For him, books were knowledge, and yet, he loved his 43 .What he did in the next few minutes was remarkable. Instead of punishing my brother, instead of 44 or yelling or shouting, he sat down, took the pen from my brother’s hand and then wrote in the book himself, alongside the 45 John had made: “John’s word 1959, aged two. How many times have I looked into your 46 face and into your warm, black eyes looking up at me and thanked God for the one who has now scribbled in my new hymnbook. You have made the 47 sacred（神圣的）as your brothers and sisters give so much to my life.” Wow, I thought: This is the 48 my father is giving?

IV阅读理解（共10小题；每小题2分，满分20分）
阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项，并在答题卡上将该项涂黑。
A
Most shoplifters agree that the January sales offer wonderful opportunities for the hard-working thief. With the shops so crowded and the staff so busy, it does not require any extraordinary talent to help yourself to one or two little things and escape unnoticed. It is known, in the business, as “hoisting”.
But the hoisting game is not what it used to be, even at the height of the sales, shoplifters today never know if they are being watched by one of those evil little balls that hang from the ceilings of so many department stores above the most desirable goods.
As if that was not trouble enough for them, they can now be filmed at work and forced to attend a showing of their performance in court.
Selfridges was the first big
When the balls, called sputniks, first make an appearance in shops, it was widely believed that their only function was to frighten shoplifters. Their somewhat ridiculous appearance, the curious holes and red lights going on and off, certainly make the theory believable.
It did not take long, however, for serious shoplifters to start showing suitable respect. Soon after the equipment was in operation at Selfridges, store detective Chadwick was sitting in the control room watching a woman secretly putting bottles of perfume into her bag.
“As she turned to go,” Chadwick recalled, “she suddenly looked up at the ‘sputnik’ and stopped. She could not possibly have seen that the camera was trained on her because it is completely hidden, but she must have had a feeling that I was looking at her.”
“For a moment she paused, but then she returned to shelves and started putting everything back. When she had finished, she opened her bag towards the camera to show it was empty and hurried out of the store.”
56．The sputniks hanging from the ceiling are intended ________.
A．to watch the most desirable goods
B．to make films that can be used as evidence
C．to frighten shoplifters by their appearance
D．to be used as evidence against shoplifters
57．The case last October was important because _________.
A．the store got the dresses back
B．the equipment was able to frighten shoplifters
C．other shops found out about the equipment
D．the kind of evidence supplied was accepted
58． The woman’s action before leaving the store shows that she _______.
A．was sorry for what she had done
B．didn’t want to take what she had picked up
C．was afraid she would be arrested
D．wanted to prove she had not intended to steal anything
B
Babies are not just passing idle time when they stare goggle-eyed at the television―they are actually learning about the world，U.S. researchers said. Parents may want to limit what their babies see on television，based on the study，said Donna Mumme，assistant professor of psychology at Tufts University in Boston，who led the research. “Children as young as 12 months are making decisions based on the emotional reactions of adults around them，” Mumme said in a statement. “It turns out that they can also use emotional information they pick up from television. This means that adults might want to think twice before they speak in a loud and harsh voice or let a baby see television programs intended for an older person. ”Mumme’s team already knew that babies watch other children and adults for information about the world. A mother urging her baby to eat some “yummy” soup or a brother crying in fear when a dog approaches can influence a baby’s reaction. Mumme’s team tested babies to determine if television has the same influence，showing actors reacting on a videotape to objects such as red spiral letter holder，a blue bumpy ball，and a yellow garden hose attachment. Babies aged 10 months or 12 months were later given the same objects to play with. Ten-month-olds did not seem to be influenced by the videos，but the 1-year-olds were. When the actors acted neutrally or positively to an object，the babies happily played with them. But if the actor had seemed afraid or disgusted，the babies would avoid the object.
59．The underlined word may probably mean______.
A．unpleasant B．cruel C．noisy D．upset
60．Which of the following is Mumme’s conclusion??
A．Small babies should not be allowed to watch television programs.?
B．Adults need to think twice before they act in front of small babies.?
C．TV programs provide small babies with all the information they need. ?
D．One-year-olds can be emotionally influenced by TV programs.?
61． Which of the following may the study lead to according to the researchers??
A．Parents may want to limit what their babies see on television.?
B．Actors may try to behave themselves well in front of babies.?
C．Babies may be allowed to choose what they see on TV.?
D．Scientists may stop ignoring babies’ emotional world. ?
C
How Much to Tip
You’re out to dinner. The food is delicious and the service is fine. You decide to leave a big fat tip: Why? The answer may not be as simple as you think.
Tipping, psychologists have found, is not just about service. Instead, studies have shown that tipping can be affected by psychological reactions to a series of different factors from the waiter’s choice of words, to how they carry themselves while taking orders, to the bill’s total. Even how much waiters remind customers of themselves can determine how much change they pocket by the end of the night.
“Studies before have shown that mimicry(模仿) brings into positive feelings for the mimicker,” wrote Rick van Baren, a social psychology professor. “ These studies show that people who are being mimicked become more generous toward the person who mimics them.”
So Rick van Baren divided 59 waiters into two groups. He requested that half serve with a phrase such as, “Coming up!” Those in the other half were instructed to repeat the orders and preferences back to the customers. Rick van Baren then compared their-take-home. The results were clear---it pays to mimic your customer. The copycat waiters earned almost double the amount of tips to the other group.
Leonard Green and Joel Myerson,
psychologists at
“That’s also a point of tipping,” Green says, “You have to give a little extra to the cab driver for being there to pick you up and something to the waiter for being there to serve you. If they weren’t there, you’d never get any service. So part of the idea of a tip is for just being there.”
62． These studies show that______.
A．tipping can be affected by physical reactions to many different waiter’s factors
B．people who are being mimicked usually tip less to the person who mimics them
C．the mimic waiters can get almost twice as much money as the other group
D．mimicry makes the mimicker feel bad
63． We know from the passage that the writer seems to______.
A．object to Mr Green’s idea about tipping
B．think part of Mr Green’s explanation is reasonable
C．give his generous tip to waiters very often
D．support the opinions of Mr Green and Rick van Baren about tripping
D
Pets are no strangers to the White House. Many of American Presidents have been animal lovers. In recent times, White House pets have been tame dogs and cats. Long ago, however, presidential pets, like our nation itself, were wilder!
In 1806, President Thomas Jefferson lived in the White
House. Passers-by often caught sight of his pet bears. Explorers had discovered
these fierce bears, caught a pair of small ones, and sent them to
By 1825, the bears were long gone from the White House
scene. Now, the building was home to President John Quincy Adams and his
crocodile. The green beast actually belonged to General Lafayette, a French
hero who had helped the
When President Martin Van Buren moved into the White House in 1837, he brought his tigers with him. At first, Van Buren said the tigers were his. The Sultan of Oman had sent the tigers when Van Buren was elected, so Congress argued that the tigers belonged to the American people. A fight over the tigers continued for months. In the end, Congress sent someone to seize the tigers and put them in a zoo.
Twenty years later, President James Buchanan received another valuable gift when he was in his first year in the White House. This time, the King of Siam sent several elephants! Buchanan had no desire to share his building with the big creatures, so he sent them to the zoo. Buchanan did, however, keep another gift ?a pair of birds. They were a fitting symbol of presidential power.
64．What similar political
effect did
A．The pets made them happy and gay.
B．It took them too much time to look after them.
C．It brought about dissatisfaction with them in Congress.
D．It made people believe that they were animal lovers.
65． The passage mainly tells us _______.
A．The president’s bear garden B．Historical American presidents’ pets
C．The White House as a zoo D．American presidents’ favorites
