长难句分析：动物生存能力
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; 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. (TPO 1 Groundwater)
托福阅读长难句句子分析 本句由but引起了前后两个分句，其中都有if引导的条件状语从句，表示两种假设的情况。读懂这种复合句的关键是要迅速找到并理解其主句的谓语部分。本句主句的谓语部分有will exist , will drain away和will exist , will be firmly held。此外，两个分句里都有大家所熟悉的too...to...结构，这里都作后置定语，起修饰作用，意思是“太……以至于不能……”。
词汇精记 ? pores指的是“孔隙”，这里说的是“岩石的孔隙”。
? surface tension指的是“表面张力”。
? film在这里显然不是“电影”，表示“薄膜”，比如：a film of oil on the surface of the water 水面上的一层油。另外，film还有“胶卷”的意思，比如：develop a film 冲洗胶卷。注意film还可以作动词，表示“拍摄”，比如：The explosion had been filmed by an amateur cameraman. 这次爆炸被一位业余摄影师拍摄了下来。
托福阅读长难句参考译文 如果岩石的孔隙很大，其中的水会形成水滴，而这样的水滴太重而足以克服吸引它的表面张力，就会流走；但是如果岩石孔隙足够小，其中的水会形成薄膜，因为太轻而无法克服吸引它的表面张力，从而会牢牢地附着在孔隙表面上。
If it were not for this faculty, they would devour all the food available in short time and would probably starve themselves out of existence.
(虚拟语气)
【译句】如果不是具有这种能力，它们就会在短时间内吞掉所有能得到的食物，而且很可能会因饿死而灭绝。
分句1. If it were not for this faculty
分句2. they would devour all the food available in short time
分句3. would probably starve themselves out of existence
分句1 是虚拟语气的条件从句
分句2、3是并列关系，并且是主句。
The fact that half of the known species are thought to inhabit the world's rain forests does not seem surprising，considering the huge numbers of insects that comprise the bulk of the species.
(同位语从句fact that…;定语从句that comprise the bulk…)
【译句】考虑到组成大部分物种的昆虫的巨大数量，认为半数的已知物种栖息在世界的雨林中这一事实看起来并不令人吃惊。
分句1：The fact does not seem surprising.
分句2：that half of the known species are thought to inhabit the world's rain forests
分句3：considering the huge numbers of insects
分句4：that comprise the bulk of the species
分句1中嵌套着分句2，分句2解释说明分句1的主语the fact, 是同位语从句；分句3是主句的状语，分句4是定语从句，修饰分句3的the huge numbers of insects
