英语时态的问题

A gentleman wants to see you是一般现在时,主语是第三人称单数的形式,后面的谓语动词要用单三的形式。 请问还有没有这方面要记的。
例如,什么什么时,第几人称什么形式动词要用什么形式这类要背的?

还有个问题就是,在时态方面,主句用什么时态,从句就要用什么时态,这方面有没有要死记硬背的。

在英语中,不同时间发生的动作和情况,要用不同的动词形式表示。这种不同的动词形式叫做动词的时态。我们初级阶段接触到的动词的时态主要有: 一般现在时态, 一般过去时态, 一般将来时态,现在进行时态,过去进行时态,现在完成时态,过去完成时态。判断一个句子使用什么时态主要看这个句子中的动词,其次看句子中的副词和时间状语。在这讲中我们先来学习一般现在时态。

一般现在时态
一般现在时的用法:
表示经常或者反复发生的动作。如: 我每天吃午饭。I have lunch every day.
还表示现在存在的一种状态.。如:我姐姐是一位老师。My sister is a teacher.

一般现在时态经常与 often(经常)sometimes(有时)always(总是)usually(通常)等副词连用,也经常与 every day(每天), every week(每周), every month(每月), every term(每学期), every year(每年), once a week (一周一次),twice a year(一年两次)等时间状语连用。

1.一般现在时态分为 be 动词的一般现在时和实义动词的一般现在时。
1) be 动词包括 am,is,are,中文为“是”,这三个词的用法要随着主语的变化而变化。“am” 用于第一人称单数(I);“is”用于第三人称单数(he,she,it);“are”用于第一人称复数(we),第二人称单数和复数(you), 第三人称复数( they)。 可以记住以下顺口溜: am 是专门来管“我”,is 只管“他,她,它”,are 就管“你”和“大家”。

2)一般疑问句和否定句
I am a teacher. (我是一位老师)
You are his friend.(你是他的朋友)
She is a nurse.(她是一名护士)
以上三个句子都是肯定句。此类句子变成疑问句和否定句时,有些地方的语序和汉语不同,需特别注意。变为疑问句时,把动词 be“am,is,are”放在句首,回答时也要使用 be 动词;变为否定句时,把表示否定的not 放在“am is are”的后面,其中可以简写为:
is not ---- isn't
are not ---- aren't
am not 没有简写形式。
如:Are you a teacher? Yes, I am. (No, I am not.)
Are you his friend? Yes, you are. (No, you are not.)
Is she a nurse? Yes, she is. (No, she is not.)

注意:如果 are not, is not 放在句尾时,不能使用简写,必须写出整个单词。

否定句为:I am not a teacher./ You are not his friend. /She is not a nurse.

3)如果句子的动词不是 be 动词“am is are”而是其他实义动词, 疑问句和否定句要借助于助动词“do”或者“does”, 也就是说 be 动词和实义动词原形不能同时使用。 这里的“do”“does”本身没有什么意义,只是帮助构成疑问句和否定句。一般疑问句读时必须用降调。
“do”和“does”的使用要随着人称的变化而变化。请看下面两组句子,注意区分他们的共同点和不同点。
I go to school every day. He goes to school every day.
I don't go to school every day. He doesn't go to school every day.
Do you go to school every day? Does he go to school every day?
Yes, I do. (No, I don't) Yes, he does. (No, he doesn't)

这两组句子中,由于人称的不同,句子的结构也不同,具体如下:
当主语是第三人称单数时,肯定句为:主语 + 动词的 s 形式 + 宾语
否定句为:主语 + 助动词 doesn't + 动词原形 + 宾语
疑问句为:Does + 主语 + 动词原形 + 宾语
肯定回答和否定回答也要使用助动词 does.
注:第三人称单数用了 does 后面就不用动词的 s 形式了,而用动词原形。

动词的一般现在时态, 除了第三人称单数(he she it) 外,其余都用动词原形。当主语是其他人称时,肯定句为:主语+动词原形 + 宾语
否定句为:主语 + 助动词 don't + 动词原形 + 宾语
疑问句为:Do + 主语 + 动词原形 + 宾语
肯定回答和否定回答也要使用助动词 do。
注:变为疑问句,要在句首加“do”; 变为否定句, 要在动词前面加“do not”, 可以简写为“don't”.

请说出下列句子:(注意 be 动词和实义动词的用法)
你是一位学生吗? 我经常去公园。 我们每天看电视。 小明每天都读书。
你妈妈经常打球吗? 是的,她经常打球。

英语中六大从句用法总结
1.主语从句
1)主语从句可直接位于主语的位置,如果从句较长,谓语又较短,可用it作形式主语,而将从句放在句末。常见的句型有:
*It is a fact\a pity\a question\good news that...
*It seems\appears\happened\has turned out that...
*It is clear\important\likely\possible that...
*It is said\reported\estimated\has been proved that...
It is said that comic books create a connection between people of the same generation.
It seems that the performance is very useful.

2)what引导的主语从句表示“...的东西时”,一般不用it作形式主语。
What we lack is experience.

3)what,who,when,why,whether等词含有各自的疑问意义,但它们引导的主语从句,都用陈述语序。
How the plan is to be carried out should be discussed again.
I did know why I felt like crying.

2.宾语从句
1)宾语从句可位于及物动词、介词和某些形容词后。连词that常可省略。介词后一般接疑问词引导的宾语从句。in that(因为),except that(除了),but that(只是)已构成固定搭配,其他介词后一般不接that引导的宾语从句。
*I promised that I would change the situation.
*All this is different from what American young people would say about friendship.
*He is certain that watching so much television is not good for children.
*This article is well-written except that it is a bit too long.

