On August 29th, as Hurricane Dorian tracked towards America’s east coast, Elon Musk, the boss of Tesla, an electric-car maker, announced that some of his customers in the storm’s path 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’s 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”.
Such a world will bring many benefits. Consumers will get convenience, and products that can do things non-computerized versions cannot. Businesses will get efficiency, as information about the physical world that used to be uncertain becomes concrete and analyzable.
In the long term, though, the most obvious effects will be in how the world works. Ever more companies will become tech companies; the internet will become everywhere. As a result, a series of unresolved arguments will spill over from the virtual world into the real one.
Start with ownership. As Mr Musk showed, the internet gives firms the ability to stay connected to their products even after they have been sold, transforming them into something closer to services than goods. That has already made the traditional ideas of ownership unclear. When Microsoft closed its ebook store in July, for instance, its customers lost the ability to read titles they had bought (the firm offered refunds). That shifts the balance of power from the customer to the seller.
Virtual business models will jar in the physical world. Tech firms are generally happy to move fast and break things. But you cannot release the beta version (测试版) of a fridge. Apple, a smartphonemaker, provides updates for its phones for only five years or so after their release; users of Android smartphones are lucky to get two. But goods such as washing machines or industrial machinery can have lifespans of a decade or more. Firms will need to work out how to support complicated computerised devices long after their original programmers have moved on.
Data will be another flashpoint. For much of the internet the business model is to offer “free” services that are paid for with valuable user data, collected with consent (同意) that is half-informed at best. In the virtual world, arguments about what should be tracked, and who owns the resulting data, can seem airy and theoretical. In the real one, they will feel more urgent.
Predicting the consequences of any technology is hard — especially one as universal as computing. The emergence of the consumer internet, 25 years ago, was met with starry-eyed optimism. These days the internet’s faults dominate the headlines. But the people have the advantage of having lived through the first internet revolution — which should give them some idea of what to expect.
1.From the passage we can tell that Tesla can ______.
A.drive faster than usual in extreme weather B.adjust the range of its battery power

A.Early adopters of certain apps find that they ceased to work after the firm lost interest.
B.The insurance company uses data from fitness trackers to adjust customers’ premiums(保费).
C.Computerized machinery can’t predict its breakdowns or schedule preventive maintenance.
D.A high-tech fridge company restricts its customers from repairing their fridges themselves.
3.The underlined word jar probably means _______ in this context.
A.boom B.conflict C.vanish D.expand
4.This passage is mainly about _______.
A.how the world will change as computers spread into everyday objects
B.the adoption of electric vehicles and the possible problems to expect

A new study says one part of the human brain may become smaller as the result of a condition known as jet lag(时差). People with jet lag feel extremely tired for several days. They may also have problems in thinking clearly and remembering.
Recently a researcher at the University of Bristol in Britain reported the findings of his jet lag study, which involved twenty women who worked for international airlines. They had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights. The other half spent more than fourteen days in their home areas.
The researcher took some saliva (唾液) from the women’s mouths to measure levels of a hormone that increases during stress. He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains to measure the size of the brain’s temporal lobes (脑叶).
It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction on the visual memory test. And their saliva samples showed higher levels of stress hormones.
The researcher believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory.
Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find out if too much jet lag could permanently affect memory.
1.It can be inferred from the text that ______.
A. the conclusion is refused by many scientists
B. scientists fear that this research is not done properly
C. every scientific conclusion needs the support from many tests
D. the women who were examined in the research were not healthy
2.From the result of the research we can see that _____.
A. the women who have longer rest at home perform better on the test.
B. the women who fly in short time have smaller right temporal lobes
C. the women who have longer flights fail the memory test
D. the women who rest more than 14 days produce more hormones
3.What is the subject discussed in the test?
A. The cause of jet lag.
B. A story of a group of flight attendants.
C. The importance of having enough rest after flights.
D. A research about the effects of jet lag on the brain

A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. Jet lag interferes with a person's normal times for sleeping and waking. People with jet lag may feel extremely tired for several days. They also may have problems thinking clearly and remembering.
Kwangwook Cho is a researcher at the University of Bristol in Britain. He reported the findings of his jet lag study in the publication Nature Neuroscience.
The study involved twenty young women who worked for international airlines. The women had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights. The other half spent more than fourteen days in their home areas.
Mister Cho took some fluid from the women's mouths to measure levels of a hormone that increases during stress. He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains using magnetic resonance imaging. This is a way to measure the size of the brain's temporal lobes(颞叶).
It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones.
