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”。

Unit 2 How often do you exercise一、必背短语。

【教材内容解析】Section A1.What do you usually do on weekends (P. 9)2.on weekends意为“在周末”，泛指每个周末，on the weekend则表示“在这个周末”，特指某个周末；在英式英语中，在周末也可以用at the weekend或者at weekends。

I like going fishing on weekends.He wants to do something special on the weekend.3.help with homework (P. 9)help表示“帮助”时，常用的句型为：help sb. with sth. 帮助某人某事；help sb. (to) do sth. 帮助某人做某事。

Can you help me with my homework?He often helps his mother clean do housework.4.sometimes (P. 9)sometimes是频度副词，意为“有时”，相当于at times。

I sometimes play computer games on weekends.【拓展】辨析sometimes, some times, sometime与some time5.hardly ever (P. 9)hardly作副词，表示“几乎不”；hard用作副词表示“努力地、猛烈地”，作形容词表示“硬的、困难的”。

He hardly works.He works hard.This is a hard work.6.How often do you watch TV?(P. 9)how often意为“多久一次”用来提问频率，常用表示频率的副词或者短语来回答，如twice a week, sometimes, every day, always等。
