    Trees don't look at the calendar to see when spring arrives,but they seem to know when spring ishere better than we do.Recently a research takes a look at why trees in cities are turning green earlier thanexpected.The annual shift from winter to spring is a breathtaking event to watch as leaves become greenand a lush(苍翠的)environment reveals itself.While it may be winter,trees in cities are turning green earlier than expected and one of the reasonsis artificial light.City lights brightening the night skies,billboard signs lit up on roadways,and carheadlights all contribute to shifting the regular day to night cycle that plants and trees rely on.In order to stay alive during cruel winters,trees hit the pause button on their growth.Sincetemperatures can vary dramatically throughout the winter the length of daylight is the signal trees look forto safely start growing again and turn green.On average cities are typically 1.8 to 5.4F warmer than rural areas.This is known as the urbanheat island effect.The changes in city environments may affect seasonal changes even more than climatewarming and can affect the allergy (and mosquito season,water cycles,and also affect pollinators(授粉媒介).Scientists use satellite imagery to see when plants turn green.By comparing spring green-ups in the85 largest US cities scientists found that on average trees start to turn green nine days earlier in cities dueto the combined effect of urban heat effect and artificial lights.Despite the worries and concern,it isn't all bad news."With a longer growing season,trees would be able to absorb more carbon dioxide,"A researchersaid."Hopefully they'd have a longer period to do the cooling effect that can help mitigate the urbanheating effect in cities."28.Which might be a factor causing trees to turn green earlier according to the text?A.Timely rain.B.Devoted care.C.Street lamps.D.Noise pollution29.What can we say about the research findings?A.Cities are generally 5.4F colder than rural areas.B.The length of daylight influences when trees start growing.C.Changeable water cycles may cause urban heat island effectD.Urban heat causes trees to green up 9 days earlier on average.30.What does the underlined word"mitigate"in the last paragraph mean?A.Relieve.B.Enhance.C.Establish.D.Release.31.In which section of a website can the text be found?A.Business.B.Education.C.Life kit.D.Environment.高三英语第5页(共10页)扫描全能王创建
