1:There used to be a restaurant around the corner.
2:There will be an exciting football match this Sunday.
3:May you be always happy!
如上 如何解释 1 是因为前有介词to 吗
2因为是将来时吗
3呢

Will you be at home?
Be careful!
一般用于将来时或祈使句中。

what are you going to be when you grow up?

1,2均是there be 结构," 存在,有" 的意思
3中,may是助动词,后接动词原形,YOU ARE HAPPY,ARE 的原形就是be 阿
