2、ology” was 1 around the notion that some aspects of plant behavior could be 2 to intelligence in animals. 3 plants lack brains, the firing of electrical signals in their stems and leaves nonetheless triggered responses that 4 consciousness, researchers previously reported.But such an idea is untrue,

Plant biology is complex and fascinating, but it 5 so greatly from that of animals that so-called 6 of plants intelligence is inconclusive, the authors wrote.Beginning in 2006, some scientists have 7 that plants possess neuron-like cells that interact with hormon

5、s; cells in plants also communicate through electrical signals. 13 , the signaling in a plant is only 14 similar to the firing in a complex animal brain, which is more than “a mass of cells that communicate by electricity,” Taiz said.“For consciousness to evolve, a brain with a threshold 15 of compl
6、exity and capacity is required,” he 16 . “Since plants dont have nervous systems, the 17 that they have consciousness are effectively zero.”And whats so great about consciousness, anyway?

(40 points)Text 1People often complain that plastics are too durable. Water bottles, shopping bags, and other trash litter the plane
11、t, from Mount Everest to the Mariana Trench, because plastics are everywhere and dont break down easily. But some plastic materials change over time. They crack and frizzle. They “weep” out additives. They melt into sludge. All of which creates huge headaches for institutions, such as museums, tryin
12、g to preserve culturally important objects. The variety of plastic objects at risk is dizzying: early radios, avant-garde sculptures, celluloid animation stills from Disney films, the first artificial heart.Certain artifacts are especially vulnerable because some pioneers in plastic art didnt always
13、 know how to mix ingredients properly, says Thea van Oosten, a polymer chemist who, until retiring a few years ago, worked for decades at the Cultural Heritage Agency of the Netherlands. “Its like baking a cake: If you dont have exact amounts, it goes wrong.” she says. “The object you make is alread
14、y a time bomb.”And sometimes, its not the artists fault. In the 1960s, the Italian artist Picro Gilardi began to create hundreds of bright, colorful foam pieces. Those pieces included small beds of roses and other items as well as a few dozen “nature carpets”large rectangles decorated with foam pump
15、kins, cabbages, and watermelons. He wanted viewers to walk around on the carpetswhich meant they had to be durable.Unfortunately, the polyurethane foam he used is inherently unstable. Its especially vulnerable to light damage, and by the mid-1990s, Gilardis pumpkins, roses, and other figures were sp

They infused some with stabilizing and consolidating chemicals.Van Oosten calls those chemicals “sunscreens” because their goal was to prevent further light dam
17、age and rebuild worn polymer fibers. She is proud that several sculptures have even gone on display again, albeit sometimes beneath protective cases.Despite success stories like van Oostens, preservation of plastics will likely get harder. Old objects continue to deteriorate. Worse, biodegradable pl
18、astics designed to disintegrate, are increasingly common.And more is at stake here than individual objects. Joana Lia Ferreira, an assistant professor of conservation and restoration at the nova School of Science and Technology, notes that archaeologists first defined the great material ages of huma

We now live in an age of plastic, she says, “and what we decide to collect today, what we decide to preserve.will have a strong impact on how in the future well be seen.”21.
