某水利枢纽工程由电站、溢洪道和土坝组成。土坝的结构形式为均质土坝,上游设干砌石护坡,下游设草皮护坡和堆石排水体,坝顶设碎石路,工程实施过程中发生下述事件:
事件一:项目法人要求该工程质量监督机构对于大坝填筑按《水利水电基本建设工程单元工程质量评定标准》规定的检验数量进行质量检查。工程质量监督机构受项目法人委托,承担了该工程质量检测任务。
事件二:土坝承包人将坝体碾压分包给具有良好碾压设备和经验的乙公司承担。为明确质量责任,单元工程的划分标准是:以50m坝长、30cm铺料厚度为单元工程的计算单位,铺料为一个单元工程,碾压为另一个单元工程。
事件三:该工程监理人给承包人“监理通知”如下:经你单位申请并提出设计变更,我单位复核同意将坝下游排水棱体改为浆砌石,边坡由1:3改为1:2。
事件四:土坝单位工程完工验收结论为:本单位工程划分为20个分部工程,其中质量合格6个,质量优良14个,优良率为70%,主要分部工程(坝顶碎石路)质量优良,且施工中未发生较大质量事故;中间产品质量全部合格,其中混凝土拌合物质量达到优良;原材料质量、金属结构及启闭机制造质量合格;外观质量得分率为82%。所以,本单位工程质量评定为优良。
事件五:该工程项目单元工程质量评定表由监理人填写,土坝单位工程完工验收由承包人主持。工程截流验收由项目法人主持。

It was nearly bedtime and when they awoke next morning land would be in sight. Dr. Macphail lit his pipe and, leaning over the rail, searched the heavens for the South Cross. After two years at the front and a wound that had taken longer to heal than it should, he was glad to settle down quietly at Apia (阿皮亚,西萨摩亚首都) for twelve months at least, and he felt already better for the journey. Since some of the passengers were leaving the ship next day they had had a little dance that evening and in his ears hammered still the harsh notes of the mechanical piano. But the deck was quiet at last. A little way off he saw his wife in a long chair talking with the Davidsons, and he strolled over to her. When he sat down under the light and took his hat you saw that he had very red hair, with a bald patch on the crown, and the red, freckled skin which accompanied red hair, he was a man of forty, thin, with a pinched face, precise and rather pedantic; and he spoke with a Scots acce

[不定项选择题]共用题干
Research shows we make up our minds about people through unspoken communication within seven seconds of meeting them. Consciously or unconsciously,we show our true feelings with our eyes,faces,bodies and attitudes,causing a chain of reactions,ranging from comfort to fear.
Think about some of your most unforgettable meetings:an introduction to your future spouse,a job interview,an encounter with a stranger. Focus on the first seven seconds.What did you feel and think?How did you"read"the other person?How do you think he read you?
You are the message.For 25 years I've worked with thousands who want to be successful.I've helped them make persuasive presentations,answer unfriendly questions,communicate more effectively.The secret has always been you are the message.Others will want to be with you and help you if you use your good qualities.They include:physical appearance,energy,rate of speech, pitch and tone of voice,gestures,expression through the eyes,and the ability to hold the interest of others.Others form an impressiont about you based on these.
Think of times when you know you made a good impression.What made you successful?You were committed to what you were talking about and so absorbed in the moment you lost all self-con-sciousness.
Many books advise you to stride into a room and impress others with your qualities.They instruct you to greet them with"power handshakes"and tell you to fix your eyes on the other person. If you follow all this advice,you'll drive everyone crazy一including yourself.
The trick is to be consistent at your best.The most effective people never change from one situation to another. They're the same whether they're having a conversation,addressing their garden club or being interviewed for a job.They communicate with their whole being;the tones of their voices and their gestures match their words.
The first seven seconds of meeting can help us read the other person.
