in seventh heaven: 异常幸福

这个习惯用语用了有两百来年了。它的出典可能是犹太人或者穆斯林的古老信仰，说是天堂分为七层，而至高无上、尽善尽美的就是那第七层，惟有上帝和身居高位的天使才能住在七重天上美伦美奂的天宫里。

例句：Mary and Bob are still in seventh heaven a year after their wedding. They were sweethearts all through college and never looked at anyone else -- they're the happiest people I know.

玛丽和鲍勃在结婚一年后的今天仍然极其幸福美满。整个大学时代他们就心心相映。他俩在我认识的所有人中是最幸福的一对。
