Question

【題目】 Everyone knows the strange feeling of your fingers wrinkling up (起皺) when they’re wet. Sometimes when in water, it seems as if your hands have aged 30 years in a second. But is this an accident? Or is it something that nature has built into our bodies?

Scientists at the University of Newcastle in the UK recently did a test. They asked people to pick up things (some wet and some dry). And take them from one place to another. Some people did this with dry hands, while others had to leave their hands in water for 30 minutes first so that their skin was wrinkled. The study found the second group with wet hands had an advantage when carrying things that were also wet.

The scientist Tom Smulders said that “this wrinkling of our fingers in wet conditions could have helped with gathering food from wet vegetation or streams. Wrinkling happens when blood vessels contract (血管收縮) and pull the skin back.

A long time ago, humans lived a very difficult life in a brutal world, where the smallest advantage could make a huge difference. Having wrinkled skin might have helped people catch fish. This would help them get through the winter. These humans would then have had an advantage. Their genes would be accepted by natural selection.

【1】細節(jié)理解題。根據(jù)The study found the second group with wet hands had an advantage when carrying things that were also wet.可知，手濕的人在拿同樣濕的東西時更有優(yōu)勢。因此手濕的人攜帶濕東西很容易故選D。

【2】推理判斷題。根據(jù)The scientist Tom Smulders said that “this wrinkling of our fingers in wet conditions could have helped with gathering food from wet vegetation or streams. Wrinkling happens when blood vessels contract (血管收縮) and pull the skin back.可知，科學家湯姆·斯默德斯說，“在潮濕的條件下，我們手指的這種褶皺可能有助于從潮濕的植被或溪流中收集食物�！币虼�，在潮濕的環(huán)境下，我們的手指起皺有很大的好處，故選C。

【3】推理判斷題。根據(jù)Having wrinkled skin might have helped people catch fish. This would help them get through the winter. These humans would then have had an advantage.可知，很久以前，人類以魚為食，故選B。

【4】詞義猜測題。根據(jù)humans lived a very difficult life可知，人們過著艱難的生活，因此是艱難的世界。故選B。

【5】概括歸納題。根據(jù)“this wrinkling of our fingers in wet conditions could have helped with gathering food from wet vegetation or streams.和Having wrinkled skin might have helped people catch fish. This would help them get through the winter.可知，本文主要談論皮膚起皺的好處，故選A。

認真閱讀題干，根據(jù)題干要求，在文中尋找答案所在的語句或段落，進行分析理解，詞義猜測，推理判斷和概括歸納，選出正確的選項。例如小題3，根據(jù)Having wrinkled skin might have helped people catch fish. This would help them get through the winter. These humans would then have had an advantage.可知，很久以前，人類以魚為食，故選B。
