考研英语重在基础，建议广大考生在了解考研英语大纲的前提下，首先积累英语词汇量，并通过做阅读理解、翻译、写作等练习在词义方面加以提升，然后再考虑学习掌握答题技巧。当然，我们知道英语知识的复习是一个长期积累的过程。让我们跟随何凯文老师的每日一句。所谓：不积跬步，无以至千里;不积小流，无以成江海。坚持就是胜利!

　　奥巴马最近在Knox College 做的演讲确实很火，除了经济学人在关注之外，美国最有影响力的新闻博客网站赫芬顿邮报(The Huffington Post)对这个演讲也有很多的报道，这里我给摘录了一些。大家会发现这个媒体的文风确实没有经济学人讲究，不过所谈的话题是很值得大家好好把握的。尤其是单词!

　　In a speech delivered at Knox College in Illinois,Barack Obama launched his final campaign: a campaign to revive the American Dream. The speech, less eloquent and windier than the best of Obama’s, told Americans a clear story and called on them to support a clear direction. TheWhite House promises that this will be the beginning of a campaign, not a one-off statement for the record. Obama finally called out the “faction of Republicans” that stands in the way of progress.
