Question

Number sense is not the ability to count. It is the ability to recognize a    1   in 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    4   leaves. This means that the bird knows the    5   between two and three.

Another interesting experiment showed a bird's    6   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    7   until 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    9   the bird. The crow stayed away until the second man left, too. The experiment was    10   with 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    12   able 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    13   group. But when the number goes beyond three or four, the children are    14   fooled.

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

【解析】

1.change 考察動詞后文中的從four, one, two都說明是在變化。根據(jù)上下文意思答題。其他選項A rise 意為上升，B pattern 意為樣式， D trend 意為趨向。

2.Surprisingly 考察副詞，根據(jù)上下文句意，此處表示驚訝，居然動物也具有這種能力。

3.notice 考察動詞，原詞重現(xiàn)，F(xiàn)or example, babies about fourteen months old almost always notice if something is taken away from a    13   ）意為注意、留意。此題的C hatch選項意為孵化，該詞不常見，出處在人教新課標版Book8 U2。

4.generally 考察副詞。根據(jù)上下文意思可以得出答案。此句意為“鳥普遍會離開”。另外，此題也可以通過排除法解答。其他選項代入意思都不匹配。

5.difference 考察名詞。根據(jù)上下文意思答題。從上兩句“If a nest has four eggs and you remove one, the bird will not    3  .However, if you remove two, the bird    4   leaves.”的表達或第1 題change不難得出答案。D選項interval超綱了，意為間隔。

6.amazing 考察形容詞，根據(jù)上下文意思以及第二題的surprisingly不難得出答案。

7.return 考察動詞。根據(jù)“The crow stayed away until the second man left, too.”的stayed away 以及第11題前“But the crow did not return to the nest until all the men were    11  .”的return不難得出答案。

此題答題的關(guān)鍵是看重復(fù)出現(xiàn)until的結(jié)構(gòu)語句。The bird did not    7   until 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    12   able to fool the crow.

8.idea 考察名詞，上下義重現(xiàn)。根據(jù)上下文，后面的做法都表明這是一個主意想法。可以直接排除其他選項。

9.fool 考察動詞，原詞重現(xiàn)，根據(jù)12題“   12   able to fool the crow.”的fool 以及14題“the children are    14   fooled.”的詞fooled可以得出答案。

10.repeated 考察動詞 從上下文意思可以得出答案為重復(fù)做。此外，也可以根據(jù)常識中的實驗是要反復(fù)進行的。

11.gone 考察動詞，同義重現(xiàn)，根據(jù)第10題前的語句“The crow stayed away until the second man left, too.”中的left和第12題的語句“It was not until five men went into the tower and only four left that they were    12   able to fool the crow.”中的

left可以知道答案。

12.finally 考察副詞根據(jù)上下文意思可知此處表示多次努力后最終成功。

13.small 考察形容詞 反義重現(xiàn)及排除法可以解答。相對于three or four, 用small較恰當。single只能表示1 不能表示2。local和new與本文的內(nèi)容沒有任何關(guān)系。

14.often 考察副詞。根據(jù)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可以得知此處答案為often.

15.ability 考察名詞，最后一段是對文章的總結(jié)。原詞重現(xiàn)，根據(jù)第一段第一句和第二句話“Number sense is not the ability to count. It is the ability to recognize a    1   in number. Human beings are born with this ability.”不難得出答案。

【考點定位：】考察六個動詞，四個副詞，二個形容詞，三個名詞

其中運用重現(xiàn)策略解題的題目有七道題。分別是 3（原詞重現(xiàn)），7（原詞重現(xiàn)或反義重現(xiàn)），8（上下義重現(xiàn)），9（原詞重現(xiàn)），11（同義重現(xiàn)）13（反義重現(xiàn)），15（原詞重現(xiàn)）

備考提示：副詞這兩年都考查了較多（往年要么一個或者沒有），重現(xiàn)依然占有一定的比例。所以在平時的復(fù)習(xí)中選題或編題，應(yīng)該按照這種情況作相應(yīng)的調(diào)整。
