***三***
1、 always、usually、often、sometimes、hardly ever和never
always、usually、often、sometimes、hardly ever和never是英語中最常見的頻度副詞。
***1***always 的頻度為100%，表示動作重複、狀態繼續，中間沒有間斷，意思是“總是”、“永遠地”。
The sun always rises in the east and sets in the west. 太陽總是東昇西落。
***2***usually 的頻度為70%左右，意為“通常”、“平常”，即很少有例外。
He usually goes to bed at ten o’clock. 他通常10點鐘睡覺。
***3***often 的頻度為50%左右，意為“常常”，但不如usually那麼頻繁，表示動作重複，中間有間斷。
He is often late for school. 他上學經常遲到。
***4***sometimes 的頻度為20%左右，意為“有時”，表示動作偶爾發生。可以位於句首，以示強調。多用於一般現在時。
It is sometimes hot and sometimes cold. 天氣忽冷忽熱。
Sometimes he does it this way and sometimes he does it that way.
他有時這樣做，有時那樣做。
***5***hardly ever 的頻度為5%左右，意為“幾乎不”、“偶爾”，表頻率，位置是“行前be後”。
I hardly ever go out these days. 這些天我幾乎不出門。
***6***never 的頻度為0，意為“從來不”、“永不”。
My parents are never late for work. 我父母上班從來不遲到。
【拓展】
***1***這些副詞在句子中的位置基本相同，一般放在助動詞、be動詞或情態動詞之後，行為動詞之前。即：“行”前“助***系***”後。
Peter is always late for school. Peter上學總是遲到。
I usually do my homework in the evening. 我通常在晚上做作業。
***2***hardly和hard
hardly和hard形式上很接近，但意義截然不同。
1***hard作形容詞時，意為“困難的;硬的;勤奮的;嚴厲的;苛刻的”。
hard作副詞時常用來表示程度，意為“努力地;猛烈地;劇烈地”。
This ground is too hard to dig. 這塊地太硬，挖不動。
They tried hard to succeed. 他們努力工作，以求得成功。
2***hardly是表頻率的副詞，意為“幾乎不;幾乎沒有”，相當於almost not。
There is hardly any coffee left.= There’s almost no coffee left.
幾乎沒有剩餘的咖啡了。
***3***sometimes、sometime、some time和some times
He was sometimes late for school. 他有時上學遲到。
He came here sometime. 他某個時候來過這裡。
He will stay there for some time. 他將在那裡待一段時間。
She came home some times. 她回了幾次家。
2、 exercise
***1***作不及物動詞，意為“鍛鍊、運動”。
— How often do you exercise? 你多久鍛鍊一次?
— I exercise every day. 我每天都鍛鍊。
***2***作不可數名詞，意為“鍛鍊、運動”，常與動詞take連用。
Exercise makes me keep healthy. 運動使我保持健康。
John likes to take exercise in the open air. 約翰喜歡在戶外鍛鍊。
***3***作可數名詞，意為“練習;操”。
We do morning exercises every day. 我們每天做早操。
We do English exercises to help us learn English well.
我們做英語練習以便學好英語。
3、 most
most表示“大部分，多半”的意思。
Most children like playing computer games. 大部分孩子喜歡玩電腦遊戲。
【拓展】 most與most of 的區別：
***1***most後可直接跟名詞***可數或不可數***，同時，也可接有形容詞修飾的名詞。
Most boys like playing football. 大部分男孩都喜歡踢足球。
I always spend most time learning English.我總是花大部分時間學習英語。
***2***most後不能直接跟有定冠詞、指示代詞或物主代詞所修飾的名詞，遇到這些情況用most of 代替most。
I spent most of my time learning to play the piano last year.
去年我把大部分時間都花在學彈鋼琴上了。
I did most of that difficult work. 那件困難的工作絕大部分都是由我做的。
***3***most of 後跟人稱代詞時，應用複數形式的人稱代詞賓格。
Most of them are going off to Guangzhou next week.
他們中的多數人都準備下星期去廣州。
***4***most 前有定冠詞時，可用來修飾多音節形容詞，表示最高階，意為“最”。
This is the most beautiful flower. 這是最漂亮的花。
但是，如果most前有不定冠詞a，則表示“非常;很”，相當於very。
She is a most beautiful girl. 她是個非常漂亮的姑娘。
4、 no
no是形容詞，意為“無，沒有”，一般用作定語，後接可數名詞或不可數名詞。相當於not…a/any。
I have no friends.=I don’t have a/any friend. 我沒有朋友。
