‎________________________________________________________________________‎ Ⅰ.8 reasons for smoking No，not at all dear readers，this article is not meant to promote smoking but to point out several reasons why one would like to smoke.Of course，it is a habit and so repeated over and over again but there are factors behind an individual's smoking habit.‎ Smoking tobacco is now very common even among teenagers and while administrations in the countries are trying to prohibit smoking on the other side they are also aware about the revenues generated each other through tobacco.‎ Let us have a quick look at the reasons for smoking：‎ Few people smoke as they have an idea of feeling masculine.‎ Nicotine has a characteristic of gripping its patient with constant craving for some more.‎ Social gatherings and meetings have also led to increase in smoking.‎ Alcohol and other addictions also support the character of tobacco in giving high.‎ Few people think that smoking a cigarette gives an impression of being carefree.‎ Few smokes due to their burning emotions of heart break.‎ Smoking habit is also found to be given in inheritance by parents.‎ Some diet losers have caught the idea that smoking burns calories and have shunned the bad effects of smoking from their mind.‎ Ⅱ.Smoking hurts mind as well as body Middle－aged adults who smoke tended to perform poorly on tests of memory and reasoning compared to non－smokers，adding to the list of reasons not to smoke，French researchers said on Monday.‎ Analyzing previously collected data on about 5000 British civil servants，the researchers found those who smoked were more likely than people who never smoked to be in the lowest－performing of five groups in tests of memory，reasoning，vocabulary and verbal fluency.‎ Smoking was associated with mental decline in middle age，as it is with dementia and a host of physical ills later in life，they found.‎ ‎“Smoking in middle age is associated with memory deficit and decline in reasoning abilities，” concluded Severine Sabia and colleagues from the National Institute of Health and Medical Research in Villejuif，France.‎ Compared to smokers，people who said they had quit cigarettes were more likely to adopt healthier behaviors，such as drinking less alcohol，being more physically active，and eating more fruit and vegetables，Sabia reported in the journal Archives of Internal.‎ The participants were aged 35 to 55 at the beginning of the study，which followed some subjects up to 17 years.‎ The study also demonstrated how difficult it can be to conduct long－term research on smokers：more than twice as many smokers as non－smokers refused to take the memory test again or were not able to be re－tested，in some cases because they died in the interim.‎ Period

important：abuse，effect，disappointed，stress，ban，desperate，ashamed，automatic，mental，strengthen，due to，feel like，in spite of，take risks(a risk)，get into，decide on.They are all very useful and important.So are the sentence patterns “I didn't know，for example，that it could do terrible damage to your heart and lungs or that it was more difficult for smoking couples to become pregnant.”

‎________________________________________________________________________‎ ‎________________________________________________________________________‎ Period 3　Grammar—the Use of “It”(1)‎ 教学内容分析　　　‎ This teaching period mainly deals with the grammar：the use of “it”．The impersonal pronoun “it” is used frequently in English and has many different functions.“It” can be used in the subject or object position，to stand for an infinitive，－ing form or a clause.The impersonal pronoun “it” can be used to talk about time，distance，weather，etc.“It” can also be used for emphasis.‎ In this period we will focus on only part of its usages，that is，the use of “it” when the subject of a sentence is a clause，an infinitive，or the －ing form.‎ 三维目标设计　　　‎ Knowledge and skills ‎1．To let the students learn the use of “it”．‎ ‎2．To enable the students to use “it” correctly and properly.‎ Process and methods ‎1．To ask the students to read the reading passage again，pick out the sentences with the word “it” in

enough to cycle 20 kilometres in an afternoon.‎ ‎(3)Your mother tells me that you started smoking some time ago and now you are finding it difficult to give it up.‎ ‎(4)It might help you to stop and strengthen your resolve.‎ Ask the students to think about the use of “it” according to the above four sentences.‎ Step 3　Grammar learning Ask the students to study the following sentences and try to summarize the structure and usages of“it”．‎ ‎1．The personal pronoun “it” and the impersonal pronoun “it”．‎ ‎(1)Tom's mother kept telling him that he should work harder but it didn't help.‎ ‎(2)—Who is knocking at the door?‎ ‎—It's me.‎ ‎(3)It's about five kilometers from here to the railway station.‎ ‎(4)It's getting colder and colder every day.‎ ‎2．“It” is used in the subject or object position.‎

