Chimpanzees, long considered reluctant to share, apparently can display selfless tendencies, revealing one more key way our closest living relatives are like humans, scientists find. These findings could shed light on the evolution of altruism in humans.
Previously, a belief was widely held that human altruism evolved only after humans split from their ape cousins about 6 million years ago. In recent years, however, research has revealed just how much chimpanzees have in common with us. They can hunt with spears, play with dolls and mourn their partners’ death.
"Most of the earlier studies had presented the apes with a complex implement that helped them deliver food to themselves or others, often so complicated that the experiments tested tool skills rather than social tendencies," De Waal told Live Science. "Ours is the first study that uses no such implement at all."
In addition to using complex food-delivery systems, past experiments often placed the chimpanzees so far apart that they might not have realized how their actions benefited others. In these new, simplified experiments, two apes were housed next to each other with a screen through which they could see each other. Then, one chimpanzee had to choose between two differently colored tokens (币) from a bin, one of which represented a pro-social (亲社会的) option, the other a selfish option. The pro-social option would cause both chimpanzees to receive a piece of banana wrapped in paper. The selfish option only rewarded the ape who made the choice.
In a study with seven adult female chimps placed into various pairs, the scientists found all the apes showed a definite preference for the pro-social option. "For me, the most important finding is that like us, chimpanzees take into account the needs and wishes of others," researcher Victoria Horner, said.
The chimpanzees behaved especially altruistically toward partners who either patiently waited or gently reminded them that they were there by drawing attention to themselves. They were less likely to reward partners who pressured through making a fuss, begging persistently or spitting water at them. This is opposite to a long-standing view that the chimpanzees only share food under pressure.The word "altruism" (paragraph 1) is closest in meaning to ______.
| A．selfishness | B．selflessness |
| C．willingness | D．reluctance |
Recent researches are performed with less complicated implements mainly to ______.
| A．show that chimps are only good at using implements |
| B．see whether chimps are willing to share food with others |
| C．find out if chimps are likely to reward partners |
| D．test chimps’ social tendencies instead of tool skills |
Which of the following might be the best title of the passage?
| A．Evolution History of Altruism in Humans |
| B．Similarities between Chimps and Mankind |
| C．Chimps Do Show Selfless Behavior |
| D．Chimps Only Share Food under Pressure |
Many theories regarding the causes of juvenile delinquency (crimes committed by young people) focus either on the individual or on society as the major contributing influence. Theories on the individual suggest that children criminal behavior before they were not sufficiently for previous misbehaviors or that they have learned criminal behavior through interaction with others. Theories focusing on the role of society suggest that children commit crimes in to their failure to rise above their socioeconomic status or as a rejection of middle-class values.
Most theories of juvenile delinquency have focused on children from families, the fact that children from wealthy homes also commit crimes. The latter may commit crimes for lack of adequate control from parents. All , however, are uncertain or unimproved and are of course challenged with criticism.
Changes in the social structure may indirectly juvenile crime rates. For example, changes in the economy that to fewer job opportunities for youth and rising unemployment make gainful employment increasingly difficult to obtain. This results in among youths and may in lead more youths into criminal behavior.
Families have also experienced these years. More families consist of one parent households or two working parents; , children are likely to have less supervision at home than was common in the traditional family . This lack of parental supervision is thought to be an influence on juvenile crime rates. Other noticeable of offensive acts include experience or failure in school, the availability of drugs and alcohol, and the growing phenomenon of child abuse and child neglect. All these conditions tend to increase the of a child committing a criminal act, a direct cause and effect relationship has not yet been established.

