Question

Certain animals know without analysis the difference between a number of objects and a smaller number. In his book The Natural History of Selbourne (1786), the naturalist Gilbert White tells how he surreptitiously removed one egg a day from a kind of bird Plover’s nest, and how the mother laid another egg each day to make up for the missing one. He notes that other kinds of birds ignore the loss of a single egg, but if more than one egg has been removed, they will give up their nests. It has also been noted that a certain type of bees always provides five—never four, never six—caterpillars (毛虫) for each of their eggs so that their young have something to eat when the eggs have hatched out. Research has also shown that both mice and pigeons can be taught to distinguish between odd (奇数) and even (偶数) numbers of food pieces.
These have led some people to think that creatures can actually count. They also point to dogs that have been taught to respond to questions about numbers with the correct number of barks.
Animals respond to quantities only when they are connected to survive as in the case of the eggs, or survive as in the case of food. They can “count” only when the objects are present and only when the numbers involved are small—no more than seven or eight. In lab experiments, animals which are trained to count one kind of objects were unable to count any other type. What interests them are the objects, not the numbers. Animals’ achievements simply are not equal to evidence of counting. They only show the results of clever, careful training

Answer 1

CADD
这篇文章介绍动物有数字的意识，并通过一些实验来证明这点。
1.细节题：从第一段的句子：Certain animals know without analysis the difference between a number of objects and a smaller number. 可知作者提到Gilbert的书是为了证明动物有数字意识。选C
2.排除题：文章第一段的句子：removed one egg a day from a kind of bird Plover’s nest, ，It has also been noted that a certain type of bees always provides ，和Research has also shown that both mice and pigeons can be taught to distinguish between odd (奇数) and even (偶数) numbers of food pieces.可知作者提到BCD都能意识到数字，但没有说毛毛虫可以意识到数字。选A
3.猜词题：从句意看是作者偷偷每天从珩科鸟的鸟巢中拿掉一个蛋，选D
4.文章出处题：这篇文章介绍动物有数字的意识，应该是出自生物杂志。选D
