Humans and many other mammals have unusually efficient internal temperature regulating systems that automatically maintain stable core body temperature(核心体温) in cold winters and warm summers.In addition，people have developed cultural patterns and technologies that help them adjust to extremes of temperature and humidity(湿度)．

In very cold climates，there is a constant danger of developing hypothermia(低体温)，which is a life threatening drop in core body temperature to below normal levels.The normal temperature for humans is about 37.0°C.However，differences in persons and even the t ime of day can cause it to be as much as 6°C higher or lower in healthy individuals.It is also normal for core body temperature to be lower in elderly people.Hypothermia begins to occur when the core body temperature drops to 34.4°C.Below 29.4°C，the body cools more rapidly because its natural temperature regulating system usually fails.The rapid decline in core body temperature is likely to result in death.However，there have been rare cases in which people have been saved after their temperatures had dropped to 13.9－15.6°C.This happened in 1999 to a Swedish woman who was trapped under an ice sheet in freezing water for 80 minutes.She was found unconscious，not breathing，and her heart had stopped beating，yet she was eventually saved despite the fact that her temperature had dropped to 13.7°C.

In extremely hot climates or as a result of uncontrollable infections，core body temperature can rise to equally dangerous levels.This is hypothermia.Life threatening hypothermia typically starts in humans when their temperatures rise to 40.6－41.7°C.Only a few days at this extraordinarily high temperature level is likely to result in the worsening of internal organs and death.

本文是一篇说明文。主要介绍了人类及其他哺乳动物具有非同寻常的有效的内部体温调节系统，可以在寒冷的冬天或炎热的夏天自动维持稳定的核心体温。

1．Why can humans keep stable body temperatures in different seasons?

A. Because their bodies are unusually efficient.

B．Because they experience different climates.

C．Because they can adjust to cultural patterns and technologies.

D．Because they have internal temperature regulating systems.

D[细节理解题。根据第一段第一句可知，在不同季节人类能够保持稳定的核心体温是因为他们具有有效的内部体温调节系统。故选D。]

2．What does Paragraph 2 mainly discuss?

A. The dangerous effects of hypothermia.

B．The change of body temperature.

C．The survival of the Swedish woman.

D．The regulating systems of natural temperature.

A[段落大意题。根据第二段第一句可知，第二段主要讲述了低体温会造成的危害。故选A。]

3.People are unlikely to survive under the body temperature ________．

A．higher than 34.4°C

B．lower than 29.4°C

C．between 40.6－41.7°C

D．between 34.4－37°C

B[推理判断题。根据第二段中的“Below 29.4℃，the body cools more rapidly because its natural temperature regulating system usually fails.The rapid decline in core body temperature is likely to result in death.”可推知，低于29.4°C时，人体不能保持核心体温，因此无法生存。故选B。]

4．What is the best title for the passage?

A．Surviving in an ice trap

B．Getting to know hypothermia

C．Adapting to climate extremes

D．Changing core body temperature

C[标题归纳题。根据第一段中的“help them adjust to extremes of temperatur e and humidity(温度)”以及文章整体内容可知，本文主要讲述了人类通过内部核心体温以及发展文化模式和技术来适应气候的变化。故C项“适应极端气候”概括了文章大意，适合做文章标题。故选C。]

Glad to be grey

The recession(经济衰退)of 2008－09 was remarkable in rich countries for its intensity，the subsequent recovery for its weakness.The labour market has also broken the rules，as new research from the OECD，shows in its annual Employment Outlook.

Young people always suffer in recessions.Employers stop hiring them；and they
