Question：1.What do you think of this poem？

                   2.Do you know  what time to eat the apple？

        An apple a day
        Sends the doctor away

        Apple in the morning
        Doctor's warning

        Roast apple at night
        Starves the doctor outright

        Eat an apple going to bed
        Knock the doctor on the head

        Three each day, seven days a week

        Ruddy apple, ruddy cheek

注：ruddy cheek  红润的脸颊
