Take a look at the following list of numbers: 4, 8, 5, 3, 7, 9, 6. Read them loud. Now look away and spend 20 seconds memorizing them in order before saying them out loud again. If you speak English, you have about a 50% chance of remembering those perfectly. If you are Chinese, though, you’re almost certain to get it right every time. Why is that? Because we most easily memorize whatever we can say or read within a two-second period. And unlike English, the Chinese language allows them to fit all those seven numbers into two seconds.

That example comes from Stanislas Dahaene’s book The Number Sense. As Dahaene explains: Chinese number words are remarkably brief. Most of them can be spoken out in less than one-quarter of a second (for instance, 4 is “si” and 7 “qi”). Their English pronunciations are longer. The memory gap between English and Chinese apparently is entirely due to this difference in length.

It turns out that there is also a big difference in how number-naming systems in Western and Asian languages are constructed. In English, we say fourteen, sixteen, seventeen, eighteen and nineteen, so one might expect that we would also say oneteen, twoteen, threeteen, and fiveteen. But we don’t. We use a different form: eleven, twelve, thirteen and fifteen. For numbers above 20, we put the “decade” first and the unit number second (twenty-one, twenty-two), while for the teens, we do it the other way around (fourteen, seventeen, eighteen). The number system in English is highly irregular. Not so in China, Japan, and Korea. They have a logical counting system. Eleven is ten-one. Twelve is ten-two. Twenty-four is two-tens-four and so on.

That difference means that Asian children learn to count much faster than American children. Four-year-old Chinese children can count, on average, to 40. American children at that age can count only to 15. By the age of five, in other words, American children are already a year behind their Asian friends in the most fundamental of math skills.

The regularity of their number system also means that Asian children can perform basic functions, such as addition, far more easily. Ask an English-speaking seven-year-old to add thirty-seven plus twenty-two in her head, and she has to change the words to numbers (37+22). Only then can she do the math: 2 plus 7 is 9 and 30 and 20 is 50, which makes 59. Ask an Asian child to add three-tens-seven and two-tens-two, and then the necessary equation(等式) is right there, in the sentence. No number translation is necessary: it’s five-tens-nine.

When it comes to math, in other words, Asians have a built-in advantage. For years, students from China, South Korea, and Japan --- outperformed their Western classmates at mathematics, and the typical assumption is that it has something to do with a kind of Asian talent for math. The differences between the number systems in the East and the West suggest something very different --- that being good at math may also be rooted in a group’s culture.

What does the passage mainly talk about?

A. The Asian number-naming system helps grasp advanced math skills better.

B. Western culture fail to provide their children with adequate number knowledge.

C. Children in Western countries have to learn by heart the learning things.

D. Asian children’s advantage in math may be sourced from their culture.

What makes a Chinese easier to remember a list of numbers than an American?

A. Their understanding of numbers.

B. Their mother tongue.

C. Their math education.

D. Their different IQ.

Asian children can reach answers in basic math functions more quickly because ____________.

A. they pronounce the numbers in a shorter period

B. they practice math from an early age

C. English speaking children translate language into numbers first

D. American children can only count to 15 at the age of four

As the sound of footsteps behind her grew louder, she quickened her pace. She didn’t want to turn around as the memory of that morning’s newspaper headline made her afraid of what she would see: “City Killer Claims Fourth Victim.”

“Why did I stop for a few drinks in the bar after work?” she thought to herself. Now it was dark and the streets deserted. She was alone and a sitting duck.

She felt as if she was walking in the rain. Her clothes were damp from nervous sweat and as each short hot breath hit the night air, it turned to steam, coating her glasses in a thin film so all she saw seemed covered in fog.

The footsteps were closer now. She needed to get off this street. Her eyes began a useless search for an open store or lighted window. Passing a small lane she looked through, for a possible escape route. But the lane was a dead - end and she laughed to herself at the irony ( 具有讽刺意味的事 ).

The sound of a car behind her turning onto the street interrupted her self – pity. Escape was at hand. But as she was about to throw herself onto the road and shout for the car to stop, the car’s headlights cast a shadow that paralyzed ( 使瘫痪 ) her with terror.

It was the footsteps’ owner. The figure was huge and in its raised arm it held what looked like a lead-pipe, no doubt the one that was about to claim victim number five.

The shadow dissolved as the car passed by and disappeared into the distance. She felt a hand on her shoulder. It was all happening as if in slow – motion. She was waiting for her life to flash before her eyes like all those novels said it would – but it didn’t. The only thing she thought of was her dear husband. She recalled phoning him from work that very afternoon and joking about, of all things, the city killer. It was a night full of ironies.

There was a voice talking to her now but she was lost in thoughts of her fate and didn’t respond. The hand then began turning her around. It was surprisingly gentle given what was about to come. She allowed it to guide her without resistance ( 抗拒 ).

She looked up. She recognized the face, but she didn’t know from where. Its mouth was still talking to her but she couldn’t understand. Then she remembered. The face belonged to the foreign looking man who had served her at the bar. She looked down to his hand and saw in it not a lead – pipe but a rolled up copy of a work report she had been correcting in the bar as she drank.

His words suddenly started to register in her brain and she could hear him. “Miss, Miss. Are you OK? You left this in the bar and it looked important so I thought I’d better give it to you.”

71. The woman was feeling nervous because        .

A. she had left her report in the bar

B. there was a killer in the city

C. she was being followed by someone

D. the streets were dark and empty

72. The underlined expression “a sitting duck” (paragraph 2) is closest in meaning to “        ”.

A. an easy target              B. a frightened person

C. a foolish animal            D. a still position

73. What is the correct order of events that happened to the woman on the day of the story?

a. She went for a drink in a bar.       b. She corrected the report.

c. She heard loud footsteps.    d. She read the newspaper.

e. She called her husband.       f. She felt a hand on her shoulder.

A. d,c,a,e,b,f    B. c,d,a,e,f,b    C. d,a,b,e,c,f    D. d,e,a,b,c,f

74. Why did the woman laugh when she looked into the lane?

A. She was excited because she thought it may be a way to escape.

B. She felt bitter because she had no chance to escape.

C. She was becoming more and more nervous.

D. She realized that she was behaving foolishly.

75. Which of the following can be inferred from the passage?

A. It was raining when she left the bar.

B. The woman had felt nervous about the city killer for days.

C. The temperature was very low that evening.

D. The woman was behaving unreasonably.
