閱讀理解

閱讀下列短文，從每題所給的四個選項(A、B、C和D)中，選出最佳選項。

　　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．

(1)

The meaning of“flustered”in Paragraph 2 is related to________．

[　　]

A．

shame

B．

hate

C．

anger

D．

fear

(2)

Why did the driver of the Firebird suddenly speed down the highway?

[　　]

A．

Because he was racing with another driver on the road．

B．

Because he realized he had to hurry to the accident scene．

C．

Because he thought the police officer wanted to stop him．

D．

Because he wanted to overtake other cars on the shoulder．

(3)

Which of the following statements is true?

[　　]

A．

Someone else was taking care of the injured person．

B．

The Pontiac reached its destination at the accident scene．

C．

Hyde knew where he was going by following the right car．

D．

The policeman was running after a speeder on Highway 40．

(4)

The driver of the Firebird________．

[　　]

A．

took a wrong turn on the way

B．

had some trouble with his car

C．

was stopped by the police officer

D．

paid for the expenses of the accident

(5)

B．

Going My Way?

C．

Fun All the Way?

D．

Help on the Way?

閱讀下列短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項，并在答題卡上將該項涂黑。
A
A university math tutor has discovered the science behind “singledom”, finding that our chances of finding the perfect partner are just 1 in 285,000. Peter Backus, a tutor at the University of Warwick, published his “Why I Don’t Have a Girlfriend” paper after a three-year love drought.
His unconventional study uses a famous math formula called The Drake Equation(德雷克等式), which was first used to estimate the existence of extra-terrestrial(地球以外) life.
The results don't look promising for British singles. 30-year-old Mr. Backus found that out of the 30 million women in the UK, only 26 would be suitable girlfriends for him.
The dull equation takes into account the number of women aged 24 to 34, living in his home city of London, and who are single, meaning his chances of meeting his dream woman on a night out are slim.
The economics expert said: “There are 26 women in London with whom I might have a wonderful relationship. So, on a given night out in London there is a 0.0000034% chance of meeting one of these special people. That’s a 1 in 285,000 chance, so it’s not great.”
The puzzling Drake equation reads: N =" R*" x Fp x Ne x Fi x Fc x L, and helped pioneering scientist Professor Drake to predict that there could be 10,000 civilizations in our galaxy.
Mr. Backus simply replaced the original equation with his own criteria for a dream date, which included the percentage of women likely to find him attractive, and the number of girls aged 24-34 in London. He said: “The research may sound depressing to people looking for love, but the good news for singles is, it’s probably not your fault!”
56. Mr. Backus’ discovery in this passage is mainly concerned about ______.
A. whether there exists life out of our planet
B. the possibility of his being able to find love
C. how to get rid of singledom
D. what math can do to serve our daily life
57. What does Mr. Backus think of the result of his research?
A. Optimistic.     B. Depressing.      C. Unrealistic.     D. Exciting.
58. What can we learn from the first paragraph?
A. Mr. Backus’ major research field is “singledom”.
B. Mr. Backus found a girlfriend three years ago.
C. Mr. Backus’ new thesis will surely be well received.
D. Mr. Backus has been searching for love for long.
59. By “the good news for singles” in the last sentence, Mr. Backus probably mean _____.
A. you don’t have to blame yourself for remaining single
B. maybe the discovery is not reliable at all
C. the result was based on his own criteria
D. there might be more dream date out of London
60. Which of the following statements is true?
A. This passage could be published in a scientific magazine.
B. The passage intends to prove there are other civilizations.
C. The passage writer doesn’t really understand the Drake equation.
D. Most women in London are not suitable for university teachers.
