similar last year in the Sichuan earthquake.Thousands of people were buried in the ruins and lost their lives.What if we could have warned them?‎ People are always racking_their_brains to find a way of preventing buildings’ collapse.Better materials and technology help，but they are not a solution.‎ Just like humans，a building has its own life cycle from “birth” to “death”．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 research was led by Nancy Sottos，a professor at the university’s 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 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，it 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 was fixed，and the color disappeared.‎ If the bright light keeps the red color from appearing，the material’s warning system will be useless.Scientists still have a lot of work to do before the colorchanging molecules can be used outside the lab.‎ ‎16．What does the passage mainly introduce?‎ A．The collapse of an overpass in Zhuzhou，Hunan Province.‎ B．The Sichuan earthquake last year.‎ C．A material that turns red before it breaks.‎ D．A way of preventing building from collapsing.‎ ‎17．The underlined words “racking their brains” in the third paragraph mean ________.‎ A．suffering a lot B．collecting beyond imagination C．losing a lot D．thinking very hard ‎18．Which of the following is a WRONG statement?‎ A．Thousands of people died from the collapse of buildings in the Sichuan earthquake because they hadn’t been warned.‎ B．There is no building that will never collapse.‎ C．A new material has been applied to buildings to warn people of collapse.‎ D．A colorchanging material can turn red before it breaks.‎ ‎19．What is the major problem in the research of the colorchanging material?‎ A．Bright light can get rid of the red color.‎ B．When the material is relaxed，the color disappears.‎ C．The material’s warning system is useless.‎ D．The molecules only change color in the lab.‎ ‎20．What can we infer from the passage?‎ A．The colorchanging molecules are certain to be used outside the lab.‎ B．There will be no collapse with the help of the colorchanging material.‎ C．There is a long way to go before the material can be applied.‎ D．The problem caused by bright light will be solved by scientists.‎ Ⅲ. 任务型读写 Attention deficit (不足) hyperactivity (活动过度) disorder is known by the letters A．D.H.D.Children with A．D.H.D.might have trouble paying attention.They might not seem to listen and might forget things.They might not be able to stay seated or play quietly.They might talk too much，act and speak without thinking about the results of their behavior.These are among the signs named on the website of America’s Centers for Disease Control and Prevention.‎ Doctors usually identify the disorder in children.But experts say the behaviors often last into adulthood.Researchers have been looking for the cause or causes of attention deficit hyperactivity disorder.Now, a brainimaging study offers more evidence that could lead to new ways to treat it.Researchers say they observed shortages in the brain’s reward system in patients with A．D.H.D..The study found that levels of some proteins were lower than normal.Nora Volkow, director of the National Institute on Drug Abuse, says the lack of attention and selfcontrol that mark A．D.H.D. could be caused by problem in the flow of dopamine(多巴胺). She says people might have difficulty completing an activity if they cannot expect some kind of reward in return. Researchers studied the pathways on which dopamine travels and A．D.H.D. Doctor Volkow says the researchers then compared the pathways to those of 44 adults without the disorder. “There is a lower concentration of dopamine markers in the brain of individuals with A．D.H.D., specifically in the areas of the brain that are involved with reward and motivation. And the dopamine levels are directly linked to the severity of the patient’s inattention，”she says.‎ The study used brain images taken at Brookhaven National Laboratory in New York‎ ‎State. Jack Wang is chairman of the Brookhaven medical department. He says the finding might also help explain why people with A．D.H.D.are more likely to abuse drugs or overeat. He says they might be attempting to increase their dopamine levels to make up for the deficits in their reward ‎ system.(2011·合肥模拟)‎ Title ‎•The Finding of 21.________‎ The 22.______ of children with A． D.H.D.‎ ‎•Perhaps they don’t seem to listen.‎ ‎•Perhaps they are 24.________.‎ ‎•Perhaps they can’t sit for ‎25.________ or play quietly.‎ ‎•They might talk too much，act and speak without 26.__________ the results of their behavior.‎ The 27.______ of A．D.H.D.‎ ‎28.________ of brain’s reward. ‎ ‎•Levels of some proteins are lower than normal.‎ ‎•Levels of dopamine are 29.________ as well.‎ Reasons of abusing drugs ‎•They are trying to 30.________ their dopamine.‎ ‎1.B 2.C 3.D 4.A 5.B 6.D 7.D 8.C 9.D 10.A 11.D 12.B 13.A 14.D ‎ ‎15.D 16.C 17.D 18.C 19.A 20.C ‎21.A.D.H.D. 22.signs/symptoms 23.attention 24.forgetful 25.long 26.considering ‎27.causes 28.short 29.low 30.increase/raise
