参考答案：

As is depicted in the first picture, a farmer was working in the fields. All of a sudden he saw a hare running in the distance, only to dash itself against a big stump. The hare was seriously injured and could not move any more. The man came over and, to his delight, picked it up and went home happily. The second picture shows that the farmer was sitting near the stump, waiting for another hare to appear. But nothing similar happened at all.

The set of pictures tells us that those who dream of reaping without sowing will achieve nothing. Ironically, there are a lot of people in our life who are unwilling to make painstaking efforts but greedy for success. They tend to trust to chance and luck. My previous experiences in study and work have proven that in order to succeed, first and foremost, one should be both hardworking and persevering. We should strive for possible success. There is no reason for us to look to any accidental gain.

In my opinion, at no time and on no account should we trust to chance or luck. So my conclusion is that success results from hard work.
