易错句子The drawer jamed shut and I couldn't open it.
正确表达The drawer jammed shut and I couldn't open it.
jam 是“辅音+元音+辅音”的重读闭音节动词，变过去式/过去分词时要先双写末尾辅音字母 m 再加 -ed，所以是 jammed，不能写成 jamed。同类词如 stop→stopped、plan→planned。

易错句子She jammed all her clothes to the suitcase.
正确表达She jammed all her clothes into the suitcase.
jam 表示“用力把某物塞进某处”时，动作有方向性并强调进入一个封闭空间，必须用 into 引出目的地；to 只表示朝某个点移动，不表示进入内部。汉语“把衣服塞到箱子里”的“到”容易被直译成 to，应改为 into。

表示手指被夹在门（门缝）之间时，介词用 in（也可用 between）；on 只表示接触某物的表面，无法表达“被夹在门与门框之间”。汉语“被门夹了手指”本身不带介词，学习者易按“在门上”误用 on。
