Once I suddenly found my longtime 【3】 (use) umbrella “disappeared”． I really got lost and regretted quite some time 【4】 my own carelessness．

Several days later, out of my 【5】 (expect), I saw it quietly stand in a corner of the house where I worked． I was extremely glad to regain it． Looking carefully at it, though it was so familiar 【6】 me, I found for the first time its wooden handle 【7】 （wear）out as a result of repeated rain-wash for years． I sought for it only when I needed it． It occurred to me that I should have paid 【8】 (much) attention to it．
