8.Are some people born clever,and others born stupid?Or is intelligence developed by our environment and our experience?Strangely enough,the answer to these questions is yes.To some extent our intelligence is given to us at birth,and no amount of education can make a genius out of a child born with low intelligence.On the other hand,a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings.While the limits of a person's intelligence are fixed at birth,whether or not he reaches those limits will depend on his environment.This view,now held by most experts,can be supported in a number of ways.
It is easy to show that intelligence is to some extent something we are born with.The closer the blood relationship between two people,the closer they are likely to be in intelligence.Thus if we take two unrelated people at ran dom(随机地) from population,it is likely that their degrees of intelligence will be completely different.If,on the other hand,we take two identical twins,they will very likely be as intelligent as each other.Relations like brothers and sisters,parents and children,usually have similar intelligence,and this clearly suggests that intelligence depends on birth.
Imagine now that we take two identical twins and put them in different environments.We might send one,for example,to a university and the other to a factory where the work is boring.We would soon find differences in intelligence developing,and this indicates that environment as well as birth plays a part.This conclusion is also suggested by the fact that people who live in close contact with each other,but who are not related at all are likely to have similar degrees of intelligence.
25.Which best describes the writer's point in Para.1?C
A.Intelligence is given at birth.
B.Intelligence is developed by the environment.
C.Intelligence is fixed at birth,but is developed by the environment.
D.Some people are born clever and others born stupid.
26.It is suggested in this passage thatA.
A.close relations usually have similar intelligence
B.unrelated people are not likely to have similar intelligence
C.the closer the blood relationship between people,the more different they are likely to be    in intelligence
D.people who live in close contact with each other are not likely to have similar degrees of intelligence
27.The example of the twins going to a university and to a factory separately showsB.
A.the importance of their intelligence     
B.the effect of environment on intelligence
C.the importance of their positions        
D.the part that birth plays
28.The best title for this article would be"A".
A.On Intelligence                      
B.What Intelligence Means
C.Born with Intelligence                   
D.Environment Decides Intelligence.

12.Elvis lives.At least he does today,in the hearts of tens of thousands showing their love for the King on the 25th anniversary(纪念日) of his death.Refusing to let go of fond memories,fans are once again flooding to Graceland,Elvis's house.This annual event is informally known as"Dead Elvis Week",an almost religious journey in memory of Elvis's death on August 16,1977.
Feeling like a cross between an Easter night and Mardi Gras,the week of sadness is hardly a sad affair.In fact,it includes all kinds of parties,concerts,and memorials.The highlight,however,is a candlelight night that more than 10,000fans from all over the world took part in.In twos and threes,they walk up to the small poolside garden where Elvis is buried."The King of Rock‘n'Roll"may be dead,but for these devotees,he is never truly gone.
Elvis Aaron Presley wasn't born a king.As a matter of fact,he grew up dirt-poor in rural Tennessee.Legend(传奇) has it that Elvis was working as a truck driver in Memphis when he made his first recording:a late birthday gift for his mother.Later,when the owner of Sun Records,Sam Phillips,heard Elvis's wonderful voice,he thought he had finally found what he had been looking for-a white man who sounded black.Phillips boasted(夸口) that with Elvis on his label,he would make a million dollars.
Early Sun recordings had Elvis on songs and guitar,supported by another guitar and a stand-up bass.He was playing the kind of material he would one day become famous for:blues and country songs.It was a long way from the white jumpsuits and Las Vegas-style concerts everyone now connects with Elvis.But those early recordings helped what the world now knows as rock‘n'roll come into being.
21.When did the author write the passage above according to the passage?B
A.In 1977.
B.In 2002.
C.Between an Easter night and Mardi Gras.
D.Not mentioned.
22.Which of the following is NOT included in"Dead Elvis Week"?B
A.Parties.
B.A parade.
C.Concerts.
D.A candlelight night.
23.What can be inferred from the underlined part in Paragraph 3?C
A.Elvis was a white man who looked like a black one.
B.Sam Phillips didn't manage to find what he had been looking for.
C.In some way,the black then had a greater gift for singing than the white.
D.Sam Phillips had been seeking a white man who acted like a black.
24.What is the BEST title of the passage?C
A.Elvis Aaron Presley.
B.Dead Elvis Week.
C.The King of Rock‘n'Roll.
D.The Origin of Rock‘n'Roll.
