10.For some people,music is no fun at all.About 4% of the population is what scientists call"amusic".People who are amusic are born without the ability to enjoy musical notes.Amusic people often cannot tell the differences between two songs.
As a result,songs sound like noise to an amusic.Many amuics compare the sound of music to pieces of metal hitting each other.Life can be hard for amusics.In fact,most people cannot understand what it feel like being amusic.Just going to a restaurant or a shopping center can be uncomfortable or even painful.That is why many amusics have to stay away from places where there is music.However,this can result in social loneliness."I used to hate parties,"says Margaret,a seventy-year-old woman who only recently discovered that she was amusic.By studying people like Margaret,scientists are finally learning how to identify(辨别) this unusual condition.
Scientists say that the brains of amusics are different for those of people who can enjoy music.The difference is complex(复杂的),and it is not connected with poor hearing.Amusics can understand other non-musical sounds well.They also have no problems understanding common speech.Scientists compare amusics to people who just can't see certain colors.
Many amusics are happy when their condition is finally diagnosed(诊断).For years,Margaret felt embarrassed about her music problem.Now she knows that she is not alone.That makes it easier for her to explain."When people invite me to a concert,I just say"No,thanks.I'm amusic.'"says Margret."I just wish I had learned to say that when I was seventeen and not seventy."

32.Amusics are the people whoB.
A.like music                
B.are born unable to enjoy music
C.don't like music                
D.have poor listening
33.Life is hard for amusics mainly becauseD.
A.music seems noise for them.
B.amusics hate parties,restaurants or shopping center.
C.amusics try to stay at places full of music
D.people don't understand amusics
34.In the last paragraph,Margaret expressed her wish thatA.
A.her problem with music had been diagnosed earlier
B.she were seventeen years old rather than seventy
C.her problem could be easily explained
D.she were able to meet other amusics
35.What is the main idea of the passage?A
A.Some people's inability to enjoy music.
B.Musical ability.
C.Amusics'strange behaviors.
D.Identification and treatment of amusic.

7.Why do men die earlier than women?The latest research shows that the reason could be that men's hearts go into rapid decline (衰弱)when they reach middle age.
The largest study of the effects of ageing on the heart has found that women's  longevity  may be linked to the fact that their hearts do not lose their pumping power with age.
"We have found that the power of the male heart falls by 20-25percent between 18and 70years of age,"said the head of the study,David Goldspink of Liverpool John Moores University in the UK.
"Within the heart there are millions of cells(细胞) that enable it to beat.Between the ages of 20and 70,one-third of those cells die and are not replaced in men,"said Goldspink."This is part of the ageing process."
What surprises scientists is that the female heart sees very little loss of these cells.A healthy 70-year-old woman's heart could perform almost as well as a 20-year-old one's.
"This gender(性别) difference might just explain why women live longer than men,"said Goldspink.
They studied more than 250healthy men and women between the ages of 18and 80,focusing on healthy persons to remove the confusing influence of disease.
The team has yet to find why ageing takes a greater toll (造成损失)on the male heart,said Goldspink.
The good news is that men can improve the health of their heart with regular exercise.Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

56.The underlined word"longevity"(in paragraph 2)probably refers toB.
A.health   B.long life   
C.ageing   D.effect
57.The passage mainly talks aboutD.
A.men's heart cells          B.women's ageing process
C.the gender difference       D.hearts and long life
58.According to the passage,the UK scientists have known thatC.
A.women have more cells than men when they are born
B.women can replace the cells that enable the heart to beat
C.the female heart loses few of the cells with age
D.the female heart never loses the pumping power with age
59.If you want to live longer,you shouldC.
A.enable your heart to beat much faster
B.find out the reason for ageing
C.exercise regularly       
D.prevent your cells from being lost
60.We can know from the passage thatB.
A.the reason why ageing causes a greater loss to the male heart has been found out
B.scientists are still doing research into why the male heart loses more of the cells
C.the team has done something to prevent the male from suffering the greater loss of the cells
D.women over 70could lose more cells than those at the age of 20.

4.In Europe,men do not usually wear skirts.But the Scottish national costume for men is a kind of skirt.It is called a kilt.The Scottish lie to be different.They are also proud of their country and its history and they feel that the kilt is part of that history.That's why the men still wear kilts at old-style dances and on national holiday.They believe they are wearing the same clothes that Scottish men always used to wear.
That is what they believe.However,kilts are not really so old.Before 1730,Scottish men wore a long skirt and blanket around their shoulders.These clothes got in the way when the men started to work in factories.So,in 1730 a factory owner changed the blanket into skirt-the kilt.That is how the first kilt was made.
Then,in the late1700s Scottish soldiers in the Br itish Army began to wear kilts.One reason for this was national sentiment.The Scottish soldiers wanted to look different from the English soldiers.The British Army probably had a different reason.A Scottish soldier in a kilt was always easy to find.The Scottish soldiers fought very hard and became famous.The kilt was part that fame,and in the early 1800s men all around Scottish began to wear kilts.
These kilts had colorful stripes going up and down and across.In the 1700s and early 1800s,the color o f the stripes had not special meaning.Men sometimes owned kilts in several different colors.But later the colors became important to the Scottish families.By about 1850,most families had special colors for their kilts.For example,men form the Campbell family had kilts with green,yellow and blue stripes.Scottish people often believe that the colors of the kilts are part of their family history.In fact,each family just chose the colors they liked best.
This is not the story you will hear today if you are in Scotland.Most Scottish people still believe that kilts are as old as Scotland and that the colors are as old as the Scottish families.Sometimes feelings are stronger than facts!
(Note:Answer the questions or complete the statements with NO MORE THAN 10 WORDS)
61.The first kilt was made bya factory owner.
62.By about 1850,Scottish familieshad special colors for their kilts.
63.When do men in Scotland wear kilts now?They wear kilts at dances and on national holiday

11.There is an English saying,"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 really can 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 heart,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 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 effect of pain on the body.In one experiment doctors produced pain in groups of students who listened to different radio programmes.The group that tolerated the pain for the longest time was the group which listened to a funny programme.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,some doctors in the United States 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.
49.The underlined word"diminishes"in the third paragraph means"D".
A.delays        
B.prevents        
C.increases       
D.reduces
50.Why do doctors hold laughter clinics?C
A.Because they want to ear n more money.
B.Because they think they will help the patients recover from illnesses.
C.Because they want to improve their patients'health.
D.Because they want their patients to laugh more.
51.What would be the best title for this passage?D
A.Both laughter and physical exercise are good for health.
B.Laughter clinics can help patients improve their condition.
C.Laughter can reduce the effect of pain.
D.Laughter is the best medicine.
