高一英语 定语从句

Question

大家帮帮我改错句哈 还有为什么那么改
There seem to be a knife and folk on the table.
The students in our school each has known the meaning ot WTO.
It were Tom and John who played a trick on the old man.
Thank you !!!

Answer 1

1. seems因为这是there be 句型，seem的形式要取决于后面的名词，在这个句子中，名词是a knife and fork,它表示的是一套刀叉，是一件东西，所以是单数。
2. has改成have。因为主语是The students，是复数形式，所以谓语动词要用原形。
3. were改成was，因为这是一个强调句型，主语是it，it后只能用was，不能用were。

Answer 2

1.seem__seems ，这是there...be句型
2 each__every ,every 可以做主语，each不可以
3 who __that ,这是一个强调句。

Answer 3

There seem（seems) to be a knife and folk on the table.
The students in our school each has(have) known the meaning ot(of) WTO.
It were (was)Tom and John who(that) played a trick on the old man.
括号中是正确的
