1.There is an English saying that"Laughter is the best medicine."Until recently,few people took the saying seriously.Now however,doctors have begun to look into laughter and the effects it has on the human body.They have found that laughter can really improve people's health.
Tests were carried out to study the effects of laughter on the body.People watched funny films while doctors checked their hearts,blood pressure,breathing and muscles.It was found that laughter has similar effects to physical exercise.It increases blood pressure,makes the heart beat quicker and makes people breathe deeper; it also works on several groups of muscles in the face,the stomach,and even the feet.If laughter exercises the body,it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effects of pain on the body.In one experiment doctors produced pain in groups of students who listened to different radio programs.The group that tolerated(忍耐)the pain for the longest time was the group which listened to a funny program.The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain which diminishes both stress and pain.
As a result of these discoveries,some doctors in the United States now hold laughter clinics,in which they help to improve their patients'condition by encouraging them to laugh.They have found that even if their patients do not really feel like laughing,making them smile is enough to produce beneficial effects similar to those caused by laughter.
32.What do we learn from the tests mentioned in paragraph 2?C
A.Laughter has totally different effects when compared with physical exercise.
B.Laughter can help to decrease blood pressure.
C.Tests'purposes were to study the influence of laughter on the body.
D.Laughter makes no difference to our feet.
33.The underlined word in paragraph 3can be replaced byD.
A.increase      
B.raise      
C.a(chǎn)dd       
D.reduce
34.According to the passage,the following statements are true exceptC..
A.Laughter is good for health.
B.Laughter helps to reduce pain.
C.Laughter can make you become old.
D.Laughter has good effects on patients.
35.The best title for this passage may beD..
A.Both laughter and physical exercise are good for health
B.Laughter clinics help patients improve their condition
C.Laughter can reduce the effects of pain
D.Laughter is the best medicine.

12.Car companies are developing vehicles that will plug into electric sockets,just like many laptops,digital cameras,cell phones and Mp4do.Called"plug-in vehicles",these cars will get most of their power from electricity.Their drivers won't have to stop at gas stations as often as usual.
The technology is more than just cool.In our car-filled world,plug-in vehicles could reduce the amount of gas we use,which keeps rising in cost now and then.Besides,driving around in these vehicles may even help the environment.Gas-burning cars produce a lot of greenhouse gas,which causes globe warming.
The first company-produced plug-in vehicles could hit the roads by 2020.But engineers still have a lot of work to do to make the technology practical and inexpensive.
Batteries(電池) are the biggest challenge.In the plug-in-vehicle world,Li-ion(鋰離子)batteries are getting the most attention.These batteries can store a large amount of energy in a small package,and they last a longer time between charges.Li-ion batteries can fit laptops,cell phones,heart instruments and other similar pocket ones.
But because cars are so big and heavy,it would still require a suitcase-sized Li-ion batteries to power about 12km of driving.What's more,the batteries are much expensive.
"A car filled with batteries could go a long distance,"says Ted Bohn,an electrical engineer in Chicago."But it couldn't pull any people.a(chǎn)nd it would cost﹩100,000."
So researchers need to work out how to make batteries smaller and cheaper,among other questions.
"The answers don't exist yet,"Bohn says,"As a kid,I thought someone someplace knows the answer to everything.All of these questions haven't been decided.That's what engineering is about-making a guess,running tests and getting fine results."

20.The passage mainly talks aboutD  of a new car
A.the developing    
B.the speed    
C.the appearance 
D.the batteries.
21.Which is true according to the passage?B
A.The"plug-in vehicles"will use electricity completely as driving power.
B.The new technology will help protect our environment.
C.The technology of using electricity as driving is quite practical now.
D.The biggest challenge of the new technology is that it will cost us more energy.
22.How does Bohn feel about the future of the technology according to the last paragraph?A
A.Confident    
B.Puzzled.    
C.Worried. 
D.Disappointed.
23.According to the passage,the new technology is facing the following problems except thatC.
A.the new technology cannot come into use at present
B.the cost of the new technology is quite high
C.the government won't support the technology
D. the size of the batteries is too big at present.

