Exercise 36

Underline the four change-of-direction signals in the following paragraph.
In some ways, train travel is superior to air travel. People always marvel at the speed with which airplanes can zip from one end of the country to another. Trains, on the other hand, definitely take longer. But sometimes longer can be better. Traveling across the country by train allows you to experience the trip more completely. You get to see the cities and towns, mountains and prairies that too often pass by unnoticed when you fly. Another advantage of train travel is comfort. Traveling by plane means wedging yourself into a narrow seat with your knees bumping the back of the seat in front of you and, if you're lucky, being handed a "snack" consist­ing of a bag of pretzels. I n contrast, the seats on most trains are spacious and comfortable, permitting even the longest-legged traveler to stretch out and watch the scenery just outside the window. And when train travelers grow hungry, they can get up and stroll to the dining car, where they can order anything from a simple snack to a full meal. There's no question that train travel is definitely slow and old-fashioned compared with air travel. However, in many ways it is much more civilized.
