Li Shuangying said her 18yearold son， who just took this year's college entrance exam， would become a professional in the artificial intelligence (AI) field.
Artificial intelligence is the branch of computer science concerned with making computers behave like humans. The requirement for AI talents is a solid foundation of maths and English， so for senior high graduates， they should have a higher mathematical thinking ability and have a good command of English if they want to become professionals in AI.
Li Shuangying said her son always has been one of the top students in his class at one of the leading high schools in Zhongshan， Guangdong province. Zhongshan， which neighbors Guangzhou， has been one of China's pioneering cities in embracing reform and opening up. It flourished(繁荣) on laborintensive industries， but recent rising labor shortages and costs have become a real threat. In response， local manufacturers(制造商) have been quick to embrace automation(自动化)and adopt AIassisted robots for survival.
The company Li works for， a mediumsized home appliance manufacturer with annual output of about 1 billion yuan($150 million)， is no exception. Li said she used to bring her son to her workplace from time to time， and he has developed a strong interest in AI， automation and robots.
“Our family all agree that AI is the trend， and it holds great potential for future development，” Li said. That view is shared by many college students and their parents， who consider AI a desirable major.

Educating girls quite possibly harvests a higher rate of return than any other investment available in the developing world. Women's education may be an unusual economical field， but increasing women's contribution to development is actually as much an economic issue as a social one. And economics， with its focus on encouragement， provides an explanation for why so many girls are rid of an education.
Parents in lowincome countries fail to invest in their daughters because they do not expect them to make an economic contribution to the family： girls grow up only to marry into somebody else's family and bear children. Girls are thus seen as less valuable than boys and are kept at home to do housework while their brothers are sent to school—the prophecy(观念)becomes selffulfilling， trapping women in a vicious(恶性的) circle of neglect.
An educated mother， on the other hand， has greater earning abilities outside the home and faces an entirely different set of choices. She is likely to have fewer but healthier children and can insist on the development of all her children， ensuring that her daughters are given a fair chance. The education of her daughters then makes it much more likely that the next generation of girls， as well as boys， will be educated and healthy. The vicious circle is thus transformed into a virtuous circle.
Few will argue that educating women has great social benefits. But it has enormous economic advantages as well. Most obviously， there is the direct effect of education on the wages of female workers. Wages rise by 10 to 20 percent for each additional year of schooling. Such big returns are impressive by the standard of other available investment， but they are just the beginning. Educating women also has a significant effect on health practices， including family planning.

On the school playground in Los Tomes, José, a lone child, plays a ballandcup game. The eightyearold is the school's only pupil. His teacher, Nilda, herself a former pupil, says that enrolment(注册入学) has dropped from 65 when she started teaching 43 years ago. Drought has driven families away, she says, “Only the old remain.”
Los Tomes is an agricultural cooperative, one of 178 in Chile's Coquimbo region. Nineteen communities try to grow wheat and raise sheep and goats on 2,800 hectares. A decadelong drought has made that harder. Hilltop springs where the animals once drank have dried up. As the number of herds(畜群) decrease, farmers' children moved away to take jobs in cities or at copper mines.
① Hope for Los Tomes comes in the form of three 60squaremetre nets stretched between poles on a ridge(山脊) above the community. These nets capture(捕捉)droplets(水珠) from the fog that rolls in from the sea 4 kilometers away. They flow down to two troughs(槽), from which animals drink. The nets can harvest 650 litres of water a day.
② Chile has been investigating fog capture since the 1950s. The fog can be harvested with the help of a coastal mountain range and strong winds. Earlier attempts to turn the mist into usable water failed. In 1990 fog nets at a fishing village captured 8,000 litres a day. Villagers argued about how to share responsibility for maintaining the nets.
Climate change, which is expected to decrease rainfall in the region, has inspired a new search for sources of water. The project at Los Tomes is part of an attempt to capture fog. “The question is not whether the fog collectors work but who's going to provide and maintain them,” says Daniela.
At a community north of Los Tomes, three 150squaremetre fog catchers feed a plantation of young olive trees. When the trees mature, they will produce 750 litres of organic olive oil a year. The water source will be a big selling point. A privately owned brewery(啤酒厂)in Pena Blanca was quick to spot fog water's marketing appeal.
③ The development fund paid 5.6 million pesos each piece to put up the structures in Los Tomes；when the nets wear out, the villagers will have to replace them at a cost of 100,000 pesos each. Coquimbo has more than 40,000 hectares of land with the right conditions for putting up fogcatchers. If it were fully employed, the region could harvest 1,400 litres a second, enough to supply all its drinking water.
④ That might attract back educated young people from the cities. A chance to develop tourism near the Fray Jorge national park, a rainforest which has survived thanks to its own natural fogcollection mechanism, brought Salvador to his birthplace. “Roots, the land and the desire to start this brought me back, says Salvador.

