9．If you experience great stress in your life on a frequent basis.you're not alone．Nowadays.stress i——青夏教育精英家教网—

9．If you experience great stress in your life on a frequent basis，you're not alone．Nowadays，stress is almost a given fact of life．Actually，a certain degree of stress can have positive effects on us．But if stress continues over a long period of time，the effects on the body can be harmful，resulting in health problems and stress-related illness，including heart attack and stroke．
Stress is a normal reaction by the body to what it perceives （认为）as a threatening situation or environment．Short-term reactions may include an increase in heart rate as well as a rise in blood pressure．A person under short-term stress may feel nervous，anxious and even experience shortness of breath．Other reactions can include a dry mouth，quick heartbeat，sweating，stomach upset and diarrhea．
When stress is long-term and becomes more chronic （长期的） in nature，it can cause more serious health-related problems，including regular headaches，back pain，weight changes，sleep difficulties，changes in mood and so on．Chronic stress can also result in memory problems，including difficulty remembering new information and the inability to quickly deal with old information．
No matter how your body reacts to stress，ignoring the problem can have serious health results．Not surprisingly，more women than men openly seek the help of their family doctors or other health care experts when they are experiencing stress or stress-related illness．Men are more likely to refuse to admit the problem or attempt to self-treat it，which may contribute to higher rate of drug and alcohol addiction seen in men exposed to chronic stress．
There's no doubt that stress is a fact of life and is likely to remain a part of our fast-paced society．Although stress can't be completely eliminated，methods of dealing with stress-related issues，in my view，can be developed so that the effects of stress on the body are avoided，so people won't be so easy to suffer stress-related illness．

A．They should ignore it．
B．They should learn to deal with it on their own．
C．They should turn to drugs and alcohol for relief．
D．They should seek more methods of dealing with it．
30．What does the word"eliminated"in the last paragraph mean？B
A．reduced．
B．removed．
C．appreciated．
D．destroyed．
31．What is the purpose of this passage？C
A．To tell us how to solve the serious problems caused by stress．
B．To tell us how to behave well when we are faced with stress．
C．To tell us how to protect ourselves from the effects of stress．

8．Mr Wang is due to makecomments（评论） on the latest film next week．

7．Last year，CCTV journalists approached pedestrians with their cameras，held a microphone to their mouth and asked a simple question，"Are you happy？"
The question has caught many interviewees off guard．Even Mo Yan，who just won a Nobel Prize，responded by saying，"I don't know．"
While the question has become a buzz phrase and the Internet plays host to heated discussions，we ask：What exactly is happiness？And how do you measure it？
In the 1776US Declaration of Independence，Thomas Jefferson set in writing the people's unalienable right to"Life，Liberty and the Pursuit of Happiness".235years on，Wen Jiabao told the nation，"Everything we do is aimed at letting people live more happily．"At National People's Congress，officials agreed that increasing happiness would be a top target for the 12^thfive-year plan．
US psychologist Ed Diener，author of Happiness：Unlocking the Mysteries of Psychological Wealth，describes happiness as"a combination of life satisfaction and having more positive than negative emotions"according to US broadcasting network PBS．This may sound straightforward enough，but it still doesn't explain what determines people's happiness．
Many argue that happiness is elusive and that there is no single source．It also means different things to different people．For some，happiness can be as simple as having enough cash．
Researchers believe happiness can be separated into two types：daily experiences of hedonic （享乐的） well-being； and evaluative well-being，the way people think about their lives as a whole．The former refers to the quality of living，whereas the latter is about overall happiness，including life goals and achievements．Happiness can cross both dimensions （范围）．
Li Jun，a psychologist and mental therapy practitioner at a Beijing clinic，says，"Happiness can mean both the most basic human satisfaction or the highest level of spiritual pursuit．It's a simple yet profound topic．"
Chen Shangyuan，21，a junior English major at Nanjing University of Aeronautics and Astronautics，said his idea of happiness always evolves．"At present it relates to how productive I am in a day，"he said．"It might be linked to job security or leisure time after I graduate．"
Then there is the question of measuring happiness．Does it depend on how many friends we have，or whether we own the latest smart phone？Is it even quantifiable？
Economists are trying to measure happiness in people's lives．Since 1972，Bhutan's GDP measurement has been replaced by a Gross National Happiness index．It is calculated according to the peoples'sense of being well-governed，their relationship with the environment，their satisfaction with economic development，and their sense of national belonging．
In 2009，US economist Joseph Stiglitz proposed"to shift emphasis from measuring economic production to measuring people's well-being"．But is well-being more easily measured？
63．From what Thomas Jefferson and Wen Jiabao mentioned in the passage，we knowB．
A．people's happiness is determined by great people
B．people's happiness is an important target for the development of a country
C．people in all countries have the right to ask the government for a happy life
D．people both in China and America are living a happy life
64．According to the passage，the writer may most likely agree thatD．
A．CCTV journalists are concerned about people's happiness out of sympathy
B．the question has led to heated discussions about who are the happiest people in China
C．Bhutan's new index shows that people there are the happiest in the world
D．it is not easy for us to decide what determines people's happiness
65．What does the underlined word"elusive"in the sixth paragraph mean？C
A．available
B．easy to get
C．hard to describe
D．unimaginable
66．The best title of the passage isA．
A．Are you happy？
B．The Measurement of Happiness
C．GDP and Happiness
D．The Secret of Happiness．

