C

I was riding along the road when I heard someone shouting behind me. It was a young shepherd (牧羊人). He was running across a field, and pointing at something.

I looked and saw two wolves running across the field. One was fully grown, the other was a cub. The cub had on his back a lamb (羔羊) which had just been killed, and he had the leg in his mouth. The old wolf was running behind.

As soon as I saw the wolves, I joined the shepherd and started in pursuit (追击), setting up a shout.

When they heard, some peasants started out also in pursuit, with their dogs.

As soon as the old wolf caught sight of the dogs and the men, he ran to the young one, snatched (攫取) the lamb from him, threw it over his back, and both wolves increased their pace and were soon lost from view.

Then the shepherd began to tell me how it happened. The big wolf has sprung (跳跃) out from the valley, seized the lamb, killed it and carried it off. The old wolf allowed the young wolf to carry the lamb, but kept running a short distance behind.

But as soon as there was danger, the old wolf stopped giving the lesson, and seized the lamb himself.
