Question

【题目】As a _____ boy, Liangliang, crosses the river every school day. but he is not afraid.

A. seven years old B. seven-year-old

C. seven-years-old D. seven-years old

Answer 1

【答案】B

【解析】

句意：作为一个七岁的男孩，亮亮，每天上学都要穿过小河，但是他并不害怕。这里是在名词boy“男孩”前面补充定语，需要使用复合形容词，“...岁的”是“数字-year-old”，所以这里的“七岁的”是seven-year-old，连字符不能省，year后不能加s，故选B。