9.If you think a high-factor sunscreen (防曬霜) keeps you safe from harmful rays,you may be wrong.Research in this week's Nature shows that while factor 50reduces the number of melanomas (黒瘤) and delays their occurrence,it can't prevent them.Melanomas are the most aggressive skin cancers.You have a higher risk if you have red or blond hair,fair skin,blue or green eyes,or sunburn easily,or if a close relative has had one.Melanomas are more common if you have periodic intense exposure to the sun.Other skin cancers are increasingly likely with long-term exposure.
There is continuing debate as to how effective sunscreen is in reducing melanomas---the evidence is weaker than it is for preventing other types of skin cancer.A 2011Australian study of 1,621people found that people randomly selected to apply sunscreen daily had half the rate of melanomas of people who used cream as needed.A second study,comparing 1,167people with melanomas to 1,101who didn't have the cancer,found that using sunscreen routinely,alongside other protection such as hats,long sleeves or staying in the shade,did give some protection.This study said other forms of sun protection---not sunscreen---seemed most beneficial.The study relied on people remembering what they had done over each decade of their lives,so it's not entirely reliable.But it seems reasonable to think sunscreen gives people a false sense of security in the sun.
Many people also don't use sunscreen properly---applying insufficient amounts,failing to reapply after a couple of hours and staying in the sun too long.It is sunburn that is most worrying---recent research shows five episodes of sunburn in the teenage years increases the risk of all skin cancers.
The good news is that a combination of sunscreen and covering up can reduce melanoma rates,as shown by Australian figures from their slip-slop-slap campaign.So if there is a heat wave this summer,it would be best for us,too,to slip on a shirt,slop on (抹上) sunscreen and slap on a hat.
12.What does the research in Nature say about a high-factor sunscreen?A
A.It is ineffective in preventing melanomas.
B.It is ineffective in case of intense sunlight.
C.It is ineffective with long-term exposure.
D.It is ineffective for people with fair skin.
13.What do we learn from the 2011Australian study of 1,621people?D
A.Sunscreen should be applied alongside other protection measures.
B.High-risk people benefit the most from the application of sunscreen.
C.Irregular application of sunscreen does women more harm than good.
D.Daily application of sunscreen helps reduce the incidence of melanomas.
14.What does the author say about the second Australian study?C
A.It misleads people to rely on sunscreen for protection.
B.It helps people to select the most effective sunscreen.
C.It is not based on direct observation of the subjects.
D.It confirms the results of the first Australian study.
15.What does the author suggest to reduce melanoma rates?A
A.Using both covering up and sunscreen.
B.Staying in the shade whenever possible.
C.Using covering up instead of sunscreen.
D.Applying the right amount of sunscreen.

16.Our love of music and appreciation of musical harmony (和聲) is learnt and not based on natural ability,a new study by University of Melbourne researchers has found.The researchers said previous theories about how we appreciate music were based on the physical functions of sound,the ear itself and a born ability to hear harmony.
The study shows that musical harmony can be learnt,and it is a matter of training the brain to hear the sounds.So if you thought that the music of some foreign culture (or Jazz) sounded like the crying of cats,it's simply because you haven't learnt to listen by their rules.
The researchers used 66volunteers with a range of (一系列的) musical training and tested their ability to hear combinations (組合) of notes (音符) to determine if they found the combinations familiar or pleasing.They found that people needed to be familiar with combinations of notes.If they couldn't recognize the notes,they found the notes  dissonant.This finding put an end to centuries of theories claiming (聲稱) that physical functions of the ear determine what we find attractive.
The study found that trained musicians were much more sensitive (敏感的) to unpleasant notes than non-musicians.When they couldn't find the note,the musicians reported that the sounds were unpleasant,while non-musicians were much less sensitive.This shows the importance of training or nurturing (培養(yǎng)) the brain to like particular sound of combinations of notes,like those found in jazz or rock.
Depending on their training,a strange chord (和弦) sound was pleasant to some musicians,but very unpleasant to others.This showed us that even the ability to hear a musical note is learnt.
To confirm (證實(shí)) this finding,they trained 19non-musicians to find the notes of a random (隨機(jī)的) selection of western chords.Not only did the participants'ability to hear notes improve rapidly; the chords they had learnt sounded more pleasant-regardless of (不論) how the chords were played.
The question of why some combinations of musical notes are heard as pleasant or unpleasant has long been debated."We have shown in this study that for music,beauty is in the brain of the beholder(觀看者),"a researcher said.
27.According to the passage,why do people sometimes find foreign music quite unpleasant?C
A.Because they don't like the person playing the music.
B.Because they have no talent for music at all.
C.Because they have no idea about how to listen.
D.Because they hear music too often.
28.The underlined word"dissonant"in Paragraph 3probably meansB.
A.informal     
B.unpleasant   
C.inspiring   
D.unfamiliar
29.Although non-musicians were less sensitive to music,they can stillC.
A.find the beauty of chords without training
B.enjoy the beauty of music when played by musicians
C.be trained to like particular music
D.make friends with real musicians
30.What is the best title for the passage?D
A.Improve Your Brain By Listening to Music
B.You Can Be a Musician Without Being Trained
C.Music Can't be Taught
D.Love of Music Is Not Natural But Nurture.

