參考答案及詳解1. A) 此空四個選項都是從屬連詞，但是它們的屬性是不同的，例如：although是表示轉折關係的;since，because，therefore是表示原因關係的。通過閱讀此空所在句得知大概句義爲：“儘管這些寬闊的現代化公路通常很平坦且維護良好，轉彎也很少，但是一直保持筆直的公路不總是令人賞心悅目”。根據語義線索和語法線索可知此空應填表示轉折關係的選項A。
2. C) 根據詞彙線索和詞義搭配可知，stable，splendid和complicated一般不能用來修飾roads。
3. B) 根據語義線索可推斷此空正確答案爲選項B few。
4. C) 根據上下文可推測出如果高速公路總是保持筆直，對於駕駛者來說是非常枯燥的，因此本空的正確答案爲C enjoyable。
5. D) 介詞by能和動詞pass搭配，意爲“經過，掠過”。
6. B) 本句中的聯繫副詞Furthermore說明本句是對上一句的進一步補充和信息的'增加，由此可推測本句句義爲高速公路不僅經過風景區鄉村，通常還“將龐大的都市中心區連接起來”。故正確答案爲B。
7. D) “交通擁擠”用heavy 和traffic搭配。
8. A) 通過分析可知，這裏使用的是一個非限定性定語從句，四個選項中只有A when 具備此語法功能
9. B) 根據上下句關係可推斷此句爲條件句，故選項B爲正確答案。
10. A) 根據主句中的“older ... roads”可推斷此空需要填一個比較意義的副詞，以構成對比關係，故選項A relatively“相應地，相對地”爲正確答案。其他三詞詞義分別爲：regularly“有規律地，定期地”;respectively“各自地”;reasonably“有理由地”。
11. B) 根據此空前後詞及結構可斷定此空應使用比較級，故可排除A和D。另外根據上下文可推測此空應爲less，因爲“more heavily嗎traveled”意爲“車輛擁擠的”公路，與常識不符。
12. D) 從下文的others可知此空正確答案爲D some。
13. B) 根據上文的slopes和下文的hillsides就可以斷定這裏需要一個表示路況不好的詞，選項Arocks意義不符，故只有B cliffs “懸崖” 爲正確答案。
14. A) 根據題目和選項可斷定此空應爲towns的後置定語，由此可猜測句義爲“位於深谷中的城鎮”，“位於”lie是不及物動詞，不能以過去分詞的形式出現作名詞的後置修飾語，故正確答案爲lie的現在分詞形式lying。
15. D) 定語從句修飾places用where來引導。
