看电影学英文，但不能浮光掠影，精读对英语水平的提高是非常重要的，如何才能把字幕变成可以阅读的文档呢。下面就是解决办法。
01 .srt 的字幕可以直接用文本软件编辑，我用的Eidtplus以哈佛大学公开课《如何才能做到公正》的第四集为例，原文档如下：引文开始——700:00:17,110 --> 00:00:19,540哈佛大学公开课800:00:19,560 --> 00:00:23,440公正课迈克尔·桑德尔教授主讲900:00:24,050 --> 00:00:27,050第七讲 《我的地盘我做主》1000:00:31,700 --> 00:00:33,650今天 我们开始讲约翰·洛克Today, we turn to John Locke.1100:00:39,320 --> 00:00:46,590表面上看 洛克是自由主义的强力盟友On the face of it, Locke is a powerful ally of the libertarian.1200:00:47,020 --> 00:00:53,630与当今自由主义者一样 他首先认为First, he believes, as libertarians today maintain,1300:00:54,380 --> 00:01:01,280有些基本的个人权利至关重要that there are certain fundamental individual rights that are so important1400:01:01,280 --> 00:01:05,480以至任何政府 甚至代议政府that no government, even a representative government,——引文结束可以看到，其中有我们不想要的中文，还有大量的时间线代码，我们需要将二者清除，才能得到自己想要的英文内容。复制到word2007，crtl+h 调出替换命令，在“查找内容栏”输入“[一-龥]”（中文括号内的内容） ，并选择“使用通配符” 替代内容不填这个操作的结果是，将word文档里的中文批量去掉。处理以后成这个样子引文开始——700:00:17,110 --> 00:00:19,540800:00:19,560 --> 00:00:23,440·900:00:24,050 --> 00:00:27,050《 》1000:00:31,700 --> 00:00:33,650·Today, we turn to John Locke.1100:00:39,320 --> 00:00:46,590On the face of it, Locke is a powerful ally of the libertarian.1200:00:47,020 --> 00:00:53,630First, he believes, as libertarians today maintain,1300:00:54,380 --> 00:01:01,280that there are certain fundamental individual rights that are so important1400:01:01,280 --> 00:01:05,480that no government, even a representative government,——引文结束下面我们要将时间线代码去掉，再次按ctrl+h 调出替换窗口，在查找内容栏输入“[0-9]@^13[0-9:,^32>-]@^13”选择“使用通配符” 替代内容为空，确定后，结果如下。引文开始——·《 》·Today, we turn to John Locke.On the face of it, Locke is a powerful ally of the libertarian.First, he believes, as libertarians today maintain,that there are certain fundamental individual rights that are so importantthat no government, even a representative government,——引文结束现在我们已经得到了全部的英文，下面需要的是做进一步的编辑，首先将未批量删除的书名号去掉，不述。其次是删除空段，批量删除空段的办法还是ctrl+h 调出替换窗口，选择“更多”，看到特殊格式，点第一个“段落”，显示为^p，替代栏为空，确定，结果如下：· · Today, we turn to John Locke. On the face of it, Locke is a powerful ally of the libertarian. First, he believes, as libertarians today maintain, that there are certain fundamental individual rights that are so important that no government, even a representative government,接下来进一步编辑，从带句点的地方分段（查找内容为“.” 替代内容为“.^p”），并去除多余空格。最终结果如下：Today, we turn to John Locke. On the face of it, Locke is a powerful ally of the libertarian.First, he believes, as libertarians today maintain, that there are certain fundamental individual rights that are so important that no government, even a representative government,这样一个完整的字母文档就出来了。学英语还是很方便的。