6.Most of us don't remember our first two or three years of life.But our earliest experiences may stick with us for years and continue to influence us well into adulthood.
A study,published in Child Development,found that the type of emotional support that a child receives during the first three and a half years has an effect on education,social life and romantic relationships even 20or 30years later.
Babies raised in supportive and caring home environments tended to do better on tests later on,and they were more likely to get higher degrees as adults.They were also more likely to get along with their classmates and feel satisfied in their romantic relationships.
"It seems like,at least in these early years,the parents'role is to communicate with the children and let them know,‘I'm here for you when you're upset,when you need me.And when you don't need me,I'm your cheerleader,'"says Lee Raby,a psychologist and researcher at the University of Delaware who led the study.
Raby used data collected from 243people who participated in the Minnesota Longitudinal Study of Risk.All the participants were followed from birth until they turned 32."Researchers went into these kids'home at times.Other times,they brought the children and their parents to the university and observed how they communicated with each other,"says Raby.
Of course,parental behavior in the early years is just one of many influences,and it's not necessarily causing the benefits seen in the study.While summarizing the results,the researchers accounted for the participants'social status and the environment in which they grew up.
Finally,they found that about 10percent of someone's academic achievement was connected with the quality of their home life at three.Later experiences,genetic factors and even luck explain the other 90percent.
8.The text is especially helpful for those who care aboutB.
A.individual experiences             
B.child development
C.human relations                   
D.educational background
9.What can we learn about people who have had bad childhood experiences from the text?D
A.They don't remember their younger days at all when growing up.
B.They long for emotional support to do better at school.
C.They can't recover from separating from their parents.
D.They are still affected by their earliest experiences even decades later.
10.Researchers collected data mainly byC.
A.photographing the participants'daily lives
B.communicating with the participants'parents
C.observing the participants'behavior
D.summarizing the participants'position.

13.We can stay young forever.That is the message Dr.Shen Ziyin wants to give the world.And the Chinese doctor claims(聲稱) that he has found an answer to the problems of aging.
His solution(解決辦法) is a herbal medicine to slow the process of aging.
Dr.Shen Ziyin has been trained in Western medicine.At the same time he studied traditional Chinese medicine.And,he has been working for the past forty years to put together the best of both and find a cure for aging.He has taken a hint(線索) from the ancient Chinese medicine system called"shen".
According to Shen,it is the kidney(腎) which adjusts the functioning of the body as well as its aging process.It is responsible for the level of activity that the human bodies go through.Studies conducted by Dr.Shen show that herbal medicine based on the shen system slow the aging process,says a report in The Telegraph newspaper.
We notice that when people grow old,they have reduced strength,loss of hair,backache,weakness in general,and wrinkles,among others.This happens because when people grow old,their bodies produce T-cells.These T-cells contain a particular substance called Fas.Fas makes the cells in the body destruct themselves.
So the only way to slow down aging is to slow the production of T-cells in the body.This can happen if people eat low calorie food.Then the body is not active enough to produce extra T-cells.But,is going hungry all the time a good price to pay for staying young?
This is where Dr.Shen's herbal medicine comes in.But how effective it will be,only time can tell.
28.How did Dr.Shen find the solution to the problem of aging?D
A.By studying Western medicine.
B.By learning traditional Chinese medicine.
C.By doing research on both Western and Chinese people.
D.By combining both Western and Chinese medicine.
29.What plays the most important role in keeping people young according to Shen?A
A.People's good kidney.
B.Medical treatment.
C.Level of people's activity.
D.Positive life attitude.
30.The reason why people become old is thatC.
A.their bodies are unable to fight diseases
B.they have reduced strength,loss of hair
C.their bodies produce T-cells
D.they become weaker and weaker
31.We can probably learn from the passage thatB.
A.people should try to quicken the production of T-cells in the body
B.it remains unknown how effective Dr.Shen's herbal medicine is
C.the more Chinese herbal medicine people drink,the better for health
D.producing more low calorie food allows people to keep young.

16.Many people say dolphins are very intelligent.They seem to be able to think,understand,and learn things quickly.But are they smart like humans or more than cats or dogs?Dolphins use their brains differently from people.But scientists say dolphin intelligence and human intelligence are similar in some ways.How?
l  Fact 1:Talk to me
    Like humans,every dolphin has its own"name".The name is a special whistle.Each dolphin chooses a specific whistle for itself,usually by its first birthday.Actually,scientists think dolphins,like people,"talk"to each other about a lot of things,such as their age,their feelings,or finding food.And,like humans,dolphins use a system of sounds and body language to communicate.But understanding their conversations is not easy for humans.No one speaks"dolphin"yet,but some scientists are trying to learn.
l  Fact 2:Let's play
    Dolphins are also social animals.They live in groups,and they often join others from different groups to play games and have fun--just like people.In fact,playing together is something only intelligent animals do.
l  Fact 3:Fishermen's helper
    Dolphins and humans are similar in another way:both make plans to get something they want.In the seas of southern Brazil,for example,dolphins use an interesting strategy to get food.When fish are near a boat,dolphins show signs to the fishermen to put their nets in the water.Using this method,the men can catch a lot of fish.What is the advantage for the dolphins in doing so?They get to eat some of the fish.
