课时作业三　阅读理解提分练3 　　　　　　　　　　　 Passage 1 (2023·山东潍坊·模拟预测) This 3­mile stretch of sand and tide pools beneath a castle of 80­foot cliffs is a California tourism poster if there ever was one. Nothing disturbs the perfect, sunny view, except—once you're aware of them—microplastic particles (颗粒). But you have to look close­on­your­hands­and­knees close­to see one. And once you do, you see another and another—so many that you may not think of this, or any beach, the same way again. These tiny preproduction plastic balls that manufacturers (生产商) melt down to form everything have been escaping factories, container ships, trains, trucks—and public notice—for decades. The 2­to 3­millimeter, multicolored balls are a subset (子集) of microplastic—plastic particles less than 5 millimeters in size. Microplastic particles accumulate where water takes them, and they've been found on shorelines of every continent. Dr McReynolds is an environmental scientist who's now joined a global movement studying their trail into the environment. Establishing a baseline count of the presence of microplastic particles—and, more broadly, any microplastics—is the focus of Dr McReynolds' scientific study here. Charting the count, noting tide, current, and weather conditions will show if amounts are increasing, and perhaps at what rate and why. That knowledge, he says, can inform solutions to plastic pollution such as regulation of their use. “What are you doing? Picking up trash？” asks a steady stream of beach walkers whenever Dr McReynolds' crew walks onto the beach and sets up equipment. These are teachable moments for Dr McReynolds. One recent morning he told some beach walkers how microplastic particles are believed to absorb toxic chemicals, and—because they resemble fish eggs—are eaten by fish and birds and enter the food chain. Almost right on time, a seagull hopped up to a plastic­coated photo of microplastic particles and hungrily pecked (啄食) at it. Will his work help save the world? Dr McReyn
