Section Ⅱ　Lesson 1 [对应学生用书P101] From Page to Screen by James Hope(Arts journalist) Reading a book and watching a film are two very different experiences，but it's normal to have high expectations①when a film of a favourite book is made．②There are many times I have been pessimistic or even disappointed by a film of a book I love.Although highly regarded books do not always make good films，it is safe to say that great films may be made from not particularly good books③.(The Godfather immediately springs to mind④.) The source material for a film may be taken from classic⑤ novels，short stories，comic books⑥ and stage plays，as well as non­fiction⑦ such as biographies⑧ and autobiographies⑨，even those written by ghost writers⑩.All can work well，but why do many adaptations⑪ and indeed remakes fail with both cinema audiences and critics⑫？ And why do some adaptations get lower ratings⑬ than others? A key question is obviously how close to the original the film is.Since a typical film is only around two hours long，it becomes a question for screenwriters to decide what is appropriate for the screen and what to leave out⑭．Screenwriters take creative liberty⑮ and sometimes there may be changes to the plot，additions，and even different endings to please producers，directors and test audiences.I，like many people，have often left the cinema feeling “the film is not like the book”． Another problem area is the cast⑯.Finding actors acceptable to film audiences can mean the difference between success and failure.Readers of the book use their imaginations to visualise⑰ characters and have very definite⑱ ideas about how characters should look and sound⑲.This is where I think many film adaptations fall down⑳. Some books are just too difficult to be adapted for technical㉑ reasons，although films like Life of Pi are changing this idea.CGI(Computer Generated Image) technology has had a huge impact on㉒ the film industry㉓.It allowed the previously unfilmable to become a reality. One may think that it is the book writer who is in the best position to do film adaptations㉔.In fact，sometimes authors are very involved in㉕ the process and may even be the screenwriter.This can actually be a disadvantage because they may be too close to the material and find it difficult to adapt to㉖ a new form.At other times they are not，and there are instances where writers have been very unsatisfied with the film versions㉗ of their work㉘； Stephen King is an example of this.Even more extreme was novelist J．D.Salinger，who made sure no film versions of his popular novel A Catcher in the Rye could ever be made.In this situation，it is clear that viewers will not be disappointed㉙！ For me，anyway，it is always a bad idea to watch a film of a book you love. Despite the challenges，there have been some highly successful films made from popular books.For me，Jaws，Harry Potter and The Lord of the Rings all fit this category㉚.And possibly the best proof㉛ of a successful adaptation is the James Bond series，the majority of㉜ which has been adapted from the 007 novels of Ian Fleming.Perhaps unusually，audiences seem to accept that the actors who have played James Bond have changed so often，although everyone seems to have their favourite．㉝I know I do. ①expectation /ˌekspek'teIʃən/ n.期待，预期，预料 expect vi.