阅读理解 I used to work in an office,which had a locust tree growing outside the window. It had grown into a tall tree and must have been there for a long time. The tree blocked the view and made the office seem dull. Unfortunately,this happened to be the room assigned(分配)to me,and I was depressed by it for quite some time. When the first spring came,everything was green except the locust tree. I felt very happy because I had thought it had died! One morning,when I opened the window for some fresh air,I unexpectedly smelt a familiar sweet scent floating into my office which I could not name. Suddenly,I realized it was the locust tree!The treethat I thought dead was in full bloom! From then on,I usually came to the office very early to see dew(露珠)forming on the locust tree blossoms,and was eager to see spring again every year. During summer,the green leaves provided shade protecting me from the harsh sunlight,but allowingenough light in to make it pleasant. In autumn,the leaves turned many different colors. Its beauty touched my soul. Many times,I thought to take photos but never did. Then,I had to leave in a hurry. Later in life,it became a great regret that I had not done so. Actually,many times in our lives,we think we own something and thus do not value it. We don't feel regretful until we lose it one day!Moreover,sometimes,we have to accept the things we don't want and need to discover the hidden beauty to find unexpected joy!1.
