A weather map is an important tool for geographers. A series 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; to determine whether a pressure area is deepening or becoming shallow and whether a front is increasing or decreasing in intensity (强度) .They are also able to determine whether an air mass is keeping its original characteristics or taking on those of the surface over which it is moving. Thus,a most important function of the map is to show a general 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 a large 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 and all climatic conditions in general. Twice a month it issues a 30-day “out-look” 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.
Much effort is being made today to achieve more accurate weather predictions. With the use of electronic instruments and earth satellites,big gains have taken place recently in recognizing and tracking storms over regions which have few meteorological stations（气象台）. A lot of experiments are also in progress for weather modification（人工改变天气) studies. But the limitations of weather modification have produced few results except in the seeding（撒干冰） of super cooled,upslope mountainous winds which have produced additional rainfall on the windward(上风的) side of mountain ranges.

In difficult economic times,people tend to become 1. in their daily lives.That is to say,they cut back on 2. activities and keep what is 3. For example,people who are used to eating out on a daily basis may decide to eat at home 4. nights each week. Or they may choose to socialise by having people over for a home-cooked dinner. Another method of saving is cutting down on visits to personal care services. Instead of going on vacations to far-away places,people take car trips to 5. destinations.Memberships to sports clubs are seen as luxuries (奢侈品) ，while memberships to gyms are viewed as 6. . Clothing purchases become more practical. Matching shoes to clothes is a thing of the past — unfashionable.
What does not change is 7. . People continue buying their children toys and taking them to amusement parks. People continue buying 8. technological inventions in televisions,computers,and phones. This is logical because they still need entertainment and these are in-house options. People buy foods in their supermarkets,and they buy fancy kitchen equipment. In 9. ，in tough times,people change their big out-of-house luxuries to little in-house luxuries. Parents set 10. their comfort for their children's needs. Big showy expenses are in poor taste. Small,in-home expenses are in good taste.
8. Just as my grandpa often (make / put) it'success is ninety-nine percent mental attitude.
3. Perhaps a more (caution) approach would bring better results.
10. All my family are well (educate) , of whom my brother studied in Harvard University.
9. Peter was laughing hard,but his wife was laughing (the hardest / even harder) !
3. Drivers (make) to drive more carefully after the stricter traffic law takes effect.
8. —The last one (arrive) pays the meal.
—Agreed!
