一、頻度副詞的概念與用法

頻度副詞是指表示動(dòng)作發(fā)生的次數(shù)副詞，常見有的never, seldom, sometimes, frequently, often, usually, always 等。頻度副詞通常位于實(shí)義動(dòng)詞之前，動(dòng)詞be、助動(dòng)詞、情態(tài)動(dòng)詞等之后。如：

We often get together. 我們常常聚會。

Jane usually goes to work by bike. 簡通常騎自行車上班。

He sometimes goes there on business. 他有時(shí)到那里出差。

He can never understand. 他永遠(yuǎn)也不會明白的。

I was never very good at maths. 我的數(shù)學(xué)從來不好。

Ishallalways remember this. 我將永遠(yuǎn)記住這一點(diǎn)。

You have often been told not to do that. 多次告誡過你別干那事。

注：如果有兩個(gè)助動(dòng)詞，頻度副詞通常放在第一個(gè)助動(dòng)詞后面。如：

We have never been invited tooneof their parties. 他們聚會，一次也沒邀請過我們。

Shemustsometimes have wanted to run away. 她有時(shí)候一定想到過要逃走。
