今天小编给大家带来的主要内容是2015年12月3日雅思阅读真题回忆,本次考试终于回归正常，取消了AB卷。三篇文章分别关于深海鱼类，美国电影发展及科技的弊端。大家可以参考剑桥真题相似文章，以便更好地备考接下来的雅思阅读考试。
A卷：
Passage 1：
题目：Deep sea fish
题型：填空题7+判断题6
文章大意：
一个德国科学家在埃及红海潜水想看看15m以下到底有没有红光(理论上是没有任何光线的)。结果在海地20m的地方看见了红色的鱼。即使取下红色滤光片用肉眼也可以看见。在这个深度不可能有光线，所以猜想是荧光，但是没有设备验证，只能尽可能多地拍照片。回德国之后证实了确实是荧光，50种鱼都有这种荧光，是皮下的细胞里的晶体里发出的，不是晶体本身，可能是晶体里的荧光蛋白，这个蛋白可能是细菌制造的。鱼用这个红光来识别种群，标识位置，吓退敌人，掩盖自己，捕捉猎物。

The fish of the deep-sea are among the strangest and most elusive creatures on Earth. In this deep unknown lie many unusual creatures that have yet to be studied. Since many of these fish live in regions where there is no natural rely solely on their eyesight for locating prey and mates and avoiding predators; deep-sea fish have evolved appropriately to the extreme sub-photic region in which they live. Many of these organisms are blind and rely on their other senses, such as sensitivities to changes in local pressure and smell, to catch their food and avoid being caught. Those that aren’t blind have large and sensitive eyes that can use bioluminescent light. These eyes can be as much as 100 times more sensitive to light than human eyes. Also, to avoid predation, many species are dark to blend in with their environment.
Many deep-sea fish are bioluminescent, with extremely large eyes adapted to the dark. Bioluminescent organisms are capable of producing light biologically through the agitation of molecules of luciferin, which then produce photons of light. This process must be done in the presence of oxygen. These organisms are common in the mesopelagic region and below (200m and below). More than 50% of deep-sea fish as well as some species of shrimp and squid are capable of bioluminescence. About 80% of these organisms have phosphors – light producing glandular cells that contain luminous bacteria bordered by dark colorings. Some of these phosphors contain lenses, much like those in the eyes of humans, which can intensify or lessen the emanation of light. The ability to produce light only requires 1% of the organism's energy and has many purposes: It is used to search for food and attract prey, like the anglerfish; claim territory through patrol; communicate and find a mate; and distract or temporarily blind predators to escape. Also, in the mesopelagic where some light still penetrates, some organisms camouflage themselves from predators below them by illuminating their bellies to match the color and intensity of light from above so that no shadow is cast. This tactic is known as counter illumination.
The life cycle of deep-sea fish can be exclusively deep water although some species are born in shallower water and sink uponmaturation. Regardless of the depth where eggs and larvae reside, they are typically pelagic. This planktonic – drifting – lifestyle requires neutral buoyancy. In order to maintain this, the eggs and larvae often contain oil droplets in their plasma. When these organisms are in their fully matured state they need other adaptations to maintain their positions in the water column. In general, water’s density causes up thrust – the aspect of buoyancy that makes organisms float. To counteract this, the density of an organism must be greater than that of the surrounding water. Most animal tissues are denser than water, so they must find an equilibrium to make them float. Many organisms develop swim bladders (gas cavities) to stay afloat, but because of the high pressure of their environment, deep-sea fishes usually do not have this organ. Instead they exhibit structures similar to hydrofoils in order to provide hydrodynamic lift. It has also been found that the deeper a fish lives, the more jelly-like its flesh and the more minimal its bone structure. They reduce their tissue density through high fat content, reduction of skeletal weight – accomplished through reductions of size, thickness, and mineral content – and water accumulation makes them slower and less agile than surface fish.

Passage 2：
题目： American Cinema
题型：配对题11+ 选择题2
文章大意：美国电影的发展史简介
参考文章(仅供参考，非原文)：
The history of film is an account of the historical development of the medium known variously as cinema, motion pictures, film, or the movies. The history of film spans over 100 years, from the latter part of the 19th century to the present day. Motion pictures developed gradually from a carnival novelty to one of the most important tools of communication and entertainment, and mass median the 20th century and into the 21st century. Most films before 1930 were silent. Motion picture films have substantially affected arts, technology, and politics. The cinema was invented during the 1890's, during what is now called the industrial revolution. It was considered a cheaper, simpler way to provide entertainment to the masses. Movies would become the most popular visual art form of the late Victorian age. It was simpler because of the fact that before the cinema people would have to travel long distances to see major dioramas or amusement parks. With the advent of the cinema this changed. During the first decade of the cinema's existence, inventors worked to improve the machines for making and showing films. The cinema is a complicated medium, and before it could be invented, several technological requirements had to be met.
