问题描述：
She was so terribly ill that she had to ask for ________________.
A.a three day leave B.three-days sick leaves
C.a sick leave of three days D.three-day sick leaves
答
答案选择c
A答案应该改成 a three-day leave
B答案应该把three-days中间的连字符去掉就对了
D答案应该添加一个冠词a就行了
答
C。three day做定语加连字符，leave作假期讲不管几天只要是请一次就是单数
答
A.three 和 day 一起时,除非加连词符,否则是不会出现名词用单数形式的情况的.
B.量词和名词由连词符连接作定语时,一定是单数形式,且病假无论几天都是一次病假,所以就是 a three-day sick leave
D.参见 B

答
C三天病假
全文是大概意思是：她的病如此严重，她必须请三天的病假
A 三天
B three-days 中间的横杠应该去掉
D day后面应该加s 并且也要把中间的横杠去掉
