如图所示，超凡同学为探究物体所受浮力大小跟物体排开液体体积关系，将一金属圆柱体挂在弹簧测力计下缓缓浸入水中（水足够深），在金属圆柱体接触容器底 之前分别记下圆柱体下表面到水面距离h和弹簧测力计相应的示数F ，实验数据如下表：
(1) 分析表中数据，可以得出金属块重___________ N ，完全浸没时，金属块受到的浮力为__________N ；
(2) 分析第1 次到第4 次实验数据，说明了浸在液体中的物体，所受浮力大小与物体排开液体的体积__________；（选填“有关”或“无关”）
(3) 分析第5 次到第7 次实验数据，说明浸没在液体中的物体受到浮力大小与深度__________ ； （选填“有关”或“无关”）
(4) 下图中能正确反映浮力F 浮和物体下表面到水面距离h 关系的图象是_________
(1)6.5；2
(2)有关
(3)无关
(4)D
Mrs. Barrow, room 501, I repeated to myself as I was looking for the room number. It was my first day of grade and I was really . Stepping into the room, I felt . I tried to keep calm, but Mrs. Barrow saw through me. “Good morning, Courtni. You may pick your .” I glanced round the room and took a(n) seat near a girl named Wendy. Soon, Wendy and I became good friends. I felt no closeness to Mrs. Barrow, . Mrs. Barrow had us write a paper what we wanted to be when we grew up. She said that when her students graduated, she liked them to come back and their fifth-grade dreams together, as a memory of their childhood. I decided right then that I liked Mrs. Barrow. A month later, my grandmother died of cancer. her was so painful for me that I __ some school. At the funeral(葬礼), I was sitting feeling sorry for myself when I looked and saw Mrs. Barrow standing there. She my hand and comforted me by reminding me that Grandma had no more pain or . had never occurred to me that it was better for my grandma this way. After the funeral, we went home to see the flowers that had been sent. My mom me a pretty ivy(常春藤) plant. The attached card : Courtni, I’m sorry about your grandma. Never forget, I love you. With love, Mrs. Barrow I wanted to . I took the plant home, watered it and put it in my grandma’s old room. I am in eighth grade now and I have that plant. I never thought a teacher could that much about her students: now I know.
