英语频度副词复习要点(大全)
在否定句中,有的频度副词位于否定词之前或之后均可,而有的频度副词则必须位于否定词之后,而还有的频度副词却必须要位于否定词。大致情况如下:
1. 频度副词usually和often可位于否定词not之前或之后。如:
他们不常开这样的晚会。
正:They don’t often hold such parties.
正:They often don’t hold such parties.
星期日我们一般不在9点以前起床。
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,频度副词用于句中或句首,有时但会导致意思不同。如:
He doesn’t usually sleep for two days at a time. 他很少一连睡两天。
Usually he doesn’t sleep for two days at a time. 他连续两天不睡觉是常事。
2. 频度副词always总是位于否定词之后,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. 沉默并不见得一定意味着同意。
We thoroughly understand each other, even if we don’t always agree. 我们彼此非常了解,虽然有时候也有一些分歧。
3. 频度副词sometimes总是位于否定词之前,不可位于否定词之后。如:
Jim is sometimes not very punctual. 吉姆有时不太准时。
He is sometimes not satisfied with my work. 他有时对我的工作不满意。
Debbie is sometimes not responsible for what she does. 戴比有时对她所做的事不负责任。
六、如何对频度副词提问
对频度副词提问,英语通常用how often。How often的本意是“多经常”,通常译为“多久”“隔多久”。如:
How often do you wash your hair? 你多长时间洗一次头发?
How often do you go to church? 你隔多久去做一次礼拜?
How often do you have a bad back? 你多长时间腰痛一次?
How often do the buses run? 公共汽车隔多长时间一班?
How often do you hear from your sister? 你多长时间接到你姐姐一次信?
