Now， with the development of network technology， its high aging， high-capacity， multi-dimensional as well as restrictions on time-domain characteristics of students improve English reading ability provides a possible network of schools at all levels into the classroom has also become the teachers and students access to relevant reading material Modern information technology education courses and training so that students and teachers have the appropriate Relevant research data indicate that about 60% of human knowledge is acquired by Read about the importance of access to knowledge of human can be Therefore， in middle school English teaching， the majority of English teachers attach great importance to improve student reading Reading comprehension of students are in fact any expansion capabilities， background knowledge and processing strategies between the result of the To have this ability， but also must possess the necessary knowledge， experience tells us that day-to-day teaching， whether teachers or students， such as he has social， cultural， customs， astronomy， geography and history knowledge， then read the contents of information materials in English， the more do not have the knowledge in this area much easier， much more thorough understanding of the will， speed has also improved He not only be able to understand the contents of the article said， and a text also will be able to talk about the content and the text does not talk about the relevant If you do not have such knowledge， he can not achieve a thorough understanding of the Could think， reading is to expand and improve their reading capacity， knowledge， understanding the primary purpose to help students improve reading skills and language Students exist because of differences in personality， personal interests， hobbies， have a markedly different， therefore， permit the students thought health topic in the material under the premise of the characteristics of the light of their own selection of reading material Selection of reading materials mainly news， popular science knowledge categories， sports， music， fashion and other types of students more interested in the topic-oriented， including astronomy and geography， historical figures， environmental protection， natural disasters， working life， literature and art， science and technology ， sports health， humanities， politics and so In view of the network to read information on the numerous and complicated， both the network of civic education， strengthening supervision， to eliminate adverse The timeliness of the network when reading to reflect the very obvious and only news as an example: in 2001 such as the The twins towers attacked on S， 02-year US strikes on Iraq and in 2003 the Bird Flue all over the world such as reading materials in a very short period of time on dialogue with the students， and strengthen the emotional needs of English reading ability are substantial practice in reading Therefore， the reading ability required in various forms， especially the full use of network resources to provide rich Students need to develop good reading habits and good reading skills， and perseverance， Not only to fully tap their potential for rapid reading ability， and attention should be paid to improve reading skills and reading skills to eliminate Only master English reading skills of students in order to read Such a reading can not only stimulate students interest in reading and motivation to meet their sense of achievement in learning English; but also cultivate among the students found that problem， problem-solving skills and think in English， with English communicative ability and self-learning English language ability
The metric was designed to fix some of the problems found in the more popular BLEU metric， and also produce good correlation with human judgement at the sentence or segment level This differs from the BLEU metric in that BLEU seeks correlation at the corpus
The Greek Heavenly Thoughts The Greek was the first recognize the distinction between the natural and the In other words ， they found the nature， since then， the cosmology(宇宙学) could never be maintain a system of Gradually， the Greek believed themselves to live in a cosmos， and considered the cosmos to be an entirely natural Besides they saw an order in the The order， to them， not only means an arrange， but also a good order， and also a beautiful， elegant With an optimism(乐观主义)， they believed the order， and the cosmos were comprehensible(可知的)， and furthermore， could be described in words and When the Greek formed these crucial ideas， some earliest philosophers and scientists were important and The Milesians(米利都学派得的哲学家)， including Thales(泰勒斯)， Anaximander(阿纳克西曼德)， described the cosmos in entirely natural terms for the first Heraclitus(赫拉克立特) insisted that the cosmos worked according to a logos(理性)， which mean “word”， “account”， “measure”， and “proportion”， and if we grasp this logos， the cosmos could be understood and described After the Greek accepted the idea that the cosmos was a natural place and comprehensible， some pre-Socratics(前苏格拉底时代德哲学家) overcame some significant conceptual(观念上的) hurdles to achieve a more sophisticated There was the move from a hemispherical(半球形) universe to a spherical(球形) one， and a earth supported by water to supported by air， and then to one which need no In the earlier Greek cosmologies， objects were thought to drop in parallel straight lines from the top of the cosmos to the bottom， this led to the problem why the earth doesn’t fall to the bottom of the cosmos， so in this sort of the cosmos， something is required to support the Then Aristotle placed the earth at the center of the cosmos， there was no the problem of the earth