题文
阅读理解。 With only about 1, 000 pandas left in the world, China is desperately trying to clone (克隆) the animal andsave 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. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A &
M's College of Veterinary 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 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 _____. A. make efforts to clone the endangered pandas
B. save endangered animals from dying out
C. collect DNA of endangered animals to study
D. transfer the nuclear of one animal to another 2. According to Professor Kraemer, the major problem in cloning pandas would be the lack of _____. A. available panda eggs
B. host animals
C. qualified researchers
D. enough money 3. Which of the following should be the best title for the passage? A. China's Success in Pandas Cloning
B. The First Cloned Panda in the World
C. Exploring the Possibility to Clone Pandas
D. China -the Native Place of Pandas Forever 4. From the passage we know that _____. A. Kraemer and his team have succeeded in cloning a dog
B. scientists try to implant a panda's egg into a rabbit
C. Kraemer will work with Chinese scientists in clone researches
D. about two thousand of species will probably die out in a century 题型：未知难度：其他题型

考点
据考高分专家说，试题“阅读理解。 With only.....”主要考查你对 [健康环保类阅读 ]考点的理解。健康环保类阅读
健康环保累阅读概念：
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。体裁有记叙文、 说明文、议论文和各种应用文。
健康环保类文章阅读技巧：
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考，理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文，从结构上看大致可分为三个部分：
第一部分一般是文章的首段，主要用来提出文章的主题，即文章想要阐述、说明的主要内容；
第二部分是文章的主体，可由若干个段落组成，对文章的主题进行展开说明；
第三部分是结尾段，对文章的主题进行归纳总结。这类文章多用一般现在时，而且一般多使用客观性词语表述。有时为了强调客观性，也常使用被动语态。
从近几年的考试题来看，科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节，很多同学对此类文章感到费解。但一般的科普类文章都是就事论事，需要逻辑推理和想象的时候较少，因此此类阅读题也没有同学们想象中的那么难，只要多加训练，就能较好地答题。
