【答案及详解】

答案：DCBAB

贝克尔和哈特曼报道说，“睡眠少的人”在未进入少年期之前，其正常睡眠

时间大致与所需要的时间差不多。但到了15岁左右，由于学校、工作或其它活

动的地压力，他们就故意地减少了夜间睡眠的时间。这些人持有这样的观点：夜

间睡眠是一件令人讨厌的事情，打断了日常事务。

总的说来，这些“睡眠少的人”表现得雄心勃勃、积极活跃、精力充沛、无

意识乐观豁

达、立场坚定，对自己职业的选择胸有成竹。他们往往同时从事几项工作，

或者一边上学读书，一边从事专职或兼职工作。其中许多人有强烈愿望，想在朋

友和熟人面前表现得“正常”或“合群”。

当让他们回忆梦境时，“睡眠少的人”回忆不起什么来。更有甚者，他们似

乎情愿什么都记不住。类似的情况是他们通常处理心理问题的方式：不承认问题

的存在，希望只要忙忙碌碌，麻烦总会过去的。

“睡眠少的人”的睡眠模式与被划入疯子之类精神病患者的睡眠模式十分

相似，只不过没有那么严重而已。

“睡眠多的人”情形则大不相同。贝克尔和哈特曼报道说，这些年轻人从小

的，有抱负的睡眠就一直很长。他们好像注重睡眠，不让睡眠受打搅。偶尔没有

所需的9个小时夜间卧床休息，他们便会十分不安。他们比“睡眠少的人”要更

能回忆得起梦的内容。许多“睡眠多的人”腼腆、焦躁、内向、压抑、消极和稍

微有点儿沮丧，尤其在社交场合缺乏自信。好几个人坦言，睡眠是摆脱每天烦恼

的一种方式。

答案：CCCDA

1Co事实细节题。第一段提到了影响视幅的因素：不同的人，不同的阅读

目的，对材料的熟悉程度，光线，疲劳。C“一组词的长度”不是能影响视幅的

因素，是本题的答案。2Co观点态度题。作者在第二段第二句提到，眼睛训练

课程只注重了阅读的视觉因素。倒数第二句书哦，阅读要求具备理解单词间关系

的能力。因此选项C“阅读需要大脑的深度参与”正确。作者没有否定阅读的视

觉因素的必要性，但是也没有说读者应该练习拓宽视幅，加快阅读速度。所以

AB两项都不正确。作者没有对大脑和眼睛在阅读过程中的重要性进行对比，所

以不选D

3Co作者在这句话中先是肯定了那些阅读练习提高看单词的能力，然后提

出了有效阅读概念。后面句中还指出，有效阅读需要的是理解单词间的联系的能

力。所以作者的意思应该是那些（训练眼睛的）阅读练习对与有效的阅读无益。B

与文章相反。D句是蕴涵其中一个意思，却不是作者想表达的方向。

4Do第二段最后一句说，眼睛训练对于帮助读者阅读连贯文章无益，所以

D是错的，是本题答案。

5Ao参考前面的结构剖析，作者写本文的主要目的是对那些只关注阅读的

视觉因素的阅读能力课程进行批判，所以答案应该是Ao

【答案及详解】

L选B）。此处应填形容词。原文意思为“会计部门.•・计算报酬”，选项中

8

的形容词responsible”负责任的”，useful”有用的”，indirect"间接的”，

successful“成功的"，其中indirect不能与for连用,排除;乘)余几项中只有

B)responsible意义符合原句，其他均不符合，故排除。

2,选0)。此处应填动词原形。本文主题就是采用一种新的工资和薪水制度

时需要注意的问题，选项中的动词原形有compare“比较”，find“找到”，

adopt“采纳”，分别带入原文，只有adopt最符合原文意思，故选0).

3.选H)。此处应填名词。从原文看，and连接并列结构，所以要填的词应与

and后面的ways意思一致，选项中的名词只有mathod=ways,故选H)method。

4.选D。此处应填形容词。上文说新的工资制度需要一套决定工作评估和

衡量雇员表现的方法，说的是制度“是否有用”的问题。这句说的时新的工资制
