四年级下册英语素材一般将来时态be going to的用法与练习 全国通用.doc

语法知识：be going to do sthbe going to句型的两种不同用法 Im going to the school.我正要去学校。Im going to go to the school.我打算去学校。第一句是动词go的进行时表将来，(to)之后须加名词。(come, go等趋向动词的现在进行时表将来。)第二句则为be going to的一般将来时句型，to之后须加动词原形。一般将来时一、概念：表示将要发生的动作或存在的状态及打算、计划或准备做某事。句中一般有以下时间状语：tomorrow, next day(week, month, year), the day after tomorrow（后天）等。二、基本结构：be going to + do；be going to的特殊疑问句形式：构成方式：疑问词be going to的一般疑问句。一个口诀献给大家： 疑问词在句首，系动词be跟着走，主语、going紧相随，其它成分不要丢。如何把陈述句形式转换成特殊疑问句形式呢？一个方法，那就是：一定、二变、三去掉。一定：即确定划线部分的疑问词；二变：即把be going to变为一般疑问句形式；三去掉：去掉划线部分。例如：We are going to have a meeting next Monday.A：确定疑问词为when(什么时候)B：把原句改为一般疑问句are you going to have a meeting next Monday?C：去掉划线部分，即When are you going to have a meeting?你们打算什么时候开会？【注意】如果对to后面的动词短语进行提问则要用What.do.?对例句中的have a meeting进行提问应为：What are you going to do nextMonday? 下星期一你们打算做什么？【特别警示】当划线部分为主语或主语的定语时，特殊疑问句的语序为陈述句语序。Miss Li is going to teach you 三、否定句：在be动词（am, is, are, was, were）例如：Im going to have a picnic this afternoon. Im not going to have a picnic this afternoon.四、一般疑问句： be提到句首，some改为any, and改为or，第一二人称互换。例如：We are going to go on an outing this weekend. Are you going to go on an outing this weekend?五、对划线部分提问。一般情况，一般将来时的对划线部分有三种情况。1、问人。Who 例如：Im going to New York soon. Whos going to New York soon.2、问干什么。What do.例如： My father is going to watch a race with me thisafternoon. What is your father going to do with you this afternoon.3、问什么时候。When.例如：Shes going to go to bed at nine. When is she goingto bed?六、同义句：be going to = willI am going to go swimming tomorrow（明天）. = I will go swimming tomorrow. 3. be going to 含有“计划，准备”的意思，如： She is going to lend us her book. 5. be going to用法口诀： be going to跟“动原”，计划、准备或打算； 表可能，有必然，通过现象来判断。 be的形式要注意，它要随着人称变， 否定句，很简单，not加在be后边； 疑问句，需牢记，be应提到主语前。 Be going to练习I.选择适当的词填空。1.