6．Everyone is familiar with white fat，which serves as an energy warehouse．Many mammals also have brown fat，which has the unique ability to produce heat．
Brown fat is sometimes mistaken for a type of gland （腺），which it resembles more than white fat．It varies in color from dark red to tan．When the animal is exposed to a cold environment，the color darkens．In contrast to white fat，brown fat has numerous nerves which provide sympathetic stimulation （刺激） to the fat cells．
Brown fat is most noticeable in newborn animals，wrapped round the central organs to keep them warm．In humaninfantsit occupies up to 5% of body weight，then declines gradually．Certain quantities of brown fat can be discovered in adult humans，especially when they are exposed to cold temperatures．Most of brown fat in adults is located in the lower neck．
Exposure to cold leads to sympathetic stimulation of brown fat cell．As in white fat，sympathetic stimulation promotes hydrolysis （水解） of triglyceride （甘油三酸脂），with release of fatty acids．In contrast to other cells，including white fat cells，brown fat cells express UCP1，which gives the cell's mitochondria （线粒体） an ability to produce heat rather than ATP．Within brown fat cells，most fatty acids are immediately combined with oxygen in mitochondria and a large amount of heat is produced．
There is only about 50g of brown fat in the neck region and it switches on and off throughout the day as it's exposed to different temperatures or if you exercise or eat．But this capacity is much greater in young children compared with adolescents and adults．
The challenge is now to use the knowledge to find out what might switch on brown fat．If it is switched on，we can benefit from it．Brown fat produces lots of heat by burning calories．Unlike white fat，brown fat does not expand our ageing waistlines．And that's why the race is on to find out more about brown fat，and how humans could use it to our advantage，though we would waste energy unnecessarily，and we would sweat a lot and forever be opening windows．
59．We can learn from the passage that brown fatA．
A．becomes less in amount with age
B．proves less active in low temperatures
C．exists nowhere but in the lower neck
D．has nothing in common with white fat
60．The underlined word"infants"in Paragraph 3means"D"．
A．cells
B．organs
C．bodies
D．babies
61．We take special interest in brown fat mainly because it helps usD．
A．save energy
B．develop power
C．keep warm
D．keep our figure．

5．Silence is unnatural to man．He begins life with a cry and ends it in stillness．In between he does all he can to make a noise in the world，and he fears silence more than anything else．Even his conversation is an attempt to prevent a fearful silence．If he is introduced to another person，and a number of pauses occur in the conversation，he regards himself as a failure，a worthless person，and is full of envy of the emptiest-headed chatterbox（喋喋不休唠叨的人）．He knows that ninety-nine percent of human conversation means no more than the buzzing of a fly，but he is anxious to join in the buzz and to prove that he is a man and not a waxwork figure．
The aim of conversation is not，for the most part，to communicate ideas；it is to keep up the buzzing sound．There are，it must be admitted，different qualities of buzz；there is even a buzz that is as annoying as the continuous noise made by a mosquito．But at a dinner party one would rather be a mosquito than a quiet person．Most buzzing，fortunately，is pleasant to the ear，and some of it is pleasant even to the mind．He would be a foolish man if he waited until he had a wise thought to take part in the buzzing with his neighbors．
Those who hate to pick up the weather as a conversational opening seem to me not to know the reason why human beings wish to talk．Very few human beings join in a conversation in the hope of learning anything new．Some of them are content if they are merely allowed to go on making a noise into other people's ears，though they have nothing to tell them except that they have seen two or three new plays or that they had food in a Swiss hotel．At the end of an evening during which they have said nothing meaningful for a long time，they just prove themselves to be successful conversationists．
56．According to the author，people make conversation toD．
A．exchange ideas
B．prove their value
C．achieve success in life
D．overcome their fear of silence
57．By"the buzzing of a fly"（Para.1），the author meansC．
A．the noise of an insect
B．a low whispering sound
C．meaningless talks
D．the voice of a chatterbox
58．According to the passage，people usually talk to their neighborsB．
A．about whatever they have prepared
B．about whatever they want to
C．in the hope of learning something new
D．in the hope of getting on well．

