3、4-1Deer Populations Of The Puget Sound相关背景学习:Marsupials are any members of the mammalian infraclass Marsupialia. All e*tant marsupials are endemic to Australasia and the Americas. A distinctive characteristic common to these species is that most of the young are carried in a pouch. Well-known marsup
4、ials include kangaroos, wallabies, koalas, possums, opossums, wombats, and Tasmanian devils. Others include the numbat, the bandicoot, the bettong, the bilby, the quoll, and the quokka.Marsupials represent the clade originating from the last common ancestor of e*tant metatherians. Like other mammals
5、 in the Metatheria, they give birth to relatively undeveloped young that often reside with the mother in a pouch, for a certain amount of time. Close to 70% of the 334 e*tant species occur on the Australian continent (the mainland, Tasmania, New Guinea and nearby islands). The remaining 100 are foun
6、d in the Americas primarily in South America, but thirteen in Central America, and one in North America, north of Me*ico.Ta*onomically, the two primary divisions of Marsupialia are: American and Australian marsupials. The order Microbiotheria (which has only one species, the monito del monte) is fou
7、nd in South America, but is believed to be more closely related to Australian marsupials. There are many small arboreal species in each group. The term opossum is used to refer to American species (though possum is a common diminutive), while similar Australian species are properly called possums. A
8、gain, shrew opossums are more closely related to australidephians than to true opossums.2022年9月24日托福阅读真题第二篇 印刷术带来的进展 历史类原文回顾:印刷术早发现于德国,然后再欧洲各个国家主要城市广泛运用。随着大众需求的上升,press开始广泛印刷书籍,并且开始运用各国的方言包括德语法语等语言),而不是学术运用的Latin and Greek被上述语言,成了少部分运用的语言工具。这些语言的运用也让欧洲人形成了民族认同感,渐渐的,书籍开始与policy无关,而仅仅取决于人们自己的需求。而且印刷的问
9、世带来了很多的书籍,以前的手稿只能人手一份,而且不能编辑,不利于文化沟通。有了印刷之后,可以出版更多权威的书籍,列举亚里士多德的例子。另外press不仅仅是印刷的地方,而是各种功能的集合体。相关背景学习Printing is a process for reproducing te*t and images using a master form or template. The earliest e*amples include Cylinder seals and other objects such as the Cyrus Cylinder and the Cylinders of N
10、abonidus. The earliest known form of woodblock printing came from China dating to before 220 A.D. Later developments in printing include the movable type, first developed by Bi Sheng in China. Johannes Gutenberg introduced mechanical movable type printing to Europe in the 15th century. His printing
11、press played a key role in the development of the Renaissance, Reformation, the Age of Enlightenment, and the scientific revolution and laid the material basis for the modern knowledge-based economy and the spread of learning to the masses.Modern large-scale printing is typically done using a printi
12、ng press, while small-scale printing is done free-form with a digital printer. Though paper is the most common material, it is also frequently done on metals, plastics, cloth and composite materials. On paper it is often carried out as a large-scale industrial process and is an essential part of pub
13、lishing and transaction printing.2022年9月24日托福阅读真题第三篇 一种会发电信号的鱼 生命类原文回顾:这篇阅读重复了2022年7月9日的一篇文章,而且在2022年9月5日也相同涌现过。该鱼发出的电信号有用性强。它可以援助鱼类定位找到精确的出口,可以援助鱼类内部相互沟通和互动。比如鱼类之间的交配行为,雌鱼和雄鱼能够依据对方发出的信号确认是否合适。它也是鱼类进击和示弱的表现。这个电信号可以有多种方式来表达;比如加强,停顿,减弱。鱼类为了信号不相互干扰,会停掉自己的信号去检测其他鱼的信号,但是这一个过程持续时间比较短。这种鱼属于沟通时间快速的一类。但也不是全部
14、鱼为了识别其他鱼而停止释放自己的信号。还有另一种鱼可以同时留意自己和身边的鱼的轻快。原文部分重现Weak Electric Systems In Fish1. Some blind elephantnose fish produce weak electric signals that are used for detecting objects in their surroundingsa phenomenon called active electrolocation. These fish have specialized electric organs that discharge e
15、ither in pulses or in a wave-like fashion, depending on the species. Although discharges follow one another almost continuously throughout the life of the fish, their power level is much too low to be detected by human handlers but potent enough to create a stable electric field around the body of t
16、he fish. When an object enters into this electric field, it causes distortions in the current that are detected by electroreceptor organs distributed over the fishs skin.2. A weak electric system may have several uses, including the e*ploration of novel environments. For e*ample, blind elephantnose
17、fish can easily find the only opening that allows them to cross through a newly installed partition within their aquarium, even though they cannot see it with their eyes. Their electric sense must be implicated because when these individuals become electrically silent (unable to use their electric s
18、ystem through denervation of their electric organs), they can no longer find the opening.3. During the 1970s, biologists became interested in the role of the weak electric system not only as a means of electrolocation but also as a means of electrical communication between individual fish. Communica
19、tion is possible because the rate and waveform of the electric discharges can vary between species, between se*es, between individuals, or even between situations in the same individual. Moreover, some fish can temporarily interrupt their normally continuous train of discharges, and these pauses can
20、 be full of meaning. The effective range of communication by electric signals can reach a little over 1 meter depending on water resistance.第一段:弱电系统的背景知识以及运作的过程第二段:弱电系统的几种用法,举例:探究新环境第三段:生物学家发觉弱电系统的新功能:个体间沟通,论证这种功能的可能性第四段:弱电系统的新功能:同类繁殖第五段:弱电系统的新功能:与侵略性有关第六段:(第三段引出)问题,解决问题(两种带电接收器),举例:一种鱼类的沟通过程第七段:介绍了
21、一种鱼类的行为(防止干扰弱电系统而作出的回应),以及这种回应实现的过程相关背景学习Electromagnetic field receptors (ampulla of Lorenzini) and motion detecting canals in the head of a sharkActive electrolocation. Conductive objects concentrate the field and resistive objects spread the field.Electroreception, or electroception, is the abilit
22、y to detect electric fields or currents. Some fish, such as catfish and sharks, have organs that detect weak electric potentials on the order of millivolts. Other fish, like the South American electric fishes Gymnotiformes, can produce weak electric currents, which they use in navigation and social
23、communication. In sharks, the ampulla of Lorenzini are electroreceptor organs. They number in the hundreds to thousands. Sharks use the ampullae of Lorenzini to detect the electromagnetic fields that all living things produce.This helps sharks (particularly the hammerhead shark) find prey. The shark
24、 has the greatest electrical sensitivity of any animal. Sharks find prey hidden in sand by detecting the electric fields they produce. Ocean currents moving in the magnetic field of the Earth also generate electric fields that sharks can use for orientation and possibly navigation.Electric field pro
25、*imity sensing is used by the electric catfish to navigate through muddy waters. These fish make use of spectral changes and amplitude modulation to determine factors such shape, size, distance, velocity, and conductivity. The abilities of the electric fish to communicate and identify se*, age, and hierarchy within the species are also made possible through electric fields. EF gradients as low as 5nV/cm can be found in some saltwater weakly electric fishThe paddlefish (Polyodon spathula) hunts plankton using thousands of tiny passive electroreceptors located on its e*tended snout, or rostrum.
