Eleven months ago, an act of good sportsmanship（体育精神）changed a girls’ running race into something bigger. 
Jenna Huff received a national sportsmanship award from the US Olympic Committee for what she did for Deb Guthmann.
In the race, Jenna was behind Deb until the final few meters of the 5-kilometer race.
Then something awful happened. Deb’s right hip（髋部）broke. She screamed in pain and stopped.
Jenna had never met Deb and had been taught to pass every runner she could to win.
Instead, Jenna stopped with no hesitation.
“Come on.” Jenna told Deb. “We’re going to run.”
Jenna took Deb’s left elbow with her right hand. She helped her jog the last few meters. At the finishing line, she pushed Deb in front of her, reasoning Deb would have beaten her anyway if not for the injury. That act helped Deb’s team win the regional race and advance to the state meet.
Both girls are now 17.
Jenna is still an athlete for her school.
She and her parents went to Colorado to accept an award for the national sportsmanship award. Jenna had to give a five-minute speech to the crowd, a crowd which included a number of former Olympians. “I’m pretty scared about my speech,” Jenna said the other night when we talked on the phone. “You want to hear part of it?” She read me one part including the words from Albert Einstein: “Each of us comes for a short visit, not knowing why, yet sometimes seeming to a divine（神圣的）purpose. From the standpoint of daily life, however, there is one thing we do know：That we are here for the sake of（为了）others.”
Deb is also still running. She received a full scholarship to Emmanuel College in Franklin Springs, Georgia. The award was because of her excellent academic record and great sports potential.
But she recently got hurt again and was unable to run for weeks.
Even so, I am confident Deb will write a happier ending for herself one day. Both of these young women make you feel confident about the future. They are strong, compassionate（富于同情心的）and smart.

Old Problem, New Approaches
While clean energy is increasingly used in our daily life, global warning will continue for some decades after CO 2emissions（排放）peak. So even if emission were to begin decrease today, we would still face the challenge of adapting to climate. Here I will stress some smarter and more creative examples of climate adaptation.
When it comes to adaptation，it is important to understand that climate change is a process. We are therefore not talking about adapting to a new standard, but to a constantly shifting set of conditions. This is why in part at least, the US National Climate Assessment says that: " there is no 'one-size fit all' adaptation." Nevertheless, there are some actions that offer much and carry little risk or cost.
Around the world people are adapting in surprising ways, especially in some poor countries, Floods have some more damaging in Bangladesh in recent decades. Mohammed Rezwan saw opportunity where others saw only disaster. His not-for-profit organization runs 100 river boats that server as floating libraries, schools, and health clinics, and are equipment with solar panels and other communication facilities. Rezwan is creating floating connecticity（连体） to replace flooded roads and highways. But he is also working at a far more fundamental level: his staff people how to make floating gardens fish ponds prevent starvation during the wet season.
Around the world, people are adapting in surprising ways, especially in some poor countries, Fllods have become more damaging in Bangladesh in recent decades. Mobammed Rezwan saw opportunity where others saw only disaster. His not-for-profit organization runs 100 river boats that serve as floating libraries, schoods, and health clinics, and are equipped with solar panels and other communicating facilities. Rezwan is creating floating conmetivity（连接） to replace flooded roads and highways. But he is also working at a far more fundamental level: his staff show people how to make floating gardens and fish ponds to prevent starvation during the wet season.
Elsewhere in Asia even more astonishing actions are being taken. Chewang. Nophel lives in a mountainous region in India, where he is known as the Ice Man. The loss of glaciers(冰川) there due to global warming represents an enormous threat to agriculture. Without the glaciers, water will arrive in the rivers at times when it can damage crops. Norphel's inspiration come from seeing the waste of water over winter, when it was not needed. He directed the wasted water into shallow basins where it froze, and was stored until the spring. His fields of ice supply perfectly timed irrigation(灌溉) water. Having created nine such ice reserves. Nophel calculates that he has stored about 200, 000m 3 of water. Climate change is a continuing process, so Norhel's ice reserves will not last forever. Warming will overtake them. But he is providing a few years during which the farmers will, perhaps, be able to find other means of adapting.
