新概念英语第一册知识点:完成时
在完成时构成:主语+助动词have, has+过去分词
用法:
1) 表示过去发生的和现在有某种联系的动作,常和just, usually, already, since等时间副词连用
I have just had lunch. (饱了,不用再吃了)
He has had a cup of tea.(不渴了,不用再喝)
They have already had their holiday. (不能再度假了)
The boy has already read the book. (已经知道书的内容了,不用再看了)
2) 询问别人是否做过某事一般用现在完成时:
Have you finished your homework?
Have you been to Beijing?
Have he seen the film?
3) 表示开始于过去并持续到现在的动作
I have lived in Beijing for twenty years.
I have worked for this school for 1 year.
4) 表示一种经历,经验:去过…地方,做过…事情,经历过…事情
I have never had a bath.
I have never seen a film.
I have never been to cinema.
I have ever been to Paris.
Have been to表示去过,have gone to 表示去了

He has gone to London.(人还在那里)
5) 表示一种结果, 一般不和时间副词联用
I have lost my pen.
I have hurt myself.
He has become a teacher.
She has broken my heart.
句型变化:
★变疑问句将助动词移到句首,变否定句在助动词后面加not.
e.g. Have you lost your pen? I have not lost my pen.
★肯定回答及否定回答
Yes, I have. No, I have not.
★特殊疑问句:
What have you done?
What has he done?
一般过去时与现在完成时的区别:
凡是有明确的表示过去的时间状语的句子为过去时
注意:有些动词表示的动作有一个终点,不能再延续,因此不能和表示一段时间状语连用
错:I’ve left Beijing for 3 days.
对:I left Beijing 3 days ago. I have been away from being for 3 days.

新概念英语第一册知识点:倒装句
完全倒装:又称"全部倒装",是指将句子中的谓语全部置于主语之前。此结构通常只用于一般现在时和一般过去时。也就是谓语+主语+……
理论的东西说多了大家迷糊,其实我们通常见到的There be句型就是完全倒装句
①There be(的各种形式)+主语(+地点或时间状语)
例子:
There was problem between us.我们俩之间曾经有矛盾
There are ducks swimming in the river.河里有很多鸭子在游
②副词小品词+谓语动词+名词主语+……
例子:
Out runs a lady.跑出来一位女士
Away flew the birds.鸟儿飞走了
③过去分词或现在分词+be的各种形式+主语+……
例子:
Standing beside the table was his wife.站在桌子旁的是他的夫人
需要注意的是,某些副词开头的句子构成的完全倒装here、there、now、then、thus等副词开头的句子可构成完全倒装。条件是谓语动词是不及物动词,如arise、be、come、exist、go、follow等。需要注意的是,当主语是代词时,不能构成倒装。(方位词在句首,主语是名词,全部倒装)
例子:
Here comes Harry Potte.哈利波特来了。
Here it is.在这里。
Here is your bag.这是你的包,根据语境还可翻译为给你包。
部分倒装(PartialInversion)(又称半倒装句):指将谓语的一部分如助动词或情态动词倒装至主语之前,而谓语动词无变化。如果句中的谓语没有助动词或情态动词,则需添加助动词do,does或did,并将其置于主语之前。
表示强调倒装句最突出、最常见的修辞效果就是强调,其表现形式如下:
1.only+状语或状语从句置于句首,被该状语修饰的句子用部分倒装。
例子:
Only in this way can you solve this problem.
只有用这种方法,你才可以解决这个问题。
Only after he had spoken out the word did he realize he had made a big mistake.
只有当他已经说出那个字后才意识到自己犯了个大错误。
2.hardly,in no way,little,scarcely,seldom, never,no more,no longer,not,not only,no sooner,not only…(but also),not until…等具有否定意义的词或词组位于句首,句子用部分倒装。
例子:
No sooner had I got home than it began to rain.
我刚到家就下起了雨。
Seldom do I go to work by bus.
我很少乘公共汽车上班。
Not until twelve o'clock did she go to bed last night.
她昨晚十二点才上床睡觉。
3.so/such...that结构中的so或such位于句首可以构成部分倒装句,表示强调so/such和that之间的部分。
例子:
So unreasonable was his price that everybody startled.
他的要价太离谱,令每个人都瞠目结舌。
To such length did she go in rehearsal that the two actors walked out.
她的彩排进行得那么长,以致于那两个演员都走出去了。
以上各例都用倒装语序突出了句首成分,其语气较自然语序强烈,因而具有极佳的修辞效果。
