答案与解析
51.B。题干:现在,科普的计算机写出的作品与德国著名作曲家J.S.巴赫写的作品很相似,很少有人能__________ 出其中的不同。本题考查句意和名词。四个选项分别代入后,tell the difference为固定搭配意为“分辨不同”,代入后比较符合原文的语境,故B为正确答案。
52.A。题干:但是他__________ 创作出新的旋律,于是他编写了一个计算机软件来帮他编曲。本题考查固定搭配。Have trouble doing sth意为“做……有麻烦”,have some time/fear to do sth意为“做某事有时间/担心去”,have pleasure doing sth意为“做……有乐趣”,四 个选项分别代入后,只有have trouble比较符合语境,故A为正确答案。
53.D。题干:最开始的时候,软件写出的乐曲并不__________ 去听。本题考查形容词和句意。根据后一句,Cope是怎么做的呢?他开始重新考虑人们作曲的方式,由此可以知道该句谈论的是最初遇到的问题,四个选项分别代入后,easy比较符合语境,表示音乐起初听起来不动听。故D为正确答案。
54.D。题干:他意识到作曲家的大脑__________ 就像一个大数据库。本题考查句意和动词。四个选项分别代入,“工作起来像个大数据”库比较符合语境,其他几个代入后都不合逻辑,故D是正确答案。
55.D。题干:然后他们会__________ 他们不喜欢的音乐。本题考查句意和固定搭配。take in意为“吸收”,take with意为“带上”,take out意为“拿出,取出”,不喜欢的音乐应该将其拿出,故D是正确答案。
56.B。题干:最后再根据__________ 创作出新的旋律。本题考查固定搭配和上下文语义。根据原文的语境,他们先是吸收他们听过的所有音乐,然后去除他们不喜欢的,所以最后应该是根据留下的音乐来创作出新的旋律,因此B为正确选项。
57.B。题干:科普根据现有的音乐建立了__________ 数据库。本题考查形容词和句意。四个选项分别代入,根据前后的句子可以发现huge比较符合语境。因此B为正确选项。
58.C。题干:科普的软件将这些数据进行分析:首先它将音乐__________ 小的片段,从中找出固定模式。本题考查上下文语义和固定搭配。四个选项都可以跟空格后的down形成固定搭配,其中cut down意为“砍到”,drop down意为“下降”,break down意为“打破,粉碎;出故障”,turn down意为“降低音量,拒绝”,从原句的“smaller pieces”可推断出C为正确答案。
59.D。题干:然后将__________ 组合成新的模式。本题考查形容词和句意。根据前一句,科普的软件将这些数据进行分析:首先它将音乐拆解成小的片段,从中找出固定模式。由此可知是将这些片段进行组合,故D为正确选项。
60.D。题干:他进一步完善他的软件,不久它就能够__________ 更复杂的音乐了。本题考查动词和上下文语义。根据上下文,他进一步改善软件就是希望软件能帮助其分析和创作出更复杂的音乐,由此D选项为正确答案。
61.B。题干:几年后,科普的软件“艾米”已经能够帮助他创作歌剧了。__________ 需要作曲家和艾米共同配合。本题考查名词词义和句意。四个选项分别代入,显然是在软件创作音乐过程中需要作曲家和艾米共同配合,故B为正确选项。
62.A。题干:科普聆听艾米写出的音乐片段,使用了他认为好的__________ 。本题考查代词。根据原文语境,科普聆听艾米所创作的音乐片段,然后选取了他认为好的片段,因而用ones来指代所创作的音乐片段,故A为正确选项。
63.C。题干:有了艾米的帮助,科普只用了两个星期就完成了这部歌剧,叫作《摇篮坠落》,该部歌剧是巨大的__________ 。本题考查句意和名词。从空格前的修饰语great来看,great success比较符合语境,故C为正确选项。
64.B。题干:科普也得到了他有生以来最高的评价,但是没有人知道他究竟是——创作出这部歌剧的。本题考查状语从句引导词。四个选项分别代入,没有人知道他是用软件创作出来的,所以how比较符合原文的语境,故B为正确答案。
65.A。题干:普现在依然会给艾米反馈,告诉她自己哪些音乐是他喜欢的,哪些是不喜欢的,__________ 现在大部分的工作是由艾米来完成的。本题考查上下文逻辑关系。原文中空格前后为转折关系,所以本题选A。
