American scientists have developed the first material that repairs itself. The material is a form of plastic that has been engineered to fill breaks in its surface.

Plastics are used today in everything. Scientists wanted to find a way to make objects made of plastic last longer. The researchers hope their new discovery can be used to make objects that are difficult or impossible to replace.

The surface of plastic objects breaks over time. Very small breaks develop every time a plastic object is used. The researchers wanted to find out how to stop plastic from developing small breaks that weaken and destroy it. They found the answer in the chemical structure of plastic itself. The research team found a way to make plastic that contains very small balloons filled with monomer(单体) liquid.　 When the new plastic cracks, the monomer liquid is let out and flows into the crack. Thus the break is repaired. The repaired plastic has seventy-five percent of the strength of undamaged plastic.

The new self-repairing plastic is not yet ready for production. But it has several possible uses. One could be in space vehicles where parts cannot be repaired or replaced. Another possible use might be in bridges. And it could be used in people, to replace bone joints that have become broken or damaged.

1.The passage mainly talks about_______ .

A. plastic that repairs itself

B. the chemical structure of plastic

C. permanent material invented

D. small balloons that makes plastic stronger

2.We know from the passage that the repair is done as_______.

A. the cracked plastic parts are changed

B. the plastic cracks

C. the liquid is put into the plastic cracks

D. the plastic is made

3.The scientist are planning to use the new material in space vehicles, bridges and people because________.

A. the plastic parts in them are required to last longer

B. they want to experiment in these places first

C. the new material cannot be used elsewhere

D. the plastic parts in them are easily broken or damaged
