关于动物间信息传递的托福阅读文章
如今托福阅读的背景知识要求越来越多，托福阅读题材也越来越广泛，如果大家不能在新托福阅读的复习时对各种资料有一个了解的话考试的时候会很困难，下面的材料是关于动物间的信息传递的知识，希望对大家有帮助。 新托福阅读准备之托福阅读题材：动物间的信息传递托福阅读原文： The daytime quality of light in forests varies withthe density of the
vegetation, the angle of the Sun, and the amount of cloud inthe sky. Both
animals and plants have different appearances in thesevarious lighting
conditions. A color or pattern that is relatively indistinct inone kind of
light may be quite conspicuous in another. In the varied andconstantly changing light environment of the forest, an
animal must be able to send visual signals to members of itsown species and at
the same time avoid being detected by predators. An animalcan hide from
predators by choosing the light environment in which itspattern is least
visible. This may require moving to different parts of theforest at different
times of the day or under different weather conditions, or itmay be achieved by
changing color according to the changing light conditions.Many species of
amphibians (frogs and toads) and reptiles (lizards and
snakes) are able to
change their color patterns to camouflage themselves. Somealso signal by
changing color. The chameleon lizard has the most strikingability to do this.
Some chameleon species can change from a rather dullappearance to a full riot
of carnival colors in seconds. By this means, they signal theirlevel of
aggression or readiness to mate. Other species take intoaccount the changing conditions of light by
performing their visual displays only when the light is
favorable. A male bird
of paradise may put himself in the limelight by displaying hisspectacular
plumage in the best stage setting to attract a female. Certainbutterflies move
into spots of sunlight that have penetrated to the forest floorand display by
opening and closing their beautifully patterned wings in thebright spotlights.
They also compete with each other for the best spot of
sunlight. Very little light filters through the canopy of leaves andbranches in a
rain forest to reach ground level—or close to the
ground—and at those levels the
yellow-to-green wavelength predominate. A signal might bemost easily seen if it
is maximally bright. In the green-to-yellow lighting
conditions of the lowest
levels of the forest, yellow and green would be the brightestcolors, but when
an animal is signaling, these colors would not be very visibleif the animal was
sitting in an area with a yellowish or greenish background.The best signal
depends not only on its brightness but also on how well itcontrasts with the
background against which it must be seen. In this part of therain forest,
therefore, red and orange are the best colors for signaling,and they are the
colors used in signals by the ground-walking Australianbrush turkey. This
species, which lives in the rain forests and scrublands of theeast coast of
Australia, has a brown-to-black plumage with bare,
bright-red skin on the head
and a neck collar of orange-yellow loosely hanging skin.During courtship and
aggressive displays, the turkey enlarges its colored neckcollar by inflating
sacs in the neck region and then flings about a pendulouspart of the colored
signaling apparatus as it utters calls designed to attract orrepel. This
impressive display is clearly visible in the light spectrumilluminating the
forest floor. Less colorful birds and animals that inhabit therain forest tend to rely
on forms of signaling other than the visual, particularly overlong distances.
The piercing cries of the rhinoceros hornbill characterize theSoutheast Asian
rain forest, as do the unmistakable calls of the gibbons. Indensely wooded
environments, sound is the best means of communicationover distance because in
comparison with light, it travels with little impediment fromtrees and other
vegetation. In forests, visual signals can be seen only at shortdistances,
where they are not obstructed by trees. The male riflebirdexploits both of
these modes of signaling simultaneously in his courtshipdisplay. The sounds
made as each wing is opened carry extremely well overdistance and advertise his
presence widely. The ritualized visual display communicatesin close quarters
when a female has approached. 通过上面关于动物间的信息传递这个话题的托福阅读题材介绍已经又为大家做了不少准备，希望能帮助大家在新托福阅读中取得一个先机，这样托福阅读就能取得进步了。智课培训新托福名师一对一： 【课程特色】 托福并不算出国考试中最难的一门，在它上面，SAT词汇量和逻辑思维要求更高。但它却是最重要和基础的第一关。我们推荐托福一对一的形式，因为在这个关键的年纪，也许某个细节就会成为决定一生的转折点，孩子需要的关注远远高于你的预期。 智课托福一对一培训，提倡深入浅出的课程，亲切随和的老师，看得见的进步以及摸得着的成长。随之进行的，还有更深层的授课。我们遇到过当了30年教授的家长，和孩子沟通中遇到难题，最终在智课老师的协助下顺利说服孩子的例子;也有在上课时因无法坚持而痛哭，后来在我们反复开导和交心下，继续努力下去的学生。这种真挚的感情纽带，让我们成为了真正的朋友。 对于想要冲刺高分的学生——无论是哪个阶段，智课的托福一对一授课将以自由的方式，带领你去领悟和感受学习的乐趣，并将单纯的托福备考，变成一种形成自己英语思维的过程。不被过程蒙蔽双眼，追求考试背后的意义，是我们坚守的学习理念。 【授课教材】 新托福官方指南 TPO全真新托福试题 内部讲义
