PB中 main window（主窗口）popup window（d出窗口）respond window（响应窗口）有什麼不同呢

Main窗口是主窗口，独立于其他窗口，可以调用其他窗口，被其他窗口覆盖，也可以覆盖其他窗口。它包括控制菜单、控制按钮、显示区域。主窗口都有边框和标题栏，一般都允许用户调节其大小。但是在主窗口中，工具条是不能显示的。在应用程序中，一般首先打开的是Main类型的窗口，然后用主窗口调用其他的窗口，来共同完成特定的任务。应用对象程序关闭时，这种类型的窗口不会自动关闭，除非用户亲自关闭。所以，如果在一个应用中除了主 *** 作窗口外的其他地方使用了Main类型的窗口，一定在应用关闭之前关闭它们，否则会造成程序虽然结束，但还零星有几个窗口在运行的有趣局面。

Response窗口是模式窗口，在继续执行程序之前必须对其做出响应，否则程序无法继续运行。一般用于处理特别重要的信息，如：让用户确认选择、提示当前的错误信息、输入下步必需数据等。这种类型的窗口没有边框和最大最小按钮，不能改变大小，但能够拖动它改变位置，它的位置是相对整个屏幕而言的。PB提供了预定义的Response窗口，如messagebox。提示重要信息时，经常使用这种类型的窗口，要避免业务处理类型的窗口使用这种类型。因为某些控件上可能会自动以信息窗口的形式显示一些提示信息，当这样的控件是在Response类型的窗口上时，应用程序容易导致用户计算机死机。

Popup窗口一般用来提供一些辅助信息。它和父窗口关系紧密，但可以浮动到父窗口的外部。当父窗口最大或最小化时，它也相应的被最大或最小化，父窗口关闭时，它也相应的自动关闭。也可以用鼠标调节其大小。Popup类型的窗口可以拥有主窗口的所有组件。这四种类型的窗口特点如下表所示。

五一国际劳动节

五一国际劳动节wǔ yī guó jì láo dòng jié亦称"五一节",定在每年的五月一日。它是全世界无产队级、劳动人民的共同节日。

Labor's Day is on May 1st Labor's Day is an international day for workers Working is glorious, and we should respect workers The Labor's Day is workers' holiday and workers can enjoy themselves to their heart's content Many people choose to travel And some others will go to the cinema Some will go to parks And others will stay at home

此节源于美国芝加哥城的工人大罢工1886年5月1日,芝加哥的二十一万六千余名工人为争取实行八小时工作制而举行大罢工,经过艰苦的流血斗争,终于获得了胜利为纪念这次伟大的工人运动,1889年7 月第二国际宣布将每年的五月一日定为国际劳动节这一决定立即得到世界各国工人的积极响应1890年5月1日,欧美各国的工人阶级率先走向街头,举行盛大的示威游行与集会,争取合法权益从此,每逢这一天世界各国的劳动人民都要集会,游行,以示庆祝

为纪念这次伟大的工人运动,1889年7月，在恩格斯组织召开的第二国际成立大会上宣布将每年的五月一日定为国际劳动节，简称“五一”。这一决定立即得到世界各国工人的积极响应。1890年5月1日,欧美各国的工人阶级率先走向街头,举行盛大的示威游行与集会,争取合法权益。从此,每逢这一天,世界各国的劳动人民都要集会、游行,以示庆祝。

中国人民庆祝劳动节的活动可追溯至1918年。这一年,一些革命的知识分子在上海、苏州、杭州、汉口等地向群众散发介绍“五一”的传单。

1920年5月1日,北京、上海、广州、九江、唐山等各工业城市的工人群众浩浩荡荡地走向街市、举行了声势浩大的游行、集会。李大钊专门在《新青年》上发表了《“五一”运动史》，介绍“五一”节的来历和美法等国工人纪念“五一”的活动，号召中国工人把这年的“五一”作为觉醒的日期。陈独秀也为庆祝这个节日发表了《上海厚生纱厂湖南女工问题》一文，揭露资本家剥削工人剩余价值的真相。陈独秀又在上海船务栈房工界联合会作了《劳苦者的觉悟》的演说，阐明了“劳动创造世界”。“做工的人最有用最贵重”的观点。在北京，一些青年外出宣传，散发《五月一日劳工宣言》，唤起工人为反对剥削、争取自身权利而斗争。这是中国首次纪念“五一”国际劳动节的活动，也是中国历史上的第一个“五一”劳动节。

新中国成立以后,中央人民政府政务院于1949年12月将5月1日定为法定的劳动节,是日全国放假一天。每年的这一天,举国欢庆,人们换上节日的盛装,兴高采烈地聚集在公园、剧院、广场,参加各种庆祝集会或文体娱乐活动,并对有突出贡献的劳动者进行表彰。

