Welcome back to another lesson on TENSEs! In this lesson we are introducing how to make sentences in the present progressive form, such as "I'm eating." "I'm studying." and "I'm driving." The basic construction in the present tense is VERB STEM + -고 있어요 [-go i-sseo-yo], and you can find out how to say this in the past tense and the future tense as well by listening to the lesson. Be sure to answer the quiz at the end of the lesson as well!
