Question

    Peter Skyllberg, a Swedish man, was trapped in his car for two months, with temperatures reaching -30^oC, with no food or water, and yet he survived. The best explanation was that his vehicle created an “igloo (snow house) effect” and protected him from the extremely low temperatures and that his body would hibernate(冬眠) during this time.

Can humans get into a low-energy consumption state like a bear by reserving energy, and reducing body temperature? Chinese scientists are looking for the key to regulating body temperature.

Scientists have found the hypothalamus (下丘脑), an area in the central lower part of the brain, is responsible for regulating body temperature. Wang Hong, a brain scientist at the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences, led her team to mark the neurons (神经元) responsible for regulating body temperature in mice by means of a cutting-edge genetic biology technique. In the experiments, they injected (注射) drug into mice to make the body temperatures of the mice drop rom 37C to 27 in two hours. The team found the change in body temperature caused no harm to the health of the mice. “We don’t know if we can develop a drug that can control human body temperature. We still need a lot of study.” Wang said.

Chinese scientists are not alone in such research. Body-cooling techniques are being used in pioneering hospitals around the world. Dutch doctors are now using low temperatures for patients who have suffered brain injuries in accidents, According to doctors working in Florence, it may even help to save the brains of babies who are born suffering from severe epileptic fits (癫痫病发作).

1.Why does the author mention Peter Skyllberg?

A. To tell an amazing story.    B. To introduce the topic.

C. To teach survival skills.    D. To explain “igloo effect”.

2.What did Wang Hong’s team find in the experiment?

A. Genetic biology technique helped a lot.

B. A drug could control human body temperature.

C. The mice’s health wasn’t damaged by the change of body temperature.

D. Hypothalamus was responsible for regulating body temperature.

3.How can body-cooling techniques help people?

A. Brain injuries may be treated properly

B. People trapped in snow can survive.

C. Patients with epileptic fits will be cured.

D. Medical accidents can be avoided.

4.The text is probably taken from      .

A. a biology textbook    B. a science fiction

C. a survival brochure    D. a medical magazine

Answer

1. B

2. C

3. A

4. D

【解析】

本文是一篇说明文，介绍了科学家发现体温的变化不会对白鼠的健康造成损害，而且目前降体温疗法已经应用于医学上治疗脑损伤。

1.推理判断题。根据第一段中的“The best explanation was that his vehicle created an “igloo (snow house) effect” and protected him from the extremely low temperatures and that his body would hibernate(冬眠) during this time.”可知， Peter Skyllberg被困在车里两个月，在低温、没有食物和水的情况下奇迹存活的原因是他的车创造了一种雪屋效应并保护他免受极低的温度，文章提到这个例子就是为了引出科学家发现体温的变化不会对健康造成损害以及降体温疗法应用于医学上这一话题，故B项正确。

2.细节理解题。根据第三段中的“The team found the change in body temperature caused no harm to the health of the mice.”可知，王宏的研究小组发现体温的变化不会对白鼠的健康造成损害，故C项正确。

3.细节理解题。根据最后一段中的“Dutch doctors are now using low temperatures for patients who have suffered brain injuries in accidents,”可知，荷兰的科学家正在用降体温疗法治疗在事故中脑损伤患者，由此可知，降体温技术可以使脑损伤得到适当地治疗，故A项正确。

4.文章出处题。通读全文可知，本文主要介绍了科学家发现体温的变化不会对白鼠的健康造成损害，而且目前降体温疗法已经应用于医学上治疗脑损伤，属于医学范畴，最有可能出自医学杂志，故D项正确。
