语法--⼀般将来时
⼀般将来时表⽰将来某⼀时刻发⽣的动作或状态，或将来某⼀段时间内经常进⾏的动作或状态。
⼀般将来时由助动词 shall / will+动词原形，或be going to + 动词原形构成
基本句型：
肯定句：I/We shall/will go. You/He/She/They Will go.
否定句 :I/We shall/will not go. You/He/She/They Will not go.
疑问句：Shall I/we go? Will you/he/she/they go?
特殊疑问句：⼀般将来时的特殊疑问句是将疑问词放在句⾸，后接⼀般疑问句
----why will you be here on Sunday?周⽇你为什么将要在这⼉？
----I will have a meeting on Sunday我将要在周⽇举⾏⼀个聚会
⼀般疑问句be或will提到句⾸some改any,and改or⼀⼆⼈称互换

----Are you going to go on an outing this weekend?
被动句：will/shall+be+v.ed（及物动词过去分词）
The letter will be sent tomorrow 这封信明天将寄出去
We shall be punished if we break the rule
⽤will或shall表⽰
“助动词will或shall+动词原形”这⼀形式，表⽰将来发⽣的事情，⽤于征求对⽅的意见或表⽰客⽓的邀请。
1. Tomorrow will be Sunday. 明天就是星期天。

2. I argued with my best friend.
argue with sb.意为“与……争吵，争论”.

（2）call sb up .打电话给某⼈。如：
I called up Zhang Hong at eight o'clock.
原句中him为代词，所以放在call和up之间，不能说成call up him.如：

注意：在动副结构的短语中，代词⼀定放在动副之间。
5. I don't want to surprise him.
“surprise sb.”，表⽰“使……惊讶”
The news surprises us greatly.
6. No, he doesn't have any money, either.
either的⽤法：⽤在否定句或否定词组后加强语⽓，表⽰“也”,“⽽且”，常⽤逗号隔开。
如：He doesn't like singing, and he doesn't like dancing, either.
either⽤作代词时，常表⽰“两者之中任何⼀个”.如：

7. I need to get some money to pay for summer camp.
（1）need是个情态动词，也可以是⾏为动词。
当它是情态动词时，后边直接加⾏为动词，表⽰“需要”，但need作情态动词时⼀般不⽤于肯定句。它⼀般⽤于否定句和疑问句中，例如：
①You need not meet him.

①He paid 10 yuan for the book yesterday.
②He spent 10 yuan on the book yesterday.
