Question

【題目】Go “back” in time

Is there a way to quickly recall（回憶）information just before taking an exam? Walking backwards might be a solution. 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, the volunteers were split（分成） into three groups. One group was told to walk 10 meters forward. The second group walked 10 meters backwards. 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 than the other two groups.

This suggests that the link between the concepts（概念）of time and space is important in terms of how our minds form memories. “Time is really expressed via（通過）space,” Aleksandra, who led the study, told the Daily Mail. When you walk backwards, you see things from a different angle（角度） compared to walking forward, This difference helps people recall things that happened in the past.

And walking backwards is not just good for our brains. It is also good for the rest of our body. Compared to walking forward, walking backwards is more challenging. This can help us improve our fitness, according to New Scientist. Walking backwards uses more energy in a short time and burns more calories（卡路里）.

In addition, walking backwards is less stressful for our knees. It could be helpful for people who often have pain in their knees, according to researchers from the University of Oregon in the US. Walking backwards also keeps our spines（脊柱） strong, which can help to ease（緩解）pain in the lower back. This might be why many old people like walking backwards.

【1】What does “this activity” in Paragraph 1 refer to（指的是）?

A. Recalling information.B. Taking an exam.

C. Walking backwards.D. Improving memory.

【2】The second paragraph is written to .

A. introduce a useful way of walking

D. describe how researchers did their experiment

【3】Which group got two more answers correct in the study?

A. The forward-walking group.B. The backward-walking group.

C. The standing-in-one-place group.D. All groups.

【4】According to New Scientist, how can walking backwards be helpful?

A. It helps people remember information.

B. It allows people to see things in a new angle.

C. It helps people burn more calories.

D. It can ease pain in people’s knees and backs.

【5】What do we know from the passage?

A. Walking backwards can help people in many ways.

B. Scientists suggest walking backwards for 10 meters every day.

C. Memories are formed when we do challenging activities.

D. Old people like walking backwards because it can help them lose weight.

文章主要介紹了“向后走”這種運動的好處及研究發(fā)現(xiàn)等。

【1】細節(jié)理解題，“Scientists from the University of Roehampton in the UK said this activity can help people improve their short-term memory. 英國羅漢普頓大學(xué)的科學(xué)家表示，這項活動可以幫助人們改善短期記憶�！�，根據(jù)“Is there a way to quickly recall（回憶）information just before taking an exam? Walking backwards might be a solution.有沒有辦法在考試前快速回憶信息？倒著走可能是個解決辦法”，可知這里的這項活動是指“Walking backwards倒著走”，故選：C。

【2】段意理解題，根據(jù)“Researchers asked 114 volunteers to watch a video. After watching the video, the volunteers were split（分成） into three groups. One group ….. The second group ….. The third ……. All three groups were then asked 20 questions about what they saw in the video.研究人員要求114名志愿者觀看一段視頻。觀看完視頻后，志愿者被分成三組。其中一組被告知向前走10米。第二組向后走了10米。第三組站在一個地方。然后，所有三個組都被問了20個關(guān)于他們在視頻中看到的問題。”可知，這里是講研究人員怎樣研究的，故選：D。

【3】細節(jié)理解題，根據(jù)：“The scientists found that the backward-walking group got two more answers correct than the other two groups.科學(xué)家們發(fā)現(xiàn)，向后行走的一組比另外兩組多得到兩個正確的答案�！庇^察：B。

【4】細節(jié)理解題，根據(jù)： “This can help us improve our fitness, according to New Scientist. Walking backwards uses more energy in a short time and burns more calories（卡路里）”新科學(xué)家的說法，這可以幫助我們提高體質(zhì)。向后走會在短時間內(nèi)消耗更多的能量，消耗更多的卡路里。故選：C。

【5】細節(jié)理解題，根據(jù)“In addition, walking backwards is less stressful for our knees. It could be helpful for people who often have pain in their knees according to researchers from the University of Oregon in the US. Walking backwards also keeps our spines（脊柱） strong, which can help to ease（緩解）pain in the lower back.此外，向后行走對我們的膝蓋來說壓力更小。美國俄勒岡大學(xué)的研究人員表示，對于經(jīng)常膝蓋疼痛的人來說，這可能是有幫助的。向后行走也能使我們的脊椎保持強壯，這有助于緩解背部下方的疼痛�！�，故選：A
