On a sunny autumn day, teenagers and their parents were busy harvesting corn and sweet potatoes in Tianjin.

Yunyao is a 17-year-old autistic (自闭症的) boy. He smiled shyly while shucking corn. “We ate the corn we grew ourselves. It’s very delicious,” he said.

This farm is called Hui’ai Farm. It means “a farm that collects love”. Eight families set it up. All these families have autistic or intellectually disabled children. Yunyao’s father, Zhu Xijun, is one of the founders (创建者). He was a lawyer before, but now he works on the farm every day. “I don’t need the farm to make money. The children are beyond the age for going to school. They need something to do,” he said.

Guan Xiaoyan is another founder. Her 17-year-old son is also autistic. The boy used to be quiet. But now he is outgoing because of the farm work. “He learned teamwork. He has healthy habits now. He is willing to play with others,” Guan said.

1.1. What were the people doing on the sunny autumn day?

A Planting corn and sweet potatoes.

B Picking corn and sweet potatoes.

C Selling corn and sweet potatoes.

D Eating corn and sweet potatoes.

解析：选B。B 细节理解题。农业语境下特指“收割”或“收获”庄稼。选项B中的“picking”虽常指“采摘”水果，但在此处广义上可理解为“采收”，与原文的“harvesting”含义相符，是对原文动作的正确同义转述。故选B。

2.2. What can we know about the corn according to Yunyao?

A It was given by his friends.

B It was grown by the farm.

C It was bought from a shop.

D It was cooked by his mom.

解析：选B。B细节理解题。原文第二句中云尧说“We ate the corn we grew ourselves”，而他在农场劳作，因此玉米是他们农场的人一起种的。故选B。

3.3. What did Zhu Xijun do before?

A He was a farmer.

B He was a teacher.

C He was a lawyer.

D He was a doctor.

解析：选C。C细节理解题。原文第三段明确提到“He was a lawyer before”，朱溪君以前的职业是律师。故选C。

4.4. After working on the farm, Guan’s son ________.

A became quieter

B liked staying outside

C liked working alone

D became outgoing

解析：选D。D细节理解题。原文第四段提到关女士的儿子“used to be quiet. But now he is outgoing because of the farm work”。故选D。

5.5. What can we know from the passage?

A Farm work helps autistic youths.

B Some special gifts for autistic youths.

C Special farms make lots of money.

D Autistic youths made new friends.

解析：选A。A 主旨大意题。文章通过云尧和关女士儿子等例子，具体展现了自闭症青少年在农场劳动后变得开朗、学会合作等积极变化，核心是阐述农场工作对他们的帮助。选项C“特殊农场赚很多钱”与文中朱溪君所言“我不需要农场赚钱”相悖。选项D“交新朋友”属于过度推断，原文仅提到关女士的儿子“愿意和别人玩”，并未明确提及他或其他人因此结交了新朋友。故选A。
