People have long debated the essence（本质）of human nature．Some people think humans are
born good．In San Zi Jing（Three Chara~er Classic），a Chinese children’s educational book from
the 13th century, we read：“Men at birth are naturally good．Their natures are similar, their habits
become different．’’
Yet some philosophers disagree with this．They think men are born selfish and vicious（恶的）．
For example，Thomas Hobbes，the 1 7th century English philosopher argued that men are born self-
interested and with a liking for war．
Over the centuries，different philosophers have argued their cases．Now the results of a new
study，which contrasts the behavior of very young children and young chimpanzees（黑猩猩）
suggests that human beings are born sociable and helpful to others，according to a New York Times
report．
“Of course every animal must to some extent be selfish to survive．But the biologists also see
in humans a natural willingness to help．”The New York Times science reporter Nicholas Wade writes．
Wade quotes a book published in October by American psychologist Michael Tomasello．
Tomasello writes：“When infants（婴儿）18 months old see an unrelated adult whose hands are
full and who needs help opening a door or picking up a dropped clothespin，they will immediately
help．The helping behavior seems to be innate because it appears so early and before many parents
start teaching children the rules of polite behavior．’’
Tomasello finds that this behavior is not the result of an incentive（动机）of a
reward，suggesting training does not influence it．And it seems to happen across cultures，with their different timetables for teaching social rules．For these reasons，Tomamsello concluded that helping is natural，not something taught by parents or culture．
And it seems that infants cannot only help in practical ways，it can also help with information，
Tomasello writes．From the age of 1 2 months they will point at objects thin all adult pretends to
have lost．Chimpanzees，by contrast，never point at things for each other, and when they point for
people．it seems to be as a command to go fetch something rather than to share information．
49．What is the article mainly about?
A．The behavior of young children．
B．Former philosophies about human nature.
C．The difference between babies and baby chimpanzees.
D．A new study of human nature．
50．According to Michael Tomasello, human beings are born .
A．similar to chimpanzees in nature B．selfish and Vicious
C．sociable and helpful D．with a liking for war
51．Of all the following， has a negative attitude towards human nature.
A．Three Character B．Thomas Hobbes
C．Nicholas Wade D．Michael Tomasello
52．According to the study，it's safe to say that .
A．human beings are not selfish
B．children like to help others when they get a reward
C．different countries teach social rules at different times
D．children tend to be helpful if they are taught early
“It is one of the few bright spots in the Chinese economy，” says Zeng Ming. He is talking about ecommerce. Mr. Zeng, the chief strategy officer for Alibaba, a giant Chinese Internet firm, predicts that digital transactions on his firm's platforms will top 1 trillion yuan($159 billion) this year—more than Amazon's and eBay's combined. That is a bold claim, but consider what happened on Singles Day.
Invented a few years ago by students and seized upon by digital marketers, this festival for lonely hearts falls annually on the 11th day of the 11th month(since 1 is the loneliest number). It is like St Valentine's Day, only worse. Singletons show each other with tender gifts: a barrage of pearls; a storm of sweets.
This November 11th they spent a surprising 19 billion yuan on Alibaba's online platforms—a fourfold increase on a year ago, and more than double what Americans spent online last Cyber Monday(the Monday after Thanksgiving, when retailers urge Americans to shop online). About 100 million purchases were logged, accounting for 80% of the packages shipped that day. Couriers(快递员) were buried in parcels.
So life is good for China's etailers. Then? Not exactly. The number of digital marketers is increasing and online sales are booming. Consumers are enjoying lower prices, better service and more variety. The problem? The pressure on profits in Chinese ecommerce is worse than in America, reckons Elinor Leung of CLSA, a broker. “Almost no one makes money，” she says.
The fiercest battles are being fought between online retailers and their bricksandmortar(实体的) rivals. Dangdang, a firm that resembles Amazon, and 360buy, another online retailer, have cut prices fiercely. Tencent, a cashrich online giant known for its instantmessaging software, is splashing out to win market share. 360buy has also just raised $400 millon from investors to do the same. But it is unclear how much longer such firms can burn through capital.What's the best title of this passage?

A father with Parkinson's disease was arrested as he watched the Olympic cycling road race because he failed to smile or look as if he was enjoying himself.
Mark Worsfold, a martial arts trainer and former soldier, claims that he was thrown to the floor and handcuffed just as cyclists passed by. His worried wife Nicola only found out he was being held after she reported him missing when he did not turn up for their daughter's ninth birthday party. The 54yearold man had his fingerprints, DNA and mugshot taken before being questioned about why he did not appear to be enjoying the event on July 28. Police said Mr. Worsfold, who was held for over five hours, was arrested because of his manner，his state of dress and his being too near to the course. A spokesman added that the arrest was necessary to avoid a breach(破坏) of the peace because he was standing near a group of protesters(抗议者)．
But Mr. Worsfold, who was diagnosed with Parkinson's disease in 2010, said that one of the symptoms of the disease is muscle rigidity, which can cause his face to become expressionless. “I was sitting minding my own business”， he told a local newspaper. “Before I knew anything the police grabbed me off this sevenfoot wall, threw me to the floor and handcuffed me, so all I saw of the cycle race was between the feet of people from the pavement. It could have been done better. I was arrested for not smiling. I have Parkinson's disease.”
