【解析】本文是说明文。主要讲述了人们在购买户外太阳能灯时需要注意的几个问题。

1.B

考查对上下文的理解和推理判断能力。由本文主题句“Does your area receive enough direct lighting?”和该空后的相关内容可知。这里是说你所住的地方要有足够的直射阳光，否则这些太阳能灯就无法正常发挥作用。故选B。

2.E

考查对上下文的理解和推理判断能力。本段主要是讲价格高一些的太阳能灯质量会更好，所以人们在购买的时候最好一次性地选购那些价格较高的太阳能灯，故用E项内容作小标题最恰当了。

3.F

考查对上下文的理解和推理判断能力。由该空前后的“,it's best to buy more expensive lights of high quality. ”和“At least you should know the difference between a $10 light and a $45 light.”可知，作者并不是说要人们把钱都花在那些价格昂贵的灯上，但起码应该明白十美元的灯和四十五美元的灯之间的差异。故选F项。

4.A

考查对上下文的理解和推理判断能力。由本段标题“Buy lights that require less installation”和该空后的“You don't need to buy lights that require half an hour each to plant into the ground”可知，作者在此建议人们购买那些易于安装的太阳能灯。故选A项

5.C

考查对上下文的理解和推理判断能力。由该空前的“Different solar lights can store different amounts of energy”可知，不同的太阳能灯点亮的时间长短也不相同，故C项说法符合些语境。
