英语六级仔细阅读复习与答案

　　Color vision in each eye comes from six to seven million structures called cones. Under ideal conditions, every cone can “see” the entire rainbow spectrum of visible colors, but one type of cone is most sensitive to red, another to green, a third to blue.

　　Rods and cones send their messages pulsing an average 20 to 25 times per second along the optic nerve. We see an image for a fraction of a second longer than it actually appears. In movies, reels of still photographs are projected onto screens at 24 frames per second, tricking our eyes into seeing a continuous moving picture.

　　Like apparent motion, color vision is also subject to unusual effects. When day gives way to night, twilight brings what the poet T.S. Eliot called “the violet hour.” A light levels fall, the rods become progressively less responsive. Rods are most sensitive to the shorter wavelengths of blue and green, and they impart a strange vividness to the garden’s blue flowers.

　　However, look at a white shirt during the reddish light of sunset, and you’ll still see it in its “true” color—white, not red. Our eyes are constantly comparing an object against its surroundings. They therefore observe the effect of a shift in the color of illuminating on both, and adjust accordingly.

　　The eyes can distinguish several million graduations of light and shade of color. Each waking second they flash tens of millions of pieces of information to the brain, which weaves them incessantly into a picture of the world around us.

　　Yet all this is done at the back of each eye by a fabric of sensors, called the retina, about as wide and as thick as a postage stamp. As the Renaissance inventor and artist Leonardo da Vinci wrote in wonder, “Who would believe that so small a space could contain the images of all the universe?”

　　1.Visual illusions often take place when the image of reality is ___.

　　A.matched to six to seven million structures called cones.

　　B.confused in the body’s sensors of both rods and cones.

　　C.interpreted in the brain as what must be the case.

　　A.cones

　　D.spectrum

　　A.in short wavelengths

　　B.as color pictures

　　C.by a ganglion cell

　　D.along the optic nerve.

　　4.Twenty-four still photographs are made into a continuous moving picture just because ___.

　　A.the image we see usually stays longer than it actually appears.

　　B.we see an object in comparison with its surroundings.

　　C.the eyes catch million pieces of information continuously.

　　D.rods and cones send messages 20 to 25 times a second.

　　5.The author’s purpose in writing the passage lies in ___.

　　A.showing that we sometimes are deceived by our own eyes.

　　B.informing us about the different functions of the eye organs.

　　C.regretting that we are too slow in the study of eyes.

　　D.marveling at the great work done by the retina.

　　The word religion is derived from the Latin noun religio, which denotes both earnest observance of ritual obligations and an inward spirit of reverence. In modern usage, religion covers a wide spectrum of meaning that reflects the enormous variety of ways the term can be interpreted. At one extreme, many committed believers recognize only their own tradition as a religion, understanding expressions such as worship and prayer to refer exclusively to the practices of their tradition. Although many believers stop short of claiming an exclusive status for their tradition, they may nevertheless use vague or idealizing terms in defining religion for example, true love of God, or the path of enlightenment. At the other extreme, religion may be equated with ignorance, fanaticism, or wishful thinking.

　　By defining religion as a sacred engagement with what is taken to be a spiritual reality, it is possible to consider the importance of religion in human life without making claims about what it really is or ought to be. Religion is not an object with a single, fixed meaning, or even a zone with clear boundaries. It is an aspect of human experience that may intersect, incorporate, or transcend other aspects of life and society. Such a definition avoid the drawbacks of limiting the investigation of religion to Western or biblical categories such as monotheism (belief in one god only) or to church structure, which are not universal. For example, in tribal societies, religion unlike the Christian church usually is not a separate institution but pervades the whole of public and private life.

　　In Buddhism, gods are not as central as the idea of a Buddha. In many traditional cultures, the idea of a sacred cosmic order is the most prominent religious belief. Because of this variety, some scholars prefer to use a general term such as the sacred to designate the common foundation of religious life.

　　Religion in this understanding includes a complex of activities that cannot be reduced to any single aspect of human experience. It is a part of individual life but also of group dynamics. Religion includes patterns of behavior but also patterns of language and thought. It is sometimes a highly organized institution that sets itself apart from a culture, and it is sometimes an integral part of a culture. Religious experience may be expressed in visual symbols, dance and performance, elaborate philosophical systems, legendary and imaginative stories, formal ceremonies, and detailed rules of ethical conduct and law. Each of these elements assumes innumerable cultural forms. In some ways there are as many forms of religious expression as there are human cultural environments.
