【题目】(10分)环境保护
湿地指天然或人工形成的沼泽地等带有静止或流动水体的成片浅水区,还包括在低潮时水深不超过6米的水域。湿地与森林、海洋并称全球三大生态系统,在世界各地分布广泛。它在全球生态平衡中扮演着极其重要的角色,有着“地球之肾”的美名。它也是世界上生产力最高的环境之一,它是生物多样性摇篮。但由于近年来人类的不合理利用导致湿地生态系统出现了严重的危机,因此迫切需要对湿地进行保护、恢厦和重建。
说明湿地变化对环境的不利影响,并提出保护湿地的建议。(10分)
【答案】不利影响:涵养水源能力减弱;小气候变差;植被覆盖率下降;土壤侵蚀加剧;生态平衡破坏;生物栖息地减少;生物种类(数量)减少。(任答四点得4分)
保护措施:建立自然保护区;健全法律法规;法制污染;提高公众保护意识等。(任答三点得6分)
【解析】
试题分析:
湿地具有强大的物质生产功能,蕴藏着丰富的动植物资源,湿地能防洪,改善土壤环境,净化水质,防止污染,调节生态平衡,湿地能蓄水,调节气候和降水,利于水循环,湿地有利于保护生物的多样性。遭破坏后:,生物多样性锐减,水土流失,土壤沙化严重;湿地气候遭到破坏,空气湿度减少,净化空气的能力减低,导致空气污染;蓄水能力降低,不利于防洪和抗旱;生产功能衰退,动植物的生态效益降低。
保护湿地的措施可以从加强湿地生物多样性的保护,建立自然保护区;开展水资源的保护和管理、加强湿地生态治理和污染控制;开展湿地调查、科学研究与宣传教育,提高公众保护意识等;实施了“平垸行洪、退田还湖”的湿地生态恢复新举措等。

【题目】 请认真阅读下列短文,并根据所读内容在文章后表格中的空格里填入一个最恰当的单词。
注意:每个空格只填1个单词。
The back-to-school season is upon us, and once again, parents across the country have loaded their kids’ backpacks up with snack packs and school supplies. It’s a good moment to reflect on what else we should be giving our kids as they head off to school.
American parents are feeling particularly anxious about that question this year. The educational process feels more than ever like a race, one that starts in pre-school and doesn’t end until your child is admitted to the perfect college. Most parents are more worried than they need to be about their children’s grades, test scores and IQ. And what we don’t think about enough is how to help our children build their character—how to help them develop skills like perseverance, optimism, responsibility, and self-control, which together do more to determine success than S.A.T. scores or I.Q.
There is growing evidence that our anxiety about our children’s school performance may actually be holding them back from learning some of these valuable skills. If you’re concerned only with a child’s G.P.A., then you will likely choose to minimize the challenges the child faces in school. With real challenge comes the risk of real failure. And in a competitive academic environment, the idea of failure can be very scary, to students and parents alike.
But experiencing failure is a critical part of building character. Recent research by a team of psychologists found that adults who had experienced little or no failure growing up were actually less happy and confident than those who had experienced a few significant setbacks in childhood. “Overcoming those obstacles,” the researchers assumed, “could teach effective coping skills, help engage social support networks, create a sense of mastery over past adversity, and foster beliefs in the ability to cope successfully in the future.”
By contrast, when we protect our children from every possible failure—when we call their teachers to get an extension on a paper; when we urge them to choose only those subjects they’re good at—we are denying them those same character-building experiences. As the psychologists Madeline Levine and Dan Kindlon have written, that can lead to difficulties in adolescence and young adulthood, when overprotected young people finally confront real problems on their own and don’t know how to overcome them.
In the classroom and outside of it, American parents need to encourage children to take chances, to challenge themselves, to risk failure. In the meantime, giving our kids room to fail may be one of the best ways we can help them succeed.
