阅读完形

完形填空(一)宏观上处理好篇章与空格之间的关系完形填空的测试目的是测试学生运用语言的综合能力。

完形填空的考试重点是上下文的联系和短语结构的搭配关系。

由于考试时间紧，许多考生在回答这部分题的时候，往往不顾整个篇章的结构、大意或文体，一开始就把注意力放在空格选项上，孤立地研究单个选项，这就脱离了文章整体，答题的准确率也会大受影响。

因此，要做好这部分试题考生首先必须大体理解篇章的主要内容、逻辑关系，从而判断出作者的意图及归纳或演绎的思路；另外，考生在答题之前，还要对文章的文体有所了解，这有利于考生根据不同的文体对不同的或相近的选项做出正确的选择。

如文学材料、科普文章、新闻报道等由于文体上的不同，它们在用词和句子结构上都有所不同。

请看下面例子：Vitamins are organic compounds necessary in small amounts in the diet for the normal growth and maintenance of life of animals, including man. They do not provide energy, ___1___ do they construct or build any part of the body. They are needed for ___2___ foods into energy and body maintenance. There are thirteen or more of them, and if ___3___ is missing, a deficiency disease becomes ___4___.1. A. either B. so C. nor D. never2. A. shifting B. transferring C. altering D. transforming3. A. any B. some C. anything D. something4. A. serious B. apparent C. severe D. fatal通读全文后可知，这是一篇有关科普知识的短文，一般来说科普知识文章以客观陈述为突出特点，用词比较正式，句子结构比较严密，因此在选择时要在宏观上考虑到这些因素。

比如第四空，从科学常识可知，缺乏任何一种维生素都不至于使疾病严重(serious)、致命(fatal)，故应排除选项A和D。

severe（严厉的）不能用来修饰疾病。

因此，选B apparent 既合乎句意，搭配又得当。

另外，完形填空的空格没有任何一个是孤立地存在的，必须把它们放在文章的语言环境中进行逐个推敲，同时利用自己对各种材料描写、陈述内容的了解，作出正确选择。

PART ⅠDecide which of the choices given below would correctly complete the passage if inserted in the corresponding blanks. Mark the correct choice for each blank on your ANSWER SHEET.

A. lying B. laying C. laid D. lied15. A. there B. when C. which D. where参考答案及详解1. A) 此空四个选项都是从属连词，但是它们的属性是不同的，例如：although是表示转折关系的；since，because，therefore是表示原因关系的。

通过阅读此空所在句得知大概句义为：“尽管这些宽阔的现代化公路通常很平坦且维护良好，转弯也很少，但是一直保持笔直的公路不总是令人赏心悦目”。

根据语义线索和语法线索可知此空应填表示转折关系的选项A。

2. C) 根据词汇线索和词义搭配可知，stable，splendid和complicated一般不能用来修饰roads。

3. B)根据语义线索可推断此空正确答案为选项B few。

4. C) 根据上下文可推测出如果高速公路总是保持笔直，对于驾驶者来说是非常枯燥的，因此本空的正确答案为C enjoyable。

5. D) 介词by能和动词pass搭配，意为“经过，掠过”。

6. B) 本句中的联系副词Furthermore说明本句是对上一句的进一步补充和信息的增加，由此可推测本句句义为高速公路不仅经过风景区和乡村，通常还“将庞大的都市中心区连接起来”。

故正确答案为B。

7. D) “交通拥挤”用heavy 和traffic搭配。

8. A)通过分析可知，这里使用的是一个非限定性定语从句，四个选项中只有A when 具备此语法功能。

9. B)根据上下句关系可推断此句为条件句，故选项B为正确答案。

10. A)根据主句中的“older ... roads”可推断此空需要填一个比较意义的副词，以构成对比关系，故选项A relatively“相应地，相对地”为正确答案。

其他三词词义分别为：regularly“有规律地，定期地”；respectively“各自地”；reasonably“有理由地”。

11. B)根据此空前后词及结构可断定此空应使用比较级，故可排除A和D。

另外根据上下文可推测此空应为less，因为“more heavily traveled”意为“车辆拥挤的”公路，与常识不符。

12. D)从下文的others可知此空正确答案为D some。

13. B)根据上文的slopes和下文的hillsides就可以断定这里需要一个表示路况不好的词，选项A rocks意义不符，故只有B cliffs “悬崖” 为正确答案。

14. A)根据题目和选项可断定此空应为towns的后置定语，由此可猜测句义为“位于深谷中的城镇”，“位于”lie是不及物动词，不能以过去分词的形式出现作名词的后置修饰语，故正确答案为lie的现在分词形式lying。

15. D)定语从句修饰places用where来引导。

TEXT ABefore the mid1860’s, the impact of the railroads in the Un ited States was limited, in the sense that the tracks ended at this Missouri River, approximately the center of the country. At the point the trains turned their freight, mail, and passengers over to steamboats, wagons, and stagecoaches. This meant that wagon freighting, stage coaching, and steam boating did not cometo an end when the first train appeared; rather they became supplements or feeders. Each new “end of track” became a center for animal drawn or waterborne transportation. The major effect of the railroad was to shorten the distance that had to be covered by the older, slower, and more costly means. Wagon freighters continued operating throughout the 1870’s and 1880’s and into the 1890’s.Although over constantly shrinking routes, and coaches and wagons continued to crisscross the West wherever the rails had not yet been laid. The beginning of a major change was foreshadowed in the later 1860’s, when the Union Pacific Railroad at last began to build westward from the Central Plains city of Omaha to meet the Central Pacific Railroad advancing eastward from California through the formidable barrier of the Sierra Nevada. Although President Abraham Lincoln signed the original Pacific Railroad bill in 1862 and a revised, financially much more generous version in 1864, little construction was completed until 1865 on the Central Pacific and 1866 on the Union Pacific. The primary reason was skepticism that a Railroad built through so challenging and thinly settled a stretch of desert, mountain, and semiarid plain could pay a profit. In the words of an economist, this was a case of “premature enterprise”, where not only the cost of construction but also the very high risk deterred private investment. In discussing the Pacific Railroad bill, the chair of the congressional committee bluntly stated that without government subsidy no one would undertake so unpromising a venture; yet it was a national necessity to link East and West together.16. The author refers to the impact of railroads before the late 1860’s as “limited” because ____.A. the track did not take the direct route from one city to the nextB. passengers and freight had to transfer to other modes of transportation to reach western destinationsC. passengers preferred stagecoachesD. railroad travel was quite expensive17. What can be inferred about coaches and wagon freighters as the railroad expanded?A. They developed competing routes.B. Their drivers refused to work for the railroads.C. They began to specialize in private investment.D. There were insufficient numbers of trained people to operate them.18. Why does the author mention the Sierra Nevada in line 17?A. To argue that a more direct route to the West could have been taken.B. To identify a historically significant mountain range in the West.C. To point out the location of a serious train accident.D. To give an example of an obstacle faced by the central pacific.19. The word “subsidy” in line 27 is closest in meaning to_____.A. persuasionB. financingC. explanationD. penalty答案和解析：16. B)根据文章前五句可知，在十九世纪六十年代晚期前铁路在美国的影响是有限的“limited”，当时铁路只从美国东部修到了美国中部，运到美国西部地区的货物只有在铁路的尽头“end of track”改用其他的运输方式，比如：汽船、马车等，它们的运输效率可想而知。
