Question

【題目】 Is there a way to quickly remember information just before taking an exam? Walking backwards might be a way to solve this problem. Scientists from the University of Roehampton in the UK said this activity can help people improve their short-term memory.

Researchers asked 114 volunteers to watch a video. After watching the video, volunteers were divided into three groups. One group was told to walk 10 metres forward. The second group walked 10 metres backward. The third group stood in one place. All three groups were then asked 20 questions about what they saw in the video.

The scientists found that the backward- walking group got two more.answers correct on average than the other groups.

This suggests that the relationship between the concepts(概念）of time and space is important considering how our minds form memories. "Time is really expressed via(通過）space,”Aleksandar Aksentijevic, who led the study, told The Daily Mail. When you walk backward, you see things from a different way compared to walking forward. This difference helps people recall things that happened in the past.

And walking backward is not just good for our brains. It is also good for the rest of our body. Compared to walking forward, walking backward is more challenging. This can ameliorate our health, according to New Scientist, Walking backward uses more energy in a short time and burns more calories.

Besides, walking backward is less stressful for our knees. It could.be helpful for people who often have pain in their knees, according to researchers from the Unegon in the US. Walking backward also keeps our spines（脊柱）strong, which can help to reduce pain in the lower back. This might be why many old people like walking backward.

A. harmB. improveC. controlD. spread

【4】According to New Scientist,why is walking backward helpful?

A. It helps people remember information

B. It helps people burn more calories.

C. It reduces pain in people's knees and backs.

D. It allows people to solve problems in different ways

【5】What is the best title for this passage?

A. Let's exercise our brainB. Let's do an experiment

C. Let's walk backwardD. Let's do more exercise

Answer 1

【答案】

【1】A

【2】D

【3】B

【4】B

【5】C

【解析】

短文大意：短文通過實驗對比，發(fā)現(xiàn)倒著走路能提高短時記憶，具有在短時間內(nèi)消耗更多的能量，燃燒更多的卡路里，有助于減少腰背部的疼痛等諸多好處，建議人們通過倒著走進行鍛煉。

【1】題意：在實驗中，第一組被要求向前走10米�？疾榧毠�(jié)理解。根據(jù)One group was told to walk 10 metres forward.，可知第一組被要求向前走10米，故選A。

【2】題意：實驗表明，倒著走路能提高短時記憶�？疾榧毠�(jié)理解。根據(jù)開頭Walking backwards might be a way to solve this problem. Scientists from the University of Roehampton in the UK said this activity can help people improve their short-term memory.（倒著走路這種活動可以幫助人們改善短期記憶），結(jié)合實驗結(jié)果The scientists found that the backward- walking group got two more answers correct on average than the other groups.（后向行走組比其他組平均多答對兩個問題），可知倒著走路能提高人的短時記憶，故選D。

【3】題意：文中劃線的單詞“ameliorate”的意思是“_______________”�？疾樵~義理解。根據(jù)下文according to New Scientist, Walking backward uses more energy in a short time and burns more calories. （倒著走路在短時間內(nèi)消耗更多的能量，燃燒更多的卡路里），可知倒著走路能改善我們的健康，improve改善，故選B。

【4】題意：據(jù)《新科學(xué)家》雜志報道，為什么倒著走路有幫助?考查細節(jié)理解。根據(jù)according to New Scientist, Walking backward uses more energy in a short time and burns more calories.（根據(jù)《新科學(xué)家》的研究，倒著走路在短時間內(nèi)消耗更多的能量，燃燒更多的卡路里），可知It helps people burn more calories.（它幫助人們?nèi)紵�更多的卡路里）說法正確，故選B。

【5】題意：這篇文章最好的題目是什么?考查標(biāo)題歸納。A. Let's exercise our brain讓我們鍛煉大腦；B. Let's do an experiment讓我們做個實驗；C. Let's walk backward 讓我們倒著走；D. Let's do more exercise讓我們多做運動。根據(jù)Walking backwards might be a way to solve this problem. …this activity can help people improve their short-term memory.，結(jié)合文中的實驗對比，可知介紹的是倒著走的好處，故選C。
