　　四级阅读专项训练题1

　　At the close of each business day, most trained teachers, administrators, politicians, and statesmen make objective analyses of all that has transpired. They then carefully evaluate performance in the achievement of certain specified objectives. You, as a student, would be wise to adopt the same practice and reflect upon your performance in relating to the achievement of certain personal and educational objectives.

　　First, what was your purpose, your motivational force in seeking an education? Did you seek an education in active performance, or did you seek to be educated in passive reception and automatic acquisition(获取) of information that was fed to you? Was the profit motive your primary motivation for obtaining an education? Do you want a better education for the sole purpose of getting a better job? What does the educational process really mean to you?

　　We are part of a world in which men thrill to the touch of gold and hearts respond to the word money instead of being thrilled by the thought of good. We five in a world in which we are taught that the pursuit of happiness is an equation for the most rapid acquisition of money, by whatever means.

　　If profit and money are your first priorities, and compassion and commitment to people your least concern, you have done little other than accumulate some facts and compile some information for future reference. If making money is your daydream and losing money your nightmare, if poverty is your worst fear and making money your most fervent prayer, you have missed the opportunity for education. You have failed yourself and have only received Nome instruction.

　　When we analyze the salt salinity(盐浓度) of ocean waters, we find that it varies 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. In this manner, the salinity is increased, since the salt stays behind. If this is carried to the extreme, of course, white salt would be left behind; this, by the way, is how much of the table salt we use is actually obtained.

　　The opposite of evaporation is precipitation, 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.

　　Normally, in hot 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, the densest water in the ocean 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 portion of the oceans of the world.
