[00:06.23]Lesson 29
[00:08.67]1.2 Before the invention of trains and cars,
[00:14.71]people could use three basic types
[00:16.95]of transportation.
[00:18.92]They could travel on horseback
[00:21.09]or ride on the back of another animal
[00:23.76]such as a donkey²,
[00:25.14]a camel etc,
[00:27.91]or they could ride in a cart³ pulled by a horse.
[00:31.85]For a person who could not afford a horse
[00:34.35]or a donkey,
[00:35.73]the only choice waste travel on foot,that is,
[00:40.25]to walk.
[00:42.44]In ancient times,rivers were difficult to cross
[00:46.94]People could not cross wide rivers
[00:49.50]unless they had some sort of boat.
[00:52.91]However,if a river was not too wide,
[00:56.67]people could build a bridge across it.
[00:59.62]In places where the river was not very deep,
[01:02.98]people could walk across.
[01:05.94]In the past,
[01:07.70]roads were very different from today.
[01:10.97]They were just dirt tracks⁴.
[01:13.20]So,in the winter the rain
[01:16.18]and sonw made these tracks full of mud⁵.
[01:19.82]Sometimes,the roads were so bad
[01:23.17]that heavy cars could not pass.
[01:26.36]Even in good weather,
[01:27.99]travelling by road was slow.
[01:30.73]It could take many days
[01:32.38]to travel a few hundred kilometers.
