文中共有10處語(yǔ)言錯(cuò)誤，每句中最多有兩處。錯(cuò)誤涉及一個(gè)單詞的增加、刪除或修改。
增加：在缺詞處加一個(gè)漏詞符號(hào)（^），并在其下面寫(xiě)出該加的詞。
刪除：把多余的詞用斜線（\）劃掉。
修改：在錯(cuò)的詞下劃一橫線（ ），并在該詞下面寫(xiě)出修改后的詞。
注意：1.每處錯(cuò)誤及修改均僅限一詞;
2.只允許修改10處，多者（從第11處起）不計(jì)分。
I was playing at my cousin house. Since his family was rich than mine, he had more toys than I did. There was one on particular I'd always wanted. I put into my pocket when he wasn't looking. I guessed, even at that age, I would never be able to enjoy to playing with the toy or faced my cousin again; I would always know I'd done something wrong. Late on, my aunt drove me home. When she dropped me off, I pulled out the toy slow and gave it back. She knows what had happened, but she thanked me and ever mentioned it again.
