根据短文内容,从从短文后的选项中选出能填入空白处的最佳选项。选项中有两项是多余选项。(共5小题,每小题2分,满分10分)

We’re raising children!

A famous research scientist was being interviewed why he was so much more creative.

小题1: He had been trying to remove a bottle of milk from the refrigerator when he lost his balance and it fell, spilling its contents all the kitchen floor—a veritable sea of milk!

When his mother came into the kitchen, instead of yelling at him, she said , “Robert, what a great and wonderful mess you have made! I have rarely seen such a huge puddle of milk.小题2:Would you like to get down and play in the milk for a few minutes before we clean it up?”

Indeed, he did. After several minutes, his mother said,“You know, Robert, whenever you make a mess, eventually you have to clean it up and restore everything to its proper order.  小题3: We could use a sponge, a towel or a mop. Which do you prefer?” He chose the sponge and they cleaned up the spilled milk.

His mother then said, “You know, what we have here is a failed experiment in how to effectively carry a big milk bottle. Let’s fill the bottle with water and see if you can discover a way to carry it without dropping it.” The boy learned that if he grasped the bottle at the top near the lip with both hands, he could carry it without dropping it. 小题4: 

This scientist remarked that it was at that moment that he knew he didn’t need to be afraid to make mistakes. 小题5:  

Wouldn’t it be great if all parents would respond the way Robert’s mother responded to him?

A.Instead, he learned that mistakes were just opportunities for learning something new.

B.Well, the damage has already been done.

C.What set him so far apart from others?

D.What a wonderful lesson!E.    So, how would you like to do that?

F.    Such an opportunity of experiencing was delightful to him.

G.   He responded that it all came from an experience when he was about two years old.
