共用题干Step Back in TimeDo you know that we live a lot longer now than the people who were born before us?One hundred years ago the average woman lived to be 45.But now,she can live until at least 80.One of the main reasons for people living longer is that we know how to look after ourselves better.We know which foods are good for us and what we have to eat to make sure our bodies get all the healthy things they need.We know why we sometimes get ill and what to do to get better again.And we know how important it is to do lots of exercise to keep our hearts beating healthily.But in order that we don't slip back into bad habits,let's have a look at what life was 100 years agoFamilies had between 15 and 20 children,although many babies didn't live long.from lots of diseases , especially rickets (佝偻病)and scurvy(坏血病),which are bot diets.This is because many families were very poor and not able to feed their children well.Really poor families who lived in crowded cities like London and Manchester often slept standing up,bending over a piece of string,because there was no room for them to lie down.People didn't have fridges until the 1920s.They kept fresh food cold by storing it on windowsills(窗台板),blocks of ice,or even burying it in the garden.Some children had to start work at the age of seven or eight to earn money for their pai lived 100 years ago,you might well be selling matchsticks(火柴杆)(a job done by many children)or working with your dad by now.People now enjoy longer lives for unknown reasons.A:RightB:Wrong C:Not mentioned

共用题干Understanding Autism1 Autism(孤独症)is a life-long developmental disability that prevents individuals from proper-ly understanding what they see,hear,and otherwise sense. This results in severe problems of social relationships,communication, and behavior. Individuals with autism have to painstakingly(费力地) learn normal patterns of speech and communication,and appropriate ways to relate to people,ob-jects,and events,in a similar manner to those who have had a stroke.2 The cause of autism is still unknown. Some research suggests a physical problem affecting those parts of the brain that process language and information coming in from the senses. There may be some imbalance of certain chemicals in the brain. Genetic(遗传的)factors may sometimes be in-volved. Autism may indeed result from a combination of several“causes”.3 Most people with mental retardation(智力迟钝)show relatively even skill develop-ment. Individuals with autism,however,typically show uneven skill development,with deficits(欠缺)in certain areas一most frequently in their ability to communicate and relate to others一and distinct skills in other areas.It is important to distinguish autism from mental retardation or ether disorders, since diagnostic(诊断的)confusion may lead to inappropriate and ineffective treatment techniques.4 In general,individuals with autism perform best at jobs which are structured and involve a degree of repetition. Some people who have autism are working as artists,piano tuners,painters,farm workers,office workers,computer operators,dishwashers,assembly line workers,or employees of sheltered workshops or other sheltered work settings.Paragraph 1______A: What Causes Autism?B: How Common Is Autism?C: Does Autism Occur Together With Other Disabilities?D: What Is the Difference Between Autism and Mental Retardation?E: What Is Autism?F: What Kinds of Jobs Can Individuals With Autism Do?

共用题干第三篇Only special plants can survive in the terrible climate of a desert,for these are regions where the annual range of the soil temperature can be over 75℃.Furthermore,during the summer there are few clouds in the sky to protect plants from the sun's ray.Another problem is the fact that there are frequently strong winds which drive small-sharp particles of sand into the plants,tearing and damaging them.The most difficult problem for all forms of plant life,however,is the fact that the entire annual rainfall occurs during a few days or weeks in spring.Grasses and flowers in desert survive from one year to the next by existing through the long, hot,dry season in the form of seeds.These seeds remain inactive unless the right amount of rain falls.If no rain falls,or if insufficient rain falls,they wait until the next year,or even still the next.Another factor that helps these plants to survive is the fact that their life cycles are short.By the time that the water from the spring rains disappears—ust a few weeks after it falls一such plants no longer need any.The perennials(多年生植物)have special features which enable them to survive as plants for several years. Thus,nearly all desert perennials have extensive root systems below ground and a small shoot system above ground.The large root network enables the plant to absorb as much water as possible in a short time.The small shoot system,on the other hand,considerably limits water loss by evaporation(蒸发).Another feature of many desert perennials is that after the rainy season they lose their leaves in preparation for the long,dry season,just as trees in wetter climates lose theirs in preparation for the winter. This reduces their water loss by evaporation during the dry season.Then,in the next rainy season,they come fully alive once more,and grow new branches,leaves and flowers,just as the grasses and flowers in desert do.The last paragraph is mainly about__________.A:the comparison between plants in different areasB:the growth of new leaves in the rainy seasonC:water loss by evaporation in the dry seasonD:the changes in the leaves of the perennials

