Sun Power
People who buy solar panels (嵌板）for their home hope to help the environment and save some money. But they end up with large metal boxes on their roof. Tesla, a car company, solved the problem. The solution is the Solar Roof. It is a series of tiles (瓦) made to look like traditional roofing material while using the power of the sun. Tesla developed it with SolarCity, a longtime provider of solar panels. It is now available to the public.
Talking Tech
Echo gives users the ability to talk to their tech. Apple’s Siri and Microsoft’s Cortana do that too. But in many ways，Amazon’s version，Alexa, which is built into Echo，is more powerful. Alexa has grown since it was put on the market in 2014, and today, you can use it to turn on the lights, order a pizza, and more. Echo costs $ 180. Amazon recently developed a junior version, the $ 50 Echo Dot.
Spin and Roll
Goodyear is reinventing the wheel. It introduced its Eagle 360 spherical tire (球形轮胎) in March, 2016. The tires allow cars to move in many directions, including sideways, and at angles to handle slippery surfaces. The key is magnetic levitation (磁悬浮). Tires are fixed to cars, but Eagle 360s float beneath them. They’re meant for self-driving cars of tomorrow.
Cycle Safety
Jeff Woolf had a serious bike crash. If he hadn’t been wearing his helmet, he would have been badly hurt. He wondered why so many riders didn’t wear helmets. That turns out it was mostly because helmets were big and hard to carry around. Woolf, an engineer, came up with Morpher. The helmet is made from interwoven plastics (交错编织的塑料). It is strong, but it’s also flexible enough to fold almost totally flat. That makes it easy to carry. Morpher is priced at $ 119.

【答案】
【1】B
【2】B
【3】D
【4】B
【解析】此文为应用文，文章主要介绍了四项新发明。
【1】细节理解题。根据第一段It is now available to the public.可知solar roof 已经上市，被公众使用，所以B正确。
【2】细节理解题。根据文章第二段and today, you can use it to turn on the lights, order a pizza, and more.可知我们可以利用Alexa来开灯，点外卖等，即利用声音操控高科技。
【3】细节理解题。根据文章第三段最后一句话They’re meant for self-driving cars of tomorrow.可知这种轮胎是为无人驾驶汽车准备的，所以D正确。
【4】细节理解题。根据文章最后一段It is strong, but it’s also flexible enough to fold almost totally flat. That makes it easy to carry.可知Morpher，可弯曲，容易折叠，容易携带，所以B正确。
文章主题和中心思想的阐述往往需要大量细节信息的支持，这些细节对于理解全文内容至关重要，同时也是归纳和概括文章中心思想的基础。命题人往往会要求考生根据不同的要求阅读文章，以获得某些特定的信息，或准确地寻求所需的细节，并对细节进行直接或间接辨认和理解。文章细节的理解可以细化为：（1）一一对应型。答案与题目在表达形式和意义上直接吻合，一一对应，一目了然。属于浅层次的阅读试题，分数比例较少。（2）语言转述型。这是一类间接事实细节题，答案与题目在意义上从分运用了词义之间的转述关系，即正确选项是原文有关词语和句子的另类表达。属于中档难度题，分数比例较大。（3）语意理解型。这是一类深层事实细节理解题，答案与题目之间存在着一定的逻辑联系，这种联系需要建立在事实的基础上通过上、下文来进行判断、分析、归纳和整合，才能得出正确答案。属于较高难度的事实细节题。（4）是非辨别型。这是一类综合事实细节题，出题形式常常是“三正一误”(三项正确，只有一项不符合原文内容)或“三误一正”（三项错误，只有一项符合原文内容)。（5）事实排序型。这是一类运用多项事实进行排序的事实细节题，要求根据动作发生的先后顺序、时间顺序或者句子之间的逻辑关系，找出时间发生，发展的正确顺序。
本题的四题解为细节理解题。其中第一题为语言转述型。原文是It is now available to the public对应选项It is currently on the market.第二题为语意理解型。根据根据文章第二段and today, you can use it to turn on the lights, order a pizza, and more.可知我们可以利用Alexa来开灯，点外卖等，即利用声音操控高科技。
