She is too tired.她一整天都在扫大街。她太累了。We have been waiting for you for two hours. We don't want to wait any longer.我们已经等你两个小时了。不想再等了。 三、常用句型1. 肯定句：“主语+have(has) been+动词的现在分词+其他.”例如：I have been sitting here all the afternoon.我在这儿坐了一下午。He has been collecting all kinds of stamps since he was ten years old.自十岁起他就开始收集各式各样的邮票。2. 否定句：“主语+have(has) not been+动词的现在分词+其他.”例如：They haven't been meeting each other for five years.他们有五年没见面了。He hasn't been teaching here these years.这些年他并没有一直在这儿教书。3. 一般疑问句：“Have(Has) + 主语 + been + 动词的现在分词？”其肯定回答：“Yes, 主语 + have(has).”否定回答：“No, 主语 + haven't (hasn't).”【例如】： Have you been studying for the English test today?你今天一直在准备英语测试吗？ Yes, I have. / No, I haven't.是的。 / 不，我没有。 Has Daniel been skating for two years?丹尼尔滑冰已经有两年了吗？ Yes, he has. / No, he hasn't.是的。/ 不，他没有。4. 特殊疑问句：“ 特殊疑问词 + 一般疑问句？”【例如】：What book have you been reading recently? 最近你在看什么书？ How has your uncle been getting on with his work? 你叔叔的工作进展得怎么样？四、注意事项有些不能用现在进行时的动词，如 be, have, like, love, know, see, hear 等，同样也不能用现在 完成进行时，而应用现在完成时。例如：The poor woman has been ill for a long time. 那可怜的妇人已经病了好久了。Have you seen her parents these days?这些天你看见她的父母了吗？ 时态对比1. 现在完成进行时及现在进行时比较：现在完成进行时强调某一动作从过去一直延续到现在；而现在进行时只指目前正在发生的动 作。试比较：Susan has been reading that storybook since last night.从昨晚开始苏珊就一直在看那本故事书。 Susan is reading a storybook now. 苏珊正在看一本故事书。2. 现在完成进行时和现在完成时比较：有些动词(如：work, study, live, teach 等)用现在完成进行时及现在完成时表达的意思差不多。试 比较：The teacher has been teaching at this school for ten years.十年来，那位老师一直在这所学校教书。The teacher has taught at this school for ten years.那位老师在这所学校已经教了十年书了。英语中的多数动词在这两种时态中表示不同的含义。现在完成时如果不带表示一段时间的 状语，就只能表示动作的完成，而现在完成进行时则表示动作的延续。试比较：They have built a new lab. 他们建造了一幢新的实验室。(表示动作的完成) They have been building a new lab (these years).他们(这几年)一直在建造一幢新的实验室。(无论用时间状语还是不用时间状语，都表示动作 的延续)Step IV Practice （Using Structures in Workbook） Step V HomeworkAsk the students finish Exercise in Word Study Part.
