What does she do on weekends? 她周末做什么？ （1）询问某人在什么时间做某事在英语中用What do / does sb. do.? 来构成疑问。请注意助动词随着人称的变化而发生改变。如： <1>What does she do after school? 她放学后做什么？ <2>What do they do on Mid-Autumn Festival? 他们中秋节做什么？ （2）这种问题要注意问时间时介词的用法和助动词随人称的改变，他们的回答用一般现在时回答，特别要注意主语是第三人称单数时，动词要变形，如上面两个问题可以这样回答： <1>She usually goes to the gym. 她通常去体育馆。 <2>They eat moon-cakes. 他们吃月饼。2.I often go to the movies .频度副词 always, usually, often, sometimes, hardly和never是英语中最常见的频度副词，它们在句中的位置大致相同：通常放在行为动词之前，系动词be、助动词和情态动词之后。但它们所表示的含义及频度是各不相同的。 （1）always的频度为100%，表示动作重复、状态继续，中间没有间断，意思是“总是”、“永远地”。例如： The sun always rises in the east and sets in the west. 太阳总是东升西落。 Customers are always right. 顾客永远是对的。 always与进行时态连用，并不强调动作正在进行，而是表示说话人的“赞扬”、“不满”、“厌烦”等情绪，有强烈的感情色彩。例如： She is always thinking of how she can do more for people. 她总是在考虑怎样为人们多做些事。（表示赞扬） He was always asking for money. 他总是要钱。（表示厌烦） She is always asking for leave. 她总是请假。（表示不满） always与not连用，表示部分否定，意思是“不总是”。例如： The rich are not always happy. 有钱人未必总是幸福的。 （2）usually的频度为70%左右，意为“通常”、“平常”，即很少有例外。例如： He usually goes to bed at ten oclock. 他通常10点钟睡觉。 （3）often的频度为50%左右，意为“常常”，但不如usually那么频繁，表示动作重复，中间有间断。例如： He is often late for school. 他上学经常迟到。 very often语气比often重，常位于句首或句末。例如： He doesnt go to London very often. 他不常去伦敦。 （4）sometimes的频度为20%左右，意为“有时”，表示动作偶尔发生。可以位于句首，以示强调。例如： It is sometimes hot and sometimes cold. 天气忽冷忽热。 Sometimes he does it this way and sometimes he does it that way. 他有时这样做，有时那样做。 （5） hardly的频度为5%左右，意为“几乎不”、“简直不”，常和ever连用表示强调。例如： I hardly ever go out these days. 这些天我几乎不出门。 （6）never的频度为0，意为“从来不”、“永不”。例如： My parents are never late for work. 我父母上班从来不迟到。 3.
