Tech giants Apple and Google are teaming up to create a system that would let smart phone users know when they've come into contact with someone who has COVID-19.
The technology would rely on the Bluetooth signals that smart phones can both send out and receive 1aperscn tests positive(阳性) for COVID-19, they could inform public health authorities through an app. Those public health apps would then warn anyone whose smart phones bad come tear the infected person's phone in the previous 14 days. The technology could be used on both Google Android phones and Apple iPhones.
The companies insist that they will preserve smart phone users' privacy and their technology will be used only by public health authorities to trace the spread of COVID-19. Smart phone users can choose to use it. The software will not collect data on users' physical locations or their personally identifiable information. People who test positive would remain unknown to the public, both to the people who came in contact with them and to Apple and Google. “Privacy is of greatest importance in this effort,” the companies said in a joint statement.
The American Civil Liberties Union has warmed that using cellphone data to handle the pandemic carries risks of “destruction of privacy”. In a statement on Friday, ACLU cyber security counsel Jennifer Granick said, The system also can't work well if people don’t trust it”. She said that the joint Apple and Google project “appears to reduce the worst privacy risks, but there is still room for improvement.” She added that the contact tracing app should be used only for public health purposes and only for the duration of this pandemic.
Public health officials say the contact tracing -finding people who have been in contact with an infected person will be a key step in lifting shelter in-place restrictions.
It would allow people who are known to have been exposed to the virus to isolate themselves, while letting others recover normal activities.
1.What is the main purpose of the passage?
A.To advertise for public health. B.To introduce a contact tracing system.
C.To warn the public of risks of COVID-19. D.To raise people's awareness of privacy protection.
2.What do the companies promise to do in particular?
A.Warn people who test positive. B.Protect infected people's privacy.
C.Work with public health authorities. D.Collect data on users physical locations.
3.What does the underlined sentence in Paragraph 4 suggest?

In a country known for high-tech ambitions and giant state-owned firms, the plight of street hawkers may seem insignificant. But in China these days, people like Shui Jin, an old lady riding a wooden cart filled with fruit, are in the spotlight.
Faced with rising unemployment, officials have concluded that pavement stands can help solve the economy’s problems. Shui Jin, who used to face the danger of heavy fines, may sell her fruit with more confidence as she slowly makes her way through the narrow lanes of Suzhou. Her family needs the money. Both her daughters-in-law recently lost their jobs, among the tens of millions in China hurt by the coronavirus outbreak.
The government’s support for street hawkers is something of an about-turn. For years Municipal authorities pushed out hawkers, trying to tidy up the colourful chaos that once characterized China’s cities. In the name of “civilizing” urban life, they wanted to see dumplings, plastic toys and T-shirts bought inside shopping malls, not sold from the back of carts. But on June 1st Li Keqiang, the prime minister, signalled a change. Stopping by a snack stand in the city of Yantai, he declared that street hawkers and small shops were vital to the economy. “Only when the people are in good shape can the nation be in good shape,” he said.
Mr. Li’s compliment has produced a feeling of excitement about the revival of China’s “street- stand economy”. At least 27 provinces and cities have announced that they will create markets for hawkers or, in some cases, let them move their things being sold onto the pavement in front of their shops. The shining example is Chengdu, a busy and noisy city in Sichuan province in the south-west, where businesses started setting up street stands in March. The local government there claims that more than 10000 jobs have been created in the process.
1.According to the passage, street hawkers in China used to_________.
A.clean the street B.be in the spotlight
C.run a shop D.be given heavy fines
2.Which of the following can best replace the underlined phrase “an about-turn” in Paragraph 3?
A.a local government B.a complete change
C.a good shape D.a clean city
3.Why did the prime minister say street hawkers and small shops were vital to the economy?
A.They can make few jobs created for the unemployed people.
B.They can make the people and the nation in good shape.
C.They can make people like Shui Jin selling their fruit.
D.They can make the city tidy and noisy.
4.What is the main idea of the text?
A.China turns to once-banned hawkers to revive its economy.
B.China’s street-stand economy has a long history.
C.China has high-tech ambitions and giant state-owned firms.
D.China is now faced with rising unemployment.

