Bob picks up the ball. He throws the ball. Bill catches the ball. Bill throws the ball back. Bob catches the ball. Bob throws the ball to Bill. Bill drops the ball. Bill picks it up. He throws it over Bob's head. Bob runs back. He jumps up. He catches the ball.
鮑勃拾起球。他把球扔了出去。比爾接住球。他把球扔了回去。鮑勃接住球。鮑勃把球扔給比爾。比爾沒接住球。他把球撿起來。他把球扔過鮑勃的頭頂。鮑勃往回跑。他跳起來。他接住了球。 ——譯文來自: yigangham
