1.Traditionally, pollination by wind has been viewed as a reproductive process marked by random events in which the vagaries of the wind are compensated for by the generation of vast quantities of pollen, so that the ultimate production of new seeds is assured at the expense of producing much more pollen than is actually used. (4)
传统上，风媒传粉被看成是这样的繁殖过程：其特征就是由一些随即事件的发生，在这些随机事件里，风的反复无常被大量的产生花粉所补偿，以至于新种子的最终产生被保证了，其代价是产生远远多于实际使用量的花粉。
难句类型：复杂修饰
解释：笔者曾经遇到过一个同学，下课以后来找我，说这篇文章读得不好，因为首段的两句话看不懂。这篇文章的首段很长，但仅由两句话构成，不但讲述了老观点的内容，而且解释了这篇文章的主题的所在，从这里我们可以看出在现场迅速读懂难句的重要性。Marked by之后的内容修饰reproductive process的。其后的random events后面又跟着一个定语从句来修饰它。从句中的被动语态the vagaries of the wind are compensated for by the generation of vast quantities of pollen有些特殊，因为文中不是按照中文的习惯说are compensated，而是说compensated for，这是由于主语the vagaries of the wind并不是被补偿的对象，而是补偿的对象，后面的at the expense of是以…为代价的意思。
意群训练：Traditionally, pollination by wind has been viewed as a reproductive process marked by random events in which the vagaries of the wind are compensated for by the generation of vast quantities of pollen, so that the ultimate production of new seeds is assured at the expense of producing much more pollen than is actually used.
