     When I was twelve years old, my family were the first black people to move into an all white part of
Grand Rapids, Michigan. Many of our new neighbors weren't very welcoming. Some of them said angrily
that we should return to where we came from. The children sometimes threw stones at me or drove me
home from school.
     Most of my teachers simply took no notice of me, but not Dorothy Bean, my history teacher. Miss Bean
was angry at how badly I was being treated, but she didn't say this to me. Miss Bean showed her respect
for me by teaching me just like anyone else. Instead of being unnoticed, I was given a chance to show that
I was clever. Miss Bean was the first teacher who ever made me think for myself. She always wanted to
know what I thought about difficult questions. Was Thomas Jefferson right to buy Louisiana from France?
Why? She expected me to have my own idea. Miss Bean was teaching me that thinking for oneself was the
real key to education.
     One day, when I was not paying attention in class, Miss Bean suddenly threw an eraser at me. The eraser
hit me right on the hand and sent my pencil flying. The whole class were very surprised at first, then started
laughing. This event became famous in the school and, because it happened to me, the students wanted to
get to know me. So that's the story of how Dorothy Bean made me her target (靶子), and how I became
just another kid in school.

(10分)某生物兴趣小组为研究某植物生长发育过程中植物激素间的共同作用,进行了相关实验。
(1)下图为去掉其顶芽前后,侧芽部位生长素和细胞分裂素的浓度变化及侧芽长度变化坐标曲线图,据图分析:

①激素甲代表的是              。
②高浓度的生长素和细胞分裂素对侧芽萌动分别起的作用是         
(2)为研究根的向地生长与生长素和乙烯的关系,该兴趣小组又做了这样的实验:将该植物的根尖放在含不同浓度的生长素的培养液中,并加入少量蔗糖做能源。发现在这些培养液中出现了乙烯,且生长素浓度越高,乙烯的浓度也越高,根尖生长所受的抑制也越强。
①该实验的因变量是          
②为使实验严谨,还需要另设对照组,对照组的处理是          
③据此实验结果可推知水平放置的植物根向重力生长的原因是:高浓度的生长素诱导产生了乙烯,从而          。
