Sunday is the last day of a week Monday is the first day of a week There is seven days in a week
问题描述：
Sunday is the last day of a week Monday is the first day of a week There is seven days in a week
答
There is seven days in a week "is"改成"are"吧....
答
Sunday is the first day of a week Monday is the second day of a week There are seven days in a week。
按照西方人的习惯把周日成为一个星期的开始，所以把last改为first，把first改为second。there be句型中，后面跟的是复数，所以用are。
答
是改错吧?Sunday is the first day of a week Monday is the second day of a week There is seven days in a week 星期天是一周的第一天；星期一是一周的第二天.一周有七天.( last -> first ; first -> second )...
答
星期日是一星期的最后一天
星期一是一周中的头一天
一个星期有七天
噢，改错啊
前两句没错，There is seven days in a week改为There are seven days in a week
