（24）On the Highway 在公路上

    The interstate highway system makes long-distance travel by car fast and convenient. Interstate highways are clearly marked with numbers： odd¹ numbers mark north and south routes and even numbers mark east and west routes. Such toll² roads as turnpikes, thruways and parkways are part of the interstate system. The speed limit on all highways is 55 miles per hour unless otherwise posted. Remember that 1 mile=1.6 kilometers.
