語法：復合不定代詞或副的構成及用法
構成：由some, any, no, every分別加上-body, -thing, -one構成的不定代詞叫做合成不定代詞;加上-where構成副詞。
用法：
(1)合成不定代詞在句中可以作主語，賓語或表語等。
Nobody will listen to him. He wants something to eat.
(2)不定代詞作主語時，謂語動詞要用單數。
There is nothing wrong with the TV.
Everybody likes reading.
(3)some-不定代詞，通常用於肯定句中; any-不定代詞則多用於否定句、疑問句中。
但some-可用於表請求、邀請、預料對方會作肯定回答時的疑問句中。
Someone is calling me.
There isn’tanyone else there.
Is anybody over there?
Could you give me something to eat?
(4)形容詞修飾不定代詞時，通常要放在不定代詞之後。
There is something delicious on the table.
(5)somewhere, anywhere, nowhere, everywhere用作副詞。
Flowers come out everywhere.
註：①形容詞修飾不定代詞要後置：anything special
②不定代詞做主語時謂語用單數.

(1) 其否定式為not as/so +adj./adv. +as。

E.g. Your bag is twice as expensive as mine.
你的包比我的貴一倍。
3. You can tell that Lisa really wanted to win, though.
不過，你能看得出來，麗薩確實想贏。
win此處用作不及物動詞，意為“贏;獲勝”;win還可用作及物動詞，意為“贏得;在„„中獲勝”，此時其後的賓語為比賽的項目、獎品或戰爭等。
E.g. He won the first prize.
Who won the race?

