在英语写作中，长短句的灵活运用可以增强文章的表达效果。长句可以使文章更详细、复杂，而短句可以使文章更简洁明了，突出重点。合理运用长短句结合的方式，可以使文章更生动、有力，更易于理解。
长句可以包含更多的信息，使文章更为详细、复杂。但是如果全篇都是长句，读者容易感到疲惫。短句则可以使文章更加简洁明了，突出重点，增强语言的表现力。因此，合理运用长短句结合的方式，可以使文章更加生动、有力。
例如，以下是一段较为单调的长句：
The fact that the company had failed to meet its sales target due to poor market conditions, which in turn led to a decline in revenue and profitability, was a cause for concern and required immediate action to be taken in order to rectify the situation.
与下面这段结合了长短句的表达方式相比：
The company's failure to meet its sales target was due to poor market conditions. As a result, there has been a decline in revenue and profitability. This situation is a cause for concern and requires immediate action to be taken in order to rectify it.
两者相比，后者更加易于理解，更加生动有力。
