6分,满分30分)阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。

1. The Greatest Bazaar in the World You can buy anything in New York. Everything is for sale: Tibetan beads, canned rattlesnake, Irish claddagh rings, lizard-skin cowboy

boots, ponchos, old photograph cylinders, Australian wines, Navaho jewelry, love

potions, tongs for removing toast from a toaster, orange blossom honey, air guns designed to fire coins into the baskets of toll booth, frozen yogurt, dried seaweed, prayer

wheels, wormwood, Iberian hams, polish sausages, paintings that sell for as much as five million dollars, rare books, props from hit plays, the autographs of every president of the USA since George Washington, African masks, lessons in yoga, do-it-yourself harpsichord-assembly kits, "organic" peanut butter.

You name it, and there is a store in the big apple which sells it.

Price-conscious shoppers should remember that there is always a bargain sale going on somewhere in the big apple on the Labor or Memorial day holidays, and on Washington's or Lincoln's birthday,prices at department stores decline. If there are no specials,just take a bus to the lower east side,or Loehmann's in the Bronx, where there are permanent sales and you can get quality goods at vastly reduced prices.

Keep in mind also that most of the things for sale in New York city can also be rented or hired: wedding suits, fur coats, diapers, Rolls Royces, bartenders, automobile

tools, animals, bikes,rug cleaners and ski equipment.

You can, believe it or not, rent an interesting guest to attend your party if you want to enjoy it to the fullest.

(1)As a New Yorker, which of the following cannot be bought?________

A. The luxury car Rolls Royces.

B. Ski equipment.

C. The autograph of Franklin Delano Roosevelt.

D. A person accompanying you to a party..

(2)On what kinds of days are prices in the big apple department stores not marked down?________

A. Labor day.

B. Memorial day.

C. Washington's birthday.

D. Womens' day..

(3)If you want to buy discount goods at any time, which of the following places will you most probably go to?________

2. Kids and science seem to be made for each other!

The basic science is a combination of thought and experiment called the scientific method. It's where you start with an idea, create a way to prove or disprove your idea, and show what you learned based on facts. Learning to follow this process helps you think logically(逻辑地) and carefully. These important thinking skills can be used in many areas of study. To give a child practice with these thinking skills is like giving vitamins(维生

素) to a developing mind.

One of the greatest things we can teach our children is to love learning. Learning science is a great way to do so. Children are easy to be interested in science. Because much of science is hands-on,it attracts most children. Nothing makes a child sit up and take notice like the "WOW!" of a great science showing.

Science opens doors to many subjects at school. Building love for science can be helpful in other areas of study. For example, one cannot love science for very long without becoming good at its language-math! So science encourages children to study math. An interest in science is an interest in how things were once understood compared to how they are understood now. Thus studying science lends itself easily to studying history. And after you do an experiment,you need to write a lab report. Therefore, writing becomes an important part of science.

Science is the basic thing for much of our life. The science of farming shows how our food is produced; biomedical science keeps us healthy; even our beds these days are designed according to scientific facts. We almost eat, sleep and breathe with the help of science! When we prepare the next generation(一代)of voters, creators and policy makers, it is important to make sure they are not only comfortable but also good at science.

(1)What is the text mainly about?________

A. How kids can make use of science.

B. Why science is important.

C. Why kids should learn science.

D. What kids should learn at school..

(2)According to Paragraph 2, what does learning the scientific method mean to kids?________

A. Learning to do experiments.

B. Learning many areas of study.

C. Helping them develop thinking skills.

D. Refusing any ideas that are not logical..

(3)If a child works hard at science at school, he/she________.

