In the beginning of the episode, Teacher Mina expresses that she's a scaredy cat and Teacher Marilou tells us that she's a cry baby. They then go on to discuss Teacher Mina's reactions to certain situations. For today's grammar point, Teacher Marilou teaches you that for "Zero Conditional" you use the present tense of the verb in both the 'if-clause' and the 'main clause.' For example:  (1) I get dizzy if I ride a car. ; (2) If I don't exercise for a long time, I get tired easily. Teacher Marilou also highlights that swapping the if-clause and the main clause doesn't change the meaning of your sentence. Learn more about us through exl-english.com.
