题目

对需测量的科学量进行估测，是一种良好的学习习惯，也是学好科学的基本功之一。下面是小宇同学对自己身体相关物理量的估测，明显不合理的是（） A . 体重大约有50Kg B . 手指甲的宽度约为1mm C . 体温大约为37℃ D . 身体的体积大约是50dm3 答案：BMy mother loves flowers. As soon as warm weather comes around，you will find her planting，watering and weeding over everything. For many years we lived next door to each other，and she spent as much time in my garden as she did her own. After the flowers became plentiful each summer，she would cut colorful bouquets(花束)to enjoy inside the house－both hers and mine. I would often come home from work and find a beautiful arrangement of fresh flowers on my coffee table. Shortly before Christmas one year，a local flower shop offered a bouquet a month special. It seemed to be a great way to thank her for all of the flowers she had given me through the years. After the holidays，in early January，I drove her to the flower shop to pick up her first month’s bouquet. The small fresh colorful bouquet would hardly fill a small vase. I was so embarrassed(尴尬的).However，after we returned home，she began to arrange the flowers she had received. “Mom，I’m sorry，”I told her. “I can’t believe how skimpy that bouquet is.” She looked at me and smiled. “It’s okay，”she said. “It allows me to better enjoy the beauty of each one.” Mom’s words helped me to realize something bigger and more important－when we have too many good things，we often fail to enjoy the beauty of each one. Thanks，Mom，for helping me understand that less is sometimes more. 58．According to Paragraph 1，which of the following is TRUE? A．The author’s mother usually bought flowers for her daughter.
