There _____ a class meeting next week

呵呵,这是There be句型.
There be表示某地存在某物,
have表示某人或某东西拥有某物,例如
_____ a car over there.应用there be,因为是over there,它表示地点
He _____ a car.应用has,因为He是人
同样,如果是The company _____ a car.也应用has
there will be 是there be的一般将来时
还有there will be
there have/has been
there had been
there would be 等等
