这是一篇说明文。文章介绍了太阳能聚光灯在家庭使用中的功能范围、安装方式及维护策略。

【1】考查上下文逻辑关系。第一段第一、二句提到…There are many ways to use them around your home's exterior as well.（聚光灯不仅能在音乐会和百老汇演出中使用，而且可以在家中使用以防止入侵者或者炫耀自己的花艺）,且该段最后一句提到“Learning the advantages of this option will help you decide whether they are right for your home.”了解这个选项的优势将能帮助您确定是否适合自己的家。由此可知，空处为假设读者决定需要安装聚光灯的情况，G项提到If you should decide to use them, consider installing solar spot lights（如果你决定使用聚光灯，那就考虑装太阳能聚光灯吧）。G项起承上启下的作用。故选G。

【2】考查上下文逻辑关系。第二段第二句提到“Since they are operated solely using power from the sun, they will save you money and help the environment over time.”（这些太阳能聚光灯只使用来自太阳的能量，它们将节省你的钱，而且会随着时间的推移帮助环境的改善。）且最后一句提到“购买太阳能聚光灯不需要大量的前期投资”。由此判断，太阳能聚光灯的使用不仅对环境很友好，而且成本也不高。F项提到In addition, they are not particularly expensive to purchase either（另外，购买太阳能聚光灯也不是很贵）。F项起到承上启下的作用。故选F。

【3】考查段落中心句。分析第三段内容可知，空处需选择该段的中心句。第三段提到安装太阳能聚光灯时不需要直接供电，因此无需进行布线，而且可以安装在房子的任何地方。B.项提到They are extremely easy to install（安装太阳能聚光灯极其简单）符合该段的主要内容，故选B。

【4】考查上下文逻辑关系。第四段第一句提到“Solar spot lights are very safe to use, as well.”（太阳能聚光灯也非常的安全）后文中You can confidently place them near a swimming pool提到“甚至可以放心地安装在游泳池或者水源附近”，由此可判断太阳能聚光灯是没有触电的风险的。E项Again, they need no wiring, so there is no risk of electrical shock（太阳能聚光灯不需要接线，因此安装的过程中不会有电击的风险）。E项起到承上启下的作用。故选E。

【5】考查段落中心句。根据最后一段内容可知“You should wipe them regularly with a damp, soft cloth…”只要定期用湿抹布擦拭聚光灯就可以清除灰尘和污垢，而且电池的使用寿命也很长。由此可判断，太阳能聚光灯的后期使用维护非常的简单。A项Finally, they are easy to maintain（最后，维护方式也非常简单）符合该段的主要内容。故选A。

七选五题型主要考查上下文的理解与推断，虽然文章整体难度一般低于阅读理解，但是却给很多同学造成了很大的心理障碍。七个选项中选五个，比四个选项中选一个，感觉干扰性更大，很大同学在做这个题目时，总有一种眼花缭乱、心烦气躁的感觉，致使往往正确率不高。在这里提醒同学们，首先要克服心理障碍，同时要注意方式方法。其次，注意设空前后的句子，因为这些句子之间是顺承和联系的，所有一定要联系和理解上下文的语境。如第二题，可根据前后文提到的save you money（节省钱）和do not need a large upfront investment（不需要太大的前期投资）可判断空处应选择一项与费用相关的选项。故选F。
