Question

【題目】 For a long time, scientists believed that only humans were left-or right-handed. However, recent studies have shown that this isn’t true. Just like people, animals favor one side or the other.

In Ireland, scientists studied a group of 42 cats. They gave them three tasks. One was to get a delicious piece of fish out of a bottle. They found that the male cats preferred to use their left paw, and the female cats preferred to use their rights.

Being left-or right-handed isn't limited (有限的) to arms and legs. It can include eyes, ears, claws, and even tails. In Italy, scientists discovered that dogs wag their tails to the right when they see something that they like. When they see something that they don’t like, their tails go to the left.

There are lots of fun examples. Left-handed dolphins swim in a different direction around the pool. Elephants like to swing their trunks in one direction. Even snakes prefer to curl up only one way.

Many people believe that polar bears are left-handed. They say, for example, that polar bears cover their black nose with their right paw, which helps them hide in the snow when they are hunting. Then they can sneak up(慢慢靠近) on a seal, and their left paw will be free to catch it.

Scientists, however, disagree. Some have watched polar bears for thousands of hours. They never saw the bears cover their nose during a hunt. They also saw no evidence(根據(jù)) that they were left-handed. Without taking any notice of this, many websites continue to say that polar bears are left-handed.

Scientists are still learning about animals and their behaviors. The next time you see an animal, whether it’s your pet cat or an elephant, try figuring out yourself which it prefers - left or right.

【解析】

本篇文章難度適中，主要講述不但人有左撇子和右撇子，動(dòng)物也有左撇子和右撇子。并列舉了貓、海豚、狗以及北極熊等例子。

【1】詞義猜測(cè)題。根據(jù)For a long time, scientists believed that only humans were left-or right-handed. However, recent studies have shown that this isn’t true. Just like people, animals favor one side or the other“很長一段時(shí)間以來，科學(xué)家們認(rèn)為只有人類是左撇子或右撇子。然而，最近的研究表明這不是真的。就像人一樣，動(dòng)物也有偏愛的一面”可知，動(dòng)物也有喜歡的一面，故選D。

【2】主旨大意題。根據(jù)In Ireland, scientists studied a group of 42 cats. They gave them three tasks. One was to get a delicious piece of fish out of a bottle. They found that the male cats preferred to use their left paw, and the female cats preferred to use their rights“在愛爾蘭，科學(xué)家們研究了一組42只貓。他們給了他們?nèi)齻�(gè)任務(wù)。一種是從瓶子里拿出一塊美味的魚。他們發(fā)現(xiàn)，雄貓更喜歡使用它們的左爪，而雌貓更喜歡使用它們的右爪”可知，主要講述一項(xiàng)關(guān)于貓的研究以及研究的發(fā)現(xiàn)，故選B。

【3】細(xì)節(jié)理解題。根據(jù)They say, for example, that polar bears cover their black nose with their right paw“例如他們說北極熊用他們的右爪蓋住他們的黑鼻子”可知，不使用左手遮住他們的黑鼻子，排除A；根據(jù)They never saw the bears cover their nose during a hunt“在打獵期間，他們從未看見看見熊遮住他們的鼻子”可知，科學(xué)家不支持“當(dāng)他們打獵時(shí)，他們會(huì)蓋住鼻子”這一觀點(diǎn)，排除B；根據(jù)They also saw no evidence(根據(jù)) that they were left-handed. Without taking any notice of this, many websites continue to say that polar bears are left-handed“他們也沒有發(fā)現(xiàn)他們是左撇子的證據(jù)。許多網(wǎng)站沒有注意到這一點(diǎn)，繼續(xù)說北極熊是左撇子”可知，許多網(wǎng)上有關(guān)北極熊是左撇子的信息是不可信的，排除D；根據(jù)Many people believe that polar bears are left-handed“許多人相信北極熊是左撇子”以及Scientists, however, disagree“然而，科學(xué)家不同意”可知，科學(xué)家們不同意北極熊是左撇子的普遍看法。故選C。

【4】推理判斷題。根據(jù)For a long time, scientists believed that only humans were left-or right-handed. However, recent studies have shown that this isn’t true. Just like people, animals favor one side or the other“很長一段時(shí)間以來，科學(xué)家們認(rèn)為只有人類是左撇子或右撇子。然而，最近的研究表明這不是真的。就像人一樣，動(dòng)物也有偏愛的一面”以及Scientists are still learning about animals and their behaviors. The next time you see an animal, whether it’s your pet cat or an elephant, try figuring out yourself which it prefers - left or right“科學(xué)家們?nèi)栽谘芯縿?dòng)物及其行為。下次你看到動(dòng)物的時(shí)候，不管是你的寵物貓還是大象，試著自己找出它更喜歡哪一個(gè)——左邊還是右邊”可知，本篇文章的目的是介紹動(dòng)物最新的研究，故選A。
