二、频度副词、短语用法及练习

一般现在时常常与always, usually, often, sometimes, seldom, hardly, never等频度副词连用，表示动作发生的频率。这些频度副词按发生频率的高低依次为：always→usually→often→sometimes→seldom→hardly→never。

频度副词在句中的位置比较灵活，但通常放在行为动词之前，系动词、情态动词或助动词之后。

1. always 意为“总是，一直”，这是频率最高的词，表示动作反复，状态持续，不间断。其反义词是never，意为“从不”。如果要变为否定句，应将always改为never才能全部否定。另外，当always与进行时态连用时，常表示“总是”，带有厌烦、不满或赞美等感情色彩。如：

Li Ping is always late for school. 李平上学总是迟到

The boy is always asking for money. 这个小男孩总是要钱。（表厌烦

Li Ping is never late for school. 李平上学从不迟到。（全部否定）

2. usually 意为“通常”，表示习惯性动作或状态，很少例外。如：

We usually go to school at seven in the morning.

我们通常在早上七点上学。

My mother and I usually go shopping on Sundays.

我和妈妈通常在星期天去买东西。

3. often 意为“经常，时常”，表示反复性的动作或状态，中间有间断。其反义词是seldom, 意为“很少，不常”。often在句尾时常被very或quite修饰。如：

I often chat with my friends under the big tree.

我经常在这棵大树下和朋友聊天。
