If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation--conversion of liquid water to water vapor. In this manner, the salinity is increased, since the salts stay behind. If this is carried to the extreme, of course, white crystals of salt would be left behind.
The opposite of evaporation is precipitation(降水), such as rain, by which water is added to the ocean. Here the ocean is being diluted(稀释) so that the salinity is decreased. This may occur in areas of high rainfall or in coastal regions where rivers flow into the ocean. Thus salinity may be increased by the subtraction of water by evaporation, or decreased by the addition of fresh water by precipitation or runoff.
Normally, in tropical regions where the sun is very strong, the ocean salinity is somewhat higher than it is in other parts of the world where there is not as much evaporation. Similarly, in coastal regions where rivers dilute the sea, salinity is somewhat lower than in other oceanic areas.
A third process by which salinity may be altered is associated with the formation and melting of sea ice. When seawater is frozen, the dissolved materials are left behind. In this manner, seawater directly beneath freshly formed sea ice has a higher salinity than it did before the ice appeared. Of course, when this ice melts, it will tend to decrease the salinity of the surrounding water.
In the Weddell Sea, off Antarctica, the densest water in the oceans is formed as a result of this freezing process, which increases the salinity of cold water. This heavy water sinks and is found in the deeper portions of the oceans of the world.

It looked like a typical business meeting. Six men, neatly dressed in white shirts and ties filed into the boardroom of a small Jakarta company and sat down at a long table. But instead of ______ files or hearing reports, they closed their eyes and began to meditate, consulting the spirits of ancient Javanese kings. Mysticism touches almost every aspect of life in Indonesia and business is no ______. One of the meditators said his weekly meditation sessions are aimed mainly at bringing the peace of mind that makes for good decision-making. But the insight gained from mystic communication with spirits of wise kings has also helped ______ the profits of his five companies.

Or maybe the spirits will tell us he should be hired.’ Hadiziko hastened to add that his companies also hold modern personnel management systems and that formal ______ are essential for a candidate even to be considered. Perspective investments also are considered through mystic meditation. ‘With the mind relaxed and open, it is easier to be ______ in judging the risk of a new venture. Meditation and contact with the wisdom of the old leaders sharpens your own insight and intuition. Then you have to apply that intuition to the information you have and work hard to be successful.’ Mystic meditation helped ______ a business slide his companies experienced in the mid-1980. Operating with normal business ______, he lost more than $ 3 millions in that year alone. Meditation brought back his peace of mind. Putting the right persons in the right jobs and gaining confidence in his business decisions were the keys to a turning around that has brought ______ and profitability. The mysticism in Handspike’s boardroom is part of a growing movement in Indonesia called Kebatinan – the ‘search for the inner self.’

There is no denying that students should learn something about how computers work, just as we expect them at least to understand that the internal-combustion engine has something to do with burning fuel, expanding gases and pistons 1. (drive). For people should have some basic idea of how the things that they use do 2. they do. Further, students might be helped by a course that considers the computer’s impact on society. But that is not what is meant 3. computer literacy. Computer literacy is not a form of literacy; it is a trade skill that should not be taught as a liberal art.
Learning how to use a computer and learning how to program one are two distinct activities. A case might be made that the competent citizens of tomorrow 4. free themselves from their fear of computers. But this is quite different from saying that all ought to know how to program one. Leave that to people who have chosen programming as a career. While programming can be lots of fun, 5. while our society needs some people who are experts at it, the same is true of auto repair and violin-making.
Learning how to use a computer is not that difficult, and it gets easier all the time as programs become more “user-friendly”. Let us assume that in the future 6. is going to have to know how to use a computer to be a competent citizen. What does the phrase learning to use a computer mean? It sounds like “learning to drive a car”, that is, it sounds 7. there is some set of definite skills that, once 8. (acquire), enable one to use a computer.
In fact, “learning to use a computer” is much more like “learning to play a game”, but learning the rules of one game may not help you play 9. second game, 10. rules may not be the same. There is no such a thing as teaching someone how to use a computer. One can only teach people to use this or that program and generally that is easily accomplished.

What's the easiest way to stay warm in the super cold？1.. At least that's what Santa Claus told me.
Over Christmas, Dennis and I went to Finland. We brought back some tips for keeping warm in a cold temperature.
Three layers（层）work wonders.
Start with the base layer, which sits right on your skin: choose something absorbent（有吸收力的）.2..
A sweater is a good choice. The most important layer is the outer clothes, which should be waterproof（防水的）and windproof.
3..
You lose heat from every millimeter of uncovered skin, which was the biggest lesson I learned on the trip. My whole body was well covered. But I missed one spot: my face. So it often felt like the wind was going to blow my nose off.
Exercise and don't just stand still.
When it's cold, exercising may be the last thing you feel like doing, but be smart.4.. When we first got to Finland, we were freezing. But after a couple of minutes jumping around, we felt less cold.
Have a heater.
You may want to turn it on all the way up, but it's best to keep it between 18 and 20 degrees.5.. Remember not to create a huge difference between inside and outside.
A. Grow a crazy beard
B. Cover every bit of your skin
C. The key is what you layers are
D. That will keep you comfortable
E. Don't forget to keep your hands and feet warm, too
F. The middle layer keeps your body heat from getting away
G. Take a walk, faster than your normal speed, and you will feel the difference
With 10, 600 bicycles in circulation, Paris city officials are hoping the program will provide people with more environmentally friendly transportation.
It seems both Parisians and tourists are taking advantage of the program. Since its launch a little over two weeks ago, Vélib has already seen almost half a million rentals. And, with the addition of 10,000 more bikes and 700 more stations in the next 12 months, city officials expect at least 200,000 regular users by year end. Parisian Olivier Bioret has already gone for a spin on one of Vélib’s vehicles and plans to make use of them more often.
“It’s a real pleasure—when, like me, you don’t have space enough in your flat to have your own bike—to be able to discover, to cross Paris and not have to take the subway. ”he said．
As a socialist and longtime green activist, Mayor Bertrand Delanoe regards Vélib as just a part of his plan to reduce car traffic and, thus, lower pollution by 2020.
Apart from its environmental benefits, Vélib is also being praised as a way of collecting money for the city, for all the money from rentals goes to the city government.
Paris is not alone in its attempt to profit from the power of the bicycles.
Across the globe, cities such as Barcelona, which stated its bike-share program in March with 1,500 vehicles and 100 stations, and New York, which launched a five-day trial program last month, are using bicycles as a way to cut back on both traffic and pollution.
However, it remains to be seen whether people’s acceptance of these programs is simply a passing fashion or whether this movement has the power to take root and transform the face of public transportation around the world.
1.The real purpose of Vélib is________.
A.to help people save money and space
B.to make some money for the city government
C.to provide convenience to both Parisians and tourists
D.to reduce traffic and pollution in the city
2.Which of the following is TRUE according to the passage?
A.There will be 700 stations in one year’s time .
B.There will be over 20, 000 bikes in use in a year.
C.In the first two weeks there were nearly a million rentals.
D.There will be 200, 000 regular rentals each day by year end.
3.We can know from the passage that_________.
A.other cities also have such programs
B.Parisians can use the bicycles free of charge
C.Paris sets an example to many other cities
D.Paris is the first city to start such a program
4.As to the future of the program，the author is_________.
A.critical B.optimistic C.uncertain D.negative
