During the past generation, the American middle-class family that once could count on hard work and fair play to keep itself financially secure had been transformed by economic risk and new realities. Now a pink slip, a bad diagnosis, or a disappearing spouse can reduce a family from solidly middle class to newly poor in a few months.In just one generation, millions of mothers have gone to work, transforming basic family economics. Scholars, policymakers, and critics of all stripes have debated the social implications of these changes, but few have looked at the side effect: family risk has risen as well. Today’s families have budgeted to the limits of their new two-paycheck status. As a result, they have lost the parachute they once had in times of financial setback – a back-up earner (usually Mom) who could go into the workforce if the primary earner got laid off or fell sick. This “added-worker effect” could support the safety net offered by unemployment insurance or disability insurance to help families weather bad times. But today, a disruption to family fortunes can no longer be made up with extra income from an otherwise-stay-at-home partner.During the same period, families have been asked to absorb much more risk in their retirement income. Steelworkers, airline employees, and now those in the auto industry are joining millions of families who must worry about interest rates, stock market fluctuation, and the harsh reality that they may outlive their retirement money. For much of the past year, President Bush campaigned to move Social Security to a saving-account model, with retirees trading much or all of their guaranteed payments for payments depending on investment returns. For younger families, the picture is not any better. Both the absolute cost of healthcare and the share of it borne by families have risen – and newly fashionable health-savings plans are spreading from legislative halls to Wal-Mart workers, with much higher deductibles and a large new dose of investment risk for families’ future healthcare. Even demographics are working against the middle class family, as the odds of having a weak elderly parent – and all the attendant need for physical and financial assistance – have jumped eightfold in just one generation.From the middle-class family perspective, much of this, understandably, looks far less like an opportunity to exercise more financial responsibility, and a good deal more like a frightening acceleration of the wholesale shift of financial risk onto their already overburdened shoulders. The financial fallout has begun, and the political fallout may not be far behind.【小题1】Today’s double-income families are at greater financial risk in that ________A．the safety net they used to enjoy has disappeared.B．their chances of being laid off have greatly increased.C．they are more vulnerable to changes in family economics.D．they are deprived of unemployment or disability insurance.【小题2】As a result of President Bush’s reform, retired people may have ________A．a higher sense of security.B．less secured payments.C．less chance to invest.D．a guaranteed future.【小题3】According to the author, health-savings plans will ________A．help reduce the cost of healthcare.B．popularize among the middle class.C．compensate for the reduced pensions.D．increase the families’ investment risk.【小题4】It can be inferred from the last paragraph that ________A．financial risks tend to outweigh political risks.B．the middle class may face greater political challenges.C．financial problems may bring about political problems.D．financial responsibility is an indicator of political status.

When a rare disease ALD threatened to kill the four-year-old boy Lorenzo, his parents refused to give up hope. Doctors explained that there was no cure for ALD, and that he would probably die within three years. But Lorenzo’s parents set out to prove the doctors wrong.The parents devoted themselves to keeping their son alive and searching for a cure. But doctors and the families of other ALD patients often refused to take them seriously. They thought the efforts to find a cure were a waste of time, and drug companies weren’t interested in supporting research into such a rare disease.However, the parents still refused to give up and spent every available hour in medical libraries and talking to anyone who would help. Through trial and error, they finally created a cure from ingredients (调料) commonly found in the kitchen. The cure, named "Lorenzo’s Oil", saved the boy’s life. Despite the good results, scientists and doctors remained unconvinced. They said there was no real evidence that the oil worked and that the treatment was just a theory. As a result, some families with ALD children were reluctant to try it.Finally, the boy’s father organized an international study to test the oil. After ten years of trials, the answer is: the oil keeps ALD children healthy.【小题1】Doctors said that Lorenzo might die within three years because_____ .A.they had never treated the disease beforeB.Lorenzo was too young to be curedC.no cure had been found for ALDD.ALD was a rare disease【小题2】The families of other ALD patients thought that _____ .A.the research for the new cure would cost too much moneyB.the efforts of Lorenzo’s parents were a waste of timeC.Lorenzo’s parents would succeed in finding a cureD.Lorenzo’s oil was a real cure for ALD【小题3】Scientists and doctors believed that Lorenzo’s Oil_____.A.was really effectiveB.was a success storyC.only worked in theoryD.would save the boy’s life【小题4】From the passage we can conclude that_____.A.doctors remain doubtful of the effectiveness of the cureB.many ALD patients still refuse to use the oilC.various cures have been found for ALDD.the oil really works as a cure for ALD

Artificial（假的）flowers are used for scientific as well as for decorative purposes. They are made from a variety of materials, such as wax and glass, so skill-fully that they can scarcely be distinguished from natural flowers. In making such models, painstaking and artistry are called for, as well as thorough knowledge of plant structure. The collection of glass flowers in the Botanical Museum of Harvard University is the most famous in North America and is widely known throughout the scientific world. In all, there are several thousand models in colored glass, the work of two artist-naturalists, Leopold Blaschka and his son Rudolph. The intention was to have the collection represent at least one member of each flower family native to the United States. Although it was never completed. It contains more than seven hundred species representing 164 families of flowering plants, a group of fruits showing the effect of fungus diseases, and thousands of flower parts and magnified details. Every detail of these is accurately reproduced in color and structure. The models are kept in locked cases as they are too valuable and fragile for classroom use. 【选项】 1. Which of the following is the best title for the passage? A. An Extensive Collection of Glass Flowers B. The Lives of Leopold and Rudolph C. Flowers Native to the United States D.