1920年5月1日,北京,上海,广州,九江,唐山等各工业城市的工人群众浩浩荡荡地走向街市,举行了声势浩大的游行,集会,这就是中国历史上的第一个五一劳动节放后,中央人民政府政务院于1949年12月将五月一日定为法定的劳动节,是日全国放假一天节日,举国欢庆,人们换上节日的盛装,兴高采烈地聚集在公园,剧院,广场,参加各种庆祝集会或文体娱乐活动,并对有突出贡献的劳动者进行表彰

1886年5月1日芝加哥城的工人大罢工

5月1日,国际劳动节,它是全世界工人阶级斗争的历史纪念,每个国家都很重视它,尤其是美国,加拿大,南非事件起因是, 1880年美国工人游行集会要求8小时工作制1884年,联邦贸易组织通过了一项解决方案,以立法的形式规定从1886年5月1日开始执行每日8 小时工作制,但此后,工人们仍然被强迫每天工作10小时,12小时,甚至14小时,这使得该项立法明有实亡,而各地的联邦首脑对此却表示出十分冷淡和不友好的态度,于是一场为争取8小时工作的罢工开始了

世界各国过"五一" 庆祝特色各千秋

一年一度的“五一”国际劳动节又到了，为了纪念这个全世界劳动人民团结战斗的节日，世界各国一般都会举行相应的庆祝活动。不过，并不是所有国家都将5月1日定为劳动节，那些同过“五一”的国家，具体的庆祝方式和习惯也大不相同，我们不妨一起来看看其他一些国家是怎么度过劳动节的。

美国：劳动节发源地不过“五一”

劳动节起源于美国。19世纪80年代，美国资产阶级为了进行资本积累，对工人阶级进行残酷的剥削压榨，他们用各种手段，迫使工人每天从事长达12到16小时甚至更多时间的劳动。美国广大工人逐渐认识到，为了保障自己的权利，必须起来进行斗争。

从1884年开始，美国先进的工人组织通过决议，要为实现“每天工作8小时”而战斗，并提出“8小时工作；8小时休息；8小时娱乐！劳动者创造全部财富！”等口号。

1886年5月1日，美国芝加哥的工人举行大罢工。那一天，以芝加哥为中心，美国全国约35万工人参加了罢工和游行，要求改善劳动条件，实行8小时工作制。这场斗争震撼了整个美国。工人阶级团结战斗的强大力量，迫使资本家做出了让步，美国工人的这一大罢工取得了胜利。

1889年7月，由恩格斯领导的第二国际在巴黎举行代表大会。为了纪念美国工人的这次“五一”大罢工，会议通过决议，将每年的5月1日定为国际劳动节。从此，世界各国的工人团体在这一天举行盛大庆祝活动，许多国家还放假一天。

但是，特殊的是，美国政府后来在设立劳动节时，自行规定每年9月的第一个星期一为劳动节，所以美国人的劳动节不在5月，而在9月。

每逢9月的劳动节，美国人可以放假一天，全美各地的民众一般都会举行游行、集会等各种庆祝活动，以示对劳工的尊重。在一些州，人们在游行之后还要举办野餐会，热闹地吃喝、唱歌、跳舞。入夜，有的地方还会放焰火。

俄罗斯：游行、集会、娱乐一个都不少

自国际上设立劳动节以来，俄罗斯一直比较重视这个特别的节日。“五一”这天，俄罗斯全国放假，并举行各种庆祝活动及群众性游行。

过去，上述活动主要是由政府组织，游行队伍中包括各企业、机关的代表。现在，除政府统筹的庆祝活动外，各种不同政见的非政府组织、劳工团体，都会在这一天自发举行各种庆祝活动，既可以借这个机会充分阐述各自的政见，又能扩大本组织的影响。

一般来说，“五一”游行的队伍要先穿过城市的主要街道、广场，最后在古老的或者宽阔的中心广场举行大型集会和庆典。同时，俄罗斯各地的各种俱乐部还会举行内容丰富、色彩缤纷的娱乐活动，人们的节日情绪很高。

日本：劳动节逢“黄金周”

日本是一个节日比较多的国家，5月1日前后的节日就很多，如4月29日植树节、5月3日宪法纪念日、4日国民假日、5日儿童节，这些假日连起来，一般日本人至少有一周休息时间，最长的甚至达11天。

对工薪阶层来说，这个长假的意义真是不同寻常。因此，在日本，劳动节专门的庆祝活动日渐被“五一黄金周”所取代。而且从4月29日开始，日本就已经进入了“黄金周”。

日本全国的许多饭店、温泉等娱乐设施，纷纷在“五一”前打出各种广告招揽游客，普通旅馆的房间价格也比平时提高一倍以上。

今年4月29日，日本成田机场迎来了假日的第一个高峰，当天从这里出国的游客超过4万人，预计“黄金周”期间该机场运送旅客将达到81万人。许多游客选择到夏威夷、塞班岛、中国和东南亚等地旅游。

加拿大：9月劳动节标志夏天结束

同为北美国家，加拿大与美国一样也是在每年9月的第一个星期一庆祝劳动节。在渥太华、多伦多等城市，每年劳动节时都会举行游行和集会，以此表彰工会组织下的工人对加拿大社会所做出的贡献。

