单选题Passage 1 The aroma of chocolate perfumes the air of the Rue d'Assas in Paris. Entering Christian Constant's state-of-the-art boutique, you find yourself in the kingdom of Paris's king of chocolate, where the humble cocoa bean is turned into mouth-watering chocolate Easter eggs. Constant, who is a chef, admits that chocolate is his passion and main interest in life. He first developed a fascination with chocolate when he was working for Gaston Len6tre, a famous French pastry chef. Every year he has a theme for decorating Easter eggs: this year his decorations are inspired by "Art Nouveau". Tonight he has a dinner for 130 to organize and he has to prepare a three-foot-high Art Nouveau-style Easter egg by noon tomorrow. This, for Constant, is a normal schedule. Constant believes that his chocolate creations are as much of a work of art as other sculptures. It is, therefore, understandable that the restaurant, which he opened last month, is situated in the National Monuments Museum in Paris. During the day the restaurant is a tearoom and offers chocolate in every imaginable form. Customers can choose from a selection of sweet chocolate desserts or try the more exotic spicy chocolates. Constant is also a professional "nose", working closely with the French Institute of Taste. He is capable of identifying 450 different tastes and flavors. Constant explains that the mouth, which can only taste four things--salt, sweet, acid and bitter-- is "stupid" in comparison to the nose. He believes that the nose is everything. In his book The Taste of Chocolate, he explains how in 1502 Christopher Columbus came across an island and went ashore. He was greeted by an Indian chief bearing gifts, among which were huge sacks of beans which Columbus thought was local currency. To his surprise, they prepared a drink for him. But Columbus, who disliked the odd bitter taste, continued on his travels, ignorant of the fact that he had just tasted cocoa. Like Columbus, Constant travels the cocoa countries where he checks quality and works with local experts. Quality can vary depending on the region, year, and method of preparation. According to Constant, Venezuela and Trinidad have the best cocoa beans, which they export all over the world either as beans or as cocoa. Constant, who is a hard worker, only sleeps three hours a night. He talks long into the night with members of a club he has formed. The club is called "The Chocolate Munchers". Their main official activity is to get together for monthly dinners where they eat a very tiny dinner and tons of chocolate desserts. "I am an addict," Constant admits, "and I don't want to be cured!/

单选题 On a four-day trip to Ethiopia, I had a dream. In my dream, I saw two men, one older and one younger, facing one another against a background of temples and pyramids.

单选题It's been called the Gig Economy, Freelance Nation, the Rise of the Creative Class, and the e-economy, with the "e" standing for electronic, entrepreneurial. Everywhere we look, we can see the U.S. workforce undergoing a massive change. No longer do we work at the same company for 25 years, waiting for the gold watch, expecting the benefits and security that come with full-time employment. We're no longer simply lawyers, or photographers, or writers. Instead, we're part-time lawyers-cure-amateur' photographers who write on the side. Today, careers consist of piecing together various types of work, juggling multiple clients, learning to be marketing and accounting experts, and creating offices in bedrooms/coffee shops. Independent workers abound. We call them freelancers, contractors, sole proprietors, consultants, temps, and the self-employed. This transition is nothing less than a revolution. We haven't seen a shift in the workforce so significant in almost 100 years since we transitioned from an agricultural to an industrial economy. Now, employees are leaving the traditional workplace and opting to piece together a professional life on their own. As of 2005, one-third of our workforce participated in this "freelance economy". Statistics show that number has only increased over the past six years. While the economy has unwillingly pushed some people into independent work, many have chosen it because of greater flexibility that lets them skip the dreary office environment and focus on more personally fulfilling projects. These trends will have an enormous impact on our economy and our society: We don't actually know the true composition of the new workforce. After 2005, the government stopped counting independent workers in a meaningful and accurate way. Studies have shown that the independent workforce has grown and changed significantly since then. Jobs no longer provide the protections and security that workers used to expect. The basics such as health insurance, protection from unpaid wages, a retirement plan, and unemployment insurance are out of reach for one-third of working Americans. Independent workers are forced to seek them elsewhere, and if they can't find or afford them, then they go without. Therefore, it's time to build a new support system that allows for the flexible and mobile way that people are working. This new, changing workforce needs to build economic security in profoundly new ways. For the new workforce, the New Deal is irrelevant. When it was passed in the 1930s, the New Deal provided workers with important protections and benefits but those securities were built for a traditional employer-employee relationship. The New Deal has not evolved to include independent workers. (424 words)

单选题Shaw's international fame was firmly established ______.

单选题Our physical development is largely directed by the genes that we inherit from our parents. At one time, psychologists waged vigorous debates about how much of our behavior is genetically determined and how much of it is learned. This was known as the nature-nurture controversy. We now know that this "either-or" question is largely meaningless, since behavior depends on the interaction between heredity (遗传) and environment. However, it is also dear that genetic factors do set limits on our behavioral capabilities, as illustrated most dramatically in certain genetically baaed birth disorders. Psychologists working in the field of behavior genetics study how behavior is influenced by biological factors and how favorable or unfavorable environmental conditions can affect an organism' s genetically inherited potential. Genetic theory began around 1865, when Gregor Mendel reported on his experiments with garden peas. Mendel showed that heredity involved the passing on of specific organic factors, not the simple blending of the parents' characteristics. These specific factors might produce visible characteristics in the offspring(后代), or they might simply be carried for possible transmission to another generation. In any case, the offspring of one set of parents did not all inherit the same traits. Early in the twentieth century, geneticists made an important distinction between genotype and phenotype. Genotype refers to the specific genetic makeup of an individual, while phenotype refers to the observable characteristics produced by that genetic endowment(才能). Genotype and phenotype axe not identical because not every gene is expressed in a visible trait and bemuse the expression of a genotypic trait may be modified by the environment. An individual's genetic coding is like the catalog of a giant library. Some of the coded directives are used on one occasion, some on another. Some are never used at all, either, because they are contradicted by stronger genetic directives or because the environment never calls them forth. For example, geneticists have discovered that chickens have retained the genetic code for teeth, yet, because the code is prevented from being expressed, hens' teeth remain a cliche for scarcity.
