三点剖析

一、考点:

频度副词是表示某事发生频率的副词,即用来表示某事在一段时间内所发生的次数。

always,often,usually,sometimes,hardly,never是英语中最常见的几个频度副词,他们一般放在行为动词之前,be动词、助动词及情态动词之后。

但它们的含义及表示的频率是不同的。

此外。

还有一些表示频率的词组,如onceaweek,twiceamonth,threetimesayear,fourtimesayear等,它们准确地表达出事情发生的频率。

Idrinkmilkandeatvegetableseveryday.我每天喝牛奶,吃蔬菜。

Iexerciseonceaweek.我每周锻炼一次。

Ivisitmygrandmotherfourtimesayear.我一年看望我奶奶四次。

 

二、易错点:

sometimes.sometime,sometime,sometimes

sometimes

意为“有时”,多用于一般现在时,对它进行提问常用howoften

sometime

副词,同sometime,意为“在某时(过去或将来)”表示的是不确切或尚未

确定的时间,对它提问用when。

sometimes

名词短语,意为“几次/倍”。

time是可数名词,对它提问用howmanytimes
