25.다음 중 내용상 지칭하는 대상이 다른 하나를 고르시오.1)
When I was a student, I spent many hours in the garden, often taking my homework into our little wooden summer house, or up to the top of my favorite tree. I loved ➀that tree. When the wind blew strongly, ➁it swayed, and I could hear the sound of the leaves. The songs of the birds sounded different up ➂there: clearer and louder. I think I went through all the Tarzan books thirty feet or so ➃above the ground. I was madly in love with the Lord of the Jungle, terribly jealous of his Jane. Dreaming about living in the ➄forest with Tarzan led me to decide to go to Africa, to live with animals and write books about them.
