After I moped around for a few weeks, my friends gave me a surprise party for my B-day.

闷闷不乐地过了几个星期后，我的朋友出奇不意地为我举行了一个生日晚会。

I moped around from room to room, gathering souvenirs and throwing out the garbage he never had the chance to.

我拿抹布一间间地清理着房间，收集起来所有的纪念品，并把他以前从没有机会扔掉的垃圾清理出去。

I would advise against riding moped without testing the brakes first.

我反对不先试一下闸就骑机动脚踏两用车。
