Checking for understanding/ Clarifying one's point or idea

Being an ESL teacher is about making a difference in people's lives. By helping students learn English, we are opening them up to varied international opportunities. English is the main worldwide language of diplomacy and international relations. By teaching students English, they learn a language with which they will be able to express themselves on an international platform. English is also the world's most widely used language in publishing, so by teaching students English, we help open them up to a wealth of information resources. By being ESL teachers we also get to fulfill our calling.
