The IQ test has been eclipsed in turn. Most people studying intelligence and creativity in the new millennium now prefer a broader definition, using a multifaceted approach where talents in many areas are recognized rather than purely concentrating on academic achievement. If we are therefore assuming that talented, creative or gifted individuals may need to be assessed across a range of abilities, does this mean intelligence can run in families as a genetic or inherited tendency？ Mental dysfunction such as schizophrenia(精神分裂症)-- can, so is an efficient mental capacity passed on from parent to child？
Animal experiments throw some light on this question, and 'on the whole area of whether it is genetics, the environment or a combination of the two that allows for intelligence and creative ability. Different strains of rats show great differences in intelligence or 'rat reasoning'. If these are brought up in normal Conditions and then run through a maze to reach a food goal, the 'bright' strain make far fewer wrong turns that the 'dull' ones. But if the environment is made dull and boring the number of errors becomes equal. Return the rats to an exciting maze and the discrepancy returns as before -- but is much smaller. In other words, a dull rat in a stimulating environment will almost do as well as a bright rat who is bored in a normal one. This principle applies to humans too -- someone may be born with inborn intelligence, but their environment probably has the final say over whether they become creative or even a genius.
Evidence now exists that most young children, if given enough opportunities and encouragement, are able to achieve significant and sustainable levels of ~academic or sporting prowess. Bright or creative children are often physically very active at the same time, and so may receive more parental attention as a result almost by default -- in order to ensure their safety. They may also talk earlier, and this, in turn, breeds parental interest. This can sometimes cause problems with other siblings(兄弟姊妹)who may feel jealous even though they themselves may be bright. Their creative talents may be undervalued and so never come to fruition(实现). Two themes seem to run through famously creative families as a result. The first is that' the parents were able to identify the talents of each child, and nurture and encourage these accordingly but in an even-handed manner. Individual differences were encouraged, and friendly sibling rivalry was not seen as a particular problem. If the father is, say, a famous actor, there is no undue pressure for his children to follow him onto the boards, but instead their chosen interests are encouraged. There need not even by any obvious talent in such a family since there always needs to be someone who sets the family career in motion, as in the case of the Sheen acting dynasty.
Martin Sheen was the seventh of ten children born to a Spanish immigrant father and an Irish mother. Despite intense parental disapproval he turned his back on entrance exams to university and borrowed cash from a local priest to start a fledgling(乳臭小儿)acting career. His acting successes in films such as Badlands and Apocalypse Now made him one of the most highly-regarded actors of the 1970S. Three sons -- Emilio Estevez,' Ramon Estevez a

The Sky's Limit
Air travel is a rapidly growing source of greenhouse gases. But it is also an indispensable way of travel.
The new A380
The double-decker A380, the biggest airliner the world has seen, landed at Heathrow last month to test whether London's main airport could handle the new 550-seater, due to enter commercial service at the end of this year. It was a proud moment for Britain's Rolls-Royce, the makers of the aircraft's Trent 900 engines. Rolls-Royce says the four Trents on the A380 are as clean and efficient as any jet engine, and produce "as much power as 3,500 family cars". A simple calculation shows that the equivalent of more than six cars is needed to fly each passenger.
Take the calculation further: flying a fully laden A380 is, in terms of energy, like a 14km (nine-mile) queue of traffic on the road below. And that is just one aircraft. In 20 years, Airbus reckons, 1,500 such planes will be in the air. By then, the total number of airliners is expected to have doubled, to 22,000. The huge airplane alone would be pumping out carbon dioxide (CO2) at the same rate as 5 million cars.
That may not seem much compared with the 60 million vehicles that pour off assembly lines every year—or the 1 billion vehicles already on the world's roads. But whereas cars are used roughly for about an hour or so a day, jet airliners are on the move for at least 10 hours a day. And they burn tax-free, highoctane (高能量的) fuel, which dumps hundreds of millions of tonnes of CO2 into the most sensitive part of the atmosphere.
Aviation is a relatively small source of the emissions blamed for global warming, but its share is growing the fastest. The evidence is strong. As a result, aviation is increasingly attracting the attention of environmentalists and politicians. Amid much controversy, CO2caps (最高限制) and carbon-trading could soon be used to help curb aircraft emissions.
Frequent flyers, free riders
Airlines are accused of having a free ride in terms of air pollution because they pay no tax on the fuel they use for international flights. Even though today's aircraft are about 70% more efficient than those of 40 years ago, concerns over emissions have grown. Despite booming demand for air travel, many airlines are losing money. Now green campaigners want people to think twice before they fly. The opposing voice is particularly loud in Europe, where low-cost carriers are expanding fast on busy shorthaul (短距离) routes. The European Parliament will vote in July on a proposal to limit aircraft emissions.
America is deeply unhappy at the prospect of its airlines being affected. Sharon Pinkerton, a senior representative of the Federal Aviation Administration insisted, on a visit to Brussels last year, that American carriers should be exempted from the scheme. This sets the scene for another transatlantic aviation dispute, to add to the two bitter and long-running disputes over subsidies to Europe's Airbus and the liberalisation of air traffic between the two continents.
The airlines are growing nervous. The big international carriers represented by the International Air Transport Association (IATA) would rather Europe waited for the deliberations of a United Nations body, the International Civil Aviation Organisation (ICAO), which has set technical, legal and safety rules for more than 50 years. International aviation was excluded from the Kyoto protocol on global warming, but only on condition that, by the end of 2007, countries and airlines worked under the umbrella of ICAO to come up with a way of reducing emissions through a trading scheme.
Soon after the end of the second world war the member governments of ICAO agreed that airlines should be free of fuel taxes. Some say this was to outlaw unilateral taxes that could distort markets, but others reckon it was done to boost the fledgling airline in
