MY six-year-old granddaughter, Caitlyn, and I stopped at a cake shop to buy some cakes. As we were going out the door, a young teenage boy was 36 in.
This young man had no hair on the sides of his head and a patch of blue hair on top of it. He had a nose ring, which was 37 to a ring he was wearing in his ear with a 38 . He held a skateboard under one 39 and a basketball under the other.
Caitlyn, who was walking ahead of me, 40 when she saw the teen. I thought he'd 41 her, and she'd frozen 42 the spot. I was 43 . My angel went back to the door and opened it as wide as it would go. Now I was 44 with the young man. I stepped 45 and let him pass. His 46 was a polite "Thank you very much."
On our way back home, I praised Caitlyn for her 47 in holding open the door for the young man. She didn't seem to be troubled by his 48 , but I wanted to 49 . After we talked, it turned out that the person who 50 the talk was me.
The 51 thing Caitlyn noticed about the teen was the fact that his arms were full. He would have had a hard time 52 the door.
I saw the partly shaved head, the strange 53 , the rings and the chain. She saw a person carrying something under each arm and 54 toward a closed door. In future, I hope I can get down to her level and 55 my sight.

第三部分 阅读理解（共两节, 满分40分）
第一节 选择题（共17小题, 满分34分）
阅读下列短文, 从每题所给的A、B、C、D四个选中, 选出最佳选项。
A
Speeding off in a stolen car, the thief thinks he has got a great catch. But he is for an unwelcome surprise. The car is fitted with a remote immobilizer (锁止器), and a radio signal from a control center miles away will ensure that once the thief switches the engine off , he will not be able to start it again .
The idea goes like this. A control box fitted to the car contains a mini-cell phone, a microprocessor and memory, and a GPS satellite positioning receiver. If the car is stolen, a coded cell phone signal will tell the control center to block the vehicle’s engine management system and prevent the engine being restarted.
In the
Modern cars are far tougher to steal, as
their engine management computer won’t allow them to start unless they receive
a unique ID code beamed out by the ignition (点火) key. In
the
But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner’s keys. Any key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system.
If the car travels 100 meters without the driver confirming their ID, the system will send a signal to an operation center that it has been stolen. The hundred meters minimum avoids false alarms due to inaccuracies in the GPS signal.
Staff at the center will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicle’s movements via the car’s GPS unit.
56. What’s the function of the remote immobilizer fitted to a car?
A. To allow the car to lock automatically when stolen.
B. To prevent the car thief from restarting it once it stops.
C. To help the police make a surprise attack on the car thief.
D. To prevent car theft by sending a radio signal to the car owner.
57. By saying “The pattern of vehicle crime has changed” (Lines 1-2, Para.3), Martyn Randall suggests that .
A. self-prepared tools are no longer enough for car theft
B. the thief has to make use of computer technology
C. it takes a longer time for the car thief to do the stealing
D. the thief has lost interest in stealing cars over 10 years old
58. What is essential in making a modern car tougher to steal?
A. A GPS satellite positioning receiver.
B. A special cell phone signal.
C. A unique ID card.
D. a coded ignition key.
59. Why does the tracking system set a 100-metre minimum before sending an alarm to the operation center?
A. To give the driver time to contact the operations center.
B. To allow for possible errors in the GPS system.
C. To keep police informed of the car’s movements.
D. To leave time for the operation center to give an alarm.
60. What will the operation center do first after receiving an alarm?
A. Start the tracking system. B. Locate the missing car.
C. Contact the car owner. D. Block the car engine.
B
A man walks into a doctor’s office. He has a cucumber up his nose, a carrot in his left ear and a banana in his right ear. "What’s the matter with me?" he asks the doctor. The doctor replies, "You’re not eating properly."
This is a popular joke among British
schoolchildren. It reflects Britain’s famous dry and satirical (讽刺的) way of
seeing the funny side of life. This unique sense of humor is often cited as one
of
"The famous British sense of humor has long been our most cherished national characteristic," says the British journalist Leo Mckinstry. "We have valued it above historic military victories and great works of literature, above our rich scenic landscape and our talent for invention."
The British sense of humor differs from other countries because it is generally more negative. When it comes to making the British laugh, there is nothing more effective than a socially inappropriate joke.
Popular British comedy shows such as Fawlty Towers, Blackadder and The Office are full of sarcasm (讽刺), teasing and self-deprecation (自嘲). It reflects the culture where mocking (嘲笑), moaning (诉苦) and ridicule is part of everyday life.
While most Britons don’t take these jokes too seriously, foreigners are often bemused (迷惑) by them. A recent survey found that most foreigners who visited Britain found that the British are "arrogant (傲慢的), unfriendly and have almost no sense of humor."
Do foreigners not understand British humor or are the British just not as funny as they think they are? McKinstry certainly thinks the British are funny. "Accusing the British of having no sense of humor is like telling Rolls-Royce that its cars are down-market," he says.
