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．

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．