共用题干Research shows we make up our minds about people through unspoken communication within seven seconds of meeting them. Consciously or unconsciously,we show our true feelings with our eyes,faces,bodies and attitudes,causing a chain of reactions,ranging from comfort to fear.Think about some of your most unforgettable meetings:an introduction to your future spouse,a job interview,an encounter with a stranger. Focus on the first seven seconds.What did you feel and think?How did you"read"the other person?How do you think he read you?You are the message.For 25 years I've worked with thousands who want to be successful.I've helped them make persuasive presentations,answer unfriendly questions,communicate more effectively.The secret has always been you are the message.Others will want to be with you and help you if you use your good qualities.They include:physical appearance,energy,rate of speech, pitch and tone of voice,gestures,expression through the eyes,and the ability to hold the interest of others.Others form an impressiont about you based on these. Think of times when you know you made a good impression.What made you successful?You were committed to what you were talking about and so absorbed in the moment you lost all self-con-sciousness.Many books advise you to stride into a room and impress others with your qualities.They instruct you to greet them with"power handshakes"and tell you to fix your eyes on the other person. If you follow all this advice,you'll drive everyone crazy一including yourself.The trick is to be consistent at your best.The most effective people never change from one situation to another. They're the same whether they're having a conversation,addressing their garden club or being interviewed for a job.They communicate with their whole being;the tones of their voices and their gestures match their words.The first seven seconds of meeting can help us read the other person.A:Right B:Wrong C:Not mentioned

共用题干Using HIV Virus to Cure CancerScientists are planning to use human immuno deficiency(免疫缺陷)virus(HIV) , one of mankind's most feared viruses,as a carrier of genes which can fight cancer and a range of diseases that cannot be cured.The experts say HIV has an almost perfect ability to avoid the body's immune(免疫的)defenses, making it ideal for carrying replacement genes into patients'bodies,according to the Observer.A team at the California-based Salk Institute,one of the world's leading research centers on biological sciences,has created a special new breed of HIV and has started negotiations with the U.S.Food and Drug Administration(FDA)to begin clinical gene therapy(治疗)trials this year.The first trials are expected to involve patients suffering from cancers that cannot be cured by surgery although project leader Professor Inder Verma said the HIV technique would have“far wider applications”.The plan remains very likely to cause controversy since it involves making use of a viruswhich has caused more than 22 million deaths around the world in the past two decades.Verma said that the idea of using HIV for a beneficial purpose was“shocking”but the fierce nature of HIV had disappeared by having all six of the potentially deadly genes removed.Illnesses such as various cancers are caused when a gene in a patient's body fails to work properly.In the past two years, breakthroughs in genetics(遗传学)have led gene therapy sci-entists to try and replace the genes that do not function normally.Unfortunately,the body's immune defenses have been known to attack the modified genes and make them lose their effects before they can start their task and progress in the field has been held up by the lack of a suitable carrier.The HIV virus has the ability to escape from,and then destroy,the immune defense cells designed to protect our bodies and this makes it attractive to scientists as a way of secretly conveying replacement genes into patients'bodies.FDA has approved the plan of using HIV to cure cancer in humans.A:RightB:WrongC:Not mentioned

共用题干Every Dog Has Its SayKimiko Fukuda,a Japanese girl,always wondered what her dog was trying to say.Whenever she put on makeup,it would pull at her sleeve._______(46)When the dog barks,she glances at a small electronic gadget(装置).The following“ human” translation appears on its screen:“ Please take me with you .I realized that's how he was feeling.”said Fukuda.The gadget is called Bowlingual,and it translates dog harks into feelings .People laughed when the Japanese toymaker Takara Company made the world's first dog-human translation ma- chine in 2002 .But 300,000 Japanese dog owners bought it.________(47)“Nobody else had thought about it,”said Masahiko Kajita,who works for Takara. We spend so much time training dogs to understand our orders;what would it be like if we could understand dogs?Bowlingual has two parts.________(48)The translation is done in the gadget using a data- base(资料库)containing every kind of bark. Based on animal behaviour research,these noises are divided into six categories:happiness,sadness,frustration,anger,declaration and desire.________ (49)In this way,the database scientifically matches a bark to an emotion,which is then translated into one of 200 phrases.When a visitor went to Fukuda's house recently,the dog barked a loud“bow wow”.This translated as“Don't come this way”.________(50)The product will be available in US pet stores this summer for about US$120 .It tail store up to 100 barks,even recording the dog's emotions when the owner is away.________(50)A: A wireless microphone is attached to the dog's collar,which sends information to the gadget held by the owner.B: Nobody really knows how a dog feels.C: It was followed by“I'm stronger than you”as the dog growled(嗥叫)and sniffed(嗅)at the visitor.D: More customers are expected when the English version is launched this summer.E: Now,the Japanese girl thinks she knows.F: Each one of these emotions is then linked to a phrase like“Let's play”.“Look at me”or “Spend more time with me”.

