⼤学英语六级考试阅读长难句100句解析（⼀）1. Wearing a seat belt saves lives; it reduces your chance of death or serious injury by more than half.2. But it will be the driver’s responsibility to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind.3. However, you do not have to wear a seat belt if you are reversing your vehicle; or you are making a local delivery or collection using a special vehicle; or if you have a valid medical certificate which excuses you from wearing it.4. Remember you may be taken to court for not doing so, and you may be fined if you cannot prove to the court that you have been excused from wearing it.5. Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the process of ageing could he slowed down.6. With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations.7. Computer technology enabled the researchers to obtain precise measurements of the volume of the front and side sections of the brain, which relate to intellect (智能) and emotion, and determine the human character.8. Contraction of front and side parts as cells die off was observed in some subjects in their thirties, but it was still not evident in some sixty and seventy-year-olds.9. The findings show in general terms that contraction of the brain begins sooner in people in the country than in the towns.10. White collar workers doing routine work in government offices are, however, as likely to have shrinking brains as the farm worker, bus driver and shop assistant.译⽂：1、系好安全带能够挽救性命，它能将丧⽣和重伤的概率减少⼀半以上。

(2009年6月)【分析】本句为复合句，主架为… turtles have struggled…。

【析句】本例句的难点在于寻找主句的'主干。
很明显，主句由but连接两个并列句组成，but后的句子that is nonetheless the case 是简单句。
but前的句子主句是the notion would seem merely silly to the greater part of the academic establishment，to在这里作介词，这一介宾结构提前放在了谓语动词seem后，容易让人误以为是短语seem to的用法，结果导致理解失误。
最后主句主语the notion 有that引导的定语从句修饰。
2. Already the public agencies for adult education are swamped by the tide that has swept over them since depression began.【译文】从事成人教育的公共机构已经因为经济萧条开始以来席卷全国的趋势而陷入困境。

1. She recalls watching the ship, brightly lit, slipping into its dark grave - and into seeming nothingness, rarely mentioned for more than half a century.【译文】她回忆起看着轮船被火光照亮，慢慢沉入漆黑的墓穴，最后永远消失。
这场悲剧半个世纪以来极少被提起。

they are in danger… help作meaning的宾语，相当于省略了引导词that的宾语从句。
【译文】这些数字迫使Oceana向政府请求将对北大西洋大海龟的保护程度由“受到威胁”提升到“濒临灭绝”，这意味着如果没有额外的保护，它们将面临消失的危险。
3.But Nature is indifferent to human notions of fairness, and a report by the Fish and Wildlife Service showed a worrisome drop in the populations of several species of North Atlantic sea turtles, notably loggerheads, which can grow to as much as 400 pounds.

about to go into debt为families的后置定语，to fund four years为不定式作目的状语，of partying, as well as studying为介词短语作后置定语。
that college… investment为同位语从句，作knowledge的同位语；that… should yield huge dividends为定语从句，修饰的是investment，在该从句中，unlike many bankstocks为插入语。
