1、单选题：
Questions 1 to 5 are based on the following passage.‎The phrase almost completes itself; midlife crisis. It's the stage in the middle of the journey when people feel youth vanishing, their prospects narrowing and death approaching.‎    There's only one problem with the cliche (套话). It isn't true.‎    "In fact, there is almost no hard evidence for midlife crisis other than a few small pilot studies conducted decades ago," Barbara Hagerty writes in her new book, Life Reimagined. The bulk of the research shows that there may be a pause, or a shifting of gears in the 40 s or 50 s, but this shift "can be exciting, rather than terrifying".‎    Barbara Hagerty looks at some of the features of people who turn midlife into a rebirth. They break routines, because "autopilot is death". They choose purpose over happiness—having a clear sense of purpose even reduces the risk of Alzheimer's disease. They give priority to relationships, as careers often recede (逐渐淡化).‎    Life Reimagined paints a picture of middle age that is far from gloomy. Midlife seems like the second big phase of decision-making. Your identity has been formed; you've built up your resources; and now you have the chance to take the big risks precisely because your foundation is already secure.‎    Karl Barth described midlife precisely this way. At middle age, he wrote, "the sowing is behind; now is the time to reap. The run has been taken; now is the time to leap. Preparation has been made; now is the time for the venture of the work itself."‎    The middle-aged person, Barth continued, can see death in the distance, but moves with a "measured haste" to get big new things done while there is still time.‎    What Barth wrote decades ago is even truer today. People are healthy and energetic longer. We have presidential candidates running for their first term in office at age 68, 69 and 74. A longer lifespan is changing the narrative structure of life itself. What could have been considered the beginning of a descent is now a potential turning point—the turning point you are most equipped to take full advantage of.‎1.

6、单选题：
Questions 6 to 10 are based on the following passage.‌ In spring, chickens start laying again, bringing a welcome source of protein at winter's end. So it's no surprise that cultures around the world celebrate spring by honoring the egg.‌    Some traditions are simple, like the red eggs that get baked into Greek Easter breads. Others elevate the egg into a fancy art, like the heavily jewel-covered "eggs" that were favored by the Russians starting in the 19th century.‌    One ancient form of egg art comes to us from Ukraine. For centuries, Ukrainians have been drawing complicated patterns on eggs. Contemporary artists have followed this tradition to create eggs that speak to the anxieties of our age; Life is precious, and delicate. Eggs are, too.‌    "There's something about their delicate nature that appeals to me," says New Yorker cartoonist Roz Chast. Several years ago, she became interested in eggs and learned the traditional Ukrainian technique to draw her very modern characters. "I've broken eggs at every stage of the process—from the very beginning to the very, very end."‌    But there's an appeal in that vulnerability. "There's part of this sickening horror of knowing you're walking on the edge with this, that I kind of like, knowing that it could all fall apart at any second." Chast's designs, such as a worried man alone in a tiny rowboat, reflect that delicateness.‌Traditional Ukrainian decorated eggs also spoke to those fears. The elaborate patterns were believed to offer protection against evil.‌    "There's an ancient legend that as long as these eggs are made, evil will not prevail in the world," says Joan Brander, a Canadian egg-painter who has been painting eggs for over 60 years, having learned the art from her Ukrainian relatives.‌    The tradition, dating back to 300 B. C., was later incorporated into the Christian church. The old symbols, however, still endure. A decorated egg with a bird on it, given to a young married couple, is a wish for children. A decorated egg thrown into the field would be a wish for a good harvest.‌6  Why do people in many cultures prize the egg?‌​‌
选项：
A: A. It is a welcome sign of the coming of spring.
B: B. It is their major source of protein in winter.
C: C. It can easily be made into a work of art.
D: D. It can bring wealth and honor to them.

8、单选题：
8  Why have contemporary artists continued the egg art tradition?​‏​
选项：
A: A. Eggs serve as an enduring symbol of new life.
B: B. Eggs have an oval shape appealing to artists.
C: C. Eggs reflect the anxieties of people today.
D: D. Eggs provide a unique surface to paint on.
答案: 【 C. Eggs reflect the anxieties of people today.】

