选项 A、plane

C、plate
D、platform
答案D
解析 一个网页浏览器可以简单地看成一个终端仿真程序，它用来在屏幕上显示文本。一个普通的终端仿真程序和一个网页浏览器之间的两个最本质区别是，浏览器知道如何处理超链接(hyperlinks)，并且它有显示(displaying)图形文件的机制。显示图片、文本、穿梭于(navigate，航行)超链接之间——这就是网页浏览器(Web browser)99％的价值所在。但并不是说各生产商不会到处去寻求一个花哨无用的功能附加到他们的浏览器里。曾记否，当浏览器中的媒体信息流量很大时，你如果不及时从你的书签菜单项中删除你喜欢的网页时只会带来混乱的结果?还记得什么时候客户端的Java小程序曾被认为是应用开发平台(platfom)的首选吗?还记得框架以及它们所有乱七八糟的负面效应吗?
