There is two pencils and a pen in the box改错

There are two pencils and a pen in the box。
there be 句型中，be的形式要跟距离他最近的名词的单复数一致
所以上句也可变成这样的形式
There isa pen and two pencils in the box

THERE ARE TWO PENCILS AND A PEN IN THE BOX.

there are two pencils and a pen in the box . 主谓一致中的就近原则

There are two pencils and a pen in the box

is-are
there be 就近原则 谓语单复数根据紧跟后面的名词而定 这里是pencils 所以用复数

希望能帮到您

is 改为are因为two pencils有超过一件物品
假如有什么不清楚的请追问吧~

There are tow pencils and a pen in the box.

is 改为 are
后面的主语是two pencils ,所以动词用复数形式.

is- two
there be 句型看后面如果有2个以上的主语，看第一个主语，主语是pencils 复数，所以用are
