辨析对比

⚖️易混辨析 · in / on / under 一秒分清
  • in 强调"包在里面":in the box(盒子里)、in the bag(书包里)、in the room(房间里);
  • on 强调"接触表面":on the desk(桌面上)、on the wall(墙上)、on the bed(床上);
  • under 强调"在正下方":under the chair(椅子下)、under the tree(树下);
  • 小口诀:里面 in,上面 on,under 藏在最下边
  • 注意 on the wall(挂在墙上)也用 on——只要"贴着"就是 on!

文化角

英语国家的小朋友特别爱玩"寻宝游戏"(Treasure Hunt):大人把小礼物藏在家里各处,写下线索卡,比如"Look under the sofa!"(看沙发下面!),孩子们照着提示一路找下去,找方位的英语就是这样练出来的。

复活节(Easter)还有著名的"找彩蛋"(Egg Hunt)活动:彩蛋藏 in the grass(草丛里)、under the tree(树下)、on the chair(椅子上),谁的篮子装得最满谁最开心!

易错点

⚠️难点 · 易错点
  1. in / on 混用:书在桌上说 in the desk ❌ → on the desk ✅(桌面上是 on)
  2. 回答丢 It's:Where's the cap? — Under the bed. 口语可以,笔试要写完整:It's under the bed. ✅
  3. the 忘记写:It's under chair. ❌ → It's under the chair. ✅(家具前要加 the)
  4. Where's 后接复数:Where's my books? ❌ → Where are my books? ✅(复数用 are,三年级先记住单数用 is)
