Most people have cake for their 80th birthday. But Betty Kellenberger did something amazing — she made history.

Betty is from the US. She became the oldest woman to hike (徒步旅行) the whole Appalachian Trail (阿巴拉契亚小径). The trail is 3,540 kilometres long. She dreamed of this hike for years. In 2024, she finally started it.

The hike was tough. She even fell and went through bad weather. But she didn’t give up. She finished the trail in 2025.

Betty loved the views and people along the way. Now, she says she’s in the best shape of her life!

1.1.What did Betty do for her 80th birthday?

A She ate a big cake.

B She made history.

C She visited Michigan.

D She bought new shoes.

解析：选B。B细节理解题。文章首段明确提到 “Most people have cake for their 80th birthday. But Betty Kellenberger did something amazing — she made history”，直接说明 Betty 80 岁生日没有像大多数人那样吃蛋糕，而是创造了历史。A 选项与原文 “大多数人” 的行为冲突，C、D 选项在文章中无任何相关表述，均为干扰项。故选 B。

2.2. How long is the Appalachian Trail?

A 3,540 kilometres.

B 5,340 kilometres.

C 3,504 kilometres.

D 4,305 kilometres.

解析：选A。A细节理解题。原文第二段明确给出 “The trail is 3,540 kilometres long”，其中 “the trail” 指代题干中的 “the Appalachian Trail”。B、C、D 选项的数字均与原文表述不一致，属于数字干扰项。故选A。

3.3. The underlined word “tough” means ________.

A easy

B delicious

C difficult

D busy

解析：选C。C词义猜测题。结合后文语境，“She even fell and went through bad weather” 说明徒步过程中出现了摔倒、遭遇恶劣天气等困难，且 “but she didn’t give up” 进一步暗示过程不易，因此 “tough” 应表示 “困难的”。A 选项 “easy”（容易的）与语境相反，B 选项 “delicious”（美味的）、D 选项 “busy”（忙碌的）均与 “徒步” 这一场景无关。故选 C。

4.4. What did Betty love about the hike?

A The nice weather.

B The views and people.

C The good food.

D The long time.

解析：选B。B细节理解题。原文最后一段明确提到 “Betty loved the views and people along the way”，直接对应选项 B。A 选项 “nice weather” 与原文 “went through bad weather” 冲突，C 选项 “good food”、D 选项 “long time” 在文章中无相关提及，均为无关干扰项。故选B。
