【题目】根据短文理解,选择正确答案。
Scientists in Argentina have created the world's first cow with two human genes that will enable it to produce human-like milk.
Genetic engineering was used to introduce the "mothers'milk" genes into the animal before birth, according to the National Institute of Agribusiness Technology in Buenos Aires.
As an adult, the cloned cow "will produce milk that is similar to that of humans", which will prove "a development of great importance for the nutrition of infants(婴儿)", said the institute. "The cloned cow, named Rosita ISA, is the first in the world with two human genes that contain the proteins present in human milk," said the statement.
In April, scientists in China published details of research showing that they had created dairy cows which produced milk containing proteins found in human breast milk. But the Argentine team said the Chinese only introduced one human gene, while their research involved two, meaning the milk will more closely resemble that of humans.
“Our goal was to raise the nutrition value of cows'milk by adding two human genes, which do good to the immune system of infants,” said Adrian Mutto, from the National University of San Martin which worked with the institute.
Cristina Kirchner, President of Argentina, said that the scientific institute made all Argentines proud. She also said that she had rejected the "honor" of having the cow named after her. "They came to tell me that the name is Cristina, but what woman would like to have a cow named after her? It appeared to me to be more proper to call it Rosita.”

B.be more similar to
C.have more nutrition than
D.be more different from
(3)What can be inferred from Cristina Kirchner's statements?
A.She was quite satisfied with the research done by the institute.
B.She considered it an honor to name the special cow.

D.She refused to give a name to the cow out of self-respect.
【答案】
(1)C
(2)B
(3)A
【解析】本文主要讲了阿根廷的科学家创造出了世界上第一头含有两个人类基因的奶牛,目的是可以使得奶牛产的牛奶含有和人类母乳中相似的营养成分,从而提高牛奶的营养,增加婴儿的免疫力。
(1)C 主旨大意题。本文主要讲了通过克隆奶牛,使得它产出和人类母乳相似的牛奶。故选C。
(2)B 词义猜测题。根据文中But the Argentine team said the Chinese only introduced one human gene, while their research involved two, meaning the milk will more closely resemble that of humans.可知,中国的科学家引用了人类的一个基因来使得牛奶中包含和人类母乳相似的蛋白质,而阿根廷的科学家引入两个基因会使得牛奶更加和母乳相似,所以more closely resemble意思指的是更加相似。故选B。
(3)A 推理判断题。根据文中最后一段的Cristina Kirchner, President of Argentina, said that the scientific institute made all Argentines proud.可知,她对机构做出的这项研究很满意。故选A。
