Your furniture, the materials in your walls and your carpet can hold poisons. Before buying an expensive air cleaner, you􀆳d better try out a few houseplants first—they􀆳re much cheaper and look a lot nicer. Snake Plant Perfect for your bedroom, this plant is unique in its ability to give off oxygen at night. Snake plants are also able to produce enough oxygen in an air⁃sealed room for people to breathe normally. It􀆳s one of the best plants for filtering (过滤) some harmful gases. Water it once a week, being sure to let the soil dry in⁃between waterings, and keep it by a window. Peace Lily If you􀆳re somebody that loves flowers in the house, this is a great option for you. A peace lily produces fragrant flowers all summer long, and effectively removes formaldehyde (甲醛) from the air. It grows best in shady areas and with the soil kept damp. Be careful, though, as this plant can be poisonous if eaten by children or pets. Bamboo Palm This fast growing houseplant looks splendid and is safe for children and pets. It will add damp to the air in the dry winter months and remove indoor air pollutants. It grows well in indirect sunlight away from any cold drafts. Take care of it by keeping the soil wet and misting its leaves. Red Edged Dracaena This drought tolerant plant is good for beginners. It grows well in sunlight. Wipe the underside of the leaves regularly with a damp cloth to make sure it can properly filter your air.Place it in a semi⁃shaded area and mist the soil with room⁃temperature water. Careful, it􀆳s not pet⁃friendly. 　　【语篇解读】　这是一篇应用文。文章介绍了四种可以减少室内污染的植物。 1.How does a snake plant help you? A. It produces enough oxygen. B. It gives off a fragrant smell. C. It keeps the indoor air wet.