④ 人教版八年級上冊英語語法知識梳理
1) leave的用法
1.「leave+地點」表示「離開某地」。例如：
When did you leave Shanghai? 你什麼時候離開上海的？
2.「leave for+地點」表示「動身去某地」。例如：
Next Friday, Alice is leaving for London. 下周五，愛麗斯要去倫敦了。
3.「leave+地點+for+地點」表示「離開某地去某地」。例如：
Why are you leaving Shanghai for Beijing? 你為什麼要離開上海去北京？
2) 情態動詞should「應該」學會使用
should作為情態動詞用，常常表示意外、驚奇、不能理解等，有「竟會」的意思，例如：
How should I know? 我怎麼知道？
Why should you be so late today? 你今天為什麼來得這么晚？
should有時表示應當做或發生的事，例如：
We should help each other.我們應當互相幫助。
我們在使用時要注意以下幾點：
1. 用於表示「應該」或「不應該」的概念。常指長輩教導或責備晚輩。例如：
You should be here with clean hands. 你應該把手洗干凈了再來。
2.用於提出意見勸導別人。例如：
You should go to the doctor if you feel ill. 如果感覺不舒服，你最好去看醫生。
3. 用於表示可能性。should的這一用法是考試中常常出現的考點之一。例如：
We should arrive by supper time. 我們在晚飯前就能到了。
She should be here any moment. 她隨時都可能來。
3) What...? 與 Which...?
1. what 與 which 都是疑問代詞，都可以指人或事物，但是what僅用來詢問職業。如：
What is your father? 你父親是干什麼的？
該句相當於：
What does your father do?
What is your father's job?
Which 指代的是特定范圍內的某一個人。如：
---Which is Peter? 哪個是皮特？
---The boy behind Mary. 瑪麗背後的那個男孩。
2.What...? 是泛指，所指的事物沒有范圍的限制；而 Which...? 是特指，所指的事物有范圍的限制。如：
What color do you like best?（所有顏色）你最喜愛什麼顏色？
Which color do you like best, blue, green or yellow?
你最喜愛哪一種顏色？ （有特定的范圍）
3. what 與 which 後都可以接單、復數名詞和不可數名詞。如：
Which pictures are from China?哪些圖片來自中國？
4) 頻度副詞的位置
1.常見的頻度副詞有以下這些：
always（總是，一直）
usually（通常）
often（常常，經常）
sometimes（有時候）
never（從不）
2.頻度副詞的位置：
a.放在連系動詞、助動詞或情態動詞後面。如：
David is often arrives late for school.大衛上學經常遲到。
b.放在行為動詞前。如：
We usually go to school at 7:10 every day.我們每天經常在7:10去上學。
c.有些頻度副詞可放在句首或句尾，用來表示強調。如：
Sometimes I walk home, sometime I ride a bike.
有時我步行回家，有時我騎自行車。
3.never放在句首時，主語、謂語動詞要倒裝。如：
Never have I been there.我從沒到過那兒。
5) every day 與 everyday
1. every day作狀語，譯為「每一天」。如：
We go to school at 7:10 every day.
我們每天7：10去上學。
I decide to read English every day.
我決定每天讀英語。
2. everyday 作定語，譯為「日常的」。
She watches everyday English on TV after dinner.
她晚飯後在電視上看日常英語。
What's your everyday activity?你的日常活動是什麼？
6) 什麼是助動詞
1.協助主要動詞構成謂語動詞片語的詞叫助動詞（Auxiliary Verb）。被協助的動詞稱作主要動詞（Main Verb）。助動詞自身沒有詞義，不可單獨使用。例如：
He doesn't like English.他不喜歡英語。
（doesn't是助動詞，無詞義；like是主要動詞，有詞義）
2.助動詞協助主要動詞完成以下功用，可以用來：
a. 表示時態，例如：
He is singing.他在唱歌。
He has got married.他已結婚。
b. 表示語態，例如：
He was sent to England.他被派往英國。
c. 構成疑問句，例如：
Do you like college life?你喜歡大學生活嗎？
Did you study English before you came here?你來這兒之前學過英語嗎？
d. 與否定副詞not合用，構成否定句，例如：
I don't like him. 我不喜歡他。
e. 加強語氣，例如：
Do come to the party tomorrow evening. 明天晚上一定來參加晚會。
He did know that. 他的確知道那件事。
3.最常用的助動詞有：be, have, do, shall, will, should, would
7) forget doing/to do與remember doing/to do
1.forget to do忘記要去做某事(未做)；forget doing忘記做過某事(已做)
The light in the office is still on. He forgot to turn it off.
辦公室的燈還在亮著，它忘記關了。(沒有做關燈的動作)
He forgot turning the light off.
他忘記他已經關了燈了。( 已做過關燈的動作)
Don't forget to come tomorrow.
別忘了明天來。(to come動作未做)
典型例題
---- The light in the office is still on.
---- Oh，I forgot___.
A. turning it off B. turn it off
C. to turn it off D. having turned it off
答案：C。由the light is still on 可知燈亮著，即關燈的動作沒有發生，因此用forget to do sth.而forget doing sth表示燈已經關上了，而自己忘記了這一事實。此處不符合題意。
2.remember to do記得去做某事(未做)；
remember doing記得做過某事(已做)
Remember to go to the post office after school.記著放學後去趟郵局。
Don't you remember seeing the man before? 你不記得以前見過那個人嗎?
8) It's for sb.和 It's of sb.
1.for sb. 常用於表示事物的特徵特點，表示客觀形式的形容詞，如：
easy, hard,difficult,interesting,impossible等：
It's very hard for him to study two languages. 對他來說學兩門外語是很難的。
2.of sb的句型一般用表示人物的性格，品德，表示主觀感情或態度的形容詞。如：
good, kind, nice, clever, foolish, right。
It's very nice of you to help me. 你來幫助我，你真是太好了。
3.for 與of 的辨別方法：
用介詞後面的代詞作主語，用介詞前邊的形容詞作表語，造個句子。如果道理上通順用of，不通則用for。如：
You are nice.(通順，所以應用of)。
He is hard.(人是困難的，不通，因此應用for。)
9) 對兩個句子的提問
新目標英語在命題中有將對句子劃線提問這一題型取消的趨勢，現在採取的作法是對一個句子進行自由提問。例如：
句子：The boy in blue has three pens.
提問：1. Who has three pens?
2. Which boy has three pens?
3. What does the boy in blue have?
4. How many pens does the boy in blue have?
很顯然，學生多了更多的回答角度，也體現了考試的靈活性。再如：
句子：He usually goes to the park with his friends at 8:00 on Sunday.
提問：1. Who usually goes to the park with his friends at 8:00 on Sunday?
2. Where does he usually go with his friends at 8:00 on Sunday?
3. What does he usually do with his friends at 8:00 on Sunday?
4. With whom does he usually go to the park at 8:00 on Sunday?
5. What time does he usually go to the park with his friends on Sunday?
6. When does he usually go to the park with his friends?
10) so、such與不定冠詞的使用
1.so與不定冠詞a、an連用，結構為「so+形容詞+a/an+名詞」。如：
He is so funny a boy.
Jim has so big a house.
2.such與不定冠詞a、an連用，結構為「such+a/an+形容詞+名詞」。如：
It is such a nice day.
That was such an interesting story.
11) 使用-ing分詞的幾種情況
1.在進行時態中。如：
He is watching TV in the room.
They were dancing at nine o'clock last night.
2.在there be結構中。如：
There is a boy swimming in the river.
3.在have fun/problems結構中。如：
We have fun learning English this term.
They had problems getting to the top of the mountain.
4.在介詞後面。如：
Thanks for helping me.
Are you good at playing basketball？
5.在以下結構中：
enjoy doing sth樂於做某事
finish doing sth 完成做某事

2.名詞有單數名詞和復數名詞。如：
man（單數）---men（復數） banana（單數）---bananas（復數）
3.動詞有原形，第三人稱單數形式，-ing分詞，過去式，過去分詞。如：
go---goes---going---went---gone
work---works---working---worked---worked
watch---watches---watching---watched---watched
當主語為第三人稱單數的時候，謂語動詞必須用相應的第三人稱單數形式。如：
The boy wants to be a sales assistant.
Our English teacher is from the US.
Their daughter makes her breakfast all by herself.
