1、be going to表达的将来时态的概念，是表示说话人打算最近或将来要做的事情。强调计划和打算。结构：be going to do其中
be是助动词，do是行为动词，代表动词原形，具体用在句子中be要变为：
+ going to do
eg：I'm going to fly kites this afternoon.
We are going to play football after class.
Wei Hua is going to do some shopping tomorrow morning.
否定句：
+ not + going to do
I'm not going to meet my friends at the bus stop.
They are not going to climb the hill next Sunday.
一般疑问句：
Are you going to clean the classroom this afternoon?
Is she going to wash her hair?
特殊疑问句：
wh- +一般疑问句
What are you going to do this afternoon?
When is he going to play football?
Where are they going to fly kites?
How much meat is she going to buy?
在英语中go, come, leave等词的现在进行时可以表示将来，就不必出现be going to do的情况了。例如：
Are we going to the Great Wall tomorrow?
The train is leaving. 火车要开了。
Look! The bus is coming! 看！汽车来了！
学习一个时态，同时要学习其时间状语：
this afternoon 今天下午
this evening今天晚上
tomorrow 明天
2、Why don't you come with me? 为什么不……呢？
这个句型常用来提出建议，不需要回答。
Why don't you tell us about that? 为什么不告诉我们有关那事呢？
Why doesn't he go there by plane? 为什么他不乘飞机去呢？
这个句型还可用另一种形式表达：
Why not + 动词原形…？
Why not have some mooncakes?
Why not read English in the morning?
3、let动词，“使”、“让”的意思，它的后面可以跟不带to的不定式，记为：let sb. do sth.
eg：Let me see.
Let's go!
Let him watch TV.
Let's sing a song.
Let me have a look.
4、a few = some与可数名词连用
We're going to Da Lian for a few days. 我们要去大连几天。
I have a few friends. 我有一些朋友。
注意：few表示几乎没有，带有否定含义。
Autumn is coming. There are few flowers over there. 秋天到了，那边几乎没有花了。
Few people like to see the film. 几乎没有人爱看这部电影。
5、It's much better than having class. 摘苹果比上课好得多。
It在这句中是指picking apples, 即摘苹果。所以这句话也可以说成：
Picking apples is much better than having class.
本句中picking是动名词，picking apples是动名词短语做主语，它和后面的having达成一致。
eg：Playing football is good for your health.
本句中的much是副词，修饰比较级better，表示“比……的多”，much better是“好得多”，而very 却不能这样使用。
eg：Lin Tao is much taller than Mike. 林涛比迈克高得多。
They are working much harder this term. 他们这学期用功得多。
6、It's time for class. 该上课了。
这个句型可以演变为四种形式，请同学们注意学习。
It's time
eg：It's time to go to school. 还可以说成：liuxuepaper.com
