There is no present without the past although we (live) in the twentieth century, many people (be interested) in things that (happen) in the sixteenth century or (happen) in the twenty-first century. a lot of films, books and plays (be) about historical subjects or science fiction.* one day you (watch) a film about henry viii, and the next day (read) a book about men on mars. we must remember though that the present (come) from the past, and the future (come) from what (happen) now. it (be) difficult to imagine man in different ages. what (feel) it like to live in the thirteenth century? what (eat) we in the year 2000? of course, we (know) a lot about what (happen) in the past. there (be) books that (describe) the past, letters and things from the past centuries. but what it (be) like in the twenty-second century? historians (look) at our clothes and (laugh)? they (be surprised) that our transport (be) slow, and our life busy? they (think) that our food (be) strange? perhaps they (think) we (be) lucky to live in a world which still (have) some room and where people (be) happy. or perhaps they (be) happy living on the moon or even mars and (stay there and not wonder) about what (happen) on earth.
