【原文5】 For the next day and a half, when it was obvious that Israel had no intention of complying, Mrs. Kirkpatrick said, Israelis could not be obliged to withdraw, if the Palestinian forces and Syrians were not withdraw as well.

【分析】本句在原文中when从句是前置的，而且与主句在内容上是连贯下来的，汉语译文中便也保留了两个分句原来的位置，用“已经……，这时……便……”把它们连贯起来。

【原文6】Why learn to play the piano, when you can listen to the world's greatest pianists in your own drawing-room?

【译文】当你能在客厅里欣赏到世界上最出色的钢琴家的演奏时，你干吗要学钢琴呢？
