语法点:被动报道结构 It is said that / be said to (Passive Reporting)
当我们转述“人们说、大家认为、据报道”这类信息,但不想或不必说明是谁说的时,就用被动报道结构。它有两种形式:一是 It is said that + 从句,用 it 作形式主语;二是把从句的主语提前,变成 主语 + be said to + 动词原形(如果说的事发生在更早,用 to have done)。常用于 say, believe, think, know, report, expect 等动词。本课开头的 is said to possess 和 It is said that 就是这两种形式的典型例子。
结构
| 形式 | 结构 | 例子 |
|---|---|---|
| it 形式主语 | It is said / believed / thought that + 从句 | It is said that the tree is cursed. |
| 主语提前 | 主语 + is said / believed to + 动词原形 | The tree is said to be cursed. |
| 表示更早的事 | 主语 + is said to have + 过去分词 | The tree is said to have claimed many victims. |
| 过去时 | It was said that … / 主语 + was said to … | It was said that the tree would bring bad luck. |
| 否定 | It is not said that … / 主语 + is not said to … | The tree is not said to be dangerous. |
课文中的例句
- [句 1] The tiny village of Frinley is said to possess a 'cursed tree'. — 主语 + is said to + 动词原形,主语提前的被动报道形式
- [句 4] It is said that if anyone touches the tree, he will have bad luck… — It is said that + 从句,it 作形式主语
- [句 5] Many villagers believe that the tree has already claimed a number of victims. — 主动形式,可改写为 The tree is believed to have claimed…
- [句 8] In spite of all that has been said, the tourists have been picking leaves… — has been said 是 say 的现在完成时被动形式,同样不说明谁说的
补充例句
- The old church is said to be five hundred years old. 据说这座老教堂有五百年历史了。
- It is believed that the vicar will never cut down the tree. 人们相信牧师永远不会砍掉那棵树。
- The tourist is reported to have picked a leaf from the tree. 据报道那位游客从树上摘了一片叶子。
易错点
- ❌ It is said the tree possesses bad luck by people. → ✅ It is said that the tree possesses bad luck. 用了被动报道就不必再加 by people。
- ❌ The tree is said that it is cursed. → ✅ The tree is said to be cursed. / It is said that the tree is cursed. 主语提前后要用 to do,不能再接 that 从句。
- ❌ The tree is said to claim many victims last year. → ✅ The tree is said to have claimed many victims last year. 说的事发生在更早,要用 to have done。
- ❌ People is said that the tree is cursed. → ✅ It is said that the tree is cursed. that 从句形式的主语只能是 it。
