请教一道英语题

正如 the man i love is you 我爱的人是你,就不一定非要是the man that i love is you,that 可以省
当你拿不定主意时,就以你最肯定的标准为排除标准,比如 speak to 的to 是一定要有的
不能是i speak u,只能是speak to you

以下是关于关系代词的省略原则

:关系代词有who,whose,whom,which,that等,主要用来引导定语从句,它一方面代表定语从句所修饰的那个名词,另一方面在从句中充当一个成分,如主语,宾语,表语,定语等.

1.关系代词which,whom,who,that在定语从句中作宾语时可以省略。
Here is the man (who/that/whom)you're been looking for.
以下情况不能省略：
（1）在介词+whom与介词+which中，whom,which不能省略。
Do you know any shops nearby in which I can buy flowers?
That is the headmaster with whom my father was talking just now.
注：当介词放在动词后时，which,whom就可以省略。
Who is the man (whom) you talked with just now?
（2）在非限制性定语从句中，作宾语的关系代词也不能省略。
Mr Green,whom you know,is the tallest in our school.
The elephant is like a spear,as anybody can see.
（3）在the same ...as,such...as,as...as,the same...that中，as,that即使作宾语，也不能省略I have bought the same bicycle as you have (bought). (指同类用as)
This is the same book that I read the day before yesterday. (that指同一个)
（4）当由and,but,or等连词连接两个或两个以上的定语从句修饰一个先行词时，第一个关系代词可省，但第二，第三个不可省略。
This is the book (which) I read yesterday and which I find very interesting.
2.当that在从句中作补语时可以省略。
He is not the man (that) he used to be.
She is all (that) a teacher should be.
3.在there be 结构中出现定语从句，或在定语从句中出现there be 时，用作主语的关系代词也可省略。
There is a man downstairs (who) wants to see you.
This is the best dictionary (that) there is in the library.
4.状语的省略
（1）当先行词是reason，而且定语从句中作原因状语时，关系代词可用why,that,也可以省略。
The reason (why/that) he failed was his laziness.
That is the reason (why) I did it.
（2）当先行词是way,且在定语从句中作方式状语时，关系代词可用in which,that,也可以省略。
The way (in which/that) these comrades look at problems is wrong.
That was the way (in which/that) she worked the problem out.
注意：当关系代词在定语从句中作主语时，不省略。
例如：I don't know the way that/ which leads to the top of the mountains.
(3)当先行词是time时，关系代词可用when,that 或省略。
The second time (that) I saw him was in 1980.
I don't know the exact time (when/that) the sports meet will take place.
注意：关系代词作宾语有时也不能省略。

另:关系代词that在从句中作宾语或表语时可省略， 例如：
I've forgotten much of the Latin I once knew.
我过去懂拉丁语，现在大都忘了。
He's changed. He's not the man he was.
他变化很大，已不是过去的他了。

这是定语从句的省略问题。

定语从句中关系词省略的6种情形关系词有时可以省略，但这只限于限制性定语从句中，在非限制性定语从句中，关系词则不可省略。
一、关系代词作宾语时的省略当关系代词who, whom, which和that在定语从句中用作动词宾语或介词位于句末时的介词宾语时，可以省略。如：在定语从句中用作动词宾语或介词位于句末时的介词宾语时，可以省略。如：Is there anything (which) you wanted? 想要什么东西吗? Who is the man (that / who / whom) you were talking to? 刚才和你讲话的人是谁?
二、关系代词作表语时的省略当关系代词that在定语从句中用作表语时，可以省略。如：China is not the country (that) it was. 中国已不是过去的中国了。(that作表语)
三、关系代词作宾补时的省略当关系代词that在定语从句中用作宾语补足时，可以省略。如：I’m not the madman (that) you thought me. 我并不是你所认为的那个疯子。(that作宾语补语)
四、关系副词when的省略用作时间状语的关系副词when通常不能省略，但有一种特殊情况，即用于day, year, time等少数几个词后时可以省略(也可换成that)也可换成。如：That was the year (that) I first went abroad. 就是那一年我第一次出国了。I’ll never forget the day (that) we met. 我永远也忘不了我们见面的那一天。
五、关系副词where的省略用作地点状语的关系副词where通常不能省略，但有一种特殊情况，即用于place, somewhere, anywhere, everywhere, nowhere少数几个词后时可以省略(也可换成that)。如：This is the place (where) they met yesterday. 这就是他们昨天碰头的地方。Have you somewhere (that) I can lie down for an hour? 你有没有一个什么地方可以让我躺一个小时？
六、关系副词why的省略关系副词why通常只用于the reason后引导定语从句，且通常可换成that或for which，均可省略。如：That’s the reason (why, for which, that) he came.
这就是他来的原因。
Give me one reason (why) we should help you. 给我举出一个我们应当帮助你的理由。 absent, nothing couldn’t be done. 由于他缺席，什么事也干不成。

C.I spoke to
关系代词由于在定语从句中是作介词TO的宾语,因此可以省略.

关系代词在定语从句中作宾语可以省略掉。这里，关系代词who, that, whom都可以做speak to 的宾语。但关系代词在定语从句中作主语就不可以省略掉了。

一般来说关系代词像that who whom都可省略
