三年级下语法
一般将来时
一、 一般将来时的定义：
一般将来时表示在将来时间将要发生的动作或存在的状态，与表示将来的时间连用。tomorrow, next day(week, month, year…),soon, the day after tomorrow（后天）等。
如：She will visit Shanghai tomorrow.

二、 一般将来时的构成
1．主语+shall/will+do
2. 主语+ be going to + do 在表示“打算到某地去时”由于谓语动词go与going重复，一般可以只说be going to a place。

三、 一般将来时的用法
1．主语+shall/will+do (will可用于所有人称，shall只用于第一人称I和we) 这种结构不是表示自己的打算、意图或计划，而是表示未来的事实或对将来的预测等如：
No one will do heavy work.
Roberts will do everything for us.
2.主语+ be going to + do这种结构常用来表达自己打算做某事、计划做某事或者有意做某事。注意：be 动词要与主语的人称和数一致，如：
I am going to do some reading tomorrow.
He is going to have a piano lesson next week.
We are going to have a party this Friday.

四、 通常情况下will 和 be going to能互换，但是be going to 与will 用法的也是有点区别的
1. 只用will不用be going to的情况:
①表示对未来时间与年龄的推测时，如:
Tomorrow will be Monday.
She will be thirteen next year.
②表示必然发生时,如：
Fish will die without water.
People will die if all green plants die.
2.只用be going to而不用will的情况：
如果表示已有迹象表明在不久的将来要发生的事情时，如：Look at those black clouds, It’s going to rain.
五、一般将来时的句式变换
肯定句：主语+shall/will+do
主语+ be going to + do
否定句：主语+shall/will+not+do（will not 可缩写成won’t）
主语+ be+ not+ going to +do
一般疑问句：shall/will+主语+ do
be+主语+going to+do
特殊疑问句：疑问词+ shall/will+主语+do
疑问词+be+主语+going to+do

Was，were的一般过去时
一、be动词包括“am”, “is”, “are”三种形式。
1. 第一人称单数(I)配合am来用。句型解析析：I am+…
2. 第二人称(You)配合are使用。句型解析：You are+…
3. 第三人称单数(He or She or It)配合is使用。句型解析：She(He, It) is +…
4. 人称复数 (we /you/they)配合are使用。句型解析：We (You, They) are +…

be动词前面的人称，是不可随意替换的。
例如I am, You are, She is，并不会出现I is, You am, She are 这样的情形。

二、Be动词在一般过去时中的变化：
1． am 和is在一般过去时中变为was。（was not = wasn’t）
2． are在一般过去时中变为were。（were not = weren’t）
3． 带有was或were的句子，其否定、疑问的变化和am, is, are一样，即否定句在was或were后加not，一般疑问句把was或were调到句首
