语法秘籍：
1. 概念 : 频度副词是用来表示动作发生频率的词，常用来表示不确定时间，主要包括always, usually, often, sometimes, hardly ever, seldom, never等。
always 意为“总是，永远”，表示频度最高。
usually 意为“通常”，即很少有例外，多用于一般现在时。
often 意为“经常”，在频度上不如usually那么频繁。
sometimes 意为“有时，偶尔”。
hardly ever 意为“几乎不，很少 ”，表示否定意义。
never 意为“从来没有，绝不”，表示否定意义。
以上几个频度副词所表示的频度，从低到高为：
never
0%
hardly ever
5%
sometimes
30%
often
60%
usually
80%
always
100%

Grammar
1、They often help with housework. 他们经常帮忙做家务。（P11）
help with意为“在某方面帮助”，是固定短语，也可写作help sb. with sth. 表示“在某方面帮助某人”
拓展：help相关短语
help sb. (to) do sth. 帮助某人做某事
help oneself to sth. 自用(食物等)
help sb. out 帮助某人克服困难
help sb. into/out of 搀扶某人进人/走出
can’t help doing sth. 禁不住做某事
with the help of 在....的帮助下
Tom often helps me learn English.
=Tom often helps me with my English.
Grammar
2、She sometimes goes shopping她有时去购物。（P11）
sometimes意为“有时”，表示动作偶尔发生，间隔较长，放于句首、句中、句末都可。
考点拓展
含“some + time”的词汇 Sometimes有时 相当于at times，表示频率
Sometime在某个时候 表示将来或过去某个不确定的时间
some times几次，几倍 表示次数或倍数
some time一段时间 表示“一段时间”
We often go there by bus, but sometimes on foot.
We shall have a school meeting sometime next week.
I met him some times in the street last month.
注意 对sometimes提问用how often，对sometime提问用when，对some times提问用how many times，对some time 提问用how long。
Grammar
3、He hardly ever watches TV.他几乎不看电视。（P11）
hardly ever相当于hardly, ever起强调作用。其中hardly用作副词，意为“几乎不/没有”，它本身具有否定意义，不能再与其他否定词连用。
【易混辨析】 hardly与hard
用法 例句
hardly 副词， 意为“几乎不” He hardly works. 他几乎不工作。
hard 用作副词，意为＂努力地＂；用作形容词，意为“硬的；困难的”。 He works hard. 他工作努力。There were some hard questions on the exam paper. 试卷中有些难题。
She hardly ever eats anything. 她几乎什么都没吃。There’s hardly any food left. 几乎没有剩下食物。
