EXCEL统计各班大于100分的人数
2007及以上，用COUNTIFS函数；2003及以上版本，用SUMPRODUCT函数。
班级在A列，分数在C列，1、COUNTIFS函数：将条件应用于跨多个区域的单元格，并计算符合所有条件的次数。
公式如下：=COUNTIFS(A:A,班级名称,C:C,>100)2、SUMPRODUCT函数用于：将满足条件的数组间对应的元素相乘，并返回乘积之和。
公式如下：=SUMPRODUCT((A:A=班级名称)*(C:C>100))
要一篇200字的《对老师的意见》
远程桌面：所有版本的 XP，包括家庭版，都支持远程帮助。
远程帮助允许系统管理员远程连接到一台客户电脑，帮助其解决问题。
但只有专业版支持远程桌面功能。
该功能有两个很明显的作用：经常出差的专家需要远程登陆到他们公司的电脑，和远程管理客户端和网络。
你可以通过任何一个支持Terminal Services（）客户端的（例如Win 98），来访问 XP远程桌面。
多处理器支持： XP专业版可以支持两个CPU，而家庭版只能支持一个。
多显示器支持：Windows XP专业版可以支持多至9个显示器，而家庭版只能支持一个。
自动系统恢复（Automated System Recovery，ASR）：微软在Windows XP家庭版中取消了备份工具。
原因大概是想使微软新推出的ASR更好地集成到备份功能中。
ASR可以帮助系统从灾难性的错误（例如系统不能启动）恢复到原来的工作状态。
与针对消费者市场的系统恢复功能不同，ASR实际上并不是自动的。
你必须在Windows XP的备份工具中打开该功能。
动态磁盘支持。
Windows XP专业版支持动态磁盘，但家庭版不支持。
家庭版只支持标准的简单磁盘类型（Simple Disk）。
动态磁盘只能在Windows 和Windows XP中使用，但不能在手提式电脑上使用。
另外，家庭版不包含逻辑磁盘管理器。
传真：家庭版没有集成传真功能。
IIS\\\/PWS：家庭版不包含IIS网页服务器。
安全性：加密文件系统（Encrypting File System，EFS）：Windows XP专业版支持EFS。
EFS允许你加密个人文件或者文件夹。
其他用户不能打开经EFS保护的文件和文件夹。
文件级访问控制：系统管理员可以限制某些网络资源的访问，例如服务器、目录、文件等。
只有Windows XP专业版才支持文件级访问控制。
C2验证：微软要求Windows XP专业版通过C2安全验证，而家庭版则不需要。
管理：域：家庭版不能登陆Active Directory（活动目录）域，因此，你在家庭版中也看不到域向导。
IntelliMirror：微软在IntelliMirror中使用了大量的设置管理技术。
这些技术在家庭版中都没有应用到。
IntelliMirror包括用户数据管理，软件安装、修复、升级、删除中央管理，用户设置管理，远程安装服务等。
企业特性：多语言支持：只有Windows XP专业版能够不需要多次安装便可支持多种语言。
Syspre（系统准备）支持：Windows XP专业版支持Syspre工具，而家庭版则不支持。
