 Now let's take a look at the present continuous tense. The continuous tense is used to talk about actions in progress at the time of speaking or around the time of speaking. The first thing to notice with the continuous tense is that we must use the verb plus ing form, also known as the present participle. You'll see it in any continuous tense, especially with the present continuous. We have three different forms of this tense. First we have the subject I, used with am, teaching. Then we have you, we, and they, are, teaching. Finally we've got he, she, it, is, teaching. The am, are, and is are forms of the verb to be, and here with this tense it's used as an auxiliary verb or a helping verb. In order to form negative sentences we simply add the word not between our helping verb and our main verb plus ing. To form the questions for the present continuous tense, again what we've done is inverted our helping verbs here and our subjects here, resulting in questions like am I teaching? Are you teaching and is he teaching?
