那里能找到关于太阳能介绍的英文文章
The solar energy is an energy which the solar interior continuously unceasing nuclear fusion reaction process produces. On the earth's orbit mean sun radiation intensity is 1367kw/m2. The terrestrial equator perimeter is 40000km, thus may calculate, the Earth obtains the energy may reach 173,000TW. In the sea level standard peak value intensity is 1kw/m2, the earth's surface some 24h annual mean radiation intensity is 0.20kw/m2, is equal to has 102,000TW the energy, the humanity relies on these energy maintenance survivals, including possesses other forms the renewable energy (geothermal energy resources to be an exception) although the solar energy resources total quantity is equal the energy which uses to the present humanity 10,000 multiple, but the solar energy energy density is low, moreover it 因地而异, from time to time because changes, this is the development the main question which faces using the solar energy. Solar energy these characteristics can cause it to receive the certain limit in the entire synthesis energy system function.

太阳能是太阳内部连续不断的核聚变反应过程产生的能量。地球轨道上的平均太阳辐射强度为1367kw/m2。地球赤道的周长为40000km,从而可计算出,地球获得的能量可达173,000TW。在海平面上的标准峰值强度为1kw/m2,地球表面某一点24h的年平均辐射强度为0.20kw/m2,相当于有102,000TW 的能量,人类依赖这些能量维持生存,其中包括所有其他形式的可再生能源(地热能资源除外)虽然太阳能资源总量相当于现在人类所利用的能源的一万多倍,但太阳能的能量密度低,而且它因地而异,因时而变,这是开发利用太阳能面临的主要问题。太阳能的这些特点会使它在整个综合能源体系中的作用受到一定的限制。
谁能帮我找一篇关于太阳能(solar energy)的文章````(要英文的)
Solar power is the energy from the sun that is converted into thermal or electrical energy. The direct collection of solar energy involves artificial devices, called solar collectors, that are designed to collect the energy, sometimes through prior focusing of the sun's rays. The energy, once collected, is used in a thermal process or a photo-electric, or photo-voltaic, process. In thermal processes, solar energy is used to heat a gas or liquid, which is then stored or distributed. In the photo-voltaic process, solar energy is converted directly to electrical energy without intermediate mechanical devices. Solar collectors are of two fundamental types: flat plate collectors and concentrating collectors. A futuristic scheme that has been proposed to produce power on a large scale envisions placing giant solar modules in geosynchronous earth orbit, where energy generated from sunlight would be converted to microwaves and beamed to antennas on earth for re-conversion to electric power.
Unless we contrive more efficient ways to develop alternative energy within this century we will face major problems because energy consumption is increasing year by year, so do the pollution.

阅读是人们获取信息的重要途径。对于我国中学英语教学来说,阅读始终为中学英语教学的关键组成部分,而高考英语是中学英语教学中非常关键的组成部分。下面就是我给大家整理的高考 英语阅读 文章 ,希望大家喜欢。
高考英语阅读文章篇一:交友
Many of us mistakenly believe that it's wrong to think we have any good qualities. We may spend a lot of time blaming ourselves for our negative qualities, thinking that self criticism is the key to improving our performance. However, a constant focus on our supposed shortcomings can stop our efforts to make friends with other people. How can we believe that others could like us if we believe our inner being is flawed(有缺陷)?
If someone seems to dislike you, the reason for that dislike might have little or nothing to do with you. The person who doesn't like you might be fearful, or shallow, or busy or shy. Perhaps you and that person are simply a mismatch for each other at this particular time.
Don't take yourself out of the game by deciding that your flaws are bigger than your good qualities. In fact, some o f the very qualities you consider to be flaws may be irresistible to someone else. For all the factors that might cause one person to reject you, there are at least as many factors that will work in your favor with someone else.
You might be thirty pounds over your ideal weight, but you may have a wonderful laugh and a real enthusiasm for life. There are many people who don’t mind your extra pounds. You may drive a shabby car, but you might be a great dancer and a loyal friend. There are people out there looking for loyalty, or fun, or sweetness, or wisdom, and the package it comes in is not important. If you are worried that you are not beautiful enough to attract friends, keep in mind that not everyone is looking for physical beauty in their friends. You can decide to feel inferior(自卑) because you don't have much money and you don't drive a nice car. You can believe that this is the reason that you don't have many friends in your life. On the other hand, if you are very wealthy you may be suspicious that everyone is after your money and that nobody really likes yo u as a person.