individually，and then let them discuss and check their answers with their partners，and finally give them the correct answers and deal with any problems they might meet.‎ Step 6　Getting more about the grammar ‎1．it作形式主语的几种句型 ‎①It＋be＋形容词/名词(difficult/necessary/a rule/a duty)＋for/of＋sb.to do sth.‎ ‎②It＋be＋形容词/名词(difficult/necessary/a rule/a duty)＋that clause ‎③It＋be＋过去分词(said/reported/known)＋that clause ‎④It＋be＋形容词/名词(useless/no use/no good)＋doing ‎⑤It＋takes sb.some time＋to do sth.‎ ‎⑥It＋seems/appears＋that clause ‎⑦It＋seems/appears＋as if clause ‎2．it作形式宾语的特殊用法。某些及物动词或短语不能加宾语从句，此时须先用it作形式宾语，然后接宾语从句。此种用法常用于like，dislike，hate，appreciate，depend on，see to等后。如：‎ I hate it when people talk with their mouths full.‎ You may depend on it that they will support you.‎ I'll appreciate it if you close the door for me.‎ I like it in the autumn when the weather is clear and bright.‎ ‎3．it 引起的几个易混的时间句型 ‎1)It's time for sb.to do sth.和It's(about/high) time that sb.did sth.(should do sth.)。例如：‎ It's time for us to go to bed.‎ It's(about/high)time that we went/should go to bed.‎ 注意：It's (about/high) time

sth.和It was years/days/weeks since sb.had done sth.例如：‎ ‎—What was the party like?‎ ‎—Wonderful.It's years since I enjoyed myself so much.‎ It was years since I had began to learn English.‎ ‎(5)It is/was＋具体时间点＋when clause。例如：‎ It's 6 o'clock when I go home from school every day.[来源:学,科,网]‎ It was five o'clock when they finished the job.‎ 注意：在本结构中，when引导的从句是定语从句，具体时间点是先行词。‎ Step 7　Summing up Try to help the students draw the following conclusions.‎ ‎1．There are many sentence patterns in English with “it” in them.“It” has many functions.‎ ‎2．When “it” acts as a subject or an object，the real subject or object can appear in the form of an infinitive，－ing form or a clause.The impersonal pronoun “it” can be used to talk about time，distance，weather，etc.‎ Step 8　Playing a game ‎1．Get students to form groups of 6.‎ ‎2．Let students play the game “What is it？”．Spend some time making up clues to identify several objects/illnesses/habits in this unit.Then read your clues to your partner and see if he/she can identify them.Choose the best ones to read to the class.‎ EXAMPLES：‎ It is a bad habit for both males and females.‎ It is something you shouldn't start because you will

‎________________________________________________________________________‎ Ⅰ.Three Powerful Steps to Relieve Stress Step 1　Exercise Taking time to exercise will not only improve your body and its physical appearance，it will assist in releasing the stress hormones that have been building up.A daily vigorous walk，jogging，weight lifting，aerobics，swimming，bike riding，dancing or a dance class，football，basketball，etc.are all great ways to relieve the chemical stress hormones.‎ Step 2　Eating Right[来源:Zxxk.Com]‎ Eating a balanced diet will not only make you feel better it will relieve some of the stress and certainly won't add to it.When you eat a diet high in sugars，cholesterol，and fat，you add to the trauma in your system.Concentrate on a high protein，veggie，fruit diet and you will see remarkable improvements.Also whole grains promote production of the brain neurotransmitter serotonin for a greater sense of well－being.When you combine healthier eating with exercise your body will respond favorably and the stress levels will start to decrease.‎ Step 3　Change Your Mindset If you walk around all day saying “I'm so stressed”，you will be.Positive thinking is crucial to relieving the mental stress.Our minds are so powerful that we can actually increase our stress by the way we think and the things we speak.If you develop a new mindset that is positive in nature and optimistic，studies have shown this to be a reliever of stress.Meditation is a prime way to change your mindset and refocus on the positives and what is really important.Try yoga or visualization imagery to assist.‎ Ⅱ.Reasons Why People Find Relief in Smoking Smoking is a harmful habit and makes one addicted once they start doing it.However，what are the reasons why people still continue to smoke？These people know the harmful and if long term，even life threatening effects of smoking but it seems nobody heeds the warning.‎ The number of teenagers smoking today has increased tremendously.Their parents do their best to stop them from starting the habit；however，most of them are unsuccessful.Teenagers experience a feeling of isolation.It is the time that they are confused which role to take in society.Most of them usually have identity crisis at this age and smoking makes them feel better.Once they start smoking，they soon love the feeling of contentment it brings them.Thus，they continue doing it.Peer pressure is also a great factor to this.A teenager would like to belong to a group.Being alone and no friends when you are a teenager is hard.Having some people to support you and accompany you in any social activity feels great.At this stage，teenagers feel their parents don't understand them.Everything that their parents tell them and do is against their will.They still can't understand all the things their parents are doing for them which are for their own good.Those who are non－smokers are often convinced by smokers to engage in this activity.Usually，they would smoke and drink overnight.Teenagers feel that if they won't join the group，they would lose their friends and will be left alone in which they don't want to happen.This is the reason why they continue smoking to be accepted by them.Later in life when they finally decide to stop，it becomes hard as they are already addicted to it.‎ There are also some people who smoke because of the nature of their jobs.Those who work in a very cold area or at sea smoke to keep their bodies warm.At this time，smoking brings them good benefits.Call center agents and those who work at night love drinking their favorite cup of ‎ coffee and smoking at the same time while waiting for their shift at work.This is to keep them awake and attentive to answering their clients and finishing their assigned task.However，they don't consider the long term ill effects of smoking.Smoking is addictive.[来源:Z。xx。k.Com]‎ Smokers are also those who are experiencing feelings of depression.They find it hard to face the challenges life brings most especially if their problems are too hard to handle.They feel that what can make them feel better is by smoking and drinking.Yes，it is true that smoking could make them feel better but it is just a temporary feeling of relief.‎ Period 5　Reading and Writing 教学内容分析　　　‎ The teaching materials of this period contain two parts.The first part is the reading passage on Page 22 titled HIV/AIDS：Are You at Risk? which is about what is HIV/AIDS，how it is contacted and how to protect oneself from getting the disease.The second part is the writing task on Page 24，which asks the students to write a letter to Li Xiaolei to give her some advice on her problems.‎ 三维目标设计　　　‎ Knowledge and skills ‎1．To enable the students to know something about what is HIV/AIDS，how it is contacted and how to protect oneself from getting the disease.‎ ‎2．To get the students to learn the following useful new words and

