例28　Some companies are limiting the risk by conducting online transactions only with established business partners who are given access to the company's private internet.

【结构分析】主语中心语是Some companies，谓语动词是limit，宾语中心语是the risk, by conducting online transactions做状语修饰主干，with established business partners修饰online transactions, who引导的定语从句，修饰established business partners。

【亮点回放】这句话难在介词短语修饰谁，以及主干的确认，这句话的亮点在于很多介词短语连环使用，层层相套，后面还有一个简约而不简单的定语从句，很押韵。

【核心词汇】

limiting the risk　降低风险

conducting online transactions　开展网络交易

established business partners　老顾客

given access to　准许进入

【参考译文】很多公司通过只与那些被允许进入到公司私人网站的老顾客开展网络上的交易来降低风险。