The point is that you can focus on just about anything and believe it's the reason you do not have friends and cannot make any.
36. According to the author ___________ plays an important role in making friends.
A. admitting your shortcomings B. self criticism C. modesty D. confidence

高考英语阅读文章篇二:太阳能
Sunny countries are often poor. A shame, then, that solar power is still quite expensive. Eight19, a British company by Cambridge University, has, however, invented a novel way to get round this. In return for a deposit of around $10 it is supplying poor Kenyan families with a solar cell able to generate 2.5 watts of electricity, a battery that can deliver a three amp(安培) current to store this electricity, and a lamp whose bulb is a light-emitting diode(二极管). The firm thinks that this system, once the battery is fully charged, is enough to light two small rooms and to power a mobile-phone charger for seven hours. Then, next day, it can be put outside and charged back up again.
The trick is that, to be able to use the electricity, the system's keeper must buy a scratch card—for as little as a dollar—on which is printed a reference number. The keeper sends this reference, plus the serial number of the household solar unit, by SMS to Eight19. The company's server will respond automatically with an access code to the unit.
Users may consider that they are paying an hourly rate for their electricity. In fact, they are paying off the cost of the unit. After buying around $80 worth of scratch cards—which Eight19 expects would take the average family around 18 m onths—the user will own it. He will then have the option of continuing to use it for nothing, or of trading it in for a bigger one, perhaps driven by a 10-watt solar cell.
In that case, he would go then through the same process again, paying off the additional cost of the upgraded kit at a slightly higher rate. Users would therefore increase their electricity supply steadily and affordably.
According to Eight19's figures, this looks like a good deal for customers. The firm believes the average energy-starved Kenyan spends around $10 a month on oil—enough to fuel a couple of smoky lamps—plus $2 on charging his mobile phone in the market-place. Regular users of one of Eight19's basic solar units will spend around half tha t, before owning it completely. Meanwhile, as the cost of solar tech nology falls, it should get even cheaper.
41. The underlined word “get round” in the first paragraph can be replaced by _______ .
A. make use of B. come up with C. look into D. deal with
【答案】D
【解析】词义猜测题。make use of利用; come up with想出; look into调查; deal with处理。根据solar power is still quite expensive及Eight19, a British company by Cambridge University, has, however, invented a novel way to因为太阳能仍然很贵,所以Eight19发明了一个新的 方法 来解决这个问题,故选D。
42. What should the user do when the electricity in the battery is used up?
A. Buy a scratch card.
B. Recharge it outside.
C. Buy another solar cell.
D. Return it to the company.
【答案】B
【解析】细节理解题。根据文章第一段最后一句Then, next day, it can be put outside and charged back up again.可知没有电了,你可以把它放在外面重新充电,故选A。
43. How much would users pay for the cell and scratch cards before they own a 2.5-watt solar cell?
A. Around $10. B. Around $80. C. Around $90. D. Around $180.
【答案】C
【解析】细节理解题。根据文章1,3段After buying around $80 worth of scratch cards—which Eight19 expects would take the average family around 18 months—the user will own it. 和In return for a deposit of around $10 it is supplying poor Kenyan families with a solar cell able to generate 2.5 watts of electricity可知在你拥有这些之前,你要花费90元。故选C。
44. It can be inferred from the last paragraph that __________ __.
A. Kenyan families would find it difficult to afford the solar cell
B. using the solar cell would help Kenyan families save money
C. few Kenyan families use mobile phones for lack of electricity
D. the company will make a great profit from selling solar cells
【答案】B
【解析】推理判断题。根据文章最后一段The firm believes the average energy-starved Kenyan spends around $10 a month on oil—enough to fuel a couple of smoky lamps—plus $2 on charging his mobile phone in the market-place. Regular users of one of Eight19's basic solar units will spend around half that, before owning it completely. Meanwhile, as the cost of solar technology falls, it should get even cheaper.可知这样做会让太阳能的成本降低,会给肯尼亚的人来到好处。故选B。
