3、4、5、6、7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 became free people,they still experienced discrimination in employment,housing,education,and even in public facilities,such as restroom.

9、10、11、12、13题:By far the most common snake in Britain is the adder. In Scotland, in fact, there are no other snakes at all. The adder is also the only British snake with a poisonous bite. It can be found almost anywhere, but prefers sunny hillsides and rough open country, including high ground. In Ireland there are no snakes at all.
Most people regard snake bites as a fatal misfortune, but not all bites are serious, and very few are fatal. Sometimes attempts at emergency treatment turn out to be more dangerous than the bite itself, with amateurs heroically, but mistakenly, trying do-it-yourself surgery and other unnecessary measures.
All snakes have small teeth, so it follows that all snakes can bite, but only the bite of the adder presents any danger. British snakes are shy animals and are far more frightened of you than you could possibly be of them. The adder will attack only if it feels threatened, as can be happen if you take it by surprise and step on it accidentally or if you try to catch it or pick it up, which it dislikes intensely. If it hears you coming, it will normally get out of the way as quickly as it can, but adders cannot move very rapidly and may attack before moving if you are very close.
The effect of a bite varies considerably. It depends upon several things, one of which is the body-weight of the person bitten. The bigger the person, the less harmful the bite is likely to be, which is why children suffer more seriously from snake bites than adults. A healthy person will also have better resistance against the poison.
Very few people actually die from snake bites in Britain, and though these bites can make some people very ill, there are probably just as many cases of bites having little or no efforts, as there are of serious illness.
41. Adders are most likely to be found _______.
A. in Scotland and nowhere else
B. in wider parts of Britain
C. in shady fields in England
D. on uncultivated land throughout Britain
42. We are told that British snakes are ______.
A. afraid of human beings
B. poisonous including the adder
c. dangerous except the adder
D. friendly towards human beings
43. Which of the followings statements is Not true?
A. The adder is the only poisonous snake in Britain.
B. In Scotland there are no other snakes except the adder.
C. Snake bites seem more dangerous than they actually are.
D. People's attempts at emergency treatment are utterly unnecessary.
44. When will the adder not attack you?
A. when you try to catch it
B. when you are some distance away from it.
C. when you happen to step on it.
D. when you try to pick 
45. If an adder hears you coming, it will usually _______.
A. attack you immediately
B. disappear very quickly
C. want to frighten you
D. move out of the way
