新概念英語第一冊知識點：完成時
在完成時構成：主語+助動詞have, has+過去分詞
用法：
1) 表示過去發(fā)生的和現(xiàn)在有某種聯(lián)系的動作，常和just, usually, already, since等時間副詞連用
I have just had lunch. (飽了，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. (已經(jīng)知道書的內容了，不用再看了)
2) 詢問別人是否做過某事一般用現(xiàn)在完成時：
Have you finished your homework?
Have you been to Beijing?
Have he seen the film?
3) 表示開始于過去并持續(xù)到現(xiàn)在的動作
I have lived in Beijing for twenty years.
I have worked for this school for 1 year.
4) 表示一種經(jīng)歷，經(jīng)驗：去過…地方，做過…事情，經(jīng)歷過…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表示去過，have gone to 表示去了
I have been to London.(人已經(jīng)回來)
He has gone to London.(人還在那里)
5) 表示一種結果， 一般不和時間副詞聯(lián)用
I have lost my pen.
I have hurt myself.
He has become a teacher.
She has broken my heart.
句型變化：
★變疑問句將助動詞移到句首，變否定句在助動詞后面加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.
★特殊疑問句：
What have you done?
What has he done?
一般過去時與現(xiàn)在完成時的區(qū)別：
凡是有明確的表示過去的時間狀語的句子為過去時
注意：有些動詞表示的動作有一個終點，不能再延續(xù)，因此不能和表示一段時間狀語連用
錯：I’ve left Beijing for 3 days.
對：I left Beijing 3 days ago. I have been away from being for 3 days.

新概念英語第一冊知識點：倒裝句
完全倒裝：又稱"全部倒裝",是指將句子中的謂語全部置于主語之前。此結構通常只用于一般現(xiàn)在時和一般過去時。也就是謂語+主語+……
理論的東西說多了大家迷糊，其實我們通常見到的There be句型就是完全倒裝句
?、賂here be(的各種形式)+主語(+地點或時間狀語)
例子：
There was problem between us.我們倆之間曾經(jīng)有矛盾
There are ducks swimming in the river.河里有很多鴨子在游
?、诟痹~小品詞+謂語動詞+名詞主語+……
例子：
Out runs a lady.跑出來一位女士
Away flew the birds.鳥兒飛走了
?、圻^去分詞或現(xiàn)在分詞+be的各種形式+主語+……
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，某些副詞開頭的句子構成的完全倒裝here、there、now、then、thus等副詞開頭的句子可構成完全倒裝。條件是謂語動詞是不及物動詞，如arise、be、come、exist、go、follow等。需要注意的是，當主語是代詞時，不能構成倒裝。(方位詞在句首，主語是名詞，全部倒裝)
例子：
Here comes Harry Potte.哈利波特來了。
Here it is.在這里。
Here is your bag.這是你的包，根據(jù)語境還可翻譯為給你包。
部分倒裝(PartialInversion)(又稱半倒裝句)：指將謂語的一部分如助動詞或情態(tài)動詞倒裝至主語之前,而謂語動詞無變化。如果句中的謂語沒有助動詞或情態(tài)動詞，則需添加助動詞do,does或did，并將其置于主語之前。
表示強調倒裝句最突出、最常見的修辭效果就是強調，其表現(xiàn)形式如下：
1.only+狀語或狀語從句置于句首，被該狀語修飾的句子用部分倒裝。
例子：
Only in this way can you solve this problem.
只有用這種方法，你才可以解決這個問題。
Only after he had spoken out the word did he realize he had made a big mistake.
只有當他已經(jīng)說出那個字后才意識到自己犯了個大錯誤。
2.hardly,in no way,little,scarcely,seldom, never,no more,no longer,not,not only,no sooner,not only…(but also),not until…等具有否定意義的詞或詞組位于句首，句子用部分倒裝。
例子：
No sooner had I got home than it began to rain.
我剛到家就下起了雨。
Seldom do I go to work by bus.
我很少乘公共汽車上班。
Not until twelve o'clock did she go to bed last night.
她昨晚十二點才上床睡覺。
3.so/such...that結構中的so或such位于句首可以構成部分倒裝句,表示強調so/such和that之間的部分。
例子：
So unreasonable was his price that everybody startled.
他的要價太離譜，令每個人都瞠目結舌。
To such length did she go in rehearsal that the two actors walked out.
她的彩排進行得那么長，以致于那兩個演員都走出去了。
以上各例都用倒裝語序突出了句首成分，其語氣較自然語序強烈，因而具有極佳的修辭效果。
