某城市道路改造工程,随路施工的综合管线有0.4MPa的DN500中压燃气、DN1000给水管并排铺设在道路下,燃气管道与给水管材均为钢管,实施双管合槽施工。热力隧道工程采用暗挖工艺施工。承包方A公司将工程的其中一段热力隧道工程分包给B公司,并签了分包合同。
1.B公司发现土层松散,有不稳定迹象,但认为根据已有经验和这个土层的段落较短,出于省事、省钱的动机,不仅没有进行超前注浆加固等加固措施,反而加大了开挖的循环进尺,试图“速战速决,冲过去”,丝毫未理睬承包方A公司派驻B方现场监督检查人员的劝阻。结果发生隧道塌方事故,造成了3人死亡。
2.事故调查组在核查月公司施工资格和安全生产保证体系时发现,B公司根本不具备安全施工条件。
问题

试述燃气管道强度试验和严密性试验的压力、稳定时间及合格标准。

     What is your favorite color? Do you like yellow, orange, red? If you do, you must be an optimist, a leader,

an active person who enjoys life, people and excitement. Do you prefer grey and blues? Then you are probably

quiet,shy and you would rather follow than lead. If you love green, you are strong-minded and determined. You

wish to succeed and want other people to see you are successful. At least this is what psychologists (心理学

家) tell us, and they should know, because they have been seriously studying the meaning of color preference,

and the effect that colors have on human beings. They tell us that we don't choose our favorite color as we

grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you

could see clearly.

     A yellow room makes us feel more cheerful and more comfortable than a dark green one, and a red dress

rings warmth and cheer to the saddest winter day. On the other hand,black is depressing (压抑). Light and

bright colors make people not only happier but more active. It is a fact that factory workers work better, harder,

and have fewer accidents when their machines are painted orange rather than black or dark gray.

     Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a

few colorful things. Remember also that you will know your friends and your enemies better when you find

out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when

you choose a piece of handkerchief.

1. According to this passage, _____.

A. one can choose his color preference

A. colors do have effect on our moods (情绪)

C. psychologists have been studying the meaning of color preference
