一、Ella 对植物特别感兴趣，她去了植物园。请阅读短文，用方框中所给单词的最高级填空。每个单词限用一次。
clean popular colourful
helpful dirty good big
The lotus is one of the most meaningful flowers in Chinese culture. People love it because it grows in dirty water but still looks beautiful. This flower shows two important ideas: staying clean and being strong. Let's learn why the lotus is so special!
In Chinese stories, the lotus is called 1. flower. For example, in the movie Ne Zha 2, Ne Zha's body comes from lotus roots(根). This tells us the lotus is magical and can bring new life.
The lotus grows in 2. places—like muddy ponds(池塘) and swamps(沼泽). Its roots are in dirty mud(泥土), but its flowers rise above the water and stay clean. This makes it 3. example of never giving up, even when life is difficult.
People also use the lotus in festivals and cooking. During 4. holidays, like Chinese New Year, families eat lotus root dishes for good luck. A famous dish, Honghu
lotus root soup, is now one of 5. dishes at many restaurants.
Artists and scientists both love the lotus. It appears in 6. paintings because of its pretty leaves and pink flowers. Scientists also say it's one of 7. plants because it can clean dirty water.

1. the cleanest
2. the dirtiest
3. the best
4. the biggest
5. the most popular
6. the most colourful
7. the most helpful

二、Ella 在植物园看到了捕蝇草。请阅读短文,根据短文内容从每小题所给的 A、B、C、D 四个选项中选出最佳选项。
The Venus flytrap(捕蝇草) is a meat-eating plant growing in a small area of North Carolina and South Carolina in the United States. While most plants get their "food" from the soil(土壤), this clever hunter uses special leaves to catch insects. Each leaf acts like a tiny green mouth with special hairs.
When an insect touches one of the hairs, the leaf is triggered(触发), but it does not close right away. However, if the insect touches a second hair within 20 seconds, the leaf closes quickly and traps the insect inside. This "double-touch rule" stops the plant from wasting energy on things like raindrops(雨滴). Once the leaf closes, the insect's continued movements trigger more hairs, and the plant starts to digest(消化) the insect.
The Venus flytrap does not need to eat insects very often. In fact, it can live for weeks without food as long as it gets enough sunlight. On average, it catches two to three insects every month. These meals help the plant grow, much like a bear living off a few large fish.
▲ A survey by the North Carolina Natural Heritage Program in 2019 found 163,951 Venus flytraps in North Carolina and 4,876 in South Carolina. This marked a 96% drop compared with 4.5 million in 1979. By 2016, the plant could only be found in the wild in 71 places. However, only 20 of these places were considered(认为) healthy enough for the plant to grow.
The Venus flytrap shows us how creative nature can be. It is not just a plant—it is a smart hunter too!
1. What does the "double-touch rule" help the Venus flytrap do? ()
A. Grow better in the sun.
B. Catch more small insects.
C. Wait for the right time to start digesting insects.
D. Stop the plant from wasting energy on useless things.
2. Which of the following would be the best to fill in "▲" in Paragraph 4? ()
A. Where can people find the plant?
B. Sadly, this amazing plant is now in danger.
C. How many Venus flytraps are there in the world?
D. Scientists are interested in this amazing plant.
3. 提升题 What would be the best title for the passage? ()
A. Ways to Protect the Venus Flytrap
B. The Good Points of the Venus Flytrap
C. Some Facts About an Amazing Plant
D. Reasons Why the Venus Flytrap Is Amazing

1. D
2. B
3. C

【分析】
1. 第1题是细节理解题，先定位题干关键词“double-touch rule”，找到原文对应描述，匹配选项即可；
2. 第2题是句子还原题，分析第四段核心内容（捕蝇草数量锐减、濒危），选择能引出该内容的过渡句；
3. 第3题是主旨大意题，梳理全文各段内容，归纳核心主题，排除片面选项。
【解析】
1. 细节理解题：根据短文第二段最后一句“This 'double-touch rule' stops the plant from wasting energy on things like raindrops”，可知该规则帮助捕蝇草避免将能量浪费在无用事物上，对应选项D。
2. 句子还原题：第四段主要讲述捕蝇草数量大幅下降（从1979年的450万株降至2019年的约17万株），野生生长地仅71处且仅20处健康，说明其处于濒危状态，因此开头需引出这一现状，选项B符合逻辑。
3. 主旨大意题：全文介绍了捕蝇草的捕食特性、生存方式、数量现状等事实，选项C最能概括全文；A未涉及保护方法，B仅讲优点不全面，D仅讲原因不全面，故排除。
【答案】
1.D 2.B 3.C
【知识点】
英语阅读；细节理解；主旨大意
【点评】
本题为英语阅读理解题，围绕捕蝇草展开，考查学生对原文细节的查找、段落逻辑的把握及文章主旨的归纳能力，需学生仔细阅读原文，准确提取信息。
