Question

【题目】 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 (金属) 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 (太阳能) 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.
