题目:
If the pores arelarge, the water in them will exist as drops too heavy for surfacetension to hold, and it will drain away; but if the pores are smallenough, the water in them will exist as thin films, too light toovercome the force of surface tension holding them in place; then thewater will be firmly held.
解析：
找出本句的逻辑关键词，是分号后面的but。那么，这就话是一个转折关系。
If the pores are large, the water in them will exist as drops too heavy for surface tension to hold, and it will drain away;这部分意思是：如果孔很大，那么空中的水就会以水滴的形式出现，这个水滴太重了以至于石头的表面张力不能够承载住他，那么水滴就会流走。but if the pores are small enough, the water in them will exist as thin films, too light to overcome the force of surface tension holding them in place; then the water will be firmly held.这部分的意思是：但是如果水滴足够小，那么石头中的水滴会以薄膜的形式出现，这个薄膜很轻从而不能突破石头的表面张力；所以水滴就被紧紧的存在石头中。
这句话其实是在对比什么样的水滴能够存在石头中。
