人民解放军百万大军横渡长江

（新华社长江前线22日22时电）  人民解放军百万大军，从一千余华里的战线上，冲破敌阵，横渡长江。西起九江（不含），东至江阴，均是人民解放军的渡江区域。二十日夜起，长江北岸人民解放军中路军首先突破安庆、芜湖线，渡至繁昌、铜陵、青阳、获港、鲁港地区，二十四小时内即已渡过三十万人。二十一目下午五时起，我西路军开始渡江，地点在九江、安庆段。至发电时止，该路三十五万人民解放军已渡过三分之二，余部二十三日可渡完。这一路现已占领贵池、殷家汇、东流、至德、彭泽之线的广大南岸阵地，正向南扩展中。和中路军所遇敌情一样，我西路军当面之敌亦纷纷溃退，毫无斗志，我军所遇之抵抗，甚为微弱。此种情况，一方面由于人民解放军英勇善战，锐不可当；另一方面，这和国民党反动派拒绝签订和平协定，有很大关系。国民党的广大官兵一致希望和平，不想再打了，听见南京拒绝和平，都很泄气。战犯汤恩伯二十一日到芜湖督战，不起丝毫作用。汤恩伯认为南京江阴段防线是很巩固的，弱点只存在于南京九江一线。不料正是汤恩伯到芜湖的那一天，东西防线又被我军突破了。我东路三十五万大军与西路同日同时发起渡江作战。所有预定计划，都已实现。至发电时止，我东路各军已大部渡过南岸，余部二十三日可以渡完。此处敌军抵抗较为顽强，然在二十一日下午至二十二日下午的整天激战中，我已歼灭及击溃一切抵抗之敌，占领扬中、镇江、江阴诸县的广大地区，并控制江阴要塞，封锁长江。我军前锋，业已切断镇江无锡段铁路线。

    Gadgets that make study fun

    Now in a world piled high with smart phones, tablets and e-readers, technology has entered the classroom in ways unimaginable. Taking classes can be fun too. All you have to do is swipe your fingers on your phone screen and download some apps, which can make your study more fun and efficient. Balancing study and play in a college setting has never been easy-and with the following few apps, it'll be tough to tell the two apart.

    Evernote

    Use: note-taking

    Can be used on: Phone/iPad/iPod touch, Android, BlackBerry, Palm OS and     Windows, Phone 7

    Price: free

    It's hard to imagine that with all the magical gadgets, the eager, studious types would still take out a notepad, a pencil, and a highlighter—and take notes in class. While it's not an actual planner or a calendar App, if you take notes to stay organized, then Evernote is for you．The main thing about Evernote is that all of your notes are automatically sent into the cloud---and then you can access them from any web-connected computer via the Evernote app or a web browser. Evernote also supports audio and photo notes-rather handy if you want to record your lecture or take photos of any projected notes. But, of course, ask for permission first.

    Wikipanion

    Use: research database

    Can be used on: iPhone/iPad/iPod touch

    Price :free ( Wikipanion Plus for $4．99,or 31.87 yuan )

    Now, you don't necessarily have to go to a library or anywhere with computer services to do research work for your paper anymore. You can get access to the research databases just on your smart phone or tablet. Wikipanion gives you a simplified version of Wikipedia without leaving out any of the site's extra features. The normal links that you'd see to each section of an article are no longer on the main screen. Instead, there's small icon located at the bottom of the App, which can be used to access all the sections of an article. You can also open the links in Safari(苹果浏览器). According to the developers' site, loading Wikipedia pages with Wikipanion is a lot faster than accessing the Wikipedia site from the iPhone's browsers. To be honest, we agree.
