注意：在“one of + 名词复数 + 定语从句”结构中，定语从句的谓语动词一般用第三人称复数形式，但当one前面有the, the very, the less, the only或形容词最高级修饰时，定语从句的谓语动词一般用第三人称单数形式，如：

(1) Li Lei is one of the students who are good at English. 李蕾是英语学得好的学生之一。

(2) Alice is the only one of the girls that is from America. 艾利斯是唯一的一个来美国的女孩。

E．there be结构中be动词的形式由紧接近be后面的名词的形式所决定。如：

(1) There is a teacher and seventy students in the classroom. 教室里有一个老师和七十个学生。

(2) There are seventy students and a teacher in the classroom. 教室里有七十个学生和一个老师。

F．在某些虚拟语气的句子中，无论主语是谁，be动词总是为were的形式。如：

(1) If I were a bird, I would fly in the sky freely. 要是我是一只鸟，我将自由自在地在天空飞翔。

(2) If he were here, I would talk to him face to face. 如果他在这里，我将面对面地跟他谈。
