Grammar rules→p144 现在进行时 如果要表达现在正在做的事情该用什么句式呢？动词有没有什么变化？ 首先让我们来看几个例子： Tony is eating a delicious ice cream. Tony正在吃一个美味的冰激凌。 Daming is having lunch.大明正在吃午饭。 We are playing football.我们正在踢足球。 以上例子都用了现在进行时表示正在做的事情。可以看出，现在进行时采用be+动词-ing的形式。其中be的变化与上一单元学过的be随人称变化而变化的规律一样，动词-ing形式的变化规律如下表所示： 规则 示例 一般情况下，动词后直接加-ing working, buying, visiting, talking, saying 以字母e结尾的动词，去掉e，然后加-ing taking, having, leaving, driving, writing, making 以辅音字母+元音字母+辅音字母的重读闭音节结尾的动词，如果末尾只有一个辅音字母，双写这个辅音字母，然后加-ing stopping, shopping, sitting, getting 特殊变化 lie-lying 既然在谓语部分用了be, 结合前面的例句我们不难得出：现在进行时的肯定和否定形式构成与我们学过的be的相关句式构成是一样的，如下表所示： 肯定句 否定句 I am writing a letter. I am not writing a letter. He/She is listening to music. He/She is not (isn’t) listening to music. We are enjoying our trip. We are not (aren’t) enjoying our trip. They are talking to each other. They are not (aren’t) talking to each other. 根据现在进行时的构成特点，其一般疑问句采用如下表达方式： Is she doing her homework 她在做作业吗？ Are you listening to music 你(们)在听音乐吗 Are they learning English 他们在学习英语吗 如果要询问对方是否在做某事，或是询问对方在做什么，我们要采用现在进行时的疑问句形式。 其回答方式也与含有动词be的疑问句式的回答一样，如下表所示： 疑问句 回答 Is she cleaning the house Yes, she is. No, she isn’t. Are you getting ready for the Spring Festival Yes, I am /we are. No, I’m not /we aren’t. Are they sweeping the floor Yes, they are. No, they ... ...
