题型：单项选择题 阅读理解。 Years ago,I lived in a building in a large city. The building next door was only a few feet away from mine. There was a woman who lived there and whom I had never met, yet I could see her sitting by her window each afternoon, sewing (缝纫) and reading. After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, "Why doesn't that woman clean her window? It really looks terrible." One bright morning I decided to clean my flat,including cleaning the window. Late in the afternoon after I finished the cleaning, I sat down by the window with a cup of coffee fora rest. What a surprise! The woman sitting by her window was clearly seen. Her window was clean! Then it dawned on me. I had been criticizing (批评) her dirty window,but all the time I was watching hers through my own dirty window. That was quite an important lesson for me. How often had I looked at and criticized others throughthe dirty window of my heart, through my own shortcomings (缺点)? From then on, whenever I want to judge someone, I ask myself first, "Am I looking at him through my own dirty window?"
