2 阅读理解。 As a music teacher for twenty-seven years, I have always known that music touches the soul. It can break through all kinds of barriers to reach students in a very special way. It can be the means for each child to find their light. A few years ago, I was blessed with the opportunity to teach pre-school students one afternoon a week. One of my most memorable students was Vanessa. She was five years old, had difficulty walking, and could not speak. We mostly sat on the floor for our music lessons and Vanessa liked to sit on my lap. One of her favorite songs was John the Rabbit. It was a call and response song where I sang the call and the students clapped two times while singing the repeating phrase,"Oh, yes!" Vanessa liked to put her hands together with mine and clap with me. We performed that song during every class, Vanessa and I clapping together. She never said or sang a word. One day late in the school year, when the song was finished, Vanessa turned around, looked me in the eye, clapped her tiny hands two times and said the words "Oh, yes!" I opened my mouth and for that moment I was the one who could not speak. Through music, we had made a connection. Several years later, I came across Vanessa on the street in town. I stopped my car and waved to say hello. She waved back with a big smile on her face and then clapped her hands two times, mimicking (模仿) the song we had performed in our music class. This precious little girl, through her connection with music, left an impression on me that will last forever. Every child has the ability to learn and grow. It is up to us educators to discover the way to reach each and every one of our students. We all must find each child"s light. 1. The author thinks music _____. A. can make children calm down B. can connect heart to heart C. is difficult for pre-school students D. is a good means to find a job 2. According to the second paragraph, Vanessa ______. A. got used to singing songs B. was too shy to speak C. was the youngest in the class D. enjoyed the author"s class 3. When Vanessa spoke the words "Oh, yes!", the author felt ______.

Disabled children are natural music lovers. C. Teachers should find a way to discover students" light. D. A good educator ought to help students learn through music.

7 “嫦娥奔月”是中国家喻户晓的神话故事，我国于2004年制定了“嫦娥工程”。继“嫦娥一号”和“嫦娥二号”卫星成功发射后，2012年3月13日，国家科防局发布消息，中国探月工程二期“嫦娥三号”任务已正式由初样研制转入正样研制阶段，计划于2013年发射。嫦娥三号任务是探月工程二期的关键任务，将突破月球软着陆、月面巡视勘察、月面生存、深空测控通信与遥操作（如图15），将是我国首次实现在地外天体上的软着陆。这极大地提高了同学们对月球的关注程度，以下是某同学就有关月球的知识设计的两个问题，请你解答：（1）若已知地球半径为R，地球表面的重力加速度为，月球绕地球运动的周期为，且把月球绕地球的运动近似看作是匀速圆周运动。试求出月球绕地球运动的轨道半径（2）若某位宇航员随登月飞船登陆月球后，在月球某水平表面上方高处以速度水平ν 0抛出一个小球，小球落回到月球表面的水平距离为。已知月球半径为，万有引力常量为。试求出月球的质量。
8 在研究并行计算的基本算法时，有以下简单模型问题：用计算机求n个不同的数ν 1，ν 2，…，ν n的和 =ν 1+ν 2+ν 3+…+ν n。计算开始前，n个数存贮在n台由网络连接的计算机中，每台机器存一个数，计算开始后，在一个单位时间内，每台机器至多到一台其他机器中读数据，并与自己原有数据相加得到新的数据，各台机器可同时完成上述工作。为了用尽可能少的单位时间，使各台机器都得到这n个数的和，需要设计一种读和加的方法.比如n=2时，一个单位时间即可完成计算，方法可用下表表示：（Ⅰ）当n=4时，至少需要多少个单位时间可完成计算？把你设计的方法填入下表（Ⅱ）当n=128时，要使所有机器都得到，至少需要多少个单位时间可完成计算？（结论不要求证明）
