众所周知，考研英语的一大难点就是长难句。今天继续带领大家一起分析两个句子。
This trend, which we believe is still in its infancy, effectively began with retailers and travel providers such as airlines and hotels and will no doubt go further.
结构分析：本句主句是并列结构，this trend began with，之后以and连接，will will no doubt go further。句子前面是非限定性定语从句，还原后是we believe this trend is still in its infancy.
译文：我们相信这种趋势现在仍在起始阶段。这种趋势以零售商和诸如航空公司、旅馆等旅行服务提供商为开始，快速发展，而且毫无疑问会进一步发展。
The same dramatic technological changes that have provided marketers with more (and more diverse) communications choices have also increased the risk that passionate consumers will voice their opinions in quicker, more visible, and much more damaging ways.
结构分析：该句主句是technological changes increased the risk。changes后的that have provided marketers... 是定语从句，先行词changes作主语。risk后面that passionate consumers...是同位语从句，具体说明risk是什么风险。
译文：同样的剧烈技术变革一方面给营销商提供更多（以及更多样化的）传播渠道，另一方面也增加了风险，反应激烈的顾客发表观点更迅速，这些观点更容易引人注意，也更具有破坏性。
