Unit 1 Nothing ventured, nothing gained课文长句难句剖析1. The smell is, as usual, almost unbearable, being a mixture of sweat, seal oil fat, and dirty underwear.剖析：being a mixture of sweat, seal oil fat, and dirty underwear 是现在分词短语，作表语 unbearable 的补语，进一步解释 unbearable 的原因。译文：气味像平时一样几乎让人无法忍受,有汗味、海豹油味，还有肮脏内衣的气味。2. I try to think of happier things: warm and dry clothes, a cosy bedroom, sunny days, my mother’s face and the celebration we will get when we return, for I am part of a failed expedition that tried to cross the continent of Antarctica, something that had never been done before.剖析：try to 的意思是：努力去做。。。。。。／试图想要。。。。。。（但往往没有做成功） 比如：Jack tried to stand up on the head but (he) failed.杰克想用头着地倒立，可是没有立起来。think of 是“想起、想到、认为”等意思。比如：She felt afraid when she thought of the story his boy friend told her the other day.她一想起男朋友那天给她讲的故事就感到害怕。 3. … for I am part of a failed expedition that tried to cross the continent of Antarctica, something that had never been done before.for 引导的“顺便表示原因的”状语从句。比如：Tom didn’t come today for he is ill.汤姆今天没来，因为他生病了。Because 是用来回答 why 提出的问题的，语气最强；since 引导原因状语从句时，含有“前提条件、前提原因”的意思。比如：——Why didn’t you come to my birthday party last weekend? 你为什么不来参加我上一个周末的生日聚会？ ——Because I was away on business in Shanghai. 因为我出差在上海呢。Since this method doesn’t work, let’s try another.既然这个方法不行，我们试用另一种吧。在这个状语从句里包含两个 that 引导的定语从句，分别修饰 expedition 和 something，something 指 to cross the continent of Antarctica 这一件事。 注意：“。。。中的一员”英语要说成：… ...
