本文是一篇记叙文。

就在他很孤独无助的时候，一位陌生人打电话来告诉他，他们的女儿捡到了他的文件。

丈夫的东西最后失而复得，令作者一家很欣喜，这同时也让他们重拾对人们的信任。

D.InSearchofNewFriends.

本题考查考生理解全文、提炼信息、概括总结的能力。

本文主要记叙了作者的丈夫来到悉尼之后，有一天发现自己的手提箱丢失了，里面有自己的像护照这样的全部重要文件。

正当作者的丈夫一筹莫展的时候，一位当地的陌生人给他打来电话，告诉他说他们的女儿在垃圾桶里捡到了这些文件，这些本来可能被当作垃圾扔掉的文件最后却回到了失主手中，这让作者一家很欣喜，同时也让他们重拾对人们的信任等，所以这些都是宝贵的财富，因此选TurningTrashtoTreasure，这正是本文的主题所在。
