◆我和他有些相识。

误：I have some acquaintances with him.

正：I have some acquaintance with him.

析：acquaintance 表示对某人或某事物的认识或了解，是不可数名词，不用复数形式，但有时可用不冠词。如上句也可说成： I have an acquaintance with him. 又如：She has some acquaintance with French.(他懂点法语)。

◆他不是朋友，只是相熟。

误：He is not a friend, only acquaintance.

正：He is not a friend, only an acquaintance.

析：acquaintance 表示“相识的人”、“熟人”，是可数名词。又如：He is an old acquaintance.(他是个老相识)。He has many acquaintances.(他交游很广)。

◆我是在一次晚会上认识她的。

误：I made her acquaintances at a party.

正：I made her acquaintance at a party.

析：make one’s acquaintance(也可说成 make the acquaintance of sb)意为“结识某人”，为固定短语，其中 acquaintance不用复数。
