题目内容

17．______ with the effect of the color change，the woman smiled with satisfaction．（　　）

A．

Pleased

B．

To please

C．

To be pleased

D．

Having pleased

分析这位女士对颜色变化的效果感到很高兴，她满意地笑了．

解答答案：A．本题中非谓语动词在句中做状语．非谓语动词在句中做状语时，它的逻辑主语就是主句的主语，即please的逻辑主语就是the woman，它们之间是被动关系，所以应该用过去分词pleased，故选A．

点评本题考查非谓语动词作状语．非谓语动词作状语时，应先找到它的逻辑主语，主句的主语就是非谓语动词的逻辑主语，然后判断两者之间的逻辑关系，即主被动关系（主动关系就用现在分词形式；被动关系就用过去分词）和时间关系（非谓语动词在主句的谓语动词之前就已经发生就用完成式；之后发生就用一般式）．

18．Do you want to live with a strong sense of peacefulness，happiness，goodness，and self-respect？The collection of happiness actions broadly categorized as"honor"help you create this life of good feelings．
Here's an example to show how honorable actions create happiness．
Say a store clerk fails to charge us for an item．If we keep silent，and profit from the clerk's mistake，we would drive home with a sense of sneaky excitement．Later we might tell our family or friends about our good fortune．On the other hand，if we tell the clerk about the uncharged item，the clerk would be grateful and thank us for our honesty．We would leave the store with a quiet sense of honor that we might never share with another soul．
Then，what is it to do with our sense of happiness？
In the first case，where we don't tell the clerk，a couple of things would happen．Deep down inside we would know ourselves as a type of thief．In the process，we would lose some peace of mind and self-respect．We would also demonstrate that we cannot be trusted，since we advertise our dishonor by telling our family and friends．We damage our own reputations by telling others．In contrast，bringing the error to the clerk's attention causes different things to happen．Immediately the clerk knows us to be honorable．Upon leaving the store，we feel honorable and our self-respect is increased．Whenever we take honorable action we gain the deep internal rewards of goodness and a sense of nobility．
There is a beautiful positive cycle that is created by living a life of honorable actions．Honorable thoughts lead to honorable actions．Honorable actions lead us to a happier existence．And it's easy to think and act honorably again when we're happy．While the positive cycle can be difficult to start，once it's started，it's easy to continue．Keeping on doing good deeds brings us peace of mind，which is important for our happiness．

51．According to the passage，the positive action in the example contributes to ourA．
A．self-respect
B．financial rewards

D．friendly relationship
52．The author thinks that keeping silent about the uncharged item is equal toB．

A．telling the truth to the clerk
B．offering advice to the clerk
C．asking the clerk to be more attentive
D．reminding the clerk of the charged item
54．How will we feel if we let the clerk know her mistake？C
A．We'll be very excited．
B．We'll feel unfortunate．
C．We'll have a sense of honor．
D．We'll feel sorry for the clerk．
55．Which of the following can be the best title of this passage．D

B．Importance of Peacefulness
C．Ways of Gaining Self-respect
D．Happiness through Honorable Actions．

5．Why Laughter Matters
Although most people believe that laughter is one of the nature's great treatments for a whole range of mental and physical diseases，it is still a serious scientific subject that researchers are trying to figure out．
"Laughter above all else is a social thing，"says Baltimore neuroscientist，Robert Provine，who has studied laughter for decades．"All laughter groups laugh‘ha-ha-ha'basically the same way．Whether you speak Mandarin，French or English，everyone will understand laughter．There is a pattern generator（发生器） in our brain that produces this sound．"
Laughing is our first way of communicating．Babies laugh long before they speak．No one teaches them how to laugh．They just do．People may laugh at a prank（恶作剧） on April Fools'day．But surprisingly，only 10to 15percent of laughter is the result of someone making a joke．Laughter is mostly about social responses rather to a joke．Deaf people laugh without hearing and people on cell phones laugh without seeing，showing that laughter isn't dependent on single sense but on social interactions．
And laughter is not just a people thing．Chimps tickle（挠痒） each other and even laugh when another chimp pretends to tickle them．
Jaak Panksepp，a Bowling Green University Psychology professor，studies rats that laugh when he tickles them．It turns out rats love to be tickled-they return again and again to the hands of researchers tickling them．
By studying rats，scientists can figure out what's going on in the brain during laughter．Northwestern University biomedical engineering professor，Jeffrey Burgdorf has found that laughter in rats produces a chemical that acts as an antidepressant（抗抑郁药）．He thinks the same thing probably happens in humans，too．This would give doctors a new chemical target to develop drugs that can fight depression．
Even so，laughter itself has not been proved to be the best medicine，experts said．Margaret Stuber，a professor at University of California，studied whether laugher helped patients．She found that distraction（分心） and mood improvement helped，but she could not find a benefit of laughter alone．
"No study has shown that laughter produces a direct health benefit，"Provine said，largely because it's hard to separate laughter from just feeling good．But he thinks it doesn't really matter："Isn't the fact that laughter feels good when you do it enough？"

