2018初中英语词汇之植物英语单词 植物英语


  Projects like installing new carpet and painting walls can release chemicals that pollute indoor air.Luckily,some houseplants moonlight as efficient purifiers.For the best results,put as many plants as you can care for in the rooms you use most.One tip:Be sure not to overwater,as too much soil moisture can lead to mold growth.




  1.English Ivy(Hedera helix)—英国常春藤


  This hearty,climbing vine thrives in small spaces.It also fares well in rooms with few windows or little sunlight.




  How it Helps:Its dense foliage excels at absorbing formaldehyde—the most prevalent indoor pollutant,says Wolverton—which shows up in wood floorboard resins and synthetic carpet dyes.




  2.Peace Lily(Spathiphyllum)—和平莲


  Among the few air purifiers that flower,the peace lily adapts well to low light but requires weekly watering and is poisonous to pets.




  How it Helps:This year-round bloomer rids the air of the VOC benzene,a carcinogen found in paints,furniture wax,and polishes.It also sucks up acetone,which is emitted by electronics,adhesives,and certain cleaners.




  3.Lady Palm(Rhapis excelsa)—棕竹


  An easy-to-grow,tree-like species,the lady palm may take a while to start shooting upward.But once it does,its fan-like patterned leaves will add charm.




  How it Helps:Easy on the eyes,this plant targets ammonia,an enemy of the respiratory system and a major ingredient in cleaners,textiles,and dyes.




  4.Boston Fern(Nephrolepis exaltata)—波士顿蕨


  First popularized during the Victorian era,the Boston fern features feather-like leaves and curved fronds that are well suited to indoor hanging baskets.It\\\'s considered one of the most efficient air purifiers,but it can prove a bit difficult to maintain because of its need for constant moisture and humidity.




  How it Helps:This fern works especially well in removing formaldehyde,which is found in some glues,as well as pressed wood products,including cabinetry,plywood paneling,and furniture.(Some studies also show it can remove toxic metals,such as mercury and arsenic,from soil.)




  5.Snake Plant(Sansevieria trifasciata)—虎尾兰


  This sharp-leafed plant thrives in low light.At night it absorbs carbon dioxide and releases oxygen(a reversal of the process most plants undergo).




  How it Helps:In addition to helping lower carbon dioxide,the snake plant rids air of formaldehyde and benzene.




  6.Golden Pothos(Epipremnum aureum)—黄金葛


  This fast-growing vine has a reputation for flexibility.You can pot it with something to support it,plant it in a hanging basket,or train it to climb a trellis.Dark green leaves with golden streaks and marbling make it an eye-catching addition to a home or office.




  How it Helps:Like many other vines,it tackles formaldehyde,but golden pothos also targets carbon monoxide and benzene.Consider placing one in your mudroom or entryway,where car exhaust fumes heavy in formaldehyde are most likely to sneak indoors from the garage.




  7.Wax Begonia(Begonia semperflorens)—四季海棠


  Place in an area with abundant sunlight and this semiwoody succulent will produce pretty clusters of flat white,pink,or red flowers during the summer.




  How it Helps:The wax plant is a heavy hitter in filtering out benzene and chemicals produced by toluene,a liquid found in some waxes and adhesives,according to a University of Georgia study conducted last year.




  8.Spider Plant(Chlorophytum comosum)—吊兰


  A good option for beginning gardeners,the spider plant reproduces quickly,growing long,grassy leaves as well as hanging stems.




  How it Helps:Put a spider plant on a pedestal or in a hanging basket close to a sunlit window and you\\\'ll benefit from fewer airborne formaldehyde and benzene molecules.
