Forest Service currently predicts and tracks fires with a variety of tools, including remote automatic weather stations. But these stations are expensive and sparsely (稀疏地) distributed. Additional sensors could save trees by providing better local climate data to be used in fire prediction models and earlier warnings. However, recharging or replacing batteries by hand at very hard －to－reach locations makes it impractical and costly.The new sensor system seeks to avoid this problem by developing trees into a self－sustaining power supply. Each sensor is equipped with a battery that canbe slowly recharged using electricity produced by the tree. “A single tree doesn't generate a lot of power, but over time the trickle (细流) charge adds up, just like ________” said Shuguang Zhang, one of the researchers on the project and the associate director of the MIT's Center for Biomedical Engineering (CBE).The system produces enough electricity to allow the temperature and humidity sensors to wirelessly send out signals four times a day, or immediately if there's a fire. Each signal spreads from one sensor to another, until it reaches an existing weather station that sends the data by satellite to a forestry command center in Boise, Idaho.Scientists have long known that trees can produce extremely small amounts of electricity. But no one knew exactly how the energy was produced or how to take advantage of the power.16．What are the disadvantages of the remote automatic weather stations？a. They cost too much.b. They are of poor quality.c. They are not enough.d. They can't reach remote places.A．a, b B．b, d C．a, c D．b, c17．Which of the following is the best sentence to fill in the blank？A．Far water does not put out near fire.B．All rivers run into sea.C．Many a little makes a mickle.D．It never rains but it pours.18．What Shuguang Zhang said in Paragraph 4 means that ________.A．a single tree is enough to generate much powerB．the power from the tree can't be storedC．trees can generate enough power for our lifeD．a tree can produce the electricity to meet the needs of a sensor19．What would the author talk about after the last paragraph of the passage？A．The amount of electricity trees produce.B．How trees produce electricity.C．Trees' contribution to society.D．The research process of tree power.20．What would be the best title for the passage？A．Preventing forest fires with tree powerB．Trees can produce electricityC．Tree power in daily lifeD．Developing new energyBHow you end a computer session depends on how you use the computer, your views on energy conservation (能源的节约), and what you have been told about how your decision will affect your investment's longevity： will frequent starting and stopping cause its circuits(电路) to burn out sooner？Rest easy, your computer is more likely to be damaged by a virus picked upfrom the Internet than by being turned off and on too much. They are also energy －efficient： such efficiency has reached the point where most computers place themselves in sleep mode if they remain idle (闲置的) for a certain period of time. So your computer will likely slip into sleep mode anyway, even if you leave it on overnight.Sleep mode itself, once a pretty unreliable option—you never knew if you would be able to wake your computer without having to reboot (重新启动) it—has been vastly improved with newer operating systems. If you want your computer to consume as little energy as possible when not in use, shut it down. If you want it to consume zero energy, you're going to have to unplug (拔去……的电源插头) it.Your computer can be in only three states： on, sleep or off—each of which draws some level of ele ctric current.A computer that is “on” will either be actively processing information or sitting idle, depending on whether the user is typing a document, reading an e－mail or has stepped away briefly. The amount of wattage (瓦特数) drawn when the computer is on varies greatly depending on whether it is a laptop or a desktop computer. The latter uses more energy because desktop power supplies are less efficient and require a separate and often larger, power －hungry monitor. It also varies based on the type of work being done： complex calculations requiring intensive processing are more power－hungry, whereas writing or Web browsing consumes far less electricity.21．If sleep mode goes wrong, what will probably happen to your computer？A．It will consume as little energy as possible.B．It is more likely to be damaged by a virus picked up from the Internet.C．It will have to be rebooted when used again.D．It has to be shut down and unplugged.22．Which of the following is NOT mentioned in the text that contributes to the different amount of energy a computer consumes？A．Whether it is a laptop or a desktop computer.B．What kind of work the computer is dealing with.C．The choice of how you use your computer.D．Whether the operating systems are new.23．When does a computer consume the most energy？A．When we let it remain idle.B．When we use it to do complex calculations.C．When we use it to type some documents and e－mail.D．When we use it for surfing the Internet.24．The reason why a desktop computer uses more energy than a laptop computer is that________.A．a desktop computer's monitor is separate and often largerB．a desktop computer is larger than a laptop computer in sizeC．a desktop computer performs more kinds of work than a laptop computer D．a desktop computer is not energy－efficient25．Which of the following is implied in the first two paragraphs？A．Frequent starting and stopping can damage a computer.B．A computer's longevity depends more on the proper way you use it. C．A virus picked up from the Internet is likely to damage a computer. D．The more often you use a computer, the more smoothly it works.课时作业(八)Ⅰ.1.D考查交际用语。

