（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： odd numbers mark north and south routes and even numbers mark east and west routes. Such toll 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.
