（二）凭着一颗火热的心1970年春天，张海迪随着下放的父母，来到莘县十八里铺尚楼村。
她多想迈开双腿，扑向那翠绿欲流的万顷麦田，劳动时，让汗水流进泥土，去滋养那饱鼓鼓的麦粒。
但是，她不能！她只能一个人坐在轮椅上，或躺在床上，留在静寂的小院里。
有时不免黯然泪下……有一天，跟海迪比邻而居的一位大娘半边脸肿了，原来她牙疼病又犯了。
又有一天，村里一个孩子病了，没多久却死了。
海迪真想去探望患病的大娘和失去孩子的家长。
“我能不能帮助乡亲们干一点什么呢？”十五岁的海迪想。
她请求爸爸买来一盒银针，一本《针灸学》，一本《人体解剖学》。
张海迪不管父母的劝说和医生的警告，总是日夜苦读，把两本书读了一遍又一遍。
然后，她擎起一枚银针，在动物身上进行试验，又在自己躯体上那尚有感觉的部位进行试验。

初二数学一到三单元练习题
初二数学一到三单元练习题本文为初二数学一到三单元的相关练习题，帮助同学们巩固所学内容。
以下为练习题及详细解答。
一、选择题1. 已知a = 3，b = 4，c = 5，则下列哪个等式成立？A. a + b = cB. a - b = cC. a * b = cD. a / b = c答案：A. a + b = c解析：将a、b、c的值代入选项，只有选项A成立，即3 + 4 = 5。
2. 若一个多面体的顶点数为12，棱数为15，则它的面数是多少？A. 5B. 6C. 7D. 8答案：C. 7解析：根据欧拉公式：顶点数 + 面数 - 棱数 = 2，代入已知的顶点数和棱数，得到：12 + 面数 - 15 = 2，解方程可得面数为7。
3. 一根长为2.4米的绳子，剪成3段，其中一段长度是0.8米，另外两段的长度之和是多少？A. 1.2米B. 1.6米C. 1.8米D. 2米答案：C. 1.8米解析：用2.4米减去已知一段0.8米的长度，得到剩余的长度为1.6米，根据题意，剩余长度被另外两段分成，故两段的长度之和为1.6米。
二、填空题1. 简化下列代数式：6x + 3y - 2x + 4y + 5x - y答案：9x + 6y解析：将相同项合并，得到6x - 2x + 5x + 3y + 4y - y = 9x + 6y。
2. 在一个等差数列中，首项为6，公差为3，第十项的值为多少？答案：(10 - 1) * 3 + 6 = 33解析：根据等差数列的通项公式an = a1 + (n-1)d，将已知数值代入得到：10项的值为6 + (10-1) * 3 = 33。
三、解答题1. 用最便捷的方法计算：45 * 36答案：1620解析：使用竖式乘法计算，如下所示：45× 36-----270（45 * 6）+ 810（45 * 30）-----16202. 解方程：2x + 5 = 15答案：x = 5解析：将方程转化为一元一次方程的标准形式，得到2x = 15 - 5，化简得2x = 10，再除以2得到x = 5。
