答案：1-4.ABDA
解析：本文是一篇说明文,介绍了一款可以和智能手机连接在一起,用于追踪人或东西的软件。
1.词义猜测题。根据第一段中的"Then you start wandering around and clicking on the panic button on your car keys so the alarm goes off. It can be frustrating, especially on a hot and sunny day."可知按下汽车钥匙上的报警按钮让警报器鸣响,尤其是在炎热晴朗的天气下,让人非常烦恼。由此推知frustrating意为“令人沮丧的”,故选A。
2.细节理解题。根据第二段可知GPS很贵,现在有一种设备不会花费很多钱,即TrackR Bravo,因此它会是一个更好的选择。故选B。
3.细节理解题。由文章倒数第二段第一句"You can connect it to your keys, briefcase, wallet, your latest tech gadgets and anything else you don't want to lose."可知TrackR Bravo可以和不同的东西连接在一起,故选D。
4.推理判断题。本文介绍了一款可以和智能手机连接在一起的应用程序,与科技有关,故选A。
四、
答案：①-⑤BCGDF
解析：①在说明文文体中,第一段一般起到总领全文的作用,接着文章提出了五个保护视力的建议,故第一段中需要一句总起全文的句子选项为总结性句子。故B项正确。
②文中第三段提到可以戴墨镜阻挡紫外线在段末处需一句总结性语句。C选项中的代词they指代的是前文中提到的sunglasses,故C项正确。
③文中第四段提到2/3的美国人使用电脑的时间超过了7小时。 而文中给出第3个建议是让眼睛休息一下,说明长时间使用电脑对眼睛是有损伤的。G选项中提到的"this frequent eye activity" 指的是长时间使用电脑。故G项正确。
④根据第五段内容,维生素C、E都能保护人们的视力,提高眼睛的力量,可以看出该段的关键词为vitamin。故D项正确。
⑤文中最后一段提到"While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk"有一些人会遵守医嘱正确地佩戴隐形眼镜, 但仍有一部分没有遵守医嘱的人,他们就可能面临视力上的危害。 因此要时刻遵守医嘱,故F项正确。
