Saving Money

Where you save your money often depends on what you are saving for．If you are saving to buy a CD(光盘)or to go to a concert，then probably you would keep your money somewhere in your room．

If you are saving for a big purchase like a mountain bike or a school trip，where would you save your money？

One place to save money is the bank．Putting your money in a savings account will help your money earn more money．If you put your money in a piggy bank(猪形储蓄罐)，one year later you’ still have the same amount of money you put in．If you put your money in a savings account，one year later, you’ll have more money than you put in．Why？

When you keep your money in a bank，your money earns interest．Interest is an amount of money a bank pays you to use your money．The bank Users your money (and the money of other people，too)to loan money to people and businesses．

The bank will send you a statement several times a year．A bank statement tells you how much money you have in your account．It also tells you how much interest you have earned．If you leave your money in the bank，you can watch it growl Another way you can save money is to buy a certificate of deposit or CD．If you have some money that you don。t need to use for a long time，this is a good way to make your money grow．

You can buy a CD at a bank。You agree not to use the money for a certain period of time．That period might be from six months to five years．You can’t touch your money during that time, If you d0，you must pay a penalty，or fee．

第 31 题 Your money will earn more money if you put it

A．in your room．

B．in a piggy bank．

C．in your pocket．

D．in a savings account．

arily difficult to use. Last December I bought myself a video cassette recorder (VCR) described as "simple to use". In the first three weeks I failed repeatedly to program the machine to record from the TV, and after months of practice I still made mistakes. I am not a lone. According to a survey last year by Ferguson, the British manufacturer, more than in four VCR owners never use the timer on their machines to record a programme they don't use it because they've found it far too hard to operate.

So why do manufacturers keep on designing and producing VCRs that are awkward to use if the problems are so obvious？ First, the problems are not obvious to technically minded designers with years of experience and trained to understand how appliances work. Secondly, designers tend to add one or two features at a time to each model, whereas you or I face all a machine's features at once. Thirdly, although finding problems in a finished product is easy, it is too late by then to do anything about the design. Finally, if manufacturers can get away with selling products that are difficult to use, it is not worth the effort of any one of them to make improvements.

Some manufacturers say they concentrate on proving a wide range of features rather than on making the machines easy to use. But that gives rise to the question, "Why can't you have features that are easy to use*." The answer is you can.

Good design practice is a mixture of specific procedures and general principles. For a start, designers should build an original model of the machine and try it out on typical members of the public—not on colleagues in the development laboratory. Simple public trials would quickly reveal many design mistakes. In an idem world, there would be some ways of controlling quality such as that the VCR must be redesigned repeatedly until, say, 90 per cent of users can work 90 per cent of the features correctly 90 per cent of the time.

According to the passage, before a VCR is sold on the market its original model should be tried out ________.

A．among ordinary consumers who are not technically minded

B．among people who are technically minded

C．among experienced technicians and potential users

D．among people who are in charge of public relations

Call the Disk Doctorl

1 Desperate computer users who 'lose' the data from their disks can get in touch with

experts who, for a fee, will recover the lost information. One of these experts is Dave Smith, who, some years ago, set up a company called fl3ve,5 Disk Doctor Service Ltd. Dave and a few of his friends work from home and give all the money they earn to charity. The fees are always the same, no matter how precious the data on the disk is. Some people, however, are so grateful that they send extra money to Dave or to the charities his company supports. One oil company offered him Li ,000 for his help and a vet sent him a blank check

2 It would be hard to put a value on the things rescued by the Disk Doctor. There have been disks containing medical research, television scripts, manuscripts of whole books, a comedlan,5joke collection, a solicitor' s papers for a court case, and even Margaret Thatcher,5itinerary for a visit to eastern Europe. For this last case, Dave was asked if he would go in person to Mrs. Thatcher's office 'for security reasons,!

3 Disks are usually sent to the Disk Doctor by post, but sometimes people are in such

a hurry that they can't wait for the post. Radio scripts have had to be rushed by taxi to

Dave's house because they were needed for broadcasting the next day, for example. When the material has been recovered, the disk is returned to the sender with a diagnosis and a prescription for avoiding the problem in future. One grateful client, an author put a 'thank you' to Dave in the front of his book.' Dave saved mc from a cardiac arrest' , he wrote 'But,,says Dave, 'most people don't take any notice ol the doctor's advice!'

