fellow students，The foggy weather these days has caused widespread concern about air pollution. __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________That’s all.Thank you!Dear fellow students，The foggy weather these days has caused widespread concern about air pollution.It has brought inconvenience and harm to people such as traffic jams and road accidents.Besides，more people are suffering from throat hurts and even lung cancers.Several reasons lead to air pollution in China.First，too many cars give off waste gas on the street.Second，a lot of fossil fuel is consumed in factories，which produces much carbon dioxide.In addition，the more trees are cut down，the less polluted air can be absorbed.It’s time for us to fight against air pollution.We’d better drive less and choose eco－friendly products.More trees should be planted to absorb poisonous gas in the air.Persuading people to use clean energy can also improve air quality.That’s all.Thank you!……………………………………………………………识记·思考·运用 0202基础自主梳理1．核心单词①_____________ adj.平均的②__________ n. 资料；数据③___________趋势；走向；倾向④______________ n．量；数量⑤__________________
