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。Li Ping is never late for school. 李平上学从不迟到。（全部否定）Li Ping is not always late for school.李平上学不总是迟到。（部分否定）
The boy is always asking for money. 这个小男孩总是要钱。（表厌烦）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：The boys often eat noodles and the girls sometimes eat them.男生经常吃面条，女生有时吃。
I often chat with my friends under the big tree.我经常在这棵大树下和朋友聊天。
He writes to his friends quite often. 他常给他的朋友写信。4. sometimes意为“有时”，表示动作偶尔发生，间隔较长。其位置比较灵活，放在句首、句中、句末都可。如：
2
Sometimes we go to the cinema and at other times we go for a walk.有时我们去看电影，有时我们去散步。
I sometimes watch TV in the evening. 我有时晚上看电视。My father has lunch in the factory sometimes.我父亲有时在工厂吃午饭。5. seldom 意为“很少，不常”，表示否定意义。
如： The little girl seldom goes out. 这个小女孩很少外出。He seldom gives his wife a present, does he?他不常给妻子送礼物，是吗？
6. hardly具有否定意义，表示“几乎不、简直不”，除非特殊情况，否则不会发生。如：The boy is so young that he could hardly understand it.这个孩子太小了，不可能懂得这件事。7. never意为“从来不，从来没有”，也表示否定意义，它表示从未发生的动作或情况，没有例外。如：
The boys never eat chocolate and the girls seldom eat it.男生从不吃巧克力，女生很少吃。
*另外，once a year (每年一次), twice a week (每周两次), three times a day (一天三次), every Saturday afternoon（每星期六下午）等，这些时间状语也表示频率，它们可以和频度副词用在同一个句子中，表达上没有重复。如：We usually go to the cinema four times a month.
对这些频度副词或短语进行提问，都用疑问词how often，表示“每（隔）多长时间做一次”的意思。如：