Read Passage 2 and decide whether the following statements are Jrue or False. Write T for True and F for False against the number of each of the statements on your Answer Sheet

11. Computer users can get back their lost data from their disks without any payment in Dave's company

12. The company named Dave's Disk Doctor Service Ltd is set up by Dave Smith

13. Dave and his friends earn a large amount of money, but they spend none

14. According to the different value of the data on the disk, people need to pay different amount of money for saving them

15. Most people will take notice of the disk doctor' s . advice after the disk is repaired

16. hopeless _________ (paragraph 1)

17. thankful_(paragraph 1)

18. to save _________ (paragraph 2)

ll name is the Global Positioning System and a satellite-based navigation system. Generally speaking, it is made up of a network of 24 satellites placed into orbit by the U. S. Department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. Nowadays, GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS. How does it work？ At first, GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. Secondly, GPS receivers take this information and use triangulation to calculate the users exact location. Essentially, the GPS receiver compares two times; one is the time a signal was transmitted by a satellite; the other is the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the users position and display it on the units electronic map. A GPS receiver must be locked on to the signal of at least three satellites to calculate a 2D position and track movement. With four or more satellites in view, the receiver can determine the users 3D position, here three dimensions are latitude, longitude and altitude. Once the users position has been determined, the GPS unit can calculate other information, such as speed, bearing, track, trip distance, distance to destination, sunrise and sunset time and more. How accurate is GPS？ Todays GPS receivers are extremely accurate, thanks to their parallel multi-channel design. Garmins 12 parallel channel receivers are quick to lock onto satellites when first turned on and they maintain strong locks, even in dense foliage or urban settings with tall buildings. Certain atmospheric factors and other sources of error can affect the accuracy of GPS receivers. Garmin GPS receivers are accurate to within 15 meters on average. How about the Newer Garmin GPS receivers？ With WAAS, that is Wide Area Augmentation System, its capability can improve accuracy to less than three meters on average. No additional equipment or fees are required to take advantage of WAAS. Users can also get better accuracy with Differential GPS, which corrects GPS signals to within an average of three to five meters. The U. S. Coast Guard operates the most common DGPS correction service. This system consists of a network of towers that receive GPS signals and transmit a corrected signal by beacon transmitters. In order to get the corrected signal, users must have a differential beacon receiver and beacon antenna in addition to their GPS. GPS satellites are powered by solar energy. They have backup batteries onboard to keep them running in the event of a solar eclipse, when theres no solar power. Small rocket boosters on each satellite keep them flying in the correct path. Here are some other interesting facts about the GPS satellites, also called NAVSTAR by the official of U. S. Department of Defense; the first GPS satellite was launched in 1978; a full constellation of 24 satellites was achieved in 1994; each satellite is built to last about 10 years. Replacements are constantly being built and launched into orbit; A GPS satellite weighs approximately 2 000 pounds and is about 17 feet across with the solar panels extended; transmitter power is only 50 watts or less. Now get ready to answer the questions. You may use your notes to help you answer. 18. What aspect of GPS does the talk mainly discuss？ 19. What can be inferred about the present GPS functions？ 20. According to the speaker, how accurate is a Garmin GPS receiver？ Listen again to part of the lecture. Then answer the question. Professor A GPS receiver must be locked on to the signal of at least three satellites to calculate a 2D position and track movement.

you've saved for years7 The art of letter writing seems to be dying for many people as more and more of us are turning to our computers to send a quick email. You might think the United States is a country of serious internet users, but there are many people whose only on-line activity is sending and receiving email. In 1999, Americans sent 2.2 billion email messages compared to 293 million pieces of first class mail. People have become more and more dependent on email for quick communication. In addition to the quick communication that email gives us, many people are using instant messages to communicate. How does this work？ First you make a list of your on-line friends. When you go on-line, your computer tells you if the people whose names are on the list are on-line too. If they are, you can send them an instant message and have a real time chat. Teenagers especially love sending and receiving instant messages and they love going to chat rooms to talk to their internet friends. But when people send email and instant messages, they often don't give much thought to how they write. Many people use short forms and omit capital letters. They simply write the first thing that comes into their head, click and send it. Even though people are writing more, their writing is usually not something to keep and read again years later.

How many email messages did Americans send in 1999？

A．2.2 billion.

B．2.2 million

C．293 million.

D．293 billion.
