高三试题

阅读材料，完成下列要求。
材料《盛世危言》，是中国近代思想家郑观应的重要著作，于清光绪二十年（1894年）正式出版。《盛世危言》是一个全面系统地学习西方社会的纲领，它不讳言中国在社会生活的许多方面落后于西方。提出了从政治、经济、教育、舆论、司法等诸方面对中国社会进行改造的方案。在政治上不但提出了建立议会式的立宪政体，而且提出了将政治公开于传媒，由朝野各方评论，这样才可能使施政臻于完善；在经济上郑氏主张由民间组建工商业团体，大力发展现代工业；在教育上，从基础教育到高等教育都有新见解；在司法上他指出了中国的法律和法律的运用无不体现了黑暗与残暴，所以须得向西方学习，他说：“西人每论中国用刑残忍，不若外国宽严有制，故不得不舍中而言外，取外而酌中。”光绪二十一年，江苏布政使臣邓华煕曾将《盛世危言》五卷本推荐给光绪，光绪批示印制2000部，分发给各省官员该书印刷达十余万部之多，并成为科举士子的必读参考书籍，它是中国近代出版史上版本最多的书。

Analysis of the composition of quicksand shows that there are four key ingredients—sand, obviously water, clay and salt. Together these materials form a structure resembling a house of cards, with large water-filled gaps between the sand particles, which are loosely glued in place by the clay. As long as it’s left alone, the structure remains stable. But as soon as it’s disturbed, by stepping on it, the clay changes from a jelly-like consistency to a runny liquid. The effect is the same as stirring a pot of yoghurt. Liquefying(溶解)the clay makes the quicksand about one million times runnier, and the whole house of cards comes tumbling down, with you inside it.

Very quickly, the sand sinks to the bottom and the water floats to the top. This is where the salt comes in. When there’s enough salt present, as soon as the clay particles liquefy, electrical charges make them begin to stick together to form bigger particles and these also settle with the sand. Quicksand is a mixture which looks like solid, but behaves more like a liquid.

Despite its murderous reputation, quicksand does not such people under and swallow them, although it can hold a person in firm grip. The human body is more buoyant(有浮力) in quicksand than in water, and sooner or later anyone trapped in it will float.

Unlike most liquids, quicksand’s viscosity, or “runniness” can suddenly change if it comes under pressure, for example under a human foot. The surface gives way and the victim quickly sinks in up to the knees, surrounded by an area of dirty things that turns semi-solid around its victim. Escaping from the quicksand’s grip(紧握) requires a large amount of force. Without something solid to pull at, people often find they are stuck fast. Pulling at one leg simply makes the other one sink further.

So how do you escape from quicksand’s control? Stay still and call for help. Staying still stops you sinking any further, until--with luck--help arrives on the scene. If no one appears and you need to draw yourself out, gently lie down on your back until your body is floating on the sand. Next, roll over onto your stomach and pull yourself forwards with your hands, so that you gradually “swim” towards firmer ground. It is a slow and dirty business, but it works.

This technique has one barrier: it goes against a very powerful human nature. Faced with danger in the open, nine out of ten stay on their feet so that they can run away, in which case it can worsen the situation.

32．Which ingredient of the quicksand make someone trapped in it stuck and stuck fast?

A. Sand B. Clay C. Water D. Salt

33．From the passage we can learn that ________

A. as long as you are strong enough, you can pull yourself up from quicksand on your own

B. clay glues sand particles loosely, which makes quicksand stable, unless it is disturbed

C. because anyone trapped in quicksand will float, there is little possibility of him dying

D. looking like solid ground, quicksand is actually liquid

34．If someone is trapped in quicksand, what should he do?

A. Remain calm and wave for help

B. Stand in quicksand and get ready to run away as quickly as possible

C. “Swimming” is one of the best choices he can use to escape

D. Once in quicksand, lie down on his stomach immediately and swim slowly to safety

35． What might be the best title of the passage?

A. A human killer--quicksand

B. How to escape from danger

C. An awful experience in quicksand

D. What to do if trapped in quicksand

We know that hugs make us feel cosy inside. And this feeling could actually ward off stress and protect the immune (免疫) system, according to a new research from Carnegie Mellon University.

It’s a well-known fact that stress can weaken the immune system. In this study, the researchers sought to determine whether hugs could protect individuals from the increased sensitivity to illness brought on by the particular stress that comes with interpersonal conflict.

“We know that people experiencing ongoing conflicts with others are less able to fight off cold viruses. We also know that people who report having social support are partly protected from the effects of stress on psychological states, such as depression and anxiety, ” the study’s lead author, psychologist Dr. Sheldon Cohen , said in a statement. “We have tested whether awareness of social support is equally effective in protecting us from sensitivity to infection caused by stress and also whether receiving hugs might partially account for those feelings of support and thus protect a person against infection.”

In the experiment, over 400 healthy adults filled out a questionnaire about their perceived (感知到的) social support and also participated in a nightly phone interview for two weeks. They were asked about the frequency that they engaged in interpersonal conflict and received hugs that day.

Then, the researchers exposed the participants to a common cold virus, and monitored them to assess signs of infection. They found that both perceived social support and more frequent hugs reduced the risk of infection associated with experiencing interpersonal conflict. Regardless of whether or not they experienced social conflicts, infected participants with greater perceived social support and more frequent hugs had less severe illness symptoms.

“This suggests that being hugged by a trusted person may act as an effective means of conveying support and that increasing the frequency of hugs might be an effective means of reducing the effects of stress,” Cohen said. “The apparent protective effect of hugs may result from the physical contact itself or hugging being a behavioral indicator of support and closeness. Either way, those who receive more hugs are somewhat more protected from infection.”

If you need any more reason to wrap your arms around someone special, consider this: hugs also lower blood pressure, reduce fears, improve heart health and decrease feelings of loneliness.

A. produce B. increase C. prevent D. support
