Question

【題目】Choose the best words or expressions and complete the passage

Number sense is not the ability to count. It is the ability to recognize a change in number. Human beings are born with this ability. ______________, experiments show that many animals are, too. For example, many birds have good number sense. If a nest (巢) has four eggs and you remove one, the bird will notice. However, if you remove two, the bird generally leaves. This means that the bird ______________the difference between two and three.

Another interesting experiment showed a bird's______________number sense. A man was trying to take a photo of a crow (烏鴉) that had a nest in a tower, but the crow always left when she saw him coming. The bird did not______________ until the man left the tower. The man had an idea. He took another man with him to the tower. One man left and the other stayed, but they weren't successful in fooling the bird. The crow stayed away until the second man left, too. The experiment was_______________with three men and then with four men. It was not until five men went into the tower and only four left that they finally managed to take a photo.

How good is a human's number sense? It's not very good. For example, babies about fourteen months old______________ notice if something is taken away from a small group. But when the number goes beyond three or four, the children are often very confused.

It seems that number sense is something we have in common with many animals in this world, and that our human ability is not much better than a crow's.

文章大意：本文是一篇說事理性的說明文，篇章模式為總-分-分-總的結(jié)構(gòu)。第一段提出話題，說明什么是數(shù)字感，并通過拿鳥類作為例子說明，不僅人類與生俱來都有這種數(shù)字感，而且動物也有；第二段運用一個人想對一只烏鴉進行拍照的另一個有趣的例子來進一步鳥類的神奇的數(shù)字的分辨力；第三段，以一個嬰兒為例說明人類的數(shù)字感并不是很好；最后一段為結(jié)論段，重申主題：人類和許多動物一樣都有數(shù)字感，而且人類的這種能力不比烏鴉好多少。

【1】句意：令人驚訝地是，實驗表明許多動物也是。

考查副詞。Importantly重要的是；Surprisingly出人意料地；Disappointedly失望地；Fortunately幸運地。根據(jù)上下文句意，由“Human beings are born with this ability...”到“experiments show that many animals are, too...”可看出空格前后句意上表達出遞進關(guān)系。應填Surprisingly。故選B。

【2】句意：這意味著這只鳥發(fā)現(xiàn)了二和三的區(qū)別。

考查動詞短語。went out出去；found out發(fā)現(xiàn)；looked out注意；turned out關(guān)掉，熄滅（電燈、煤氣等）。概括結(jié)論性，根據(jù)上文的事例，“If a nest has four eggs and you remove one, the bird will notice...”得出結(jié)論。帶入選項B“found out”句意為“鳥類能發(fā)現(xiàn)兩個和三個之間的區(qū)別”。符合句意。應填found out，故選B。

【3】句意：另一個有趣的實驗顯示了鳥類驚人的數(shù)字感。

考查形容詞。forgetful健忘的；friendly友好的；amazing 驚人的；silly愚蠢的。根據(jù)下文實驗事例，“It was not until five men went into the tower and only four left that they finally managed to take a photo...”推測結(jié)論為“驚人的數(shù)字意識”更符合句意。應填amazing，故選C。

【4】句意：那只鳥直到那人離開塔樓才回來。

考查動詞。escape逃跑；return返回；fly飛； sing唱。根據(jù)上下文句意，由“The bird did not...until the man left the tower...”得出，return帶入更符合句意。故選B。

【5】句意：實驗由三個人重復，然后由四個人重復。

考查動詞。Noticed注意；mentioned提到，提及；repeated重復；produced 產(chǎn)生。根據(jù)上下文句意，“The experiment was…with three men and then with four men. It was not until five men went into the tower and only four left that they finally managed to take a photo.”可見該實驗進行反復檢測調(diào)整，故填“repeated”，故選C。

【6】句意：例如，14個月大的嬰兒很少注意到是否有東西從一個小群體中被拿走。

考查副詞。never從不；rarely很少, 不常；properly正確地，恰當?shù)兀?/span>usually通常地。首尾呼應。根據(jù)上文，“How good is a human's number sense? It's not very good...”得知人類對數(shù)字的意識不是很好，又由“...But when the number goes beyond three or four, the children are often very confused...”得出“rarely”“很少發(fā)現(xiàn)”更符合句意。故選B。

完型填空，考查學生們在具體語境中運用語言的能力，綜合性較強。做題時，應先通讀短文，了解大意；然后根據(jù)上下文語境的提示做題，先易后難，注意辨析選項中的單詞的意思和用法，并注意空前后的搭配；最后應再讀一遍短文，檢查答案。例如第1小題，句意：令人驚訝地是，實驗表明許多動物也是�？疾楦痹~。Importantly重要的是Surprisingly出人意料地；Disappointedly失望地；Fortunately幸運地。根據(jù)上下文句意，由“Human beings are born with this ability...”到“experiments show that many animals are, too...”可看出空格前后句意上表達出遞進關(guān)系。應填Surprisingly。故選B。