The popularity of Chinese-owned video-sharing service TikTok (抖音) continues to grow among young people in the United States. In 2019, experts say the service more than doubled its American user base to 37 million. TikTok is especially popular with teens and young adults.
The service lets users create and share their short videos that they think interesting and useful, and many of them are under 15 seconds. The TikTok app offers a wide choice of sounds, brief parts of songs and special effects tools to help create a video. Some TikTok-based memes are very popular. Videos often include popular songs from well-known artists and TikTok has even helped launch the careers of new music stars.
TikTok is considered a competitor to the video-sharing app Snapchat, as well as Facebook’s Instagram service. Snapchat and Instagram also mainly interest young users with a wide mix of photos and videos centered largely on fashion, pop culture and humor.
Last year, TikTok was the second-most downloaded app from Apple and Google stores. Only WhatsApp was downloaded more. Research company Sensor Tower guesses people have downloaded the TikTok app 1.65 billion times.
TikTok has been used by many major companies to reach young people who use little or no traditional media. One of those companies is American-based e. l. f. Cosmetics. The makeup company’s chief marketer, Kory Marchisotto, said that TikTok is “where the Gen Z party is”. Gen Z is a name used to call the generation born between the late 1990s and the early 2000s. “That’s where they’re all hanging out,” Marchisotto said.
Companies appearing on TikTok can make money through advertising. Often, the companies create user “challenges” as part of their ad campaigns. In challenges, users are invited to publish their own videos in which they perform similar dance moves. One campaign by e. l. f. Cosmetics, for example, asked people to wink and move their lips while following a song. TikTok users created 3 million videos that received more than 4 billion view.
1.Which word can best describe the videos created on TikTok
A.Traditional. B.Formal. C.Various. D.serious.
2.Which was downloaded most from Apple and Google stores last year?

[1] I was interested in different science fiction ideas and technologies. But there is one theme in science fiction that has always troubled me: when technology subverts (颠覆) its creators.
[2] I’ve been involved in dozens of technology projects. I have to admit that seldom in our design or business discussions have we spent much time on the possible negative impact of our work on the world. Instead, in most cases we just create technology because we see a need, or to solve a problem.
[3] Technology has been responsible for an age of distraction. Recently while driving from northern New York City to the Elmira area, I saw signs saying, “Next texting stop is three miles ahead. Don’t text and drive.” Most states have already outlawed texting while driving, and yet we hear almost weekly of traffic accidents caused by drivers tapping on smartphones. I don’t believe Steve Jobs and Apple dreamed that the iPhone, or smartphones in general, would give rise to this level of distraction.
[4] In a recent Harvard Business Review piece entitled “Liberal Arts (人文科学) in the Data Age,” the author writes about the importance of reconnecting humanism with engineering approach. Many of today’s engineers have been so focused on creating new technologies that their short term goals risk covering up unintended long-term outcomes. A few companies, such as Intel, are forward-thinking enough to include ethics (伦理学) professionals on their staff. At this point all tech companies should start getting serious about the need to hire people with backgrounds in areas such as psychology and philosophy (哲学).
[5] My hope is that we can all move a little more in creating technology that is both impactful and thoughtful in its engagement with our lives and the world.
1.What inspires people to create technologies according to the writer?
A.A desire to think and create. B.An interest in technology.
C.A need to settle a problem. D.An idea from science fiction.
2.Why is the example of “texting” mentioned in Paragraph 3?
A.To tell the arrival of a new age. B.To criticize wrong driving behaviors.
C.To stress Steve Jobs’ contributions. D.To show negative impact of technology.
3.Which of the following can best replace “give rise to” in Paragraph 3?
A.Cause. B.Resolve.
C.Confirm. D.Permit.
4.According to the writer, forward-thinking tech companies should ________.
A.value liberal arts professionals B.put huge profits first
C.focus on creating new technologies D.hire bookish engineers
5.What does the writer want to get across to readers?
A.The significance of Liberal Arts. B.Less dependence on technology.
C.The importance of humanism in technology. D.Diverse views on science fiction.

