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。
