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.

英語四級譯文:
1997年，威爾士王妃戴安娜出訪安哥拉，支持紅十字會關于全面廢除非人道地雷的活動，這一事件在當時引起了轟動。

四級詞匯講解:
when引導的是主語從句，句首的it僅為形式主語。插入語Princess of Wales是Diana的同位語;to support the Red Cross's campaign...landmines為目的狀語，其中all anti-personnel landmines為介詞on的賓語。

campaign for的意思是“要求(為爭取)…的運動”。如:
He conducted a compaign for reform.他領導了一場要求改革的運動。

ban on的意思是“對……的禁令”。如:
There is a total ban on smoking in the office.辦公室全面禁止吸煙。
