    參考答案及詳解
    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(guò)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(yǔ)義線索和語(yǔ)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(lái)修飾roads。
    3. B) 根據(jù)語(yǔ)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(lái)說(shuō)是非?？菰锏模虼吮究盏恼_答案為C enjoyable。
    5. D) 介詞by能和動(dòng)詞pass搭配，意為“經(jīng)過(guò)，掠過(guò)”。
    6. B) 本句中的聯(lián)系副詞Furthermore說(shuō)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(guò)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(lái)”。故正確答案為B。
    7. D) “交通擁擠”用heavy 和traffic搭配。
    8. A) 通過(guò)分析可知，這里使用的是一個(gè)非限定性定語(yǔ)從句，四個(gè)選項(xiàng)中只有A when 具備此語(yǔ)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)?ldquo;more heavily traveled”意為“車(chē)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(yǔ)，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(guò)去分詞的形式出現(xiàn)作名的后置修飾語(yǔ)，故正確答案為lie的現(xiàn)在分詞形式lying。
    15. D) 定語(yǔ)從句修飾places用where來(lái)引導(dǎo)。
