　　4.When a solar still works,drops of water come into the cup from　　　.

　　A.the plastic tube B.outside the hole

　　C.the open air D.beneath the sheet

　　答案　D

　　解析　推理判断题。从文章最后一段的“Ground water evaporates and collects on the sheet until small drops of water form,run down the material and fall off into the cup.”可知,这种蒸馏器的工作原理是创造一个温室。地面的水向上蒸发并在塑料布上聚集形成小水滴,然后水滴顺着塑料布流下来落到杯子里。

　　【长难句分析】When the container is full,you can suck the refreshment out through the tube,and won’t have to break down the still every time you need a drink.

　　当容器满了的时候,你就可以通过管子把水吸出来,而不必每次喝水的时候都把蒸馏器拆开。

　　本句是个复合句。when引导的是时间状语从句,and连接的是两个并列句,every time是名词性短语作连词,引导时间状语从句。
