问题补充:
lin tao is the only one of the boys who (is,are) good at swimming此题选is还是 are
答案:
is ,因为这里被the only 修饰
======以下答案可供参考======
供参考答案1:
应该是are, who (is,are) good at swimming是boys的定语,对于 who 来说,它的谓语要和事实保持一致,也就是说, who后的谓语动词有单数也有复数
供参考答案2:
who are good at swimming...
动词形式跟boys...
供参考答案3:
肯定还是is!
记住它是one of ……
其中之一,当然是单数了啊,呵呵!
