晓松在参观一个容积为5×10³m³ 粮仓时，想知道这粮仓能装多少质量的稻谷，于是他取一小包稻谷作样品，进行了以下实验：
（1）调节天平平衡时，发现天平的指针偏向分度标尺的右侧，此时，应将平衡螺母向____ （填“左”或“右”）调，直至天平平衡。
（2）取适量稻谷倒入左盘，在右盘中加减砝码，并移动称量标尺上的____ ，使天平重新平衡，所用的砝码和游码的位置如图所示，则稻谷质量为____ g，将这些稻谷倒入量筒中压实，测出它的体积为40 cm³。
（3）稻谷的密度为____ g/cm³，这个粮仓大约能装____ kg的稻谷。

    As a boy I was always small for my age. I was five years younger than one of my brothers and seven years younger than the other. 1, I often felt left out when their friends came over to 2. I was too 3for whatever they were doing and they didn't want me to listen to their conversations either. More often than not I found myself outside playing  4and feeling forgotten.

    I remember one Spring afternoon I felt especially 5as I sat in the yard behind our house. We lived miles from town and I 6saw my own friends outside of school. I 7my brothers laughing from 8the house and felt a single tear coming down my face. At that moment I saw a large brown dog 9me. He was wagging (摇摆) his tail 10. He greeted me like a long lost11, licking (舔) my hand and sitting beside me on the grass,12he didn't know me. I petted and13this four-legged angel (天使). He let me pour out all my troubles and14my deepest thoughts before he kissed me goodbye. I went back inside feeling happy,15that no matter what life might hold I was loved. I16that the dog was sent in that moment of17to remind me just how much I was loved.

    In truth, nothing brings us greater18than knowing we are loved. Knowing we are loved gives us the19to love others as well. It also helps us to be the people the world meant for us to be. Remember how much the world loves you and share your20with the world.
