百科知识之交通工具演变过程
早些时候，人类还没有“交通工具”这一代名词，那时，人们主要是靠步行来相互走访联系的。
然后人类就驯服一些动物如马、驴子等作为乘坐工具或乘坐工具的动力（如：马车），与此同时，轿子和以风作为动力的帆船也作为一种交通工具与畜力交通工具长期并存。以人力、畜力和风力作为动力的交通工具占据了人类历史的绝大部分时间。交通工具的另一次巨大飞跃开始于工业革命。18，19世纪人类进入了“科学的世纪”，詹姆斯·瓦特发明的现代蒸汽机的成型，标志着人类开类经入了新的交通发展阶段，蒸汽机车，汽船发明，极大地“缩短”了区域之间的距离。
现代交通工具已由牲畜拖拉演变为汽车、火车、轮船、飞机，效率大大提高，缩短了国与国之间的距离。但同时， 如人们所说，万物都有其两面性。交通工具的发达，给人类带来了方面和快捷，却没有给人类带来幸福。

重点探究
Cars
The modern car has changed life a great deal. Before the invention of the car, people had to travel by rail, on horseback or by horse-drawn carriage, or on foot. Using horses for travel was slow, and of course walking was even slower. Cars allow people to travel long distances quickly,in comfort and convenience.
马车
The car also solved an enormous problem caused by using horses for transport in cities: manure! There were so many horses in large cities that it was almost impossible to get rid of the manure. Modern people are used to the idea that cars cause pollution, but the first cars actually made cities cleaner!

Learning to learn
When you do a listening or reading exercise, you should read the instructions carefully. Then you can focus your attention just on the information you need. You don’t have to understand every word.
4. Read the email and find three examples that show life was harder in the past than it is today.
FROM: Gran
TO: Christine
SUBJECT: The lives of children in Victorian Britain
Dear Christine,
You asked me for help about your school project – the lives of children in Victorian Britain. I was also interested. I searched online and found out the following.
In Victorian Britain, thousands of people came to the cities to work in the factories.Instead of the green,open countryside, people lived in very small houses,very close to each other, with no space for children to play.Families in those days were quite big.
FROM: Gran
TO: Christine
SUBJECT: The lives of children in Victorian Britain
Often,there were four or five children in one family, and they all had to sleep in houses of just two rooms. Sometimes, a whole street had to share one outside toilet. Can you imagine that
Most of the big cities were dirty and unhealthy. The pollution from factories filled the air. People put their rubbish outside in the streets. As a result, there were many illnesses.
FROM: Gran
TO: Christine
SUBJECT: The lives of children in Victorian Britain
And life was harder for children in those times.They didn’t always go to school, because they had to work instead. Many children started work in factories when they were only four or five years old. They worked twelve hours a day in dangerous jobs for very little money. Many were hurt in accidents with machines.
I hope this is helpful. Write to me if you need more information.
With love,
Gran
