A weather map is an important tool for geographers. A succession of three or four maps

Questions 16 to 20are based on the following passage

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; 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 condition 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.

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. Extensive experiments are also in progress for weather modification studies. But the limitations of weather modification have prevented meteorological results except in the seeding of super?cooled, upslope mountainous winds which have produced additional rainfall on the windward side of mountain ranges. Nevertheless, they have provided a clearer understanding of the fundamentals of weather elements.

16. The observation of weather conditions by satellites is advantageous because it_______.

A. enables man to alter the weather

B. makes weather prediction easier

C. gives the scientist information not obtained readily otherwise

D. uses electronic instruments

17 . One characteristic of weather maps NOT mentioned by the author in this passage is

A. fronts   B. thermal changes

C. Frost   D. wind speed

18. The thirty-day forecast is determined by examining_______.

A. daily weather maps B. upper air levels

C. satellite reports D. changing fronts

19. At the present time, experiments are being conducted in_____

A. 30-day "outlook" B. controlling storms

C. controlling weather D. determining density of pressure groups

20. Artificial rainmaking has been most successful in the_______.

A. lake area

B. western slope of mountains

C. grass lands

D. windward side of mountains

Who is disabled in China?China is a country with a large number of disabled.Almost 60 mi

Who is disabled in China?

China is a country with a large number of disabled.Almost 60 million people have vision, hearing, speech, limb, intellectual or mental impairments.There is one disabled person in every 20 Chinese, and one out of every five households on average has a disabled family member.

According to nationwide surveys of the disabled, handicapped children under 14 account for 16 percent of the total handicapped population, and they display the greatest need for rehabilitative training as they display the highest recovery rates after early therapy.Those disabled between the ages of 15 and 59 account for 44 percent, but often their disabilities are not very severe.Although they are more or less able to work, they require vocational training, ‘cultural education’ and special employment.

The disabled over 60 years of age account for 40 percent.Many of them become handicapped due to illness or loss of various functions.Some live alone without any income, and therefore their insurance, rehabilitation, and medical needs have become a social issue.

The illiterate and semi-illiterate suffer from limited employment opportunities, and often they become socially handicapped as well.These people, often neglected, pose another social problem.
