【词汇用法】
hardly ever
意为“几乎不曾，很少”，常置于句中。
她很少游泳。She hardly ever swims.
她几乎从不给我打电话。She hardly ever calls me.
hardly与hard 的意义及用法辨析
hardly副词，“几乎不，几乎没有”，表示否定意义，同义短语为almost not。含有hardly的句子是否定句。可修饰动词或与ever连用构成词组。
例：我几乎什么都看不见。 I can hardly see.
hard 作副词，“努力地，猛烈地”，修饰动词；作形容词，“困难的，硬的”，修饰名词。
例：雨下得很大。 It is raining hard. （作副词）
石头很硬。The stone is very hard. （作形容词）
【重点语法】
常见频度副词按频率大小排列如下：
always（100%）>usually（80%）>often（60%）>sometimes（40%）>seldom（20%）>hardly (10%)>rarely never（1%）
用法位置
◆频度副词在句中习惯上位于be动词、助动词等之后，行为动词之前。
1. 在be动词之后。如：
She is sometimes very busy. 她有时很忙。
2. 在第一个助动词或情态动词之后。如：
I will never forget this lesson. 我将永远忘不了这一课。
3. 在实义动词之前。如：
◆如果有两个助动词，频度副词通常放在第一个助动词后面。如：
We have never been invited to one of their parties. 他们聚会，一次也没邀请过我们。
◆always 频率最高，表示动作重复、状态继续，表示“一直、总是”，其反义词为never。always等与not连用时，表示部分否定。如：
The rich are not always happy. 有钱的人并不总是快乐的。
◆usually意为“通常”，表示习惯性动作或状态，很少有例外。如：
We usually go to school at seven in the morning. 我们通常在早上七点上学。
◆Often意为“经常，时常”，表示反复性的动作或状态，中间有间断，不如usually那么频繁。其反义词是seldom。often在句尾时常被very或quite修饰。如：
It often rains here in April. 这儿四月份常下雨。
◆sometimes意为“有时”，频率不及often，表示动作偶尔发生，间断时间较长。其位置比较灵活，放在句首、句中、句末都可。如：
Sometimes we go to the cinema and at other times we go for a walk.
有时我们去看电影，有时我们去散步。
◆hardly具有否定意义，表示“几乎不、简直不”，除非特殊情况，否则不会发生。如：
The boy is so young that he could hardly understand it. 这个孩子太小了，不可能懂得这件事。
◆对上述频度副词提问时，用how often。如：
I write to my brother sometimes.
How often do you write to your brother？
【重点句型】
1. I go to the movies maybe once a month.
maybe adv. 大概；或许；可能
Maybe he knows the way to the zoo.也许他知道去动物园的路。
【辨析】maybe与may be
maybe副词，常位于句首作状语，意为“大概;或许;可能”,相当于perhaps，
He may be in the office. =Maybe he is in the office.他或许在办公室。
may be may是情态动词，may be为“情态动词+动词原形”结构，在句中作谓语，意为“可能是”。
Maybe she is a doctor. = She may be a doctor.
他可能在教室里。
Maybe he is in the classroom.
He may be in the classroom.
-他在教室里吗？--可能吧
--Is he in the classroom -- Maybe.
2. He plays at least twice a week.
at least 至少；不少于；起码
at least为固定短语，
其反义短语是at most，意为“至多；不超过”。
Teenagers need to sleep at least 8 hours every day.
You can borrow at most three books once.
3. How often do they stay up late
stay up是固定短语，stay up是不及物动词短语，其后不能接宾语。意为“熬夜；不睡觉”，与sit up同义。stay up late指 “熬夜到很晚，迟睡”。
eg：He stayed up too late last night.他昨天晚上熬夜到很晚。
例：我打算熬夜来完成论文。 I am going to stay up to finish my paper.
别熬夜到太晚，那对你的健康不利。
Don’t stay up too late. It’s bad for your health.
【拓展】
stay in/at 待在某地
例：他想要待在家。 He feels like staying at home.
stay out 待在户外；不在家
她妈妈不喜欢她在外面待太晚。
Her mother doesn’t like her staying out too late.
He stayed up to watch the football match last night.
他昨天晚上熬夜看了足球比赛。
It’s bad for your health to stay up late.
熬夜对你的身体不好。
He plays tennis at least twice a week.
他一周至少打两次网球。
at least是固定搭配，意为“至少；不少于；起码”。它的反义词组是at most，意为“至多；不超过”。
我每天至少花费两个小时写作业.
I spend at least two hours doing my homework every day.
现在教室里的人最多有20个.
