问题     The United States is well-known for its network of major highways designed to help a driver get from one place to another in the shortest possible time. 【51】these wide modern roads are generally smooth and well maintained, with【52】sharp curves and many straight sections, a direct route is not always the most【53】one. Large highways often pass by scenic areas and interesting small towns.  Furthermore, these highways generally【54】large urban centers which means that they become crowded with heavy traffic during rush hours,【55】the "fast, direct" way becomes a very slow route.
    However, there is almost always another route to take【56】you are not in a hurry. Not far from the【57】new "super highways", there are often older, less heavily traveled roads which go through the countryside. 【58】of these are good two-lane roads; others are uneven roads curling through the country.  These secondary routes may go up steep slopes, along high cliffs, or down frightening hillsides to towns【59】in deep valleys.  Through these less direct routes, longer and slower, they generally go to place where the air is clean and the scenery is beautiful, and the driver may have a【60】to get a fresh, clean view of the world.  [br]
选项 A、when
B、for
C、but
D、that
答案 A
解析 从语法关系看，此句是一个非限定性定语从句，修饰前边的rush hours，意思在交通高峰期间，这条快速直达的公路变成了一条缓慢的线路。四个选项中，A项when和D项that均可引导定语从句，但是that不能引导非限定性定语从句，而且在从句中它必须作主语或宾语。因此，这里不能用that，只能用when，意思是“这时”。
