　　其结构有如下几种: 1)will + 动词原形(will可以用于任何人称) 需要注意的是当主语是第一人称时will可以换成shall,特别是在以I或we作主语的问句中,一般用shall.  e.g. Shall we go to the zoo?  2)be going to +动词原形 3)现在进行时也可表示将来,前边已经讲过,这里不在重复.

　　第一种结构的句式变化是: 变否定句在will后边加not. 变一般疑问句把will提前. e.g.  She will be back in three days.  She will not be back in three days.  Will She be back in three days? 第二种结构的句式变化要在be上做文章. E.g. They are going to clean their classroom.  They are not going to clean their classroom.  Are they going to clean their classroom?
