6.We have seen that humor and laughter positively influence our body in many ways,but little research has been done on whether a better sense of humor actually helps keep you from getting sick.However,since people with a better sense of humor have higher IgA levels,and since research has shown that those with higher levels of salivary(唾液的) IgA are less likely to get colds or be infected with Streptococcus,humor should reduce the frequency of colds.
The only study to directly examine this question found that the impact of one's sense of humor upon colds depends on the kind of sense of humor you have.It was only individuals whose sense of humor took the form of seeking out and appreciating humor who had fewer and less severe colds/flu than their low humor counterparts.Surprisingly,those whose sense of humor took the form of initiating humor more often did not have fewer or less severe colds/flu.The researchers argued that being a person who likes to tell jokes or otherwise initiate humor takes them into more frequent contact with other people,which serves to expose them to infectious agents more often,robbing them of the advantage that a more active sense of humor otherwise offers.Obviously,more research is required to clear up this confusing picture.
The importance of active use of one's sense of humor in producing humor's health benefits was confirmed in another study in an unusual way.It found that among a group of mothers with newborn infants,those who actively used humor to cope with the stress in their lives had fewer upper respiratory infections and their infants also had fewer infections.This seemed to be because these mothers had higher levels of immunoglobulin A (免疫球蛋白A) in their breast milk.
Among adults,if we look at bodily symptoms alone,independent of any diagnosed illness,there is some evidence that individuals who have more negative reactions to humor report more bodily symptoms and complaints.Students complaining of cardiovascular(心脏血管的) symptoms and gastroenterological (肠胃病的) symptoms also have been shown to have this more negative reaction to humor.

63.What does the passage mainly talk about?A
A.People with a good sense of humor get sick less often.
B.Humor can reduce the frequency of colds/flu.
C.Any form of humor can prevent people from getting sick.
D.Humor can treat illness.
64.According to the passage,IgA isB.
A.a medicine    B.enzyme     C.factor     D.measure
65.Why do newborn infants whose mothers use humor to deal with stress have fewer infections?C
A.Because they don't often get upper respiratory infections.
B.Because they are stronger since they were born.
C.Possibly because of the higher levels of immunoglobulin A in their breast milk.
D.Because their mothers take better care of them.
66.Students with some bad bodily symptoms showB towards humor.
A.a positive attitude           B.a negative attitude
C.a neutral attitude            D.an unclear attitude.

17.One day,Mr.Arnold was teaching a lesson,and things were going as normally as ever.He was explaining the story of human being to his pupils.He told them that,in the beginning,men were nomads (游牧); they never stayed in the same place for very long.Instead,they would travel about,here and there,in search of food,wherever it was to be found.And when the food ran out,they would move off somewhere else.
He taught them about the invention of farming and keeping animals.This was an important discovery,because by learning to cultivate (耕作) the land,and care for animals,mankind would always have food steadily.It also meant that people could reain living in one place,and this made it easier to set about tasks that would take a long while to finish,like building towns,cities,and all that were in them.All the children were listening attracted by this story,until Lucy jumped up:
"And if that was so important and improved everything so much,why are we nomads all over again,Mr.Arnold?"Mr.Arnold didn't know what to say.Lucy was a very clever girl.He knew that she lived with her parents in a house,so she must know that her family were not nomads; so what did she mean?
"We have all become nomads again,"continued Lucy,"The other day,outside the city,they were cutting the forest down.A while ago a fisherman told me how they fish.It's the same with everyone:when there's no more forest left the foresters go elsewhere,and when the fish run out the fishermen move on.That's what the nomads did,isn't it?
The teacher nodded,thoughtfully.Really,Lucy was right.Mankind had turned into nomads.Instead of looking after the land in a way that we could be sure it would keep supplying our needs,we kept developing it until the land was bare.And then off we would go to the next place!The class spent the rest o the afternoon talking about what they could do to show how to be more civilized (文明的).
The next day everyone attended class wearing a green T-shirt,with a message that said"am not a nomad!"
And,from then on,they set about showing that indeed they were not.Every time they knew they needed someting,they made sure that they would get it using care and control.If they needed wood or paper,they would make sure that they got the recycled kind.They ordered their fish from fish farms,making sure that the fish they received were not too young and too small.They only used animals that were well cared for,and brought up on farm.
And so,from their little town,those children managed to give up being nomads again,just as prehistoric men had done,so many thousands of years ago.

A.To experience different lifestyles.
B.To go sightseeing in different places.
C.To find what they could to feed themselves.
D.To do more exercise to build themselves up.

