The 2020 Summer Olympics in Tokyo has been put off because of the COVID-19. To welcome the great event, Japan has made 5, 000 medals for the winners. But these Olympic medals are very special. They are all made out of recycled electronic devices(电子设备).

One goal of the Tokyo Olympics is to avoid using too many natural resources, so that the games are environmentally friendly. As part of this goal, the organizers decided to make all of the Olympic medals out of metals recycled from old electronic devices.

You might not know it, but almost all the electronic devices are made with small quantities of precious metals (贵金属), like gold and silver. But collecting enough of these metals to make 5, 000 medals was a huge challenge. That's because the quantity of metals in each device is tiny. It would take about 20,000 cell phones to get just 1 kilogram of gold.

Beginning in April 2017, organizers placed collection boxes around the country, and asked people to turn in their old electronic devices for the Olympic medals. Soon people began to fill up the boxes, turning in smartphones, digital cameras, and laptops. At first, the collection work went slowly, but soon more and more areas began to turn in electronic devices, And 1,621 local governments also helped with the collection work. The Japanese mobile phone company NTT Docomo collected 6.21 million used cell phones. In all, around 71,667, 600 kilograms of electronic devices were collected.

Then came the job of breaking those phones down into smaller pieces. This is a tricky(棘手) job. It is also likely to cause danger, because some of the metals and other things that go into electronic devices aren’t safe for people to touch or breathe. That's why it's not a good idea to try something like this at home. Once the devices were broken down, the metals had to be carefully separated out.

On July 24, 2019, the design for the awards was announced. And by the end of March this year, the organizers had reached their goal.

1.Why does the author say the Tokyo Olympic medals are special?

A.They can be recycled into other products. B.They are small in size and large in number.

C.They are made out of old electronic devices. D.They are green and seem environmentally friendly.

2.What is the main purpose of Paragraph 4?

A.To show the difficulty of the collection work.

B.To thank those who helped with the collection work.

C.To stress the importance of many people working together.

D.To give information on how the collection work was done.

3.What does the author think of the break-down work?

A.Dirty and tiring. B.Hard and dangerous.

C.Boring but rewarding. D.Interesting but challenging.
