Tina was a seventeen-year-old girl who always wore a bright smile. She suffered from a disease and had to use a walker most of the time. Maybe it was because she looked     and people didn’t know how to come near toher. Tina usually broke the ice with people she met with a big “      ”
In one class, I gave the students an assignment (作业) to        a poem. I only made the assignment worth a very small part of their total grade since I knew most of my        would not do it anyway. In the class, one by one each student      to correctly recite (背诵) the poem. Finally, angry and half joking, I said that the next student who        recite the poem had to do three push-up (俯卧撑). To my         , Tina was next. She used her walker to move to the front of the class.       she recited, she made a mistake. Before I could say a word, she        her walker and started doing push-ups. I wanted to say, “Tina, I was just        !”But she      , continued the poem and she finished the rest perfectly.
When she finished, a student asked, “Tina, why did you do that? It’s not an important assignment!”
“Because I want to be like you guys! To be        .” Tina said.
Silence fell on the whole room when another student cried out, “Tina, we’re not normal! We are teenagers!
We get in      all the time.”
“I know,” Tina said as a big      spread across her face. The rest of the students laughed, too.
Tina got only a few        that day, but she got the love and respect of her classmates. To her, that was
worth a lot more than a grade.

问答题

2010年2月在加拿大温哥华举行的第2l届冬季奥运会上，冰壶运动再次成为人们关注的热点，中国队也取得了较好的成绩．如图，假设质量为m的冰壶在运动员的操控下，先从起滑架A点由静止开始加速启动，经过投掷线B时释放，以后匀减速自由滑行刚好能滑至营垒中心O停下．已知AB相距L₁，BO相距L₂，冰壶与冰面各处动摩擦因数均为μ，重力加速度为g．

（1）求冰壶运动的最大速度v_m．

（2）在AB段运动员水平推冰壶做的功W是多少？

（3）若对方有一只冰壶（冰壶可看作质点）恰好紧靠营垒圆心处停着，为将对方冰壶碰出，推壶队员将冰壶推出后，其他队员在BO段的一半长度内用毛刷刷冰，使动摩擦因数变为

μ．若上述推壶队员是以与原来完全相同的方式推出冰壶的，结果顺利地将对方冰壶碰出界外，求运动冰壶在碰前瞬间的速度v．