Mr. Worsfold has since asked for a letter of not being guilty from police. The officers who made the arrest have apologized to him.Which word can be used to replace the underlined word “mugshot” in the second paragraph?
| A．Clothes. | B．Photos. | C．Measures. | D．Tools. |
Which statement is TRUE according to the passage?
| A．Worsfold's wife was immediately informed of his being arrested by the police. |
| B．Worsfold was arrested because he was extremely dangerous. |
| C．Worsfold enjoyed the cycle race though he saw it between the feet of people from the pavement. |
| D．Worsfold was arrested because of his clothes as well as his facial expression. |
What can we infer from the passage?
| A．The officers must have been punished for Worsfold's arrest. |
| B．Worsfold has an expressionless face and probably looks strong. |
| C．The officers apologized to Worsfold after one day's arrest. |
| D．Worsfold was diagnosed with Parkinson's disease four years ago. |

For many of us, a little time with our smartphones or iPads before sleep is the highlight of the night. But would you still think it is relaxing if you knew that it damages or destroys your sleep? Scientists say that's exactly what it does.
In ancient times, when there were no lamps, telephones or smartphones, the sun was the main source of light. When the sun went down, our brains took that as a signal to start producing melatonin(褪黑素), a chemical that helps us sleep.
However, a healthy amount of melatonin can only be produced in complete darkness.Any light in your bedroom—even the one on the alarm clock or the charging indicator on your cellphone—could disturb the process, not to mention something as bright as smartphone and iPad screens. We tend to hold these much closer than a television or laptop, which allows them to shoot far more light straight into our eyes.
“This is particularly worrisome in populations such as young adults and adolescents, who already tend to be night_owls，” said researcher Brittany Wood at Rensselaer Polytechnic Institute.“Lack of sleep among teens is leading to depression, selfharm, low concentration and poor performance at school，” she added.
While all lights are the enemy of sleep, not all colors of light have the same effect. Our eyes are particularly sensitive to blue light, which is common during the day. Most of the light coming from electronic screens is blue light and it fools our brain into thinking it's still daytime. By contrast, orange or red light has less influence on melatonin production, because our brains recognize it as a signal that the day is ending, according to The Telegraph.
Asking yourself to keep your hands off your smartphone before bedtime might seem unreasonable, but you should at least remember to dim the screen or hold it farther away from your eyes. You could also wear a pair of orange sunglasses that take away the harmful blue light.According to the passage, we can know ________.
| A．it's a good habit to play with smartphones or iPads late into night |
| B．scientists suggest we should avoid using smartphones or iPads |
| C．darkness makes a great impact on the amount of melatonin |
| D．the sun was the only source of light in ancient times |
Which of the following is TRUE according to the passage?
| A．The darker it is, the more melatonin will be produced. |
| B．The lighter it is, the more melatonin will be produced. |
| C．The more melatonin you have, the worse you'll sleep. |
| D．The more electrical equipment you have, the more melatonin will be produced. |
The underlined part in Paragraph 4 refers to those ________.
| A．who are young adults or adolescents |
| B．who don't perform well in school |
| C．who are addicted to a television or laptop |
| D．who are short of sleep at night and perform poorly in daily life |
In the writer's opinion, which is a correct suggestion?
| A．You should go to bed when the sun goes down. |
| B．You should use an orange or red light electronic screen. |
| C．You should wear a pair of blue sunglasses when sleeping. |
| D．You should avoid blue light as possible as you can before bedtime. |
One might expect that the evergrowing demands of the tourist trade would bring nothing but good for the countries that receive the holidaymakers. Indeed, a rosy picture is painted for the longterm future of the holiday industry. Every month sees the building of a new hotel somewhere. And every month another rockbound Pacific island is advertised as the ‘last paradise(天堂) on earth’．
However, the scale and speed of this growth seem set to destroy the very things tourists want to enjoy. In those countries where there was a rush to make quick money out of seaside holidays, overcrowded beaches and the concrete jungles of endless hotels have begun to lose their appeal.
Those countries with little experience of tourism can suffer most. In recent years, Nepal set out to attract foreign visitors to fund developments in health and education. Its forests, full of wildlife and rare flowers, were offered to tourists as one more untouched paradise. In fact, the nature all too soon felt the effects of thousands of holidaymakers traveling through the forest land. Ancient tracks became major routes for the walkers, with the consequent exploitation of precious trees and plants.
Not only can the environment of a country suffer from the sudden growth of tourism. The people as well rapidly feel its effects. Farmland makes way for hotels, roads and airports; the old way of life goes. The onetime farmer is now the servant of some multinational organization; he is no longer his own master. Once it was his back that bore the pain; now it is his smile that is exploited. No doubt he wonders whether he wasn't happier in his village working his own land.
Thankfully, the tourist industry is waking up to the responsibilities it has towards those countries that receive its customers. The protection of wildlife and the creation of national parks go hand in hand with tourist development and in fact obtain financial support from tourist companies. At the same time, tourists are being encouraged to respect not only the countryside they visit but also its people.
The way tourism is handled in the next ten years will decide its fate and that of the countries we all want to visit. Their needs and problems are more important than those of the tourist companies. Increased understanding in planning worldwide tourism can preserve the market for these companies. If not, in a few years' time the very things that attract tourists now may well have been destroyed.What does the author indicate in the last sentence of Paragraph 1?
| A．The Pacific island is a paradise. |
| B．The Pacific island is worth visiting. |
| C．The advertisement is not convincing. |
| D．The advertisement is not impressive. |
The example of Nepal is used to suggest ________.
| A．its natural resources are untouched |
| B．its forests are exploited for farmland |
| C．it develops well in health and education |
| D．it suffers from the heavy flow of tourists |
What can we learn about the farmers from Paragraph 4?
| A．They are happy to work their own lands. |
| B．They have to please the tourists for a living. |
| C．They have to struggle for their independence. |
| D．They are proud of working in multinational organizations. |
Which of the following determines the future of tourism?
| A．The number of tourists. |
| B．The improvement of services. |
| C．The promotion of new products. |
| D．The management of tourism. |
The author's attitude towards the development of the tourist industry is ________.
| A．optimistic | B．doubtful |
| C．objective | D．negative |
