男，42岁。拟诊为粘连性肠梗阻，住院观察治疗期间，出现持续性腹痛，阵发性加剧。查体：腹肌紧张，全腹压痛、反跳痛，肠鸣音消失。下列措施最适当的是（）

三、阅读下面文字，完成下面4个小题。

　　下列植物生理的理论研究成果，是生物化学调控技术的依据。

　　植物根茎叶的表面可以吸收具有生理活性的有机物质。这些物质一进入植物体内，就可随维管束的筛管液流与导筛水流传布周身。植物的这种特性给农用药剂大开方便之门。原来需要从根系吸收的矿质元素中，有些元素易被土壤固定，因而不容易被植物吸收利用，若采用溶液喷射的根外追肥，就能解决这个问题。此外，农用药剂可以“内服”――注射法，并能在体内转移与保留。一向“外敷”用作保护层的除害药剂，只能对覆盖的枝条有效，用量大、期限短，二者比较起来，已不可同日而语。

　　溶液培养植物成功，确定了营养代谢所需的水分与必需的矿质元素的性质和数量，成为合理、定量灌溉与施肥的依据，并给无土栽培作出了榜样。自然资源在太阳的操纵下，不仅供给植物生活的能量，还给植物个体发育提供必需的生态环境。再通过植物体内部的相互影响，植物的遗传性状才能实现。植物为了维持生存，依靠感应性来适应气候中光、温和季节周期的变化，以及逆境的胁迫。植物常在敏感部位受到刺激后，便发出信使在体内传递，影响效应部位反应出来。研究发现，这些信息是激素一类的生物化学物质，它们的生理活性强、功能各异，化学结合比较简单，可以人工模拟与批量合成。无论是内原激素，还是人工调节剂，在植物上微量施用，就会启发显著的生理变化。

“就会启发显著的生理变化”，“生理变化”指的是（）

A．植物体内部的相互影响以实现遗传性状

B．植物为了生存，适应环境的变化与胁迫

C．植物的敏感部位发出的信息在体内传递

D．植物的某些部位接受刺激发生的反应效应

阅读理解。

     One of today's hottest topics among women (and to an extent among men too now) is anti

aging and how to reverse the signs of age. The beauty industry has responded to this by offering

a wide collection of anti aging creams and other anti aging products aimed at all pocketbooks,

ranging from economical to highly priced.

     And the question is "do any of these often much-vaunted (被过度吹嘘的) anti aging creams

actually work?" And if they do,how precisely do they perform their miracles?

Well the appropriate response to that is that they do work - after a fashion. There certainly are

anti aging creams available for a relatively modest price that will reduce the appearance of wrinkles

in a comparatively short period of regular application. But this really is the limit of their powers:

they won't actually undo skin damage or eradicate (根除) all signs of age；they will simply modify

them,some more effectively than others.

     The way they work is like so: they remove upper layers of dead skin cells and make deeper

layers absorb water,serving to plump them up and make them look fuller and healthier. But since

such anti aging creams only go skin deep,as it were,skin damage will reappear once you stop using

the anti aging wrinkle cream.

This means fairly heavy regular use,which might be costly depending on your choice of product.

However,if you can afford it or think it's worth the cost,it won't be such an issue. After all,what

woman wants to look older than her years when looking good is so tied up with many women's

self-esteem and sense of identity.

     A compromise (折中) solution for those on a tighter budget is to use the cheaper creams. In

addition,it's always wise to be a little experimental to make sure you end up with the one that suits

our skin best.

     So,to sum up: an anti wrinkle face cream will work within limits,depending on your objective.