4．One in three of us eat more meals by ourselves than we do with other people，a new study showed today．
But before you digest that somewhat depressing figures，there is some good news---kind of---a lot of us are perfectly happy to eat alone because the computer and TV provide us with solitary （独居的） entertainment．
Perhaps unsurprisingly，half of the UK's bachelors eat a meal alone at least once a day．And even one in four mothers with families have dinner mostly by themselves according to a major report on eating trends and social change by the Future Foundation．However，eating alone doesn't seem to matter anymore if you can chat away on social networks-in fact it's now both a quick and entertaining affair．
"Suppertainment"is the phrase being coined for the current major trend that reflects the number of people who eat in front of the computer，TV or games．Single men are the majority leading this trend，with 60percent of them spending meal times plugged into something．However，40percent of mothers and 30percent of students also eat meals while being on the PC or laptop several times a week．
Boyd Hilton，TV and reviews editor of Heat Magazine says："Setting yourself up in front of the TV to‘Suppertain'comes naturally，especially when you've been on the go all day．
"If I'm on my own I always tend to make a quick and easy meal and settle down to watch something entertaining or I'll get on the laptop and catch up with comedies．"
"I think it's such a bonus that healthy，tasty convenience meals now mean you can relax about eating good food without having to worry about preparation time．"

3．Don't be too sensitive to what other people say about you．Just be yourself．

2．The famous tourist attraction that arouses the greatest appreciation in the Changbaishan in Jilin is Tianchi or the Lake of Heaven．

1．A telescope （望远镜），called Gaia，is being designed by astronomers in Europe，and it couldn't be more different from Pan-STARRS，which is another telescope being designed．While Pan-STARRS will be looking for asteroids （小行星） and comets headed for Earth，Gaia will be looking at our entire galaxy （银河系）．
Gaia is designed to draw a map of the Milky Way，our home galaxy．Just as a map of your town gives you a picture of where things are located，Gaia's map of the galaxy will tell astronomers where the stars are．Over five years，Gaia will observe （观察） about a billion stars and other objects in our galaxy．Each object will be observed about 70times．
Gaia will be sent into space connected to a rocket．It contains two telescopes，each focused at a different angle （角度）．These two telescopes act like Gaia's"eyes"．The reason why humans can see things in 3D is that we have two eyes focused on the same object，at slightly different angles．By using two telescopes like eyes，Gaia can produce the first 3D map of the positions of the stars it views．
Gaia，which is to be sent into space in 2011，will be a powerful telescope．If you were to use it on Earth，for example，you could stand 600miles away from your best friends and still get a clear picture of their hair．
Gaia is one of more than a dozen telescopes being designed by scientists right now．The next generation of telescopes will reveal new parts of our universe that will seem surprising．The universe，with all its planets，stars and other strange objects，is a puzzle with pieces that we can see by using powerful telescopes．
17．How many different angles can Gaia focus at each time？A
A.2．
B.3．
C.4．
D.5．
18．The map to be drawn by GaiaD．
A．can show every building on Earth
B．can show you where your town is
C．will just show the stars around Earth
D．will show where the stars are in our home galaxy
19．What's Paragraph 4mainly about？C
A．What Gaia will do in space．
B．When Gaia will start to work．
C．How powerful Gaia will be．
D．What Gaia will do to Earth．
20．The underlined sentence in the last paragraph suggests that the next generation of telescopesD．
A．seem very surprising to scientists
B．will not be put into use in a short time
C．will just look at new things in universe
D．will be more powerful than the old generations．

20．Chilean miner Edison Pena plans to run the New York City Marathon on Sunday，less than a month after he was rescued from a collapsed （坍塌的） mine that trapped him for 69days．Pena ran 10km daily through the mine's tunnels （巷道） to beat the anxiety，wearing cut-down boots until rescuers sent him a pair of sports shoes through a narrow hole that served as the miners'"lifeline"to the surface．
"When I ran in the darkness，I was running for life，"Pena told a news conference in New York．"I was running to show that I wasn't just waiting around．I also wanted God to see that I really wanted to live．"
The New York Road Runners，which organizes the marathon，had invited Pena to be a guest at Sunday's race，but he said last week he did not want to watch，he wanted to run．"I was very eager to take on this big challenge，"he said．"I wanted to show the world I could run．"He hoped to run the 26.2-mile race in about six hours．"I have a knee injury，but I am eager to cross the finish line，"he said．Last year，Meb Keflezighi won the men's marathon in two hours，nine minutes and 15seconds．
An Elvis Presley fan who asked rescuers to send the singer's music down into the mine，Pena broke into song at the news conference with the Presley hit Return to Sender．The miners were discovered alive on August 22-17days after the mine collapsed，but it took two months for rescuers to dig a hole big enough to bring them out．
