Answer 1

The tiny village of Frinley / is said(谓) / to possess a cursed tree. 这个句子使用了被动语态。动词say在本句里用法是【say [O] [OC]; [OC]=to do (sth)】(即宾语补足语(复合宾语结构))。 一般say+动词不定式被使用成被动语态。如：It's said that it'll rain tonight./It's said to rain tonight. 然而被动语态中，省略to的不定式动词要恢复不定式符号to，变成be said to do。例：在语法上，根据句子的结构，将/The tiny village of Frinley/划分为主语，后面的不定式/to possess a cursed tree/划分为宾语。又因为实际上是一个小村庄被说成拥有诅咒的树，所以/The tiny village of Frinley/实则是say这个动作的承受者，就作为句子的逻辑宾语。被动语态的句子，当强调动作承受者和动作本身的意义，即主语在句子中没有特殊的实际意义时，时常省略真正的逻辑主语。例：The windows were broken.(强调窗户现在已经被弄破了，而不是强调究竟是谁弄破的。) 句子也可以改写成：It's said that the tiny village of Frinley possecesses a cursed tree. 据说弗林利的小村庄拥有一棵被诅咒的树。（弗林利的小村庄被传言称有一棵被诅咒的树）综上，这是一个被动语态，省略逻辑主语的简单句。
