We will watch the boat races and eat zongzi on that day. 二、there be句型的一般将来时结构 1. there be句型的一般将来时结构： there will be; 其否定形式是在will后直接加 not; 其一般疑问句形式是直接把will提到句首； 肯定回答为“ Yes, there will.”；否定回答为:“No, there won’t.”。 2. there be句型的一般将来时结构： there is/are going to be; 其否定形式是在is/are后直接加 not; 其一般疑问句形式是直接把is/are提到句首； 肯定回答为“ Yes, there is/are.”； 否定回答为:“No, there isn’t/aren’t”。 三、will和be going to的区别 be going to往往表示将要发生的动作或安排，特别是打算、计划、决定要做的事。 一般将来时（will）常用来客观陈述将来某个时间要发生的动作或存在的状态（will作为情态动词常表意愿）。 She is going to lend us her book. 她打算把书借给我们。 She will lend us her book. 她将会把书借给我们。 附语法思维导图： 1 学科网（北京）股份有限公司 $
