去掉Imgae和它下面div之间的空隙
<img/>后来才发现,这空隙并不是来自图像也不是来自下面的div,而是由它们之间的空格或换行字符引起的, 有两种办法可以解决这个问题:
<div>
......
</div>
1、把图像和div的tag放在同一行上,之间不要有任何字符:
<img/><div>2、HTML代码可以不动,而是用CSS进行调节.

美国之音慢速英语节目(Special English)简介
(MUSIC)
The Guggenheim opened in October of nineteen fifty-nine. That same month, the Voice of America began to broadcast special programs for English learners. Some language experts thought the idea would fail. But millions of listeners welcomed Special English.
Special English is read one-third slower than VOA's other English programs. The slower speed is combined with an extra effort to make the writing easy to understand.
Most of the words come from a vocabulary list that gets updated about every ten years. It began with one thousand words. Today it has about five hundred more. But writers can use any other words they need to report a story if the meaning is clear.
VOA Special English is an example of a controlled language. Another example is called Simplified Technical English. This language was developed to make it easier to understand and translate documents used at aircraft repair centers around the world.
Special English is popular because it helps people learn American English while they learn about world news, science, American life and other subjects. The first broadcast was ten minutes of news to Europe, Africa and the Middle East.
There was no special announcement. Announcer Paul Parks just said, "Here is the news in Special English." Feature programs were added later, starting with Special English versions of short stories by famous writers. That program, AMERICAN STORIES, can be heard each Saturday.
Today, Special English writers do a lot more original reporting and the programs are more lively. But one thing has never changed. Special English has a loyal following -- in homes, cars and classrooms throughout the world.
Some people are second-generation fans whose own children are now growing up with Special English. And not just on radio, but also TV and the Web: voaspecialenglish.com is one of VOA's most heavily visited sites.
Visitors can read and listen to programs, write comments, find shows they missed and sign up to receive programs by weekly e-mail. They can download MP3s and podcasts and access the Word Book. And they can watch videos in Special English. There is also voaspecialenglish.com/mobile. And Special English is expanding into social media. The goal, as always, is to follow English learners wherever their interests take them.

从博客网页中直接收听美国之音慢速英语节目
美国之音(VOA)以其全面、及时和相对客观而著名。它的慢速英语(Special English)尤其受到非英语国家听众的喜爱,除了用收音机之外,通常我们可以去美国之音慢速英语的网站下载或者直接收听,前提是电脑中已经安装了适当的媒体播放器。其实,我们也可以利用美国之音所提供的慢速英语节目的MP3链接,从你的博客网页或者其它任何网页中直接收听美国之音的慢速英语(Special English)节目。这样网页的读者就可以更方便地收听VOA慢速英语节目了。
方法很简单,把下面这段代码贴到你网页代码文件中适当的地方就可以了。
<object codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" height="27" width="400" align="middle" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"><param name="_cx" value="10583"><param name="_cy" value="714"><param name="FlashVars" value=""><param name="Movie" value="http://www.google.com/reader/ui/3247397568-audio-player.swf?audioUrl=ftp://8475.ftp.storage.akadns.net/mp3/voa/english/spec/special_english.mp3"><param name="Src" value="http://www.google.com/reader/ui/3247397568-audio-player.swf?audioUrl=ftp://8475.ftp.storage.akadns.net/mp3/voa/english/spec/special_english.mp3"><param name="WMode" value="Window"><param name="Play" value="0"><param name="Loop" value="-1"><param name="Quality" value="High"><param name="SAlign" value="LT"><param name="Menu" value="-1"><param name="Base" value=""><param name="AllowScriptAccess" value="never"><param name="Scale" value="NoScale"><param name="DeviceFont" value="0"><param name="EmbedMovie" value="0"><param name="BGColor" value=""><param name="SWRemote" value=""><param name="MovieData" value=""><param name="SeamlessTabbing" value="1"><param name="Profile" value="0"><param name="ProfileAddress" value=""><param name="ProfilePort" value="0"><param name="AllowNetworking" value="all"><param name="AllowFullScreen" value="false"><embed type="application/x-shockwave-flash" src="http://www.google.com/reader/ui/3247397568-audio-player.swf?audioUrl=ftp://8475.ftp.storage.akadns.net/mp3/voa/english/spec/special_english.mp3" allowscriptaccess="never" quality="best" bgcolor="#ffffff" wmode="window" flashvars="playerMode=embedded" pluginspage="http://www.macromedia.com/go/getflashplayer" height="27" width="400"></embed></object>
看起来,听起来就是下面这个样子,因为美国之音慢速英语节目的MP3链接会自动更新,你总会听到最新的节目:
其实,这是Google Reader里的基于Adobe Flash的MP3播放器,它有音量控制,自动检测音乐文件长度并显示播放时间,用起来很方便。你只要把audioUrl的值替换成你想要播放的MP3文件的链接,它可以播放任何MP3文件,就是一个镶嵌于网页的MP3播放器。
