China’s war on garbage is as digital as the country itself. Think QR codes attached to trash bags that allow the government to trace exactly where its trash comes from.
On July 1, Shanghai began a compulsory garbage sorting program. Households and companies must classify their wastes into four categories and dump them in appointed places at certain times. The strict program became a headache for some residents. Not even the most environmentally conscious person can get all the answers right. Like, which bin does the newspaper you just used to pick up dog poop (粪便)belong to?
Gratefully, China’s tech startups are here to help. For instance, China’s biggest internet companies responded with new search features that help people identify what wastes are “wet”, “dry”, “toxic”, or “recyclable”. Simply pull up a mini app on WeChat, Baidu or Alipay and enter the keyword. The tech firms will give you the answer and why.
Alipay, Alibaba’s electronics payment company, claims its garbage sorting mini app added one million users under just three days. The mini app has so far indexed (编索引) more than 4,000 types of rubbish. Its database is still growing, and soon it will save people from typing by using image recognition to classify trash when they snap a photo of it. If people are too busy or lazy to hit the collection schedule, well, startups are offering trash service at the doorstep. A third-party developer helped Alipay build a recycling mini app and is now collecting garbage from 8,000 apartment complexes across 11 cities. To date, two million people have sold recyclable materials through its platform.
Besides helping households out, companies are also building software to make property managers, life easier. Some residential complexes in Shanghai began using QR codes to trace the origin of garbage. This way, regulators in the region know exactly which family has produced the trash and fine violators.
1.What are some residents confused about?
A.Environmental knowledge. B.Bin for dog poop.
C.Some waste classification. D.Time for dumping.
2.What is the advantage of trash service at the doorstep?
A.It provides time flexibility. B.It reduces household waste.
C.It saves people from typing. D.It classifies rubbish properly.
3.Who will probably most welcome the use of QR codes?
A.Third-party developers. B.Company managers.
C.Community administrators. D.Rubbish collectors.
4.What is the main idea of this article?
A.People need recycling apps badly.
B.People should classify their rubbish.
C.How regulators benefit from the tech.
D.How China uses tech to sort waste.

The "cloud war" is taking place as the dispute between the United States and China about data hacking and computer network security grows stronger. Chinese companies such as Alibaba, Baidu and Huawei are expanding within their country and gaining customers in other countries. They are creating data centers in multiple countries and trying to sell data management services throughout the world.
The increasing competition in cloud computing and storage incurs the new challenge and worries some experts. They are concerned about the safety of data. After all, companies often use the cloud to store important, confidential information and to operate such activities as data-driven machinery, telecommunications, banking and transport systems — including plans for driverless vehicles.
Lee Branstetter is an associate professor of economics at the Heinz School of Policy and Management of the Carnegie Mellon University. He told many multi-national companies "have serious concerns about the protection of their intellectual property （知识产权）."Branstetter said some of these large companies already believe they have lost valuable information.
Sheila Jasanoff is the director of the program on science, technology and society at Harvard's Kennedy School. She called the cloud computing industry "unruly". In other words, the industry is not strictly governed.
"People （in the business） are making rules as they go along or taking advantage of the lack of rules," Jasanoff said. She said cloud computing companies are not clear about what security measures they are promising customers. She is worried that a major accident may happen before governments realize the need for stronger rules in the cloud computing industry. She believes there should be internationally-accepted rules to meet the new challenge. But she does not believe an international agreement will be reached anytime soon.
1.What does the "cloud war" refer to?
A.The war up in the sky.
B.Some kind of cold war.
C.The China-US relationship.
D.The competition on the "cloud".
2.What concerns some experts according to Paragraph 2?
A.Information security.
B.Wars among countries.
C.The storage of “cloud”.
D.The lack of technology.
3.Which of the following may be consistent with Jasanoff's opinion?
A.A major accident is bound to take place soon.
B.An agreement is to be reached in the near future.
C.The cloud industry needs guiding and monitoring.
D.Governments have kept an eye on cloud industry.
4.What is the best title for the text?
A.China's Rise or Not
B.New War, New Challenge
C.Chances on Cloud Information
D.Growth of Cloud Computing Industry

