人教版英语八年级上册 Unit 2 How often do you exercise? 新课预习练习（含答案）

Unit 2 How often do you exercise
第一部分
知识点讲解
重点句型
1.-What do you usually do on weekends -I often go to the movies.
（1） on weekends/on the weekend 在周末
（2） go to the movies 去看电影
（3）第一个do是助动词，第二个do是实义动词
2．hardly ever 几乎从不 hardly ever 相当于 hardly，ever起强调作用。
hardly 为副词,意为“几乎不,几乎没有”,相当于almost not，本身具有否定含义，不能再使用其他否定词。如：
She hardly eats anything.
辨析：hardly和hard
①hard作形容词，意为“困难的，艰苦的，硬的”。
②hard作副词，意为“努力地，猛烈地”。
③hardly意为“几乎不”。
3.-How often do you watch TV -Twice a week.
（1）how often 意为“多久一次，多长时间一次”，用来提问频率。
（2）twice a week一周两次
拓展：一次 once两次 twice
三次或三次以上：基数词＋times 如 three times four times
4. What's your favorite program = What program do you like best 你最喜欢的节目是什么？
5．How come？怎么回事？怎么会？表示某件事情很奇怪，有点想不通；可单独使用，也可引导一个问句。相当于疑问词why。但 how come 开头的特殊疑问句使用的仍是陈述语序。
How come you didn't tell me about it = Why you didn't tell me about it

语法知识：频度副词
1．频度副词的含义
常用的频度副词按高低依次为
（1）表示次数、频率的副词称为频度副词。always>usually>sometimes>seldom>hardly ever>never
（2）表示具体的频率、次数时，一次用once，两次用twice，三次或三次以上用“基数词＋times”表示：three times，four times，six times。
2．频度副词在句中的位置
（1）频度副词一般在实义动词之前，be动词、助动词或情态动词之后。
如：We never eat junk food. Lucy is sometimes very busy.
（2）有些频度副词也可位于句首，但表示不同含义。
①sometimes 常位于句首，和位于句中区别不大。如：
Sometimes Jack plays computer games.
②often用于句首时，通常表示强调，且其前一般有quité，very修饰。如：
Very often he goes online.
③usually也可位于句首，其前不用修饰语。如：
Usually, my father goes up early.
①always一般不用于句首，但可以用在祈使句中。如：
Always remember this.
对频度副词提问时,用how often。如：
-How often do you go to the movies -Once a month.
