17．When I was small and my grandmother died.I couldn't understand why I had no tears．But that night ——青夏教育精英家教网—

17．When I was small and my grandmother died，I couldn't understand why I had no tears．But that night when my dad tried to cheer me up，my laugh turned into crying．
So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain．Just as laughing has many health advantages，scientists are discovering that so，too，does crying．
Whatever it takes for us to reduce pressure is important to our emotional （情感的） health，and crying seems to work well．One study found that 85percent of women and 73percent of men report feeling better after crying．
Besides，tears attract help from other people．Researchers agree that when we cry，people around us become kinder and friendly and they are more ready to provide support and comfort．Tears also enable us to understand our emotions better； sometimes we don't even know we're very sad until we cry．We learn about our emotions through crying，and then we can deal with them．
Just as crying can be healthy，not crying---holding back tears of anger，pain or suffering---can be bad for physical health，Studies have shown that too much control of emotions can lead to high blood pressure，heart problems and some other illnesses．If you have a health problem，doctors will certainly not ask you to cry．But when you feel like crying，don't fight it．It's a natural---and healthy---emotional response （反应）．

16．Dear Sir，
I have to travel every day from Souk Road to the airport．Two buses travel along their route：the number 49and number 16．But by the time the number 16bus reaches Souk Road it is always full，so I can't get on it．I have to wait for the number 49，because sometimes there are empty seats on it．
The timetable says that there are buses from Souk Road to the airport every ten minutes．If this is so，why do I have to wait half an hour for a bus nearly every day？
The regulations （规章） say that if there are empty seats on a bus，the bus must stop at every stop where people are waiting．Why do the half-empty buses go straight past me when I am standing at the bus stop？
The regulations say that no bus may carry more than 40seated passengers and 20standing passengers．Yesterday I was the first to get off the bus when it reached the airport．I counted the other passengers as they got off．There were 129of them．
It is clear that our bus companies break the regulations and think little of their passengers．Can nothing be done to make your service better？
Yours，
Tired passenger

15．The twenty-four horses dash around a racetrack．The thunder of their hooves （蹄） rings in the riders'ears，nearly drowning out the cheering of the crowd．After three or four minutes of suspense，one horse crosses the finish line first，winning the Melbourne Cup and earning a place in history．
The horses that compete in the Melbourne Cup-one of the world's most famous horseraces-were fated to race．Bred for speed，these horses are the few that were singled out as having potential to become champions．
Preparing a racehorse to compete requires a team．A horse's owner manages the team and decides which races to enter．A trainer determines the racehorse's diet and exercise．Regular exercise makes a horse less likely to be injured，but overtraining tires the horse．A groomer （动物美容师） cares for the racehorse and reports any problems he discovers to the trainer．And of course，no horserace could be run without a rider．These riders train for long hours and travel constantly from one race to another．They need to make a strategy，adapt to changing conditions and communicate with their horse to guide it to victory．
Australia's most famous horserace，the Melbourne Cup，is 3，200meters of pure excitement．Each year 300or 400horses are nominated （提名），but only 24can run．The competitors are chosen based on a number of factors，but winners of certain races qualify automatically．
Each racehorse receives a handicap-a certain weight it must carry to give each horse an equal chance of winning-two months before the race．Originally，horses that seemed likely to win were assigned larger handicaps．But the rules have changed，reducing the handicap for previous winners．
The first Melbourne Cup in 1861drew a crowd of 4，000spectators，and the race's popularity has grown since then．Held on the first Tuesday of November，the cup has become a four-day festival with fine food and entertainment．
The Melbourne Cup began during a gold rush as a form of entertainment for the rich．Today it still attracts society's upper class．They come dressed in their finest to enjoy the event in comfort．
But anyway it's all about the race-the effort of horses and riders，the suspense and the thrill of victory．

66．What can be learned about the horses in the Melbourne Cup？B
A．They are all winners of a certain race．
B．They are raised and trained by joint effort．
C．They are chosen from ordinary horses．
D．Their fates are determined by their trainers．

D．they will be more adaptable to the race
68．It can be learned from the passage thatB．
A．the spectators of the Melbourne Cup must dress well
B．the Melbourne Cup was intended for wealthy people
C．the winner of the Melbourne Cup can earn a large fortune
D．the Melbourne Cup is the best-known horserace worldwide
69．The passage can most probably be found inA．

