(原创)The Chinese Alligator(扬子鳄) National Nature Reserve in Anhui Province has released(放归) 200 Chinese alligators kept in captivity into the wild in 2023, helping to add the number of the wild Chinese alligator in Anhui Province to more than 1,400.
The Chinese alligator is only found in China, where the country has listed it as a first-class key protected wild animal. In order to enlarge the wild alligator numbers and change its “critically endangered” situation, a Chinese Alligator Conservation and Reintroduction Project was passed by the National Forestry Bureau in November 2001. It is one of 15 key rescue projects for wild animals and plants in the country.
From 2003 to 2018, 14 experimental（实验性的） programs were carried out by Anhui Province, releasing 108 Chinese alligators that were fed by humans into the wild. In 2019, based on a systematic study of those experiments, an even larger release plan started, trying to release 1,500 alligators over a five-year period. From 2019 to 2022, 1,300 alligators fed by humans were released.
According to recent field surveys, the number of Chinese alligators in the wild is still growing, the areas where they live become larger and larger, and their population structure is better balanced. Most of those released have adapted to the wild environment and reproduced naturally.
In 2022, a field survey was carried out before that year's Chinese alligators were released and found 698 Chinese alligators, and 26 nests with 602 eggs hatching 372 baby Chinese alligators. According to the most recent survey in 2023, the number of Chinese alligators in the wild in May was about 1,200. In August, after the Chinese alligators were released, the number was about 1,400.

答案
【语篇解读】本文是一篇说明文。文章主要介绍了2023年扬子鳄放归野外和野生扬子鳄的数量保持增长的情况。
1. D 细节理解题。根据第二段“In order to enlarge the wild alligator numbers and change its ‘critically endangered’ situation, a Chinese Alligator Conservation and Reintroduction Project was passed”可知扬子鳄保护与放归自然工程的通过,是为了扩大扬子鳄野外种群,改变其“极度濒危”的状况,即保护扬子鳄。故选D。

2. A 细节理解题。根据第三段“In 2019 ... an even larger release plan started, trying to release 1,500 alligators over a five-year period. From 2019 to 2022, 1,300 alligators fed by humans were released.”可知2019年的放归计划目标是放归1500只扬子鳄,2019年到2022年已经放归了1300只扬子鳄;再根据第一段可知2023年已经放归了200只扬子鳄;因此到目前为止,2019年的放归目标已经达成了,即不需要放归更多的扬子鳄。故选A。
＞＞＞ 数字计算题
3. D 段落大意题。根据第四段的内容可知,野生扬子鳄的数量仍在增加,它们生活的区域越来越大,种群结构更加平衡,大多数被放归的扬子鳄已经适应了野外环境并自然繁殖。由此可知本段主要介绍了实地调查的关于扬子鳄的好消息。故选D。
4. A 推理判断题。根据最后一段“According to the most recent survey in 2023, the number of Chinese alligators in the wild in May was about 1,200. In August, after the Chinese alligators were released, the number was about 1,400.”可知目前野生扬子鳄的数量远远小于放归的扬子鳄的数量加上每年新生的扬子鳄数量,由此可推知有些放归的扬子鳄可能死去了。故选A。

解析
【分析】本题是一篇关于扬子鳄保护的说明文阅读理解，共4道题，分别考查细节理解、数字计算、段落主旨和推理判断能力。解题时，第1题需定位原文中项目通过的目的，对应第二段内容；第2题需提取2019年放归计划的目标数与已放归的总数，判断是否完成计划；第3题需概括第四段的核心内容；第4题需结合最后一段的数据进行逻辑推理，得出合理结论。
【解析】1. 细节理解题：根据第二段“In order to enlarge the wild alligator numbers and change its ‘critically endangered’ situation, a Chinese Alligator Conservation and Reintroduction Project was passed”，可知该项目通过的目的是保护野生扬子鳄，对应选项D。2. 数字计算题：根据第三段，2019年启动的5年放归计划目标为1500只，2019-2022年已放归1300只，结合第一段2023年已放归200只，总放归数为1300+200=1500，已达成计划，无需再放归，故选A。3. 段落大意题：第四段主要讲述野生扬子鳄数量增长、栖息地扩大、种群结构优化，且多数放归个体适应野外环境并自然繁殖，即关于扬子鳄的好消息，对应选项D。4. 推理判断题：根据最后一段，2023年5月野生扬子鳄约1200只，8月放归200只后约1400只，新增数量极少，可推断部分放归的扬子鳄可能死亡，故选A。
