Research says more and more business training and business meeting taking place online. 

Do the advantages outweigh the disadvantages?

在应对这道题时，考生在主体部分写了如下一句

The reason behind this is that getting to the given locations, people need to pay for the traffic fees and spend the extra time, even some external problems may impede their way to business working.

☆ 考生在写这句话的时候，考虑到出行的时间费用成本，顺便还会“脑补”一下出行过程中的突发情况。然而，这恐怕就有点扯远了，何况看过多期“7分句”专栏的大家能一眼识别的external problems这个复数概念抽象名词并未细化解释吧？

☆getting to the given locations 考生本意是用现在分词短语作目的状语，行不通呢，表目的时我们一般使用to do。

改写如下：

The main reasons for this are that people do not need to spend either their time or their money on travelling to the location where the training or meeting is taking place.

☆ 虽然that …部分只是一个从句，但语义上传递的信息是“既不用费钱又不用费时间”，可以理解为两个因素，因此用the main reasons are that …

☆ either … or … 可以用于否定句，表示该否定两个选项（You use "either" in a negative statement in front of the first of two alternatives to indicate that the negative statement refers to both the alternatives.）

例句1：They found no signs of either him or his son.

例句2：… music that fails to be either funny or funky.
