The Present Continuous

用于描述正在发生的事情，比如穿的什么，在做什么之类的

一般形式

She is wearing a red dress.
形式为：subject + "to be" + verb-ing + the rest of sentence
注意：

1. 动词（verb）结尾为“e”的话，去掉“e”再加ing，比如use -> using, dance -> dancing
2. 最后三个字母是consonant + vowel(a, e, i, o, u) + consonant，并且句中该元音字母重读，双写加ing，比如cut -> cutting

Negtive

He is not wearing a hat.
subject + "to be" + not + verb-ing + the rest of sentence.

Present Continuous Question

What is he doing?
What is she wearing?
What are you using?
What are they eating?
形式为：question word + "to be" + subject + verb-ing
