①take +a/an/the+交通工具
（放句中）特殊的是自行
车不能用take
②by+交通工具（放句尾）
③in/on+a/an/the+交通工具
（放句尾）
例如：我每天乘坐公共汽

bike
drive a car 也可以是take a
car
He rides a bike to school.
He goes to school by bike.
He rides to school.可以省略
bike
He drives to school.可以省略
car
ride除了动词骑之外，还有名词一段路程的意思
go for a ride去兜风
give me a ride 让我搭个便车
get sb. a ride打顺车

The bus ride takes me about
20 minutes. 公共汽车之旅花费我20分钟。
3.步行到学校

on foot
on foot放到句末
4.对交通方式提问用how
如：I go to school by bike.
对by bike提问用 How do
you go to school?
5.三个到达：get to/arrive in/at
/reach
只有reach后面不加介词
arrive in+大地点
arrive at+小地点
6.train ①火车②训练
7.take a walk=have a walk 散步go out for a walk出去散步
8.What about =how about
doing sth？做某事怎么样呢？因为about是介词，后面用动词ing
9.hundred百 thousand 千
million 百万
当前面加数字时它们都不加s
当前面没有数字，后面加of 时他们加s
如：hundreds of 成百上千的
thousands of成千上万的10.本单元有一个最重要的句型：
It takes sb.+时间+to do sth.
sb.用宾格 take译为花费
例如:
It takes me ten minutes to go
to school on foot.
翻译的时候从后往前面翻译:步行去学校花费我十分钟
对以上句子中的ten minutes 提问是本单元的第二个重点句型：
How long does it take you to
go to school on foot?译为：步行到学校需要花费你多久？
对这个句型的回答一般用
How long，但是因为在原句型中时间前面没有for,所以回答时不用for
比较以下两个句子：
How long does it take you to
go to school on foot?
Ten minutes.
How far is it from your home
to school?
Ten minutes' walk.译为：10分钟的路程。
如果是骑车就用：Ten
minutes' ride.
如果是开车就用：Ten
minutes' drive，因为drive 也有名词的形式
take 有三种意思：
译为:带走，乘坐，花费
take sb. to +地点带某人到某地
take sb. to do sth带某人去做某事
11.比较以下花费
a. take 主语是it 后跟to do ，一般指花费时间
句型结构是：It takes sb.+时间+to do sth.
b. spend 主语是人后跟doing，既可以花费时间，也可以花费金钱
句型结构是：Sb.+spend+时间或者金钱+（in）doing sth.
Sb.+spend+时间或者金钱+on sth.
c. pay 主语是人，与介词for连用，一般指花费金钱
句型结构是：
Sb.+pay+钱+for+sth.
d. cost主语是物，也可以是物，一般指花费金钱
句型结构是：
It 或者sth cost sb.+钱
例如:
It takes me half an hour to
watch TV every evening.
=I spend half an hour (in)
watching TV.
以上句型不能换为pay和
cost
I paid(这里用pay过去式)
100 dollars for the book.
pay还有名词报酬，工资的意思
=The book cost me 100
dollars.
at all costs不惜任何代价，无论如何
12.对一段距离提问用how far 如：对以下短语提问就用
how far ，译为多远
five kilometers
five minutes' walk
ten minutes' ride
13.from····to··· 从···到···
14.exercise 名词锻炼不可数
exercise 只有做操类，练习题才可数
