A weather map is an important tool for geographers. A succession of three or four maps presents a continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts（冷暖空气团接触的锋）to determine whether an individual pressure area is deepening or becoming shallow and whether a front is increasing or decreasing in intensity. They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal a synoptic picture of conditions in the atmosphere at a given time.
All students of geography should be able to interpret a weather map accurately. Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States Weather Bureau issues information about approaching storms, floods, frosts, droughts, and all climatic conditions in general. Twice a month it issues a 30-day “outlook” which is a rough guide to weather conditions likely to occur over broad areas of the United States. These 30-day outlooks are based upon an analysis of the upper air levels which often set the stage for the development of air masses, fronts, and storms.
Considerable effort is being exerted today to achieve more accurate weather predictions. With the use of electronic instruments and earth satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations (气象站). Extensive experiments are also in progress for weather modification（改变）studies. But the limitations of modification have prevented meteorological results except in the seeding of super-cooled, upslope mountainous winds which have produced additional orographic (山岳形态的) precipitation on the windward side of mountain ranges. Nevertheless, they have provided a clearer understanding of the fundamentals of weather elements.

Perhaps you have a big test coming up and you are feeling nervous. You know you have got to do well. The pressure is on, so you may be losing sleep and the ability to concentrate. How can you deal with the stress, study effectively, and take the test with confidence? Maybe you should try meditation（沉思）.

When people think about meditation, many pictures of old men’s sitting cross-legged on remote mountaintops will appear in mind. People describing meditation frequently mention elements such as relaxation and “thinking about nothing”.

It is not necessary to travel to a mountaintop to enjoy the benefits of meditation because it is actually more about awareness than just relaxation. The secret of meditation is breathing.

To star meditating, find a place where you can sit or stand comfortably for a little while and concentrate. Close your eyes and start taking slow breaths. Focus on the air moving in and out of your body. If your mind starts to wander and you begin to think about something else, refocus your attention on your breathing.

Meditation has little to do with escaping problems or thinking about nothing. Instead, the breathing techniques help you calm down and think more clearly about your feelings. The issues on your mind unfold clearly, as if they were in slow motion.

This clarity（清晰）is called “mindfulness”. Being mindful means that you are aware of what you are thinking without becoming caught up in your thoughts. It takes practice, but with time, that big test will not scare you anymore. You will realize through meditation that fear is just a product of not being mindful.

64． What is the best way to reduce the pressure if one faces a big test?

A. To climb up to the top of a mountain for a rest.

B. To sit on the top of a mountain without thinking anything.

C. To sit or stand comfortable and begin to meditate.

D. To sit quietly with one’s legs crossed.

65． What should a person do if his mind begins to wander while meditating?

A. Stop meditating.

B. Concentrate on breathing again.

C. Involve himself in his thoughts.

D. Close eyes immediately.

66． From the passage we can learn that by practicing meditation we’ll__________.

A. not be stuck in our thoughts

B. pass the examinations easily

C. realize fear is a product of too much thought

D. never be afraid of big tests

67． From the passage we can know the writer’s purpose is to let the readers know__________

A. how to deal with the stress before a big test

B. what is meditation

C. how a big test scares the students

D. where is the best place to relax

After moving to the United States, immigrant groups trying to fit in tend to choose high calorie fatty foods in an attempt to appear more American，a new study finds．That's one reason why immigrants approach US levels of obesity within 15 years of moving to America．
The researchers also did an experiment that measured whether or not the threat of appearing un-American influenced respondents' food choices．After being questioned about their ability to speak English，75 percent of Asian-Americans identified a typical American food as their favorite. Only 25 percent of Asian-Americans who had not been asked if they spoke English did the same.
When their American identity was called into question during a follow-up study, Asian-American participants also tended to choose typical American dishes，such as hamburgers and cheese sandwiches．In that experiment, 55 Asian-Americans were asked to choose a meal from a local Asian or American restaurant. Some participants were told that only Americans could participate in the study. Those who chose the more typical American fare ended up consuming an extra 182 calories，including 12 grams of fat and 7 grams of saturated fat（饱和脂肪）.
"People who feel like they need to prove they belong to a culture will change their habits in an attempt to fit in，"said Sauna Cheryan，an author of the study and assistant professor of psychology at the University of Washington." If immigrants and their children choose unhealthy American foods over healthier traditional foods across their lives，this process of fitting in could lead to poorer health." Cheryan added．
Social pressures，the study concluded, are at the heart of the problem．"In American society today, being American is associated with being white．Americans，who don't fit this image even if they were born here and speak English，feel that pressure to prove that they're American," said Cheryan．
