1. Let's look at the following words and their usage.

 频度副词:always, usually, often, sometimes, hardly和never是英语中最常见的频度副词,它们在句中的位置大致相同:通常放在行为动词之前,系动词be、助动词和情态动词之后。但它们所表示的含义及频度是各不相同的。

(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”。例如:

 The sun always rises in the east and sets in the west. 太阳总是东升西落。

Customers are always right. 顾客永远是对的。

 ▲always与进行时态连用,并不强调动作正在进行,而是表示说话人的“赞扬”、“不满”、“厌烦”等情绪,有强烈的感情色彩。例如:

She is always thinking of how she can do more for people.  她总是在考虑怎样为人们多做些事。(表示赞扬)

He was always asking for money. 他总是要钱。(表示厌烦)

She is always asking for leave.  她总是请假。(表示不满)

▲always与not连用,表示部分否定,意思是“不总是”。例如:

The rich are not always happy. 有钱人未必总是幸福的。

(2)usually的频度为70%左右,意为“通常”、“平常”,即很少有例外。例如:

 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。例如:

He is often late for school. 他上学经常迟到。

▲very often语气比often重,常位于句首或句末。例如:

He doesn’t’t go to London very often.  他不常去伦敦。

(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。例如:

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。He sometimes goes to movies on Friday evening.   他有时周五晚上去看电影。

(5) hardly的频度为5%左右,意为“几乎不”、“简直不”,常和ever连用表示强调。例如:

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”。例如:

 My parents are never late for work.我父母上班从来不迟到。
