单选题
A
What first seemed like
a luxury, crawling from bed to computer, B
not worrying about
hair, and clothes and face, C
have become
a form of escape, D
a lack of discipline
.
【正确答案】
C
【答案解析】解析：have become一has become。句意：一起床就上网，无所谓蓬头垢面、衣衫不整，这初看起来像是奢侈的生活方式，现已变成一种逃避，一种缺乏自律的表现。本句的主语是由what引导的主语从句，而crawling from bed…，not worrying…等现在分词短语是对luxury的解释说明，故谓语动词应用单数形式，改have为has。
