Smartphones store a lot of personal data. These devices know our names,the names of our friends，our addresses and where we are right now.1. A weather app needs to know where a person is to report the local forecast，for example.

Many smartphone apps don't cost anything to download and use.But don't be fooled. There's still a price. 2. Those same apps may often send data on to advertisers as well.Those advertisers will pay well to know how people behave and live.Once your data leave a device，you can't get them back. And that data theft may not be harmless. Moreover，those data may tell when someone leaves home and when he gets back. 3. Social media sites often have access to a user's images and posts.

Recently a new online tool has been developed to track the misuse of private data.4. It tells people when their apps are sending data，which can help spot the misuse. SPEProxy identifies the misuse of data using an approach that has already been used to diagnose illnesses.

In the clinical field，a kind of medical software is used to collect data from a patient. Then it compares them to those symptoms of many possible illnesses to make a diagnosis.

Right now，people can only track data with the new tool by going to a website.5. It's also a bit awkward to use.People may not want to go to the trouble of getting online to track their data. A more convenient version that people could install on their phones is in urgent need.

A．It is called SPEProxy.

B．That means it's limited.

C. It is more than convenient to use in computers.

D．Your privacy is what's paying for it.

E．Some apps use those data to do their job.

F．Some apps may charge you much money to operate.

G．They can show how and where people spend their days.

Being able to take advantage of truly unlimited data is a smartphone user's dream, but everyone I've talked to about 5G is more excited about the usage unlocked by next - generation wireless devices. From smart home security to self - driving cars, all the Internet - connected equipment in your life will be able to talk to each other at lightning - fast speed with reduced delay.

"5 G is one of those forerunners, along with artificial intelligence, of this coming data age, ” said Steve Koenig, senior director of market research for the Consumer Technology Association. "Self - driving vehicles are emblematic in this data age - they show application of data completely. With one single task, driving, you have large amounts of data coming from the vehicle itself, and a variety of sensors (传感器)are collecting a lot of information to model its environment as it moves. It's pulling in data from other vehicles about conditions down the road. There's lots of data behind that task, which is why we need the speed and lower latency ((延迟).

AR glasses and virtual (虚拟的)reality headphones haven't yet been inside the mainstream, but tech companies are joyfully saying that such equipment will eventually replace our smartphones. With 5G, that could actually happen. This is notable because companies such as Apple are reportedly developing AR glasses to improve - or even replace - smartphones.

Ericsson showed at February's Mobile World Congress in 2019 how smart glasses could become faster and lighter with a 5G connection, because instead of being weighed down with components, the glasses could rely on outside equipment for processing power.

But don't get too excited. There's still a lot of work to be done in the meantime, including some necessary testing to make sure the radio plays nicely with basic systems and service construction so that 5G isn, t concentrated only in big cities.

1.What does the first paragraph focus on?

A.Potential of 5G. B.The super speed of 5G.

C.Usage of smart equipment. D.The future of smart equipment.

2.Which word can replace　 "emblematic"　 underlined in paragraph 2?

A.available B.productive C.representative D.popular

3.What is tech companies"　 attitude towards the replacement of smartphones?

A.Uncertain. B.Optimistic. C.Cautious. D.Disapproving.

4.Why does much work still need to be done according to the last paragraph?

A.To make radio play nicely. B.To construct big 5G cities.

C.To do 5G trials effectively. D.To expand 5G coverage fully.

Google’s data centres and the offices for its 60,000 staff will be powered entirely by renewable energy from next year,in what the company has called a “landmark moment”.The internet giant is already the world’s biggest corporate buyer of renewable electricity,last year buying 44% of its power from wind and solar farms.Now it will be 100%,and an executive said it would no longer refuse to invest in nuclear power in the future.

Oman said it had taken Google five years to reach the 100% target,set in 2012,because of the complexity involved with negotiating power purchase agreements.The company’s biggest demand for energy is its data centres and it admits their overall thirst for power is growing.

Google was now looking to sign 10-year agreements for low-carbon power that was constant,such as hydro,biomass and nuclear.“We want to do contracts on renewable power,it could be biomass if the fuel source is steady and enough,it could be nuclear.We’re looking at all forms of low-carbon generation.”

But he said new nuclear power was “controversial”,the possible safety consequences were much more “dramatic” than with renewable sources,and the price was “much more difficult to guarantee” than when funding solar panels and wind turbines.“We don’t want to refuse to sign a nuclear agreement if it meets our goals of low price,safety,and other factors.We don’t want to rule that out,but today we can’t positively say there are nuclear projects out there that meet this standard,”he said.

The company’s 100% renewable energy does not mean Google is getting all its energy directly from wind and solar power,but that on an annual basis the amount it purchases from renewable sources matches the electricity its operations consume.

1.A “landmark moment” for Google refers to 　　.

A. its efforts in saving energy

B. its growing demand for employees

C. its progress in using renewable energy

D. its becoming the world’s biggest company

2.What made Google slow in achieving its target?

A. Negotiations of agreements.　　 B. High consumption of energy.

C. Shortage of energy.　　 D. Tight budgets.

3.What can be inferred from Paragraph 4?

A. Nuclear power is an ideal choice.

B. Solar and wind power is not safe enough.

C. It’s unwise to invest solar and wind power.

D. Google is unlikely to use nuclear energy soon.

4.What is the purpose in writing this text?

A. To show Google’s profit goal in global market.

B. To talk about Google’s new move to use energy.

C. To recommend a new kind of renewable energy.

D. To urge the public to use renewable energy.
