五、頻度副詞在否定句中的用法

在否定句中，有的頻度副詞位于否定詞之前或之后均可，而有的頻度副詞則必須位于否定詞之后，而還有的頻度副詞卻必須要位于否定詞。大致情況如下：

1. 頻度副詞usually和often可位于否定詞not之前或之后。如：

他們不常開(kāi)這樣的晚會(huì)。

正：They don’t often hold such parties.

正：They often don’t hold such parties.

星期日我們一般不在9點(diǎn)以前起床。

正：We don’t usually get up before nine on Sundays.

正：We usually don’t get up before nine on Sundays.

在否定句中，頻度副詞用于句中或句首，有時(shí)但會(huì)導(dǎo)致意思不同。如：

He doesn’t usually sleep for two days at a time. 他很少一連睡兩天。

Usually he doesn’t sleep for two days at a time. 他連續(xù)兩天不睡覺(jué)是常事。

2. 頻度副詞always總是位于否定詞之后，不可位于否定句之前。如：

Things are not always what they seem to be. 外表往往是靠不住的。

Silence must not always be read as consent. 沉默并不見(jiàn)得一定意味著同意。

We thoroughly understand each other, even if we don’t always agree. 我們彼此非常了解，雖然有時(shí)候也有一些分歧。

3. 頻度副詞sometimes總是位于否定詞之前，不可位于否定詞之后。如：

Jim is sometimes not very punctual. 吉姆有時(shí)不太準(zhǔn)時(shí)。

He is sometimes not satisfied with my work. 他有時(shí)對(duì)我的工作不滿意。

Debbie is sometimes not responsible for what she does. 戴比有時(shí)對(duì)她所做的事不負(fù)責(zé)任。

六、如何對(duì)頻度副詞提問(wèn)

對(duì)頻度副詞提問(wèn)，英語(yǔ)通常用how often。How often的本意是“多經(jīng)常”，通常譯為“多久”“隔多久”。如：

How often do you wash your hair? 你多長(zhǎng)時(shí)間洗一次頭發(fā)?

How often do you go to church? 你隔多久去做一次禮拜?

How often do you have a bad back? 你多長(zhǎng)時(shí)間腰痛一次?

How often do the buses run? 公共汽車(chē)隔多長(zhǎng)時(shí)間一班?

How often do you hear from your sister? 你多長(zhǎng)時(shí)間接到你姐姐一次信?
