The windows and doors come from old buildings around her town that were pulled down. The top of the house is an old boat turned upside down. And the gate in front of her house is made of rocks and old glass bottles. Amy recently won a prize from the Help Save Our Planet Society. The president said, Amy is an inspiration to us all.”

Read the third paragraph
Amy isn’t the only one who is good at recycling. Jessica Wong from Hong Kong uses old clothes that people don’t wear anymore to make bags. She has been doing this for a few years now. She opened a small shop where she sells her bags, and she has also set up a website to sell them online. She especially likes to use old jeans to make handbags. Her bags are cute and useful. “I plan to write a book about new ways to use old clothes,” she said. “I hope people can read my book and enjoy it!”
该句中，who is good at recycling 是定语从句，修饰先行词 the only one。先行词指人，因此引导词用 who。
注意：当先行词 one 指物时，定语从句只能用 that 而不用 which 引导。
e.g. My photos are not well kept. This is the only one that I found in the case. 我的照片没有保存好，这是我在箱子里找到的唯一一张照片。
set up 意为“开办，建立”，常和表示组织、机构、团体等意义的名词连用，这时与 found 的意义基本相同，但 set up 侧重于“开始”，found 更着重打基础
found 意为“创立；创建” ，侧重打下基础或创办，一般指兴建城市，建立国家、党派或创办大学等
build 意为“建筑；建造”，指施工建筑，如房屋、桥梁、道路等的建造
put up 着重指建造或搭起一个具有高度的、具体的物体