2)宾语从句后如有宾补,要用形式宾语it来代替,而把宾语从句移至宾补之后。
He has made it clear that he would not change his mind.

3)在think,believe,suppose,expect等动词后的宾语从句中,如果谓语是否定的,一般将否定词移至主句谓语上,宾语从句则变成肯定形式。
He didn't think that the money was well spent.

3.表语从句
表语从句出现在结构为“主语+系动词+表语从句”的句子中。表语从句除可用that,what,when,why,whether,how等引导外,还可由because,as if(though)等引导。that常可省略。如主句主语为reason,只能用that引导表语从句,不可用because.
Perhaps the most important thing to remember is that there is no one common type of life in America.

The reason why so many people died there is that there were not enough food supplies.

It looks as if successful international cultural communication will make the world smaller.

4.同位语从句
同位语从句用于对前面出现的名词作进一步说明,一般用连词that引导,由于先行名词的意义不同,也可用whether,who,when,where,what,why,how等引导。常见的先行名词有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有时由于谓语较短,将同位语从句位于谓语之后。

She finally made the decision that she would join the fashion show.

I had no idea how many books I could borrow at a time.

The news came that their team had won the championship.

5.定语从句
定语从句所修饰的先行词可以是名词或代词,也可以是一个句子。定语从句通常位于先行词之后,由关系代词或关系副词引导。

*限制性定语从句
限制性定语从句修饰先行词,对先行词起修饰作用,紧接先行词之后,无逗号,若省去,原句意思不完整。引导定语从句的关系代词有who,whom,whose,which,that等。who,whom,whose用于指人,whose有时也可指物,相当于of which;which用于指物;that既可指人也可指物,但只用于限制性定语从句中。关系代词除了引导定语从句,替代先行词外,还在从句中担任主语、宾语、定语等。
The computers and cables which make up the Internet are owned by people and organizations.

Those who live alone or who are sick may have trouble in getting close to other people.

The girl whose parents died in an accident is living with her grandmother.

1)当先行词是all,anything,everything,something,nothing等不定代词或先行词前有first,last,any,few,much,some,no,only以及形容词最高级修饰时,只能用关系代词that引导从句。
That is all that I've heard from him.

He's the first person that I'm going to interview this afternoon.

2)关系代词的省略
在从句中作宾语的关系代词常可省略。关系代词紧跟介词,作介词宾语时不可用that,只可用which或whom引导从句,并且不可省略,但当介词位于宾语从句句末时,作为介词宾语的关系代词仍可用that,也可省略。
This is one of those things with which we have to put up.

This is one of those things (which\that) we have to put up with.

3)引导定语从句的关系副词有when,where,why等。关系副词在从句中作状语,意义上相当于一个“介词+which”的结构。
Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings.

No one knows the reason why(=for which) he was so angry that day.

5.定语从句
*非限制性定语从句
非限制性定语从句既可修饰先行词,也可修饰整个主句,起补充说明作用,与主句之间有逗号隔开,若省去,原句意思不受影响。不可用that引导非限制性定语从句。关系词不可省略。

Every object has a gravitational pull,which is rather like magnetism.

*“介词+which\whom\whose”引导的定语从句
“介词+which\whom\whose”可引导限制性定语从句,也可引导非限制性定语从句,该结构中介词的选择取决于从句谓语动词的固定搭配,或先行词的习惯搭配。

This is the computer on which he spent all his savings

It is written by a person with whom we are all familiar.

*as引导的定语从句
as引导的定语从句主要用于“such...as”及“the same...as”的结构中,代替先行词是人或物的名词。as引导非限制性定语从句时,代替整个主句,从句可位于主句之前、之后或中间。

These are not such problems as can be easily solved.(as代替先行词problems)

As is mentioned above,no single company or group can control what happens on the Internet.(as代替主语)

6.状语从句

*时间状语从句
引导时间状语从句的从属连词和词组有:
1)when,whenever,while,as,after,before,since,till,until,once等。
We have learnt quite a lot about it since we came here.
2)as soon as,hardly(scarcely)...when,no sooner...than,each(every) time,the moment,immediately(that)等。
As soon as I sent an e-mail message,I received positive responses.
The moment he heard the good news,he jumped with joy.

*地点状语从句
引导地点状语从句的连词是where,wherever.
Wherever she went,she took her little daughter with her.

*原因、结果和目的状语从句
1)引导原因状语从句的从属连词有:because,as,since,now(that),seeing that,considering that,in that等。
Considering that he is a freshman,we must say he is doing well.
2)引导结果状语从句的连词有:so...that,such...that
,so that,that,so等。

3)引导目的状语从句的连词有:so that,in order that,for fear that,lest等,从句常使用may,might,can,could,would等情态动词。
We got up early this morning so that we could catch the first bus to the railway station.

*条件和让步状语从句
1)引导条件状语从句的连词和词组有if,unless,as(so) long as,on condition that,in case,provided(providing) that,supposing等。
As long as you have the right equipment,you can use a telephone line to transmit computer data.
2)引导让步状语从句的连词和词组有though,although,whether,even though,even if,no matter what(when,how...),whatever(whenever,wherever,however....)等。though,even if等引导状语从句可转换成含有as的部分倒装结构,具有强调意义。其结构为“形容词(副词、动词、名词)+as+主语+谓语”。
No matter what you may say,I would not change my mind.
Young as he is,he is quite experienced in this work.(=though he is young)
Child as he is,he can speak English fluently.(=though he is a child)

*方式状语从句
引导方式状语从句的连词有as,just as,as if,as though等。as if,as though引导的状语从句中,谓语动词常用虚拟语气,表示与事实相反。
The young man made the experiment just as the teacher had taught him.
Everything went on as usual as if nothing had happened.
