题目:

【背景资料】某高层商业建筑位于闹市区,同边建筑物较多,地质条件复杂,地下水位较高;设计采用两种桩基础:泥浆护壁成孔灌注桩(8O根,桩径1.2米,水下C30混凝土,均为端承桩),预应力混凝土管桩(234根,桩径0.4米,均为摩擦桩)。

情形1:A区管桩群北边临近有一危房,施工过程发现其中一根桩沉桩困难,压载力达到设计要求,桩顶标高未达到,质量员取得现场监理认可后同意验收。

情形2:灌注桩施工时,技术交底要求严格按设计桩顶标高控制桩顶浇筑标高,混凝土坍落度控制在80-120mm,桩身垂直度控制在1%以内,在砂性土中清孔后泥浆比重控制在1.2左右,沉渣厚度不超过50mm。

情形3:某根灌注桩长27米,钢筋笼分段加工吊放,受力钢筋(φ25)搭接连接采用双面电弧焊,钢筋笼内侧对称安装超声波检测管。

情形4:有5根桩的混凝土标准养护试块强度不合格,经对桩体钻芯取样检测,桩体混凝土实际强度均满足要求。 请根据背景资料完成以下选项

对地质条件复杂、成桩质量可靠性低的灌注桩应采用()试验方法进行承载力检测。

A、动力参数法

B、静荷载

C、小应变法

D、抽芯法

One day in my class,Maria shared her feelings about money,“Money worries me.I think I want to live without money because I hate it.I HATE MONEY.”We were all touched by Maria's words as they reminded us of the spiritual burdens that money managing can bring to us.After class I offered to help Maria deal with her financial problems.She hesitated to accept my offer,and I could see from the expression on her face that she was afraid of what it might involve.I quickly promised her that I wouldn't make her do more than she was able to.I told her frankly that I didn't enjoy managing my money any more than she did hers and wouldn't burden her with guilt,judgments,or impossible tasks.All I would ask her to do was to let me help her look at her fears and try to make some sense of them.

Maria still resisted my offer,and I can remember the excuses she gave me as they were the repeated complaints I had heard from so many people.“I'll never understand money,”she said.“My facts are meaningless.”“I don't deserve to have money.”“I never have enough.”“I have too little to manage.”“My financial position isn't worth looking at.”and the most devastating one of all,“I just can't do it.”

Going home that day,I couldn't get Maria out of my mind:her attitude conveyed the same negativity and  fear that I believed annoyed many people.I was sure it was this attitude that prevented people from managing their money effectively.My counseling(咨询)has taught me that these anxieties are inseparably connected to our self­doubts and fear for survival.Many of us are terrified of handling our money because we don't believe we can do it well,and to do it wrong would put our very existence at risk.

On a deeper level we know that money is not the source of life,but sense of worth drives us to act as if it were.It locks us up in self­doubts and prevents us from tapping into the true source of our management power,our spirit.

小题1:The underlined word“devastating”in Paragraph 2 probably means ________.

A.convincing

D.valuable小题2:Maria's words moved the author and others because they were ________.

A.in the same financial trouble

A.overcome her fears

B.make wise decisions

C.avoid making mistakes

D.learn the necessary skills小题4:Maria wouldn't take the author's offer of help for fear of________.

A.being forced to share her money with others

B.having to do something beyond her reach

C.being found guilty of making impossible errors

D.showing her judgment about money小题5:According to the author,people's anxieties about managing money result from their understanding of money as the only source of ________.

When the system upon which a transport entity is running fails and subsequently restarts,the(21) information of all active connections is lost. The affected connections become half-open, as the side that did not fail does not yet realize the problem.The still active side of a half-open connections can close the connection using a(22)timer. This timer measures the time the transport machine will continue to await an (23) of a transmitted segment after the segment has been retransmitted the maximum number of times.When the timer (24),the transport entity assumes that either the other transport entity or the intervening network has failed. As a result, the timer closes the connection, and signals an abnormal close to the TS user. In the event that a transport entity fails and quickly restarts, half-open connections can be terminated more quickly by the use of the RST segment, the failed side returns an RST i to every segment i that it receives. When the RST i reaches the other side, it must be checked for validity based on the (25) number i, as the RST could be in response to an old segment. If the reset is valid, the transport entity performs an abnormal termination.

空白处(25)应选择()

A.sequence

B.acknowledgment

C.connection

D.message
