Passage FiveAustralia is nearly as large as the United States, but most of it is too dry for people to live in. Aroundthis dry part are large sheep and cow farms. A few of them are as large as the smallest states: of America.Often the nearest neighbours are several hundred kilometers away.The two-way radio is very important to people who live on these great Australian farms. It works much like atelephone. A person can listen to someone else talk and then gives an answer. For example, people onthe large farms could talk to a doctor far away. They could tell the doctor about someone who was ill,and the doctor could let them know how to look after the sick person.As the large farms were so far from towns, the children could not go to school. Radio schools werestarted for them in some places. At a certain time each day, boys and girls turn on their radios andlisten to teachers in cities far away.Families on the large farms wanted to give news to their neighbours. The programme Round RobinTalks by radio was started to keep families in touch with each other. They could talk about who wasgoing away and who was iii. The men could talk about their sheep and cows and how much moneythe markets would pay for them. In many ways the radio became a newspaper for the farm people of Australia.52. In the passage "the two-way radio" is______.A. important to AmericansB. useful for children onlyC. used as a telephoneD. only used by doctors

Alcoholism1 .Yes,alcoholism can be treated. Alcoholism treatment programs use both counseling and medication（药物治疗）to help a person stop drinking. Most alcoholics need help to recover from their disease. With support and treatment,many people are able to stop drinking and rebuild their lives.2. A range of medication is used to treat alcoholism. Benzodiazepines（苯二氮平类药物） are sometimes used during the first days after a person stops drinking to help him or her safely withdraw from alcohol. However,these medications are not used beyond the first few days because they may be highly addictive. Other medications help people remain sober（清醒）. One medication used for this purpose is naltrexone（环丙甲经二经吗啡酮) . When combined with counseling,naltrexone can reduce the strong desire for alcohol and help prevent a person from returning to heavy drinking. Another medication, disulfiram（戒酒硫）,discourages drinking by making the person feel sick if he or she drinks alcohol. Though several medications help treat alcoholism,there is no“magic bullet”.Developing new and more effective medications to treat alcoholism remains a high priority for researchers.3 .Alcoholism treatment works for many people. But just like any chronic disease,there are different levels of success in treatment.Some people stop drinking and remain sober. Others cannot stop drinking for any length of time. With treatment,one thing is clear,however,the longer a person stops drinking alcohol,the more likely he or she will be able to stay sober.4 .No,alcoholism cannot be cured at this time. Even if an alcoholic hasn't been drinking for a long time,he or she can still return to the drinking habit.To guard against it,an alcoholic must continue to avoid all alcoholic drinks.For alcoholism treatment,there is no single medication that works______.A: stay confusedB: alcoholic drinksC: medical treatmentD: feel sickE: in every personF: stop drinking

第二篇As we have seen,the focus of medical care in our society has been shifting from curing disease to preventing disease一especially in terms of changing our many unhealthy behaviors,such as poor eating habits,smoking,and failure to exercise.The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight , but does not eat very nutritious（有营养的）foods , who feels OK but exercises only occasionally , who goes to work every day , but is not an outstanding worker,who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts,but sleeps a lot and often feels tired.This person is not ill.He may not even be at risk for any particular disease.But we can imagine that this person could be a lot healthier.The field of medicine has not traditionally distinguished between someone who is merely "not ill" and someone who is in excellent health and pays attention to the body's special needs.Both types have simply been called "well".In recent years,however,some health specialists have begun to apply the terms "well" and "weilness" only to those who are actively striving to maintain and improve their body's condition.Most importantly,perhaps,people who are well take active responsibility for all matters related to their health.Even people who have a physical disease or handicap（缺陷）may be "well" ,in this new sense,if they make an effort to maintain the best possible health they can in the face of their physical limitations."Wellness" may perhaps best be viewed not as a state that people can achieve,but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes.And by focusing attention on healthy ways of living,the concept of weilness can have a beneficial impact on the way in which people face the challenges of daily life.The first paragraph implies that_________.A:good health is more than not being illB:sleeping a lot could be harmfulC:regular health checks are essential to keeping fitD:prevention is more difficult than care

第三篇Look After Your VoiceOften speakers at a meeting experience dry mouths and ask for a glass of water. You can solve the problem by activating the saliva in you mouth.First gently bite the edges of your tongue with your teeth.Or press your entire tongue to the bottom of your mouth and hold it there until the saliva flow.Or you can imagine that you are slicing a big juicy lemon and sucking the juice.Before you begin your talk,be kind to your voice.Avoid milk or creamy drinks which coat your throat.Keep your throat wet by drinking a little sweetened warm tea or diluted fruit juice.If you sense that your are losing your voice,stop talking completely.Save your voice for your speech. You may feel foolish using paper to write notes,but the best thing you can do is to rest your voice.If you need to see a doctor,perhaps you can get some advice from a professional singer. In the meantime,do not even talk in a low voice.What about drinking alcohol to wet your throat?I advice you not to touch alcohol before speaking. The problem with alcohol is that one drink gives you a little confidence.The second drink gives you even more confidence.Finally you will feel all-powerful and you will feel you can do everything,but in fact your brain and your mouth do not work together properly.Save the alcohol until after you finish speaking.Perhaps you want to accept the advice,but you may wonder if you can ever change the habits of a life- time.Of course you can.Goethe,who lived before indoor skating rinks or swimming pools,said,"We learn to skate in the summer and swim in the winter."Take this message to heart and give yourself time to develop your new habits.If you are willing to change,you will soon be able to say that you will never forget these techniques because they became a part of your body.What did Goethe say about skating and swimming?A:He said people could learn to skate when it was hot and swim when it was cold.B:He said people could learn to skate and swim when it was hot.C:He said people could learn to skate and swim when it was cold.D:He said people could learn to skate when it was cold and swim when it was hot.
