海水盐度如果我们分析海水的盐度，会发现地区间只有轻微的变化，然而有些小的变化是重要的。

导致海洋的盐度变化的基本过程有三个，其中之一是通过蒸发的方式即把液态水转化为水蒸气来减少海洋中的水分。

这样由于盐留了下来，所以盐度增大。

当然，如果这种方式走向极端，将会余下白色的盐晶体。与蒸发相反的是降水，如降雨，由此水被加入海中，海水被稀释，从而盐度降低。

这种情形会发生在大量降雨的地区，或江河入海岸处。因此，盐度通过蒸发减少水分而上升或通过降水或径流增加淡水成分而下降。一般来说，在阳光很

强烈的热带地区，海水的盐度略高于世界上其它没有热带那样多的蒸发的地区。同理，在江河稀释海水的海岸地带，海水盐度略低于其它海区。

第三个可以变更盐度的过程与海洋中冰的形成和融化有关。海水冻结时，溶于其中的物质被留了下来。这样，在新形成的海

水冰面的正下方的海水比在冰形成之前有更高的盐度。

当然，当冰融化的时候，会降低周围水中的盐度。

在南极洲边缘的威德尔海中，结冰过程增加低温海水的盐度，从而形成了浓度最大的海水。这些大密度的海水下沉，可以在世界海洋的深水域发现。

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 etreme, of course, white crystals of salt would be left behind.

the opposite of evaporation is precipitation, such as rain, by which water is added to the ocean. here the ocean is being diluted 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 sea water is frozen, the dissolved materials are left behind. in this manner, sea water directly materials are left behind.

in this manner, sea water 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 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.

Computers have played an important part in our life. They can do most of the things people can do. Through computers, we can acquire knowledge and get the latest news. Computers have made the communication with our friends convenient and easy.But some young people are so interested in playing games on line that they even drop out of school. It is not the computers fault.It depends on the users. We should make good use of computers.

Directions: For this part, you are allowed 30 minutes to write a short essay entitled Goal Setting Is Important by commenting on John Ruskins famous remark, Living without an aim is like sailing without a compass. You should write at least 120 words but no more than 180 words.

【范文】Goal Setting Is Important

Living without an aim is like sailing without a compass. This philosophical wisdom by John Ruskin, one of the greatest British writers, tells us that goal setting is extremely important in life.

Why is goal setting so important? The main importance of goal setting is that it provides us with direction and purpose. When we have goals, we know what we want to achieve so that we can focus our mindson a single worthwhile target and avoid getting distracted easily. Personal goal setting also provides us with motivation to achieve what we want to achieve.

Goal setting is of especial significance for todays students. A study reveals that when students set goals, they learn the importance of taking responsibility, of minimizing excuses and of helping others. Goal setting is a lifelong skill that first helps students succeed in school and then later in life.

Theres No Story without Coincidence

The story happened a year ago. One day, I was walking along the street when an old man walked towards me. He asked me the way in English. No matter how hard I tried I couldnt understand what he said. He repeated again and again. At last I seemed to know what he was saying.

He was a Japanese. He thought I could speak English. So he asked me the way in English. My goodness! His Japanese English confused me a lot. then he spoke English very slowly.He even wrote the English words on a piece of paper. In the end I managed to help him get the right way. I thought maybe it was necessary for me to learn some Japanese.

A few months later, I was enrolled to attend a summer course, learning Japanese. I was surprised to find that old man was there, teaching us Japanese.Theres no story without coincidence!

When I was a small child, I usually thought it was a good luck to be sick in bed. You see, when you are ill, you can stay home. There is no need to finish so much homework. Your parents will take care of you. Besides there is always something good to eat. Isnt it enjoyable to eat so much nice food?

A week ago, I was really in hospital. It was painful for me to stay in bed for several days. I couldnt get up. I couldnt even move. I didnt want to eat anything though there was a lot before me. I missed my classmates and teachers so much that I was anxious to get back to meet my friends. I was also worried about my final examination.

Now I have grown up. I have changed my mind.

我们大家都知道，我们人类生存唯一的地方就是地球，可是大家知道吗？地球上最珍贵的资源就是水资源，而且地球上有70%都是被水所包围的。假如人类没有了水资源，大概离灭绝也就不远了。

水是人类生活中所必须要的一件珍贵资源。举个简单的例子来讲，我们每天吃饭要用水，每天要喝水，洗衣服要用水，植物的生长也需要水，人类吃的粮食也需要水，等等这些。如果水没有满足人们这些基本的生活条件，那么人类的生活将会是怎样，可想而知。

人体内有60%是水，水对于人身体的重要性不言而喻，我们人的血液就是包含大量的水份，一旦人发生脱水的现象，就会濒临死亡。所以科学家规定出每人每天必须保证摄入2500毫升的水，才能保证人体的正常生理代谢。所以说水对于人活着是很重要的。

当然种植物也需要水，其中与人类息息相关的，那就是人类的粮食。像土地里面种植的小麦，玉米，大豆，高粱，水稻，这些农作物都离不开水的灌溉，没有水，它们就不会生长，就不会长出粮食，这样的话，人类没有粮食食用，那还能活吗？

水是生命的源泉，万物的生长，世间的运作，都需要水资源的参与。那既然水资源如此的重要，我们为何还不珍惜水资源呢？我们经常看到生活中有的人浪费水，比如：出门不关紧水龙头、矿泉水喝一半就扔掉、以及水资源的单次浪费利用…虽然我们现在生活中还有谁可以利用，可是我们经常可以听到新闻中的报道，非洲地区有许许多多用不上水的人们，假如我们每个人每天都能节约一点水，那么就能帮助他们过上好一点的生活，甚至挽救一条生命。

水资源如此重要，保护水资源已经到了迫在眉睫的地步，保护水资源是需要每个人去做出努力的，换句话说，保护水资源就是保护人类自己。
