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. 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 an synoptic picture(气象图) of conditions in the atmosphere at a given time.?

All students of geography should 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 climate 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 outlooks are based on an analysis of the upper air levels.?

With the use of electronic instruments and satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations(气象站).Experiments are also in progress for weather modification studies, although few successful results such as artificial rainmaking have been achieved so far.?

Which is not mentioned in this passage in the following about one characteristic of weather?

A. Fronts. B. Temperature change. C. Wind speed. D. Frost.?

The observation of weather conditions by satellites is advantageous because

_______.

A. it is modern and sophisticated?

B. it used electronic instruments?

C. it enables man to alter the weather?

D. it gives the scientists information not obtained readily otherwise?

The word “interpret” in Paragraph 2 most probably means _______

The map is one of the best tools a man has __ he goes to a new place．

A．whenever	B．whatever
C．wherever	D．however

C
Flags have existed for over 3000 years.The earliest flags were wooden or metal poles topped with a carving.About 2000 years ago pies of fabric were added to some poles for decoration.Over the next 500 years the free-flying part of the flag became more important.
Every country today has its own flag.Many groups and organizations also have a flag which stands for,or symbolizes,the aims of the group.
The flag depicts (描绘)a world map,centered on the north pole.The map is surrounded by an olive(橄榄)wreath(花环)symbolizing peace and co-operation.The flag is blue and white.
8.Flags have been in existence for _________.
A.500 years                     B.over 3000 years
C.about 2000 years              D.between 500 and 2000 years
9.A very old flag is likely to _________.
A.be made of fabric             B.have a map on it
C.have white shapes on it       D.be made of carved wood
10.An olive wreath is used to represent _________.
A.peace         B.purity        C.justice       D.equality

A weather map is an important tool for geographers. A succession of three or four maps presents continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts (气锋) to determine whether an individual pressure aroa is deepening or becoming shallow and whether a front is increasing or decreasing in intensity (强烈).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 summary 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 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 anaiysis of the upper air levels which often set the stage for development of air masses, fronts and storms.

Considerable effort is being exerted today to achieve more accurate weather

predictions, with identifying and tracking storms over regions which have but few meteorological (气象)stations. Extensive experiments are also in progress for weathef modification studies.

C. makes weather prediction easier

D. shows things that would otherwise take hours to describe in a few minutes