61. The word "dry" in paragraph 2 means ______.
A. difficult to understand
B. popular among children
C. dull and uninteresting
D. amusing without appearing to be so
62. According to Leo McKinstry, which of the following is valued most by the British?
A. Historic military victories.
B. Great works of literature.
C. Their unique sense of humor.
D. Their rich scenic landscape.
63. British humor has the following characteristics EXCEPT being ______.
A. negative B. arrogant C. satirical D. self-deprecating
64. McKinstry mentioned Rolls-Royce to show that ______.
A. the British have good sense of humor
B. the British humor is difficult for foreigners to understand
C. the British are unfriendly
D. the British are not as funny as they think they are
C
I recently wrote an autobiography in which I recalled many old memories. One of them was from my school days, when our ninth grade teacher, Miss Raber, would pick out words from the Reader’s Digest to test our vocabulary.
Today, more than 45 years later, I always check out “It pays to Enrich your Word Power” first when the Digest comes each month. I am impressed with that idea, word power. Reader’s Digest knows the power that words have to move people -- to entertain, inform, and inspire. The Digest editors know that the big word isn’t always the best word. Take just one example, a Quotable Quote from the February 1985 issue: “Time is a playful thing. It slips quickly and drinks the day like a bowl of milk.”
Seventeen words, only two of them more than one syllable, yet how much they convey! That’s usually how it is with Reader’s Digest. Small and simple can be profound (意义深远).
As
chairman of a foundation to restore the Statue of Liberty, I’ve been making a
lot of speeches lately. I try to keep them fairly short. I use small but vivid
words: words like “hope”, “guts”, “faith”, “dreams”. Those are words that move
people and say so much about the spirit of
Don’t get me wrong. I’m not against using big words, when it is right to do so, but I have also learned that a small word can work a miracle -- if it’s the right word, in the right place, at the right time. It’s a “secret” that I hope I never forget.
65. The passage is mainly about .
A. one of the many old memories
B. using simple words to express profound ideas
C. Reader’s Digest and school speeches
D. how to make effective speeches
66. It seems that Reader’s Digest is a magazine popular with .
A. people of all ages B. teenagers
C. school teachers D. elderly readers
67. The author’s “secret” is .
A. to avoid using big words at any time
B. to use words that have the power to move people
C. to work a miracle by using a small word
D. to use small and simple words where possible
68. According to the author, words that have power can give people .
A. hope, courage, and ideas
B. confidence, determination, and strength
C. pleasure, knowledge, and encouragement
D. humor, information, and power
D
While researchers have long shown that tall
people earn more than their shorter counterparts, it's not only social
discrimination that accounts for this inequality -- tall people are just
smarter than their height-challenged peers, a new study finds.
"As early as age three -- before
schooling has had a chance to play a role -- and throughout childhood, taller
children perform significantly better on cognitive tests," wrote Anne Case
and Christina Paxson of
The findings were based primarily on two
British studies that followed children born in 1958 and 1970, respectively,
through adulthood and a
Other studies have pointed to low self-esteem, better health that accompanies greater height, and social discrimination as culprits(罪犯) for lower pay for shorter people.
But researchers Case and Paxson believe the height advantage in the job world is more than just a question of image.
"As adults, taller individuals are more likely to select into higher paying occupations that require more advanced verbal and numerical skills and greater intelligence, for which they earn handsome returns," they wrote.
For both men and women in the
But the researchers said the differences in performance crop up long before the tall people enter the job force. Prenatal care(产前护理) and the time between birth and the age of 3 are critical periods for determining future cognitive ability and height.
"Prenatal care and prenatal nutrition are just incredibly important, even more so than we already knew," Case said in an interview.
Since the study's data only included
populations in the
And how tall are the researchers?
They are both about 5 feet 8 inches tall, well above the average height of 5 feet 4 inches for American women.
69. What can be learnt from the study of Anne Case and Christina Paxson is that ______ .
A. the reason for lower pay for shorter people is social discrimination
B. taller children perform significantly better on cognitive test
C. tall people earn more than shorter counterparts
D. prenatal care and prenatal nutrition are less important than we already knew
70. Which period is the most important for determining future cognitive ability and height?
A. between age 3 and schooling B. between birth and the age of 3
C. the whole childhood D. between 1958 and 1970
71. The underlined phrase “crop up” in the Eighth Paragraph is closest in meaning to ______.
A. get in B. rise up C. come up D. stand up
72. The best title for this passage would be _______.
A. Tall people earn more than shorter counterparts
B. A study on height and occupational choice
C. The difference between tall people and short people
D. Taller people are smarter

The program started in 1985 as part of a wider initiative(首创精神) called "Arts for Transit." Every year, a group of judges selects musicians from hundreds of applicants. Lydia Bradshaw, who works for the New York City Metropolitan Transit System, says that the music enhances the atmosphere.
