忆父亲

    ①父亲去世已经一个月了。这一个月里,又有电影或电视剧的制片人员,到我家来请父亲去当群众演员。他们走后,我就独自静坐,回想起父亲当群众演员的几件小事。

    ②一次,我从办公室回家,经过北影一条街,见父亲端端地坐在台阶上。而导演们正在摄影机前指手画脚地议论什么,不像再要群众演员拍戏的样子。时已中午,我走到父亲跟前,说:“爸爸,你还坐在这儿干什么呀?回家吃饭吧!”父亲说:“不行。我不能离开。”我问:“为什么?”父亲回答:“我们导演说了,别的群众演员没事了,可以走了,但这位老人不能走。他可能还有任务。”父亲的语气中,很有一种自豪感似的。

    ③父亲坐得很特别。那是一种正襟危坐。他身上的演员服,是一种褐色绸质长袍。他将长袍的后摆,掀起来搭在背上;而将长袍的前摆,卷起来放在膝上。他不倚墙,也不靠什么,就那样子端端地坐着,分明地,他惟恐那长袍沾了灰土或弄褶皱了。

    ④父亲不肯离开,我只好去问导演。导演却已经把我的老父亲忘了,一个劲儿向我道歉。

    ⑤记得有天晚上,我们一家人一块儿包饺子。父亲擀皮儿。忽然,父亲喟叹一声,喃喃地说:“唉,人啊,活着活着,就老了……”一句话,使我、妻、母亲面面相觑,全家怪纳闷怪伤感的。睡前,我试探地问:“爸,你今天不高兴了么?”父亲说:“不!我很高兴啊!”我说:“那你为什么在包饺子的时候叹气,还自言自语‘老了老了’的哩?”“哎,那是一句台词,”父亲笑了笑说,“昨天,我们导演指示——给这老爷子一句台词!连台词都让我说了,那不真算是演员了么?我那么说你听着可以么?……”我恍然大悟,原来父亲是在                。

    ⑥我就说:“爸,我的话,也许你又不爱听。其实你愿意怎么说都行!反正到时候,不会让你自己说的,会找个人替你配音……”这下父亲真的不高兴了,便以教训的口吻说:“要是都像你这种态度,那电影能拍好么?一句话,光是说说的事儿?脸上的模样要是不对劲,不就成嘴上主阴,脸上作晴了么?”

    ……

    ⑦是啊,父亲所“演”的,不过就是些迎着镜头走过来或背着镜头走过去的群众角色。走得时间最长的,也不过就十几秒钟。然而与父亲“合作”过的导演们说起父亲来,都赞不绝口。

根据短文理解,选择正确答案。

    We're always looking for well­written reviews of books, music, movies, television shows, websites, video games and other products. When writing a review, concentrate on exactly what you liked or didn't like. Give examples of strengths and weaknesses,be descriptive and provide background information on an author,director,actor or musician,if possible. Find professional reviews in magazines or newspapers and see how reviewers deal with their topics,but be sure to express your own voice in your review.

    Grammar Hint for Reviews:When describing a book,movie, album or anything else,use the present tense.

Book Reviews

    Discuss an author's technique,strengths and weaknesses instead of focusing on the plot. Does the story flow? Is there a strong sense of character and place?Did you stay up until dawn to finish it?Is it good reading for teenagers?What influence did it have on you and why?If you've read other books by the same author, discuss how this book compares.

Movie Reviews

    Think of the major Oscar categories and consider the performances, music, lighting and setting, etc. Do these work together? Did some hold up while others didn't? If the movie is based on a book, discuss whether one is better than the other and why. If the movie is a remake, compare the film to its original.

    Remember that a well­written movie review should discuss strengths and weaknesses. Some readers may not have seen a movie yet, so don't give away an exciting scene or the ending!

College Reviews

    Begin by providing an overview of the college,including location,size and a description of the campus and/or dorm life. Think about all aspects of your college visit. What academic,athletic and after­class programs are available? What are the students like? What makes the college different from others? Every school has strengths and weaknesses. Be objective. Consider what the school has to offer and who might enjoy or benefit the most from attending there.
