人教版八年级上册Unit 2 How often do you exercise？ 语法知识突破
人教版八年级上册Unit 2 How often do you exercise？语法知识突破人教版英语八年级上册第二单元Unit 2 How often do you exercise 语法知识突破在英语学习中，语法学习，既是一个重点，也是一个难点，每个单元的设计都是围绕一定话题，突破语法和句子知识展开的。
接下来，我们来呈现一下人教版英语八年级上册第二单元的语法如何突破？从标题看语法本单元的标题是：How often do you exercise 从标题可以看出，本单元主要谈论“频率”问题，所以，话题就是“关于日常活动的频率”，既然是询问频率，就牵涉到关于如何询问频率？如何表达频率？等一系列的问题。
语法突破：如何询问频率？英语里面，当我们要询问对方“多久做一次某事”的时候，要用“how often”来询问频率，表示“多久一次”，例如：How often do you exercise 你多久锻炼一次？How often do they go out for a picnic 他们多久出去野炊一次？从Grammar focus看语法。
语法部分从基本句型”What do you usually do “引入，通过回答，给我们展示了频率副词always , often, sometimes等的用法。
接下来，用How often do you go to the movies 再次引出频率副词的用法以及如何表示“次数”。
让我们先看语法中的句子。
What do you usually do on weekends I always exercise.What do they do on weekends They often help with housework.What does she do on weekends She sometimes goes shopping.How often do you go to the movies I go to the movies maybe once a month.How often does he watch TV He hardly ever watches TV.Do you go shopping No , I never go shopping.当询问某人周末通常做什么的时候，用到频率副词usually，它的位置“be动词的后面，行为动词的前面”。
