5.It seems that some people go out of their way to get into trouble.That's more or less what happened the night that Nashville Police Officer Floyd Hyde was on duty.
"I was on the way to a personal-inj ury accident in West Nashville.As I got onto Highway 40,blue lights and sirens(警笛)going,I fell in behind a gold Pontiac Firebird that suddenly seemed to take off quickly down the highway.The driver somehow flustered at the sight of me.He was going more than a hundred miles an hour and began passing cars on the shoulder."
But Hyde couldn't go after him.Taking care of injured people is always more important than worrying about speeders,so the officer had to stay on his way to the accident.But he did try to keep the Fi rebird in sight as he drove,hoping another nearby unit would be able to step in and stop the speeding car.As it.turned out,keeping the Firebird in sight was not that difficult.Every turn the Pontiac made was the very turn the officer needed to get to the accident scene.
Hyde followed the Pontiac all the way to his destination.At that point he found another unit had already arrived at the accident scene.His help wasn't needed.Now he was free to try to stop the driver of the Firebird,who by this time had developed something new to panic about.
"Just about that time,"Hyde says,"I saw fire coming out from under that car,with blue smoke and oil going everywhere.He'd blown his engine.Now he had to stop."
"After I arrested him,I asked him why he was running.He told me he didn't have a driver's license."
That accident cost the driver of the Firehird plenty-a thousand dollars for the new engine-not to mention the charges for driving without a license,attempting to run away,and dangerous driving.
 
66.The meaning of"flustered"in Paragraph 2 is related toD.
A.shame        B.hate    C.anger            D.fear
67.Why did the driver of the Firebird suddenly speed down the highway?C
A.Because he was racing with another driver on the road.
B.Because he realized he had to hurry to the accident scene.

D.Because he wanted to overtake other cars on the shoulder.

B.Memories from gift giving
C.Moments and events for gift giving
D.Various functions of gift giving
E.Gift giving as a wasteful practice
F.Gift giving as a two-way social activity
Gift Giving

61.C
There are many occasions(场合) for giving gifts in modern industrialized societies:birthdays,naming ceremonies,weddings,anniversaries,New Year,It is common to give gifts on many of these celebrations in western cultures.In addition,special events,such as one's first day of school or graduation from university,often require gift fiving.
62.F
What is happening when we give gifts?Most important,we are exchanging gifts.If someone gives me a gift for my birthday,I know that I am usually expected to give one on his or her next birthday.A gift builds up or confirms a social obligation(义务).
63.D
Gifts tighten personal relationships and provide a means of communication between loved ones.People say that a gift lets the recipient(接受者) know we are thinking of them,and that we want to make the person"feel special."We want people to feel wanted,to feel part of our social or family group.We give presents to say"I'm sorry."Sometimes it is difficult for us to find a present that someone will like.Sometimes we give things that we like or would feel comfortable with.In all these cases,the gifts are sending out messages-often very expressive ones.
64.B
People tend to talk about presents in a fairly loving way.A woman whose mother had died years ago described the many gifts around her house.These were gifts that her mother had given her over the years:"I appreciate these,and they mean something to me,"the woman said,"because I remember the occasions they were given on,and that they were from my mother,and the relationship we've had."The gifts remain and keep the relationship alive in mind.This woman felt the same way about the gifts she gave to others.She hoped that the recipients would look at here gifts in years to come and remember her.
65.A
Emotions(情感)like these suggest that a positive spirit still lies behind gift giving.They prove that the anthropologist Claude Levi-Strauss was wrong to say that modern western gift giving is highly wasteful.Studies in Canada and elsewhere have also shown that this is not the case.Each gift is unique even if so many are given.The emotional benefit for those who exchange gifts is the very reason for the tradition to continue.
