【正确答案】　　One day Wang An passed under a big tree when a little sparrow fell down, so he decided to take it back home for care. At the doorstep, considering the fact that his mother would not allow keeping pets, he hid the sparrow behind the door secretly and walked in hastily. Unexpectedly, his mother yielded to his imploration. 　　Wang An rushed back in rapture, only to find the sparrow gone and a black cat rubbing its mouth. This incident clouded him for a long time, from which he drew a lesson that there’s no room for hesitation when it comes to a determined plan. Indecision may keep you away from some mistakes, but more likely from the chances of success.
