There was great excitement on the planet of Venus this week．For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since．
The satellite was directed into an area known as Manhattan(named after the great Venusian astronomer Prof．Manhattan, who first discovered it with his telescope 20000 light years ago)．
Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to the feasibility(可行性)of a manned flying saucer landing on Earth．A press conference was held at the Venus Institute of Technology．
“We have come to the conclusion, based on last week’s satellite landing, ”Pro．Zog said, “that there is no life on the Earth．”
“How do you know this?” the science reporter of the Venus Evening Star asked．
“For one thing, Earth’s surface in the area of Manhattan is composed of solid concrete(混凝土)and nothing can grow there．For another, the atmosphere is filled with carbon monoxide(一氧化碳)and other deadly gases and nobody could possibly breathe this air and survive．”
“What does this mean as far as our flying saucer program is concerned?”
“We shall have to take our own oxygen with us, which means a much heavier flying saucer than we originally planned．”
“Are there any other hazards that you discovered in your studies?”
“Take a look at this photo．You see this ?dark black cloud? hovering over the surface of Earth? We call this the Consolidated Edison Belt．We don’t know what it is made of, but it could give us a lot of trouble and we shall have to make further tests before we send a Venus Being there．”
“If what you say is true, won’t this set back the flying saucer program several years?”
“Yes, but we shall proceed as soon as the Grubstart gives us the added funds．”
“Prof．Zog, why are we spending billions and billions of zilches to land a flying saucer on Earth when there is no life there?”
“Because if we Venusians can learn to breathe in an Earth atmosphere, then we can live anywhere．”

It was the end of my exhausting first day as waitress in a busy New York restaurant．My cap had gone away, my apron was stained and my feet ached．The loaded trays I carried felt heavier and heavier．Weary and discouraged, I didn’t seem able to do anything right．As I made out a complicated check for a family with several children who had changed their ice-cream order a dozen times, I was ready to quit．
Then the father smiled at me as he handed me my tip．“Well done, ”he said．“You’ve looked after us really well．”
Suddenly my tiredness vanished．I smiled back, and later, when the manager asked me how I’d liked my first day, I said, “Fine!” Those few words of praise had changed everything．
Praise is like sunlight to the human spirit; we cannot flower and grow without it．And yet, while most of us are only too ready to apply to others the cold wind of criticism, we are somehow reluctant to give our fellows the warm sunshine of praise．
Why －when one word can bring such pleasure? A friend of mine who travels widely always tries to learn a little of the language of any place she visits．She’s not much of a linguist, but she does know how to say one word －“beautiful”－in several languages．She can use it to a mother holding her baby, or to a lonely salesman fishing out pictures of his family．The ability has earned her friends all over the world．
It’s strange how chary(谨慎小心的)we are about praising．Perhaps it’s because few of us know how to accept compliments gracefully．Instead, we are embarrassed and shrug off the words we are really so glad to hear．Because of this defensive reaction, direct compliments are surprisingly difficult to give．That is why some of the most valued pats on the back are those which come to us indirectly, in a letter or passed on by a friend．When one thinks of the speed with which spiteful(恶意的)remarks are conveyed(传达), it seems a pity that there isn’t more effort to relay pleasing and flattering comments．
It’s especially rewarding to give praise in areas in which effort generally goes unnoticed or unmentioned．An artist gets complimented for a glorious picture, a cook for a perfect meal．But do you ever tell your laundry(洗衣店)manager how pleased you are when the shirts are done just right? Do you ever praise your paper boy for getting the paper to you on time 365 days a year?
To give praise costs the giver nothing but a moment’s thought and a moment’s effort－perhaps a quick phone call to pass on a compliment, or five minutes spent writing an appreciative letter．It is such a small investment－and yet consider the results it may produce．“I can live for two months on a good compliment, ”said Mark Twain．
So, let’s be alert to the small excellences around us－and comment on them．We will not only bring joy into other people’s lives, but also, very often, add happiness into our own．

The English and the Continentals
In England everything is the other way round．On Sundays on the Continent even the poorest person puts on his best suit, tries to look respectable, and at the same time the life of the country becomes gay and cheerful; in England even the richest lord(勋爵)or motor-manufacturer dresses in some peculiar(特别的, 罕见的)rags, does not shave, and the country becomes dull and sad．On the Continent there is one subject which should be avoided－the weather; in England, if you do not repeat the phrase “lovely day, isn’t it?” at least two hundred times a day, you are considered a bit dull．On the Continent people use a fork as though a fork were a shovel(铲子); in England they turn it upside down and push everything－including peas－on top of it．
On the Continent almost every nation whether little or great has openly declared at one time or another that it is superior to all other nations; the English fight heroic wars to combat these dangerous ideas without ever mentioning which is really the most superior race in the world．Continental people are sensitive and touchy(易生气的); the English take everything with a sense of humor－they are only offended if you tell them that they have no sense of humor．On the Continent the population consists of a small percentage of criminals, a small percentage of honest people and the rest are a vague transition(过渡, 转变)between the two; in England you find a small percentage of criminals and the rest are honest people．On the other hand, people on the Continent either tell you the truth or lie; in England they hardly ever lie, but they would not dream of telling you the truth．
Many continentals think life is a game; the English think cricket is a game．

