One possible version:

     In the picture, a man is doing high jump, but the crossbar is fixed too high for him and he is trying to

get over it by jumping from a stool. What a ridiculous scene!

     The picture wants to remind us of setting a goal based on one' s ability, but not to cheat for an

unreasonable one. The bar is too high for the man, so he tries to get over it by jumping from a stool.

Obviously, what he does is nothing but cheating. In fact, if he sets the bar at a proper height, he is sure

to make it without the stool. So it is with our life. Some people set a goal beyond their ability and then

try to achieve it in a dishonest way, which should be strongly criticized. So we should set an attainable

goal and achieve it honestly. That' s true success.
