问题 The main point of the passage is ______.
What does the author say about straight, horizontal bars painted across roads?

选项 A、They are falling out of use in the United States.
B、They tend to be ignored by drivers in a short period of time.
C、They are applicable only on broad roads.
D、They cannot be applied successfully to traffic circles.

答案B

解析本题考查对倒数第2段的准确理解。文章说：“最初能让驾驶员减速一半”，“但数月后驾驶员便恢复到原来的速度”。也就是说，垂直横线只能在短时期内影响到驾驶员的行驶速度，过一段时间就不起作用了，因此B项是本题的答案。
