初中二年级英语语法 ‎1) leave的用法 ‎  1."leave+地点"表示"离开某地"。例如:‎ ‎  When did you leave Shanghai?‎ ‎  你什么时候离开上海的? ‎ ‎  2."leave for+地点"表示"动身去某地"。例如:‎ ‎  Next Friday, Alice is leaving for London.‎ ‎  下周五,爱丽斯要去伦敦了。‎ ‎  3."leave+地点+for+地点"表示"离开某地去某地"。例如:‎ ‎  Why are you leaving Shanghai for Beijing?‎ ‎  你为什么要离开上海去北京?‎ ‎2) 情态动词should"应该"学 会 使用 ‎  should作为情态动词用,常常表示意外、惊奇、不能理解等,有"竟会"的意思,例如:‎ ‎  How should I know? 我怎么知道?‎ ‎  Why should you be so late today? 你今天为什么来得这么晚?‎ ‎  should有时表示应当做或发生的事,例如:‎ ‎  We should help each other.我们应当互相帮助。‎ ‎  我们在使用时要注意以下几点:‎ ‎  1.用于表示"应该"或"不应该"的概念。此时常指长辈教导或责备晚辈。‎ ‎  例如:‎ ‎  You should be here with clean hands. 你应该把手洗干净了再来。‎ ‎  2.用于提出意见劝导别人。例如:‎ ‎  You should go to the doctor if you feel ill.‎ ‎  如果你感觉不舒服,你最好去看医生。‎ ‎  3.用于表示可能性。should的这一用法是考试中常常出现的考点之一。例如:‎ ‎  We should arrive by supper tim e. 我们在晚饭前就能到了。‎ ‎  She should be here any moment . 她随时都可能来。‎ ‎3) What...? 与 Which...?‎ ‎  1. what 与 which 都是疑问代词,都可以指人或事物,但是what仅用来询问 ‎  职业。如:‎ ‎  What is your father? 你父亲是干什么的?‎ ‎  该句相当于:‎ ‎  What does your father do?‎ ‎  What is your father's job?‎ ‎  Which 指代的是特定范围内的某一个人。如:‎ ‎  ---Which is Peter? 哪个是皮特?‎ ‎  ---The boy behind Mary. 玛丽背后的那个男孩。‎ ‎  2. What...? 是泛指,所指的事物没有范围的限制;而 Which...? 是特指,‎ ‎  所指的事物有范围的限制。如:‎ ‎  What color do you like best?(所有颜色)你最喜爱什么颜色?‎ ‎  Which color do you like best, blue, green or yellow?‎ ‎  你最喜爱哪一种颜色? (有特定的范围)‎ ‎  3. what 与 which 后都可以接单、复数名词和不可数名词。如:‎ ‎  Which pictures are from China?  哪些图片来自中国?‎ ‎4) 频度副词的位置 ‎  1.常见的频度副词有以下这些:‎ ‎  always(总是,一直)‎ ‎  usually(通常)‎ ‎  often(常常,经常) ‎ ‎  sometimes(有时候)‎ ‎  never(从不)‎ ‎  2.频度副词的位置:‎ ‎  a.放在连系动词、助动词或情态动词后面。如:‎ ‎  David is often arrives late for school.大卫上学经常迟到。‎ ‎  b.放在行为动词前。如:‎ ‎  We usually go to school at 7:10 every day.‎ ‎  我们每天经常在7:10去上学。‎ ‎  c.有些频度副词可放在句首或句尾,用来表示强调。如:‎ ‎  Sometimes I walk home, sometime I ride a bike.‎ ‎  有时我步行回家,有时我骑自行车。‎ ‎  3.never放在句首时,主语、谓语动词要倒装。如:‎ ‎  Never have I been there.我从没到过那儿。‎ ‎5) every day 与 everyday ‎  1. every day 作状语,译为"每一天"。如:‎ ‎  We go to school at 7:10 every day.‎ ‎  我们每天7:10去上学。‎ ‎  I decide to read English every day.‎ ‎  我决定每天读英语。‎ ‎  2. everyday 作定语,译为"日常的"。‎ ‎  She watches everyday English on TV after dinner.‎ ‎  她晚饭后在电视上看日常英语。