7、r invention with a relatively simple design that allows us to point at things on the computer and it is very productive. Think of all the things you can do with a mouse like selecting text for copying and pasting, drawing, and even scrolling on the page with the newer mice with the wheel. Most of us

8、 use the computer mouse daily without stopping to think how it works until it gets dirty and we have to learn how to clean it. We learn to point at thing before we learn to speak, so the mouse is a very natural pointing device. Other computer pointing devices include light pens, graphics tablets and

9、 touch screen, but the mouse is still our workhorse.The computer mouse was invented in 1964 by Douglas Englehart of Stanford University. As computer screens became popular and arrow keys were used to more around a body of text, it became clear that a pointing device that allowed easier motion throug

10、h the text and even selection of text would be very useful. The introduction of the mouse, with the Apple Lisa computer in 1983, really started the computer public on the road to relying on the mouse for routine computer tasks.How does the mouse work? We have to start at the bottom, so think upside

11、down for now. It all starts with mouse ball. As the mouse ball in the bottom of the mouse rolls over the mouse pad, it presses against and turns two shafts. The shafts are connected to wheels with several small holes in them. The wheels have a pair of small electronic light-emitting devices called l

12、ight emitting diodes (LED) mounted on either side. One LED sends a light beam to the LED on the other side. As the wheels spin and a hole rotates by, the light beam gets through to the LED on the other side. But a moment later the light beam is blocked until the next hole is in place. The LED detect

13、s a changing pattern of light, converts the pattern into an electronic signal, and sends the signal to the computer through wires in a cable that goes out the mouse body. This cable is the tail that helps give the mouse its name. The computer interprets the signal to tell it where to position the cu

14、rsor on the computer screen.So far we have only discussed the basic computer mouse that most of you probably have or have used. One problem with this design is that the mouse gets dirty as the ball rolls over the surface and picks up the dirt. Eventually you have to clean your mouse. The newer optic

By moving goods from p

19、laces where they are plentiful to places where they are scarce, transport adds to their value. The more easily goods can be brought over the distance that separates producer and consumer, the better for trade. When there were no railways, no good roads, no canals, and only small sailing ships, trade

20、 was on a, small scale.2 The great advances made in transport during the last two hundred years were accompanied by a big increase in trade. Bigger and faster ships enabled a trade in meat to develop between Britain and New Zealand, for instance. Quicker transport makes possible mass-production and

21、big business, “drawing supplies from, and selling goods to, all parts of the globe. Big factories could not exist without transport to carry the large number of workers they need to and from their homes. Big city stores could not have developed unless customers could travel easily from the suburbs a

22、nd goods delivered to their homes. Big cities could not survive unless food could be brought from a distance.3 Transport also prevents waste. Much of the fish landed at the ports would be wasted if it could not be taken quickly to inland towns. Transport has given us a much greater variety of foods

23、and goods since we no longer have to live on what is produced locally. Foods which at one time could be obtained only during a part of the year can now be obtained all through the year. Transport has raised the standard of living.4 By moving fuel, raw materials, and even power, as, for example, thro

24、ugh electric cables, transport has led to the establishment of industries and trade in areas where they would have been impossible before. Districts and countries can concentrate on making things which they can do better and more cheaply than others and can then exchange them with one another. The c

25、heaper and quicker transport becomes, the longer the distance over which goods can profitably be carried. Countries with poor transport have a lower standard of living.5 Commerce requires not only the moving of goods and people but also the carrying of messages and information. Means of communicatio

26、n, like telephones, cables and radio, send information about prices, supplies, and changing conditions in different parts of the world. In this way, advanced communication systems also help to develop trade.A. Higher living standardB. Importance of transport in tradeC. Various means of transportD. B

34、of supplies he would need. When he finally opened with a capital of $ 1,500 ,he set up his office in the kitchen and his printing press in the garage.

40、ory tests aboard NASAs Phoenix Mars Lander have identified water in a soil sample. The landers robotic arm delivered the sample Wednesday to an instrument that identifies vapors produced by the heating of samples.“We have water,“ said William Boynton of the University of Arizona, lead scientist for

41、the Thermal and Evolved-Gas Analyzer, or TEGA. “This is the first time Martian water has been touched and tasted. “The robotic arm is a critical part of the Phoenix Mars mission. It is needed to trench into the icy layers of northern polar Mars and deliver samples to instruments that will analyze wh

42、at Mars is made of, what its water is like, and whether it is or has ever been a possible habitat for life.The soil sample came from a trench approximately 2 inches deep. When the robotic arm first reached that depth, it hit a hard layer of frozen soil. Two attempts to deliver samples of icy soil on

43、 days when fresh material was exposed were foiled when the samples became stuck inside the scoop. Most of the material in Wednesdays sample had been exposed to the air for two days, letting some of the water in the sample vaporize away and making the soil easier to handle.“Mars is giving us some sur

44、prises,“ said Phoenix principal investigator Peter Smith of the University of Arizona. “Were excited because surprises are where discoveries come from. One surprise is how the soil is behaving. The ice-rich layers stick to the scoop when poised in the sun above the deck, different from what we expec
