八年级英语上册知识点(三)
1、 always、usually、often、sometimes、hardly ever和never
always、usually、often、sometimes、hardly ever和never是英语中最常见的频度副词。
(1)always 的频度为100%，表示动作重复、状态继续，中间没有间断，意思是“总是”、“永远地”。
The sun always rises in the east and sets in the west. 太阳总是东升西落。
(2)usually 的频度为70%左右，意为“通常”、“平常”，即很少有例外。
He usually goes to bed at ten o’clock. 他通常10点钟睡觉。
(3)often 的频度为50%左右，意为“常常”，但不如usually那么频繁，表示动作重复，中间有间断。
He is often late for school. 他上学经常迟到。
(4)sometimes 的频度为20%左右，意为“有时”，表示动作偶尔发生。可以位于句首，以示强调。多用于一般现在时。
It is sometimes hot and sometimes cold. 天气忽冷忽热。
Sometimes he does it this way and sometimes he does it that way.
他有时这样做，有时那样做。
(5)hardly ever 的频度为5%左右，意为“几乎不”、“偶尔”，表频率，位置是“行前be后”。
I hardly ever go out these days. 这些天我几乎不出门。
(6)never 的频度为0，意为“从来不”、“永不”。
My parents are never late for work. 我父母上班从来不迟到。
【拓展】
(1)这些副词在句子中的位置基本相同，一般放在助动词、be动词或情态动词之后，行为动词之前。即：“行”前“助(系)”后。
Peter is always late for school. Peter上学总是迟到。
I usually do my homework in the evening. 我通常在晚上做作业。
(2)hardly和hard
hardly和hard形式上很接近，但意义截然不同。
1)hard作形容词时，意为“困难的;硬的;勤奋的;严厉的;苛刻的”。
hard作副词时常用来表示程度，意为“努力地;猛烈地;剧烈地”。
This ground is too hard to dig. 这块地太硬，挖不动。
They tried hard to succeed. 他们努力工作，以求得成功。
2)hardly是表频率的副词，意为“几乎不;几乎没有”，相当于almost not。
There is hardly any coffee left.= There’s almost no coffee left.
几乎没有剩余的咖啡了。
(3)sometimes、sometime、some time和some times
He was sometimes late for school. 他有时上学迟到。
He came here sometime. 他某个时候来过这里。
He will stay there for some time. 他将在那里待一段时间。
She came home some times. 她回了几次家。
2、 exercise
(1)作不及物动词，意为“锻炼、运动”。
— How often do you exercise? 你多久锻炼一次?
— I exercise every day. 我每天都锻炼。
(2)作不可数名词，意为“锻炼、运动”，常与动词take连用。
Exercise makes me keep healthy. 运动使我保持健康。
John likes to take exercise in the open air. 约翰喜欢在户外锻炼。
(3)作可数名词，意为“练习;操”。
We do morning exercises every day. 我们每天做早操。
We do English exercises to help us learn English well.
我们做英语练习以便学好英语。
3、 most
most表示“大部分，多半”的意思。
Most children like playing computer games. 大部分孩子喜欢玩电脑游戏。
【拓展】 most与most of 的区别：
(1)most后可直接跟名词(可数或不可数)，同时，也可接有形容词修饰的名词。
Most boys like playing football. 大部分男孩都喜欢踢足球。
I always spend most time learning English.我总是花大部分时间学习英语。
(2)most后不能直接跟有定冠词、指示代词或物主代词所修饰的名词，遇到这些情况用most of 代替most。
I spent most of my time learning to play the piano last year.
去年我把大部分时间都花在学弹钢琴上了。
I did most of that difficult work. 那件困难的工作绝大部分都是由我做的。
(3)most of 后跟人称代词时，应用复数形式的人称代词宾格。
Most of them are going off to Guangzhou next week.
他们中的多数人都准备下星期去广州。
(4)most 前有定冠词时，可用来修饰多音节形容词，表示最高级，意为“最”。
This is the most beautiful flower. 这是最漂亮的花。
但是，如果most前有不定冠词a，则表示“非常;很”，相当于very。
She is a most beautiful girl. 她是个非常漂亮的姑娘。
4、 no
no是形容词，意为“无，没有”，一般用作定语，后接可数名词或不可数名词。相当于not…a/any。
I have no friends.=I don’t have a/any friend. 我没有朋友。
