What.是泛指,所指的事物没有范畴的限制； 而 Which.是特指,所指的事物有范畴的限制；如：What color do you like best.（全部颜色） 你最宠爱什么颜色？Which color do you like best, blue, green or yellow.（有特定的范畴）你最宠爱哪一种颜色？3. what 与 which后都可以接单、复数名词和不行数名词；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,始终） usually（通常）often （常常,常常） 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.大卫上学常常迟到；b. 放在行为动词前；如：We usually go to school at 7:10 every day.我们每天常常在 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 rides 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.5) every day 与 everyday1. 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.我打算每天读英语；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. 帮助主要动词构成谓语动词词组的词叫助动词（Auxiliary Verb）；被帮助的动词称作主要动词（Main Verb ）；助动词自身没有词义,不行单独使用,例如：He doesn't like English.他不宠爱英语；（doesn't 是助动词,无词义； like 是主要动词,有词义）2. 助动词帮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.你宠爱高校生活吗？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.我不宠爱他；e. 加强语气,例如：Do come to the party tomorrow evening. 明天晚上肯定来参与晚会；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, would7) forget doing/to do 与 remember doing/to do 1.forget to do遗忘要去做某事；未做 forget doing遗忘做过某事；已做The light in the office is still on.

How many pens does the boy in blue have.很明显,同学多了更多的回答角度, 也表达了考试的敏捷性；再如：句子： He usually goes to the park with his friends at 8:00 onSunday.提问： 1.Who usually goes to the park with his friends at 8:00on Sunday.2. Where does he usually go with his friends at 8:00 onSunday.3. What does he usually do with his friends at 8:00 onSunday.4. With whom does he usually go to the park at 8:00 onSunday.5.
