Question

    The 2020 summer Olympics will be held in Tokyo next year. Japan has made 5,000 medals for the winners. But this Olympic medals are more special than most----they are made entirely out of recycled electronics.

One new focus of the Tokyo Olympics is to make them “sustainable”----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 metal recycled from old electronics. They needed gold for first place medals, silver for second, and bronze for third. You might not know it, but 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 is 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 2. 2 pounds (1kilogram) 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 smart phones, digital cameras and laptops. By the end, 1,621 local governments had helped out with the collection process. The Japanese mobile phone company NTT Docomo collected 6.21 million used cell phones. In all, around 158,000,000 pounds (71,667,660 kilograms) of electronics were collected.

Then came the job of breaking those phones down into smaller pieces. This is a difficult job. It's also dangerous, because some of the metals and other things that go into electronics 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. By the end of March, the organizers had hit their targets. The opening ceremony for the 2020 summer Olympics will take place in Tokyo on July 24,020.

【解析】

本文为说明文。主要讲述了2020年日本东京奥运会的奖牌是特别的，因为奖牌都是由回收的电子产品制成的，并就金属收集挑战以及人们的工作配合进行了说明。

1.细节理解题。根据文章第一段 But this Olympic medal are more special than most-they are made entirely out of recycled electronics．（但东京奥运奖牌比大多数奖牌更特别，因为它们完全由回收电子产品制成的。）可知，它的制作材料比较特殊，结合选项，故选B。

2.细节理解题。根据文章第二段But collecting enough of these metals to make 5，000 medals is 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 2． 2 pounds （l kilogram） of gold．（但是收集足够的金属来制造5000枚奖牌是一个巨大的挑战，因为每个电子产品装置中的金属量很小，需要2万部手机才能获得2.2磅（1公斤）的黄金，）可知，手机足够制作金牌使用的金属是一个挑战是因为每个装置中的金属量很小。故选C。

3.推理判断题。根据文章第三段Soon people began to fill up the boxes， turning in smart phones， digital cameras and laptops．以及其后列举的数字可推断，日本人踊跃进行电子产品的捐赠，他们也非常赞成收集电子产品。故选C。

4.细节理解题。根据文章最后一段This is a difficult job． It's also dangerous， because some of the metals and other things that go into electronics aren′t safe for people to touch or breathe．可知，把手机拆成碎片的工作很难，也很危险，因为进入电子设备的一些金属和其他东西对人们的触摸和呼吸都不安全。结合选项，故选A。
