Question

【題目】 Don’t throw away your old phones.You are actually throwing away real gold! Smartphones have many kinds of useful metals. People can recycle them to make new electronics.

But many people may not know this. In Australia alone there are more than 25 million unused mobile phones lying around, The Sydney Morning Herald reported. The gold in these phones can add up to a value of more than $80 million. There are about 2 billion smartphone users around the world, who change their phone once every 11 months on average. So in China, eighty million old phones come along every year.

However, it’s not easy to get the useful things out of the phones. Smartphones have not only useful things but also harmful materials. Guiyu, a small town in Shantou, Guangdong, is one of the world’s biggest dumping grounds for electronic waste, Reuters reported. Many recycling centers in Guiyu simply break the old electronics by hand and don’t think about the pollution it causes. It’s reported that 81 percent of children in Guiyu are harmed by lead poisoning(鉛中毒).

Veena Sahajwalla, a professor at Australia’s University of New South Wales, has made a mini factory. It makes smartphone recycling cleaner and easier. The mini factory is very small and easy to move around. It breaks the phones and automatically(自動地)removes the phone’s useful things. That way, humans do not get poisoned.

Well, have you ever wondered what happens to the old phone after it’s no longer yours? A part of your old smartphone could soon be proudly worn around the neck of one of the world’s top athletes. Organizers of the 2020 Tokyo Olympics say that medals for the event will be made from recycled phones. They will also be made out of people’s thoughts for avoiding waste. They think there is an important message in this for the future.

【解析】

本文主要介紹智能手機包含許多有用的金屬，人們可以回收它們來制造新的電子產品。此外，智能手機還含有有害的物質，對人的身體和環(huán)境會帶來危害。因此，很多人正努力回收利用舊手機。

【1】詞義猜測題。根據(jù)上句中“recycle them to make new electronics”可知，舊手機可以回收利用來制造新的電子器件，但是很多人可能不知道這個，即不知道舊手機可以回收利用。故選A。

【2】細節(jié)理解題。根據(jù)第三段中“the world’s biggest dumping grounds for electronic waste”可知，填埋場是人們存放垃圾的地方。故選C。

【3】細節(jié)理解題。根據(jù)第三段“Guiyu,…is one of the world’s biggest dumping grounds for electronic waste, .... Many recycling centers in Guiyu simply break the old electronics by hand and don’t think about the pollution it causes. It’s reported that 81 percent of children in Guiyu are harmed by lead poisoning(鉛中毒).”可知，貴嶼鎮(zhèn)許多兒童被鉛中毒因為貴嶼鎮(zhèn)被電子垃圾污染了。故選B。

【4】推理判斷題。根據(jù)倒數(shù)第二段“It makes smartphone recycling cleaner and easier. The mini factory is very small and easy to move around. It breaks the phones and automatically(自動地)removes the phone’s useful things.”可知，Veena Sahajwalla的工廠讓智能手機回收更清潔更容易。這個微型工廠非常小，很容易移動，并且自動移除手機上有用的東西。故選項C正確，選項A、D不正確；選項B意為“它每年生產8000萬部智能手機”，文章未提及，故B不正確。故選C。

【5】推理判斷題。根據(jù)最后一段“…medals for the event will be made from recycled phones. They will also be made out of people’s thoughts for avoiding waste. They think there is an important message in this for the future.”可知，為了避免浪費，奧運會的獎牌將由回收的手機制成，這對未來有著重要的意義。由此說明電子廢棄物回收利用具有重要意義。故選D。

本題的第1小題是詞義猜測題。詞義猜測題是閱讀理解中常見的一種題型，所猜測詞匯可以是生詞，也可以是熟詞新義，還可以是人稱代詞的指代內容。詞義猜測題主要考查考生根據(jù)上下文推測詞義和語義的能力，突出考查對語境的分析和把握能力。本題利用上文語境來猜測詞意。猜測任何詞義都離不開上下文，所以要借助上下文對需要猜測的詞或短語進行合乎邏輯的推測。