A.mankind has been progressing mainly through traveling about
B.it's unwise for mankind to use the land in an uncontrolled way
C.it's quite good for students to learn more about the history of mankind
D.teachers should encourage students to voice their own opinions brvely.
14.If English means endless new words,difficult grammar and sometimes strange pronunciation,you are wrong.Haven't you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university,learning a second language can lead to an increase in your brain power.Researchers found that learning other lan guages changes grey matter.This is the area of the brain which processes information.It is similar to the way that exercise builds muscles.
The study also found the effect is greater when the younger people learn a second language.A team led by Dr.Andrea Mechelli,from University College London,took a group of Britons who only spoke English.They were compared with a group of"early bilinguals"who had learnt a second language before the age of five,as well as a number of later learners.
Scans showed that grey matter density (密度) in the brain was greater in bilinguals than in people without a second language.But the longer a person waited before mastering a new language,the smaller the difference.
"Our findings suggest that the structure of the brain is changed by the experience of learning a second language,"said the scientists.It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales,has researched the link between bilingualism and maths skills."Having two languages gives you two windows on the world and makes the brain more flexible (灵活的),"he said."You are actually going beyond language and have a better understanding of different ideas."
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and thirty-four.Reading,writing,and comprehension were all tested.The results showed that the younger they started to learn,the better."Studying a language means you get an entrance to another world,"explained the scientists.
32.The main subject talked about in this passage isC.
A.science on learning a second language    
B.man's ability of learning a second language
C.that language can help brain power       
D.language learning and maths study
33.The underlined word"bilingual"probably meansC.
A.a researcher on language learning        
B.a second language learner
C.a person who can speak two languages    
D.an active language learner
34.We may know from the scientific findings thatA.
A.the earlier you start to learn a second language,the higher the grey matter density is
B.there is no difference between a later second language learner and one who doesn't know a second language
C.the experience of learning a second language has bad effect on people's brain
D.the ability of learning a second language is changing all the time
35.In the last two paragraphs,the author wants to tell us thatB.
A.learning a second language is the same as studying maths
B.early learning of a second language helps you a great deal in studying other subjects
C.Italian is the best choice for you as a second language
D.you'd better choose the ages between 2 and 34 to learn a second language.
11.The private automobile (汽车) has long played an important role in the United States.In fact,it has become a necessary and important part of the American way of life.By giving workers rapid transportation,the automobile has freed them from having to live near their place of work.This has encouraged the growth of the cities,but it has also led to traffic problems.
For farm families the automobile is very helpful.It has made it possible for them to travel to town very often for business and for pleasure,and also to transport their children to distant schools.
Family life has been affected in various ways.The car helps to keep families together when it is used for picnics,outing,and other shared experiences.However,when teenage children have the use of the car,their parents can't keep any eye on them.There is a great danger if the driver has been drinking alcohol or taking drugs,or showing off by speeding or breaking down traffic laws.Mothers of victims of such accidents have formed an organization called MADD (Mothers Against Drunk Driving).These women want to prevent further tragedies.They have worked to encourage the government to limit the youngest drinking age.Students have formed a similar organization,SADD (Students Against Drunk Driving) and are spreading the same message among their friends.
For many Americans the automobile is a necessity (必需品).But for some,it is also a mark of social position and for young people,a sign of becoming an adult.Altogether,cars mean very much to Americans.

32.Which of the following is NOT mentioned in the passage?D
A.Cars have encouraged the growth of the cities.
B.Cars can bring families together when they go for picnics.
C.Cars have enabled people to live far from their place of work.
D.Cars help city families to transport their children to faraway schools.
33.What has been done to deal with the problem of drunk driving?C
A.Parents have paid more attention to their children.
B.University students have asked the government to solve the problem.
C.Some organizations have been set up against drunk driving.
D.Mothers have tried to persuade their children not to drink alcohol.
34.We can infer from the passage thatB in America.
A.it will be more difficult for people to get new cars
B.cars will still be popular though they have caused many problems
C.parents will not allow their children to have their own cars
D.the government will encourage people to use public transportation
35.In the United States,people think the automobile means much to themA.
A.though different people have different ideas on the use of the automobile
B.because everybody has a car
C.because for people,except the young,it is a necessity as well as a convenience
D.though children are not allowed to use cars by their parents.
15.Measuring up to 10.5 feet in length,the western green mamba (曼巴蛇) is the second longest snake in Africa,with the black mamba being the first.It is also the most agile (敏捷的) snake in the mamba family.Their color is changeable,which helps them join their environment.Another distinctive feature of the snake is its long tail with a sharp point.
The western green mamba lives in rain forests.Being an arboreal species,these snakes spend most of their time moving among the tree tops.However,they usually leave their trees to pursue a potential meal on the ground.The western green mamba is mostly active at day,but can also be seen hunting at night.
The diet of a western green mamba consists of birds and a variety of small mammals such as squirrels,mice and even bats.These snakes will approach their targets with the help of their natural skin color.When they are close enough,they will bite their victims and inject them with venom(毒液) quickly.Once the target has died,the weatern green mamba will swallow its meal whole.If faced with danger,these snakes will try to run away.If they are cornered,however,they will become extremely aggressive and strike with their sharp teeth repeatedly.The female weatern green mamba is the one who lays eggs.She will lay eggs anywhere.The young snakes are completely independent.The mother and father play no part in raising the baby snakes.The babies are born with everything they need to survive in the wilderness.They will have almost no natural predators(捕食者)to worry about when they reach adulthood.
29.In order to avoid being found,the western green mambaD.
A.spends most of the day sleeping
B.rarely comes out to hunt for food
C.tends to stay on trees most of the day
D.hides itself well with the help of its skin color
30.What does the underlined word"arboreal"in the second paragraph probably mean?C
A.Mainly feedig on meat.
B.Mainly feeding on plants
C.Living on trees most of the time           
D.Living in the grass most of the time
31.When is the western green mamba most aggressive?D
A.when it has to protect its eggs
B.When it is searching for food.
C.When it approaches its target
D.When it gets no way to escape
32.What can we learn from the text?D
A.The western green mamba can be found all over Africa.
