【定向求助,其他人恐怕很难总结出了.不求其他知道网友回答】不定式和谓语动作的时间.
今天可能有点晚了.我稍微举几个方面的例子【摘抄自《张道真英语语法大全》.看懵了】：
【1】不定式表示的时间通常和同句谓语动词表示的时间相同：
He seemed to study English.=It seemed that he studied English.
He seemed to be studying english.=It seemed that he was studing English.
I shall do something to assist him.
【2】不定式完成式的时间糟于谓语动词表示的时间.
【3】谓语动词表示希望、决定等,不定式表示的时间晚于谓语.
I‘m sorry to have disturbed you I'm sorry to disturb you.
第一句的意思是说：我很抱歉打扰了你.是表示事情已经发生了.而第二句是说：我很抱歉来打扰你,事情还没有发生.
【4】过去时谓语动词的不定式用【完成时态】,表示过去未实现的愿望：【不太懂】
he hoped to have studied English.
Why didn't you give me a ring?Well,I meant ( ) ,but later i forgot.
have telephoned
He was impatient to have finished the job.
那本语法书列出了以上四点.以下有句子资源,可以你在解答时用：
I am sorry to have lost your key.
I remember to have senn her.
He was reported to have died.
I don‘t want to see anyone.
You had better to be leaving.
He is prudent enough to do so.
To have studied English at least six years is the qulification for this position.

Answer 1

不定式有三种表示时间的形式：一般式 to do,完成式 to have done,进行式 to be doing

一、一般式 to do 所发生的时间与谓语动词在逻辑上通常有三种关系,或者同步发生,或者相继发生,或者随后发生.

   1、如果谓语动词表示的是一种表象,如seem, appear, happen, turn out, prove 等,或本身就是将来时,那么to do 的时间与谓语动词同步.如：

He seemed to study English. (= It seemed that he studied English.)

I happened to come across him yesterday (=It happened that I cameacross him yesterday. )我碰巧遇到了他.

The rookie turned out to be the best hitter on the team. (= Itturned out that the rookie was the best hitter on the team. ) 新手证明是队里最出色的击球员.

I shall do something to assist him. (=I shall do something so that Ican assist him )

He will come to see you tomorrow. (=He will come so that he can seeyou tomorrow)

   2、如果谓语表示情感状态的系表结构,那么 to do 的时间与谓语状态相继发生,即 to do还没有结束,主句的状态就发生了.如：

He is prudent enough to do so. (He is prudent enough that he should doso.)

I'm sorry to disturb you. (I'm sorry because I disturb you now.)

We are glad to meet you. (We are glad because I meet you here.)

   3、如果谓语动词表示的是一种意向,to do 则发生在谓语动词之后.如：

I don‘t want to see anyone. (it is no my wish that I will seeanyone.)

I have something to tell you. (I have something that I am going totell you.) expect

You can't expect me to approve of it. (You can't expect that I willapprove of it.) 你别指望我赞成.

I don’t know what to do. (I don’t know what I should do later.)

We hope you to join us. (We hope that you will join us.)

二．完成式 to have done 表示不定式发生的时间早于谓语动词.如：

I‘m sorry to have disturbed you. (=I‘m sorry that I had disturbedyou.)

he hoped to have studied English. (=he hoped that he had studiedEnglish.) 我倒是希望学过英语（虚拟语气）.

I meant to have telephoned, but later I forgot. （= I meant that I had telephoned,）

He was impatient to have finished the job. （He was impatient that he hadfinished the job）

I am sorry to have lost your key. (I am sorry that I had lost yourkey.)

I remember to have seen her. (I remember that I had seen her.)

He was reported to have died. (He was reported that he had died.)

三、进行式 to be doing 表示不定式与谓语动词的行为同时发生.如：

You had better to be leaving. (You had better that you were leavingnow.) [虚拟语气]

He seemed to be learning and his mood lightened. (It seemed that he was learning and his moodlightened.) 他好象正在入门,情绪也开朗多了.

She appeared to be watching him.  (It appeared that she was watching him.)她似乎在观察着他.
