在Word中只删除英文保留中文的方法
在Word的“编辑”菜单选“查找”（或直接按ctrl+F快捷键），选“替换”标签，然后在查找内容后面输入^$，替换后面的内容留空，然后点击“全部替换”按钮即可删除所有英文字母。
此外，也可以在查找和替换面板下面点“高级”按钮，在“特殊字符”按钮弹出列表那里选择“任意字母”，这是就看到查找内容文本框后面自动输入了“^$”字符。
在Word中只删除数字的方法
同上面的方法调出查找替换框，在“查找内容”后面输入^#，“替换为”后面留空，然后按“全部替换”按钮即可清除文档中的所有阿拉伯数字。
在Office Word中只删除中文保留英文的方法
调出查找替换框，在“查找内容”后面的框里输入[!^1-^127]
（注意要输入中括号），同时，点开“高级”按钮，将“使用通配符”前面的复选框勾上，最后点击“全部替换”按钮即可删除文档中的所有中文汉字。
