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．

When Frida Kahlo’s paintings were on show in London，a poet described her paintings as “a ribbon(丝带) around a bomb”．Such comments seem to suggest Kahlo had a big influence on the art world of her time.Sadly，she is actually a_much_bigger_name today than she was during her time.
Born in 1907 in a village near Mexico City，Kahlo suffered from polio(小儿麻痹症) at the age of seven.Her spine(脊柱) became bent as she grew older.Then，in 1925，her back was broken in several places in a schoolbus accident.Throughout the rest of her life，the artist had many operations，but nothing was able to cure the terrible pain in her back.However，the accident had an unexpected side effect.While lying in her bed recovering，Kahlo taught herself to paint.
In 1929，she got married to Diego Rivera，another famous Mexican artist.Rivera’s strong influence on Kahlo’s style can be seen in her early works，but her later works from the 1940s，known today as her best works，show less influence from her husband.
Unfortunately，her works did not attract much attention in the 1930s and 1940s，even in her home country.Her first onewoman show in Mexico was not held until 1953.For more than a decade after her death in 1954，Kahlo’s works remained largely unnoticed by the world，but in the 1970s her works began to gain international fame at last.

It was a village in India.The people were poor.However，they were not unhappy.After all，their forefathers had lived in the same way for centuries.
Then one day，some visitors from the city arrived.They told the villagers there were some people elsewhere who liked to eat frog’s legs.However，they did not have enough frogs of their own，and so they wanted to buy frogs from other places.
This seemed like money for nothing.There were millions of frogs in the fields around，and they were no use to the villagers.All they had to do was catch them.Agreement was reached，and the children were sent into the fields to catch frogs.Every week a truck arrived to collect the catch and hand over the money.For the first time，the people were able to dream of a better future.But the dream didn’t last long.
The change was hardly noticed at first，but it seemed as if the crops were not doing so well.More worrying was that the children fell ill more often，and，there seemed to be more insects around lately.
The villagers decided that they couldn’t just wait to see the crops failing and the children getting weak.They would have to use the money earned to buy pesticides(杀虫剂) and medicines.Soon there was no money left.
Then the people realized what was happening.It was the frog.They hadn’t been useless.They had been doing an important job—eating insects.Now with so many frogs killed，the insects were increasing more rapidly.They were damaging the crops and spreading diseases.
Now，the people are still poor.But in the evenings they sit in the village square and listen to sounds of insects and frogs.These sounds of the night now have a much deeper meaning.

Robots that can chat，find misplaced glasses，draw aeroplanes and play with your children are drawing thousands of visitors’ attention during an expo in Tokyo as Japan adapts to changes in society.
Robots，such as the soundsensitive Chapit，answer simple questions and even joke with people to help the lonely fight loneliness and stay active in old age.
“Many older people in Japan live alone and have no one to talk to，” said Kazuya Kitamura，a representative of the expo organizer.“Communication robots accompany people and don’t mind listening to the same stories over and over again.”
While Chapit，a relatively simple robot，managed to allure a corporate partner，many researchers，such as Kiyoshi Matsumoto，a professor at the University of Tokyo，struggle to interest sponsors for more expensive projects.
Matsumoto’s “Personal Mobility Robot”，equipped with four cameras and a sensor to recognize the user’s centre of gravity，is designed to help the elderly move around without pressing buttons，using joysticks(操纵杆) or rotating(转动) wheels as in traditional wheelchairs.
The robot can also help find misplaced glasses by identifying them with a sensor.
“We have developed a robot that can assist many people，but because of the high cost，we still haven’t found a sponsor，”said Matsumoto，who added that the cost of the machine，if massproduced，would be comparable to that of a car.
“In the current economic environment there are few companies willing to invest in such a costly project，” he said.
Other robots，such as the awardwinning “DiGRO” can support busy parents who have little time to play with their children.
The robot can use the Internet to find a simple image and then draw pictures，keeping children company while their parents work.
Japan has one of the world’s fastestageing societies and the government predicts that by 2050 the proportion of people over 65 will reach 40 percent.The underlined word “allure” in Paragraph 4 can be replaced by ________.
| A．strike | B．exclude |

| B．the robots are of poor design |
| C．the production of robots costs a lot |
| D．the future market is worrying |
It can be inferred from the text that ________.
| A．many children lack love from parents |
| B．robots helpful to the old will be in great demand |
| C．robots are the most useful to children |
| D．robots do better than people in healthcare |
Almost every machine with moving parts has wheels，yet no one knows exactly when the first wheel was invented or what it was used for.We do know，however，that they existed over 5,500 years ago in ancient Asia.
The oldest known transport wheel was discovered in 2002 in Slovenia.It is over 5,100 years old.Evidence suggests that wheels for transport didn’t become popular for a while，though.This could be because animals did a perfectly good job of carrying farming tools and humans around.
But it could also be because of a difficult situation.While wheels need to roll on smooth surfaces，roads with smooth surfaces weren’t going to be constructed until there was plenty of demand for them.Eventually，road surfaces did become smoother，but this difficult situation appeared again a few centuries later.There had been no important changes in wheel and vehicle design before the arrival of modern road design.
In the mid1700s，a Frenchman came up with a new design of road—a base layer(层) of large stones covered with a thin layer of smaller stones.A Scotsman improved on this design in the 1820s and a strong，lasting road surface became a reality.At around the same time，metal hubs (the central part of a wheel)came into being，followed by the pneumatic tyre(充气轮胎) in 1846.Alloy wheels were invented in 1967，sixty years after the appearance of tarmacked roads(柏油路)．As wheel design took off，vehicles got faster and faster.

The inventor of the world wide web，Tim BernersLee，has won an important award which comes with a prize bag of one million euros (￡671,000)．The “Father of the Web” was named as the first winner of the Millennium Technology Prize by the Finnish Technology Award Foundation.He said he had just been “in the right place at the right time” and did not want his photo taken.
In 1991，he came up with a system to organize，link and browse(浏览) Net pages which revolutionized the Internet.The British scientist was knighted(封爵) for his pioneering work in 2003.
Sir Tim created his program while he was at the particle physics institute，Cern，in Geneva.The computer code he came up with let scientists easily share research findings across a computer network.In the early 1990s，it was called the “world wide web，” and is still the basis of the web as we know it.
The famous man never went on to commercialize his work.Instead he worked on expanding the use of the Net as a channel for free expression and cooperation.
“The web is encouraging new types of social networks and opening up new ways for information management and business development.The web has significantly improved many people’s ability to obtain information central to their lives，”said Pekka Tarjanne，chairman of the Millennium Technology Prize award committee.
Just under 80 people from 22 countries were nominated(提名) for the prize for their work in the areas of health，communication，new materials and the environment.
The Millennium Technology Prize was set up by the Finnish Technology Award Foundation，an independent body backed by the public and private money which aims to recognize outstanding creations.
Sir Tim currently heads up the World Wide Web Consortium (W3C) at the Massachusetts Institute of Technology in Boston，where he is now based as an academic.It can be learned from the first two paragraphs that ________.
| A．it is Tim BernersLee that invented the Internet |
| B．no one was able to surf the Net before the world wide web was invented |
| C．the Internet can’t be used so widely without Tim BernersLee’s invention |
| D．the Millennium Technology Prize was set up for Tim BernersLee |
