2、情態(tài)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有時表示應當做或發(fā)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. 用于表示“應該”或“不應該”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 d

3、octor 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 your f

4、ather'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、復數名詞和不可數名詞。如： whi

5、ch 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(tài)動詞后面。如：david is often late for school.大衛(wèi)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：sometime

6、s i walk home, sometime i ride a bike.有時我步行回家，有時我騎自行車。放在句首時，主語、謂語動詞要倒裝。如：never have i been there. 我從未去過那里。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“日常的，每天的”。she watches everyday englis

7、h on tv after dinner.她晚飯后在電視上看日常英語。what's your everyday activity?你的日?；顒邮鞘裁矗?) 什么是助動詞1.協助主要動詞構成謂語動詞詞組的詞叫助動詞（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(tài)，例如：he is singing.他在唱歌。he ha

8、s got married.他已結婚。 b. 表示語態(tài)，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

9、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 sth忘記要去做某事。(未做) forget doing sth 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)d

10、on'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 off2. 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。don&

11、#39;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：it's very hard for him to study two languages. 對他來說學兩門外語是很難的。 sb的句型一般用表示人物的性格，品德，表示主觀感情或態(tài)度的形容詞，如good, kind, nice, clever,

12、foolish, right。 it's very nice of you to help me. 你來幫助我，你真是太好了。 與of 的辨別方法：用介詞后面的代詞作主語，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： has three pens

13、? boy has three pens? does the boy in blue have? 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： usually goes to the park with his friends at 8:00 on sunday? does he usually go with his friends at 8:00 on sunday?

14、 does he usually do with his friends at 8:00 on sunday? whom does he usually go to the park at 8:00 on sunday? time does he usually go to the park with his friends on sunday? does he usually go to the park with his friends?10) so、such與不定冠詞的使用與不定冠詞a、an連用，結構為“so+形容詞+a/an+名詞”。如：he is so funny a boy.jim

15、 has so big a house.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(tài)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：

16、we have fun learning english this term.they had problems getting to the top of the mountain.4.在介詞后面。如：thanks for helping me.are you good at playing basketball.5.在以下結構中：enjoy doing sth樂于做某事finish doing sth完成做某事feel like doing sth 想要做某事stop doing sth 停止做某事forget doing sth 忘記做過某事go on doing sth 繼續(xù)做某事remember doing sth 記得做過某事like doing sth 喜歡做某事keep sb doing sth
