I．语言点精讲
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.
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.
4. 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）
