英语句子语法分析

Nowadays many business meetings take place outside the office, which makes entertaining clients and customers become an increasingly impotant part of business.---这是一个由which引导的非限定性定语从句，which指代前面的整个句子

There are so many companies clients can choose to do business with，so it is important to differentiate yourself by building confidence and trust.
前面是个there be句型 后面是个由so引导的结果状语从句
so后面的是强调句型 it is +adj +to do sth it是形式主语，真正的主语是后面由不定式引导的短语

With more sporting venues to choose from than ever， it can be easily found there is something for every client, whether it's golf,baseball,tennis or auto racing.
句首是个with 的复合结构--with+n+to do 这里表伴随
it can be easily found there is .... 这里found后面是个省略了that的宾语从句 因为there is这个从句没有缺少任何成份，that 省略。
whether it's golf,baseball,tennis or auto racing 这是由whether 引导的非限定性定语从句，先行词是something。我们学过，先行词是不定代词时必须由that引导定语从句，但这里是非限定性定语从句，而且是不确定指代，所以用whether

The time away from the office allows the company to get to know the client more personally without office interruptions and sporting events offer a very social atmosphere in which to do business.
句子有点长，其实分析下来很简单。
away from the office 后置定语修饰前面的the time
without office interruptions and sporting events offer a very social atmosphere in which to do business. 是一个介宾短语作状语
in which to do business 这是一个由介词+which引导的定语从句，先行词是atmosphere 相当于where引导的定语从句子 可改成：a very social atmosphere where can be used to do business

在给学生分析句子的结构时一定要想办法让学生自己找出句子的主干，中国的孩子在学英语时没办法找到句子的主干，这是我们在上课时一定要反复强调的。

Nowadays many business meetings take place outside the office, （which makes entertaining clients and customers become an increasingly impotant part of business. ）---定语从句，which指代前面的整个句子

There are so many companies（ clients can choose to do business with）----定从句，省略了which, （so it is important to differentiate yourself by building confidence and trust.）-----句型it is +adj=to do sth

With more sporting venues to choose from than ever,-----(with 的复合结构--with+n+to do), it can be easily found there is something for every client, whether it's golf,baseball,tennis or auto racing. ---（there be句型）

The time （away from the office allows the company to get to know the client more personally without office interruptions and sporting events）----定语从句 offer a very social atmosphere （in which to do business. ）---定语从句

应该还算清楚了，楼主看我，看我，哈哈哈
