Question

【題目】 During the past year, lots of great technologies have come into our lives, such as driverless cars and AI. What will come next? Forbes has listed a few breakthroughs (突破) that may have an influence in the new year.

	5G Internet How fast is your mobile phone? After 3G and 4G, 5G is on the way. According to Science Daily, 5G tests are expected to start as early as 2019 in the US and by 2020 in the UK. China has already tested 5G in some parts of Beijing and Hebei.
	3D metal (金屬) printing 3D printing is not new. It first appeared in the 1990s. But it hasn’t been widely used in our daily life. 3D printers are expensive, costing thousands of dollars for each. However, there are new 3D printers that can print metal. HP can print some small metal parts for cars, such as key ring.
	Green and renewable energy As many countries pay much attention to pollution, electric cars and solar energy (太陽能) might become more popular. More carmakers, including Audi and Volvo, will have more electric powered cars on the road. And by 2025, almost every sixth car sold in the world will be electric.

【解析】

本文主要介紹科技給我們的生活產(chǎn)生了很大影響，《福布斯》列出了3項(xiàng)可能在新的一年產(chǎn)生影響的新科技。

【1】細(xì)節(jié)理解題。根據(jù)原文“According to Science Daily, 5G tests are expected to start as early as 2019 in the US and by 2020 in the UK.”可知英國(guó)的5G網(wǎng)絡(luò)測(cè)試將會(huì)在2020年啟動(dòng)，故選B。

【2】細(xì)節(jié)理解題。根據(jù)原文“But it hasn't been widely used in our daily life. 3D printers are expensive, costing thousands of dollars for each.”可知3D打印技術(shù)之所以沒有被廣泛應(yīng)用是因?yàn)樘�貴了，故選A。

【3】推理判斷題。根據(jù)原文“As many countries pay much attention to pollution, electric cars and solar energy (太陽能) might become more popular. ”和“More carmakers, including Audi and Volvo, will have more electric powered cars on the road.”可知大量國(guó)家關(guān)注污染問題，electric powered cars將被更多汽車制造商生產(chǎn)使用，這種綠色新能源車的大量使用可以保護(hù)環(huán)境，其他選項(xiàng)原文均未提及。故選C。

【4】推理判斷題。這篇文章是介紹新科技的，由此可推斷會(huì)出現(xiàn)在雜志的科學(xué)版面，故選D。
