couple作主語時的主謂一致問題

couple表示“夫婦”“夫妻”且用作主語時，謂語動詞可用單數（視為整體，尤其是當有each, every, only one等修飾時）或復數（考慮其個體）。如：

The couple were married last week. 這一對夫婦是上星期結的婚。

Each couple was asked to complete a form. 要求每對夫婦填一張表。

有時語境上不明確強調個體還是整體，則用單數或復數均可：

The couple is [are] spending its [their] honeymoon. 這對新婚夫妻在度蜜月。

另外，couple還可表示“一些”“幾個”，此時表示復數意義，用作主語時，謂語動詞要用復數。如：

我的幾個朋友準備開辦一個旅行社。

誤：A couple of my friends is going to open a travel agency.

正：A couple of my friends are going to open a travel agency.
