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。

2Have you ever wondered what our future is like?Practically all people _1_ a desire to predict their future _2_.Most people seem inclined to _3_ this task using causal reasoning.First we _4_ recognize that future circumstances are _5_ caused or conditioned by present ones.We learn that getting an education will _6_ how much money we earn later and that swimming beyond the reef may bring an unhappy _7_ with a shark.Second,people also learn that such _8_ of cause and effect are probabilistic(可能的) in nature.That is,the effects occur more often when the causes occur than when the causes are _9_, but not always.Thus,students learn that studying hard _10_ good grades in most instances,but not every time.Science makes these concepts of causality and probability more _11_ and provides techniques for dealing _12_ then more accurately than does causal human inquiry.In looking at ordinary human inquiry,we need to _13_ between prediction and understanding.Often,even if we don't understand why,we are willing to act _14_ the basis of a demonstrated predictive ability.Whatever the primitive drives _15_ motivate human beings,satisfying them depends heavily on the ability to _16_ future circumstances.The attempt to predict is often played in a _17_ of knowledge and understanding.If you can understand why certain regular patterns _18_,you can predict better than if you simply observe those patterns.Thus,human inquiry aims _19_ answering both "what" and "why" question,and we pursue these _20_ by observing and figuring out.1.
