【话题解读】本文主要介绍了一种自己可以亲手制作的简单易行的太阳能蒸馏器的方法，并介绍了它的工作原理。

这种蒸馏器所需的材料简单，适用于任何缺水的地方。

32.D【解析】推理判断题。

根据第一段最后一句话Thesepiecescanbefoldedintoaneatlittlepackandfastenedonyourbelt.可知制作蒸馏器的东西可以叠放在一个小包里，系在腰间，这说明制作蒸馏器的设备很轻便，portable表示“轻便的；手提的”，故选D。

杯子的工作效率是不变的。

故选B。

34.C【解析】细节理解题。

根据第三段Next,covertheholewiththeplasticsheet,securingtheedgesoftheplasticwithdirtandweightingthesheet’scenterdownwitharock.可知最后一步是weightingthesheet’scenterdownwitharock（放一块石头在覆盖膜的中间，把它压下去），故选C。

35.D【解析】推理判断题。

结合第四段中的Groundwaterevaporates（蒸发）andcollectsonthesheetuntilsmalldropsofwaterform,rundownthematerialandfalloffintothecup可知地下水蒸发，在覆盖膜上聚集起来，直到形成小水滴落在杯子里，覆盖膜是在杯子上面的，水滴落入杯子里，所以水滴是凝聚在覆盖膜的下面。

故选D。
