Question

【题目】 If you’re looking to buy a gift for your children, why not keep up with the trend and get the best hoverboard?

What is a Hoverboard?

A hoverboard is a two-wheeled personal transportation device. It’s electrical, portable and became highly popular in 2015 in reference to a popular 1980’s movie. Typically, this self-balancing device operates like a powered skateboard.

How Does a Hoverboard Work?

The device may have many designs, but the mechanism itself isn’t complicated. Basically, a standard hoverboard contains:

Battery: stores the electrical power. Almost all hoverboards use a high-watt lithium-ion battery.

Gyroscope (one for each wheel): allows riders to tilt (倾斜) the hoverboard while maintaining balance and adjusting their direction.

Motor (one in each wheel): provides the power to the wheels to keep the rider balanced and upright.

Logic board: functions as the hoverboard brain. It processes data — your speed, tilt, etc. — and sends information to the motors. This unit controls the power of the board so riders can adjust their speed.

All the above components work together to control the power and tilt of the hoverboards so the rider is balanced, upright and moving at a controlled speed.

Why Buy a Hoverboard?

Undoubtedly, hoverboards are cool. You’ve probably seen kids riding one around the house. They’re a phenomenon and everybody wants in. So, why deny your kids and prevent them from being part of this trend?

Where is a hoverboard legal?

Despite their wild popularity, hoverboards have yet to become “street-legal”. Currently, some places prohibit anyone under 16 from using these devices, and hoverboards are banned in academic institutions and public places, like campus buildings, parks, shopping malls and subway stations. Some places have also put speed limits on the devices and restricted their use to bike paths. However, open areas — including your yard — are free of these restrictions.

Answer 1

【答案】

【1】D

【2】C

【3】B

【解析】

这是一则推荐类的广告。文章主要介绍了悬滑板（平衡车）的相关情况。

【1】细节理解题。由Logic board 部分中的It processes data — your speed, tilt, etc.— and sends information to the motors. This unit controls the power of the board so riders can adjust their speed.可知，它处理数据——你的速度、倾斜度等——并将信息发送给电动机。这个装置控制着滑板的力量，所以骑手们可以调整他们的速度。由此我们可以判断logic board可以接收数据，并发出指令。故选D项。

【2】细节理解题。由最后一段中的Currently, some places prohibit anyone under 16 from using these devices, and hoverboards are banned in academic institutions and public places, like campus buildings, parks, shopping malls and subway stations.可知，目前，一些地方禁止16岁以下的人使用这些设备，学术机构和公共场所也禁止使用悬滑板（平衡车），比如校园建筑、公园、购物中心和地铁站。选项A校园，B公园，D购物中心都被排除。故选C项。

【3】推理判断题。由第一段中的If you’re looking to buy a gift for your children, why not keep up with the trend and get the best hoverboard?可知，如果你想给你的孩子买礼物，为什么不紧跟潮流，买最好的悬滑板（平衡车）呢？由此可知，这篇文章是帮大家推荐一款给孩子的礼物。故选B项。

解目的意图类的推理判断题，一般是结合首段或者末段，就可以找到文章的目的意图。如第3小题，问文章的目的是什么，我们结合第一段中的If you’re looking to buy a gift for your children, why not keep up with the trend and get the best hoverboard?可知，如果你想给你的孩子买礼物，为什么不紧跟潮流，买最好的悬滑板（平衡车）呢？由此可知，这篇文章是帮大家推荐一款给孩子的礼物。故选B项。
