Here is a Cultural Literacy worksheet on assimilation, used to mean the process by which immigrants internalize and, well, assimilate, the social and cultural mores of the nation to which they have immigrated (without, one hopes, losing the social and cultural mores of the nation from which they have emigrated; for if they do, where we will get the wonderful varieties of ethnic food that have entered the American diet since my childhood?).
Anyway, this is a half-page worksheet with a reading of one compound sentence and two comprehension questions.
