Question

The boy over there is the only one of the students who ________ to Europe．

[　　]

A．has been

B．have been

C．has gone

D．have gone

Answer 1

答案：A
解析：

思路解析：over there说明the boy就在眼前，因此排除C、D两项；先行词是the only one of the students，是一个人，因此答案是A项。 　　绿色通道：要熟记各种学过的词汇、句型。可以简单地记为：“one of the＋可数名词复数”作先行词时，定语从句谓语动词用复数；“the only one of ＋可数名词复数”作先行词时，定语从句谓语动词用单数。
