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 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.
Notes：
salinity n.盐度 ②conversion n.转化 ③dilute vt.淡化
【语篇解读】 本文是说明文。全文首先说明了为什么海水的含盐量很高，接着又说明了世界各地海水的含盐量是不一样的，例如降雨量小的地方含盐量高，而降雨量大的地方含盐量低。海水的含盐量也与海水的蒸发量以及结冰程度有关。
1. What does the underlined word in the first paragraph mean?
A.Escape. B.Decrease. C.Pollution. D.Increase.
答案 B [猜测词义题。由画线词语所在句子可知，“evaluation”与画线词语的意义相关，蒸发后海水量一定会“减少”。]
2.Generally speaking，where has the higher salinity in the world?
A.The tropical regions. B.The polar region.
C.The temperate zone. D.The frigid zone.
答案 A [细节理解题。由第三段第一句“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.”可知，通常热带地区的海水盐度较高，因为那里海水的蒸发量大。]
3.Which of the following statements is RIGHT?
A.The salinity of ocean waters is the same from place to place.
B.If the change of the salinity of ocean waters is small，it always doesn't matter.
C.Rain can lower the salinity of ocean waters.
D.When the sea ice is formed，the salinity of ocean waters is lower.
答案 C [细节理解题。由第二段第一句“The opposite of evaporation is precipitation，such as rain，by which water is added to the ocean.”可知，雨水可以降低海水的盐度。]
4.Which of the following can be the best title for this passage?
A.Ocean Waters
B.The Changeable Ocean Waters
C.How to analyze the Salinity of Ocean Waters
D.The Salinity of Ocean Waters
答案 B [主旨大意题。文章主要介绍了影响海水盐度的三种因素：蒸发、稀释以及冰山的形成和消融。]
