What are some of the biggest scientific discoveries in the history of humans? How have they changed our lives? Are all the scientists born with creativity?

There was once a famous scientist who made several important discoveries. Once he was asked how he was able to be so creative. He replied that it all came from an experience he had with his mother at the age of 2. He was trying to take a bottle of milk out of the fridge. But the bottle was too slippery and he dropped it. The kitchen was covered in milk.

When his mother came into the kitchen，instead of shouting at him or punishing him，she said，"Robert，what a great and wonderful mess you have made！I have never seen such a huge puddle（水坑）of milk. Would you like to play in the milk for a few minutes before we clean it up?"

So he did. After a few minutes，they cleaned it up together. Then his mother said，"This was a failed experiment（實驗）in how to carry a big bottle of milk with two small hands. Let's go out in the backyard and fill the bottle with water and see if you can find a way to carry it without dropping it.”

The little boy learned that if he held the bottle at the top near the mouth with both hands，he could carry it without dropping it. What a wonderful lesson！

The scientist then added that it was at that moment that he knew he didn't need to be afraid to make mistakes. He learned that mistakes are just chances to learn something new which is after all, what scientific experiments are all about. Even if the experiment doesn't "work", we can still learn something valuable from it.

2.What did Robert's mother do after he made a mess?

3.From the passage, we know Robert________________.

A.started his scientific discoveries at the age of 2

B.used to like drinking milk and be very careless

C.usually treats mistakes as chances to learn something new instead of being afraid of them

4.From the last paragraph, which opinion may the writer support?

A.Mother plays the only important role in children's future life.

B.To be creative, we should keep an open mind about mistakes.

C.Scientific experiments must be valuable.

5.Which of the following words best describes Robert's mother?
