I recently heard a story about a famous research scientist who had made several very important medical breakthroughs. What set him so far apart from others?

Hethat, in his opinion, it all came from anfrom his mother that happened when he was about 2 years old. He had been trying toa bottle of milk from the refrigerator when he lost his on the slippery(光滑的) bottle and it , making its contents pouring all over the kitchen floor.

When his mother came into the kitchen, instead ofat him, giving him a lecture, or punishing him, she said: “Robert, what an(a)and wonderful mess you have made! I haveseen such a huge pool of milk. Well, the damage has already been done. Would you like todown and play in the milk for a fewbefore we clean it up?”

Indeed, he did. After a few minutes, his mother said: “You know, Robert,you make a mess like this, you have to clean it up at last and restore everything to its proper. So, how would you like to do that? We could use a sponge, a towel, or a mop. Which do you?” He chose the sponge and together theyup the milk.

His mother then said: “You know, what happened just now is aexperiment in how effectively to carry a big milk bottle with two tiny hands. Let’sout in the back yard and fill the bottle with water and see if you cana way to carry it without dropping it.” The little boythat if he held the bottle at the top near the lip with both hands, he could carry it without dropping it.

We’re raising children!

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

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.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.  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. 4. 

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

Koalas are pictured everywhere in Australia-on cleaning products, on “boxes of chocolate, on sports team shirts. Yet the animals live only in pockets along the east coast.

They once inhabited the entire coastline. The koala population dropped after farmers cut down many of the forests where koalas lived, and hunters killed the animals for their fur.

By the early 1900s, “koalas were basically shot out of south Australia,” says ecologist Bill Ellis, who studies the relationships among living things and their environments.

I recently joined Ellis and his team in a forest on St Bees Is land, 19 miles off the northeastern coast of Australia, with eight other volunteers. The island is a natural laboratory, yielding findings that may help protect koalas elsewhere on the continent.

The volunteers searched the island for koalas in the blue gum trees. When we found a koala, we gathered information about the trees in the area.

Blue gum is a species of the eucalyptus tree in which the funny leaf eaters spend most of their time. Eucalyptus trees are native to Australia, and their leaves are the main food source for koalas. Although koalas can walk on the ground, they are better suited for life in the canopy, the high cover of branches and leaves in a forest.

What has Ellis’s research told him so far? The population of St Bees seems to be healthy. Yet Ellis wonders whether the koalas might be heading for hard times. The island is overrun with wild goats, and Ellis thinks the goats are eating the small blue gum trees.

Without those trees, the koalas will run out of food in the future. Ellis hopes more research will help him understand how to protect the blue gum trees-and the koalas that depend on them. “I think that’s what everyone is trying to do-to make a difference.” Ellis says.

59. It can be inferred from the first paragraph that     .

         A. koalas’ pictures can be found everywhere in the world

         B. koalas in Australia like to eat chocolate

         C. only in the east coast of Australia can you find koalas

         D. you can buy the pictures of koalas only in the east coast of Australia

60. Which of the following is TRUE about koalas?

         A. They usually hide in a cave.          B. They feed on the leaves of blue gum trees.

         C. They prefer to walk on the ground.     D. They don’t adapt to the high cover of branches.

61. What will Ellis most probably start to do next?

         A. To keep the population of St Bees healthy.

         B. To kill all the goats on the island.

         C. To find some new foods for goats.

         D. To protect blue gum trees for koalas.

62. The purpose of writing this passage is to      .

         A. expect people to concern about the life of koalas

         B. record trip to Australia for watching koalas

         C. present some basic knowledge of koalas’ life

         D. introduce the ecosystem of wildlife in Australia
