外研社一起小学三年级下语法总结及练习题.docx

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+do2. 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: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. 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, Its 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wont） 主语+ be+ not+ going to +do一般疑问句：shall/will+主语+ dobe+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练习题一、按要求填空1. 我打算明天和朋友去野炊。 I_ _ _ have a picnic with my friends.
