Jack is a kind boy. He is nine years old and comes from Ohio. He has a special task: to give teddy bears to sick children in the hospital.

Last year, Jack helped make blankets for kids at the hospital. He thought, “What if they also had a teddy bear?” So he began to collect teddy bears. He collected 445 bears last year!

1.1.How old is Jack?

解析：选B。B 细节理解题。题目询问 “Jack 的年龄”，原文第一句明确提到 “He is nine years old and comes from Ohio”（他 9 岁，来自俄亥俄州）。选项 A（8 岁）、C（10 岁）、D（11 岁）均与原文表述的 “nine years old” 不符，因此正确答案为 B。

2.2.Jack made blankets for ________.

A kids at school

B kids in parks

C kids at home

D kids in hospital

解析：选D。D 细节理解题。原文第二段第一句明确说明 “Jack helped make blankets for kids at the hospital”（Jack 帮忙给医院里的孩子制作毯子）。选项 A（学校里的孩子）、B（公园里的孩子）、C（家里的孩子）均未在原文中提及，与原文信息不一致，因此正确答案为 D。

3.3.Why does Jack collect teddy bears?

C To give them to friends.

D To make sick kids happy.

解析：选D。D 细节理解题。原文最后一句提到 “Jack hopes the teddy bears can make sick kids feel braver and happier”（Jack 希望泰迪熊能让生病的孩子变得更勇敢、更开心）。选项 A（卖钱）、B（自己留在家中）、C（送给朋友）均与原文表达的 “帮助生病孩子” 的目的不符，因此正确答案为 D。

4.4.What’s the main idea of the passage?

A Jack loves teddy bears.

B Jack helps sick kids.

C Jack makes blankets.

D Jack has many friends.

解析：选B。B 主旨大意题。文章通篇围绕Jack帮助生病的孩子展开：第一段介绍他给生病孩子送泰迪熊的任务；第二段讲述他去年为医院孩子做毯子，并开始收集泰迪熊；第三段提到他今年的目标以及希望泰迪熊能让生病孩子更勇敢快乐。虽然文章提到了Jack喜欢泰迪熊、做毯子、有朋友帮助等细节，但这些都服务于“帮助生病孩子”这个主题。因此正确答案为 B。
