On our way home that night I looked down and saw that the necklace was not around my neck any more. I told Pierre. We rushed back to the palace and looked for it.We asked everyone there if they had found a necklace, but without luck. We couldn't find it;

那天晚上在回家的路上，我低头一看，发现项链不再挂在我的脖子上了。我告诉了比尔。我们马上赶回王宫去寻找。我们询问了那儿的每一个人，问他们是不是拾到了一条项链。可是，真倒霉。我们找不到那条项链；它丢失了。
