第一篇

　　Forecasting Methods

　　There are several different methods that can be used to create a forecast. The method forecaster chooses depends upon the experience of the forecaster, the amount of information available to the forecaster, the level of difficulty that the forecast situation presents, and the degree of accuracy or confidence needed in the forecast.

　　The first of these methods is the persistence method;the simplest way of producing a forecast. The persistence method assumes that the conditions at the time of the forecast will not change. For example, if it is sunny and 87 degree today, the persistence method predicts that it will be sunny and 87 degree tomorrow. If two inches of rain fell today, the persistence method would predict two inches of rain for tomorrow. However, if weather conditions change significantly from day to day, the persistence method usually breaks down and is not the best forecasting method to use.

　　The trends method involves determining the speed and direction of movement for fronts, high and low pressure centers, and areas of clouds and precipitation. Using this information, the forecaster can predict where he or she expects those features to be at some future time. For example, if a storm system is 1,000 miles west of your location and moving to the east at 250 miles per day, suing the trends method you would predict it to arrive in your area in 4 days. The trends method works well when systems continue to move at the same speed in the same direction for a long period of time. if they slow down, speed up, change intensity, or change direction, the trends forecast will probably not work as well.

　　The climatology method is another simple way of producing a forecast. This method involves averaging weather statistics accumulated over man years to make the forecast. For example, if you were using the climatology method to predict the weather for new York City on July 4th, you would go through all the weather data that has been recorded for every July 4th and take an average. The climatology method only works well when the weather pattern is similar to that expected for the chosen time of year. if the pattern is quite unusual for the given time of year, the climatology method will often fail.

　　The analog method is a slightly more complicated method of producing a forecast. It involves examining today"s forecast scenario and remembering a day in the past when the weather scenario looked very similar (an analog). The forecaster would predict that the weather in this forecast will behave the same as it did in the past. The analog method is difficult to use because it is virtually impossible to find a predict analog. Various weather features rarely align themselves in the same locations they were in the previous time. Even small differences between the current time and the analog can lead to very different results.

　　31　What factor is NOT mentioned in choosing a forecasting method? __________

　　A　Imagination of the forecaster.

　　B　Necessary amount of information.

　　C　Practical knowledge of the forecaster.

　　D　Degree of difficulty involved in forecasting.

　　32　Persistence method will work well __________.

　　A　if weather conditions change greatly from day to day

　　B　if weather conditions do not change much

　　C　on sunny days

　　D　on rainy days

　　33　The limitation of the trends method is the same as the persistence method in that __________.

　　A　it makes predications about weather

　　B　it makes predications about precipitation

　　C　the weather features need to be well defined

　　D　the weather features need to be constant for a long period of time

　　34　Which method may involve historical weather data? __________

　　A　The trends method.

　　B　The analog method.

　　C　Both climatology method and analog method.

　　D　The trends method and the persistence method.

　　35　It will be impossible to make weather forecast using the analog method __________.

　　A　when the current weather scenario differs from the analog

　　B　when the current weather scenario is the same as the analog

　　C　when the analog is over ten years old

　　D　when the analog is a simple repetition of the current weather scenario

　　Lateral Thinking

　　Lateral thinking (迂回思维), first described by Edward de Bono in 1967, is just a few years older than Edward"s son. You might imagine that Caspar was raised to be an adventurous thinker, but de Bono name was so famous, Casper"s parents worried that any time he would say something bright at school, his teachers might snap, “Where do you get that idea from?”

　　“We had to be careful and not overdo it,” Edward admits. Now Casper is at Oxford --which once looked unlikely because he is also slightly dyslexic (诵读困难). In fact, when he was applying to Oxford, none of his school teachers thought he had a chance. “So then we did several thinking sessions,” his father says, “using my techniques and, when he went up for the exam, he did extremely well.” Soon after, Edward de Bono decided to write his latest book, “Teach Your Children How to Think”, in which he transforms the thinking skills he developed for brain-storming businessmen into informal exercises for parents and children to share.

　　Thinking is traditionally regarded as something executed in a logical sequence, and everybody knows that children aren"t very logical. So isn"t it an uphill battle, trying to teach them to think? “You know,” Edward de Bono says, “if you examine people"s thinking, it is quite unusual to find faults of logic. But the faults of perception are huge! Often we think ineffectively because we take too limited a view. ”

　　“Teach Your Child How to Think” offers lessons in perception improvement, of clearly seeing the implications of something you are saying and of exploring the alternatives.

　　36　What is TRUE about Casper? __________

　　A　He is Edward"s son.

　　B　He is an adventurous thinker.

　　C　He first described lateral thinking.

　　D　He is often scolded by his teacher.

　　37　Casper succeeded in applying to Oxford because __________.

　　A　he was careful and often overworked

　　B　all of his school teachers thought he had a chance

　　C　he used in the exam the techniques provided by his father

　　D　he read the book “Teach Your Child How to Think” before the exam

　　38　It can be inferred from Paragraph 2 that Edward __________.

　　A　was likely to improve children"s logic with his book

　　B　gave a description of lateral thinking several years after his son was born

　　C　was prompted to study lateral thinking because his son was slightly dyslexic

　　D　once taught businessmen how to think before he wrote for parents and children

　　39　According to Paragraph 3, which of the following statements expresses Edward de Bono"s view? __________

　　A　Everybody knows that children aren"t very logical.

　　B　It is an uphill battle trying to teach children to think.

　　C　We often think ineffectively because we take too limited a view.

　　D　Thinking is traditionally regarded as something executed in a logical sequence.

　　40　Lateral thinking refers to the following EXCEPT __________.

　　A　improving one"s logic in thinking

　　B　improving one"s perception in thinking

　　C　seeing the implications of what you are saying

　　D　exploring the alternatives for what you are saying
