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。”Lai 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(優先權)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．

(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．

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．)

(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．

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：Well done．Now，please turn to Page 56．Look at Part 4．You are asked to draw a timeline of your life and mark the best times(the highs)and the worst times(the lows)．Then write down sentences to tell what some events that made you very happy were, what made you so sad，and what some points were in your life when you made a change or learnt an important lesson．You can referring to the following example．Are you clear?

Ss：Yes．

(The students begin to do it．After that，teacher says the following to go on will the next part．)

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 “licence” 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．