‎ ‎  What's your everyday activity?  你的日常活动是什么?‎ ‎6) 什么是助动词 ‎  1.协助主要动词构成谓语动词词组的词叫助动词(Auxiliary Verb)。被协助的 ‎  动词称作主要动词(Main Verb)。助动词自身没有词义,不可单独使用,‎ ‎  例如:He doesn't like English. 他不喜欢英语。‎ ‎  (doesn't是助动词,无词义;like是主要动词,有词义)‎ ‎  2.助动词协助主要动词完成以下功用,可以用来:‎ ‎  a. 表示时态,例如:‎ ‎  He is singing. 他在唱歌。‎ ‎  He has got married. 他已结婚。‎ ‎  b. 表示语态,例如:‎ ‎  He was sent to England. 他被派往英国。‎ ‎  c. 构成疑问句,例如:‎ ‎  Do you like college life? 你喜欢大学生活吗?‎ ‎  Did you study English before you came here?‎ ‎  你来这儿之前学过英语吗?‎ ‎  d. 与否定副词not合用,构成否定句,例如:‎ ‎  I don't like him.  我不喜欢他。‎ ‎  e. 加强语气,例如:‎ ‎  Do come to the party tomorrow evening. 明天晚上一定来参加晚会。‎ ‎  He did know that.  他的确知道那件事。‎ ‎  3.最常用的助动词有:be, have, do, shall, will, should, would ‎ 7) forget doing/to do与remember doing/to do ‎  1.forget to do忘记要去做某事(未做);forget doing忘记做过某事(已做)‎ ‎  The light in the office is still on. He forgot to turn it off.‎ ‎  办公室的灯还在亮着,它忘记关了。(没有做关灯的动作)‎ ‎  He forgot turning the light off.‎ ‎  他忘记他已经关了灯了。( 已做过关灯的动作)‎ ‎  Don't forget to come tomorrow.‎ ‎  别忘了明天来。(to come动作未做)‎ ‎  典型例题 ‎  ---- 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 可知灯亮着,即关灯的动作没有发生,‎ ‎  因此用forget to do sth.而forget doing sth 表示灯已经关上了,而 ‎  自己忘记了这一事实。此处不符合题意。‎ ‎  2.remember to do记得去做某事(未做);‎ ‎  remember doing记得做过某事(已做)‎ ‎  Remember to go to the post office after school.‎ ‎  记着放学后去趟邮局。‎ ‎  Don't you remember seeing the man before?‎ ‎  你不记得以前见过那个人吗?‎ ‎8) It's for sb.和 It's of sb.‎ ‎  1.for sb. 常用于表示事物的特征特点,表示客观形式的形容词,如:‎ ‎  easy, hard,difficult,interesting,impossible等:‎ ‎  It's very hard for him to study two languages.‎ ‎  对他来说学两门外语是很难的。‎ ‎  2.of ‎ sb的句型一般用表示人物的性格,品德,表示主观感情或态度的形容词,‎ ‎  如:good, kind, nice, clever, foolish, right。‎ ‎  It's very nice of you to help me. 你来帮助我,你真是太好了。‎ ‎  3.for 与of 的辨别方法:‎ ‎  用介词后面的代词作主语,用介词前边的形容词作表语,造个句子。如果道理上通顺用of,不通则用for。如:‎ ‎  You are nice. (通顺,所以应用of)。‎ ‎  He is hard. (人是困难的,不通,因此应用for。)‎ ‎9) 对两个句子的提问 ‎  新目标英语在命题中有将对句子划线提问这一题型取消的趋势,现在采取的作 ‎  法是对一个句子进行自由提问。例如:‎ ‎  句子:The boy in blue has three pens.‎ ‎  提问: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?‎ ‎  很显然,学生多了更多的回答角度,也体现了考试的灵活性。再如:‎ ‎  句子:He usually goes to the park with his friends at 8:00 on Sunday.‎ ‎  提问: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.
