暑假练习（一）Youve now heard it so many time, you can probably repeat it in your sleep. President Obama will no doubt _51_the point publicly when he gets to Beijing: the Chinese need to _52_more; they needbelieve it or notto become more like Americans, for the sake of the global economy.And its all true. _53_the other side of that equation is that the U.S. needs to save more. For the moment, American households actually are doing so. After the personal-savings rate _54_to zero in 2005, the shock of the economic _55_last year prompted people to snap _56_their wallets. In China, the household-savings rate exceeds 20%. It is partly for policy_57_. As weve seen, wage earners are expected to _58_not only their children but their aging parents. And there is, to date, only theflimsiest(脆弱的) of publicly-funded health care and pension systems, which increases incentives for individuals to save _59_they are working. But China is a society that has _60_esteemed personal financialprudence(谨慎). There is no _61_that will change anytime soon, even if the government creates a better social safety net and successfully encourages greater consumer spending.Why does the U.S. need to learn a little frugality (节俭)? Because healthy savings rates are one of the surest indicators of a countrys long-term financial health. High savings lead, over time, to increased investment, which in turn generates productivity gains, _62_and job growth. _63_, savings are the seed corn of a good economic harvest.The U.S. government thus needs to act as well. By running _64_deficits, it is dis-saving, even as households save more. Peter Orszag, Obamas Budget Director, _65_called the U.S. budget deficits unsustainable and hes right. To date, the U.S. has seemed unable to see the consequences of spending so much more than is taken in. That needs to change. 51. A. playB. takeC. makeD. give52.

Others want to eat more fish and less red meat, in addition to reducing the amount of food they eat. But, they can improve their diets even more with just a simple addition. American researchers have found that a diet rich in spices can help reduce the harmful effects of eating high fat meals.Pennsylvania State University Associate Professor Shiela West led an investigation of the health effects of a spice-rich diet. Her team knew that a high-fat meal produces high levels of triglycerides (甘油三脂), a kind of fat, in the blood. She said, “If this happens too frequently, or if triglyceride levels are raised too much, your risk of heart disease is increased.”As part of the study, her team prepared meals on two separate days for six men between the ages of 30 and 65. The men were overweight, but healthy. The researchers added about 30 milliliters of spices to each serving of the test meal, which included chicken curry, Italian herb bread and a cinnamon (肉桂树皮)biscuit. The meal for the control group was the same, but it did not include any spices. During the experiment, the researchers removed blood from the men every 30 minutes for three hours. They found that antioxidant activity (抗氧化活性) in the blood of the men who ate the spicy meal was 13 percent higher than it was for the men who did not. In addition, insulin (胰岛素) activity dropped by about 20 percent in the men who ate the spicy food.Shiela West says many scientists think that oxidative stress leads to heart disease. And what exactly is oxidative stress? Think of an apple that has been cut in half and set aside for half an hour or so. The cut side of the apple turns brown. That is a simple explanation of what happens when oxidative stress comes in contact with the inside and outside of our bodies. Professor West says, “Antioxidants, like spices, may be important in reducing oxidative stress and thus reducing the risk of chronic disease.” She adds that the level of spices used in the study provided the same amount of antioxidants found in 150 milliliters of red wine or about 38 grams of dark chocolate.66. What does the author advise people to do in their diets? A. Eating large amount of food. B. Eating less fruits and vegetables. C. Eating more vegetables and fish. D. Eating small amount of food with spices. 67. What is the function of spices according to the passage? A. To help people lose weight. B. To cure chronic disease. C. To reduce the risk of heart disease. D. To cause oxidative stress.68. What happened to the men who ate the spicy meal according to the experiment?A. The antioxidant activity in their blood became increased. B. The insulin activity in their body became increased.C. The level of triglyceride in their blood was increased.D. The oxidative stress in their body was strengthened.69. What does Professor West show by citing the example of a half apple? A. The whole thing can be divided into two parts. B. It implies oxidative stress is harmful to our health.C. An apple is the only food that contains antioxidants. D. We can keep diseases away if we have an apple a day. ( B )Which tablet computer should YOU be buying: They are this years must have. and theres a style to suit everyone？Best for young childrenLeapPad Explorer 2, 68Aimed at children between three and nine (though a nine-year-old might find it a little simple), it comes in pink or blue and with five built-in education games (you can buy more). Besides, the LeapPad does not allow access to the internet so it is impossible for your child to stumble across anything inappropriate.Pros: The education games are well-designed, the built-in video camera is a fun way to play at being a film director.Cons: Some of the games are shockingly expensive.

