职称英语阅读判断做题技巧
大家在做职称英语阅读判断题时，一定要注意做题步骤。做题步骤主要是根据考生们自己的做题习惯，多加练习，从而能快速高效的做题。
1、确定陈述句内容关键词。此时不认识的关键词要查字典。
常见的需要关注的关键词如下：
(1)名词(含专有名词)或名词性短语
(2)形容词、副词与其短语及其比较级
(3)数字和年代
(4)在文章中出现较少的前三项单词
(5)一目了然、容易找并有利于确定答案的单词
(6)陈述句的中心词
(7)短语优先于单词作为关键词
(8)数字和比较级优先于其原级与其它单词
(9)文章标题中的、文章出现较多的单词以及动词一般不是关键词
2、快速游览全文，根据关键词找出与该陈述句关系最密切(关联)的原文句子(可能是一句或几句话)，或是句型相似、意思相同(相近、相反)
此步骤大家可以参照两种方法：
(1)将关键词与原文的每段话第一句、中间句或最后一句相对照，把陈述句定位到原文的某一段落后再确定与其关联的句子;
(2)直接根据陈述句的`意思、句型和其所有的关键词一步到位，找出与陈述句关联的原文句子;
3、仔细阅读与陈述句关联的句子(一句或几句话)，根据这些句子的信息及其规律与陈述句进行比较，运用下面介绍的做题技巧做出正确有判断。
实战例题：
Forecasting Methods
There are several different methods that can be used to create a forecast.The method a 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 degrees today,the persistence method predicts that it will be sunny and 87 degrees 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 features6 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,using 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 direction8,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 many 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 as they were in the previous time.Even small differences between the current time and the analog can lead to very different results.
1、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.
2、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.
3、The limitation of the trends method is the same as the persistence method in that _____.
A.it makes predictions about weather.
B.it makes predictions 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.
4、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.
5、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.
