9、h”If we know when a building is going to collapse，we can repair it in advance or get out of it before it falls.Now，scientists at the University of Illinois have developed a material that turns red before it breaks.The invention could be used in things like climbing ropes or bridge supports.The resea
10、rch was led by Nancy Sottos，a professor at the universitys Beckman Institute，and Douglas Davis，a graduate research assistant.The secret behind the colorchanging material is a type of molecule (分子)A molecule is a group of atoms held together by chemical bonds.Imagine you and your friends standing in
11、a circle，holding hands.Each person stands for one atom，your hands represent the bonds，and the entire circle represents a molecule.If one person lets go of his or her hands，the molecule changes color.The research team put the molecule into a soft material.When the researchers stretched the material，i
12、t turned bright red for a few seconds before it broke into two pieces.When they repeatedly stretched and relaxed the material，without breaking it，it only turned a little red.The major problem is that light can get rid of the red color.When the team shone bright light on the molecule，the broken bond