Increasing Earth's reflectiveness can cool the planet. In southern Spain the sudden increase of greenhouses (which reflect light back to space) has changed the warming trend locally, and actually cooled the region. While Spain as a whole is heating up quickly, temperatures near the greenhouses have decreased. This example should act as an inspiration for all cities. By painting buildings white, cities may slow down the warming process.
In Peni, local farmers around a mountain with a glacier that has already fallen victim to climate change have begun painting the entire mountain peak white in the hope that the added reflectiveness will restore the life-giving ice. The outcome is still far from clear, But the World Bank has included the project on its of '100 ideas to save the planet".
More ordinary forms of adaptation are happening everywhere. A friend of mine owns an area of land in western Victoria. Over five generations the land has been too wet for cropping. But during the past decade declining rainfall has allows him to plant highly profitable crops. Farmers in many countries are also adapting like this-either by growing new produce, or by growing the same things differently. This is common sense, But some suggestions for adapting are not. When the polluting industries argue that we've lost the battle to control carbon pollution and have no choice but to adapt, it's a nonsense designed to make the case for business as usual.
Human beings will continue to adapt to the changing climate in both ordinary and astonishing ways. But the most sensible form of adaptation is surely to adapt our energy systems to emit less carbon pollution. After all, if we adapt in the way, we may avoid the need to change in so many others.

A new commodity brings about a highly profitable,fast-growing industry, urging antitrust（反垄断）regulators to step in to check those who control its flow. A century ago ,the resource in question was oil. Now similar concerns ares being raised by the giants（巨头）that deal in data, the oil of the digital age. The most valuable firms are Google, Amazon, Facebook and Microsoft. All look unstoppable.
Such situations have led to calls for the tech giants to be broken up. But size alone is not a crime. The giants' success has benefited consumers. Few want to live without search engines or a quick delivery, Far from charging consumers high prices, many of these services are free (users pay, in effect, by handing over yet more data). And the appearance of new-born giants suggests that newcomers can make waves, too.
But there is cause for concern. The internet has made data abundant, all-present and far more valuable, changing the nature of data and competition. Google initially used the data collected from users to target advertising better. But recently it has discovered that data can be turned into new services: translation and visual recognition, to be sold to other companies. Internet companies' control of data gives them enormous power. So they have a "God's eye view" of activities in their own markets and beyond.
This nature of data makes the antitrust measures of the past less useful. Breaking up firms like Google into five small ones would not stop remaking themselves: in time, one of them would become great again. A rethink is required-and as a new approach starts to become apparent, two ideas stand out.
The first is that antitrust authorities need to move form the industrial age into the 21st century. When considering a merger(兼并), for example, they have traditionally used size to determine when to step in. They now need to take into account the extent of firms' data assets(资产) when assessing the impact of deals. The purchase price could also be a signal that an established company is buying a new-born threat. When this takes place, especially when a new-born company has no revenue to speak of, the regulators should raise red flags.
The second principle is to loosen the control that providers of on-line services have over data and give more to those who supply them.Companies could be forced to consumers what information they hold and how much money they make from it. Governments could order the sharing of certain kinds of data, with users' consent.
Restarting antitrust for the information age will not be easy But if governments don't wants a data economy by a few giants, they must act soon.
