【笔记详解】Unit 2 How often do you exercise 【人教新目标八上英语】
本单元的话题：谈论生活习惯，复习一般现在时。
本单元的语法：1.复习一般现在时；2.学习表示频度副词的用法。
频度副词
主要用法：
表示事情发生的大概频率，可用来回答how often引导的问句。
等级排序：
always(总是) > usually (通常) > often(经常) > sometimes(有时) > hardly ever(很少) > never(从不)
句中位置：
“行”前“助(系)”后，即：一般放在助动词、be动词或情态动词之后，行为（实义）动词之前。也就是说，频度副词在英语中的运用同汉语语序一致。
Peter is always late for school. Peter上学总是迟到。
I usually do my homework in the evening. 我通常在晚上做作业。
特殊疑问词：
always, sometimes, twice a day 等频度副词，用 How often
I watch TV every day.我每天都看电视
→How often do you watch TV (你多长时间看一次电视？)
注意：除了频度副词用来表示事件发生的大致频率外，“once / twice / three times a + 时间段”也可以用来表达事件发生更为精准的频率，特殊疑问词也用how often。
She eats strawberries three times a week.(对划线部分提问) →How often does she eat strawberries
She eats strawberries three times a week.(对划线部分提问)→How many times does she eat strawberries a week
