290. It came as something of a surprise when Diana, Princess of Wales, made a trip to Angola in 1997, to support the Red Cross's campaign for a total ban on all anti-personnel landmines.
译文1997年，威尔士王妃戴安娜出访安哥拉，支持红十字会关于全面废除非人道地雷的活动，这一事件在当时引起了轰动。
点睛when引导的是主语从句，句首的it仅为形式主语。插入语Princess of Wales是Diana的同位语；to support the Red Cross's campaign...landmines为目的状语，其中all anti-personnel landmines为介词on的宾语。
campaign for的意思是“要求（为争取）……的运动”。如：
He conducted a compaign for reform. 他领导了一场要求改革的运动。
ban on的意思是“对……的禁令”。如：
There is a total ban on smoking in the office. 办公室全面禁止吸烟。
考点归纳有关surprise的短语有：
come as a surprise意为“出乎意料”。如：
