介绍庆亏槐大学生活的英语短文篇一
Time spent at a university is a most worthwhile period in a young person's life. This is a time when a student begins to form his or her ideas about life in general. Attending classes and studying in the library keep a student busy and provide him or her with access to valuable information， adding to his or her knowledge base.
Campus life can also be rich and colorful. Most universities offer a variety of extracurricular activities such as sports events， contests， and other social gatherings， enabling the students to experience relief from study and homework. Students often form lifelong friendships through the varied experiences of university life.
During the time a student spends at university， he not only develops his intellectual abilites，he also develops social skills as well as knowledge and wisdom necessary for choosing a future career. By learning how to balance intense study and recreation， a student will be well prepared for the challenges of future responsibilities.
介绍大学生活的英语短文篇二
It has been two years since I first got to university. Some of my clas*ates say that the college life is boring, because they have plenty of time but do not know what to do. However, from my point of view, the campus life in college is interesting and colorful as long as you make it meaningful.
距我第一次去上大学已经两年了。我有的同学说大学生活很无誉友聊，因为他们有很多时间却不知道做什么。但是，在我看来，只要你把它变得有意义，大学校园生活是有趣且丰富多彩的。
空亮 In the first semester in college, I didn't relax and I still worked hard as I was in the senior school. I usually spent two hours in study at night and I went to the classroom forautonomous learning.But the difference is that I have many extracurricular activities. For example, I went to the English Corner regularly on Tuesday night, in which I could practice my spoken English and make friends with common interests.
大学第一个学期，我没有放松，仍然像在高中一样努力学习。晚上我经常花两个小时学习，我会到教室自习。但是不同的是我有很多课外活动。比如，我每周二晚上都去英语角，在那我可以练习我的口语，和有共同兴趣的人交朋友。
Besides, I join the Student Union of my department. In the Student Union, I have a group of workmates who work hard together and support to each other. Actually, it looks like a big, warm family that we can share our lives together. During various activities, I realize the importance of team spirit that helps us go further.
此外，我参加了系里的学生会。在学生会里，我有一群同事，我们一起努力工作并且互相支持。在各种各样的活动中我意识到 团队精神 的重要性，它能帮助我们走得更远。
Finally, college is great stage to improve a student and show one's abilities. In college, I know more about our society and get more channels to explore the outside world. I realize that I am not only a student but also an * who is preparing to step into the society.
最后，大学是提高学生和展现一个人能力的大舞台。在大学里，我对社会有了更多的认识，同时获得了更多探索外面世界的 渠道 。我意识到我不仅是一个学生也是一个即将踏入社会的成年人。
In short, I cherish my life in college campus and I will try hard to make it colorful as well as meaningful.
总之，我珍惜 我的大学 校园生活，而且我会努力使之丰富且富有意义。

Hello everyone.Today I'm glad to be here to give a speech about my fresh experience in China Agriculture University.
大家好。今天我很高兴能在这里做一个关于我在 中国农业大学 首次经历的讲话。
First I must say the campus life is really different from what I have experienced in high school.For instance,I used to lean upon my dormitory teacher to wake me up on time.But now I have to set several alarm clocks to make myself could hear them in the morning otherwise I would miss my class.And then even worse there would be nobody remind me except my teacher!So the differences are everywhere and I could easily find them.The change of life is great and it's wonderful:I have more time of my own and the rights to decide how I live.
我要说的第一件事是大学校园生活真的不同于我所经历过的高中。例如，我过去常常依靠宿舍老师来按时叫醒我。但现在我必须设几个闹钟才能让我在早上听到闹钟响，否则我会错过我的课。然后更糟糕的是除了我的老师没有人会提醒我!所以不同到处都是，我可以很轻易地就找到不同之处。生活的变化很大，它也很美妙：我有更多我自己的时间和决定生活方式的权利。
My campus activities are rich and colorful.Learning English has become a habit to me cause I plan to study abroad in next few years.Playing Guzheng is my favorite activity.I have kept on practising it since I was a little girl and I wish to win more competitions in my campus life.
我的大学校园活动是丰富多彩的。 学习英语 已经成为我的习惯，因为我计划在几年后 出国 留学 。古筝是我最喜欢的活动。我还是个小女孩时，我一直在练习古筝，我希望在我的大学校园生活期间赢得更多的比赛。
Our university has the first level equipments and the most experienced teachers,also has the best students(laugh).I consider it to be a honor that I've got a chance to study here and I sincerely hope that we could live wonderful lives in our campus!
我们大学有一流的设备和最有 经验 的教师，也有最好的学生(大笑)。我认为我有机会在这里学习是一种荣誉，我真诚地希望我们能在我们的大学中活得更精彩!

What is Hydraulic?
