Katie Burchfield, the high school’s English Language Learners coordinator, is testing the brothers on “sight words.” Burchfield presents a flash card with a basic English word such as “red” or “room” or “see” and the brother who can verbalize it first wins. Hilario, who was only 5 when the family moved to New Hope from central Mexico, speaks English fluently. Lucio was already a teenager when he arrived in the U.S., and though he understands English very well, his verbalization isn’t quite as fast as his younger brother’s.
