9．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（嬰兒）"，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．"
25．What is the passage mainly about？C
A．The importance of genetic engineering．
B．Ways to improve mothers'milk．
C．A cloned cow to produce human-like milk．
D．Advanced agricultural technology in Argentina．
26．Which of the following can best replace"more closely resemble"in Paragraph 4？B
A．have more varieties than
B．be more similar to
C．have more nutrition than
D．be more different from
27．What can be inferred from Cristina Kirchner's statements？A
A．She was quite satisfied with the research done by the institute．
B．She considered it an honor to name the special cow．
C．She felt it improper to be named after the cow．
D．She refused to give a name to the cow out of self-respect．
分析 這是一篇新聞報道，屬記敘文體裁，介紹了阿根廷通過添加人類基因的方式培育出了"類人乳"牛．
解答 25．C．主旨大意題．根據(jù)科技新聞報道的特點，在文章第一段就會出現(xiàn)文章主題句，即 Scientists in Argentina have created the world's first cow with two human genes that will enable it to produce human-like milk．即可得出正確結(jié)論，阿根廷通過添加人類基因的方式培育出了"類人乳"牛，故選C．
26．B．詞義猜測題．第四段內(nèi)容介紹了中國培育了加入一個人類基因的�？梢员徽J為"human-like"，那么阿根廷加入兩個，足見是"更接近人乳"了，故選B．
27．A．推理判斷題．女總統(tǒng)的話the scientific institute"makes all Argentines proud"說明C 正確，她很滿意研究所的作為．A中說她認為給牛命名是一種榮耀，并未提及．最后一段，只要明確name和name after區(qū)別即可．be named after her 是以她的名字命名，而be named after the cow是以牛的名字命名；顯然B是錯誤的，而D中give a name to the cow是給牛起名的意思，故A不對．
點評 本文是一個科教類閱讀理解，題目涉及多道細節(jié)理解題，做題時結(jié)合原文和題目有針對性的找出相關語句進行仔細分析，結(jié)合選項選出正確答案．推理判斷題也是要在抓住關鍵句子的基礎上合理的分析才能得出正確答案，切忌胡亂猜測，一定要做到有理有據(jù)．