共用题干第三篇Exercise Can Replace Insulin for Elderly DiabeticsMost old people with so-called type Ⅱ diabetes could stop taking insulin if they would do brisk exercise for 30 minutes just three times a week,according to new medical research results reported in the Copenhagen newspaper Berlingske Tidende on Monday.Results from tests conducted on diabetics at the Copenhagen Central Hospital Rigshospitalet's Center for Muscle Research showed that physical exercise can boost the body's ability to utilise insulin by 30 percent,the newspaper reported.This is equal to the effect most elderly diabetics get from their insulin medication today,it said.Researchers had a group of non-diabetic men and a group of men with type Ⅱ,all more than 60 years of age,exercise on bicycles six times a week for three months.After the three months the doctors measured how much sugar the test subjects'muscles could utilise as a measure for how well their insulin worked.Associate Professor Dr. Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had just as high insulin utilisation as the healthy non-exercising persons."This means that the insulin works just as well for both groups.Physical exercise cannot cure people of diabetes,but it can eliminate almost all their symptoms.At the same time it can put off the point at which they have to begin taking insulin or perhaps completely avoid insulin treatment,"Dela was quoted as saying.Insulin is a hormone produced by the pancreas,controlling sugar in the body and used against diabetes.Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to work up a sweat,but that the activity has to be maintained since it wears off after five days without sufficient exercise.Most diabetics realise that they have to watch their diet while remaining unaware of the importance of exercise,Dela added.Physical exercise may increase the body ability to utilise insulin by___________.A:70 percentB:30 percentC:60 percentD:only a few percent

共用题干第三篇Sprained(扭伤)AnkleOne of the most common injuries teenagers and adults experience is a sprained ankle.A sprain occurs when the ligaments(韧带)of a joint are twisted(扭伤)and possibly torn. Ligaments are bands of fibers that hold the bones of a joint in position.A sprain can occur from a sudden twisting at the joint,or a stretching or tearing of the fibers of the ligaments. The injured area usually swells(肿胀)and becomes black and blue. Stepping off the sidewalk at the wrong angle or having one foot land in a hole while walking or running can leave you rolling on the ground in pain with an ankle on fire!If you cannot walk without experiencing intense pain,you must seek medical help.If the pain is manageable,and you can walk,here are three words to help you remember how to treat yourself:● Elevate(抬高)●Cool● Bandage(打绷带)As soon as there is injury to that ligament,there will be a certain amount of bleeding under the skin. Once the blood poois around the damaged blood vessels,swelling occurs.The pressure from the swelling results in additional stress and tenderness to the region.In order to reduce the degree of swelling,lie down as soon as possible and keep the ankle elevated so that it is actually higher than your heart. Next,to reduce blood distribution and keep bleeding(流血)to a minimum , apply a cold pack. After 20 minutes , take thepack off,wait half an hour,and then reapply.This can be done several times a day for a total of three days.Never leave a cold pack on for more than 20 minutes at a time.Reducing the temperature in that area for an extended period of time signals the body to increase blood flow to raise the body temperature!Therefore, one accidentally triggers(引起)more blood distribution to the affected area by leaving a cold pack on for too long!Finally,bandage the ankle.Be careful not to wind it too tightly;doing so can restrict blood flow and cause harm to the entire foot. The black-and-blue symptom of a sprain is due to_________.A:bleeding under the skinB:a tight bandageC:applying a cold packD:pressing one's ankle
