Amber: a time capsule (胶囊) of life
Amber is a kind of fossilised(石化的) tree resin(树脂). It often traps small plants or animals, keeping them in almost perfect condition for millions of years. This makes amber a valuable "time capsule" for scientists.
In 2016, a piece of amber from Myanmar surprised the world: It held the tail of a dinosaur. The tail had feathers—and this changed scientists' old ideas, because they once thought dinosaurs had no feathers at all. Another piece of amber from Northern Europe held a flower that doesn't exist anymore. By studying it, scientists found out that the area's climate was warmer 35 million years ago.
Amber also helps scientists discover new species. A piece of African amber showed 13 new kinds of ants. Before this discovery, scientists thought ants came from the northern half of the earth. This finding told us that ants spread earlier and to more places than we thought.
Although we've learned a lot from amber, it still has many secrets. With more research, it will keep teaching us about the past.
1. The underlined word "traps" in Paragraph 1 probably means "
A. 保护 B. 伤害 C. 培育 D. 困住
2. What did the 2016 Myanmar amber show?
A. Dinosaurs had no feathers.
B. Some dinosaurs had feathers.
C. Ants lived in Africa millions of years ago.
D. Europe was much colder in the past.
3. Why is the African amber important?
A. Because it has helped scientists discover 13 new ant species.
B. Because it has helped scientists know ants came from the northern half of the earth.
C. Because it has proved ants spread later than scientists thought.
D. Because it holds a kind of flower that no longer exists.
4. What is the passage mainly about?
A. How amber forms naturally.
B. Where amber is usually found around the world.
C. Why amber is a valuable "time capsule" for scientists.
D. When amber was first discovered by scientists.

解析
【分析】
本题为英语阅读理解题，包含词义猜测、细节理解、主旨大意三类核心题型。解题思路如下：
1. 第1题是词义猜测题，需结合上下文语境，明确“traps”在描述琥珀与小动植物关系中的含义；
2. 第2、3题是细节理解题，需定位原文对应段落，提取题目问题的关键信息；
3. 第4题是主旨大意题，需梳理全文内容，归纳核心主题。
【解析】
1. 第1题：根据第一段“Amber is a kind of fossilised tree resin. It often traps small plants or animals, keeping them in almost perfect condition...”可知，琥珀作为石化树脂，会“困住”小动植物并将其保存，因此“traps”的中文意思是“困住”，选D。
2. 第2题：根据第二段“In 2016, a piece of amber from Myanmar... held the tail of a dinosaur. The tail had feathers—and this changed scientists' old ideas, because they once thought dinosaurs had no feathers at all.”可知，2016年缅甸琥珀显示恐龙有羽毛，选B。
3. 第3题：根据第三段“A piece of African amber showed 13 new kinds of ants... This finding told us that ants spread earlier...”可知，非洲琥珀帮助科学家发现13种新蚂蚁，选A。
4. 第4题：全文围绕琥珀作为“time capsule”的价值展开，介绍了琥珀在研究恐龙、古气候、物种等方面的作用，核心是说明琥珀对科学家的重要性，选C。
