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（实验）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?

A.She allowed him to play in the mess.

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?

Butterflies are some of the most beautiful insects in the world. However, what interests the scientists most is not their fascinating looks, but how they sense nature. They use their senses of sight, touch, hearing, smell and taste to find food, lay eggs in good places and avoid hungry enemies.

Butterflies have large compound(复合的) eyes. No matter where the things are, they can see them without turning their heads. 1. They are more possible to notice a sea of flowers than a single plant. Butterflies do not "see” colors. They are color blind.　 2.The light on many flowers guides butterflies to honey.　　　

How do butterflies smell? Butterflies have a very well-developed sense of smell, but it is not in their noses, since they don't have one. Sense organs (器官)are in their feet, and many other parts of the body.3.

Do butterflies use their mouths to taste the food they find? Not really. Butterflies' feet have sense organs that can taste the sugar in flower honey. They let the butterflies know if there is something delicious. 4.They feed their babies using a long tube(管道)，and they get all their food from this tube as well.　　

Butterflies don't have ears. Instead, they “hear" sounds through their wings by sensing changes in sound vibrations(震动).Butterflies' body is covered with sensory hairs. 5..For example, the hairs give butterflies information about the wind when they're flying. And where there is rain, the hairs can also tell butterflies.　

The scientists say that butterflies may have senses we don't even know about yet, because their body is very different from ours. Therefore, it is difficult to understand when we use our own human senses to study it.　　

A. Like most insects, butterflies are very nearsighted.　　

B. They can let butterflies feel the environment around.

C. So it is not difficult for butterflies to find flower honey.

D. But they can sense sunlight, which tells them the direction.

E. They can help butterflies find their favorite flower honey food.

F. Some female butterflies taste the plants carefully to find places to lay eggs.

It’s important to have some friends in your life. The following types of friends are just what you need to keep happy.

1. A Loyal Best Friend

Sometimes a loyal best friend is the only thing you need to stay calm. Everyone needs a friend who will support them at any time. He knows all of your deepest and darkest secrets, but still loves you all the same.

2. A Friend From a Different Culture

If everyone had a friend from a different culture, the world would be a much better place. Being in a cross-cultural friendship allows you to explore customs, values, and traditions outside of your own culture. Perhaps you can learn some new ways to do things.

So, don’t be afraid of someone that is from a different culture. Instead, keep your mind open, and make the effort to learn about something different while getting to know the person.

3. A Friendly Neighbor

These days, a lot of people don’t know their own neighbors. It’s a pity, because some neighbors can help you a lot sometimes. If you’re on a vacation, and you suddenly realize that you forgot to lock the door, you can call up your neighbor and ask them to lock it for you.

4. A Work Pal

What is color? Why do some of the things around us look red, some green, others blue?

Colors are really made by reflected(反射)light. We see color because most of the things reflect light. Something is red, for it reflects most of the red light. In the same way, if something is green, it reflects most of the green light. If something reflects all light, it is white. If it doesn’t reflect any light, it is black.

Some of the light is reflected and some is taken in (吸引)and turned into heat. The darker the color is, the less light is reflected, the more light is taken in. So dark-colored clothes are warmer in the sun than light-colored clothes.

根据短文内容，判断正(T)误(F)

1.When something reflects light, we can see its color.

2.Something looks white because it reflects all light.

3.The dark-colored clothes are warm because less light is taken in.

4.In summer light-colored clothes make people feel cool.

5.Color is the best title of this passage.