B．a business newspaper
C．an academic paper
D．a health magazine．

14．The elevator of the future may be just over the horizon thanks to German company    ThyssenKrupp．The firm has invented a cable-free elevator（called MULTI）that can go up and    down like traditional lifts but the magnetic motors allow it to go side-to-side too．The designers predict that this technology could increase the carrying capacity of existing architecture by as much as 50%．Plus it looks really neat．
ThyssenKrupp plans to use light-weight materials to build its elevator ears of the future and the lack of a cable winch（钢缆绞车）will reduce weight as well．The ears wouldn't just move up and down as they do now but would instead go in a circle that allows more cars to slip in fight behind the next．The result is that you might only have to wait 10 seconds for the next one to arrive rather than wait for the one you just missed to come back down．
The technology backing ThyssenKrupp's MULTI elevator is very similar to magnetic    levitation（磁悬浮）systems used in high-speed trains．Each car has two magnetic motors-one    for vertical movement and another for horizontal．This system can also deliver power to the car's internal lighting and electronics without using wires．
A traditional cable driven elevator has mechanical components that can hold the car in place in the event of a power-off．ThyssenKrupp didn't go into detail about safety measures in its announcement but it's safe to say the magnetic levitation elevator will have some sort of system to hold it in place if the lights go out．ThyssenKrupp is working on a test tower that will be used to develop the MULTI into a rear elevator technology．This should be up and running by 2016 but it will probably take at least a few more years before you get to climb inside a magnetic elevator car．
32．What does the underlined phrase"over the horizon"mean？B

13．Helsinki is offering young people the chance to rent a cheap apartment in an old people's home，if they agree to spend time socialising with the elderly residents．
The city council is seeking applications from renters under the age of 25 who will commit to spending between three and five hours each week with their older neighbours，at a care home in the eastern Laajasalo district．In exchange，they'll get a studio flat measuring 23 square meters with a private kitchen，bathroom and balcony for 250 euros per month．
Currently only three flats are available．but the scheme is part of a wider effort to deal with a lack of accommodation for young people in the capital．Ordinarily a studio costs about 600 euros a month，depending on the area，one local university advises．
Those who apply don't need any specific care experience．"There are staff to look after the elderly．"project manager Miki Mielonen tells Yle．"We are looking for young people who maybe have a different perspective on everyday life，who will bring variety and recreation to the elderly residents．"
More than 60 people have applied for the spaces in less than a week，and the idea has also been widely recognized by Finns on social media．"Great project，hopefully it will spread to other areas，"writes one person on Facebook，while another applauds the scheme for bringing different generations together．
But some wish it was open to more people，with one user saying："It's a shame the flats are so small．It would have been nice if the elderly had a small family with children or a single parent as their neighbour．"And one person has a different opinion about the cut-off age，writing："Shame I'm too old for this-I would have surely applied．"
24．One can probably get the cheap apartment if heC．
A．reaches the age of 25
B．has financial problems
C．promises to accompany the elderly
D．agrees to share it
25．Why is the new rent scheme accepted？A
A．It can benefit both young and old．
B．It doesn't need any professional training．
C．The flats are well-equipped．
D．Big apartments are in short supply．
26．What does the underlined sentence suggest？C
A．He doesn't want to grow up．
B．He has a chance to apply again．
C．He disapproves of the age limit．
D．He applies for the flat without hesitation．
27．What would be the best title of the text？A
A．Young Finns offered cheap flats at care home
B．New apartments designed for the elderly
C．A new approach to caring for the old
D．A good chance for the needy families．

12．The environment is everything that surrounds us：plants，animals，buildings，country，air，water---everything that can affect us in any way．The environment of a town，with its buildings and its noise and smells，is a far cry from that of the countryside，with its fields and crops，its wild and domestic animals and its feeling of spaciousness（辽阔）．And the environment differs in different parts of the world．
Ecology is the science of how living things exist together and depend on each other and on the local environment．Where an environment is peaceful，the ecology of an area is in balance．
Man is a part of the environment and has done more to upset the ecology than any other living things．He has poisoned the atmosphere and polluted both land and water．He has wasted the earth's natural resources with no thought for the future，and has thought out the cruel ways of killing his fellow men---and every other sort of life at the same time．
Since man has done so much damage，it is up to man to try to put matters right---if it is not already too late．If there is to be any solutions for our ills，that solutions lie in the hands of the young，and the sooner they start doing something about it，the better．
One of the main causes of the earth's troubles is that the world is overpopulated and that this overpopulation is growing at an ever increasing speed．At the same time we are using up our natural resources at an ever increasing speed with no hope for replacing them．
For many years the earth has been unable to provide enough food for these rapidly growing populations and the position is gradually becoming worse since the areas that were once rich have turned into deserts．
Even at this moment many of the earth's natural treasures are being destroyed，many valuable animals and plants are being killed off，and it is becoming increasingly difficult to grow enough food to prevent much of the earth's population from hunger．The situation is getting out of hand．Time is running out．But with your help，we may be able to save ourselves．Who cares？
61．What is the main theme of the passage？C
A．Environment
B．Overpopulation
C．Environment protection
D．Ecology and science
62．The environment isD．
A．almost the same in the world
B．different in different towns
C．almost the same in different towns
D．different from place to place
63．It can be inferred from the passage thatC．
A．man can do little to keep the ecological balance
B．the environment in town is worse than that in the countryside
C．to control the population is also a necessary way to keep the ecological balance
D．no one really cares about the earth．
64．The underlined word"upset"is closest in meaning toC？
A．worry     B．pollute        C．break        D．possess

