Thật vậy, với đặc tính sinh vật của mình, cây đa đã gắn bó sâu sắc với làng . Đa rất dễ trồng và sống lâu tới ngàn tuổi. trong bão táp phong ba, trải qua bao thế hệ cây đa vẫn sừng sững tỏa bóng mát giữa trời, ôm cả một góc quê hương. Cành đa vươn đến đâu buông rễ chùm, rễ nổi đến đó. Từ rễ hóa thành thân, để cây đa có thêm nhiều cội. Có cây có tới chín cội lừng lững uy nghiêm cả một góc làng. Những cội đa đó như những cánh tay khổng lồ, cơ bắp cuồn cuộn nâng cả tán cây lên giữa trời xanh. Ngoài những cội chính ra đó, đa còn có nhiều lá rễ chùm rễ phụ buông lơ lửng lưng trời như tóc ai đang xòa bay trong gió. Trẻ chăn trâu tha hồ ẩn náu trong từng cội đó chơi trò đuổi bắt . Lá đa xanh ngắt bốn mùa chim gọi về làm tổ. Trong vòm lá, chim ríu rít gọi bầy. Dưới gốc đa trẻ nô đùa hò hét. Và kia, con trâu nhà ai đang mơ màng lim dim nằm nhai cỏ để cho lũ chim sáo nhảy nhót cả lên đầu.
Chúc bạn học tốt!
