----My son always goes to school without having ______ breakfast.
----It is ______ unhealthy habit. You must ask him to change it.

A．/; an	B．/; a
C．the; an	D．the; a

Answer 1

A

解析试题分析：句意：--我的儿子一直不吃早饭就去上学。--它是一个不健康的习惯。你必须让他改变。分析：一日三餐前不加冠词；一个健康的习惯，habit是可数名词，一个用不定冠词a/an, 同时unhealthy是以元音音标开头的，因此用不定冠词an.故选 A
考点：考查冠词的用法。