另外，比较与众不同的是，在大多数加拿大人的概念中，这个9月的劳动节标志着夏天的结束。一般情况下，家长们会利用劳动节的假期给孩子买新学期的学习用品，商家也往往借机促销文具。

泰国、秘鲁：放假一天

泰国于1932年首次颁布劳工条例，随后将每年的5月1日确定为国家的劳动节，以此嘉奖辛勤工作的劳动者。这一天，泰国全国统一放假一天，在首都以及一些大城市会有相关的庆祝活动，不过规模一般都不会太大。

和泰国的情况比较类似，南美国家秘鲁也规定5月1日为国家的劳动节，而且全国放假一天。

意大利：不庆祝不放假

英国、法国等欧洲国家都将“五一”确定为劳动节，不少国家都放假一天，还有的国家则根据情况将公共假期放在5月的第一个星期一。

不过，和世界大多数国家不太一样的是，意大利尽管承认“五一”国际劳动节，政府也表示尊重劳工，但一般人并不举行专门的庆祝活动，也没有全国性的“五一”假期

同学们在做听力选择题的时候，很想知道解答选择题有什么技巧？雅思培训周末班指出，听力考试题目中，我们多多少少的可以看出来一些规律。下面就带大了解做听力选择题时可以用到的一些实用的原则。 1 客观事实原则 顾名思义，客观事实原则指的就是正确选项是符合客观事实规律的，而非让人一眼看过去就觉得违背常理。在一些选项中，如果考生发现了某选项其不符合客观真理或者常识，在审题过程中，可以先将其排除。如C4T3S4中的Question 38： 38 Most sharks are caught in A spring B summer C winter 听力原文为：The majority of sharks are caught during the warmest months, from November to February 正确答案：B 在笔者授课的过程中发现，大多数的考生是可以抓到听力原文中的from November to February这个月份的，但是，有过半的考生会将答案选成C winter。究其原因，不外乎是因为听的时候没有很多时间考虑，大部分人还是听到11月到2月个反应就是北半球的冬天，而忽视了背景是澳大利亚。 但是，如果考生在检查或者誊写答案的时候能够反应过来澳大利亚的11月份是夏天的开始，这个时候是完全可以把答案改成B的，因为这是符合客观事实的。因此，笔者建议考生，在审题过程中，可以尝着去看一下选项中有无符合大认知规律的客观真理，哪怕没有办法把答案直接选出来，也可以在一定程度上帮大缩小选项范围。 2 对性原则 对性的原则在听力选择题中也是相当好用的一个规则，尤其是在选择题目较多时，它可以帮助考生缩小选项范围，节省考生审题时间。它指的是如果考生在选项中发现一些表示对意义的词（如must，all，no，only等）的话，那么此选项基本上是可以排除的。 其依据是，既然雅思考是基于现实生活场景的，它里面的内容通常也和我们日常说话的习惯是相似的，而正常情况下，我们说话也都会留有一些余地，不会事事对。我们看一下例题： What TWO disadvantages of the questionnaire form of data collection do the students discuss A The data is sometimes invalid B Too few people may respond C It is less likely to reveal the unexpected D It can only be used with literate population E There is a delay between the distribution and return of questionnaires (C4T2S3) 在上题的D选项中，它表达的意思是问卷调查只能在受过教育的人群中使用。事实真的是这样吗？不知道大有没有发现，通常情况下，对性原则是可以和客观事实原则一起使用的，因为如果出现了表示对意义的词的时候，大多数情况下，那句话所表达的意思也会与客观规律或者常识相背离。 就如上题，如果某些调查问卷是针对于七八十岁受教育水平率相对较低的年龄层，那调查人员要怎么办呢？难道要放弃这个调查项目吗？答案一定是否定的。就算调查对象不识字，调查人员也是可以读给对方听，然后在收到对方回答之后帮对方填写的。因此D选项在审题过程中就是可以排除的。由此可见，考生在预测阶段，可以利用此原则进行排除。 3 主题一致原则 此原则指的是如果在三个选项中，考生发现其中两个选项讲的是同一方向，而另一个选项所讲内容与其他两选项无任何关系的时候，那么同方向的两个选项一定会二选一，同时排除那个特的选项。 这个原则单看的时候只是可以帮考生排除干扰项，和上述两个原则一样。然而，如果将此原则与对性原则相结合，那么考生是可以直接将正确答案选出来的。其用法为：考生在排除了与其他两选项主题不一致的那个选项之后，再去看一下剩余的两个选项有没有哪一个是含有表示对意义。 以上就是雅思培训周末班关于雅思听力选择题解答方法的介绍，总而言之，雅思听力考试的题型如何变化，我们都能从中找出它的“套路”，正确解题，毕竟雅思考是基于真实的生活场景孕育而生的。欲知更多雅思资讯，请大在线咨询上海环球青藤网，或者是拨打免费电话400-820-0602进行咨询。
