Kitty and Ben stayed at home(改为现在进行时)Kitty and Ben_ _ at home.
*Kitty and Ben（are staying)at home.(现在进行时）
这里要用are,复数,and表示并列关系,而且算复数
那么ls为什么会混淆,因为
以下情况主语与谓语之间要求就近原则：
A or B +动词
Either A or B +动词
Neither A nor B +动词
Not only A but also B +动词
其中,动词的单复数要看B这个名词的单复数.如：
Either you or I am wrong.
Neither you nor he is wrong.
以下情况主语与谓语之间要求就远原则：
A with/ besides / but +B + 动词
A together with +B + 动词
A as well as + B +动词
A no less than +B +动词
其中,动词与A主语一致.如：
John as well as you is wrong.
The captain with his men was saved.
Helen no less than her sisters is beautiful.
The bat together with the balls was stolen.
Nobody but John and Helen was absent.
这些都是在网上找的,很多东西都可以自己找找,总结总结!
