Years ago, I lived in an apartment in a large city. The house next door was only a few meters away from 1.(my). Through the window, I could often see a woman reading in the house every afternoon.

Several 2.(month) went by, I began to notice that her window was dirty. Everything was not very clear through the dirty window. I wondered 3. the woman didn't wash her window. It 4.(real) looked terrible.

One bright morning, I decided 5.(clean) my house, including washing the window inside. Late in the afternoon when I 6.(finish) all the cleaning, I sat down by the window with a cup of coffee. 7. surprising! I found that the woman's window was so clean 8. she could be seen clearly sitting by the window.

That was quite an important lesson for me. How often had I looked at others through my 9. shortcomings(缺点)?

Since then, I have always been thinking more 10. before and trying to clean the dirty window, in this way, I may see the world around me more clearly.