A complete hydraulic system consists of five parts, namely, power components, the implementation of components, control components, no parts and hydraulic oil. The role of dynamic components of the original motive fluid into mechanical energy to the pressure that the hydraulic system of pumps, it is to power the entire hydraulic system. The structure of the form of hydraulic pump gears are generally pump, vane pump and piston pump. Implementation of components (such as hydraulic cylinders and hydraulic motors) which is the pressure of the liquid can be converted to mechanical energy to drive the load for a straight line reciprocating movement or rotational movement. Control components (that is, the various hydraulic valves) in the hydraulic system to control and regulate the pressure of liquid, flow rate and direction. According to the different control functions, hydraulic valves can be divided into the village of force control valve, flow control valves and directional control valve. Pressure control valves are divided into benefits flow valve (safety valve), pressure relief valve, sequence valve, pressure relays, etc.; flow control valves including throttle, adjusting the valves, flow diversion valve sets, etc.; directional control valve includes a one-way valve , one-way fluid control valve, shuttle valve, valve and so on. Under the control of different ways, can be divided into the hydraulic valve control switch valve, control valve and set the value of the ratio control valve. Auxiliary components, including fuel tanks, oil filters, tubing and pipe joints, seals, pressure gauge, oil level, such as oil dollars. Hydraulic oil in the hydraulic system is the work of the energy transfer medium, there are a variety of mineral oil, emulsion oil hydraulic molding Hop categories.
Hydraulic principle
It consists of two cylinders of different sizes and composition of fluid in the fluid full of water or oil. Water is called "hydraulic press"; the said oil-filled "hydraulic machine." Each of the two liquid a sliding piston, if the increase in the *all piston on the pressure of a certain value, according to Pascal's law, *all piston to the pressure of the pressure through the liquid passed to the large piston, piston top will go a long way to go. Based cross-sectional area of the *all piston is S1, plus a *all piston in the downward pressure on the F1. Thus, a *all piston on the liquid pressure to P = F1/SI,Can be the same size in all directions to the tran*ission of liquid. "By the large piston is also equivalent to the inevitable pressure P. If the large piston is the cross-sectional area S2, the pressure P on the piston in the upward pressure generated F2 = PxS2 Cross-sectional area is a *all multiple of the piston cross-sectional area. From the type known to add in a *all piston of a *aller force, the piston will be in great force, for which the hydraulic machine used to suppress plywood, oil, extract heavy objects, such as forging steel.
History of the development of hydraulic
And air pressure drive hydraulic fluid as the tran*ission is made according to the 17th century, Pascal's principle of hydrostatic pressure to drive the development of an emerging technology, the United Kingdom in 1795 Joseph (Joseph Braman ,1749-1814), in London water as a medium to form hydraulic press used in industry, the birth of the world's first hydraulic press. Media work in 1905 will be replaced by oil-water and further improved.
World War I (1914-1918) after the extensive application of hydraulic tran*ission, especially after 1920, more rapid development. Hydraulic components in the late 19th century about the early 20th century, 20 years, only started to enter the formal phase of industrial production. 1925 Vickers (F. Vikers) the invention of the pressure balanced vane pump, hydraulic components for the modern industrial or hydraulic tran*ission of the gradual establishment of the foundation. The early 20th century Constantine (G • Constantimsco) fluctuations of the energy carried out by passing theoretical and practical research; in 1910 on the hydraulic tran*ission (hydraulic coupling, hydraulic torque converter, etc.) contributions, so that these two areas of development.
The Second World War (1941-1945) period, in the United States 30% of machine tool applications in the hydraulic tran*ission. It should be noted that the development of hydraulic tran*ission in Japan than Europe and the United States and other countries for nearly 20 years later. Before and after in 1955, the rapid development of Japan's hydraulic drive, set up in 1956, "Hydraulic Industry." Nearly 20 to 30 years, the development of Japan's fast hydraulic tran*ission, a world leader.
Hydraulic tran*ission There are many outstanding advantages, it is widely used, such as general workers. Plastic processing industry, machinery, pressure machinery, machine tools, etc.; operating machinery engineering machinery, construction machinery, agricultural machinery, automobiles, etc.; iron and steel industry metallurgical machinery, lifting equipment, such as roller adjustment device; civil water projects with flood control the dam gates and devices, bed lifts installations, bridges and other manipulation of institutions; speed turbine power plant installations, nuclear power plants, etc.; ship deck crane (winch), the bow doors, bulkhead valves, such as the stern thruster ; special antenna technology giant with control devices, measurement buoys, movements such as rotating stage; military-industrial control devices used in artillery, ship anti-rolling devices, aircraft simulation, aircraft retractable landing gear and rudder control devices and other devices.

