If you live in southwest Virginia, don’t be surprised at the sight of a drone(无人机) winging its way, doing airborne delivery over your neighborhood.
On October 20,2019,wing,an American multinational company, began the most advanced trials of commercial drone delivery in Virginia. Residents can now use a smartphone app to order items from Wing partners such as Sugar Magnolia. A Wing drone never sets down at destinations, instead gently lowering the package with a rope outside the customer's door.
Though Wing is the first American company to receive Federal Aviation Administration(FAA)approval to use commercial drones as a widespread service. it is not the only one. On October 22,2019,multinational delivery company UPS, which had also received FAA approval for its drone fleet, announced it would soon begin trial deliveries of goods from health care company CVS. Meanwhile, ridesharing company, Uber, which had partnered with McDonald's, hoped to use its drones to deliver food to hungry customers in San Diego, CA, before the end of 2019. Amazon also plans on testing its trial deliveries of goods in a yet-to-be-determined location in the upcoming months.
Every company's drones can carry packages weighing up to five pounds, and the series of trial are hortative, but widespread drone delivery still has many challenges. These include basic issues like finding places for drones to land, reducing noise pollution, and even ensuring the drones don't run into each other while airborne.
To help sped up the process, NASA announced the Urban Air Mobility Grand Challenge. The competition challenges airspace service providers to find creative solutions to the issues, so that drone deliveries can become a reality soon. “We are moving fast,” said NASA Administrator Jim Bridenstine. “We want to see by 2028 at least one city--maybe more than one--have the ability to control hundreds of drone delivery systems. They could be carrying goods, doing thousands of missions every day.”

I had been living with Dino and his family for ten days or so, who lived and worked in the rainforest. They were the “bad guys”, burning much of the western Amazon to tun it into cattle farms. They were also some of the nicest and warmest hosts. They are a family trying to survive in a very tough environment through hard work. Their view and understanding of the problems the Amazon faces are different from mine. I see the Amazon as an extraordinary valuable life that should be treasured and protected at all costs-the world needs it, and we all need it. However, the Dinos see the Amazon as a vast, lasting resource that feeds them. After talking extent win them, I realized their respect for it was as deep as my own: they just saw it very differently.
Cattle farming in the Amazon is perhaps mainly responsible for the fires we are seeing now. It is an industry of cutting forest, burning it and turning it to cattle farms. Fires spread throughout the Amazon every year as a result of that practice. Putting cattle on the land means replacing trees with animals that produce damaging levels of greenhouse gases. This is just about the most stupid thing humans can do.
One morning after a fire, I returned to the land. I felt as though I had seen the blue smoke from those blackened tree trunks that remained upright, which are memorials to human stupidity.
The problems the Amazon faces are perhaps more complex now than ever before, but they are curable. We need to decide where and how we appoint and apply values based on sensible economic models that favor both the farmer and the forest. One of the issues facing the Brazilian Amazon now is a loosening of rules by the current administration which has opened up more land for deforestation(毁林) and burning. This could be disastrous, both for the Amazon and the rest of the world.
1.What does Paragraph 2 mainly talk about？
A.The consequences of cattle farming. B.The main cause of forest fires.
C.The causes of greenhouse gases. D.The importance of cattle farming.
2.How did the author feel when returning to the land after a fire?
A.It helped the author recall his memory about the land.
B.It reminded us of our foolishness of destroying the land.
C.It's not surprising to see the land destroyed by the fire.
D.It's amazing to see the trees keep straight after the fire.
3.Which of the following statements is true?
A.The writer and Dino respected the Amazon equally in different ways.
B.Cattle farming is not to blame for the fires happening in the Amazon.
C.The problems the Amazon faces are more complex and can't be solved.
D.The Dinos are considered to be bad for burning the forest to make a fortune.
4.What should the Brazilian government do to solve the Amazon problems？
A.Prevent the deeds of burning. B.Offer more land.
C.Take stricter measures. D.Appoint economic models.
Last year, Wolf Cukier, who is 17 years old, spent his summer vacation as few other rising seniors have：he helped discover a planet-TOI 1338b, the newly identified world orbiting two stars which are more than 1, 300 light years away.
Last July， just after he finished his junior year at Scarsdale High school in Scarsdale, New York, Wolf started an internship(实习期) at NASA's Goddard Space Flight Center in Greenbelt, Maryland.
During the first week of the internship, as be combed through data that had been flagged by citizen-scientists. he fixed attention on s system that included two orbiting stars. He identified a body in that system that was later proved as a planet about 6.9 times as large as Earth. while knowing this inspiring discovery, his colleagues immediately gave the system a name, TOI 1338b.
According to scientific research, any dip in the brightness of a single star is a good indication that a planet has crossed in front of it. However, TOI 1338b was particularly complicated because it involved two stars-a large star ere the planers track was easy to detect, and a smaller one where the planet's track was so small that it was not observable.
Many people think that wolf is a lucky dog, but as a matter of fact, it is not just a coincidence. When he studied in Junior High School, he had shown great passion on astronomy and was devoted to studying it. Wolf plans to study astrophysics(天体物理学) when he starts college in September.

