This pair of shoes ( ) very expensive 括號里該填 is 還是 are

題目：

This pair of shoes ( ) very expensive 括號里該填 is 還是 are

解答：

這是一個經典語法問題,在英美加澳等國都沒有一個肯定的答案.
英美人說話有一個叫做「就近原則」,說的是在選擇單複數搭配上,根據最近的詞來決定.尤其是在日常口語交往中是這樣.
上面一句在口語中,你極有可能聽到 This pair of shoes are very expensive,和 There is a pair of very expensive shoes.
但在語法考試中,This pair of shoes is very expensive.
也就是說,知道 This pair of shoes are very expensive 不能算錯,但在考試中還是應該答 This pair of shoes is very expensive.
