易错句子I collected many beautiful shell on the beach.
正确表达I collected many beautiful shells on the beach.
shell 是可数名词，前面有 many 时必须用复数 shells。汉语名词不随数量改变形式（“很多漂亮的贝壳”），因此学习者容易漏掉复数词尾 -s。

易错句子The turtle hides inside shell when it is scared.
正确表达The turtle hides inside its shell when it is scared.
可数名词单数前必须有冠词或限定词；这里指乌龟自己的壳，用物主限定词 its 最自然。汉语说“躲进壳里”不必加限定词，所以容易漏掉 its。
