Broken rubber bands and flat tires requiring replacement could soon be a thing of the past.

学科网(www.zxxk.com)--教育资源门户,提供试卷、教案、课件、论文、素材及各类教学资源下载,还有大量而丰富的教学相关资讯!French researchers have developed a new kind of rubber that can repair itself when broken.The new rubber is made from widely available materials including vegetable oil and a common industrial chemical.All the materials are considered safe to the environment and can be easily reused.

The best part is that the new rubber can be repaired and used again and again without losing its strength or ability or stretch.When cut, the rubber can be made new again, simply by pressing the two broken ends back together.

学科网(www.zxxk.com)--教育资源门户,提供试卷、教案、课件、论文、素材及各类教学资源下载,还有大量而丰富的教学相关资讯!The product can be repaired at room temperature, around twenty degrees Centigrade;other self-healing materials require higher temperatures for repair.

Traditionally, rubber substances are made from huge molecules(分子)connected by strong chemical links, or bonds.The new rubber is made of smaller molecules.The molecules are linked together using hydrogen bonds.When connected in this way, the molecules act like one long molecule, forming what is called supramolecular networks(超分子网).When the rubber is cut, the molecules attempt to connect with whatever molecule is near them.When pressed together, the molecules are able to repair themselves at the molecular level, making the repaired rubber like new.

The rubber is the creation of scientists at the Industrial Physics and Chemistry Higher Education Institution in Paris.The organization is part of France's National Center for Scientific Research.The new material is described in greater detail in the research publication Nature.

1.According to the introduction, which of the following is NOT the advantage of the new rubber?

A.It can be made as easily as common rubber.

B.It is environmentally-friendly.

C.It can repair itself at room temperature.

D.It is made of smaller molecules.

2.What does the 5th paragraph mainly tell us?

A.Why the new rubber is unique.

B.Why the new rubber can repair itself.

C.The new rubber is made from huge molecules.

D.The new rubber is different from the common rubber.

3.If we want to know more about the technology of this kind of new rubber, where can we get the information?

A.In the researchers' diary.      B.In a guide book.

C.In a research magazine.       D.In a newspaper.

 A very little boy was spending his Saturday morning playing in his sandbox. He had with him a plastic pail (桶) and a shiny, red plastic shovel (铲). In the   36   of creating roads and tunnels in the sand, he   37   a large rock in the middle of the sandbox.

The boy dug around the rock,   38   to move it off the dirt. At first, he wanted to carry it out of the sandbox with his hands; however, it was too heavy.