He believed that objects moved to the center of the cosmos， that is the earth The idea that the earth was central and stable dominated Greek astronomy and In Greek minds， it can explain many Firstly， the experience told Greek， if one was in rapid motion， he certainly knew about it， so they thought， if the earth has a daily rotation from west to east， there should be constant wind from east to west; if the earth is in motion around the sun， all objects will sweep off the face of the Secondly， because they had no knowledge of gravity， they believe if the earth in rapid motion， it will disintegrate(解体) Thirdly， if the earth takes up different positions relative to the stars(恒星)， there should be a stellar parallax(恒星视差量)， one can detect slight changes in the apparent positions of the stars from the When the Greek physics， astronomy， philosophy and common sense all seemed to indicate an immobile earth， there was an important consequence， all of the motions of the heavens were real motions to the earth， not apparent ones due to the motion of the At the outset， Greek observational astronomy was rather divorced(背离) from philosophical speculation about the nature of the Some observed the heavens and took careful notes of what they saw， some produced cosmological models based on general philosophical But no one gave a cosmological model that were anywhere near explaining， in a precise manner， the phenomena that had been The Pythagoreans(毕达哥拉斯学派的哲学家) made the first They believed in the center of the cosmos was a fire， not the sun， the fire was shield from the earth by a body known as the counter The model was vague and speculative， and the earth moves around the fire， and between the fire and earth， there was the counter Plato(柏拉图) produced a slightly better model， had central earth， with the sun， the moon， the five planets and the stars orbiting around Then it was a basic assumption of Greek astronomy and cosmology， if some motions seems not circular or regular， almost all Greek philosophers and scientists would consider these as some combination of several circular and regular Neither of two models could account for two important phenomena relating to the point at which the sun The sun does not always set due west(正西方) Where the sun sets during a year changes from a maximum of 5º north of west to a maximum of 5°north of Solstices(至日，包括冬至、夏至) occur at the maximum points， while equinoxes(分日，包括春分、秋分) occur at the due Later Plato gave the first model that could give a reasonable account for these The model was one of the most important Greek cosmological Plato made the first serious attempt to unite astronomical phenomena and cosmological He insisted that the sun， the moon， have a combination of two regular circular motions， that’s to say， the sun and the moon have a second motion in addition the daily one， offset(偏移) at an angle to As to the five planets， which are wandering in the heaven apparently， Plato gave a similar but more complex The model could give a reasonable explanation approximately， but couldn’t explain the planets exceptive They will progress against the background of the fixed stars over a year or two， or even longer， then they will halt suddenly， and go in the other direction for a while， stop again， after that， progress in the normal Facing a series strange exceptions and motions of the planets， Eudoxus(人名，难以翻译，重要的哲学家、科学家) thought regressively(回归，追本溯源) He was a pupil of Pythagorean， and had a close relationship with P About planets， Plato’s model had two regular circular movements for each planet， Eudoxus gave four circular movements for each In this model， the first sphere (环)， generate a daily motion; the second generate the motion along the ecliptic(黄道)， the other two produce a pattern like the figure 8 laid on its sides(行星出现在黄道正负8度范围内) Besides， Eudoxus had a record of planets’ motion， and made a good use of mathematics， so compared with Plato’s model， his is more Eudoxus’ model was excellent model for a long time， but there were some inherent Because the distance between the earth and each one of five planets that we can see with naked eyes， always changes， it is not difficult to find that all planets’ size are varying Eudoxus can’t cope with the phenomenon， in his model， the distances between the earth and the planets are constant， that means the size of planets can’t Account for these problems， Ptolemy(托勒密) produced a whole new system which was to last for nearly 1500 The system was based on combination of regular circular motions He gave up concentric(同心圆) sphere model in favor of a system based on a device， the epicycle(本轮，天文模型的一种) The epicycle is a combination of two regular circular motions， but not around the same The center of smaller circle moves around the larger The two circles can produced many complex patterns， because these patterns， Ptolemy was able to explain most problems that beset the concentric sphere model， including the variation of apparent size， the brightness， the velocity(速度) of the Besides the epicycle， Ptolemy made another subtle change， the earth is offset from the center of the sun’s So the model can account for that seasons have slightly different Now before the telescope was invented and new phenomena that can’t be found with naked eyes were detected， the model is the best in the ancient After talking about some important Greek cosmological models， we have to mention an exceptive astronomer， Aristarchus(阿里斯塔克斯) He is the first one who have a revolutionary thinking that the earth is orbiting around the But sadly， we don’t know how and why he can be aware this without any idea about gravity and the phenomena which only can be detected with telescope， only we know he is a follower of A