&vt.期待；期望；指望 ②本句是一个复合句。其中but连接并列句；when引导时间状语从句 ③本句中it作形式主语，to do不定式作真正的主语，其中含有that引导的宾语从句 ④spring to mind 想到 ⑤classic /'klæsIk/ adj.经典的；古典的 ⑥comic books 漫画书；连环画 comic /'kɒmIk/ n.连环漫画；adj.喜剧的；滑稽的 ⑦non­fiction /ˌnɒn 'fIkʃn/ n.非小说；非小说类文学作品 ⑧biography /baI'ɒɡrəfI/ n.传记 ⑨autobiography /ˌɔːtəbaI'ɒɡrəfi/ n.自传 ⑩ghost writer 代笔人 ⑪adaptation /ˌædæp'teIʃən/ n.适应；改编；改编本 adapt vi.&vt.使适应；改编 ⑫critic /'krItIk/ n.批评家，评论家 ⑬rating /'reItI/ n.(电影、电视的)收视率排行榜；等级，程度 ⑭第一个what引导宾语从句，第二个what是疑问词加不定式短语作宾语 ⑮liberty /'lIbəti/ n.自由；自由权 ⑯cast /kɑːst/ n.演员阵容，全体演员 vt.投射(光或影) ⑰visualise /'vIʒuəˌlaIz/ vt.设想，想象 ⑱ definite /'defInət/ adj.清楚的；明确的 definitely adv.清楚地；明确地，肯定地 ⑲本句为how引导的宾语从句 ⑳fall down 跌倒；失败 ㉑technical /'teknIkəl/ adj.工艺的，科技的；技术上的 technique n.技巧，技术；手法 technically adv.技术上；专门地 ㉒have an impact on 对……有影响 ㉓film industry 电影业 ㉔adaptation改编版；适应 ㉕be involved in 包括……中，被卷入……中；涉及到…… ㉖adapt to 适应 ㉗version /'vɜːʃən/ n.版本 ㉘本句为where引导的定语从句 ㉙本句中it 作形式主语，that引导的从句作真正的主语 ㉚category /'kætIɡəri/ n.类别，种类，范畴 ㉛proof /pruːf/ n.证明；证据 ㉜the majority of 大多数 ㉝本句为主从复合句。其中that引导宾语从句；who引导定语从句；although引导让步状语从句 从书页到屏幕 詹姆斯·霍普(艺术记者) 读书和看电影是两种截然不同的体验。如果人们最喜欢的书籍被翻拍成电影，他们对电影的期待值自然更高，这种现象很正常。不止一次，我喜欢的书籍被拍成电影，我都不看好，甚至很失望。尽管高质量的书并不总是能拍出好看的电影，优秀的电影也可能来自不是那么好的书，说的倒是没错。(这让我马上想到《教父》。) 一部电影可以取材自经典小说、短篇小说、漫画书、舞台剧，也可以取自传记、自传等非小说作品，甚至是代笔人写的作品。这些素材都可以拍出很棒的作品，但为什么许多改编、翻拍的电影没能受到电影观众与评论家的好评呢？为什么有些改编作品的评分比其他作品低呢？ 显而易见，一个关键的问题在于这部电影与原作接近程度如何。由于一部典型的电影通常只有两小时左右，因此编剧们要决定书中哪部分适合银幕，哪部分不适合。对此编剧有一定的创作自由度，有时为了迎合制片人、导演、观众，会改动部分情节，甚至演绎不同结局。和很多人一样，我也经常在看完电影后感叹“这部电影和原作不一样”。 另一个问题是演员阵容。找到电影观众所接受的演员，有时决定着电影的成败。读者会通过自己的想象，将书中的人物形象化，并且对角色的外貌、声音他们都有明确的想法。我认为选择的演员不符合他们的想象，是很多电影改编失败的原因。 一些书由于技术原因很难拍成电影，虽然《少年派的奇幻漂流》等电影的出现正在改变这一问题。电脑生成动画技术对电影产业有重大影响，让以前无法拍摄的内容成为现实。 人们可能会认为，最适合改编电影的人应该是书籍作者本人。事实上，作者有时的确会参与改编，甚至可能担任电影编剧。但这其实有局限性，因为作者本人可能过于忠于书中内容，很难将其改编成一种新的形式。有时作者本人并不是电影编剧，于是出现了作者对自己作品所拍摄的电影版本非常不满意的情况。史蒂芬·金就是这样。小说家杰罗姆·大卫·塞林格更为极端，他永远不准自己广受欢迎的小说《麦田里的守望者》被拍成电影版本。如果是这样，读者就永远不会失望！不管怎样，我认为去看自己钟爱的书籍翻拍成的电影不会是个好主意。 尽管挑战重重，还是有一些改编自畅销书的电影取得了极大成功，例如《大白鲨》《哈利·波特》和《指环王》都是成功的案例。可能最好的例子是詹姆斯·邦德系列，该系列的大部分作品都改编自伊恩·弗莱明的《007》系列小说。系列影片中詹姆斯·邦德的扮演者经常换人，但观众们似乎也能接受，这让人难以相信。但我相信每位观众和我一样，都有自己最喜欢的那个扮演者。 [对应学生用书P103] Ⅰ.重点词汇 ◎核心单词 1．classic adj.经典的 n.名著；经典作品 2．comic n.连环漫画 adj.滑稽的 3．non­fiction n.非小说类文学作品 4．biography n.传记 5．autobiography n.自传 6．critic n.评论家，批评家 7．rating n.(电影、电视的)收视率排行榜；等级，程度 8．liberty n.自由；自由权 9．cast n.演员阵容，全体演员 vt.投射(光或影) 10．visualise vt.设想，想象 11．generate vt.产生，创造 12．version n.版本 13．category n.类别，种类，范畴 14．proof n.证明 ◎拓展单词 15．expect vi.&vt.期待；期望；指望→expectation n.期待，预期，预料→expected adj.预期的；预料的→unexpected adj.意外的；出乎预料的 16．pessimistic adj.悲观的→pessimism n.悲观，悲观情绪 17．novel n.(长篇)小说 adj.新颖的→novelist n.小说家 18．adapt vi.&vt.使适应；改编→adaptation n.改编版；适应 19．appropriate adj.恰当的；合适的→appropriately adv.适当地；合适地 20．definite adj.清楚的，明确的→definitely adv.清楚地；明确地，肯定地 21．technique n.技巧，技术；手法→technical adj.技术上的→technically adv.技术上；专门地 Ⅱ.重点短语 1．be made from 由……制成 2．as well as 也；和……一样 3．be close to 接近，靠近 4．leave out 遗漏，省去；不考虑 5．fall down 跌倒；失败；倒塌 6．have an impact on 对……有影响 7．be involved in 包括……中，被卷入……中；涉及到…… 8．adapt to 适应 9．make sure 确保 10．the majority of 大多数 Ⅲ.句式语境 1．部分否定 Although highly regarded books do not always make good films，it is safe to say that great films may be made from not particularly good books. 尽管高质量的书并不总是能拍出好看的电影，优秀的电影也可能来自不是那么好的书，说的倒是没错。 2．too...to...
