试一试: Ms. Chen: Here is one box. Sofia: And here are two ___. (boxes / boxs / box) 答案: boxes — 你想到要加词尾,方向对了,只是 -x 后面要用 -es,不是 -s:box → boxes.
试一试: Sofia: I have one watch. Hiroshi: I have two ___! (watches / watchs / watch) 答案: watches — "Watch" 以 -ch 结尾,所以复数是 -es:watches。(在 s, z, x, ch, sh 后面词尾都用 -es。)