C．we can do nothing about the natural resources
D．we can not make good use of our time．

11．The cultural and natural values of Kakadu National Park were recognized internationally when the Park was placed on the UNESCO World Heritage List．This is an international register of properties that are recognized as having outstanding cultural or natural values of international significance．Kakadu is the largest national park in Australia and is the second largest national park in the world．Kakadu is a biological wonderland，which is almost 8，000square miles．The wildlife in Kakadu National Park includes over 280kinds of birds，60kinds of native mammals，55kinds of freshwater fish，thousands of insects，and many reptiles（爬行动物），the most famous of which is the salt-water crocodile．All life in the park depends on water．
Kakadu is not only home to the wildlife but the area is also famous for the longest continuous human culture that exists in the world．Aborigines（土著） have been living in this area for at least 40，000years．The descendants（后裔） of these First Australians still live in Kakadu today．Kakadu contains one of the longest continuous records of rock art in the world，with around 5，000paintings，with rock sites dating back 25，000years．More than 1，000sites have been recorded．Kakadu has been given double World Heritage status by the United Nations．It is one of only 17of the 469World heritage Areas listed for both natural and cultural values．
It is Australia's largest national park，but it isn't just the size that surprises visitors-it is the sense of something very old and grand．Creation of the 500km escarpment（悬崖） began 2，000million years ago．Today those gorges are filled with rainforests，washed by waterfalls．
Kakadu is one of the world's special places．It is hard to pick the ideal time to visit Kakadu．In the wet season large areas of the park are closed to the public．It would not be possible to enter or exit from the park through the Kakadu Highway．Most of the people there agree that the best time to visit is at the end of the dry season．Some areas of Kakadu have restricted visiting times，and some are not open to the general public．Over 230 000tourists visit Kakadu National Park every year．As you enter Kakadu National Park，you will be required to buy a permit．Part of this money is paid to the Traditional Owners of the land and the rest is given to the repairs of the park．

10．It is very important for people to drink water in our everyday life．Many people believe they are supposed to drink eight glasses of water a day，or about two liters．Why？Because that is what they have been told all their life．But a recent report offers some different advice．Experts say people should obey their bodies； they should drink as much water as they feel like drinking．The report says most healthy people meet their daily needs for liquid by letting thirst be their guide．The report is from the Institute of Medicine，part of the National Academies．The report contains some general suggestions．The experts say women should get about 2.7liters of water daily．Men should get about 3.7liters．But wait--in each case，that is more than eight glasses．
There is one important difference．The report does not tell people how many glasses of water to drink．In fact，the experts say it may be impossible to know how many glasses are needed to meet these guidelines．This is because the daily water requirement can include the water content in foods．People do not get water only by forcing themselves to drink a set number of glasses per day．People also drink fruit juices and sodas and milk．They drink coffee and tea．These all contain water．Yet some also contain caffeine．This causes the body to expel（排出）more water．But the writers of the report say this does not mean the body loses too much water．
As you might expect，the Institute of Medicine says people need to drink more water when they are physically active．The same is true of those who live in hot climates．Depending on heat and activity，people could need two times as much water as others do．All this，however，does not answer one question．No one seems sure why people have the idea that good health requires eight glasses of water daily．
It may have started with a misunderstanding．In 1945，the National Academy of Sciences published some guidelines．Its Food and Nutrition Board（营养膳食） said a good amount of water for most adults was 2.5liters daily．This was based on an average of one milliliter（毫升）for each calorie of food eaten．But that was only part of what the board said．It also said that most of this amount is contained in prepared foods．

