Employers need to better understand people who are disabled. Most of us take offence at the assumption that collecting Social Security Income can provide us everything we need. Unemployment is humiliating and awfully boring, and there’s no meaning there. Excluding someone because he or she has a disability that does not affect performance is equivalent to wrongs such as hiring based on race. Everyone deserves to have the opportunity to do a good job, and as a result have a sense of pride in being a part of society.

A sense of smell is something we are born with. Or is it?Until recently scientists believed that the commonsense view was wrong: research had suggested that we learn to distinguish between pleasant and unpleasant smells by experience. From early experiments that involved asking children between three and five years old what they thought of certain smells, researchers concluded that children must learn their appreciation of pleasant and unpleasant smells as they get older, rather than being born with it. One of the most surprising results of these tests was that the children said they liked the smell of faeces nearly as often as they said they liked banana.Psychologist Hilary Schmidt understandably found this research hard to accept. She looked at the way the tests were conducted, and applied lessons from other work on child psychology to design her own experiments. She noted that children younger than five will often answer ‘Yes’ to leading questions even if the answers are contradictory. She therefore decided to set her experiment up as a game. She asked the children if they would give a particular smelly thing to Oscar the Grouch, a popular television character who lives in a dustbin and likes ‘smelly’ things, or to Big Bird, another television character who likes ‘nice’ things. She found that the children distinguished between pleasant and unpleasant smells in much the same way as an adult. With the help of younger and younger subjects, she hopes to shed light on the importance of the inherited component of the sense.Children younger than seven or eight are notoriously bad at recognizing what an object is from its shape alone. Schmidt points to an experiment she has carried out with children under five who were given a large styrofoam ball and a small, but heavy, lead ball to compare. After they had a chance to feel the two, she took the balls away, and showed them another pair of Styrofoam and lead ball. When she asked them which of the two would be the heavier, they invariably pointed to the Styrofoam ball just because it was bigger. Despite their earlier experience, they had not grasped the idea of what an object is made of—its substance—as well as size and shape. But in other experiments when she introduced odors, she found that children under five understood that smell was an important characteristic of substance, and children could use a scent to recognize substance irrespective of the shape or size in which it was presented to them.Schmidt has also found that girls are more sensitive to smell than boys. The sex difference is well known in adults, but not in children. Explaining the difference in adults has centered on the suggestion that as girls get older, they tend to take part in activities such as cooking, which train them to distinguish between smells. Another suggestion was that after puberty, female hormones bring about some change in the olfactory equipment. But Schmidt’s observations that the sex difference exists in children does not fit in with either explanation.31. According to the text, it is well-known that our sense of smell is ______.32. Which would Hilary Schmidt most probably agree to?33. Schmidt’s styrofoam and lead ball experiment shows that younger children ______.34. The word “subjects” (Para. 3) most probably means ______.35. From the last sentence of the text, we can infer that Schmidt may ______.

This week we will be celebrating the 200th anniversary of the birth of Charles Darwin, one of Britain’s most extraordinary scientists. His theory of evolution, one of the greatest discoveries of all time, gives us a way of understanding the connectedness of all life and the uniqueness of human life within it. Together with other branches of scientific exploration, evolution begins to unfold and illuminate the interplay of forces that make our universe such an extraordinary dynamic reality. In this sense, science is itself a journey of learning and exploration. This I find exciting and humbling.Towards the end of his life Darwin wrote: “It seems to me absurd to doubt that a man may be an ardent Theist and an evolutionist.” The science opens me not only to puzzles and to questions about the world I live in; it leads me to marvel at its complexity. Here, I find science is a good friend to my faith. It also calls me to a journey of learning and understanding. One of the things that mars our culture is the fracture between faith and science. It impoverishes our inquiry into the realities that make up our life and world. This is a false opposition.If we see the two as fundamentally opposed—science endangering and undermining faith, or faith obstructing knowledge—then distortions are produced on both sides. For example, some Christians argue for “Young Earth Creationism” or Intelligent Design as an alternative to evolutionary theory. Creationism is the belief that the biblical stories of Creation as described in the Book of Genesis are literally true.Is genuine Christianity obliged to adopt any of these positions? No, it is not. Belief in creation is not equivalent to any one of them. It is a mistake to treat the theology of creation in the Book of Genesis as a scientific textbook. It does unfold a profound and valid truth about the world in which we live, its order and purpose. The Book of Genesis speaks about the relationship between God and creation and especially about the place of humanity in that relationship. That wonderful narrative of creation offers us a first vision of an “ecology of holiness” in which every material and living thing has a place and its creativity is consecrated in goodness by God. The account of creation in Genesis is pointing us beyond the question “how?” to the question “why?” Ultimately, science as well as faith must come to that most fundamental of all questions: the question of meaning and purpose.31. According to the author, Darwin’s theory of evolution shows that ______.32. Which of the following would Darwin most probably agree to?33. The author finds science “humbling” because it ______.34. The author believes that The Book of Genesis is true in that it ______.35. In the author’s opinion, the relationship between science and faith is ______.

Apart from the Moon and occasional comets and asteroids, Venus is often our nearest neighbor. Its orbit brings it closer to Earth than any other planet—only 26 million miles away at certain times. Despite that proximity, for a long time it was generally termed “the planet of mystery.” This is because the atmosphere of Venus is so dense and so cloud-laded that its surface is permanently hidden from sight.The first attempt to learn more about Venus was to analyze its upper atmosphere using spectroscopic methods. In size and mass, Venus is almost the equal of Earth, and its gravitational field is only slightly weaker than ours, so that logically it might be expected to have the same kind of atmosphere—but this is emphatically not so. Scientists found that the main constituent of its atmosphere is carbon dioxide. Since this is a heavy gas that would be expected to sink, it was reasonable to assume that carbon dioxide made up most of the atmosphere down to ground level. Carbon dioxide acts in the manner of a greenhouse, trapping the Sun’s heat, so it followed that Venus was likely to be a very torrid sort of world.Yet opinions differed. According to one theory, the clouds contained a great deal of water. It was even claimed that the surface might be largely ocean covered, in which case: the atmosphere carbon dioxide would have fouled the water and produced seas of soda water. Another intriguing theory made Venus very similar to the Earth of over 200 million years ago. There would be marshes, luxuriant vegetation of the fern and horsetail variety, and primitive life-forms such as giant dragonflies. If so, then Venus might presumably evolve the same way Earth has done.In 1962 the American probe Mariner 2 bypassed Venus at less than 22,000 miles and gave us our first reliable information. The surface proved to be very hot indeed; we now know that the maximum temperature is almost 500°C. The atmosphere really is almost pure carbon dioxide, and those shining clouds are rich in sulfuric acid. All ideas of a pleasant, oceanic Venus had to be abandoned. In 1975 Venera 9, a Russian automatic lander, visited Venus and sent back pictures directly from the surface. The scene—a rocky, scorched landscape—could hardly be more hostile. Subsequent probes have confirmed this impression.Why is Venus so unlike Earth? The answer can only lie in its lesser distance from the Sun. It seems that in the early days of the solar system the Sun was less luminous than it is now, in which case Venus and Earth may have started to evolve along the same lines, but when the Sun became more powerful the whole situation changed. Earth, at 93 million miles, was just out of harm’s way, but Venus, at 67 million, was not. The water in oceans vaporized, the carbonates were driven out of the rocks, and in a relatively short time or the cosmic scale, Venus was transformed from a potentially life-bearing world into the inferno of today.25.
