percent said they knew they could do things in advance to prevent them catching AIDS but they didn’t know what these measures were．
The month-long survey，carried out last December，talked to people in seven counties and cities across China including both developed coastal areas and the less-developed in-land areas．The interviewees changed from 15 to 49 years old，and country residents were about 63％ of the total surveyed．
Chinese residents，especially those in the country，have very little knowledge about what AIDS is all about，not to mention prevention and treatment．By the end of last year, there were 22 517 known HIV／AIDS cases in China．However，more than 6000000 people in China have been infected．
Since 1985，China has discovered 880 patients with AIDS一466 of them have died．
Sharing needles，prostitution(賣淫)and contaminated blood transfusions are major ways for HIV to spread．A lack of education has been the biggest difficulty against nationwide efforts to prevent AIDS，especially in the countryside．

T：Are you ready?
Ss：Yes．
T：Who’d like to tell the difference between AIDS and HIV?
S1：Let me have a try．HIV is the virus that caused AIDS．AIDS is a kind of incurable disease．People get AIDS after having been infected with HIV virus．
T：Thank you．Sit down．In what way does AIDS spread? Any volunteer?
S2：AIDS spreads through b1ood and other body liquids．People transmit HIV by having unprotected sex，by receiving infected b1ood transfusions or through birth．
T：Well done．Now 1et’s learn some useful phrases in the text．Look at the screen．
(Teacher shows the screen and gives brief explanations．)
1. break down：cause sth．to collapse；destroy sth．
e．g．How can we break down the barriers of fear and hostility which divide the two communities ?
2．a(chǎn) 1ack of：absence or shortage(of sth. that is needed)
e．g．The poor girl felt 1onely because of a 1ack of care．
The project had to be abandoned for? lack of funds．
3．cheer(…)up：(cause sb．to)become happier or more cheerful
e．g．Try and cheer up a bit；life isn’t that bad!

(Bb：break down，a lack of，cheer(…)up，suffer from, deal with)
(After explaining the phrases，teacher says the following．)
T：So much for the phrases．If you still have any difficulty in understanding the text，you can ask me．
S：Why in some sentences “were” is used after “I” and “she”，especially after“ I wish”，“as if ”and “if”?
T：Oh, you are careful．I'1l explain to you．Here “were ”is used as the subjunctive form to talk about events and situations which are not certain to hap-pen--which we hope will happen，or imagine might happen or want to hap-pen．For example, the sentence “I wish I could remember more about my mum．”means “It is a great pity that I don’t remember much about my mum．”The sentence “If I were to live long enough to have a job，I would choose to be a doctor，helping these AIDS patients “means” I want to become a doctor, helping these AIDS patients, but I can’t, because l won’t live long enough to have a job．”The sentence“…not act as if I were a bad or dangerous person．”means “I hope people don’t treat me as a bad or dangerous person．”1s that clear?
Ss：Yes．
T：Well, now please listen to the tape and try to understand it further．Then read it aloud for a while and talks about these two questions on the screen in groups of four．
(Teacher shows the questions on the screen．)
1．How do you think you would react if you were Xiao Hua?
2．How should we act towards people who have AIDS What can we do to help them?
(After the students listen to the tape and talk about the questions for a few minutes, teacher asks some students to give their opinions．)
T：Well，stop．Who’d like to give us your opinion about the first question? Volunteers?
S1：If I were Xiao Hua，I might be discouraged，but after l read the story about her，l think l should try to live 1ike her and do some meaningful things for the AIDS patients and the society．
S2：If 1 were Xiao Hua．I think 1 would appreciate every minutes of each day before my death and leave my smiles to my friends and patients．
S3：…
…
T：What about the second question?
S4：We should not have the wrong attitude towards people who have AIDS．Don’t consider them as bad and dangerous persons and look down upon them．On the contrary，we should try our best to help them and care about them．We can help to spread the knowledge about AIDS, such as the major ways for HIV to spread and prevention and treatment treasures. This way, AIDS patients would feel less lonely and more people can be prevented from being infected.
S5：…
…
T：You all did very well．Thank you．Sit down，please．
Step V Summary and Homework
T：In this class，we’ve not only learned more about AIDS, but also 1earnt how to act towards people who have A1DS．We should call on a11 the people to fight against AIDS．Besides, we’ve 1earned some useful words and phrases as well as some useful structures with the Subjunctive Mood used in it．After class，please read the text more times to make sure you’ve really understood it and master the useful language points．

