When it comes to communication, speaking is not the only way to express how we feel. We always use a lot of non-verbal ways to show our 66 other than just using words. Facial expression is one of the ways to reveal how we feel. For instance, when someone is speaking to us, we may wear a smile to show that we agree to 67 he or she has to say. If we don’t understand someone we’re talking to, 68 ,we may frown or scrunch up our nose and forehead, which is a typical expression of confusion. Sometimes we even use body language to help us 69 express our emotions. When we see someone cross arms, he or she may be impatient. Or when we see someone nodding their heads or bowing while listening to a conversation, the gesture may signify their agreement with another person’s opinions. So, next time you have trouble 70 with someone in spoken languages, maybe you can try different ways to make it easier for you two to understand each other
