7、8、9、10、11题:T[ornadoes,whirlwinds,and watersprouts are rotating funnel cloud air masses of small diameter.They are differentiated by the intensity of their rotation and by
the surfaces that they traverse.Though tornadoes and whirlwinds both travel over land masses,whirlwinds are atmospheric systems smaller than tornadoes.Watersprouts are tornadoes that form or pass over a water surface.A tornado is a powerful vortex or “twister” whose rotational speeds are estimated to be near 300 miles per hour.The first visible indication of tornado development is usually a funnel cloud.As this funnel dips earthward,it becomes darker because of the debris
that is forced into its intensifying vortex.Some tornadoes give no visible warning until their destruction strikes the unsuspecting victim.Tornadoes often occur in groups,and several twisters sometimes descend from the same cloud base.The forward speed of a tornado is normally 30 to 40 miles per hour.In the short time that it takes to pass,a tornado can cause fantastic destruction.There have been cases reported in which blades of straw were embeded in fence posts.

12、13、14、15、16题:Ironically,in the United States,a country of immigrants,prejudice and discrimination continue to be serious problems.There was often tension between each established group of immigrants and each succeeding group.As each group became more financially successful,and more powerful,they excluded newcomers from full participation in the society.Prejudice and discrimination are part of our history,however,this prejudicial treatment of different groups is nowhere more unjust than with black Americans.
Blacks had distinct disadvantages.For the most part,they came to the “land of opportunity”as slaves and they were not free to keep their heritage and cultural
traditions.Unlike most European immigrants,blacks did not have the protection of a support group;sometimes slaveowners separated members of the same family.
They could not mix easily with the established society either because of their skin color.It was difficult for them to adapt to the American culture.Even after
they became free people,they still experienced discrimination in employment,housing,education,and even in public facilities,such as restroom.