According to a recent poll, 61 percent of America high school students have admitted to cheating on exams at least once．It can be argued such a response may not mean much．After all, most students have been faced with the temptation to peek at a neighbor’s test paper．And students can be hard on themselves in judging such behavior．However, there are other indications that high school cheating may be on the rise．
More and more states are requiring students to pass competency(能力)tests in order to receive their high school diplomas(文凭)．And many educators fear that an increase in the use of state exams will lead to a corresponding(相应的)rise in cheating．A case in point is students in New York State who faced criminal misdemeanor charges for possessing and selling advance copies of state Regents examinations．
Cheating is now considered to be a major problem in colleges and universities．Several professors say they’ve dropped the traditional term paper requirement because many students buy prewritten term papers, and they can’t track down all the cheaters anymore．Colleges and universities across the nation have decided to do more than talk about the rise in student cheating．For instance, the Department of Psychology at the University of Maryland launched a campaign to stop one form of cheating．As 409 students filed out of their exam, they found all but one exit blocked．Proctors(监考人)asked each student to produce an ID card with an attached photo．Students who said they’d left theirs in the dorm or at home had a mug shot taken．The purpose of the campaign was to catch “ringers”, students who take tests for other students．
The majority of students at the University of Maryland applauded the campaign．The campus newspaper editorial said, “Like police arresting speeders, the intent is not to catch everyone but rather to catch enough to spread the word．”
Many educators feel that as students gain confidence in themselves and their abilities, they are less likely to cheat．Surprisingly, some efforts to prevent cheating may actually encourage cheating－a person may feel “they don’t trust me anyway, ”and be tempted to “beat the system．”Distrust can be contagious(传染的)．But, so can trust!
(1)
An increase in the use of state exams may result in ________．
[ ]
A．
more states requiring students to pass competency tests
B．
more students receiving high school diplomas
C．
a drop in criminal misdemeanor charges
D．
a rise in high school cheating
(2)
The purpose in making students produce an ID card with a photo when they take an exam is ________．
[ ]
A．
to make students more aware of the great amount of cheating going on
B．
to catch bright students who sell the information they remember to other students
C．
to catch students who take tests for other students
D．
to compare test results of students who sat near each other
(3)
The campaign launched by the Department of Psychology at the University of Maryland is cited as an example to show that ________．
[ ]
A．
students can be hard on themselves in judging some behavior as cheating
B．
proctors are very clever at tracking down cheaters
C．
colleges and universities have resolved to do more than talk about the rise in student cheating
D．
psychology professors are determined to catch all those who take tests for their fellow students
(4)
According to the campus newspaper editorial, the purpose of the campaign was ________．
[ ]

American scientist Morse Solomon has developed an unusual method to make meat softer．First, put a kilogram or more of firm meat in a container filled with water．Add a small amount of explosives．Then, mix carefully and explode．
No, Mister Morse is not attempting to destroy the meat．Instead, he is making it softer and also killing harmful bacteria．Mister Solomon is a meat scientist with the United States Agricultural Research Service．He began to explore the use of shock waves to soften meat ten years ago．His method is called the Hydrodynamic Pressure Process．The theory is simple．Shock waves from an explosion travel through water to the meat．The shock waves tear small pieces of muscle and other particles away from the meat．This makes the meat softer and easier to eat．The shock waves also reduce the amount of bacteria in the meat．The Department of Agriculture says the process could increase food safety for companies that sell meat．Uncooked meat may contain organisms such as the Escherichia coli bacteria, also known as E．coli．E．coli can make people sick if they eat meat that is not well cooked．The Hydrodynamic Pressure Process may help reduce concerns about harmful bacteria in meat．
Other American scientists attempted to improve the process．They used a thick-walled metal container that was buried in the ground．This device did not improve the quality of the meat as much as the simpler method．However, the scientists found there seemed to be fewer bacteria in the meat than before the process．Scientists had demonstrated that the Hydrodynamic Pressure Process could improve large pieces of meat．Next, they wanted to see if the process reduced bacteria levels in smaller pieces of ground beef that is used to make hamburgers．Their tests showed a reduction of bacteria in ground beef products．Other studies showed that ground beef containing E．coli had no measurable levels of the bacteria after the treatment．
The Hydrodynamic Pressure Process does not kill all bacteria in the meat, however．Mister Solomon says some good bacteria remain．The agricultural scientists say more studies are needed to see if the method could be used in the meat processing industry．

