以上各词均为表示频率的副词，常在一般现在时中作状语，置于助动词或be动词后，实义动词之前。
always 意为“总是，一直”，表示动作的重复、状态的继续，中间从来不间断，表示的频率最高，达100％。如：
I always get up at 6:30 in the morning. (always=all the time)
usually 意为“通常”，表示习惯性的动作，所表示的频率低于always,约为90％。如：
He usually plays soccer after school.
often 意为“时常，经常”，表示动作的重复，中间有间断，所表示的频率比usually低，约为60％。如：
His father often has breakfast at home.
sometimes 意为“有时”，表示动作有时做，有时不做，所表示的频率约为30％。如：
She usually has lunch at home, but she has it sometimes.
hardly ever (=seldom)“很少、难得”，表示动作难得做一次，所表示的频率约为1－2％。如：
My father hardly ever goes to the movies because he is too busy.
never 意为“从不、决不”，表示动作从不发生，所表示的频率为零。如：

how often 意为“多久一次”。它主要是用来提问动作发生的频率，回答应该是频率副词（如：always, usually, often, sometimes等）或表频率的副词词组（如：once, twice, three times a week, every day, once a year 等）。如：

Some

three or four times

The Simple Present Tense 一般现在时
语法贯通
用法：
1.表示经常、反复发生的动作。常与一些表示频率的副词或短语连用。如：always, usually, often, hardly ever, never, every day( week, year…), on weekends( Sundays…), once a month 等。
如： His parents often go for a walk.
.
2.表示一个人的爱好、特长、职业、性格、能力等。 如： My brother likes swimming. Mary sings very well.
3.表示目前的状态或客观真理。如：
They are student. The earth goes around the sun.
1. 表示状态的be有三种形式，即：am, is, are。
2. 谓语动词为实义动词用：动词原形或动词的第三人称单数形式。
词形特点 变化规则 例词
以字母s， x， ch， sh， o结尾 在词尾加 -es relaxes; watches; goes
以辅音字母＋y结尾 变y为i，再加-es study studies
以元音字母＋y结尾 直接加-s即可 play plays
一般情况 在词尾加-s comes; looks
动词的第三人称单数构成
否定式及疑问式：
1.连系动词be( am, is, are),可直接在后面加not或其它否定词来构成否定句；将其置于句首，句末用问号即变为疑问句。
2.实义动词以原形来表示,助动词为do;但当主语为第三人称单数时，词尾加-s 或 –es, 助动词为does（注：凡用了does构成否定或疑问，原动词三单式必须恢复成原形）。如：
（1） John’s parents don’t like going out for a walk.
（2） Do they often swim in the afternoon
Yes, they do. / No, they don’t.
（3） What do you do every day
（4） I don’t want much to eat, I’m not hungry.
（5） Does he play soccer every day
Yes, he does. / No, he doesn’t.
