As we know， many people favor the idea that the college life is free and comfortable， but I’d like to say it’s not true。 As a matter of fact， my life in university is so busy that I wonder if my energy is enough。 As to my college life， I divide it into four parts， including study， student activities， library and the others。
我们知道，很多人认为大学生活是自由、舒适的，但我想说这不是真的。事实上，我的大学生活是如此的忙碌，以至于我都不知道我的能量是否足够。至于我的大学生活，我把它分为四个部分，包括学习，学生活动，图书馆和其他的。
The world is enveloped in moonlight. A poetic feeling arises and softness pervades the atmosphere. At this time, a breeze of ten accompanies the silvery light of the moon and gives the world a peculiar appearance and the people a peculiar feeling. The air is suffused with a sweet scent, driving away the ugliness and squal or of the daytime, soothing the distressed and wretched souls. If
you sing a song, your voice will reach the clouds. If you read a poem, it will echo in the mountains and valleys far away. If you hum a lullaby, its rhythm will send the whole sleepless city to dreams.
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。

第一步：四级精彩套句展示
It is universally acknowledged that + 句子(全世界都知道)
这是一个在四级作文里面用来阐述观点的经典句型，用词也很出色。
It is universally acknowledged that trees are indispensable to us.全世界都知道树木对我们是不可或缺的。
It isthat + 句子构成强调句型(The Emphatic Pattern)
英语常用的强调结构是It is/was+被强调部分(主语、宾语或状语)+ who(that)。一般说来，被强调部分指人时，用who;指事物时，用that;在美国英语中指事物时常用which来代替that。
与之类似的常用句型还有：
It is conceivable that + 句子(可想而知的)
It is obvious that + 句子(明显的)
It is apparent that + 句子(显然的)
It is conceivable that knowledge plays an important role in our life.可想而知，知识在我们的一生中扮演一个重要的角色。

It can be noticed that there are some unhealthy living habits among young people, especially college students. Typical examples include staying up late, being addicted to games, consuming in an inappropriate way. Thus, due attention should be paid to students’ daily habits.
Apparently, these bad habits may generate negative impacts. To begin with, they may impair students’ physical health and psychological fitness. In addition, what worries many teachers is that they may also exert negative influences on students’ academic performance. To conclude, never can we turn a blind eye to these phenomena.
In view of the seriousness of this issue, it is time that we took effective measure. Firstly, it is suggested that universities or colleges should cultivate students’ awareness of healthy living. Secondly, students themselves are well-advised to learn to regulate and control their own life appropriately. Only by doing so, can we hope to see the ideal scenes in which students enjoy their colorful and healthy life in Ivory Tower.
Views on donating blood vary from person to person. Some people think that it is glorious to donate blood. They hold this view because the blood they have donated can be used to save the patients who are in urgent need of it. But others hold that it is foolish for people to donate blood. In their opinion, blood is very precious to one’s health and if one loses 200ml or more of blood, it will do harm to his or her health.
As for me, I agree to the first opinion. The reasons for my choice are as follows. First, while it is true that loss of too much blood is dangerous to one’s health, it doesn’t mean donating a little blood is also harmful. Doctors tell us that donating a little blood is of no harm to anyone in good health and blood plays an indispensable role in saving a seriously ill patient.
In a word, I am convinced that donating blood is glorious. As new-century college students, we are supposed to donate blood as long as our health permits. Nothing can make us happier than saving a person.
In recent years, more and more college students quit school ahead of schedule.Except the minority quitting for objective reasons like health problem,most students leave with the pursuit of an ideal career, as well as more experience and fortune.Several factors may contribute to its emergence.
In the first place, some students think that the opportunity cost of spending four years on college campus is too high,and the job market competition is getting fiercer.
Therefore, when there’s a satisfying job available, it’s worth quitting.In the second place, some hold that the real world is a better school for them to get practical knowledge than traditional schools.
Last but not least, the publicizing and popularity of some successful businessmen like Bill Gates and Steve Jobs,who didn’t finish school but ended up with a great fortune and achievement,set examples for the young generation emphasizing individuality and personality.
However, I don’t think it’s rational for college students to quit school.Armed with high education and more mature personality, better-prepared graduates can fight for their future more easily.
In a word, college education pays off.