61.Why is there a call to break up giants?
| A． |
They have controlled the data market |
| B． |
They collect enormous private data |
| C． |
They no longer provide free services |
| D． |
They dismissed some new-born giants |
62.What does the technological innovation in Paragraph 3 indicate?
| A． |
Data giants' technology is very expensive |
| B． |
Google's idea is popular among data firms |
| C． |
Data can strengthen giants' controlling position |
| D． |
Data can be turned into new services or products |
63.By paying attention to firms' data assets, antitrust regulators could .
| A． |
kill a new threat |
| B． |
avoid the size trap |
| C． |
favour bigger firms |
| D． |
charge higher prices |
64.What is the purpose of loosening the giants' control of data?
| A． |
Big companies could relieve data security pressure. |
| B． |
Governments could relieve their financial pressure. |
| C． |
Consumers could better protect their privacy. |
| D． |
Small companies could get more opportunities. |
Before birth, babies can tell the difference between loud sounds and voices. They can even distinguish their mother's voice from that of a female stranger. But when it comes to embryonic learning（胎教）, birds could rule the roost. As recently reported in The Auk: Ornithological Adrances, some mother birds may teach their young to sing even before they hatch(孵化). New-born chicks can then imitate their mom's call within a few days of entering the world.
This educational method was first z observed in 2012 by Sonia Kieindorfer,a biologist at Flinders University in South Australia,and her colleagues. Femake Australian superb fairy wrens were found to repeat one sound over and over again while hatching their errs, when the errs were hatched, the baby birds made the similar chirp to their mothers-around that served as their regular "feed me!" call.
To find out if the special quality was more widespread in birds, the researchers sought the red-backed fairy wren, another species of Australian songbird. First they collected sound data from 67 nests in four sites in Queensland before and after hatching. Then they identified begging calls by analyzing the order and number of notes. A computer analysis blindly compared calls produced by mothers and chicks, ranking them by similarity.
It turns out that baby red-backed fairy wrens also emerge chirping like their moms. And the more frequently mothers had called to their errs, the more similar were the babies' begging calls. In addition, the team set up a separate experiment that suggested that the baby birds that most closely imitated their mom's voice were rewarded with the most food.
This observation hints that effective embryonic learning could signal neurological(神经系统的) strengths of children to parents. An evolutionary inference can then be drawn." As a parent, do you invest in quality children, or do you invest in children that are in need?" Kleindorfer asks." Our results suggest that they might be going for quality."

Hollywood's theory that machines with evil(邪恶) minds will drive armies of killer robots is just silly. The real problem relates to the possibility that artificial intelligence(AI) may become extremely good at achieving something other than what we really want. In 1960 a well-known mathematician Norbert Wiener, who founded the field of cybernetics（控制论）, put it this way "If we use, to achieve our purposes, a mechanical agency with whose operation we cannot effectively interfere(干预), we had better be quite sure that the purpose which we really desire."
A machine with a specific purpose has another quality, one that we usually associate with living things a wish to preserve its own existence. For the machine, this quality is not in-born, nor is it something introduced by humans; it is a logical consequence of the simple fact that the machine cannot achieve its original purpose if it is dead. So if we send out a robot with the single instruction of fetching coffee, it will have a strong desire to secure success by disabling its own off switch or even killing anyone who might interfere with its task. If we are not careful, then, we could face a kind of global chess match against very determined, super intelligent machines whose objectives conflict with our own, with the real world as the chessboard.
The possibility of entering into and losing such a match should concentrating the minds of computer scientists. Some researchers argue that we can seal the machines inside a kind of firewall, using them to answer difficult questions but never allowing them to affect the real world. Unfortunately, that plan seems unlikely to work we have yet to invent a firewall that is secure against ordinary humans, let alone super intelligent machines.
Solving the safety problem well enough to move forward in AI seems to be possible but not easy. There are probably decades in which to plan for the arrival of super intelligent machines. But the problem should not be dismissed out of hand, as it has been by some AI researchers. Some argue that humans and machines can coexist as long as they work in teams-yet that is not possible unless machines share the goals of humans. Others say we can just "switch them off" as if super intelligent machines are too stupid to think of that possibility. Still others think that super intelligent AI will never happen. On September 11, 1933, famous physicist Ernest Rutherford stated, with confidence, "Anyone who expects a source of power in the transformation of these atoms is talking moonshine." However, on September 12, 1933, physicist Leo Szilard invented the neutron-induced(中子诱导) nuclear chain reaction.