Step ⅡRevision and Lead-in
T：Yesterday，we read a passage about an AIDS patient named Xiao Hua．Can you tell the story about her?
Ss：Yes．
T：Any volunteer?
S：I wi11 try．Xiao Hua is fifteen and lives in a province in Southern China．Her mother contracted the HIV virus when she was twenty-eight，and she died of AIDS only three years after Xiao Hua was born．Unluckily，Xiao Hua was born dying with AIDS．Although she has her father，who is also infected with AIDS, to take care of her, they cannot afford the drugs to treat her illness．Xiao Hua knows that she will die before she has a chance to grow o1d, but she does not let that knowledge discourage her. Instead，she decided to use the limited time she has left to do something to help others．She not only help people learn more about how to protect themselves, but also persuade people to show care and love to AIDS patients．She makes her life happy and beautiful．
T：Thank you．Sit down，please．Besides, we’ve learnt some useful words and sentence structures in it．Today we’11 practise using them．Now，let’s learn the new words in this period．Look at the screen．
(Teacher shows the screen and deals with the words briefly．)
△visible／′vIz bl／adj.
△defensive／dI′fensIv／adj．
identify／al′dentIfaI／vt．
stranger／′streIndз (r)／n．
meaningful／′mi：nIηfl／adj．
boyfriend／′boIfrend／n．
bi11ionaire／bIlj ′ne (r)／n．
Step Ⅲ Word Study
T：Well，now please open your books at Page 52, Look at the first part--Word study．Choose the right word in each sentence．Turn to next page and let’s study the example．“visible” and “invisible”，which are opposite in meaning，are given in the bracket．The prefix “in一”gives a negative meaning．According to the meaning of the given sentence．“invisible” is chosen. Have you understood the example?(Bb： visible-invisible)
Ss：Yes．
T：In the following sentences，some other pairs of opposites are given in the brackets．Now please work in pairs to choose the proper word for each sentence．After a while, I will check your answers．
Suggested answers：
1．infected with 2．incurable
3．imaginary 4.defenseless
(Teacher writes each pair of opposite on the blackboard．)
T：Well done．Now it’s your turn to make sentences．Look at the next part．Four pairs or opposites are listed．You are asked to use one of each pair of the words to make your own sentences. Then show them to your partner and correct each other’s errors．Are you clear?
Ss：Yes．
Suggested sentences：
1．1n winter, plants should be protected from the cold．
The so1diers were unprotected against the enemy’s surprise attacks．
2．He said something proper for the occasion. Laughing and joking are considered improper behaviour at a funeral．
3．She was suffering from a headache．
She enjoys listening to music．
4．Our teacher encouraged us to speak English in class．
Don't discourage her；she’s doing her best．
(Bb：protected／unprotected；proper／improper；suffer／enjoy；encourage／discourage)
T：Next，1ook at the third part．Read the following sentences and try to find a word from the text to complete each sentence．Study the example first, Then finish your work individually．At the end，check your answers with your partner and correct mistakes．
Suggested answers：
1．persuaded 2．patients
3．drugs 4．infected
5．suffering 6．cure
7．contracted 8．virus
Step IV Grammar
T：Well，so much for Word study．1n the text about Xiao Hua, we’ve also learnt some sentences in the Subjunctive Mood．Now please look at the sentences on the screen．
l．I wish I could remember more about my mum．
2．I wish she were here with me and that we weren’t sick．
3．I wish people would find out the facts and not act as if I were a bad or dangerous person．
4．If I were you，I would give an AIDS patient a hug．
5．If I had HIV，I would know because I would feel sick．
Pay attention to the underlined parts．We can see the Subjunctive Mood in each sentence is expressed with a special verb-form．For example，after “wish ”and “as if”, a past tense is used to express a present meaning，“would +an infinitive ”to express a future meaning．Is that so?
Ss：Yes．
T：Then what about the verb form after “if ”?
Ss：The past tense is used in the if-clause and “would +an infinitive ”is used in the main clause to express a present or future meaning．
T：Quite right．And we should remember the Subjunctive form “were” is often used instead of “was”； “was ”is possible more common in conversational English．Are you clear?
Ss：Yes．
(Bb：I wish…；…as if…；lf I were…，…)
T：A11 right．Now please write sentences to explain the sentences on the screen． For example, the first sentence “I wish I could… ”means “It is a great pity that I don’t remember much about my mum．”Can you understand?
Ss：Yes．
T：OK．Now please prepare for a while. Then I’ll check your work．
Suggested answers：
2．It is a great pity that she is not here with me but died of AIDS and that I’m sick，too．
3．I want people to find out the facts and not consider me as a bad or dangerous person．
4．I suggest that you give an AIDS patient a hug．
5．Imagine that I have HIV．I will know because I wi11 feel sick．
T：Well done! Now，please 1ook at the pictures in our books and make wishes using the Subjunctive Mood．
Suggested answers：
① I wish I would become an engineer．
② I wish I were one of the stars in the sky．
③ I wish I could get a big house．
(Then teacher asks the students to finish the rest of the parts in Grammar, First individually．Then check in pairs．At the end，teacher asks some students to read their answers and check with the whole class．)
Suggested answers：
Part 3：1．I wish I could solve my problems．
2．I wish I had not been working so hard．
3．I wish I could forget the terrible scene．
4．I wish we had enough money．
5．I wish the performance would go well．

