　　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。