HIV/AIDS are 15－24 years of age.More than 7 million people in Asia and the Pacific are living with HIV/AIDS.‎ Step 3　Pre－reading[来源:学,科,网][来源:学#科#网Z#X#X#K]‎ It is likely that many students have incorrect information about the disease，so teachers should first get students to talk about something about HIV/AIDS by asking the following questions：Can ordinary people be at the risk of contracting HIV？In what way can people get infected？What measures can people take to protect themselves？Will people die if they have HIV?‎ Step 4　Fast reading This passage can be divided into three sections.Scan

infected，blood or sexual fluid that carries the virus，has to get inside the body through broken skin，or injection.(P22)‎ 携带病毒的血液或体液必须通过皮肤上的创口或通过注射才能进入人体，使人受感染。‎ 句中有一个that引导的定语从句，修饰blood or sexual fluid；to become infected是不定式短语作person的后置定语。‎ ‎4．Here are some things you can do to make sure you stay safe.(P22)‎ 你可以按照这里列举的一些注意事项去做，以确保自己安全。‎ things后跟了一个定语从句you can do；动词不定式短语to make sure you stay safe表示目的，make sure后接宾语从句you stay safe，省略了连接词that，stay 在此处是一个系动词，意为“保持”，后接形容词。例如：‎ They are going to stay awake to see the lunar eclipse.‎ 他们打算不睡觉等着看月食。‎ ‎5．It is only when the disease has progressed to AIDS that a person begins to look sick.(P22)‎ 只有当这种病发展成艾滋病时，人才会显出病态。 ‎ It is/was...that/who...是强调结构，它可以用来强调句中的某些成分，如主语、宾语、状语等，但不能用来强调谓语和表语。原句是： A person begins to look sick when the disease has progressed to AIDS.‎ ‎6．Women are slightly more likely to become infected than men.(P22)‎ 女性感染病毒的可能性比男性稍微大一些。‎ be likely 后接不定式或从句，表示“可能会……”。如：‎ He's likely to arrive late this afternoon.‎ 他今天下午可能会迟到一会儿。‎ It's likely that they will camp out tonight.‎ 他们今天晚上可能要在外面露营了。‎ Step 8　Writing ‎ ‎1．Read this letter and imagine you are Wang Ping，the adviser who deals with students' problems.Write a letter to give Li Hua some helpful advice.‎ Dear Wang Ping，‎ Can you help me，please？I have tried to stop smoking several times.I am OK for two days and then I feel really sick and irritable and I have to start smoking again.I know smoking is a bad habit，but I just can't seem to give it up.Do you have any useful tips?‎ Yours sincerely，‎ Li Hua ‎2．Before the students write the passage，guide them to do the following things.‎ ‎(1)Help students decide the tense of the letter.‎ ‎(2)Ask them to note down 3－5 tips they would like to include in their letter.‎ ‎(3)Let them discuss with each other how they will organize their letter.‎ One possible version：‎ Dear Li Hua，‎ I am sorry you have had so much trouble to stop smoking，but I am glad you are still trying.I hope the tips below will help you.‎ First of all，don't give up.The more often you try，the more likely you are to eventually succeed.When you feel irritable，don't automatically reach for a cigarette to make you feel better.Take a few moments to relax.Start by breathing deeply and lifting your arms out to the side and over your head.‎ It is a good idea to drink lots of water and eat lots of fruit when you are quitting smoking.This will help to remove the nicotine from your body faster and you won't feel so sick.It is normal to feel a little stressed when you first give up smoking，but try to remember that it will only last a few days and then you will begin to feel much better.[来源:学.科.网]‎ Keep up the good work，Li Hua，and remind yourself how much healthier you will be when you finally quit.‎ Good luck and best wishes!‎ Yours
