beijing will _____ a dry day 用have 还是 be?

have

虚指it 在句首时用be
it is a dry day.

have

填be,表示某地方的天气怎样应用be,而不用have.这是固定句型，如Today is a sunny day.

have 注意主语是Beijing

如果是It做主语的话 就应该用be

eg, What's the weather today?
It's sunny.

have

It will be a dry day
Beijing will have a dry day

如果主语是it，则用be
如果主语是beijing,则用have

beijing will be a dry day.
