The Trees Outside My Window
Read the article quickly and answer the following questions.
1. Why did the author regard the hibiscus tree as her best friend？
2. Why did the author feel surprised when she saw the blossom plum tree？
From the window of my room， I could see a tall cotton-rose hibiscus. In spring， when green foliage was half hidden by mist， the tree looked very enchanting dotted with red blossom. This inspiring neighbor of mine often set my mind working. I gradually regarded it as my best friend.
Nevertheless， when I opened the window one morning， to my amazement， the tree was almost bare beyond recognition as a result of the storm ravages the night before.Struck by the plight， I was seized with a sudden saddens at the thought “all the blossom is doomed to fall”. I could not help sighing with emotion： the course of life never runs smooth， for there are so many ups and downs， twists and turns. The vicissitudes of my life saw my beloved friends parting one after another. Isn’t it similar to the tree shedding its flowers in the wind？
This event faded from my memory as time went by. One day after I came home from the countryside， I found the room stuffy and casually opened the window.Something outside caught my eye and dazzled me. It was a plum tree all scarlet with blossom set off beautifully by the sunset. The surprise discovery overwhelmed me with pleasure. I wondered why I had no idea of someunyielding life sprouting over the fallen petals when I was grieving for the hibiscus.
