第二节(共5小题;每小题2.5分,满分12.5分)
阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。
Glitter（闪粉）is widely used to decorate clothing, arts, and so on. During festivals and celebrations, it brings joy and excitement, creating a dazzling atmosphere that unites people in the celebration. 16 () It is necessary to know why.
The problem with glitter is that it is a microplastic that doesn't break down naturally. 17() And it makes products that you may normally wish to recycle, such as wrapping paper, no longer recyclable. This is why the UK government has put out guidance on festive waste, reminding households not to put shiny or glittery Christmas cards or wrapping paper in recycling bags.
Besides, due to its size, lots of plastic glitter will unavoidably make its way into water, rivers. and eventually the oceans. 18(). This has been shown to significantly impact the reproduction rates of oysters and make other animals less active, more likely to be eaten and less likely to thrive.
19() Increasing research shows glitter ends up back on our dinner tables. Aside from directly finding its way into our food from glittery cards and decorations, it's consumed by fish, shellfish, seabirds and other marine life, thus passing through the food chain and eventually reaching us and harming our health.
While restricting glitter is only an extremely small step in addressing the broader microplastic problem, the European Union has taken the lead in this. Leading UK retailers such as Morrisons should be praised for taking a stand and going completely glitter free. 20() But if we are to protect our planet, no step is too small.
A. Marine life often mistakes it for food.
B. The glitter you used a decade ago probably still exists.
C. But it is now officially prohibited in the European Union.
D. More and more people are paying attention to food safety.
E. It will take a long time to solve the problem of microplastics.
F. Banning glitter obviously won't completely save the climate or animals.
G. Glitter also contributes to the increasing microplastics inside human bodies.

语篇解读 本文是一篇说明文。文章介绍了闪粉虽在节庆装饰中带来欢乐,但因难降解、污染环境及危害健康等问题,欧盟已限制其使用,并解释了限制的原因。
16. C 根据上文“Glitter(闪粉) is widely used to decorate clothing,arts,and so on.During festivals...celebration.”可知,上文描述闪粉的广泛应用及积极作用,再根据下文“It is necessary to know why.”可知,此处应该是说闪粉现在使用有了限制。故 C 选项“但现在它在欧盟被正式禁止。”能承上启下,符合语境。故选 C。
17. B 根据上文“The problem with glitter is that it is a microplastic that doesn't break down naturally.”可知,本空要围绕其难以分解展开,接下来的句子应该进一步说明这个问题的影响。故 B 选项“你十年前用过的闪粉可能仍然存在。”能承接上文,体现其难以分解、长时间存在的特点,符合语境。故选 B。
18. A 根据上文“Besides,due to its size,lots of plastic glitter will unavoidably make its way into water,rivers and eventually the oceans.”可知,这段描述了闪粉进入水体并最终流入海洋的过程。再根据下文“This has been shown to significantly impact the reproduction rates of oysters.... to thrive.”可知,闪粉对海洋生物产生了显著影响,故本句要表达的是海洋生物经常把它误认为是食物。故 A 选项“海洋生物经常把它误认为食物。”能承上启下,符合语境。故选 A。
19. G 根据下文“Increasing research shows glitter ends up back on our dinner tables.Aside from directly finding...harming our health.”可知,下文详细阐述了闪粉如何通过食物链最终到达人类餐桌并危害健康,因此,本空要说闪粉与人体摄入微塑料的关系。故 G 选项“闪粉也会导致人体内微塑料的增加。”能引出下文,符合语境。故选 G。
20. F 根据上文“While restricting glitter is only an extremely small step in addressing the broader microplastic problem...free.”以及下文“But if we are to protect our planet,no step is too small.”可知,本空要表达禁止闪粉虽作用有限但意义很重大。故 F 选项“禁止闪粉显然不会完全拯救气候或动物。”能承上启下,符合语境。故选 F。
