Question

With only about 1,000 pandas left in the world, China is desperately trying to clone (克隆) the animal and save the endangered species(物种).That's a move similar to what a Texas A&M University researchers have been undertaking for the past five years in a project called “Noah's Ark”.

Noah's Ark is aimed at collecting eggs, embryos(胚胎)，semen and DNA of endangered animals and storing them in liquid nitrogen（氮）. If certain species should become extinct, Dr.Duane Kraemar, a professor in Texas A&M University Medicine, says there would be enough of the basic building blocks to reintroduce the species in the future.

It is estimated that as many as 2,000 species of mammals, birds reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the next 25 years.

This week, Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal.

The entire procedure could take from three to five years to complete.

“The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available(capable of being used) panda eggs could be a major problem，”Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A & M, the first–ever attempt at cloning a dog.

“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”

1.The aim of “Noah’s Ark” project is to________.

C. Exploring the Possibility to Clone Pandas

D. China---the Native Place of Pandas Forever

4.From the passage we know that _______.

C. Kraemer will work with Chinese scientists in clone researches

D. about two thousand species will probably die out in a century

【解析】

试题分析：文章讲述的是大熊猫是濒危物种，中国通过诺亚方舟计划正在想办法寻找克隆熊猫的方法。

1. B细节理解题。根据第一段With only about 1,000 pandas left in the world, China is desperately trying to clone (克隆) the animal and save the endangered species(物种).That's a move similar to what a Texas A&M University researchers have been undertaking for the past five years in a project called “Noah's Ark”.可知，“Noah’s Ark” project是为了保护濒危动物。故选B。

2.B词义猜测题。句意：但这可能是突破性的科学，如果它实施的话。 Pioneering：开创性的;首创的;先驱的。故选B。

3.C主旨大意题。文章讲述的是大熊猫是濒危物种，中国正在想办法寻找克隆熊猫的方法。故选C。

4.推理判断题。根据第三段It is estimated that as many as 2,000 species of mammals, birds reptiles will become extinct in over 100 years.可知，据估计，多达2000种的哺乳动物，鸟类爬行动物将在100年内灭绝。故选D。

考点：考查科普类阅读

【名师点睛】

科普类的阅读理解一般为介绍科学知识、社会知识的文章。阅读这类短文时，要以文章事实为中心进行思考。

答题技巧：

1. 加强整体意识，把握文章的主要内容。给重要的句子和关键词做上记号，特别是各段中心句，可以更快捷的答题。比如第30题：主旨大意题。文章讲述的是大熊猫是濒危物种，中国正在想办法寻找克隆熊猫的方法。故选C。

2. 审清题干，弄清楚问题的要点，从文章对应处寻找答案。

要熟悉科普类文章的结构特点。科普类文章一般由标题(Head line)，导语(Introduction)，背景(Back ground)，主体(Main body)和结尾(End)五部分构成。

标题是文章中心思想高度而又精辟的概括，但根据历年的高考情况来看，这类阅读理解材料一般不给标题，而要同学们选择标题。导语一般位于整篇文章的首段。背景交待一个事实的起因。

主体则对导语概括的事实进行详细叙述，这一部分命题往往最多，因此，阅读时，同学们要把这部分作为重点。比如第28题：B细节理解题。根据第一段With only about 1,000 pandas left in the world, China is desperately trying to clone (克隆) the animal and save the endangered species(物种).That's a move similar to what a Texas A&M University researchers have been undertaking for the past five years in a project called “Noah's Ark”.可知，“Noah’s Ark” project是为了保护濒危动物。故选B。

结尾往往也是中心思想的概括，并与导语相呼应，命题者常在此要设计一道推理判断题。比如第31题：推理判断题。根据第三段It is estimated that as many as 2,000 species of mammals, birds reptiles will become extinct in over 100 years.可知，据估计，多达2000种的哺乳动物，鸟类爬行动物将在100年内灭绝。故选D。