A. usually has no time for other subjects

B. is likely to learn many other subjects well

C. is usually bad at such subjects like history

D. usually loses interest in other activities.

(4)Which of the following statements would the author agree with?________

A. Science is too difficult for children.

B. Children usually consider science boring.

C. Science could make children love learning.

D. Children who can't think carefully shouldn't learn science..

3. In the subway station,I notice a black teenage boy waiting for the train,sitting on a railing(栏杆) just in front of a moving escalator(扶梯). It's a hot evening; there is no air in the station. This black kid is just sitting there, settled on the railing,and I'm just standing there about 10 feet away looking for the faraway lights of the oncoming train. Then suddenly a white police officer is asking the kid for identification. The kid turns a little annoyed and asks what he's been bothering about. The officer doesn't explain. The kid pulls out some I.D. and hands it to the officer who looks at it and then barks out a demand for something with an address on it, a driver's license.

Unwillingly, the kid pulls out a second piece of identification. The officer looks at it and tells the kid to come with him. Nothing I have seen or heard explains the officer's strict approach or why the kid is being led away.

I get up to the officer and politely ask what this guy did and where he is taking him. He looks at me like I'm armed and crazy and tells me that it's none of my business and to stay out of this.

"Could I please take down your badge(警徽) number, sir, as I'd like to report all this," I say.

"Take down my badge number and then you show me a piece of identification. What are you, some lawyer? "

I copy down his badge number and then show him my driver's license, asking, "Could you please tell me what this is all for? "

Looking at me over and again asking if I'm a lawyer, he tells me he's taking the kid in for blocking the escalator and me in for "obstructing a police action." Another black man hearing all this asks what's going on and the officer gets very nervous. So I decide to go with him to his office. Then the officer gives his version of what happened and I politely interrupt to explain that the kid was in no way blocking the escalator traffic and that I was in no

way "obstructing a police action", not adding that I thought the way the officer handling the situation was racist and unnecessarily strict.

After this experience in the police station,I'm still wondering whether a well-dressed white man will be faced with a sharp command for identification for sitting on an escalator

railing waiting for a train? If a bystander does want to get involved and inquire about an apparently unfair arrest, is a policeman's only response a second arrest? Will our police officers always be seen by black kids as evils? Is my charge with racism too strong?

(1)What is the black teenager doing at the train station?________

A. He is blocking the escalator.

B. He is escaping the police.

C. He is waiting for the train.

D. He is damaging the escalator..

(2)Why does the author stand out to help the black teenager?________

A. He is a racist.

B. He is not afraid to get involved.

C. He is black.

D. He has a sense of justice..

(3)According to the passage, we can know that________.

A. the black boy doesn't obey the police officer

B. subway stations are good places to hang about

C. the white policeman thinks ill of the black teenager

D. situations like this in the passage will never change.

(4)Which of the following best explain the underlined word in the passage?________ A. Blame. B. Forbid. C. Prevent. D. Defend..

4. Psychologists who study moral judgments have found that when people are faced with moral dilemmas,they tend to respond differently when considering them in a foreign language than when using their native tongue.

In a 2014 paper led by Albert Costa,volunteers were presented with a moral dilemma known as the "trolley problem": imagine that a runaway trolley bus is rushing toward a group of five people standing on the tracks, unable to move. You are next to a switch that can change the trolley to a different set of tracks, therefore saving the five people, but resulting in the death of one who is standing on the side tracks. Do you pull the switch?

Most people agree that they would. But what if the only way to stop the trolley is by pushing a large stranger off a footbridge into its path? People hesitate to say they would do this,even though in both situations,one person is sacrificed to save five. But Costa and his colleagues found that setting the dilemma in a language that volunteers had learned as a foreign tongue dramatically increased their stated willingness to push the sacrificial person off the footbridge,from fewer than 20% of respondents working in their native language to about 50% of those using the foreign one.

Why does it matter whether we judge morality in our native language or a foreign one? According to one explanation, such judgments involve two separate and competing modes of thinking: one of these,a quick "feeling" and the other, careful consideration about the greatest good for the greatest number. When we use a foreign language, we unconsciously sink into the more careful mode simply because the effort of operating in our non-native language reminds our brain to prepare for painstaking activity.

