How many ways can you think of to use wheels
How can you get to the moon
Hello，I'm Jeremy. I'm from the U．S. This is my report on transportation.
This world is always moving. Everything seems to have wheels，engines or wings.
课文呈现
What’s your favourite
type of transportation.
新课讲解
Everything seems to be getting faster，too. Long ago，horses pulled carts，but now we have engines on everything，even on bicycles and skateboards!
Where did it begin
Well，in the 1700s people invented the steam engine. That was the beginning of trains. Then steam was able to power boats and cars. Boats have been around for thousands of years. Now with engines，they can go very fast. The first car appeared about two hundred years ago，and now the roads are full of cars. All of these cars make the U．S. a nation on wheels.
新课讲解
Transportation is not just on the ground or water. Over 100 years ago，people began to make flying machines. Today we travel a lot by airplane.
Now people can even travel to space in spaceships. Can you imagine future transportation
My favourite type of transportation is the bicycle. I like to go everywhere by bike in my city. It's good for my health and for the environment.
It’s fun to ride a bike.

新课讲解
Read the passage and label the bicycle.
Bicycle means “two wheels”. The first bicycle was probably created in Germany in 1816.It was heavy and had wooden wheels. At first, the bicycle had two wheels but no pedals. People pushed it along with their feet. In 1838，a man in the U．K. invented pedals. The modern bicycle was invented in 1876 in England. By 1900，bicycles had tyres filled with air.Air filled tyres made bicycles more

Language point 1
This is my report on transportation.
这是我关于交通的报告。
本句中的on意为“关于”。 on与about作介词时,都意为“关于”,但用法不同。on用于严肃的或学术性的内容,较为正式。about表示内容较普通,不太正式。
e.g. This book is on science.这本书是关于科学方面的。
It’s a story about Lei Feng.那是一个关于雷锋的故事。
新课讲解
Language point 2
Everything seems to have wheels, engines or wings.一切似乎有车轮，发动机或翅膀。
seem意为“似乎;好像”。 seem 后接动词不定式,构成 seem to do sth.结构,意为“似乎/好像要做某事”。
e.g. The math problem seems to be difficult.
那道数学题好像很难。
新课讲解
Language point 3
Then steam was able to power boats and cars.蒸汽能够驱动船和汽车。
be able to意为“能;会;能够”,后接动词原形。
【辨析】be able to,can
be able to强调具体事件中有能力,指“经过努力而成功地做某事”,可用于各种时态。can只是一般性的能力,指“有能力做某事”,只用于一般现在时和一般过去时两种时态。
e.g. He will be able to drive next year.明年他就能开车了。
She can sing the song in English.她能用英语唱这首歌。
新课讲解
Language point 4
Boats have been around for thousands of years. 船已经存在数千年了。
◆“for+ 一段时间”表示动作从过去开始一直持续到现在,常用于现在完成时的句子中。 现在完成时的句子结构为“主语+have/has+过去分词+其他”。
e.g. The movie has been on for ten minutes.
电影已经开始十分钟了。
新课讲解
◆thousands of 意为“成千上万的,数以千计的”。当用hundred,thousand,million,billion等词表示一个不具体的数字时,这些词用复数形式,而且常与介词of 连用来修饰名词。
e.g.Thousands of visitors come to Beijing during May Day holidays every year.
每年五一假期成千上万名游客来北京。
