(1-1/2)+(1/2-1/3)+(1/3-1/4)+···+（1/2009-1/2010 To find the sum of the given series, we need to add all the terms together. (1 - 1/2) + (1/2 - 1/3) + (1/3 - 1/4) + ... + (1/2009 - 1/2010) We can simplify each term by finding the common denominator. 1 - 1/2 = 2/2 - 1/2 = 1/2 1/2 - 1/3 = 3/6 - 2/6 = 1/6 1/3 - 1/4 = 4/12 - 3/12 = 1/12 We can observe that each term follows this pattern - the denominator of the second fraction becomes the denominator of the first fraction in the next term. So, the series can be written as: 1/2 + 1/6 + 1/12 + ... + 1/2009 To find the sum of this series, we need to find the common denominator of all the fractions. The common denominator of 2, 6, 12, ..., 2009 will be the least common multiple (LCM) of these numbers. Calculating the LCM of these numbers is a bit lengthy. Instead, we can find the LCM of 2, 3, 4, ..., 2010, and then divide by the LCM of 2, 3, 4, ..., 2009. LCM(2, 3, 4, ..., 2010) / LCM(2, 3, 4, ..., 2009) = 2010 / 2 = 1005 So, the common denominator is 1005. To add the fractions, we need to express them with the common denominator: 1/2 = (1/2) * (1005/1005) = 1005/2010 1/6 = (1/6) * (1005/1005) = 167.5/2010 1/12 = (1/12) * (1005/1005) = 83.75/2010 Now we can add: 1005/2010 + 167.5/2010 + 83.75/2010 + ... + 1/2009 We can observe that the denominators of the fractions form an arithmetic sequence, and the numerators follow the same pattern. Using the formula for the sum of an arithmetic sequence: Sum = (first term + last term) * number of terms / 2 In this case, the first term is 1005/2010, the last term is 1/2009, and the number of terms is 2010. Sum = (1005/2010 + 1/2009) * 2010/2 Sum = (1005/2010 + 1/2009) * 1005 Sum = (1005 * 2009 + 1 * 2010) / 2 Sum = (2019955 + 2010) / 2 Sum = 2021965 / 2 Sum = 1010982.5 Therefore, the sum of the given series is 1010982.5.底座的安装非常简便，将其与支架用免工具螺丝轻松固定即可。 此次科普活动，以“安全用药健康为民”为主题，通过发放宣传资料、现场答疑解惑的方式，围绕群众普遍关注的药品安全问题，尤其是针对当前甲流和支原体感染高发感染时期，就如何使用感冒药、消炎药进行科普。
蜂蜜香酥花生的配方 材料: - 1杯花生 - 3汤匙蜂蜜 - 1汤匙白糖 - 1/2茶匙盐 - 1/4茶匙香草精 步骤: 1. 预热烤箱至180摄氏度（350华氏度）。 2. 在一个大碗中，将蜂蜜、白糖、盐和香草精混合均匀。 3. 将花生加入混合液中，搅拌均匀，使每颗花生都均匀覆盖上糖浆。 4. 将覆盖着糖浆的花生均匀铺在烤盘上。 5. 将烤盘放入预热好的烤箱中，烘烤10-12分钟，直到花生金黄色和香脆。 6. 将烤好的花生从烤箱中取出，稍微晾凉。 7. 完全冷却后，将香酥花生放入罐中保存。 享用时，可以作为零食直接食用，也可以用作配料加入糕点、曲奇饼干或果仁巧克力中。市离退休干部服务中心副主任张波、许庄街道办事处副主任马峥等领导出席开班仪式。
