q宠大乐斗武器觉醒顺序:英语语法

第一次改写正确。
第二次改写错误。可以改成That a child moves the big stone is impossible.或者It is impossible that a child moves the big stone.也可用动名词的复合结构：A child's moving the big stone is impossible.
第三次改写错误。谓语动词没变成第三人称单数形式，而且没有那种用法。

原句：It's impossible for a child to move the big stone.
改写成To move the big stone is impossible for a child. (正确)
或改写成 A child move the big stone is impossible. (错误,应该为:
That a child moves the big stone is impossible.)
又改写成 A child move the big stone to be impossible. (错误,不是句子是短语)

A child move the big stone is impossible.A child move the big stone to be impossible.错，To move the big stone is impossible for a child.对。

To move the big stone is impossible for a child. 正确

A child move the big stone is impossible. 错误,一句句子不能同时有两个做谓语的词,可以考虑改为As a child,moving the big stone is impossible.

A child move the big stone to be impossible. 同样错误,这句错的蛮离谱的，可以说没有这样的说法．

To move the big stone is impossible for a child. 是正确的
A child move the big stone is impossible. 错了 因为出现了两个动词
is 和 move 英语中一个句子只能出现一个真正的动词既谓语 其余的动词应该是属于从句的
A child move the big stone to be impossible.错了 因为此句没有动词
to be只能算做不定式
