5、 They eat chocolate at home. (never),She always gets up at 7:00 am.,They never eat chocolate at home.,三、用法,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 i

6、s 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）,He is always thinking of others. 他总是想着别人。（赞叹） She is always asking silly questions. 她老是问些愚蠢的问题。（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 t

8、riends 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： 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。,5. hardly ever意为“很少

9、，几乎不”，表示否定意义。如： The little girl hardly ever goes out. 这个小女孩很少外出。 He hardly ever gives his wife a present, does he? 他不常给妻子送礼物，是吗？,6. 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。 Better late than never. 谚语 迟到（迟做）总比不来（不做）好。,另外

10、，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. 我们通常一个月看四次电影。,针对上面所说的频度副词和表示“在某段时间内某种动作的次数”的状语提问时，都要用how often。 换句话说，如果要回答由how often提问的句子，我们通常要用频度副词或诸如every

13、ly come to see her grandpa?,解析：How often does。划线部分four times a month涉及频率，应用How often提问，同sometimes、usually、often、always、once、twice、once a week、twice a year等。句中动词comes为单三式，改为疑为句时应添加助动词does，动词还原。,（2012菏泽中考）- Steve, _ do you play basketball after school? - Twice a week.
