高中英语作文是我们学习中的一大重点，写作文并不是一件简单轻松的事。也希望自己写做的作文言简意赅？《海洋水盐优秀英语作文（精选）》这篇文章应该会给你一个满意的答案！
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.

故事前言 The Introduction of Stories 精选优秀英语作文
Before we read the books, the introduction will be showed ahead of the stories’ beginning. At first, I get used to the introduction and have the main idea of the stories. But later, as I read more books, I find the introduction is not a good way to help readers to appreciate the charm of the stories. Usually, the readers will get the main idea before they read the stories, because some introduction is very specific, even the ending of the story is being told, so readers will not feel excited and surprised in the process of reading. While if they haven't read the introduction, then every detail of the story will attract them, because they have no idea what will happen in the next chapter. So I advise not to read the introduction, and the unknown plot is full of attraction.
在看书之前，在故事开始的前都会有简介。起初，我习惯了先看故事简介，对故事有个大概的了解。但是后来，在我读的书越来越多后，我发现先看简介并不是对读者来说并不是最好的方式去欣赏故事的魅力。通常，读者会在读故事之前就对故事有所了解，因为有些介绍是非常具体的，故事的结局也已经得知了，所以读者在阅读的过程中不会感到兴奋和惊喜。而如果他们没有看过简介，故事的每个细节都会吸引他们，因为他们不知道在下一章中会发生什么。所以我建议不要读先看简介，未知的情节充满了吸引力。
