8、The great advantage of the electric train over the steam train, I think, is that it does not smell．When a person is in a  1  drawn by a steam locomotive（机车），one always has the  2  smell of burning coal around one. If one opens the window to look out at the   3  and to get some fresh air, one is  4  with little bits of coal-ash which get into one’s hair and eyes, and soon force one to shut the window again and withdraw（退缩）into the  5  atmosphere of one’s compartment（车厢）. In a tunnel,  6  distress reaches a peak, for there the smoke is forced into a  7  area, from which it escapes into the train itself through any small cracks（缝隙）it may

 8 . In a long tunnel, the  9  grows worse and worse, while one’s eyes smart（刺痛）and the electric light in the carriage grows no longer  10  , hidden behind the smoke.

       With an electric locomotive, on the other hand, one can enjoy the view and the fresh air without inconvenience. I really think that one gets part of the extra  11  out of traveling through the Alps or Tyrol by train for the simple  12  that the trains there are  13  operated, so that the traveler who  14  become used to having his air dirtied by  15  and considers such a condition as  16 , believes that there is something extra-special about the Tyrolese air. Of course,  17  air is purer and fresher than the air of the plains,  18  the smoke of a steam train  19  not allow this condition to  20.
