Question

【题目】指出下列句中主语的中心词

【1】The teacher with two of his students is walking into the classroom.

【2】There is an old man coming here.

【3】The useful dictionary was given by my mother last year.

Answer 1

【答案】

【1】teacher

【2】man

【3】dictionary

【解析】

【1】句意：老师和他的两个学生正在走进教室。with two of his students是介词词组，作伴随状语；The teacher是主语；is walking into是谓语动词，做谓语； the classroom是句子宾语。此句也可这样表达：The teacher is walking into the classroom with two of his students. The teacher是主语，the特指，修饰teacher，故主语的中心词是teacher。

【2】句意：有一位老人来这里。there be 是一种固定句型，be动词后面的名词即为主语。故本句的主语是an old man，an old是修饰man的，故主语中心词是man。

【3】句意：这本有用的词典是我母亲去年给我的。The useful dictionary是句子的主语； was given 谓语动词，做句子的谓语；by my mother 是方式状语，last year是时间状语。主语中the useful是修饰dictionary，故主语中心词是dictionary。
