句子1
Over the past century, the composition of the human gene pool has not changed appreciably, but with increasing global partici//www.58yuanyou.compation in athletics and greater rewards to tempt athletes，it is more likely that individuals possessing the unique complement of genes for athletic performance can be identified early.
译文：
在过去的一个世纪里，人类基因库的成分并没有显著的变化，只是全世界有越来越多的人参与运动，诱惑运动员提高成绩的物质奖励也越来越多，因此现在比以前更有可能尽早发现那些独具运动基因的个体。
分析：
本句的基本句子结构是：..., but ... 表达的是一个转折。但在but之后的转折中，句子呈现出较为复杂的结构，即with..., it is more likely that...，理解这个句子的关键就在于如何理解with引导的短语。这里，with后面跟了两个并列词组：increasing globla participation in athletics(全球范围内越来越多的人参加运动）及greater rewards to tempt athletes（越来越多的奖励来刺激运动员）。可以看出，这里with引导的内容解释了后面的it is more likely that...，也就是说，这里with 引导的是两个原因。
阅读练习-判断正误（True, False, or Not Given)：
The growing international importance of athletics means that gifted athletes can be recognise//www.58yuanyou.comd at a younger age.
[参考答案] T。The growing international importance of athletics正好总结了原文中with引导的两个内容。
句子2
And today the task of reproducing pictures is incomparably morwww.58yuanyou.come simple and reliable, with reprographic techniques that allow the production of high-quality prints made exactly to the original scale, with faithful colour values, and even with duplication of the surface relief of the painting.
译文：
如今，复制图片变得简单而且可信多了，复印技术使得高质量的印刷产品与原尺寸相同，还有高保真的色彩，甚至图片表面的凹凸起伏也能复制。
分析：
这个句子的基本结构是：...the task ... is more simple and reliable, with..., with..., and with... 。这里，主句表达的是一个整体概念，后面用三个with qeeunVr引导的名词短语来补充细节。
阅读练习- 填空:
...these days new methods of reproduction allow excellent replication of surface relief features as well as colour and _______.
[参考答案]scale 。原文with引导了三个细节，即scale, color, and relief features，填空处缺失的正好是scale。
