Question

【題目】Airbags, now found in almost every vehicle, have saved countless lives and largely reduced the severity of injuries in crashes. Similar technology could greatly reduce broken hips (髖部) resulting from a fall, something most seniors fear.

Dr. Robert Buckman and his start-up company, Active Protective in Allentown, Pennsylvania, has developed a promising solution, a wearable airbag that can protect hip bones in the event of a fall. The idea was the result of Dr. Buckman’s years as a doctor at Temple University. He noticed how many elderly people were being brought into hospitals with broken hip due to falls, and how they often never completely recovered from the injuries. He started to ask what he could do for these people, and that was when he started trying to figure out whether there was a way of helping people who were at the highest risk of falling and suffering these kinds of injuries.

The device is worn much like a regular belt, but on the outside of the clothing, and it includes sensors that monitor the movement of hips. If the device detects that the person, is falling, an airbag opens before the person hits the ground, cushioning the fall. When the wearer hits the ground, the bag reduces the force to the hip bones by 90 percent, enough to avoid the majority of hip injuries.

With one out of every three people aged 65 and older suffering serious falls each year, Active Protective has a big market for its wearable device. It also has the potential to sizably reduce hip - related health care expenses: Hip injuries among the elderly cost the US health care system in 2012 $30 billion, which doesn’t include the long-term care expenses associated with the high percentage of patients that can no longer live independently.

【1】What is the purpose of the Active Protective’s airbag?

A. To avoid hip injuries among seniors.

B. To protect seniors from car accidents.

C. To help seniors with their daily nursing.

D. To help doctors deal with serious injuries.

【2】What inspired Dr. Robert Buckman to make the device?

A. A report on seniors’ health.

B. A serious fall he experienced.

C. His work experiences as a doctor.

D. Suggestions of seniors at Temple University.

【3】How does the device mainly work?

A. By predicting road conditions. B. By speeding up bone recovery.

C. By reducing the effects of falling. D. By preventing people from failing.

【4】What does the author think of the Active Protective’s airbag?

A. It still needs improving.

B. It has a promising future.

C. It may encourage seniors to do exercise.

D. It may increase America’s spend on seniors.

【2】C

【3】C

【4】B

【解析】

本文屬于說(shuō)明文。講述一個(gè)從醫(yī)多年的醫(yī)生為了緩解老人跌倒的問(wèn)題，專(zhuān)門(mén)研發(fā)了一款可穿戴的氣囊。該氣囊內(nèi)置監(jiān)測(cè)器，當(dāng)檢測(cè)到老人跌倒時(shí)，氣囊會(huì)自動(dòng)打開(kāi)，避免老人髖骨受傷。

【1】推理判斷題。根據(jù)第二段Dr. Robert Buckman and his start-up company, Active Protective in Allentown, Pennsylvania, has developed a promising solution, a wearable airbag that can protect hip bones in the event of a fall.可知，該公司研發(fā)了一款可穿戴的氣囊，為了在老人跌倒時(shí)保護(hù)老人的髖骨，故選A。

【2】細(xì)節(jié)理解題。根據(jù)第二段The idea was the result of Dr. Buckman’s years as a doctor at Temple University.可知，該醫(yī)生研發(fā)氣囊是源于自己多年從醫(yī)經(jīng)歷所發(fā)現(xiàn)的情況，故選C。

【3】細(xì)節(jié)理解題。根據(jù)第三段When the wearer hits the ground, the bag reduces the force to the hip bones by 90 percent, enough to avoid the majority of hip injuries.可知，當(dāng)穿戴者著地時(shí)，氣囊會(huì)減少地面對(duì)髖骨90%的沖擊，讓老人少受傷害，故選C。

【4】推理判斷題。根據(jù)最后一段With one out of every three people aged 65 and older suffering serious falls each year, Active Protective has a big market for its wearable device.可知，老人跌倒受傷情況很普遍，因而這個(gè)氣囊很有市場(chǎng)，故選B。
