It a sunny morning, very cold. 这是个晴朗的早晨,但是却很冷。 however, but Part2语法点讲解 频度副词： 概念：频度副词表示动作发生的频率,通常用于一般现在时。 具体用法： ①表示具体频度 表示具体的频率、次数时,一次(once)、两次(twice)都用特定的单词来表示,三次以上用“基数词＋times”表示。 eg：I wash my hair three times a week.我一星期洗三次头发。 ②不表示具体频度 英语中还有一些频度副词不表示具体的频率、次数,但有特殊意义,如always(总是), usually(通常), often(经常), sometimes(有时), seldom(很少), hardly ever(几乎不), never(从来不)等。 这类频度副词在频率上的差异可用下图表示： 频度副词的位置 频度副词一般位于be动词、助动词或情态动词之后,实义动词之前。其中sometimes位置比较灵活,可位于句首、句中或句末。 eg：Sometimes he goes to the movies on Friday evening.他有时周五晚上去看电影。 【注意】对频度副词提问用how often。 一、根据句意,选择方框中的单词或短语填空。 always,hardly ever,never,usually,sometimes 1.
