六年级上Unit6 Keep our city clean 单元语法速学
1.can 和 could 的区别与联系。
a.can的过去式是could。如:
He can drive a car.他会开车。
He could drive a car two years ago.他两年前会开车。
b.could除了可作can的过去式外，还可表示比can更委婉的语气，因此在回答由could表示请求的问句中，不能用could,但可用can。如:
Could you lend me a hand?你能帮我一下吗？ — of course I can.当然可以。
c.与感觉动词连用时，can, could可互换。如：
We could/can smell something burning in the kitchen.我们闻到厨房里有东西烧焦的味道。
make+复合宾语（名词或代词+形容词）表示“使...变得...”。
如：What makes our city dirty?
什么使我们的城市变脏了？
Rubbish makes the streets messy and dirty.
垃圾使街道变得又脏又乱。
3.can用于提出建议，意思是“可以”。如：
What can we do to keep our city clean?
我们怎样做可以保持城市洁净。
We can take the bus and the metro to school.
我们可以乘公交和地铁上学。
We can plant more trees to keep the air clean.
我们可以种更多的树，让空气保持清洁。
4.move ... away的意思是"搬走”、“移走”。如:
We can move some factories away from our city.
我们可以把一些工厂从城市搬走。
5.help keep the air clean有助于保持空气洁净
keep the air clean是动词不定式，作help的宾语，接在help后的动词不定式通常省略to,尤其在非正式用语和口语中。如：
Can you help (to) open the window? 你能帮忙打开窗子吗？
Let me help (to) sweep the floor. 让我来帮忙扫地吧。
6.pick up的用法
pick...up是个由动词加副词构成的动词短语，需要注意以下几点：

Pick up the banana skin. = Pick the banana skin up.把香蕉皮捡起来。如：
Put on the coat. = Put the coat on. 把外衣穿上。
(2)如果宾语是代词，代词一定放在中间，如：
Pick it up.把它捡起来。Put it on.穿上它。

Li Lei's book = book of Li Lei 李雷的书
(2)无生命的物体的名词所有格一般用of短语的形式，如：
