An abandoned girl named Sophie happens to see the big friendly giant (巨人) (BFG for short), who is running through the streets of London and “blowing dreams” to children late at night. The BFG is scared that the girl will give away his secret, so he takes Sophie back to his native Giant Country. In fact, the BFG is a kind-hearted vegetarian, but other giants in his native country like nothing more than eating humans. Sophie and the BFG try to stop these giants from continuing to eat humans. During this period, they become good friends.

    Spielberg's The BFG tells the tale of an unlikely friendship brought to life in an imaginary world. However, many people say the story is a bit too kid-friendly. Optimism is Spielberg's typical tone, but the final victorious battle against the bad guys seems a little bit too easy. And when the BFG fights for the first time against the giants who have been hurting him, it seems confusing how he successfully drives away bad guys who are almost twice his size.

    Spielberg does leave a little for adult viewers to digest. The BFG doesn't want to be seen as a monster by humans，but in the end his own kind ends up caught and locked up in isolation. Will he also be destined (注定) to spend the rest of his days in a remote place alone?

    Despite being made for a younger audience, the film is still worth a watch. It doesn't have gun-fights, death, explosions and the stuff that people seem to be interested in nowadays. But the film takes us back to a more innocent time.

    Motherhood may make women smarter and may help prevent dementia (痴呆) in old age by bathing the brain in protective hormones (荷尔蒙) , U.S. researchers reported on Thursday.

    Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no offsprings, and their brains show changes that suggest they may be protected against diseases such as Alzheimer's (早老痴呆症). University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.

“Our research shows that the hormones of pregnancy are protecting the brain, including estrogen(雌激素), which we know has many neuroprotective (保护神经的) effects,” Kinsley said.

    “It's rat data but humans are mammals just like these animals are mammals,” he added in a telephone interview. “They go through pregnancy and hormonal changes.”

    Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer's and other forms of age-related brain decline.

    “When people think about pregnancy, they think about what happens to babies and the mother from the neck down,” said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida.

    “They do not realize that hormones are washing on the brain. If you look at female animals who have never gone through pregnancy, they act differently toward young. But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations to the brain.”

    A food chain is a simple way of explaining how each living thing gets its food. For example, a simple African food chain might consist of three parts: first, trees and bushes; second, giraffes; and third, lions. Each link in a food chain is food for the next link. Food chains always start with plants and end with animals.

    Plants are at the bottom of the food chain. Scientists call them producers, because they use light energy from the sun to produce food from carbon dioxide and water through photosynthesis（光合作用）. Animals, unlike plants, can't produce their own food. Instead, they must eat plants or other animals. This is why scientists call them consumers.

    Consumer animals fall into three categories. Herbivores（食草动物）eat only plants. Carnivores（食肉动物） eat only other animals. Omnivores eat both plants and animals. In addition to producers and consumers, there are also decomposers(分解者).These organisms, such as bacteria and fungi, feed on decaying(腐烂) matter. They help the food chain by speeding up the decaying process that releases minerals back into the soil to be absorbed by plants as nutrients.

    Most food chains have only four or five links in them. As you go up a food chain, the amount of energy at each level diminishes, because some of the energy is lost in the form of waste or is used up by the organism at the level. That is why it takes many plants, for example, to feed a few giraffes who in turn feed one lion.

    Most animals are part of many different food chains, because they must eat more than one type of food to satisfy their energy needs. All of these interconnected food chains form a more complex structure called a food web. Humans, for example, are at the center of a very complex food web, because we tend to eat many different types of plants and animals.

    Until the 1990s coffee was rarely served in China except at luxury hotels aimed at foreigners. When Starbucks opened its first outlet there in 1999, it was far from clear that the country's avid tea-drinkers would take to such a different-and usually more costly- source of caffeine. Starbucks tried to attract customers unused to coffee's bitter taste by promoting milk and sugar-heavy concoctions(调和) such as Frappuccinos.

    But coffee has become fashionable among the middle class in China. Starbucks now has about 3, 800 outlets in China- more than in any other country outside America. Statista, a business-intelligence portal(门户网站), says the roast coffee market in China is growing by more than 10 % a year. Starbucks and its rivals see big opportunities for expanding there.

    So too, however, do home-grown competitors. A major new presence is Luckin Coffee, Beijing- based chain. Since its founding less than two years ago, it has opened more than 2,300 outlets. On May 17th Luckin's initial public offering on the Nasdaq stockmarket raised more than $570m, giving it a value of about $4bn.

    Luckin's remarkable growth is sign of change. No longer do Chinese consumers see coffee as such a luxury. Most of Luckin's outlets are merely kiosks where busy white-collar workers pick up their drinks, having ordered them online. Super-fast delivery can also be arranged through the company's app. Independent coffee shops are springing up. The growth is striking given the country's reputation for its tea-drinking culture where many residents like to relax in teahouses sipping tea served gracefully.

    But the two markets are different. The teahouses tend to cater to older people who like to spend long hours playing mahjong and gossiping. At the coffee shops it is rare to see anyone over 40. Young people use them for socialising, but much of their interaction is online -sharing photos of their drinks and of the coffee-making equipment. An option on the Chinese rating app Dianping allows users to search for wanghong ("internet viral") coffee houses: ones with particularly photogenic decor(照片装饰) where better to sip and We Chat?
