Plastics are ubiquitous.Their role as a cost-effective, chemically stable, versatile multipurpose material precluded early attempts to regulate plastic wastes and facilitated the, now widespread, planetary contamination.Left to slow UV decay and thermooxidative weathering, large plastics chip away into less than 5 mm fragments, or microplastics, which, in turn, can degrade further into nanoplastics.In the manufacturing process, several components, such as catalysts, solvents, stabilizers, flame-retardants or pigments, can be added to the nascent plastic polymers.During the plastic break down, these additives, some of which act as disruptors of endocrine pathways, may liberate to the surrounding medium, worsening the effects of plastic pollution [1].All this wear and tear provide attachment surfaces for microorganisms, including pathogens, enhances the incorporation of plastic fragments into marine and terrestrial food webs, and, once bioaccumulated, may impair endogenous endocrine and neuroimmune crosstalk in vertebrates and invertebrates (Fig.1).

初中正是帮助学生打好基础的关键时期,“听说读写”作为英语学习的四项基本内容,许多教师往往只注重了“听读写”这三项,却忽视了“说”这一重要内容。英语作为一门语言学科,我们学习的最终目的便是能够在生活中熟练应用,学会用英语表达。因此,基于这一思想,教师在进行英语教学时要及时采用适当的教学策略,丰富课堂活动,让学生在英语课堂上将英语大声的说出来,真正培养学生的英语口语表达能力,使之全面发展。 一、听读
