文中共有10處語言錯誤,每句中最多有兩處。錯誤涉及一個單詞的增加、刪除或修改。
增加:在缺詞處加一個漏詞符號(^),并在其下面寫出該加的詞。
刪除:把多余的詞用斜線(\)劃掉。
修改:在錯的詞下劃一橫線( ),并在該詞下面寫出修改后的詞。
注意:1.每處錯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.
