In Africa, when the antelope wakes up every morning, the first thing         31.           comes into his mind is, “I must be able to run   32.       (fast) than the fastest lion,  33.            I will be killed by a lion.” And at just the same time, the lion   34.         (wake) out of his dream, and the first thing          35.             (flash) into his mind is: “I must be able to catch up with the slowest antelope, otherwise I will starve to   36.             (dead).” So almost at the same moment   37.         the antelope and the lion jump to their feet, and start  38.              (run) toward the rising sun.
Such is life —   39.         you are an antelope or a lion, you ought to dash forward without   40.         (hesitate) when the sun rises.