45. What might be the most suitable title for the passage? A. Solar Energy: Starting from Scratch.
B. Eight19: a creative British Company.
C. Kenyan Families: Using Solar Energy for Free.
D. Poor Countries: Beginning to Use Solar Ene rgy
【答案】A
【解析】标题归纳题。根据文章主题段第一段内容可知本文讲述的是Eight19,这家英国的公司所采用的使用太阳能的一种新的方法,故选A。
高考英语阅读文章篇三:加薪
While Andrew was getting ready for work one Friday morning, he announced to his wife that he had finally decided to ask his boss for a salary raise. All day Andrew felt nervous and anxious as he thought about the upcoming showdown. What if Mr Larchmont refused to grant his request? Andrew had worked so hard in the last 18 months and landed some great accounts for Braer and Hopkins Advertising Agency. Of course, he deserved a wage increase.
The thought of walking into Larchmont’s office left Andrew weak in the knees. Late in the afternoon he was finally courageous enough to approach his superior. To his delight and surprise, the ever-frugal(一向节俭的)Harvey Larchmont agreed to give Andrew a raise!
Andrew arrived home that evening—despite breaking all city and state speed limits—to a beautiful table set with their best china, and candles lit. His wife, Tina, had prepared a delicate meal including his favorite dishes. Immediately he figured someone from the office had tipped her off!
Next to his plate Andrew found a beautiful lettered note. It was from his wife. It read: “Congratulations, my love! I knew you’d get the raise! I prepared this dinner to show just how much I love you. I am so proud of your accomplishments!” He read it and stopped to reflect on how sensitive and caring Tina was.
After dinner, Andrew was on his way to the kitchen to get dessert when he observed that a second card had slipped out of Tina’s pocket onto the floor. He bent forward to pick it up. It read: “Don’t worry about not getting the raise! You do deserve one! You are a wonderful provider and I prepared this dinner to show you just how much I love you even though you did not get the increase.”
Suddenly tears swelled in Andrew’s eyes. Total acceptance! Tina’s support for him was not conditional upon his success at work.
The fear of rejection is often softened and we can undergo almost any setback or rejection when we know someone loves us regardless of our success or failure.
31. What was Andrew’s plan that Friday?
A. To request a wage increase from his boss.
B. To get a job with the Braer and Hopkins Advertising Agency.
C. To celebrate his success with his wife at home.
D. To ask his boss to come for dinner.
【答案】A
【解析】细节理解题。由“he announced to his wife that he had finally decided to ask his boss for a salary raise.”可知他打算要求老板给他加薪。故选A。
32. On his way back home, Andrew _________.
A. felt weak in the knees
B. was punished by the traffic policeman
C. was too anxious to share the news
D. couldn’t wait to enjoy a meal
【答案】C
【解析】细节理解题。由“Andrew arrived home that evening—despite breaking all city and state speed limits”中“尽管超出了城市及国家的最高车速”可 知Andrew车开的很快,说明他很急切地回家去分享这个好消息。故选C。
33. Which of the following statements about the story is FALSE?
A. Andrew was afraid that his request would lead to disaster.
B. Andrew had worked very hard and done his part for the company.
C. Andrew’s boss agreed to his request.
D. One of Andrew’s colleagues had told his wife the good news.
【答案】D
【解析】推理判断题。第五段“a second card had slipped out of Tina’s pocket onto the floor.”提到妻子还写了一封信。根据后面信的内容,妻子不知道他加薪的要求是否取得了老板的同意而准备了两封信。所以没有人告诉他妻子这个好消息。故选D。
34. Why did Tina prepare a grand dinner for Andrew that day?
A. She was confident of his getting a pay raise.
B. She meant to show her support whatever the result would be.
C. She believed t hat her husband was the best in his company.
D. She wanted to express her gratitude for his devoti on to the family.
【答案】B
【解析】细节理解题。“Tina’s support for him was not conditional upon his success at work. ”说明Tina对他的支持不是基于他在工作上的成功。无论结果如何她都会支持他。故选B。
35. We can conclude from the text that ______.
A. we should never be afraid to ask for what is due to us
B. work hard and you will be rewarded
C. many fears turn out to be unfounded
D. unconditional love brin gs courage and strength