67．The most important finding of Robert Provine's research is thatA．
A．laughter makes a person feel good
B．laughter depends on different senses
C．laughter is a quality people are born with
D．laughter is a social response shared by all creatures
68．According to the passage，scientists studied rats in order to findC．
A．if they can laugh
B．if they like laughing
C．what laughter in rats produces
D．how rats react while being tickled
69．What can we learn from the passage？B
A．Patients will recover if they laugh enough．
B．Laughter is a means of communication as well as language．
C．A new medicine has been developed based on the laughter research．
D．Scientists can know what is happening in a human brain when he laughs．
70．Which of the following shows the structure of the passage？D

CP：Central point P：Point Sp：Sub-point（次要点） C：Conclusion．

2．A new set of R's is here：Recycle，Reduce and Reuse．These three"Rs"，when used every day，can reduce the amount of waste going into landfills，reduce the litter polluting the land and water，conserve（节约，保存）energy and save you money．
Recycling is one of the easiest ways to save energy，money and time while reducing the amount of garbage going into landfills．
Most communities have roadside pick-up service to recycle common household items like glass，steel，aluminum，newspaper and cardboard．By separating out the recyclable items from normal household trash，you can reduce the amount of trash entering a landfill by more than 75percent．
Recycling one aluminum beverage can（饮料罐）saves enough energy to run your television for three hours．Even better，local recyclers or scrap-metal dealers may pay money for your metal recyclables．
It is estimated that the 54billion cans recycled last year in the US saved l5million barrels of oil．That is equivalent（相等的）to the US oil consumption for one day．Recycling other household items offers similar savings in money and energy．
Composting food waste will reduce your trash load even more．A basic compost pile built with the help of instructions from numerous resources on the web can be constructed over a weekend，using materials easily obtained from local hardware or home improvement stores．In addition to reducing your waste，this all-natural recycling provides safe，clean and organic fertilizer for your garden，eliminating the need to buy chemical-derived products．
Finally，recycling other household items like computers，televisions and monitors and household chemicals like pesticides（农药）and paints will remove dangerous chemicals like mercury（水银）and lead from the landfills．
If your community doesn't offer recycling programs，contact your local government to get one established．

46．What's WRONG about recycling in the eyes of the author？C
A．It's energy-efficient．    B．It's money-saving．
C．It's time-consuming．      D．It's environmentally friendly．

9．BANGKOK-The tiny island nation of Tuvalu has promised to do its part for climate change by fueling its economy entirely from renewable sources by 2020．
The South Pacific nation of 12，000people is part of a movement of countries and cities committed to going climate neutral．Since February 2008，10nations have promised to reduce their emission（释放）of greenhouse gases as part of a goal of reaching zero emissions in the next decade．
None of these commitments alone is expected to make a significant difference in the fight to cut heat-trapping gases．But the moves can inspire bigger emitters（排放者）like the United States to take further steps to limit their carbon footprints．
Climate scientists have urged rich countries to reduce emissions from 2005levels by between 25percent and 40percent by 2020to avoid the worst effect of warming．For its parts，Tuvalu hopes to replace the fossil fuels that are imported by ship with solar energy and wind power soon．
Tuvalu already emits almost no greenhouse gases．But because of climate change，many South Pacific islands see worsening flooding．The country is just 10square miles in size，with most of its land less than a meter above sea level．
So far，Tuvalu has equipped a 40-kilowatt solar energy system with the help of Japan's Kansai Electric Power Co．and Tokyo Electric Power Company．The Tuvalu government is working to expand the $410，000project from 40to 60kilowatts，and will extend solar power to outer islands．
"We thank those countries who are helping Tuvalu reduce its carbon footprint，"Public Utilities and Industries Minister Kausea Natano said．"And we look forward to the day when our nation offers an example to all-powered entirely by natural resources such as the sun and the wind．"

