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.

To my surprise, father________(点头)his head without saying anything.

One of the most often asked and most controversially(有争议的) answered questions is "What should I do when I meet a blind person?" A quick Google search will turn up plenty of answers, which are quite different from each other. So, obviously, there is no general agreement on what to do when you meet a blind person.

There are no special rules or does and doesn't that can deal with this situation. There is only one principle(原则): Blind people are nothing more or less than people who happen to be blind. As such, it is our own job to take care of ourselves, and we are grateful to no one else for special care or leadership. For we think we are equal（平等的）to normal people.

The best thing to do is nothing. Don't suppose you know what we need. If we do need something, we'll politely let you know.

Forget everything you've heard about the blind even if you consider yourself to be an expert. Blind people have plenty to say about "experts". Especially, forget anything you've heard or read about "Ten Things to Do if You Meet a Blind Person". The advice will probably just cause more embarrassment(尴尬). More of it is made up by sighted people anyway and doesn't necessarily stand for the blind's view.

There is completely no way to second—guess the situation by imposing(强加)any preformed ideas. Even if you've known other blind people, don't think you know what to do with every one of them. The thing that often makes us angry is to hear "It's OK. My mother(sister, cousin, friend)is blind."

Blind people are as different from each other as any two people on this earth. There are no similarities among us that you can depend on. Even the degree of vision, hearing or touch that we use can be very different. Most blind people do have same degree of vision，and even the very few of us who are totally blind may use our touch and hearing very effectively.

A.is a blind person B.hears more clearly than others

C.never asks others for help D.thinks blind people need special care

D.Each person, blind or sighted, is different from anyone else.

3.Which of the following might be the best title for the passage?

A.Never Help the Blind B.Try to Help the Blind

C.Not Every Help Is Good for the Blind D.Learn More about the Blind
