A scientific team is studying the thinking ability of eleven-and-a-half-month-old children. The test is a simple one. The baby watches a sort of show on a small stage. In Act One of the show, a yellow cube is lifted from a blue box, and moved across the stage. Then it is returned to the box. This is repeated 6 times. Act Two is similar except that the yellow cube is smaller.
    Baby boys do not react at all to the difference in the size of the cube. But girls immediately become excited. The scientists interpret the girls’ excitement as meaning they are trying to understand what they have just seen. They are wondering why Act Two is odd and how it differs from Act One. In other words, the little girls are reasoning.
    This experiment certainly does not definitely prove that girls start to reason before boys, but it provides a clue that scientists would like to study more carefully.
    Already it is known that bones, muscles and nerves develop faster in baby girls. Perhaps it is early nerve development that makes some infant girls show more intelligence than infant boys. Scientists also found that nature seems to give another boost to girls: baby girls usually talk at an earlier age than boys do. Scientists think that there is a physical reason for this. They believe that the nerve endings in the left side of the brain develop faster in girls than in boys, and it is this side of the brain that strongly influences an individual’s ability to use language and remember things.
    Questions 26-30 are based on the passage you have just heard:
    26. What is the difference between Act One and Act Two in the test?
    27. How do the scientists interpret their observation from the experiment?
    28. What does the speaker say about the experiment?
    29. According to scientists, what is another advantage given to girls by nature?
    30. What does the speaker mainly talk about?

选项 A、The difference between boys and girls.
B、The language development of different stages.
C、The thinking ability of boys and girls at the same age.
D、The physical development of boys and girls.

答案C

解析 短文从最开始就提到了,一个科学小组在11个半月的孩子身上做了一个关于思维能力 (thinking ability)的实验。后面讲述的就是实验的设置、过程和结果,因此本题正确答案为C。