(A few minutes later，teacher checks the answers．)
T：OK．Have you found the answers?
Ss：Yes．
T：How is cancer caused? Wang Li，you try，please．
S1：Cancer begins in cells．There are many types of cells in the body and each has a special function．In a healthy body, cells grow and divide to produce new cells only when it necessary．If the production of cells is discupted，cells either divide too fast or at the wrong time，making it difficult for the body to function properly．This way，people got cancer．
T：Very good．Sit down，please．How did cancer change the writer’s 1ife? Volunteer? S2：First，the writer felt empty and hopeless．Then he began to receive treatment and fought against the i11ness, suffering great pain and difficulty．Later，he found the strength to recover with the help of his family and friends. After fourteen months’ successful treatment，he was able to go home．But the cancer in his body has just been defeated for the moment．It can come back at any time and the struggle wil1 never end，so he says his life has not yet ended but really begun．He has changed his attitude towards life．He has learnt to appreciate every minutes of each day．
T：Well done．Now please Listen to the tape of the passage and further under- stand it．At the same time, underline all the useful expressions．

Step Ⅳ Discussion
T：OK．NOW stop reading and let’s have a discussion．Look at the questions on the screen and then work in groups of four．
1．compare the writer’s situation with that of Xiao Hua in the reading passage．How are their experiences similar or different?
2．How do you think your life would change if you found out that you had an incurable disease?
(After the students discuss for a while，teacher asks some students to answer the questions．)
T：OK．Stop discussing．Who’d like to talk about the first question? Any volunteer?
S1：I’ll try it．Both Xiao Hua and the writer got an incurable disease．Neither of them give in to the disease．They both fought against it and try to make their limited lifetime more meaningful．As to the difference between them．Xiao Hua got AIDS through birth．She not only has to suffer from the disease，but also have to deal with people’s fear of the disease，whi1e the writer got cancer because the production of cells in his body is disrupted．Cancer does not spread from one person to another，so he is taken good care of by his family and friends．
T：Quite well，what about the second question? Any volunteer?
S2：Let me have a try．If I found out that I had an incurable disease，I think my life would change as the writer’s life，Because the existence of our life is happiness to our family and friends．

T：OK．Now it’s your turn to write an essay about an important event in your life or another person’s life．First look at the instruction to Writing on Page 56．Then write your own essay．
Failure in the National Examination
University is not the only way to success．Cao Yang who is my neighbour, will never forget the day when he knew the result of the National Examination, by which you could get the “l(fā)icence” to enter the university．However，he lost the opportunity to step into the threshold of the university．At that moment，he felt he nearly callapsed onto the ground and thought the road to his future life was completely b1ocked．
He didn’t want to try it again, because it would cost his family a lot of money，what he most wanted to do at that moment was to go to work as soon as possible．Thus，he could earn enough money to support his family．
The difficulties he encounted in his work made him feel the lack of enough knowledge．From then on，he made up his mind to catch up with updated technology．By fully making use of every minute he could get after work，he immersed himself into study and eventually he became an expert．Later on，when his workmates met with the problems in their work，they all came to him and he could always get them done properly．
Through his efforts，he has made great achievements in his life．He now feels that university is not the only way to success．It was the failure in the National Examination that taught him nobody should shrink back in front of difficulties. On the contrary，we’d better think of it as a precious gift that the God gives us to realise our goals．

Ways to remember and understand new words：
You can put new words into groups to remember and understand them together．For example，some words have similar meaning．1ike cure and heal，both meaning “to make something better”．Others belong to the same category，like AIDS and cancer，which are both diseases．Try to think more ways that you can group new words．
(After that)
T：Now，please 1ook at the following words and phrases on the screen and group them in at least two different categories．
immune，defenseless，infection，cure, contract，virus，suffer，discourage, specialist，lonely，eventually, break down, die of，cheer up，deal with，as if,a lack of
