On February 20, 2026, a courtroom (法庭) became full of joy and tears. An 11-year-old boy named Cain Coles was adopted (被收养) by Vandria and Tyrone Johnson. He had been in foster  care for two years, and now he finally had a forever family.

That day was more than just a special day for the law. About 45 of Cain’s fifth-grade classmates came to support him. They wanted to stand by their friend on this special day. Around 100 family members and friends also joined the ceremony. Judge Robert Wilson completed the adoption and allowed Cain to change his name to Alexander Kaine Johnson.

Adoption experts said the boy gets along very well with his new family. His new parents described him as kind, helpful and polite. He has grown and changed a lot since they first met him. They are very proud of how much he has grown up.

Cain felt thankful to his family and friends. The judge praised the family for their love and patience. In the end, the boy left the court with a new name, a warm family and the support of his whole community. It was a really unforgettable day for him, and he looked forward to his new happy life.

1.1.What do we know about Cain before February 20, 2026?

A He had a new family.

B He lived in foster care.

C He was 12 years old.

D He had no friends.

解析：选B。B细节理解题。根据第一段第三句“He had been in foster care for two years”（他已经在寄养家庭生活了两年），可以直接锁定他此前的状态是处于寄养中，因此选项B正确。选项A“He had a new family”是发生在当天收养仪式之后的事情，并非之前；选项C“He was 12 years old”与原文第一段“An 11-year-old boy”不符；选项D“He had no friends”属于过度推断，文中不仅未提及他没有朋友，反而提到有45名同学前来支持他，因此D项错误。故选B。

2.2. Why did Cain’s classmates go to the courtroom?

A To meet the judge.

B To support Cain.

C To change their names.

D To join the experts.

解析：选B。B细节理解题。第二段第二句明确交代：“They wanted to stand by their friend on this special day.”（他们想在这个特殊的日子支持他们的朋友。）文中的“stand by”与选项中的“support”语义一致，因此B项正确。选项A“见法官”虽在文中提及法官出席，但并非同学们到场的动机；选项C“改名字”是Cain的权利，与同学无关；选项D“加入专家行列”在文中并未提及同学们与专家有任何互动，故排除。故选B。

3.3. What did Cain’s new parents think of him?

A He felt sad at home.

B He often caused trouble.

C He disliked his school.

D He was kind and polite.

解析：选D。D细节理解题。题干中的关键信息是“new parents think of him”，对应第三段第二句“His new parents described him as kind, helpful and polite.”（他的新父母形容他善良、乐于助人且有礼貌。）这是父母对孩子的直接正面描述，选项D完全吻合原文。选项A“在家感到悲伤”与原文中“gets along very well”及父母的骄傲情绪相悖；选项B“经常惹麻烦”与文中的“kind, helpful, polite”完全相反；选项C“不喜欢学校”属于无中生有，文章未涉及他对学校的负面情绪。故选D。

4.4. Why did the judge praise the Johnsons?

A They showed love and patience.

B They were rich and famous.

C They knew the judge well.

D They came with many friends.

解析：选A。A 细节理解题。根据第四段第二句“The judge praised the family for their love and patience.”（法官称赞了这一家人所展现的爱与耐心。），可知A项为原文的同义复现。选项B“他们富有且出名”在文中完全没有提及；选项C“他们和法官很熟”属主观臆断，原文强调的是收养行为本身的法律与情感意义；选项D“他们带了很多朋友来”虽在文中有描述（约100名亲友到场），但这并非法官表扬他们的直接原因，属于次要细节干扰。故选A。

5.5. What is the story mainly about?

A A boy’s school life.

B A strict court activity.

C A warm adoption day.

D A judge’s hard work.

解析：选C。C 主旨大意题。文章开篇点明时间地点，随后详细描述了一名寄养儿童被正式收养的全过程，包括同学支持、父母评价以及法官的祝福，全文基调温馨感人。通篇围绕收养仪式的喜悦与归属感展开，选项C“一场温暖的收养日”准确概括了文章的核心事件与情感色彩。选项A“男孩的学校生活”范围过大，且未突出收养这一核心事件；选项B“一场严肃的法庭活动”与文中“full of joy and tears”及“unforgettable day”的温馨氛围相冲突；选项D“法官的辛勤工作”仅是文中提及的一个侧面细节，不足以概括全文主旨。故选C。
