1、用stay作为连系动词和行为动词各组一个词组 2、no+名词中的no怎么解释

1.连系动词：stay happy/healthy 保持快乐/健康；stay up 熬夜/通宵/耸立
行为动词：stay at home 呆在家
2.no视为形容词,修饰后面的名词做定语.
如：There are no students in the classroom.
= There aren't any students in the classroom.
There is no student in the classroom.
= There isn't a student in the classroom.
There is no water in the cup.
= There isn't any water in the cup.
