　　答案與解析：

　　1. A) 此空四個(gè)選項(xiàng)都是從屬連詞，但是它們的屬性是不同的，例如：although是表示轉(zhuǎn)折關(guān)系的；since，because，therefore是表示原因關(guān)系的。通過閱讀此空所在句得知大概句義為：盡管這些寬闊的現(xiàn)代化公路通常很平坦且維護(hù)良好，轉(zhuǎn)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(jù)語義線索和語法線索可知此空應(yīng)填表示轉(zhuǎn)折關(guān)系的選項(xiàng)A。

　　2. C) 根據(jù)詞匯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(jù)語義線索可推斷此空正確答案為選項(xiàng)B few。

　　4. C) 根據(jù)上下文可推測(cè)出如果高速公路總是保持筆直，對(duì)于駕駛者來說是非常枯燥的，因此本空的正確答案為C enjoyable。

　　5. D) 介詞by能和動(dòng)詞pass搭配，意為經(jīng)過，掠過。

　　6. B) 本句中的聯(lián)系副詞Furthermore說明本句是對(duì)上一句的進(jìn)一步補(bǔ)充和信息的增加，由此可推測(cè)本句句義為高速公路不僅經(jīng)過風(fēng)景區(qū)和鄉(xiāng)村，通常還將龐大的都市中心區(qū)連接起來。故正確答案為B。

　　7. D) 交通擁擠用heavy 和traffic搭配。

　　8. A)通過分析可知，這里使用的是一個(gè)非限定性定語從句，四個(gè)選項(xiàng)中只有A when 具備此語法功能。

　　9. B)根據(jù)上下句關(guān)系可推斷此句為條件句，故選項(xiàng)B為正確答案。

　　10. A)根據(jù)主句中的older ... roads可推斷此空需要填一個(gè)比較意義的副詞，以構(gòu)成對(duì)比關(guān)系，故選項(xiàng)A relatively相應(yīng)地，相對(duì)地為正確答案。其他三詞詞義分別為：regularly有規(guī)律地，定期地；respectively各自地；reasonably有理由地。

　　11. B)根據(jù)此空前后詞及結(jié)構(gòu)可斷定此空應(yīng)使用比較級(jí)，故可排除A和D。另外根據(jù)上下文可推測(cè)此空應(yīng)為less，因?yàn)閙ore heavily traveled意為車輛擁擠的公路，與常識(shí)不符。

　　12. D)從下文的others可知此空正確答案為D some。

　　13. B)根據(jù)上文的slopes和下文的hillsides就可以斷定這里需要一個(gè)表示路況不好的詞，選項(xiàng)A rocks意義不符，故只有B cliffs 懸崖為正確答案。

　　14. A)根據(jù)題目和選項(xiàng)可斷定此空應(yīng)為towns的后置定語，由此可猜測(cè)句義為位于深谷中的城鎮(zhèn)，位于lie是不及物動(dòng)詞，不能以過去分詞的形式出現(xiàn)作名詞的后置修飾語，故正確答案為lie的現(xiàn)在分詞形式lying。

　　15. D)定語從句修飾places用where來引導(dǎo)。
