　　阅读下面的短文。每篇短文的后面有五个问题，每个问题有四个备选答案。请根据短文的内容选择最佳答案。每个试题计3分,共计15分。

　　Reports of cryptic species have increased dramatically over the past two decades with the advent of relatively inexpensive DNA sequencing technology.Markus Pfenninger and Klaus Schwenk，of the Goethe-Universitat，in Frankfurt1，Germany，analyzed all known data on cryptic animal species and discovered that they are found in equal proportions throughout all major branches of the animal kingdom and occur in equal numbers in all biogeographieal regions.

　　Im extremely surprised by their results, says Alex Smith of the University of Guelph2 in Ontario3，Canada.Its a call to arms to keep doing the broad kind of genetic studies that we are doing.

　　Examples of cryptic species include the African elephant. A 2001 study found the elephants were actually two genetically distinct，non-interbreeding species，the African bush elephant and the African elephant. The species are currently listed as vulnerable and threatened，respectively，by the World Conservation Union 4.

　　In the early 1900s misidentification of mosquito species based on morphology confused attempts to control malaria in Europe.Ultimately，what was thought to be a single species was actually made up of six sibling species，only three of which transmitted the disease.The basic unit in biology is always the species，and you have to know what you are dealing with, Pfenninger says.Much previous research is now no longer used，he says，because it is not clear what species was being studied.5kriptik5tAksCnp

　　biodiversity n.生物多样性 taxonomic adj.分类

　　morphologyn.形态学 malaria n.疟疾5reptail5sibliNp

　　temperateadj. 温带的

　　2. the University of Guelph：圭尔夫大学。该校成立于1964年，是一所公立的综合性大学。在2005年加拿大综合类大学评比中，圭尔夫大学名列第3名，是全加拿大最著名的高等学府之一。

　　4. the World Conservation Union：世界自然保护联盟。全球最大、最重要的自然保护网络机构，它集合了82个国家、111个政府机构、800多个非政府组织以及来自181个国家的约1万多名科学家和专家，形成了世界环保领域里独一无二的全球性合作关系。

　　A The results of the research can help the development of many other researchareas.

　　C The results of the research can help our understanding of infectious diseaseevolution.

　　2. What was scientists understanding of cryptic species?

　　B They were mostly found in insects find reptiles.

　　D Both B and C.

　　A Not yet.

　　C They will know the answer in another one or two years;

　　4. Which of the following about the African bush elephant and the African elephant is true?

　　B They are interbreeding species.

　　D They depend on each other for survival.

　　A identified only one mosquito species instead of six species.

　　C thought there was only one mosquito species.

　　答案与题解：

　　1. D 短文的第一段第二句的大意是，研究结果为广泛的研究领域提供启示，包括生物多样性研究，还能帮助我们理解传染疾病及其演变。所以，选项A、B、C都是正确的，它们不是答案。选项D的适者生存的内容文章中没有提及，因此是本题的答案。

　　3. A 第三段和第五段提供了答案。第三段的倒数第二句中的Until...no one will know just how many cryptic species exist.其意思就是人们目前还不了解。第五段的最后一句也说明了研究者目前对此尚未了解。

　　5. A 短文最后一段告诉我们，由于对蚊子种类不了解，20世纪初期疟疾曾肆虐欧洲，最终，科学家才了解到蚊子这一物种不是由一个种类而是由六个种类组成。所以，应该选择A。