With the World Cup always held in the European off-season in June and July, when the tiny nation of Qatar beat out USA Australia, Japan and South Korea, as the venue（地点）of the 2022 World Cup Soccer, there were gasps of surprise from the fans – it was not just because of the size of the competitors, but also the fact that Doha sees an average top temperature of 41 degrees Celsius in June and July with the possibility of top temperatures as high as 50°C.
Since the World Cup cannot be moved to the ‘cooler’ season in January or to a neighboring country with milder weather, Qatar has to figure out a solution to make the game more comfortable. A team of engineering scientists from Qatar University (QU) have taken a more high-tech approach to solving the problem – they've reportedly developed a type of artificial "cloud" designed to float above the World Cup venues and provide fans and players with relief from the blazing sun.
The artificial clouds system was invented by a team led by Dr Saul Abdul Ghani, Head of the Mechanical and Industrial Engineering Department at QU, who told Gulf News that the "clouds" would be made from a lightweight carbon structure carrying a giant envelope of material containing helium（氦）gas. The "cloud" would also feature solar panels on its upper surface to power engines that allow the cloud to be moved via remote control. While the country officials have promised to improve some of the issues with solar-powered stadiums capable of reducing the temperatures inside, to a comfortable 20℃, there is still concern of how the players will be able to function in the practice fields.
The system would initially cost around US$500,000, with prices coming down with commercial scale production. However, since Qatar needs to find a solution, the money is probably to the issue. The bigger question is, will this team of scientists actually be able to conjure up（兑现）something that they have promised? We will all find out in about eleven years!By mentioning “the European off-season”, the author tells us .
| A．why the World Cup is held |

Susan Sontage（1933—2004）was one of the most noticeable figures in the world of literature. For more than 40 years she made it morally necessary to know everything---to read every book worth reading ,to see every movie worth seeing .When she was still in her early 30s, publishing essays in such important magazines as Partisan Review, she appeared as the symbol of American culture life ,trying hard to follow every new development in literature, film and art .With great effort and serious judgement. Sontage walked at the latest edges of world culture.
Seriousness was one of Sontage’s lifelong watchwords(格言), but at a time when the barriers between the well-educated and the poor-educated were obvious, she argued for a true openness to the pleasure of pop culture. In “Notes Camp”, the 1964 essay that first made her name ,she explained what was then a little-known set of difficult understandings, through which she could not have been more famous .“Notes on Camp”. she wrote, represents “a victory of ‘form’ over ‘content’, ‘beauty’ over ‘morals’”.
By conviction（信念）she was a sensualist（感觉论者）, but by nature she was a moralist （伦理学者）,and in the works she published in the 1970s and 1980s , it was the latter side of her that came forward. In illness as Metaphor —published in 1978, after she suffered cancer—she argued against the idea that cancer was somehow a special problem of repressed personalities（被压抑的性格）, a concept that effectively blamed the victim for the disease. In fact , re-examining old positions was her life long habit.
In America, her story of a 19th century Polish actress who set up a perfect society in California, won the National Book Award in 2000. But it was as a tireless all-purpose cultural view that she made her lasting fame. “Sometimes,” she once said，“I feel that, in the end, all I am really defending is the idea of seriousness, of true seriousness.” And in the end, she made us take it seriously too.The underlined sentence in paragraph 1 means Sontag_________.

Every human being has a unique arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.
The ridge（脊状）structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.
Finger-prints can be made very easily with printer's ink. They can be recorded easily. With special methods, identification can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident.
When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to "develop" them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.Scientists and experts have proved that the pattern of a human being's finger skin__ ___
| A．is similar to his mother's |
| B．is valuable to himself only |
| C．is like that of others with the same type of blood. |
| D．is different from that of all others |
If your fingers are wounded by knife, fire or other means, the structure of skin will____.
| A．be changed partly |
| B．be replaced by a different one |
| C．be the same when the wound is recovered |
| D．become ugly |
Some criminals remove their own finger-prints by ____.
| A．using printer's ink |
| B．injuring the inner skin |
| C．damaging the outer skin |
| D．damaging the color |

| A．is complicated but reliable |
| B．is simple and not expensive |
| C．is expensive but easy to do |
| D．can bring a lot of money |
It is ________for a criminal to deny his crime when finger-prints are used to identify him.
