It is 2026. Xu Maozhi is a good student from Lianyungang, Jiangsu. In 2025, he was given the honor (荣誉) of “Jiangsu Good Teenager in the New Era”.

Xu is kind and hard-working. He loves birds and nature very much. For seven years, he went to wetlands (湿地) to watch birds. He took many photos and drew many pictures of birds. He also kept careful diaries about what he saw.

1.1. When did Xu start to watch birds?

A In 2019.

B In 2020.

C In 2021.

D In 2022.

解析：选A。A 数字计算题。文章开头提到当前是2026年，第三段第一句指出“For seven years, he went to wetlands to watch birds.”，即徐懋之观鸟的行为已经持续了七年。由此可推算，他大约在2019年开始观鸟（2026 - 7 = 2019）。B选项2020年、C选项2021年、D选项2022年均与七年时长不符，故排除。故选A。

2.2. What did Xu NOT do for birds?

A Take photos.

B Keep diaries.

C Draw pictures.

D Catch birds.

解析：选D。D 细节理解题。文章第三段明确列举了徐懋之为鸟类做的事情：“He took many photos and drew many pictures of birds. He also kept careful diaries about what he saw.”，即拍照、画画和写日记，A、B、C三项均有提及。而D选项“Catch birds（捉鸟）”在文中没有出现，且与徐懋之保护鸟类的行为相悖，因此这是他未做的事情。故选D。

3.3. Xu asks people to _______.

A protect birds

B feed birds

C feed birds

D touch birds

解析：选A。A 细节理解题。文章最后一段首句明确指出“He asks his classmates and neighbors to protect birds.”，即他号召人们保护鸟类。B选项“feed birds（喂鸟）”、C选项“watch birds（观鸟）”和D选项“touch birds（触摸鸟）”均未在文中提及，且与原文“protect birds”直接矛盾或无关，因此选A。

4.4. What is the main idea of the passage?

A A kind teacher.

B A bird lover.

C A beautiful park.

D A lovely bird.

解析：选B。B 主旨大意题。全文围绕徐懋之展开，介绍他热爱自然、长期观鸟并为保护鸟类付出行动的事迹，核心人物是一位喜爱鸟类的青少年。A选项“一位善良的老师”与文中人物身份不符；C选项“一座美丽的公园”和D选项“一只可爱的鸟”均非文章讨论对象，只是背景或局部元素。B选项“一位鸟类爱好者”准确概括了文章主旨。故选B。