Unit 3 Computers李仕才***阅读理解。

When it's five o'clock，people leave their office.The length of the workday，for many workers，is defined by time.They leave when the clock tells them they're done.These days，the time is everywhere：not just on clocks or watches，but on cellphones and computers.That may be a bad thing，particularly at work.New research shows that clock-based work schedules hinder morale(士气)and creativity.Clock-timers organize their day by blocks of minutes and hours.For example：a meeting from 9 a．m.to 10 a．m.，research from 10 a．m.to noon，etc.On the other hand，task-timers have a list of things they want to accomplish.They work down the list；each task starts when the previous task is completed.It is said that all of us employ a mix of both these types of planning.What，then，are the effects of thinking about time in these different ways？Does one make us more productive？Better at the tasks at hand？Happier? In experiments conducted by Tamar Avnet and Anne-Laure Sellier，they had participants organize different activities—from project planning，holiday shopping，to yoga—by time or to-do list to measure how they performed under “clock time” vs.“task time”．They found clock-timers to be more efficient but less happy because they felt little control over their lives.Task-timers are happier and more creative，but less productive.They tend to enjoy the moment when something good is happening，and seize opportunities that come up.The researchers argue that task-based organizing tends to be undervalued and under-supported in business culture.Smart companies，they believe，will try to bake more task-based planning into their strategies.This might be a small change to the way we view work and the office，but the researchers argue that it challenges a widespread characteristic of the economy：work organized by clock time.While most people will still probably need，and be，to someextent，clock-timers，task-based timing should be used when they are performing a job that requires more creativity.It'll make those tasks easier，and the task-doers will be happier.1．What is the way people often do their work according to the author?A．They give priority to the most urgent task on hand.B．They set a time limit for each specific task.C．They combine clock-based and task-based planning.D．They accomplish their tasks one by one.2．What did the researchers find in their experiments on clock-timers?A．They tend to be more productive.B．They seize opportunities as they come up.C．They always get their work done in time.D．They have more control over their lives.3．What is the researchers' opinion about today's business culture?A．It does not support the strategies adopted by smart companies.B．It attaches more importance to work efficiency than to workers' lives.C．It aims to bring employees' potential and creativity into full play.D．It does not lay enough emphasis on task-based practice.4．From the passage，we can conclude that ________.A．it is important to keep a balance between work and lifeB．task-based timing is preferred for doing creative workC．performing creative jobs tends to make workers happierD．a scientific standard should be adopted in job evaluation【解题导语】本文是一篇对时钟型和任务型两种工作方式的研究报告。

课时作业3Travel journalⅠ.阅读理解To American visitors, Iceland is a very interesting country, partly because it is different in so many ways from he or she is used to seeing at home. There are quite a few things that are not done, or that do not exist on the island—quite a few “No's”．There is no pollution, for instance, no dogs are permitted in Reykjavik, the capital. There is no television on Thursdays or during the entire month of July, and only three hours of black-and-white TV the rest of the time. There is no hard liquor on Wednesdays and no beer at any time. There is no handguns; only one jail of thirty-five cells (狱室) in the entire land—an admirable figure, even for a small country of 313,376 people.There is no army, air force or navy. There is no tipping for anything. There are no large stores open on Saturdays or Sundays. Since Iceland is situated just under the Arctic Circle, there is no darkness in summer and no daylight in winter. But thanks to Culf Stream, the climate is rather mild, with temperatures ranging from 34 degrees to 52 degrees in July.The rules on television liquor and guns are the result of government decisions. But the absence of pollution is due in great part to the fact that Iceland gets its power from the enormous geyser and the thousands of hot springs that come out of the ground. They provide all the energy needed by the country. In fact, Iceland uses only 3 percent of all its available power.Iceland has been described as a democratic independent country where more fish are caught and more books published per person than anywhere else in the world. The Icelanders have always felt a particular love for literature. They composed their first books in the ninth and tenth centuries AD. These works were poems and tales about the kings, heroes, and heroines of Iceland and Norway. At first, the stories were memoried and passed from generation to generation. They were finally written down between 1140 and 1220. The Icelanders have never stopped writing ever since. “Rather shoeless than bookless，”they proudly say.1．American visitors enjoy visiting Iceland probably because ________.A．no dogs are permitted in the capitalB．the police do not carry handgunsC．the climate is rather mildD．it is very different from Americans2．The following statements are true EXCEPT ________.A．there are no soldiers in IcelandB．the Icelanders don't drink beerC．there is no tip of any kindD．there are no crimes in Iceland3．There is no pollution in Iceland mainly because ________.A．Iceland uses only 3 percent of all its available powerB．the Icelanders use hot water from the ground below astheir energyC．it is located just under the Arctic CircleD．it is a democratic independent country4．“Rather shoeless than bookless” means ________.A．they prefer not to have shoe or booksB．they would rather have shoes on than write booksC．they prefer travelling to readingD．they regard books more important than shoes答案与解析1．D细节理解题。

In one sense，it already has.Today's most complicated mobile phones have the processing power of a mid－1990s PC while using 100 times less electricity.And more and more of today's mobile phones have computer－like features，allowing their owners to send e－mails，browse(浏览)the Web and even take photos? 84 million mobile phones with digital cameras were shipped last year.We ask the question whether mobile phones will ever overshadow or replace the PC，and the issue suddenly becomes questionable.PC supporters say mobile phones are too small and connect too slowly to the Internet to become effective at tasks now performed on the large screens and keyboards of today's computer.Fans of the mobile phones respond: just ing techniques will solve the limitation of the mobile phon e.“One day，two or three billion people will have cell phones，and they are not going to have PCs，” says one inventor of the smart phone and the chief technology officer of an important smart phone company.“The mobile phone will become their digital life.”The inventor's a newest product，the shiny，slim pocket－size cell phone，has a tiny keyboard，a built－in digital camera and narrow openings for added memory.The smart phone market makes up only five percent of overall mobile phone sales today，but the figure has been doubling each year.In the United States，it's the business crowd that's primarily buying these handsets.“What makes the smart phone so much better than the computer is that it's always with you，always up and always ready，” says one of them，who works in an 80－member law firm，which recently started giving its lawyers smart phones instead of laptops.【文章大意】本文是一篇议论文，针对手机将来是否会取代电脑，不同的人群有不同的观点。
