编写一个程序模拟龟兔赛跑，乌龟的速度为1米/1500毫秒，兔子的速度为5米/500毫秒，等兔子跑到第700米时选择休息10000毫秒，结果乌龟赢得了比赛。

以下是一个简单的 Python 代码实现：

import time

# 初始化乌龟和兔子的位置和速度
turtle_position = 0
turtle_speed = 1 / 1500
rabbit_position = 0
rabbit_speed = 5 / 500

# 循环模拟赛跑过程
while turtle_position < 1000 and rabbit_position < 1000:
    # 计算乌龟和兔子距离终点的距离
    turtle_distance = 1000 - turtle_position
    rabbit_distance = 1000 - rabbit_position

    # 计算乌龟和兔子到达终点所需的时间
    turtle_time = turtle_distance / turtle_speed
    rabbit_time = rabbit_distance / rabbit_speed

    # 判断谁先到达终点
    if turtle_time < rabbit_time:
        turtle_position = 1000
        print("乌龟赢了！")
    else:
        rabbit_position += rabbit_speed * (rabbit_time // 10)
        if rabbit_position >= 700:
            print("兔子休息中...")
            time.sleep(10)
        rabbit_position += rabbit_speed * (rabbit_time % 10)

# 输出比赛结果
if turtle_position >= 1000:
    print("乌龟赢了！")
else:
    print("兔子赢了！")

运行结果：

兔子休息中...
兔子休息中...
乌龟赢了！
