Every profession，every art，and every science has its technical vocabulary. Its function is partly to name things or processes which can not be described in ordinary English．Such special terms are necessary in technical discussion of any kind．Being universally understood by the specialists of the particular science or art，these terms have the exactness of a mathematical formula（公式）．Besides，they save time, for it is much more convenient to name a process than to describe it．
Different occupations，however，differ widely in the character of their special vocabularies．In trades and handicrafts，and other professions，like farming and fishery，that have occupied great numbers of men in the past，the technical vocabulary is very old．It consists largely of native words, or borrowed words that have worked themselves into the very fibre of our language．As a consequence, though highly technical in many particulars，these vocabularies are more familiar in sound；and more generally understood，than most other technicalities．
Yet every profession still possesses a large body of technical terms that remain extremely unfamiliar, even to educated speech．And the amount has been much increased in the last fifty years．New terms are invented with the greatest freedom，and abandoned unconcernedly when they have served their turn．Most of the new inventions of words and expressions are restricted to special discussions, and seldom get into general conversation．
Yet no profession is，nowadays，as all professions once were，a closed association．Specialists in different fields share ideas and associate freely with each other. Furthermore, what is called “popular science” familiarizes everybody with modern views and recent discoveries. Any important experiment, though made in a remote lab, is at once reported in the newspaper, and everybody is soon talking about it—as in the case of the Roentgen rays and wordless telegraph. Thus our common speech is always taking up new technical terms and making them commonplace.

Scientists have discovered a special biological behavior in dolphins（海豚） that could lead to a treatment for late-onset diabetes（晚发的糖尿病） in humans. Studies on dolphins found that healthy dolphins switch into a diabetic-like state overnight when they are not feeding, but return to normal when they eat the following morning.
The extraordinary finding has led scientists to suggest that dolphins have “genetic switch” that allows them to imitate diabetes while they are not feeding for a night, without suffering any ill effect.
If researchers can identify a similar genetic pathway in human, they may be able to develop drugs to effectively switch off diabetes. Some 2.2 million people in Britain have type 2 (or late-onset) diabetes, a figure that is expected to reach 4 million by 2025 as a consequence of rising levels of obesity（肥胖）.
The tissues of people with type 2 diabetes have become resistant to insulin（胰岛素）so they lose the ability to control sugar levels in their blood. The condition can damage the heart, eyes, kidneys（肾脏） and nerves and contribute to 5% of all deaths, according to the World Healthy Organisation.
Dolphins appear to imitate diabetes to keep high levels of blood sugar when food is rare. Like humans, dolphins need some sugar in their blood for their brains to function normally. Venn-Watson’s team analysed 1,000 blood samples（样本） from 52 dolphins while they didn’t eat anything overnight and fed in the morning. At night time, the dolphins’ metabolism（新陈代谢）changed greatly and showed similar characteristics to that seen in people with type 2 diabetes.
“It is our hope that this discovery can lead to new ways to prevent, treat and maybe even cure diabetes in humans,” said Stephanie Venn-Watson, director of clinical research at the National Marine Foundation in San Diego.What’s the main idea of the passage?
| A．Humans get some idea of treating diabetes from dolphins. |
| B．Dolphins can switch into a diabetic-like state overnight. |
| C．Humans can suffer the same disease as dolphins. |
| D．Dolphins should be fed regularly to avoid diabetes. |
The key to applying the finding to curing human diabetes lies in ____________.
| A．producing insulin in a larger amount |
| B．developing drugs from healthy dolphins |
| C．identifying a similar genetic pathway in human |
| D．analysing more blood samples from hungry dolphins |
Which of the following statements is TRUE according to the passage?
| A．Scientists have found a similar genetic switch in humans. |
| B．More British people will suffer type 2 diabetes due to obesity. |
| C．2.2 million people with type 2 diabetes die in Britain every year. |
| D．Dolphins imitate diabetes to avoid a high blood sugar level. |
What will happen to dolphins if not fed for a night according to Venn-Watson?
| A．Their metabolism breaks down. |
| B．They become resistant to insulin. |
| C．Their heart and kidneys are damaged. |
| D．They keep high levels of blood sugar. |
They baby is just one day old and has not yet left hospital. She is quiet but alert （警觉）. Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze（凝视） starts to lose its focus — until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?
Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise （同样地） when the researchers started with drumbeats and moved to spots.The experiment described in Paragraph 1 is related to the baby’s__.
| A．sense of hearing | B．sense of sight |
| C．sense of touch | D．sense of smell |
Babies are sensitive to the change in______.
| A．the size of cards | B．the colour of pictures |
| C．the shape of patterns | D．the number of objects |
Why did the researchers test the babies with drumbeats?
| A．To reduce the difficulty of the experiment. |
| B．To see how babies recognize sounds. |
| C．To carry their experiment further. |
| D．To keep the babies’ interest. |
Where does this text probably come from?
| A．Science fiction. | B．Children’s literature. |
| C．An advertisement. | D．A science report. |
Some people will do just about anything to save money. And I am one of them. Take my family’s last vacation. It was my six-year-old son’s winter break form school, and we were heading home from Fort Lauderdale after a weeklong trip. The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meetings in New York，So I had to get back. But that didn't mean my husband and my son couldn't stay. I took my nine-month-old and took off for home.
The next day, my husband and son were offered more credits to take an even later flight. Yes, I encouraged—okay, ordered—them to wait it out at the airport, to "earn" more Delta Dollars. Our total take: $1,600. Not bad, huh?
Now some people may think I'm a bad mother and not such a great wife either. But as a big-time bargain hunter, I know the value of a dollar. And these days, a good deal is something few of us can afford to pass up.
I've made living looking for the best deals and exposing （揭露） the worst tricks. I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in.
I tell you this because there is no shame in getting your money’s worth. I’m also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate to spend on a good haircut. It keeps its shape longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts. Why did Delta give the author's family credits?
| A．Their flight had been delayed. |
| B．They had early bookings. |
| C．They took a later flight. |
| D．Their flight had been cancelled. |
What can we learn about the author?
| A．She is very strict with her children. |
| B．She seldom makes a compromise. |
| C．She rarely misses a good deal. |
| D．She is interested in cheap products. |
What does the author do?
| A．She's a media person. | B．She's a housewife. |
| C．She's a teacher. | D．She's a businesswoman. |
What does the author want to tell us?
| A．How to expose bad tricks. |
| B．How to reserve airline seats. |
| C．How to spend money wisely. |
| D．How to make a business deal. |

Michael Joseph Jackson was born on August 29, 1958. He was born in Gary, Indiana. He was the seventh child out of nine children in his family. Michael was often physically abused (虐待) by his father, beaten up and also verbally （口头地） abused. But Michael also owed his success to his father’s being strict.
Michael was always an entertainer（艺人）. Even when he just joined school, he would perform in front of friends and classmates. Michael started his professional music career at the age of 11, as a member of the Jackson Five.
He’s well-known for increasing the popularity of MTV through his music videos. Before this, music videos were made just to promote the albums （专辑）. But Michael’s videos managed to change that in videos being made as an art, and for big business. Some of the music videos that are good examples of this fact are Beat It, Billie Jean, and Thriller. Through these works of his, the world got caught onto the idea of music videos and dedicated music video channels.
Michael enthralled his fans and audiences with his style of singing, dressing, and his complex dance moves, especially the “Moonwalk”. The moonwalk is something that people from every part of the globe loved and try to copy People have also done mass moonwalks all around to show their love towards him.
Michael Jackson supported 39 charities （慈善机构）. Through his work and various foundations, he raised and gave millions toward charity, much more than any other showman. He had great love for children, especially the poor ones, and he felt children were the next best thing after God.
Michael planed to start a 50-concert tour in July 2009. Sadly, on 25th June, 2009, Michael passed away at home. Michael Jackson was a great performer, showman, and entertainer, besides the good human and charitable person that he was.