56．In experts'opinion，every day a person should drinkC．
A．as much water as he can
B．more than eight glasses of water
C．according to actual need for his body
D．when he comes in sight of water
57．What is mainly described in the second paragraph？C
A．People know about the daily water requirement．
B．People need water instead of all kinds of drink．
C．People get daily water not only from drinking．
D．People drink all kinds of drink every day．

C．tell the importance of drinking water daily
D．figure out a good amount of water daily．

9．Since the gene，called DAF-16in worms，was found in many animals and in humans，the finding could open up new ways to affect aging，immunity（免疫）and resistance in humans，the scientists said．
"We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits，such as immunity，"said Robin May of the University of Birmingham，who led the study．
Populations across the world are aging at a surprising pace，bringing potentially big challenges for health and social care systems．A study by Danish scientists last year found that half of babies born in the rich world today will live to celebrate their 100th birthdays．Scientists are eager to find out how people age to try to develop drugs to help them stay healthier as their lives extend．
"What we have found is that things like resistance and aging tend to go hand in hand，"May said in an interview．
May's team compared longevity，stress resistance and immunity in four related species of worm．They also looked for differences in the activity of DAF-16in each of the four species，and found that they were all quite distinct．
May said DAF-16was active in most cells in the body and was very similar to a group of human genes called FOXO genes，which scientists believe play a role in the aging process．
"The fact that subtle（微妙的）differences in DAF-16between species seem to have such an impact on aging and health is very interesting and may explain how differences in lifespan and related traits have arisen during evolution，"May said．

71．In which section may the text appear in a newspaper？B
A．Education． B．Science．
C．Entertainment． D．Culture．
72．According to MayA，．
A．resistance has a lot to do with aging
B．FOXO genes can be found in worms

A．New ways have been found to affect aging．
B．Babies in the rich world will all live longer．
C．Present social care systems are poorly managed．
D．Aging populations are causing more challenges．
74．From the text we know that DAF-16．C
A．is a gene that is only found in worms
B．can make people live longer
C．has an effect on aging and immunity
D．has been quite familiar to scientists
75．What can be the best title of the passage？A
A．Scientists Find Gene Linked to Aging
B．Population Aging Faster than Expected
C．How to Make People Live Longer
D．Gene Determines How Long We Live．

8．Britain's seed bank，the only one in the world aiming to collect all of the planet's wild plant species，has reached its goal of banking 10 percent by 2010．
The Millennium Seed Bank Project，run by Kew Gardens-one of the oldest botanical gardens-will officially deposit the 24，200th species on Thursday，a pink，wild banana from China．
More than 50 countries are now on board with Kew's giant task but vast places of the globe，including India and Brazil，still need to join in and donate seeds，director Paul Smith said．
The seed bank is one of the largest and most diverse in the world with more than 1.5 billion seeds．Its goal is to help protect the planet's bio-diversity during a time of climate change．
The wild banana seed is under threat of extinction（灭绝） in southwest China from agricultural development．It is a vital food source for Asian elephants and important for growing bananas for human consumption．
Stored at minus-20 degrees centigrade，so they can last for thousands of years，the seeds await the day that scientists hope never comes-when the species no longer exist in the wild．
It is a race against time，Smith said，because in the last decade alone，20 plants held in the bank have already been wiped out in the wild．He estimates that between a third and a quarter will become extinct this century．
"It is urgent and it is happening now．An area，the size of England，is cleared of primary vegetation（植被）every year．"Smith said．
Because most of the world's food and medicines come from nature，protecting wild plant species is quite important，scientists say．There are already many other seed banks safeguarding food crops，which only account for 0.6 percent of plant diversity．
For Kew's next goal-to collect a quarter of wild varieties by 2020-the botanists need 10 million pounds a year，or a further 100 million pounds on top of the 40 million they have already been granted．
56．What's the final purpose of the Britain's seed bank？C
A．To collect enough money for the project．
B．To safeguard food crops．
C．To protect wild plants from extinction．
D．To help scientists study wild plants．
57．The wild banana seed in China is in danger because ofA．
A．the expanding of farming work
B．the climate change in this area
C．the large number of Asian elephants
D．human's large consumption
58．We can learn from the passage thatB．
A．the seeds in the bank can be used now and then all over the world
B．India and Brazil haven't joined in the Seed Bank Project at present
C．there is only one seed bank in the world at present
D．the wild plants in places like India and China will never die out
59．What does the underlined word"it"in paragraph 7 refer to？B
A．The extinction of plant species．
B．The Millennium Seed Bank Project．
