Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people.
There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903, Jack met every boat in the area and showed it the way. Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack. He recovered and for nine years more continued to guide all ships through the area－except for The Penguin.
Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.

A group of graduates, well established in their careers, were talking at a reunion and decided to visit their old university professor, now retired. During their visit, the conversation turned to complaints about stress in their work and lives.
Offering his guests hot chocolate, the professor went into the kitchen and returned with a large pot of hot chocolate and other things including cups-porcelain(瓷杯子), glass, crystal, some plain looking, some expensive, some elegant -- telling them to help themselves to the hot chocolate.
When they all had a cup of hot chocolate in hand, the professor said: "I notice that all the nice looking and expensive cups were taken, leaving behind the plain and cheap ones. While it is normal for you to want only the best for yourselves, that is the source of your problems and stress. The cup that you"re drinking from adds nothing to the quality of the hot chocolate. In most cases it is just more expensive and in some cases even hides what we drink. What all of you really wanted was hot chocolate, not the cup; but you consciously went for the best cups... And then you began eyeing each others cups. Now consider this: Life is the hot chocolate; your job, money and position in society are the cups. They are just tools to hold and contain life. The cup you have does not define, nor change the quality of life you have. Sometimes, by concentrating only on the cup, we fail to enjoy the hot chocolate we have. The happiest people don"t have the best of everything. They just make the best of everything that they have. Live simply. Love generously. Care deeply. Speak kindly. Thank the Lord for your blessings in 2011. And enjoy your hot chocolate in 2012!”

Scientists at the California Institute of Technology (Caltech) have reported evidence that Mars was warmer and wetter long ago than it is today. The Caltech scientists say they have directly established the temperature of Mars four billion years ago. At least, they established the surface temperature on part of the planet at that time. The researchers say it is the first such evidence to be discovered and presented.
The Caltech scientists say carbonate（碳酸盐） minerals formed on Mars at about eighteen degrees Celsius. They reached the finding after studying a meteorite（陨石） that had its beginnings near the Martian surface.
Today, the average temperature on Mars is sixty-three degrees below zero Celsius.
The finding was reported on the website of the National Academy of Sciences. Caltech Assistant Professor Woody Fischer helped to prepare the report. He says eighteen degrees Celsius is not especially cold or hot. He says this makes the finding extremely interesting. Knowing the temperature can give scientists an idea of the climate on Mars long ago. It can also help them decide whether the planet had liquid water. Spacecraft orbiting Mars have shown what appear to be rivers, lakebeds and mineral deposits. These pictures suggest that, at one time, water did flow there. Mars Rover vehicles and other spacecraft have confirmed the information.
Caltech Geology Professor John Eiler was another writer of the report. He says knowing the temperature of Mars from long ago provides valuable information. It shows that early in the planet"s history, at least part of Mars could support a climate like that of Earth.
The meteorite the scientists examined is one of the oldest known rocks in the world. It is called the Allan Hills meteorite. Its name came from the place in Antarctica where it was found in 1984. The meteorite is believed to have blown loose from the Mars" surface when another space rock struck its "home."
小题1: The underlined word “establish” in Paragraph 1 probably means “___________”.
| A．to set up |
| B．to make people accept a belief |
| C．to discover or prove |
| D．to start having a relationship with others |
| A．By studying Allan Hills meteorite. |
| B．By using spacecraft orbiting Mars. |
| C．By studying minerals gathered on Mars |
| D．By studying a meteorite on the Martian surface. |
| A．Measuring the temperature of Mars. |
| B．Taking photos of the surface of Mars. |
| C．Confirming that there is water flowing on Mars. |
| D．Finding where human beings will probably land on Mars. |
| A．From its original place on Mars. |
| B．From where it was found on the earth. |
| C．From the name of the scientist who found it. |
| D．From the name of the aircraft that discovered it |
| A．In a biography of scientists. |
| B．In a geography magazine. |
| C．In an environment report. |
| D．In a science report. |
One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.
Another technological advance which is still in the experimental stage is the robot, a real “mechanized hired hand” that will be able to move and, in some ways, think like a human being. Agricultural engineers believe that computer-aided robots will make startling changes in farming before the end of the century. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear sheep, drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the barn, then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. The complete mobilization of the farm is far in the future, but engineers expect that some robots will be used before long.

First of all, mistakes are a clear sign that you are trying new things． It’s always good to try new things because when you are trying new things you are growing． If you never try anything new, how can you improve? How can you expand? The simple answer is “You can’t”． Look around you． With very few exceptions, either everything you see in your physical world or every single detail of every single thing is the result of someone trying something new．
Another good thing about mistakes is this: When you are making mistakes, you are learning． Consider this: Edison failed 10,000 times before he perfected the light bulb． When asked how it felt to fail that many times, he said that he hadn’t failed 10,000 times, but rather had learned 10,000 things that didn’t work．
Finally, when you make a mistake you are much closer to success． Why?
Because when all is said and done, you will have tried some number of things before you succeeded． Every time you make a mistake you eliminate one of those things and are one step closer．
But this all doesn’t mean that you should go ahead without considering the consequences of a mistake． Quite the contrary, when you try something new you have to be willing to set some reasonable limits so that in the event that it doesn’t work out the way you want it to, you will be in a position to try again．
We all have limited resources in the form of time and money so don’t blow them all on one approach to a problem． Realize that it probably won’t be perfect the first time and allocate （分配） these resources appropriately so you can learn, make corrections, and try it again． Only by accepting and using your mistakes in this way can you make significant advances in your business and your career．
There is an old saying that goes, “If you’re not making mistakes, you’re not trying hard enough．”
So go forth and make mistakes． And learn． And grow． And prosper（成功）．
小题1:From the second paragraph, we can conclude that _______．
| A．mistakes are unnecessary for development |
| B．we are afraid of trying new things |
| C．it’s common for people to make mistakes |
| D．mistakes are better than not trying |
| A．avoid | B．remove | C．accept | D．solve |
| A．avoiding making the same mistakes |
| B．accepting the punishment willingly |
| C．taking consequences into account |
| D．trying things out one by one |
| A．Never mind, I can always try again． |
| B．I’d better stay out of trouble． |
| C．Ok! Now I can learn something． |
| D．Look at this mess． Anyone would be upset． |
Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study, which involved twenty young women who worked for international airlines. They had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights. The other half spent more than fourteen days in their home areas.
The researcher took some saliva from the women”s mouths to measure levels of a hormone(荷尔蒙) that increases during stress(紧张). He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains to measure the size of the brain”s temporal lobes(脑叶).
It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones.
The researcher believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory.
Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find out if too much jet lag could permanently (永久性的) affect memory.
