答案

答案：D

题目分析：为了经受南极内陆气候的考验，泰山站建设中使用了很多最好的材料。泰山站的建设表明意识对改造客观世界其有指导作用，表现在钢材方面，一般耐低温钢材只能耐受-40℃ 的低温，而泰山站的俐材圾低可耐受-70℃至-100℃，尊重客观规律是造福人类的前提，体现在外墙涂层方面，秦山站的彩涂板上涂有一层氟碳层，能有效抵挡紫外线的照射，被称为南极建筑材料中最好的“防晒霜”。世界的物质性是客观的，不以人的意志为转移的，科技创新是利用规律造福人类，而不能改变规律，因此本题选D。

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（乌鸦）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.

A．Importantly

B．Surprisingly

C．Disappointedly

D．Fortunately

D．deliberately

A．appointment

D．explanation

B．temporarily
