2、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? 我怎么知道？Why should you be so late today? 你今天為什么來得這么晚？should有時表示應(yīng)當做或發(fā)生的事，例如：We should help each other.我們應(yīng)當互相幫助。我們在使用時要注意以下幾點：1. 用于表示“應(yīng)該”或“不應(yīng)該”的概念。此時常指長輩教導或責備晚輩。例如：You should be here with clean hands. 你應(yīng)該把手洗干凈了再來。 2. 用于提出意見勸導別人。例如：You should go to the docto

3、r if you feel ill. 如果你感覺不舒服，你最好去看醫(yī)生。3. 用于表示可能性。should的這一用法是考試中常常出現(xiàn)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(yè)。如： What is your father?你父親是干什么的？該句相當于： What does your father do?What is you

4、r fathers job?Which 指代的是特定范圍內(nèi)的某一個人。如：冀教版八年級上冊英語語法點滴 2 -Which is Peter?哪個是皮特？ -The boy behind Mary.瑪麗背后的那個男孩。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）你最喜愛什么顏色？ Which color do you like best, blue, green or yellow?（有特定的范圍）你最喜愛哪一種顏色？3. what 與 which 后都可以接單、復

5、數(shù)名詞和不可數(shù)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(jīng)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(tài)動詞后面。如：David is often arrives late for school. 大衛(wèi)上學經(jīng)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(jīng)常在7：10去上學。c.有些頻度副詞可放

6、在句首或句尾，用來表示強調(diào)。如：Sometimes I walk home, sometime I rides 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 everyday1. 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

7、的”。She watches everyday English on TV after dinner.她晚飯后在電視上看日常英語。Whats your everyday activity?你的日?；顒邮鞘裁?？6) 什么是助動詞1.幫助主要動詞構(gòu)成謂語動詞詞組的詞叫助動詞（Auxiliary Verb）。被協(xié)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 doesnt like English.他不喜歡英語。（doesnt是助動詞，無詞義；like是主要動詞，有詞義）2.助動詞協(xié)助主要動詞完成以下功用，可以用來： a. 表示時態(tài)，例如：He is sin

8、ging.他在唱歌。He has got married.他已結(jié)婚。 b. 表示語態(tài)，例如：He was sent to England.他被派往英國。 c. 構(gòu)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(gòu)成否定句，例如：I dont 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

9、 that. 他的確知道那件事。3.最常用的助動詞有：be, have, do, shall, will, should, would7) forget doing/to do與remember doing/to do1.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(guān)了。(沒有做關(guān)燈的動作)He forgot turning the light off. 他忘記他已經(jīng)關(guān) ( 已做過關(guān)燈的動作)Do

10、nt 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冀教版八年級上冊英語語法點滴 3 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(guān)燈的動作沒有發(fā)生，因此用forget to do sth.而forget doing sth表示燈已經(jīng)關(guān)上了，而自己忘記了這一事實。

11、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. 記著放學后去趟郵局。Dont you remember seeing the man before? 你不記得以前見過那個人嗎?8) Its for sb.和 Its of sb.1.for sb. 常用于表示事物的特征特點，表示客觀形式的形容詞，如easy, hard, difficult, interesting, impossible等： Its very hard fo

13、個句子的提問冀教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(xiàn)在采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(xiàn)了考試的靈活性。再如：句子：He usually goes to the park with his friends at 8:0

14、0 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 t
