1、高中英文范文大全 高中英文自我介绍范文高中教育在学制体系中位置特殊,对人一生的教育有着极其重要的影响。下面是WTT给大家整理的高中英文范文,供大家参阅!高中英文范文:TelevisionsTelevision-the most pervasive and persuasive of modern technologies, marked by rapid change and growth-is moving into a new era, an era of extraordinary sophistication and versatility, which promises to res
2、hape our lives and our world. It is an electronic revolution of sorts, made possible by the marriage of television and puter technologies.The word “television”, derived from its Greek (tele: distant) and Latin (visio: sight) roots, can literally be interpreted as sight from a distance. Very simply p
3、ut, it works in this way: through a sophisticated system of electronics, television provides the capability of converting an image (focused on a special photoconductive plate within a camera) into electronic impulses, which can be sent through a wire or cable. These impulses, when fed into a receive
4、r (television set), can then be electronically reconstituted into that same image.Television is more than just an electronic system, however. It is a means of expression, as well as a vehicle for munication, and as such bees a powerful tool for reaching other human beings.The field of television can
5、 be divided into two categories determined by its means of transmission. First, there is broadcast television, which reaches the masses through broad-based airwave transmission of television signals. Second, there is nonbroadcast television, which provides for the needs of individuals or specific in
6、terest groups through controlled transmission techniques.Traditionally, television has been a medium of the masses. We are most familiar with broadcast television because it has been with us for about thirty-seven years in a form similar to what exists today. During those years, it has been controll
7、ed, for the most part, by the broadcast works, ABC, NBC, and CBS, who have been the major purveyors of news, information, and entertainment. These giants of broadcasting have actually shaped not only television but our perception of it as well. We have e to look upon the picture tube as a source of
8、entertainment, placing our role in this dynamic medium as the passive viewer.高中英文范文:The Beginning of DramaThere are many theories about the beginning of drama in ancient Greece. The on most widely accepted today is based on the assumption that drama evolved from ritual. The argument for this view go
9、es as follows. In the beginning, human beings viewed the natural forces of the world-even the seasonal changes-as unpredictable, and they sought through various means to control these unknown and feared powers. Those measures which appeared to bring the desired results were then retained and repeate
10、d until they hardened into fixed rituals. Eventually stories arose which explained or veiled the mysteries of the rites. As time passed some rituals were abandoned, but the stories, later called myths, persisted and provided material for art and drama.Those who believe that drama evolved out of ritu
11、al also argue that those rites contained the seed of theater because music, dance, masks, and costumes were almost always used, furthermore, a suitable site had to be provided for performances and when the entire munity did not participate, a clear division was usually made between the “acting area”
12、 and the “auditorium.” In addition, there were performers, and, since considerable importance was attached to avoiding mistakes in the enactment of rites, religious leaders usually assumed that task. Wearing masks and costumes, they often impersonated other people, animals, or supernatural beings, a
13、nd mimed the desired effect-success in hunt or battle, the ing rain, the revival of the Sun-as an actor might. Eventually such dramatic representations were separated from religious activities.Another theory traces the theaters origin from the human interest in storytelling. According to this vies t
14、ales (about the hunt, war, or other feats) are gradually elaborated, at first through the use of impersonation, action, and dialogue by a narrator and then through the assumption of each of the roles by a different person. A closely related theory traces theater to those dances that are primarily rh
15、ythmical and gymnastic or that are imitations of animal movements and sounds.高中英文范文:ElectricityThe modern age is an age of electricity. People are so used to electric lights, radio, televisions, and telephones that it is hard to imagine what life would be like without them. When there is a power fai
16、lure, people grope about in flickering candlelight, cars hesitate in the streets because there are no traffic lights to guide them, and food spoils in silent refrigerators.Yet, people began to understand how electricity works only a little more than two centuries ago. Nature has apparently been expe
17、rimenting in this field for million of years. Scientists are discovering more and more that the living world may hold many interesting secrets of electricity that could benefit humanity.All living cell send out tiny pulses of electricity. As the heart beats, it sends out pulses of record; they form
18、an electrocardiogram, which a doctor can study to determine how well the heart is working. The brain, too, sends out brain waves of electricity, which can be recorded in an electroencephalogram. The electric currents generated by most living cells are extremely small - often so small that sensitive
19、instruments are needed to record them. But in some animals, certain muscle cells have bee so specialized as electrical generators that they do not work as muscle cells at all. When large numbers of these cell are linked together, the effects can be astonishing.The electric eel is an amazing storage
20、battery. It can seed a jolt of as much as eight hundred volts of electricity through the water in which it live. (An electric house current is only one hundred twenty volts.) As many as four-fifths of all the cells in the electric eels body are specialized for generating electricity, and the strength of the shock it can deliver corresponds roughly to length of its body.以上是WTT整理所得,欢迎大家阅读和收藏。第 7 页 共 7 页
