Whose birthday is it? 05 考点大全 Language points Point 1 对频率提问，How often + 助动词 do (does 或 did) + 主语 + do sth. ? 及回答： 一周一次 once a week 一月两次 twice a month 一月三次three times a month 每天 every day 用次数+时间段回答， “once/twice/three times… a day/week/month/year…” 用时间短语回答， “every day/week/month/year” 3.用频度副词回答，如：always, usually, often, sometimes, hardly ever,never. 【详解】How often + 助动词 do (does 或 did) + 主语 + do sth. ? 是对频率（多久一次）进行提问。疑问词 how often (在这里助动词 do, does, 或 did 是起疑问的作用) 与一般现在时或一般过去时连用，回答一般用表频率的副词 always, usually, often, sometimes, never 等或者是“数次 + 一段时间”，如 once/twice a month, three times a month, every year, every week 等。 How many times 对次数进行提问，其答语为 once, twice, three times 等表示次数的单词或短语。 e.g. 你多久上一次钢琴课？ How often do you have piano lesson? 你一周上几次钢琴课？ How many times do you have piano lessons a week? 2.How long… 多久… How long can I keep this dictionary? 　　我能借这字典多久？ 3. How soon… 多久(之后)… How soon will your father come back? 　你爸爸多久后回来？ 4.How much/many… 多少/多少钱… How much water is there in the bottle? You can keep it for three weeks. He ’ll come back in three days. 【拓展】 1.How far… 多远… How far is it from your home to the zoo? 从你家到动物园有多远． 2. once/twice a week once a week是表示频率的短语，意为“一周一次”，常用来回答how often的提问。其中once作副词，意为“一次”。 —How often do you go hiking? —Once a week. twice作副词，在此处意为“两次”。twice a month/year意为“一月/年两次”，表示频率。 I play chess at least twice a week. Please think twice before you hand in your paper. Point 2 once, twice, three times等次数的表达法。 1) 这三个词都表示次数，once是一次，twice是两次，除了一次，两次，其他的次数表达都是数字 + times 三次是_____________ 五次是_____________ three times five times 2) 这些表次数的词后与一段时间连用，表示动作多长时间发生几次，即动作的频率。 次数表达法 表示次数应注意，time后面加-s； 一次、两次很特殊，once、twice要牢记。 Point 3 1）be good at sth/doing sth…表示“擅长于……；精通……”，后面可接名词或动词的ing形式。例如：     Mr. Gu is good at languages. He can speak eight languages. 顾先生精通多种语言，他会说八种语言。 I'm not very good at it! 2） Are you good with old people? 你善于跟老人打交道吗？ 此处的be good with sth/sb表示“善于应付……的；对……有办法”。如 The teacher is very good with children.    这位老师对孩子很有一套。 3) be good for 对……有益 be bad for“对……有害”。 Eating too much is bad for your health. 吃太多对你的健康有害。 You should do more exercise. It is good for your health. 你应该多运动。那对你的健康有益。 后接名词、代词或动词-ing形式。 【辨析】由“be good + 介词”构成的其他短语: be good to 对……友好 相当于 be friendly / kind to,后面一般接 sb. be good at 擅长…… 后跟名词、代词或动词-ing形式作宾语，同义短语为 do well in be good with 善于应付……; 对……有办法 后接 sb.或 sth. be good for 对……有益 后接名词、代词或动词-ing形式。 Can I join your game this weekend? Point 4 Can的用法 (1) 它是辅助动词帮助说明能力、意愿 等的情态动词，它不随主语人称的变化而变化 。 e.g: I can sing. He can swim. (2) 变否定句直接在can后加“not”. e.g: I can not dance. I can’t dance. (3)变疑问句直接把can提前 e.g: Can you dance ? What can you do ? 【即学即练】填空题。 1. ____ you swim? Yes, I can. 2. --Can your father play the guitar? --No, he ______. 3. --Can Lucy and Alice dance? --Yes, _____ can. Can can’t they 【辨析与拓展】 join & take part in 1. join v. 参加；加入；作……成员 join + 团体/组织，表示成为…...的一员 join the army 参军 join the Party入党 join the club 加入这个俱乐部 2. take part in 参加(群众性活动、会议等) 1.

I usually watch TV. I often play basketball. I sometimes go to movies. I hardly ever do housework. He is never late for school. 100% 0% usually often sometimes never always hardly ever 总是 通常 常常 有时 几乎不曾 从未 46 结论：1 频率副词在句中通常放在实义动词之 前, be动词或助动词之后。 主语+频率副词+动词 频度副词通常放在动词前面，若句子里有情态动词、助动词或系动词be,则放在这类动词（第一个）的后面。例如： It's always interesting to watch other people show their talents. Why do people usually make resolutions? When we watch movies about the future, we sometimes see robots. They hardly ever watch TV. Fewer people will do such jobs in the future because they are boring, but robots will never get bored. 2 频率副词所表示的含义和频率是不同的, 从高到低依次是： always usually often sometimes hardly ever never 100% 总是 80%  通常  60% 经常  40% 有时 20% 很少,几乎不 0 从不 47 sometimes：频度副词，意为“有时”，表示动作发生的不经常性，多与一般现在时连用，它可位于句首、句中或句末，对它提问用how often。 some times：名词短语，意为“几次；几倍”，其中time是可数名词，对它提问用how many times。 【拓展】 辨析：sometimes, some times, sometime与some time some time：名词短语意为“一段时间”，表示“一段时间”时，句中谓语动词常为延续性动词。对它提问用how long。 Sometime：副词，意为“某个时候”，表示某个不确切或不具体的时间，常用于过去时或将来时，对它提问用when。 __________ I get up very late.
