Common mistakes
The puppy fully grown.The puppy is fully grown.
中文学习者常遗漏系动词“is”，因为中文可以说“小狗完全长大了”，其中“长大了”是动词性短语，不需要系词。但英语中“fully grown”是形容词短语，必须与系动词连用。
He is fully grown up.He is fully grown.
“fully grown”已表示“完全长大”，添加“up”构成“fully grown up”是冗余且不自然的。英语中“grown up”作为形容词时意为“成年的”，但“fully grown”同样正确且简洁。应避免叠加使用。
