14、uting oceans，killing wildlife and getting dumped in landfills where they take up to 1000 years to decompose. Researchers have been unsuccessfully looking for a solution.The 16yearold Canadian high school student，Daniel Burd, from Waterloo Collegiate Institute, has discovered a way to make plastic ba

15、gs degrade（分解） in as few as 3 months，a finding that won him first prize at the CanadaWide Science Fair，a $10 000 prize，a $20 000 scholarship, and a chance to revolutionize a major environmental issue.Burds strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms

16、 （微生物）. If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.With this goal in mind, he ground plastic bags into a powder and concocted（调制） a solution of household chemicals, yeast（酵母） and tap water to encourage microbes g

17、rowth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally，he tested the resulting bacterial culture on plastic bags，exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed （暴露） to the live bacteria was 17% lighter than the

18、 control after six weeks.The inputs are cheap：maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide. “Almost every week I have to do chores and when I open the closet door, I have piles of

19、 plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer：not much.

A. plastics can get hot easily B. microbes can produce heat themselves C. much carbon dioxide is produced D. the temperature can

22、 be controlled4. Daniel Burd got his idea from _. A. his school textbook B. the failure of researchers C. his everyday work D. the practice of other people（四）（2010山东烟台检测）There has been a dramatic increase in the number of natural disasters over the past few years，and it is assumed that global warmin

23、g and climate change could cause even more disasters in the future. Some of the worlds leading cities are facing disasters like floods and heat waves.LondonLondons flood defences are getting older. Since 1982, the Thames Barrier（水闸）has protected the city from the threat of flooding，but it was only d

24、esigned to last until 2030 and close once every two or three years. About 21 years later the barrier now closes five or six times a year and according to Environment Agency predictions, by 2050 the barrier will be closed on almost every tide if the problem is not addressed.There are 26 underground s

Heat waves of similar intensity（强度）are expected every seven years by 2050, so what can be done to make sure such a disaster does not happen again?One solution is to have air?conditioners installed in elderly care homes. But this is considered a short?term solution, as the increase in demand for electricity also increases carbon emissions.In Paris the local authorities are encouraging architects to design new types of building
