题文
阅读理解。 Have you ever been frustrated (沮丧的) when left talking to yourlf after your mobile phone battery runs out in the middle of a call? If yes, then here comes some good news. Scientists are now perfecting a way to recharge (充电) electrical equipment while on the move. Rearchers from the Netherlands, France and Portugal announced last week that they have developed very thin solar panels (太阳能板) that can be put on clothes. They can also be added to furniture and rooftops. They change light from the sun into electricity. In about three years, you'll be able to wear a jacket that will recharge your phone as you walk. For camping fans, the development could lead to a tent which charges batteries all day so you can have light or music at night. The basic technology of wearable solar panels is the same as that ud for conventional (传统的) solar panels. Pairs of sheets of mi-conducting silicon (半导体硅) are linked together to form the panel. But scientists made them much thinner by using different silicon. At one micro-metre, they are the same thickness as photographic film. "This technology will make it easier for people to u clean energy sources," said Gerrit Kroen, a physicist in the Netherlands who led the team of scientists. But the thin panels are not as efficient as the thicker ones. While some solar panels now operate at an efficiency of about 20 per cent, the new flexible (柔韧的) panels are only 7 per cent efficient. But the scientists believe that this is worth accepting for a stronger and more uful panel. But the thinner panel is cheaper. An A4 sized panel put onto the back of a jacket costs less than US$13. It could charge a cellphone during a summer walk in the countryside. As long as you stay within range of the transmitting masts (发射天线) that relay a call to the networks, phones will never again run out of power.1. What is the meaning of the phra "on the move" in paragraph 2?A. Taking a cour of action. B. Going from one place to another. C. Changing clothes before moving. D. Changing the mobile phone battery.2.What is the passage mainly about?A. A way to recharge electrical equipment. B. A new kind of chargeable battery. C. A new type of mobile phone. D. A u of mobile phones. 3.What is the most important in the development of the technology? A. Photographic film. B. Warmer clothes. C. Furniture and rooftops. D. Thin flexible solar panels.4.What is NOT likely to happen in the future? A. You can listen to music in a campsite using the electricity from sunshine. B. Your mobile phone battery runs out in the middle of a call. C. You wear a jacket that will recharge your phone. D. You can change light from the sun into electricity. 题型:未知难度:其他题型答案

考点
据考高分专家说,试题“阅读理解。 Have you .....”主要考查你对 [健康环保类阅读 ]考点的理解。 健康环保类阅读健康环保累阅读概念:
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。体裁有记叙文、 说明文、议论文和各种应用文。
健康环保类文章阅读技巧:
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考,理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文,从结构上看大致可分为三个部分: 第一部分一般是文章的首段,主要用来提出文章的主题,即文章想要阐述、说明的主要内容; 第二部分是文章的主体,可由若干个段落组成,对文章的主题进行展开说明; 第三部分是结尾段,对文章的主题进行归纳总结。这类文章多用一般现在时,而且一般多使用客观性词语表述。有时为了强调客观性,也常使用被动语态。 从近几年的考试题来看,科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节,很多同学对此类文章感到费解。但一般的科普类文章都是就事论事,需要逻辑推理和想象的时候较少,因此此类阅读题也没有同学们想象中的那么难,只要多加训练,就能较好地答题。【阅读策略】 1、概要(Summarizing): 阅完材料后,将所阅材料浓缩,摘要,做出所阅材料的书面或口头梗概。 2、组织(Organization): 阅读后根据阅读内容,识别观点、人物、事件之间的关系以及文章的结构关系。如:时间关系、比较或对比关系、相关关系及因果关系等。
