1．[误] He joined the force when he was 18.
[译] 他18岁那年参军了。
[正] He joined the forces when he was 18.
[注]force的复数forces作“军队”、“兵力”解。又如：Superior forces must be concentrated to destroy the enemy. 必须集中优势兵力歼灭敌人。
2．[误] I'll buy some furnitures for my new house.
[译] 我要为新居买几件家具。
[正] I'll buy some furniture for my new house.
[注] furniture是集合名词，不用复数形式。又如：What style furniture do you have? 你的家具是什么式样的？ My furniture is traditional. 我的家具是老式的。 The carpenter makes modern furniture to sell. 那个木匠制作新式家具出售。如果说“大量家具”，须说 a lot of furniture.

1．[误] Garbages should be dumped into garbage can.
[译]垃圾应倒进垃圾桶内。
2．[误] The alpinists climbed among the rocks as nimbly as a goat.
[译]登山运动员们在岩石间攀登敏捷得像山羊。
