1.How many ways can you think of to use wheels
2.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.
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
What's your favourite type of transportation.
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.
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.
Let's Do It!

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
comfortable to ride. Today's bicycles look the same as bicycles from the 1900s, but they are lighter. This is because they all have hollow frames.

about
表示的内容较普通, 不太正式

那是一个关于雷锋的故事。
2. The world is always moving.
be always doing sth “总是或一致做某事”, 现在进行时与always连用, 表示一个经常重复的动作或状态。常用来表达说话人的某种感情, 如：赞叹、埋怨、厌烦等。
He is always talking.
他老是说话。

3. Everything seems to be getting faster, too
主语+seem to be +表语

4. Long ago, horses pulled carts…
pull作及物动词, 意为“拉, 拖”, 反义词为push

他拉开了门。
相关短语：
pull down“推翻；摧毁” pull out of “拔掉；取出”
They pulled down many old houses last year.
去年她们拆了很多旧房子。
5. Then steam was able to power boats and cars.
be able to表示“能；能够”, 后接动词原形
辨析：can & be able to
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, 不与can连用
can
只是一般性的能力, 指“有能力做某事”
只有现在式和过去式两种形式
6.Boats have been around for thousands of years.
(1)“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”。

电影已经开始十分钟了。
(3)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。
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
7.All of these cars make the U.S.a nation on wheels.
“make sb./sth.+n.”意为“使……成为……”, 在本句中, on wheels是后置定语, 修饰a nation。

(2)imagine后接动名词或名词复合结构作宾语。

(4)imagine后接疑问词引导的宾语从句或“疑问词+不定式”结构