An alternative explanation is that differences arise between native and foreign tongues because our childhood languages are associated with greater emotion than those learned in more academic environment. As a result, moral judgments made in a foreign language are less filled with the emotional reactions that appear when we use a language learned in childhood.

What is a multilingual(多语言的)person's "true" moral self? Is it my moral memories that taught me what it means to be "good"? Or is it the reasoning I'm able to apply when free of such unconscious restrictions? Or perhaps,this research simply indicates what is true for all of us: regardless of how many languages we speak,our moral compass is a combination of the earliest forces that have shaped us and the ways in which we escape them.

(1)In the famous "trolley problem" experiment volunteers are asked to________.

A. change the trolley to a different set of tracks

B. push a large stranger off a footbridge

C. sacrifice one person's life to save another five people

D. get involved in making a moral judgment.

(2)What matters most when we judge morality in a foreign language?________

A. Emotional feelings.

B. Careful consideration.

C. Academic environment.

D. The mode of thinking..

(3)What does the writer think determines a multilingual person's "true" moral self in the last paragraph?________

A. Moral memories.

B. Reasoning.

C. Unconscious restrictions.

D. A combination of more than one factor..

(4)What can we learn from the passage?________

A. Native Spanish speakers with English as their foreign language are sure to push that person off the footbridge.

B. An Italian student may find the story of a morally bad person less wrong when it is told in

English.

C. Faced with the same maths problem, one must make more mistakes in a foreign language than in his native one.

D. Representatives at the UN are supposed to base their decisions more on emotion than on reasoning..

5. Three Steps to a Rewarding Career You see the saying:"Do what you love, love what you do."(1)_______"When it comes to work,it is much easier to focus on earning a paycheck to feed,clothes and provide housing for yourself and your family than it is to examine your purpose and passion." says Julie Jansen, an executive career coach in Stamford,Connecticut.

(1)求E 的方程; (2)设过点P (0,√3),且斜率为k 的直线l 与椭圆E 交于不同的两M 、N ,且|MN |=8√2 7,求k 的值. 【解答】解:(1)由离心率e =c a =√2 2,则a =√2c , 直线AF 的斜率k =0?(?2) c?0=2,则c =1,a =√2,b 2=a 2﹣c 2=1, ∴椭圆E 的方程为 x 2 2 +y 2=1; (2)设直线l :y =kx ?√3,设M (x 1,y 1),N (x 2,y 2), 则{y =kx ?√3 x 22+y 2=1,整理得(1+2k 2)x 2﹣4√3kx +4=0, △=(﹣4√3k )2﹣4×4×(1+2k 2)>0,即k 2>1,∴x 1+x 2= 4√3k 1+2k 2,x 1x 2=41+2k 2, ∴|MN |=2|x 1?x 2|=√1+k 2√(x 1 +x 2 )2 ?4x 1x 2= 4√(+k 2 )(k 2 ?1) 1+2k 2 =8√2 7, 即17k 4﹣32k 2﹣57=0,解得k 2=3或?19 17(舍去), ∴k =±√3, 2.已知双曲线C : x 2a 2 ? y 2b 2 =1(a >0,b >0)与双曲线 x 216 ? y 24 =1有相同的渐近线,且 双曲线C 过点(4,√3). (1)若双曲线C 的左、右焦点分别为F 1,F 2,双曲线C 上有一点P ,使得∠F 1PF 2=60°,求△F 1PF 2的面积; (2)过双曲线C 的右焦点F 2作直线l 与双曲线右支交于A ,B 两点,若△F 1AB 的周长是 403 ,求直线l 的方程. 【解答】解:(1)设双曲线C :x 2 16 ? y 2 4 =λ,把点(4,√3)代入得:λ=1 4, ∴双曲线的方程为 x 24 ?y 2=1. 在△PF 1F 2中,设|PF 1|=m ,|PF 2|=n ,
