常见错误

❌ 错误:I locked the door with key.
✓ 正确:I locked the door with a key.

错误在于缺少冠词。在英语中,可数名词如 key 通常需要冠词(a/the)或其他限定词。正确用法应加 a 表示泛指一把钥匙。

❌ 错误:He locked his phone in the drawer for safe.
✓ 正确:He locked his phone in the drawer for safety.

错误在于使用了形容词 safe 而不是名词 safety。for 后面应接名词表示目的,safety 是“安全”的名词形式,而 safe 是形容词。
