混凝土是现代建筑的最主要材料之一,它在青藏铁路工程中尤为重要。青藏铁路桩基使用的水泥都是特殊配方的。以适应当地严酷的自然环境。浇铸桩基最主要的因素是湿混凝土的温度。将湿混凝土的温度降至零上5度,混凝土就会很快地与周围冻土冻结在一起。即使冻土的上层在夏天发生融沉。深入地下的桩基部分依然坚固,承载力不变。在永久冻土区修铁路时。温度可能是你最危险的敌人,也可能是你最好的朋友。对上述文字概括最恰当的一项是()。

A. 混凝土这一现代建筑材料在青藏铁路建设中发挥了汗马功劳
B. 在浇铸桩基过程中控制湿混凝土的温度解决了青藏铁路在永久冻土区的修建难题
C. 修建青藏铁路的核心问题是如何将混凝土桩基打人极不稳定的冻土,并且避免冻土融化
D. 在永久冻土区修铁路,温度是把“双刃剑”

第一篇
It is my privilege to introduce again an annual report of the work of Our Lady's Hospice.
Our Lady's Hospice, the first of its kind in these western islands, has centered the second century of caring for those with terminal illness. It was first opened in Milltown and its opening was the realization of a long cherished(心中怀着)dream. For years the Sisters(修女)had longed for a place where poor, lonely, friendless dying persons--no longer fit subjects for hospital wards(病房)--could find care, comfort and peacefulness in their last days of life. In December 1879 these hopes were fulfilled when Our Lady's formally welcomed the first patients--35 in number.
So great were the applications for admission that six years later the foundation stone of the present Hospice was laid on 18th July 1886 and completed in August 1888.
Much has been written about the spirit of the Hospice and much will continue to be written with present increasing interest in the Hospice was opened in a spirit that regarded neither race, nor belief, nor class but looked simply to the need of the person for help and for peace in the last days of life. We hope the same spirit born out of love, care and respect for the dignity and worth of each human person, will comfort all, both patients and their loved ones, who seek our help in the Hospice today.
This report is given by ______.

A. a reporter who is interested in Hospice work
B. a patient representative
C. a leading figure of the Hospice
D. one of the founders of the Hospice
