　　Some inventions are so useful, but seem so simple, that we wonder why no one thought of them long ago. Post-it Notes—the pieces of pa per that you can fasten almost anywhere and then remove without leaving any sign that they were there—are an example of such an invention.

　　Post-it Notes were invented about twenty years ago by Art Fry, a scientist at 3M Corporation. The idea for the product came from a frustrating(令人沮丧的) experience he often had while singing in his church choir(唱诗班) . Fry used pieces of paper as bookmarks to mark the places in his book of songs, but these bookmarks were always falling out. He knew he needed a bookmark that would stay where he put it, but that he could remove without damaging the pages.

　　Around the time Fry lard about a new adhesive (粘合剂) that a (同事) , Dr. Spence Silver, had created. This adhesive was special because it was sticky, but not too sticky. It was strong enough to hold papers together, but weak enough not to tear the paper when it was removed. Fry saw that the new adhesive could help solve his bookmark problem. One morning, Fry put some of the adhesive on the edge of a piece of paper. Just as he hoped, it made a perfect bookmark.

　　Fry and some other people at 3M believed so much in the new product that they persuaded the company to give away thousands of the “sticky pieces of paper” for trial use. When some salespeople at 3M went to offices and showed workers just how helpful the new type of notes could be, they immediately received many orders. As more and more people discovered how useful Post-it Notes could be, the product took off.

If your head is overheating, you are very likely to yawn(打哈欠) soon, according to a new study that has found the main purpose of yawning is to control brain temperature. The study explains several mysteries about yawning, such as why it’s most commonly done just before and after sleeping, why certain diseases lead to too much yawning, and why breathing though the nose often stops yawning.
“Brains are like computers,” Andrew Gallup, a researcher in the department of Biology at Binghamton University who led the study, said. “They operate best when cool.”
He and his co-workers Micheal Miller and Anne Clark did researches on yawning in parakeets(长尾小鹦鹉) , which have relatively large brains, live wild in Australia, often experience temperature changes, and, most importantly, do not yawn when others yawn, as humans and some other animals do.
For the study, the scientists put parakeets under three different conditions: increasing temperature, high temperature and normal temperature. While the frequency(频率) of yawns did not increase under the latter two conditions, it increased greatly when the researchers increased the temperature.
It’s now believed yawning operates like a radiator(散热器).
If air in the atmosphere is cooler than the brain and body temperatures, taking it in quickly cools blood, which in turn cools the brain. The new findings also explain why tired people often yawn. Both tiredness and sleep loss can increase brain temperature, while yawning can cool down the brain.
In the future, researchers may focus more on brain temperature and its role in diseases and their symptoms. But the new study on yawning changes the popular idea that yawns are just signs of getting tired of something.
49. What’s the best title for the passage?
A. Why don’t people yawn at normal temperature?
B. The yawn explained—it cools your brain.
C. Yawning operates like a radiator.
D. The cause of yawning—finally found out.
50. The main reason why researchers chose parakeets to do the research is that parakeets______.
A. have very large brains
B. live wild in Australia
C. are not affected by others’ yawning
D. experience frequent temperature changes
51. The writer may suggest doing all of the following to stop yawning EXCEPT______.
A. breathing through the nose
B. turning up the heat
C. enjoying some cool wind
D. putting a cold towel on your forehead
52. In which section of a newspaper would you most probably read this passage?
A. Discovery.        B. Education.         C. Health.              D. Mystery.

It's certain:for twins,life really does imitate art.My twin brother,Kirk,and I grew up being constantly mistaken for each （处理这个问题） other.Classmates,friends,teachers,even relatives couldn't tell us apart. As a result,we were often unfairly punished or rewarded.

Eventually,we learned how to use the Mistaken Identity Syndrome (MIS) to our advantage.For example,we would play tricks on our friends and classmates,pretending to be the other twin.Nor were teachers immune(不受某事物影响) to our tricks.On at least one occasion,when Kirk was sick,I covered for (替代) him by taking his tests.We also tried our little game out on Mom,but she always knew who was who.Once we grew up，we even covered for each other at work.We didn't mean any harm;we simply started this as an experiment to see whether our bosses and co-workers could tell the difference.

As a bank manager, I meet with dozens of clients(顾客) on a daily basis, while my brother manages a staffing service for local employers. As a result, Kirk is constantly approached by people who want to discuss their various money accounts, while I'm frequently thanked on the street as a department store customer service representative.

However, the MIS took a truly embarrassing turn when Kirk and I found ourselves unable to tell each other apart. Once, my brother and I were traveling in a car with several friends. My brother's hair must always be in place. Kirk was driving when he noticed in the rearview mirror (后视镜) that his hair was a bit messy.

     For the tenth and last time as Secretary General, I offer friends and colleagues around
the world my best wishes on United Nations Day. I have spent almost all my whole
professional life working for the United Nations-sothisday , andthevaluesthatstand for ,
willal-ways be special for me.
     Over the past ten years, we have made some big steps forward in our common struggle
for development, security and human rights. Aid and debt relief have increased , making
the world economy somewhat fairer. At last, the world is increasing its response to
HIV/AIDS. There are fewer wars between States than there used to be , and manycivil
warshaveended. Moregovernments are elected by, and accountable to the people
whom they govern. And all States have acknowledged, at least in words, their
responsibility to protect people from genocide, war crimes, ethnic cleansing and
crimes against humanity.
     But there is so much that still needs doing.
     The gap between rich and poor continues to grow.
Thenuclearnon-proliferationregime (核不扩散机制) requires urgent attention.
Terrorism and the reaction to it are spreading fear and suspicion. It seems we don't
even agree which threats are most important. Those who live in small islands may
see global warming as the biggest danger. Those who live in a city that has suffered
terrorist attacks-likeNewYork , orMumbai, orIstanbul-may feel that confronting
terrorism is more urgent. Othersagainmaycitepoverty , disease , orgenocide. The
truth is , there are all global threats. All of us should be concerned about all of them.
Otherwise ,we may not succeed in dealing with any of them.
     At this time of all times. We cannot afford to be divided. I know that you, the people
of the world, understand this. Thank you for all the support and encouragement you have
given me, throughout these ten difficult but exciting years.
      Please urge your leaders to work with my successor, and make the United Nations
ever stronger and more affective.
     Long live our planet, and its peoples!Long live the United Nations!
