On August 29th，Elon Musk, the boss of Tesla, an electric-car maker, announced that some of his customers would find that their cars had suddenly developed the ability to drive farther on a single battery charge. Like many modern vehicles, Mr.Musk's products are best thought of as Internet-connected computers on wheels. The cheaper models in Tesla' line-up have parts of their batteries disabled by the car’s software in order to limit their range. At the tap of a keyboard in Palo Alto, the firm was able to remove those restrictions and give drivers temporary access to the full power of their batteries.
Mr. Musk's computerized cars are just one example of a much broader trend. As computers and connectivity become cheaper, it makes sense to bake them into more and more things that are not, in themselves, computers creating an “Internet of things”, or IoT. It is a slow revolution that has been gathering pace for years, as computers have found their way into cars, telephones and televisions. But the transformation is about to speed up. One forecast is that by 2035 the world will have a trillion connected computers, built into everything from food packaging to bridges and clothes.
Such a world will bring many benefits.Consumers will get convenience. Amazon's Ring smart doorbells, for instance, come equipped with motion sensors(运动传感器) and video cameras. Working together, they can also form what is, in effect, a private CCTV(closed circuit television) network, allowing the firm to offer its customers a“digital neighborhood-watch”scheme and pass any interesting video along to the police.
Business will get efficiency, as information about the physical world that used to be temporary and uncertain becomes concrete and analyzable. Connected cows can have their eating habits and vital signs tracked in real time, which means they produce more milk and require less medicine when they fall ill. Such gains are individually small but, mixed again and again across an economy, they are the raw material of growth potentially a great deal of it.
In the long term, though, the most noticeable effects of the IoT will be on how the world works. One way to think of it is to regard it as the second phase of the Internet. Ever, more companies will become tech companies; the Internet will become widespread. As a result, a series of unsolved arguments about ownership, data, competition and security will spill over from the virtual world into the real one.

By now it's almost common knowledge that spending time in nature is good for you. Areas with more trees tend to be less polluted, so spending time there allows you to breathe easier. Spending time outdoors has been linked with reduced blood pressure and stress and seems to motivate people to exercise more.
“So it'll come as surprise that there's research showing that spending time in nature is good. There are dozens of papers showing that,” University of Exeter Medical School researcher Mathew P.White said.“We get this idea-patients are coning to us and they are asking, ‘Doctor, how long should I spend? ’And the doctor is saying,‘I don't really know.’”
So White and his team decided to find out by using data collected from nearly 20,000 people in England through the Monitor of Engagement with the Natural Environment Survey. And their answer? Two hours a week. People who spent at least that much time in nature either all at once or totaled over several shorter visits were more likely to report good heath and psychological well-being than those with no nature exposure.
Remarkably, the two-hour standard applied to men and women, to older and younger folks, to people from different ethnic backgrounds, occupational groups, socioeconomic levels, and so on. Even people with long-term illnesses or disabilities benefited from time spent in nature- as long as it was at least 120 minutes per week.
While the findings are based on a vast number of people, White cautions that it's rally just a correlation. Nobody knows why of how nature has this benefit, or even if the findings will stand up to more strict investigation.
“I want to be rally clear about this. This is in very early stages.We're not saying everybody has to do 120. This is really to start the conversation, saying, what would a threshold look like? What research do we need to take this to the next step before doctors can have the true confidence to work with their patients? But it's certainly a starting point.”

B.The reason why nature is beneficial is clear.
C.Further study is needed to confirm White's result.
D.The findings of White's survey have bee widely used.

A study has warned that seafood supplies from the world's oceans could be almost gone by the middle of the century. The researchers say there has already been a breakdown in wild populations of almost one third of currently fished sea-foods. The study says that means their catch has fallen by ninety percent from their highest level. Boris Worm of Dalhousie University in Nova Scotia Canada led the intentional team that did the study. Professor Worm says species have recently been disappearing from oceans at an increasing speed. At this rate he says all seafood species could collapse by 2048.
Other studies have also warned about the dangers of overfishing and the effects on ocean environments. But not everyone thinks the oceans are likely to be empty, in, fifty years.Some scientists said parts of the world do have problems but others arc doing a good job of protecting fish populations. Government officials in several countries with large fishing industries also questioned the research.
The study appeared earlier this month in Science magazine.
The researchers say damage to oceans affects not only fish populations but also the productivity of ecosystems. These complex systems help control water quality. The scientists say the loss of different kinds of sea life appears to increase the risk of fish kills and beach closures from harmful algae growth.
The scientists examined the results of thirty-two experiments and observed forty-eight protected areas. They also looked at records of catches worldwide. They studied records from the United Nations Food and Agriculture Organization from 1950 to 2003. And they examined archaeological information and other historical records for twelve coastal areas. That research reached back over a thousand years.
Boris Worm says the findings are, in his words, “beyond anything we suspected.”But he also said the situation is not too late to core. He said that with good fisheries management, some species could completely recover in three to ten years.
