The Tokyo Summer Olympics is going green. The 5,000 medals Japan has made are more special than most.
One novel focus of the Tokyo Olympics is to be“sustainable”—to avoid using too many natural resources, so that the games are easy on the environment. As part of this goal, the organizers decided to make all of the Olympic medals out of metal recycled from old electronics.
Almost all electronics are made with small amounts of "precious metals", like gold and silver. But collecting enough of these metals to make 5,000 medals was a huge challenge. That's because the amount of metal in each device is tiny. It would take about 20,000 cell phones to get just 1 kilogram of gold.
Beginning in April 2017, the organizers placed collection boxes around the country, and asked people to turn in their old electronic devices. Soon people began to respond to the initiative, turning in smartphones, digital cameras, hand-held games, and laptops. At first, collection went slowly, but soon more and more areas began to take part. By the end, 1,621 local governments had helped out with the collection process.
Then came the job of breaking those devices down into smaller pieces. After being taken apart and sorted, the small electronics were smelted (熔炼) to get all the gold, silver, and bronze elements. This is a tricky job, which calls for careful attention and good skill. It's also dangerous, because some of the metals and other things aren't safe for people to touch or breathe.
By the end of March, 2019, the organizers had hit their targets of getting enough metal for the medals. They had collected around3xkilograms of gold, 4,100 kilograms of silver and 2,200 kilograms of bronze. And now all the 5,000 medals are available for the would-be winners.

The unique ocean animals were discovered by a team of scientists led by Dr. Christine Dudgeon from Australia’s University of Queensland during a 12 year global conservation study.
The newly-found sharks have evolved (进化) to survive in low oxygen environments, enabling them to hunt during low tides. The researchers believe their ability to use their fins (鰭) to walk affords the sharks a remarkable edge over the smaller animals they try to hunt. “While they are super hunters in their shallow habitat, the tiny sharks present no threat to people,” says Dudgeon. “At less than a meter long on average, they’re incredibly cute little animals that do not look like sharks at all,” she adds.
A DNA analysis of skin samples from the live fish suggests that walking sharks broke away from their original population and became a distinct species about nine million years ago. Though that may appear to be a long time ago, it is relatively recent given that sharks have been around for more than 400 million years. In fact, Dudgeon and her team believe walking sharks are the youngest kind of sharks on Earth!
The researchers say that the sharks’ small numbers and small habitat make them extremely vulnerable (易受伤害) to natural disasters and overfishing. They are currently on the Nature Red List, which lists species at risk. Dudgeon and her team believe sensible conservation management plans are urgently needed to protect the walking sharks and other endangered animals from further threats.

D.The DNA samples of the sharks.
3.What should be done without delay according to Dudgeon and her team?

C.Changing the sharks’ living environments.
D.Adopting necessary measures to protect the sharks.
4.In which column of a website can we read the text?

C.Education. D.Geography.
Long Island’s hiking routes offer an escape for family time or your own mental or physical health. There’s lots to see, so open your senses because it's a relaxing thing to do in a stressful time.
Sagamore Hill, Oyster Bay

A lady placed her clock at the bed, and every day she found herself awaking by a long sound. She arose at once, and felt better all day for her early rising. This lasted for weeks. The alarm clock faithfully do its duty. But, after the time, the lady grew tired of it. When she heard its sound, she merely turned over in bed, and was slept again. The clock spoke just loudly as ever; but she did not hear it.
So it is of conscience. If we will obey its voice, even in the tiny things, we can always hear it, clearly and strong. But if we allow us to do that may not be quite right, we shall grow more and more sleepy, until the voice of conscience has no longer powers to wake us.
阅读小面短文，在空白处填入1个适当的档次或括号内单词的正确形式。
By now it’s almost common knowledge that spending time in nature is good for you. Areas with 1.(many) trees tend to be less polluted, so spending time there allows you to breathe easier. Spending time outdoors contributes to good health, with blood pressure and stress 2.(reduce), and seems to motivate people 3.(exercise) more.
A survey showed that people 4.spend 2 hours in nature — either all at once or totaled over several shorter 5.(visit) — were more likely to report good health and psychological well-being than those with no nature 6.(expose). Remarkably, the researchers found that less than two hours offered no significant benefits. The two-hour benchmark (临界值) 7.(apply) to men and women, to older and younger folks and so on. Even people8.long-term illnesses or disabilities benefited from time 9.(spend) in nature — as long as it was at least 120 minutes per week.
While the findings are based on 10.tremendous number of people, scientists caution that it’s really just a correlation. Nobody knows why or how nature has this benefit or even if the findings will stand up to stricter investigation.
