Question

【题目】— How many boys and girls are there under the tree? — There a boy and three girls.

A. are B. is C. has D. have

Answer 1

【答案】B

【解析】

句意：-树下面有多少男孩和女孩？-有一个男孩和三个女孩。are是，主语为复数；is主语为单数；has有，第三人称单数形式；have有，动词原形。这句话考查的是there be句型，表示“有…”，故先排除C和D。be动词用单数或复数应与离它最近的名词一致，即就近原则，空后a boy离be更近，故应用单数，选B。