Under the control of different ways, can be divided into the hydraulic valve control switch valve, control valve and set the value of the ratio control valve. Auxiliary components, including fuel tanks, oil filters, tubing and pipe joints, seals, pressure gauge, oil level, such as oil dollars. Hydraulic oil in the hydraulic system is the work of the energy transfer medium, there are a variety of mineral oil, emulsion oil hydraulic molding Hop categories.
Hydraulic principle
It consists of two cylinders of different sizes and composition of fluid in the fluid full of water or oil. Water is called "hydraulic press"; the said oil-filled "hydraulic machine." Each of the two liquid a sliding piston, if the increase in the *all piston on the pressure of a certain value, according to Pascal's law, *all piston to the pressure of the pressure through the liquid passed to the large piston, piston top will go a long way to go. Based cross-sectional area of the *all piston is S1, plus a *all piston in the downward pressure on the F1. Thus, a *all piston on the liquid pressure to P = F1/SI,Can be the same size in all directions to the tran*ission of liquid. "By the large piston is also equivalent to the inevitable pressure P. If the large piston is the cross-sectional area S2, the pressure P on the piston in the upward pressure generated F2 = PxS2 Cross-sectional area is a *all multiple of the piston cross-sectional area. From the type known to add in a *all piston of a *aller force, the piston will be in great force, for which the hydraulic machine used to suppress plywood, oil, extract heavy objects, such as forging steel.
History of the development of hydraulic
And air pressure drive hydraulic fluid as the tran*ission is made according to the 17th century, Pascal's principle of hydrostatic pressure to drive the development of an emerging technology, the United Kingdom in 1795 Joseph (Joseph Braman ,1749-1814), in London water as a medium to form hydraulic press used in industry, the birth of the world's first hydraulic press. Media work in 1905 will be replaced by oil-water and further improved.
World War I (1914-1918) after the extensive application of hydraulic tran*ission, especially after 1920, more rapid development. Hydraulic components in the late 19th century about the early 20th century, 20 years, only started to enter the formal phase of industrial production. 1925 Vickers (F. Vikers) the invention of the pressure balanced vane pump, hydraulic components for the modern industrial or hydraulic tran*ission of the gradual establishment of the foundation. The early 20th century Constantine (G • Constantimsco) fluctuations of the energy carried out by passing theoretical and practical research; in 1910 on the hydraulic tran*ission (hydraulic coupling, hydraulic torque converter, etc.) contributions, so that these two areas of development.
The Second World War (1941-1945) period, in the United States 30% of machine tool applications in the hydraulic tran*ission. It should be noted that the development of hydraulic tran*ission in Japan than Europe and the United States and other countries for nearly 20 years later. Before and after in 1955, the rapid development of Japan's hydraulic drive, set up in 1956, "Hydraulic Industry." Nearly 20 to 30 years, the development of Japan's fast hydraulic tran*ission, a world leader.
Hydraulic tran*ission There are many outstanding advantages, it is widely used, such as general workers. Plastic processing industry, machinery, pressure machinery, machine tools, etc.; operating machinery engineering machinery, construction machinery, agricultural machinery, automobiles, etc.; iron and steel industry metallurgical machinery, lifting equipment, such as roller adjustment device; civil water projects with flood control the dam gates and devices, bed lifts installations, bridges and other manipulation of institutions; speed turbine power plant installations, nuclear power plants, etc.; ship deck crane (winch), the bow doors, bulkhead valves, such as the stern thruster ; special antenna technology giant with control devices, measurement buoys, movements such as rotating stage; military-industrial control devices used in artillery, ship anti-rolling devices, aircraft simulation, aircraft retractable landing gear and rudder control devices and other devices.
A complete hydraulic system consists of five parts, namely, power components, the implementation of components, control components, no parts and hydraulic oil. The role of dynamic components of the original motive fluid into mechanical energy to the pressure that the hydraulic system of pumps, it is to power the entire hydraulic system. The structure of the form of hydraulic pump gears are generally pump, vane pump and piston pump. Implementation of components (such as hydraulic cylinders and hydraulic motors) which is the pressure of the liquid can be converted to mechanical energy to drive the load for a straight line reciprocating movement or rotational movement. Control components (that is, the various hydraulic valves) in the hydraulic system to control and regulate the pressure of liquid, flow rate and direction. According to the different control functions, hydraulic valves can be divided into the village of force control valve, flow control valves and directional control valve. Pressure control valves are divided into benefits flow valve (safety valve), pressure relief valve, sequence valve, pressure relays, etc.; flow control valves including throttle, adjusting the valves, flow diversion valve sets, etc.; directional control valve includes a one-way valve , one-way fluid control valve, shuttle valve, valve and so on.