Due to the outbreak of COVID-19, schools across the country have put off opening. For more than two months, students have been taking online classes at home.
Su Hua: I am required to attend online classes every day and I always listen attentively to what teachers instruct. As to questions put forward by teachers, I try to answer and talk to myself, even when teachers can’t hear my voice. I can complete daily online homework as expected. Sometimes, food, or other things distract me, but I can put them away. I feel content with my everyday progress. I think the best way to learn efficiently during the extended holiday is to manage myself effectively. |
Li Jiang: My parents have said I attend online classes every day, but do not pay attention at all. I can’t resist the temptation to play games with smartphones. Thus, it is difficult for me to finish assignments on my own. Last week, when I went back to school to take the first exam, the results were not satisfying. I feel regretful for wasting so much time but I couldn’t control myself. The root cause may lie in lack of self-discipline. |

Is Loneliness a Health Epidemic (流行病)？
Over the last twenty years, more and more studies reveal increasing numbers of people experience loneliness regularly. In the face of such a situation, earlier this year, Britain appointed its first “minister for loneliness”, who is charged with dealing with what the Prime Minister called the “sad reality of modern life”.
Public-health leaders immediately praised the idea-and for good reason. In recent decades, researchers have discovered that loneliness left untreated is not just psychically painful; it also can have serious medical consequences. And numerous studies have linked loneliness to heart disease, cancer, depression, diabetes and suicide. Vivek Murthy, the former United States surgeon general, has written that loneliness is associated with a reduction in life span similar to that caused by smoking 15 cigarettes a day and even greater than that associated with obesity.
Anxiety about loneliness is a common feature of modern societies. Today, two major causes of loneliness seem possible. One is that societies throughout the world have embraced a culture of individualism. More people are living alone, and aging alone, than ever. Liberal social policies have turned workers into unstable free agents, and when jobs disappear, things fall apart fast. Labor unions, civic associations, neighborhood organizations, religious groups and other traditional sources of social unity are in steady decline. Increasingly, we all feel that we’re on our own.
The other possible cause is the rise of communication technology, including smartphones, social media and the Internet. A decade ago, companies like Facebook, Apple and Google promised that their products would help create meaningful relationships and communities. On the contrary, we’ve used the media system to deepen existing divisions, at both the individual and group levels. We may have thousands of “friends” and “followers” on Facebook and Instagram, but when it comes to human relationships, it turns out there’s no choice but to build them the old-fashioned way, in person.
But is loneliness, as many political officials and experts are warning, a growing “health epidemic”? I don’t believe so, nor do I believe it helps anyone to describe it that way. Social disconnection is a serious matter, yet — if we arouse a panic over its popularity and impact, we’re less likely to treat it properly.
In places like the United States and Britain, it’s the poor, unemployed, displaced and migrant populations that suffer most from loneliness. Their lives are unstable, and so are their relationships. When they get lonely, they are the least able to get adequate social or medical support.
I don’t believe we have a loneliness epidemic. But millions of people are suffering from social disconnection. Whether or not they have a minister for loneliness, they deserve more attention and help than we’re offering today.
