12、 are still art projects to finish.Schergen leaves behind a richlegacyat this school.Hes won grants(拨款)for art projects.He turned an empty classroom into a museum.Hes pushed his students to make art about their lives.And he was awarded a Golden Apple the most honorable teaching award in Chicago.But i

13、t wasnt always easy.For years,Schergen taught in one of the citys toughest neighborhoods.“When I first got my room,I noticed there were bullet holes in the window.That made me nervous,”he says.So he stuffed Beanie Babies in the holes to make it“look kind of funny”.“I didnt even tell my wife for a wh

15、signaling him over.He bends down for a hug.“Thank you for making these last days special and being a help to me.”When Deontae leaves,a reporter asks Schergen:When your kids ask why youre retiring,what do you tell them?“I just tell them that grown people have dreams too,”he says.“I have other things

19、f eastern Australia are home to a stinging tree known as Dendrocnide.Many people callit the gympie-gympie treea name given to the tree by native Australians.Its covered with sharp,needle-like hairs that carry poison.If you touch a gympie-gympie tree,you wont forget it anytime soon.The pain can stay

20、with you for hours,days or weeks.In some cases,its been reported to stay for months.Scientists have long looked for the source of this powerful sting.Now researchers at the University of Queensland have discovered what makes this stinging plant so painful.After carefully studying different kinds of

21、gympie-gympie trees,the scientists were able to separate out different chemicals that the trees produce.This allowed them to identify a group of chemicals that they believed was responsible for the pain.The researchers created artificial versions of these chemicals,which they call“gympietides”.Sure

22、enough,when the scientists injected mice with gympietides,the mice licked(舔)at the places where theyd been injected,indicating that they hurt in those places.When the scientists studied the way gympietides were built,they found that they formed a knot-like shape.The shape makes the chemicals very st

23、able,which helps explain why the pain stays so long.The knot-like shape of the gympietides was similar to the shape of poisons produced by poisonous spiders and cone snails.The scientists were surprised to see three very different kinds of life all using similar poisons.Spiders and cone snails carry

24、 poisons because they catch food by stinging other creatures.Its not clear how stinging helps the gympie-gympie tree.Though the trees sting may stop some animals from eating it,it doesnt stop all animals.Beetles and pademelons(small s of the kangaroo)are able to eat the plant without trouble.8.Why i

29、ive when their workplaces were decorated with houseplants.The engineers at the Massachusetts Instituteof Technology(MIT)have taken it a step further changing the actual composition of plants in order to get them to perform diverse，even unusual functions.These include plants that have sensors printed

30、 onto their leaves to show when theyre short of water and a plant that can detect harmful chemicals in groundwater.Were thinking about how we can engineer plants to replace functions of the things that we use every day,explained Michael Strano,a professor of chemical engineering at MIT.One of his la

31、test projects has been to make plants glow(发光)in experiments using some common vegetables.Stranos team found that they could create a faint light for three-and-a-half hours.The light，about one-thousandth of the amount needed to read by，is just a start.The technology,Strano said,could one day be used

32、 to light the rooms or even to turn trees into self-powered street lamps.In the future，the team hopes to develop a version of the technology that can be sprayed onto plant leaves in a one-off treatment that would last the plants lifetime.The engineers are also trying to develop an on and offswitchwh

33、ere the glow would fade when exposed to daylight.Lighting accounts for about 7%of the total electricity consumed in the US.Since lighting is often far removed from the power source(电源)-such as the distance from a power plant to street lamps on a remote highway-a lot of energy is lost during transmis