We think of the United States as a land of unlimited possibility, not so much a classless society but as a place where class is mutablea place where brains, energy and ambition are what counts, not the circumstances of ones birth. The Economic Mobility Project, an ambitious research initiative led by Pew Charitable Trusts, looked at the economic fortunes of a large group of families over time, comparing the income of parents in the late 1960s with the income of their children in the late 1990s and early 2000s. Here is the finding: The rags to riches story is much more common in Hollywood than on Main Street. Only 6 percent of children born to parents with family income at the very bottom move to the top.That is right, just 6 percent of children born to parents who ranked in the bottom fifth of the study sample, in terms of income, were able to bootstrap their way into the top fifth. Meanwhile, an incredible 42 percent of children born into that lowest quintile are still stuck at the bottom, having been unable to climb a single rung of the income ladder.It is noted that even in Britain-a nation we think of as burdened with a hidebound class system-children who are born poor have a better chance of moving up. When the three studies were released, most reporters focused on the finding that African-Americans born to middle-class or upper middle-class families are earning slightly less, in inflation-adjusted dollars, than did their parents.One of the studies indicates, in fact, that most of the financial gains white families have made in the past three decades can be attributed to the entry of white women into the labor force. This is much less true for African-Americans.The picture that emerges from all the quintiles, correlations and percentages is of a nation in which, overall, the current generation of adults is better off than the previous one, as one of the studies notes.The median income of the families in the sample group was $55,600 in the late 1960s; their childrens median family income was measured at $71,900. However, this rising tide has not lifted all boats equally. The rich have seen far greater income gains than have the poor.Even more troubling is that our notion of America as the land of opportunity gets little support from the data. Americans move fairly easily up and down the middle rungs of the ladder, but there is stickiness at the ends four out of ten children who are born poor will remain poor, and four out often who are born rich will stay rich.74. What did the Economic Mobility Project find in its research?A. Children from low-income families are unable to bootstrap their way to the top.B. Hollywood actors and actresses are upwardly mobile from rags to riches.C. The rags to riches story is more fiction than reality.D. The rags to riches story is only true for a small minority of whites.75. It can be inferred from the undertone of the writer that America, as a classless society, should _.A. perfect its self-image as a land of opportunityB. have a higher level of upward mobility than BritainC. enable African-Americans to have exclusive access to well-paid employmentD. encourage the current generation to work as hard as the previous generation76.

Inequality persists between whites and blacks in financial gains.C. Middle-class families earn slightly less with inflation considered.D.

Inequality in Wealth.D. America Not Land of Opportunity.It is 2035. You have a job, a family and you are about 40 years old! Welcome to your future life. Getting ready for work, you pause in front of the mirror. “Turn red,” you say. Your shirt changes from sky blue to deep red. Tiny preprogrammed electronics are rearranged in your shirt to change its color. Looking into the mirror, you find it hard to believe youre 40. You look much younger. With amazing progress in medicine, people in your generation may live to be 150 years old. You are not even middle-aged!As you go into the kitchen and prepare to pour your breakfast cereal into a bowl, you hear, “To lose weight, you shouldnt eat that,” from your shoes. They read the tiny electronic code on the cereal box to find out the nutrition details. You decide to listen to your shoes. “Kitchen, what can I have for breakfast?” A list of possible foods appears on the counter as the kitchen checks its food supplies. P.F. Productions“Ready for your trip to space?” you ask your son and daughter. In 2005 only specially trained astronauts went into spaceand very few of them. Today anyone can go to space for day trips or longer vacations. Your best friend even works in space. Handing your children three strawberries each, you add, “The doctor said you need these for space travel.” Thanks to medical progress, vaccination shots (防疫针) are a thing of the past. Ordinary foods contain the vaccines. With the strawberries in their mouths, the kids head for the front door. Its time for you to go to work. Your car checks your fingerprints and unlocks the doors. “My office, Autopilot,” you order. Your car drives itself down the road and moves smoothly into traffic on the highway. You sit back and unroll your e-newspaper. The latest news downloads and fills the viewer. Looking through the pages, you watch the news as video film rather than read it.

(26)_ cleaned up the river as part of a weeklong environmental camp. Like one in three American rivers, this river is so polluted that its unsafe for swimming or fishing. Still, Susan, (27)_ has just completed her third summer camp on the river cleanup, sees a change in this river. “Since we started three years ago, the river is getting a lot (28)_(clean),” she says. Environmental scientists praise the teenagers for removing garbage (29)_ can harm wild life. Water birds, for example, can die of plastic bottle rings and get cut by tiny metals. Three years ago, when the cleanup started, garbage was everywhere. But this year the teenagers can row their boats fast. By the end of the six-hour cleanup, they (30)_(remove) enough garbage to fill more than two large trucks. “(31)_(see) all that garbage in the river makes people begin to care about environmental issues,” Susan says. She hopes that when others read that, she and her peers care enough (32)_(clean) it up, maybe they would think twice before they throw garbage into the river.(B)Dave Fuss lost his job (33)_(drive) a truck for a small company in west Michigan. His wife, Gerrie, was still working in the local school cafeteria, and the price of everything was rising. The Fusses were at risk of joining the millions of Americans who have lost their homes in recent years. Then Dave and Gerrie received a timely gift-$7,000，a legacy (遗产) from their neighbors Ish and Arlene Hatch, who died in (34)_ accident. “It really made a difference (35)_ we were going under financially.” says Dave. But the Fusses werent the only folks in Alto and the neighboring town of Lowell to receive unexpected legacy from the Hatches. Dozens of other families (36)_(touch) by the Hatches generosity. In some cases, it was a few thousand dollars; in others, it was more than $100,000. It surprise