HYDROGENPOWERED cars have had a rough ride. Back in 2003, they were sold as “one of the most encouraging, innovative technologies of our times” by US president at the time George W. Bush. Then the Tesla revolution came along and they were left in the dust by their batterydriven electric rivals.
Now, there are signs of a comeback. A recent survey of more than 900 global automotive executives by consulting firm KPMG found that 52 percent rated hydrogen(氢) fuel cell vehicles as a leading industry trend. Japan has announced plans to put 40,000 hydrogen vehicles on the road in the next five years, and South Korea 16,000. Germany wants to have 400 refueling stations for hydrogen vehicles by 2025 and California has already opened 35.
This renewed push has its doubts. Tesla chief Elon Musk, for example, has dismissed hydrogen cars as being “extremely silly”. But Joan Ogden at the University of California, Davis, sees a future in which hydrogen and electric vehicles play complementary(互补的) roles. “There are arguments for having both,” she says.
Like electric cars, hydrogen vehicles produce zero pollutants, so they don't damage our health or the climate. The main difference is that hydrogen cars use a fuel cell instead of a battery to power an electric motor. Hydrogen is stored in a tank and fed into the fuel cell, where its chemical energy is changed into electrical energy.
Hydrogen cars are finally becoming commercially practical because fuel cells have become smaller and lighter, says Matthew Macleod at Toyota, which began selling the Mirai, one of the first massmarket hydrogen cars, in 2014 for $60,000.
We are also figuring out better ways to transport and store hydrogen, says Michael Dolan at Australia's national science organization, the CSIRO. Last month, his team showed that hydrogen gas can be changed into liquid ammonia(氨) for transportation, then changed back. Liquid ammonia takes up less space and is less flammable than hydrogen gas, making it easier to ship to refueling stations.
The ability to rapidly refuel is one of the main advantages hydrogen vehicles have, says Macleod. Filling up a hydrogen car takes about the same time as filling a petrol one, rather than the hours it typically takes to recharge an electric car's battery. You can also go further on a full tank of hydrogen—about 500 kilometers, compared with 300 kilometers for a standard fully charged battery.
But although hydrogen reacts cleanly—the only thing coming out is water—hydrogen vehicles are more energyconsuming than electric ones if you take fuel production and transport into consideration, says Jake Whitehead at the University of Queensland, Australia.
At the moment, most hydrogen is from natural gas—a fossil fuel. “Green” hydrogen can be made by splitting water using solar or wind power, but this involves multiple steps, each using energy along the way. In contrast, a single energy step is required to directly recharge a car battery at home.
1.What can we infer from the first three paragraphs？
A. Gorge W. Bush once drove a hydrogen car on a bumpy road.
B. Joan Ogden thinks hydrogen and electric cars can exist and improve together.
C. Japan will have more hydrogen cars than electric cars on the road in the next 5 years.

3.What can we know about the differences between hydrogen and electric cars？
A. Comparatively, for hydrogen cars, fuel production and transportation is cheaper.
B. On a fully charged battery, electric cars can cover a longer distance.
C. It takes far more time to refuel hydrogen cars than to recharge a battery.
D. Hydrogen cars use a fuel cell rather than a battery to provide power.
4.What's the author's attitude towards hydrogenpowered cars？
A. Opposed. B. Approved. C. Skeptical. D. Objective.