53．What is the main energy source in Tuvalu at present？B
A．Solar energy
B．Imported fossil fuels
C．Wind powder
D．Local fossil fuels
54．For Tuvalu，the biggest trouble now is thatA．
A．it is under threat from rising sea level
B．it lacks enough natural resources
C．Climate change affects its economy
D．it lacks clean power equipment
55．What can we learn from the passage？C
A．It is impossible for Tuvalu to realize its goal．
B．The world will see zero emissions in ten years．
C．Tuvalu imports technology to reduce emissions．
D．Big countries haven't started to reduce emissions．
56．The best title for the passage might be"D"．

6．James Arruda Henry，a 98-year-old retired lobsterman，has written and published his first book，"In a Fisherman's Language"，after learning to read at the incredible age of 91．
Mr．Henry spent most of his life without even his closest family members knowing he was illiterate （文盲）．Forced to quit school in the third grade to take some jobs，he kept the secret close to his chest-only telling to his late wife．
A family problem in his 90s sparked his encourage to restart his education．"He signed a document he could not read，"Mr．Henry's granddaughter said．And then，after hearing about George Dawson，a son of slaves who learned to read at the age of 98 and went on to write a book of his own，entitled"Life Is So Good"at the age of 101，Mr．Henry took up reading．
"If he can do it．I'm going to try，"Mr．Henry said．Starting with his name．he eventually moved on to ABC's and children's books．He put them down for four years after the tragic loss of his wife．But eventually he went back to reading and with the help of his tutor began to record his life．
He wrote about his family's voyage from Portugal to the U．S．his many journeys at sea and how he was unable to save another fisherman who had fallen overboard．He became a carpenter and even a professional boxer-and eventually built his own home in Stonington Borough．
His life stories have become so popular，in fact，nearly 800 copies were sold in the first two weeks of the book's release last month．One thousand more have since been printed as requests for the book flood in from as far as Germany．And now even Hollywood producers have approached Mr．Henry about optioning the rights to his life story for a big screen adaptation．

4．Smoking is the single worst thing you can do for your health．Fortunately，it's never too late to get the benefits of quitting．If you've tried to quit before and failed，it's time to make up your mind and try again．
Smoking is responsible for one of every five deaths．That includes 29% of all cancer deaths，87% of all lung cancer deaths，and nearly 20% of all deaths from cardiovascular disease．But long before smoking kills you，it ages you．You can see for yourself that smoking accelerates the drying and wrinkling of the skin．But there are less obvious effects as well．Indeed，smoking takes years away from your life．Nearly half of all chronic smokers die an average of 20 to 25 years before their time．
Besides an early death from cancer or heart disease，smoking can cause lung disorders．People who smoke over a pack a day have almost three times the risk of contracting pneumonia（肺炎） than that of nonsmokers．By lowering levels of estrogen（雌激素）in men and women，smoking speeds bone less．If a woman smokes a pack of cigarettes every day，she will enter menopause（更年期）with 5 to 10% less bone mass than a nonsmoker．
The good news is that no matter what your age is or how long you've smoked，you'll live longer if you quit today．The Coronary Artery Surgery Study examined nearly 2，000 long-term smokers over age 54．Those who quit had significantly lower death rates six years later than those who didn't．Even the oldest ex-smokers had a higher survival rate．
Not only will live longer if you quit，you'll feel better，breathe easier，and find that you have more energy．You'll have fewer respiratory infections，headaches，and stomachaches．What's more，you'll save money．Your clothes and breath won't smell unpleasant any longer．And your habit won't annoy-or threaten the health of-the people who live and work with you．

54．What is the passage mainly about？C
A．The ways of quitting smoking．
B．The harm of smoking to people．
C．The benefits of quitting smoking．
D．The relationships between smoking and diseases．
55．According to the passage，the percentage of deaths due to smoking isA
