主题：大家来帮忙~~

我也是。。。不懂语法。。来看看。。

呵呵，或者~~~碰到有问题的句子，抓起一阵猛读，读到大脑眩晕，觉得＂哎挺顺口的呀~＂，就行了~~...

By the way，我觉得it指"be a big boost to (the given city)"的状态，就像形式主语一样，所以没问题（我一直觉得it是O型血～～～呵呵 ）

是啊，我觉得23楼说的对，it是指申奥成功带动经济大涨的情况，不仅仅是指boost。

Beijing's success, economically, will be as big a boost to Beijing as it was in the run up to the Games in Tokyo in 1964, and Seoul in 1988.
可以说这是非常书面的英语,除了and前面的逗号值得商讨外,and前加逗号时后面为从句,当然这里也可讲成承前省略"it was in the run up to the Games in".
另外,英语跟中文也有相通的地方,就是不必事事表达完整,可以根据场景而有所省略,比如说我们正做某事,但还没做完,就有人来催了,来催的人会说:"快点,怎么还没做完?",当然啰嗦点的人会说:"你搞快些,就这么点事怎么还没弄好?"想当年我们申奥成功了,北京在干什么是众所周知的,整篇文章所讲的都是申奥,所以只说"北京的成功",而不用讲"北京申奥的成功".
另讲一下as(so)...as,与...一样:中间用形容词,形容 词要修饰的词放在其后.例如,He is As brilliant a politician As ever lived. I am as good a student as I can.

Beijing's success, economically, will be as big a boost to Beijing as it was in the run up to the Games in Tokyo in 1964, and Seoul in 1988.

it 应该指申奥成功带来的经济飞跃,即boost , 而run up 我觉得应为run-up理解为经济的迅猛增长(或上升), 主句应该就是Beijing's success,will be as big a boost to Beijing 后面的as引导的,只是用来修饰boost的,可以理解为定语从句

我的语法也不好，凭感觉，觉得这位MM的句子比较合适~

Beijing's successful Olympic bid, from an economic point of view, would be a great promotion, as the 1964 Tokyo Olympics and the 1988 Seoul Olympics brought about by economic growth.

Beijing's success, economically, will be as big a boost to Beijing as it was in the run up to the Games in Tokyo in 1964, and Seoul in 1988.首先，boost 是一个动词，不是名词，改为promotion；然后，这里的it不能是big，而应该是promotion。最后，and Seoul in 1988, 和前面的那个Tokyo in 1964是并列的，略去逗号。修改的话，改为：
Beijing's success， economically, will be a promotion to Beijing, as big as it was in the run up to the Games in Tokyo in 1964 and Seoul in 1988.

in the run up to 为固定搭配，原文并无问题。由于后面有年份且是说话双方都明知的内容，所以后面简为the Games

另外as big a boost 是在一起用的，不要拆开来理解

读着也读得通，但总觉得有些别扭as it was in the run up to the Games