Apple has entered the textbook market. The tech giant（科技巨头） introduced iBooks textbooks a couple of weeks ago when it announced its iBooks 2 platform. They are digital books in many subjects taking in science, maths, history and geography.
Apple developed its iPad-based textbooks in conjunction with（连接）major textbook publishers. The company offers a collection of textbooks for high school students.
Apple says it offers a “new textbook experience” and suggests its iBooks textbooks are “the next chapter in learning”. It sounds like good news for pupils and students. Think of it. No more carrying heavy backpacks full of textbooks. Every textbook you require can be stored on your iPad. No more having to buy expensive textbooks which you will only use for a year or two and then sell or give away.
Of course there’s a catch. You need to own an iPad and as you know, it is not cheap. You also need to buy digital textbooks, mostly priced each at $14.99 (94.74 yuan) or less. Textbook publishing was worth $ 8.7 billion in the US alone last year. And the rest, as they say, is history. Will Apple revolutionize learning? Will digital books take over completely in education? That remains to be seen.
1.What is the best title of the text?
A．Apple Enters New Market B．A Different Way of Learning C．Experience Digital Texbooks D．Say Good-bye to Tradition
2.iBooks textbooks will do good to pupils and students because ________.
A．they are free to get B．they are easy to carry
C．they are ipad-based D．they are favorite gifts
3.The underlined words “a catch” in Paragraph 4 are closest in meaning to “________.”
A．an advantage B．a surprise
C．a problem D．an order
4.What can we know from that last paragraph?
A．iPad-based textbooks have changed our learning.
B．Traditional textbooks will be replaced sooner or later.
C．Apple has earned a lot from the textbook market.
D．Digital books have disadvantages and advantages.

Nice Places in America
The Doaks’ House in Waterford, Ohio
In the small town of Waterford, Ohio, one local household stands out. One fall Saturday every other year or so, Roger and Shirley Doak open their doors for family, friends and strangers. Since the 1960s, they’ve turned a day devoted to making apple butter into an all-day event. They start the fire at dawn, then take turns stirring it, and have a buffet until sunset. By the end of the day, they’ve created apple butter together.
Pflugerville High School, Texas
In a school of about 2,300 people, students love each other, regardless of race or ability.

Last summer, two nineteenth-century cottages were rescued from remote farm fields in Montana, to be moved to an Art Deco building in San Francisco. The houses were made of wood. These cottages once housed early settlers as they worked the dry Montana soil; now they hold Twitter engineers.
The cottages could be an example of the industry’s unusual love for “low technology”, a concept associated with the natural world, and with old-school craftsmanship（手艺）that exists long before the Internet era. Low technology is not virtual (虚拟的) —so, to take advantage of it, Internet companies have had to get creative. The rescued wood cottages, fitted by band in the late eighteen-hundreds, are an obvious example. Other companies are using a broader interpretation（阐释）of low technology that focuses on nature.
Amazon is building three glass spheres filled with trees, so that employees can “work and socialize in a more natural, park-like setting.” At Google’s office, an entire is carpeted in glass. Facebook’s second Menlo Park campus will have a rooftop park with a walking path.
Olle Lundberg, the founder of Lundberg Design, has worked with many tech companies over the years. “Our tech engineers are the ones who feel impoverished, because they’re surrounded by the digital world,” he says. “We’ve found that introducing real crafts is one way to regain their individual identity.”
This craft-based theory is rooted in history. William Morris, the English artist and writer, turned back to pre-industrial arts in the eighteen-sixties, just after Industrial Revolution. The Arts and Crafts movement defined itself against machines. “Without creative human occupation, people became disconnected from life.” Morris said.
Research has shown that natural environments can restore our mental abilities. In Japan, patients are encouraged to “forest-bathe”, taking walks through woods to lower their blood pressure.
These health benefits apply to the workplace as well. Rachel Kaplvin, a professor of environmental psychology, has spent years researching the restorative effects of natural environment. Her research found that workers with access to nature at the office - even simple views of trees and flowers - felt their jobs were less stressful and more satisfying. If low-tech offices can potentially benefit the brains and improve the mental health of employees then, fine, bring on the cottages.
1.The writer mentions the two nineteenth-century cottages to show that _________
A.Twitter is having a hard time
B.Old cottages are in need of protection
C.Early settlers once suffered from a dry climate in Montana
D.Internet companies have rediscovered the benefits of low technology
2.Low technology is regarded as something that __________
A.is related to nature B.is out of date today
C.cosumes too much energy D.exists in the virtual world
3.The writer’s attitude to “low technology” can best be described as __________
A.Critical B.positive
C.worried D.doubtful
4.What can be the best title for the passage?
A.Past Glories, Future Dreams
B.The Virtual World, the Real Challenge
C.High-tech Companies, Low-tech Offices
D.The More Craftsmanship, the Less Creativity
