They’re neither medical workers in close contact with the novel coronavirus nor government officials who receive the 1. (late) updates of the situation — yet they’re keeping us 2. (inform)of the development of the epidemic. They are the media, and their eyes are far-seeing.
Zhu Xingxin is one such member: a 3. (photograph) with China Daily. Having putting on protective gear (装备) like the doctors, he visited Tongji Hospital in Wuhan on Feb 3 to report on the lives of medical workers.
The eyes of the media are not just here to see, but 4. (examine). On Feb 9, for example, a bus in Wuhan carrying severely ill patients 5. (catch) in traffic with no one guiding them and no hospitals claiming them. The incident was witnessed by Global Times journalists and was soon reported online. It ended with all the patients 6. (settle) properly in hospitals and officials in charge being held responsible. But it’s possible 7. without journalists this incident would never have been exposed.
“I do hope that by writing about 8. (they) stories, I’m helping things change for 9. better.” said Li Xueqing, a China Daily journalist. Indeed, the media is like a pair of eyes watching out 10. us as they report on the world’s most important news.

Why Do Brides Wear White
In many societies the color white has been associated with purity and virtue, and that is one reason why some brides choose to wear white, especially in the West. Usually, you will hear that brides wear white because “it’s a tradition”. But, historically, white was not the only color considered for wedding dresses. 1.
For many centuries in Western societies, wedding dresses had different colors. 2. Brides tended to buy a wedding dress that could be worn again, or they simply wore the best dress they already owned. And white is not practical: it is difficult to keep clean and is therefore not ideal for many situations or for repeated wear.
Many brides chose to wear dresses of other colors for their wedding and beyond. 3. They do so largely thanks to a trend that started with Queen Victoria’s 1840 wedding to Prince Albert.
4. Although not in as many different media as we have now, they still had a tendency to be trendsetting. So Victoria chose to wear a white gown (女礼服)—reportedly to show off the fine detailed Honiton lace produced by the British lace industry, which was depressed at the time. Her fashion choice was widely reported in newspapers and magazines. 5. Eventually, the trend of a white wedding gown spread across all economic levels and it was strengthened as “tradition” in the 20th century.
A.So why do so many of today’s brides wear white?
B.But why are brides so particular about their dresses?
C.Royal weddings in those years received a lot of reporting.
D.It reflected the growth of the wedding industry at that time.
E.It soon influenced domestic and international wedding trends.
F.In fact, other colors were chosen far more frequently than white.
G.This was for reasons of being practical as much as anything else.
Is there a link between social media and depression? Do Facebook and Instagram have a negative impact on your mental health? It’s complicated.
Sometimes, looking through Instagram just makes you feel bad. You try not to envy your friends, but they always seem to be traveling somewhere cool, eating something fancy, or looking cute in perfect just-rolled-out-of-bed hair. On the other hand, there are times when you laugh at funny memes (表情包), catch up with old friends, and feel happy to belong to fun social media communities, Clearly, social media isn’t all bad.
People are increasingly suspect that there’re the potential problems of social media. Things like cyberbullying, screen addiction, and being exposed to endless filtered images (美颜) that make it impossible not to make comparisons between yourself and others often make the news. In July, a big study came out in the journal JAMA titled “Association of Screen Time and Depression in Adolescence.” This big headline seems to confirm what a lot of people have been saying-screen time is horrible for young people.
The study followed over 3800 adolescents over four years as part of a drug and alcohol prevention program. Part of what the investigators measured was the teens’ amount of screen time, including time spent on social media, as well as their levels of depression symptoms. One of their main findings was that higher amounts of social media use were associated with higher levels of depression. That was true both when the researches compared between people and compared each person against their own mental health over time.
Case closed? Not so fast. Before we end the debate once and for all, let’s take a closer look at this and other studies. Let’s ask ourselves: what exactly is the relationship between social media use and depression? It turns out there are several warnings.

B.Depression is related to social media use.
C.It is not easy to tell reasons for depression.
D.Social media use contributes to mental health.
4.What’s the best title of the text?
A.How to reduce depression?
B.Shall people reduce screen time?
C.Does social media cause depression?

Pigeons (鸽子) may be considered mice of the sky, but some scientists have found greater value in these urban birds: the blueprint for a new generation of flying machines.
Birds can transform the shape of their wings by fanning out their feathers or moving them closer together. Those adjustments allow birds to cut through the sky more flexibly than rigid drones (无人机). Now, using new insights into exactly how pigeons ‘joints control the spread of their wing feathers, researchers have built a robotic pigeon. This research paves the way for creating more light aircraft, says Dario Floreano, a roboticist in Switzerland not involved in the work.
“What’s really cool about this robot is that you can make adjustments in a robotic wing that you could never do when studying flight in a bird”, says David Lentink, an engineer and biologist at Stanford University. A controllable robotic pigeon solves that problem. In flight tests, Lentink’s team observed that bending only the fingers of one wing eased the robot into a banked turn-offering the first evidence that birds may sometimes use just their fingers to direct in flight. In a second study, Lentink’s group used their robotic wing design to confirm another insight into bird flight: how gaps are prevented from forming between feathers on extended wings.
This is the best set of robotic wings yet for testing how birds adjust their flight feathers to move through the air, says Tyson Hedrick, a biomechanist. But “there’s plenty of room for improvement.” For instance, a future flying robot could include a shoulder joint to investigate how waving a bird’s wings up and down influences flight, he says.

B.People can’t make adjustments in birds’ wings.
C.It is difficult for pigeons to make a banked turn.
D.Pigeons fail to control the spread of their wing feathers.
4.Where does the text probably come from?
A.A travel journal.
B.A travel brochure.
C.A science fiction.
D.A science magazine.
I remember doing the household chores to help my mother when I was nine. I hated changing the vacuum cleaner (真空吸尘器) bag and picking up things the machine did not suck up. Twenty years later, in 1978, with this lifelong dislike of the way the machine worked, I decided to make a bagless one.
Easier said than done, of course. I didn’t realize that I would spend the next five years perfecting my design, a process that resulted in 5,127 different prototypes (样机). By the time I made my 15th prototype, my third child was born. By 2,627, my wife and I were really counting our pennies. By 3,727, my wife was giving art lessons for some extra cash, and we were getting further and further into debt. These were tough times, but each failure brought me closer to solving the problem.
In the early 1980s, I started trying to get licensing agreements for my technology. The reality was very different, however. The major vacuum makers had built a business model based on the profits from bags and filters (滤网). No one would license my idea, not because it was a bad one, but because it was bad for business. But soon after, the companies that I had talked with started making machines like mine. I had to fight legal battles on both sides of the Atlantic to protect the patents on my vacuum cleaner.
I was still in financial difficulties until 1993, when my bank manager personally persuaded Lloyds Bank to lend me $1 million. Then I was able to go into production. Within two years, the Dyson vacuum cleaner became a best-seller in Britain.
Today, I still embrace risk and the potential for failure as part of the process. Nothing beats the excitement of invention,
1.What drove the author to make a bagless vacuum cleaner?
A.His willingness to help mom.

2.What does paragraph 2 mainly tell us?
A.The help from the author’s wife.
B.The financial problems of the family.
C.The tough process of the new invention.
D.The procedures of making a bagless cleaner.
3.Why did the companies refuse to license the author’s technology?
A.They thought they might suffer loss.
B.They considered it not good enough.
C.They faced legal problems themselves.
D.They had begun making such machines.
4.What lesson may the author learn from the experience?
A.Think twice before acting.
B.Failure is the mother of success.
C.Actions speak louder than words.
D.A good beginning makes a good ending.
