Being able to read a person's thoughts using an implant, for example, raises the possibility of being able to write a person's thoughts for them.
例如，如果能够使用一个内置装置读出一个人的思想，那么就有可能把一个人的思想写入他人的脑中。
As in the previous example, the print function raises an exception, because the file was not open for writing.
正如之前的例子所示，print函数抛出了一个异常，原因是文件尚未打开以供写入。
For example, you might want an object that raises events to be able to call different event handlers under different circumstances.
例如，您可能想让一个引发事件的对象能够在不同的环境下调用不同的事件处理程序。
