[单项选择]
A few common misconceptions. Beauty is only skin-deep. One’s physical assets and liabilities don’t count all that much in a managerial career. A woman should always try to look her best.
Over the last 30 years, social scientists have conducted more than 1,000 studies of how we react to beautiful and not-so-beautiful people. The virtually unanimous conclusion: Looks do matter, more than most of us realize. The data suggest, for example, that physically attractive individuals are more likely to be treated well by their parents, sought out as friends, and pursued romantically. With the possible exception of women seeking managerial jobs, they are also more likely to be hired, paid well, and promoted.
Un-American, you say, unfair and extremely unbelievable Once again, the scientists have caught us mouthing pieties (虔诚) while acting just the contrary. Their typical experiment works something like this. They give each member of a group—college students

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 per-
sistence 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（降水量）.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,using the trends method you
would predict it 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 intensi-
ty,or change directions,the trends forecast will probably not work as well.
The climatology（气候学）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 oniy
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（模式）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 ii
did in the past.The analog method is difficult to use because it is virtually impossible to find a predict ana-
log.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.
The analog method should not be used in making a weather forecast when________.
A.the current weather scenario is different from the analog
B.the analog looks complicated
C.the analog is more than 10 years old
D.the current weather scenario is exactly the same as the analog
