    The 87^th Academy Award nominations（提名）were announced on Jan 15,and The Grand Budapest Hotel stood out as a favorite with nine nominations, including Best Picture. Check out some other Best Picture nominees to see if you missed any of last year's top Hollywood films.

The Imitation Game

    This historical thriller is about British computer scientist, Alan Turing (Benedict Cumberbatch), the father of artificial intelligence. At the start of World War Ⅱ, Turing was asked to join a select team of mathematical geniuses to decode（解码）the system the Nazis used to send military messages. Besides the actual breaking of the code, Cumberbatch's portrayal（扮演）of Turing's personality, a mixture of decency（正派）and shyness, is also a highlight of the movie.

Birdman

    This dark comedy film is about how Riggan Thomson, a faded star once famous for his superhero roles, struggles to regain fame. American actor Michael Keaton, 63, who has a similar experience to Thomson's, plays the leading role.

Selma

    A stellar cast(主要演员) including talk show queen Oprah Winfrey may be one reason to see Selma. But that the film focuses on Martin Luther King Jr.'s struggle for civil rights also makes it worth viewing. Based on the 1965 Selma to Montgomery voting rights marches, the film is a chronicle(编年史) of King's(David Oyelowo) campaign for political rights for African-American people.

The Theory of Everything

    We know English theoretical physicist Stephen Hawking for his significant scientific discoveries, especially his black hole theories. This biographical film reveals the scientist's (played by Eddie Redmayne) secret romantic relationship with Jane Hawking (Felicity Jones), whom he meets and falls in love with at Cambridge and who later becomes his first wife.

Boyhood

    American Director Richard Linklater did an experiment in this film, using the same cast for l2 years to record a boy's growth. In two and a half hours, we see Mason, a Texas boy from a divorced family, grow from 6-year-old boy to a freshman in college.

《拒绝句号》

冯翼才

      一定会有一些朋友反对我这个标题。他们会说多好的句号啊!句号表示一种完成，一种圆满，一种有志者事竟成，一种成果与收获，或者干脆把这溜圆的句号看成一个个饱满的果实。它们还会问我，当你完成一部几十万字的长篇小说，在那最末一行画上一个句号时，难道你没有如释重负、飘飘欲仙般的感受?没有那种大功告成后该痛快干杯的喜悦吗?

　　当然，这样的句号我也喜欢。但人生还有另一种句号。

　　打个比方，你在一条路上走，走着走着，忽然有一种“尽头感”时，这句号就隐隐出现，如果你停下来，你足下就清晰地现出一个句号。这条路可不是做一件事时那短短的距离，它是人生追求的路、艺术探索的路和事业奋斗的路。这路原本无止无休，你在任何一处都可以起步，踏上征程;你也可以在任何一处画个句号，退了出来。无论什么都可以成为句号的缘故，那精疲力竭的放弃、自寻清闲的逃逸、江郎才尽的低头认输，乃至收获后的自满自足，甚至在目标达到之后，辉煌的目标也会化为一个句号，尽管这句号闪闪发光。句号，就是停止，就是终结，就是事物最终变为有限的、死去的符号。

　　我说的是这种句号。可怕的是，这些句号总是不知不觉地出来。你呢，不知不觉地完结。想想看，你曾经做过了哪些有益的事?究竟是什么时候并怎样弃你而去的?句号往往又是和人的自足、人的彻悟、人的惰性连在一起的。所以句号大多是人心甘心情愿给自己画上的。人随时可能舒舒服服给自己画个句号，休止了自己。

       因而，我害怕句号。我对句号保持着近乎神经质的警惕。在与句号的斗争中，我一边感到生命的活力，常常闻到自身肌肉搏斗后散发出热烘烘的清香;一边认识到这原是生命存在所必须进行的奋争，也是与自身惰性与保守的对抗。当然，它何其艰难!跨过每一个句号，都需要付出双倍的力量，其中一半是创造力。然而，只要在人生或艺术的道路上，消灭一个句号，便开始一段崭新的充满诱惑的路。我们还会发现，被我们拒绝和消灭的句号，最终竟然会变成逗号。
