英语小短文 The source of Energy
作者:英语短文
The source of Energy A summary of the physical and chemical nature of life must begin, not on the Earth, but in the Sun; in fact, at the Sun's very center. It is here that is to be found the source of the energy that the Sun constantly pours out into space as light and heat. This energy is librated at the center of the Sun as billions upon billions of nuclei of hydrogen atoms collide with each other and fuse together to form nuclei of helium, and in doing so, release some of the energy that is stored in the nuclei of atoms. The output of light and heat of the Sun requires that some 600 million tons of hydrogen be converted into helium in the Sun every second. This the Sun has been doing for several thousands of millions of year. The nuclear energy is released at the Sun's center as high-energy gamma radiation, a form of electromagnetic radiation like light and radio waves, only of very much shorter wavelength. This gamma radiation is absorbed by atoms inside the Sun to be reemitted at slightly longer wavelengths. This radiation , in its turn is absorbed and reemitted. As the energy filters through the layers of the solar interior, it passes through the X-ray part of the spectrum eventually becoming light. At this stage, it has reached what we call the solar surface, and can escape into space without being absorbed further by solar atoms. A very small fraction of the Sun's light and heat is emitted in such directions that after passing unhindered through interplanetary space, it hits the Earth.
英语短文 Folk Cultures
作者:英语短文
Folk Cultures A folk culture is a small isolated, cohesive, conservative, nearly self-sufficient group that is homogeneous in custom and race with a strong family or clan structure and highly developed rituals. Order is maintained through sanctions based in the religion or family and interpersonal. Relationships are strong. Tradition is paramount, and change comes infrequently and slowly. There is relatively little division of labor into specialized duties. Rather, each person is expected to perform a great variety of tasks, though duties may differ between the sexes. Most goods are handmade and subsistence economy prevails. Individualism is weakly developed in folk cultures as are social classes. Unaltered folk cultures no longer exist in industrialized countries such as the United States and Canada. Perhaps the nearest modern equivalent in Anglo America is the Amish, a German American farming sect that largely renounces the products and labor saving devices of the industrial age. In Amish areas, horse drawn buggies still serve as a local transportation device and the faithful are not permitted to own automobiles. The Amish's central religious concept of Demut "humility", clearly reflects the weakness of individualism and social class so typical of folk cultures and there is a corresponding strength of Amish group identity. Rarely do the Amish marry outside their sect. The religion, a variety of the Mennonite faith, provides the principal mechanism for maintaining order. By contrast a popular culture is a large heterogeneous group often highly individualistic and a pronounced many specialized professions. Secular institutions of control such as the police and army take the place of religion and family in maintaining order, and a money-based economy prevails. Because of these contrasts, "popular" may be viewed as clearly different from "folk". The popular is replacing the folk in industrialized countries and in many developing nations. Folk-made objects give way to their popular equivalent, usually because the popular item is more quickly
or cheaply produced, is easier or time saving to use or leads more prestige to the owner.
大学英语作文范文 My first Job
作者:英语
My first Job Before I started at university,I took my first job as a waitress in a nice restaurant.At the night before my first day.I was too excited to go to sleep and as a result,I got up late in the morning.I threw on my clothes and rushed over to the restaurant. In a great hurry,I didn't hear clearly the head waiter's instruction that we should go into the kitchen through one door and out from the other.So when I took two plates of eggs and bacon and an orange juice out to the restaurant,I went straight towards the wrong door and collided with another waiter coming in! Worst of all was that I wore a pair of smart shoes but with high heels! A few hours later I was in agony yet had no time to change them. By the time we finished serving dinner at about 10:30 I was completely exhausted. Nevertheless, I learnt something through my experience.
英语作文范文 Fighting Criminals
作者:英语
Fighting Criminals Today the crime rate in soe cities of our country is rising. Many citizens often complain about the thefts and robberies that have taken palce in the areas they live in and appeal to the governments at all levels to take effective measures to reduce the crime rate. Faced with criminals,some people are so frightened that they shamelessly give up the fight and other people turn a blind eye to them.However,some people are brave enough,to risk their lives to fight the criminals.Their fearless actions prevented the criminals from doing evils,saved the victims,and protected the public properties. To reduce the crime rate,we all the people should first receive a law education.Criminals must be severely punished.Meanwhile we should set up a foundation to reward those who fight criminals.It is also important to call on people to learn from those heroes and encourage more people to stand up to crime. Private car Outline:
  1)Advantages of owning a private car.
  2)Disadvantages of owning a private car.
  3)Should it be necessary to enlarge the private car market? Why or why not? Nowadays, any Chinese can enjoy the luxury of owning a private car - if he or she can afford it. Having a car of your own means no more traveling to work on crowded buses or subway trains, and you can drop off the children at school on the way. Moreover, it also means that you can enjoy the weekends and holidays better, because with a car you can go to places where the regular buses and trains do not go, and so you can find a quiet scenic spot with no crowds.
However, there are drawbacks to owning a car. For one thing, with the increase in car ownership in recent years, the roads are becoming more and more crowded, often making the journey to work more of a nightmare than a dream. For another, it is not cheap to run a car, as the prices of gasoline and repairs are constantly rising, not to mention the prices you have to pay for a licence and insurance coverage. Having considered both sides of the argument, I have come to the conclusion that the advantages of owning a car outweigh the disadvantages. Therefore, it seems to me that China should increase its output of automobiles and enlarge the private car market. The result would be that cars would become cheaper, while at the same time the extra demand would encourage the auto industry to produce more efficient and family-oriented vehicles.