Security—for the information on your smartphone, as well as for the phone itself is a hot topic these days．The truth is that you’re packing a lot of sensitive information on your phone, and you should keep it safe．
When it comes to physical security, iPhone users would do well to download Find My iPhone, a free app from Apple that allows you to visit a website and see your (lost, stolen or misplaced) phone on the map．You can then sound an alarm, send a message that will pop up on its screen, lock the phone or erase all your data．
Android does not have an exact equivalent(等价物), but there are plenty of alternatives．A free app called Lookout offers the find my phone feature．The paid version allows you to wipe the data from your phone remotely．
Then there is your coffee shop’s WiFi network．Anyone with minimal technical expert skill can snoop on(窥视) people using shared wireless networks, harvesting passwords and other personal data．Lookout’s apps will caution you when you’ve logged on to an insecure network, but cannot protect you once you’re there．
In order to protect yourself on such networks, you can use a virtual private network, or V．P．N．This turns all your activity into nonsense to anyone trying to read along with you from across the Starbucks．It also keeps websites from tracking you and, if you’re traveling, allows you to get access to sites that may be blocked in other countries．
If you have an iPhone, the simplest V．P．N．app is probably Hotspot Shield, whose distinguishing feature is said to be that it automatically kicks in each time you start browsing (浏览), as opposed to other V．P．N．apps that require you to start them up manually(手动)．This matters, because even if you decide you want a V．P．N．app, you want to spend approximately zero time thinking about it．For the most part, that was true of Hotspot Shield, though occasionally it took a while to connect or temporarily lost connection without warning．I found myself having to turn the app on and off sometimes, which involved setting my phone constantly．
If even reading about the setting on your phone drives you crazy, then it is probably best to stay away from a V．P．N．app．But if you’re the type who can’t resist checking your bank balance from your comer bar, the hassle (麻烦) may be preferable to the risk．

China is a country on the move- especially around its Lunar New Year holiday. This year, the holiday crush（客流量） promises to be even heavier than before。
Government officials estimate that Chinese people will take to the air, roads and railways 3.62 billion times over a 40-day period around the nation's most important holiday this year as people push their way home for family gatherings or to satisfy their new-found passion for travel.
Getting tickets to all those would-be travelers is a discounting challenge that annually tries patience. And it is the railway system that routinely is most unable to cope. Railways are the transport of choice for low-cost long-distance travel, and that's where the ticketing system routinely falls down
Much of the criticism has, focused on the railway's-online purchasing system. Which has been unable to keep pace with the huge demand and also failed to stop scalpers（票贩子） from ending up with many of the hard-to-find tickets.
While insisting that online sales were the fairest way to get tickets for travelers, railway officials told
reporters that the public need to be patient. Efforts were being made to provide online identity checks that would reduce the ticket scalping problems. While officials had little good news for rail passengers, they did manage to bring a few smiles to those traveling by car as the country's extremely expensive highway tolls （通行费）will be free of charge for the period of the official holiday.
1.Which of the following words can replace the underlined word "discounting" in Paragraph 3?
A. Promising.
B. Discouraging.
C. Pleasing.
D. Rewarding.
2.According to the text, getting tickets_____. around the official holiday.
A. is just a piece of cake
B. is more costly
C. takes great effort
D. is convenient for travelers
3.We can learn from the text that _______. around the New Year holiday.
A. there will be 3. 62 billion people going home
B the railway system will be facing more stress
C.. people's complaint .focus on the failure of online purchase
D. not railways but cars are the best choices for traveling
4.Which of the following can best describe the author's attitude to the railway service?
A. Objective.
B Doubtful.
C. Satisfied
D．Worried.