Netizens name the “father of hybrid rice” for Nobel prize
BEIJING, Nov．25－If netizens, rather than a selected group of experts, could choose Nobel Peace Prizes, a Chinese scientist might be a winner．
An Internet post last Tuesday calling for Chinese agricultural scientist Yuan Longping to be awarded next year’s Nobel Peace Prize got 20 000 votes by this Friday．Yuan is known as the “father of hybrid rice” in China．
A post written by a netizen called “Tiannan Dibei” on bbs．rednet．cn called for Yuan’s nomination．It cited Nobel Peace Laureate Mother Teresa in 1979 for her contribution to global charity, and Norman Borlaug in 1970 for his invention of a high-yield wheat useful for developing countries．
“The Nobel Peace Prize does not limit its winners to politicians and organizations devoted to the prevention of war, ” the post said．“It’s also open to people and organizations who try to eliminate problems and narrow the wealth gap．”
“Elimination of poverty and hunger is creating peace, ”it said．“With his extraordinary contribution to grain growth in the country and the world, Yuan is fully qualified for the prize．”

This year’s Nobel Peace Prize went to Muhammad Yunus and the Grameen Bank for their continuous efforts to grant small sum loans to the poor．
This Friday, more than 94 percent of more than 8500 people surveyed were in favor of Yuan getting the prize．
Yuan, a household name in China, is regarded as the most famous farmer in the country．He is noted for inventing a form of rice with a much higher yield than average crops．
With more than half of China’s paddy fields growing Yuan’s rice, his invention has fed millions of people in the world’s most populous country．

Among all the malignancies, lung cancer is the biggest killer； more than 100 000 Americans die of the disease．Giving up smoking is one of obvious ways to reduce the risk, but another answer may lie in the kitchen．According to a new report, even heavy smokers may be protected from developing lung cancer by eating a daily portion of carrots, spinach or any other vegetable or fruit containing a form of vitamin A called carotene(胡萝卜素)．
The finding, published in THE LANCET, is part of a long-range investigation of diet and disease．Since 1957, some American researchers have monitored the dietary habits and medical histories of 2000 middle-aged men employed by the Western Electric Co．in Chicago．Led by Dr．Richard Shekelle of St．Luke’s Medical Center, the researchers recently began to sort out the links between the subjects’ dietary patterns and cancer．Other studies of animals and humans have suggested that vitamin A offers some protection against lung cancer．The correlation seemed logical, explains Shekelle, since vitamin A is essential for the growth of the epithelial(上皮的)tissue that lines the airways of the lungs．
Vegetables：But the earlier research did not distinguish between the two different forms of the vitamin．“Preformed”vitamin A, known as retinol(维A醛), is found mainly in liver and dairy products like milk, cheese, butter and eggs．But vitamin A is also made in the body from carotene, which is abundant in a variety of vegetables and fruits, including carrots, spinach, squash, tomatoes, sweet potatoes and apples．
In the study, Shekelle and his colleagues found little correlation between the incidence of lung cancer and the consumption of foods containing preformed vitamin A．But when they examined the data on carotene intake, they discovered a significant relationship．Among the 488 men who had the lowest level of carotene consumption, there were 14 cases of lung cancer； in a group of the same size that ate the most carotene, only two cases developed．The apparent protective effect of carotene held up even for long-time smokers－but to a lesser degree．
Further studies will be necessary before the link between lung cancer and carotene can be firmly established．In the meantime, researchers warn against taking large numbers of vitamin A pills, because the tablets contain a form of the chemical that can be extremely toxic in high doses．Instead, they advise a well-balanced diet that includes goods rich in carotene．For a smoker, a half-cup of carrots every day might possibly make the difference between life and death．

Happy birthday!Do birthdays really make people happy?Of course they do．Birthdays celebrate the day we were born．Besides, that extra candle on the cake suggests another year of growth and maturity(成熟)－ or so we hope．We all like to imagine that we’re getting wiser and not just older．Most of us enjoy seeing the miracle(奇迹)of growth in others, as well．For instance, seeing our children develop and learn new things makes us feel proud．For Americans, like people in most cultures, growing up is a wonderful process(过程)．But growing old?That’s a different story．
Growing old is not exactly pleasant for people in youth-oriented(以年轻人为中心)American culture．Most Americans like to look young, act young and feel young．As the old saying goes, “You’re as young as you feel．”Older people joke about how many years young they are, rather than how many years old．People in some countries value the aged as a source of experience and wisdom．But Americans seem to favor those that are young, or at least“young at heart”．
Many older Americans find the“golden years”to be anything but golden．Economically, “senior citizens”often struggle just to get by．Retirement(退休)at age 65 brings a sharp decrease in personal income．Social security(安全)benefits usually cannot make up the difference．Older people may suffer from poor nutrition(营养), medical care and housing．Some even experience age discrimination．In 1987, American sociologist Pat Moore dressed up like an older person and wandered city streets．She was often treated rudely－even cheated and robbed．However, dressed as a young person, she received much more respect．
Unfortunately, the elderly population in America is increasing fast．Why?People are living longer．Fewer babies are being born．And middle-aged“baby boomers”are rapidly entering the groups of the elderly．America may soon be a place where wrinkles(皱纹)are“in”．Marketing experts are already noticing this growing group of consumers．
