Number sense is not the ability to count.

题目内容：

Number sense is not the ability to count. It is the ability to recognize a 1in number. Human beings are born with this ability. 2, experiments show that many animals are, too. For example, many birds have good number sense. If a nest has four eggs and you remove one, the bird will not 3.However, if you remove two, the bird 4leaves. This means that the bird knows the 5between two and three.

Another interesting experiment showed a bird's 6number sense. A man was trying to take a photo of a crow（乌鸦）that had a nest in a tower, but the crow always left when she saw him coming. The bird did not 7until the man left the tower. The man had an 8.He took another man with him to the tower. One man left and the other stayed, but they did not 9the bird. The crow stayed away until the second man left, too. The experiment was 10with three men and then with four men. But the crow did not return to the nest until all the men were 11.It was not until five men went into the tower and only four left that they were 12able to fool the crow.

How good is a human's number sense? It's not very good. For example, babies about fourteen months old almost always notice if something is taken away from a 13group. But when the number goes beyond three or four, the children are 14fooled.

It seems that number sense is something we have in common with many animals in this world, and that our human 15is not much better than a crow's.

答案解析：

小题1:change 考察动词后文中的从four, one, two都说明是在变化。根据上下文意思答题。其他选项A rise 意为上升，B pattern 意为样式， D trend 意为趋向。

小题2:Surprisingly考察副词，根据上下文句意，此处表示惊讶，居然动物也具有这种能力。

小题3:notice 考察动词，原词重现，For example, babies about fourteen months old almost always notice if something is taken away from a 13）意为注意、留意。此题的C hatch选项意为孵化，该词不常见，出处在人教新课标版Book8 U2。

小题4:generally考察副词。根据上下文意思可以得出答案。此句意为“鸟普遍会离开”。另外，此题也可以通过排除法解答。其他选项代入意思都不匹配。

小题5:difference考察名词。根据上下文意思答题。从上两句“If a nest has four eggs and you remove one, the bird will not 3.However, if you remove two, the bird 4leaves.”的表达或第1 题change不难得出答案。D选项interval超纲了，意为间隔。

小题6:amazing 考察形容词，根据上下文意思以及第二题的surprisingly不难得出答案。

小题7:return考察动词。根据“The crow stayed away until the second man left, too.”的stayed away 以及第11题前“But the crow did not return to the nest until all the men were 11.”的return不难得出答案。

此题答题的关键是看重复出现until的结构语句。The bird did not 7until the man left the tower. /The crow stayed away until the second man left, too. /It was not until five men went into the tower and only four left that they were 12able to fool the crow.

小题8:idea 考察名词，上下义重现。根据上下文，后面的做法都表明这是一个主意想法。可以直接排除其他选项。

小题9:fool考察动词，原词重现，根据12题“12able to fool the crow.”的fool 以及14题“the children are 14fooled.”的词fooled可以得出答案。

小题10:repeated考察动词从上下文意思可以得出答案为重复做。此外，也可以根据常识中的实验是要反复进行的。

小题11:gone考察动词，同义重现，根据第10题前的语句“The crow stayed away until the second man left, too.”中的left和第12题的语句“It was not until five men went into the tower and only four left that they were 12able to fool the crow.”中的

left可以知道答案。

小题12:finally 考察副词根据上下文意思可知此处表示多次努力后最终成功。

小题13:small考察形容词反义重现及排除法可以解答。相对于three or four, 用small较恰当。single只能表示1 不能表示2。local和new与本文的内容没有任何关系。

小题14:often考察副词。根据上下文意思可以得出答案。前一句“For example, babies about fourteen months old almost always notice”的always 和本句中的“But when the number goes beyond three or four,”but可以得知此处答案为often.

小题15:ability考察名词，最后一段是对文章的总结。原词重现，根据第一段第一句和第二句话“Number sense is not the ability to count. It is the ability to recognize a 1in number. Human beings are born with this ability.”不难得出答案。

【考点定位：】考察六个动词，四个副词，二个形容词，三个名词

其中运用重现策略解题的题目有七道题。分别是 3（原词重现），7（原词重现或反义重现），8（上下义重现），9（原词重现），11（同义重现）13（反义重现），15（原词重现）

备考提示：副词这两年都考查了较多（往年要么一个或者没有），重现依然占有一定的比例。所以在平时的复习中选题或编题，应该按照这种情况作相应的调整。