1、单选题：
Questions 1 to 5 are based on the following passage.‎  As a person who writes about food and drink for a living, I couldn't tell you the first thing about Bill Perry or whether the beers he sells are that great. But I can tell you that I like this guy. That's because he plans to ban tipping in favor of paying his servers an actual living wage.‎    I hate tipping.‎    I hate it because it's an obligation disguised as an option. I hate it for the post-dinner math it requires of me. But mostly, I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry.‎    Most of you probably think that you hate tipping, too. Research suggests otherwise. You actually love tipping! You like to feel that you have a voice in how much money your server makes. No matter how the math works out, you persistently view restaurants with voluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.‎    One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you. Well, if this were true, we would all be slipping a few 100-dollar bills to our doctors on the way out their doors, too. But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one. Waiters, keen observers of humanity that they are, are catching on to this: in one poll, a full 30% said they didn't believe the job they did had any impact on the tips they received.‎So come on, folks: get on board with ditching the outdated tip system. Pay a little more upfront for your beer or burger. Support Bill Perry's pub, and any other bar or restaurant that doesn't ask you to do drunken math.‎1.  What can we learn about Bill Perry from the passage?‎‍‎
选项：
A: A. He runs a pub that serves excellent beer.
B: B. He intends to get rid of the tipping practice.

6、单选题：
Questions 6 to 10 are based on the following passage.‏In the past, falling oil prices have given a boost to the world economy, but recent forecasts for global growth have been toned down, even as oil prices sink lower and lower. Does that mean the link between lower oil prices and growth has weakened?‏    Some experts say there are still good reasons to believe cheap oil should heat up the world economy. Consumers have more money in their pockets when they're paying less at the pump. They spend that money on other things, which stimulates the economy.‏    The biggest gains go to countries that import most of their oil like China, Japan, and India. But doesn't the extra money in the pockets of those countries' consumers mean an equal loss in oil-producing countries, cancelling out the gains? Not necessarily, say economic researcher Sara Johnson. " Many oil producers built up huge reserve funds when prices were high, so when prices fall they will draw on their reserves to support government spending and subsidies(补贴)for their consumers. "‏    But not all oil producers have big reserves. In Venezuela, collapsing oil prices have sent its economy into free-fall.‏    Economist Carl Weinberg believes the negative effects of plunging oil prices are overwhelming the positive effects of cheaper oil. The implication is a sharp decline in global trade, which has plunged partly because oil-producing nations can't afford to import as much as they used to.‏    Sara Johnson acknowledges that the global economic benefit from a fall in oil prices today is likely lower than it was in the past. One reason is that more countries are big oil producers now, so the nations suffering from the price drop account for a larger share of the global economy.‏    Consumers, in the U. S. at least, are acting cautiously with the savings they're getting at the gas pump, as the memory of the recent great recession is still fresh in their mind. And a number of oil-producing countries are trimming their gasoline subsidies and raising taxes, so the net savings for global consumers is not as big as the oil price plunge might suggest.‏6. What does the author mainly discuss in the passage?‏‌‏
选项：
A: A. The reasons behind the plunge of oil prices.
B: B. Possible ways to stimulate the global economy.
C: C. The impact of chape oil on global economic growth.
D: D. The effect of falling oil prices on consumer spending.
答案: 【 C. The impact of chape oil on global economic growth.】

7、单选题：
7. Why do some experts believe cheap oil will stimulate the global economy?​‏​
选项：
A: A. Manufacturers can produce consumer goods at a much lower cost.
B: B. Lower oil prices have always given a big boost to the global economy.
C: C. Oil prices may rise or fall but economic laws are not subject to change.
D: D. Consumers will spend their savings from cheap oil on other commodities.
答案: 【 D. Consumers will spend their savings from cheap oil on other commodities.】

8、单选题：
8. What happens in many oil-exporting countries when oil prices go down?‌‌‌
选项：
A: A. They suspend import of necessities from overseas.

C: C. They use their money reserves to back up consumption.
D: D. They try to stop their economy from going into free-fall.
答案: 【 C. They use their money reserves to back up consumption.】

9、单选题：
9. How does Carl Weinberg view the current oil price plunge?‍
选项：
A: A. It is one that has seen no parallel in economic history.
B: B. Its negative effects more than cancel out its positive effects.
C: C. It still has a chance to give rise to a boom in the global economy.
D: D. Its effects on the global economy go against existing economic laws.
答案: 【 B. Its negative effects more than cancel out its positive effects.】

10、单选题：
10. Why haven't falling oil prices boosted the global economy as they did before?‌
选项：
A: A. People are not spending all the money they save on gas.
B: B. The global economy is likely to undergo another recession.
C: C. Oil importers account for a larger portion of the global economy.
D: D. People the world over are afraid of a further plunge in oil prices.

Unit 4-test 2

1、填空题：
Talking rubbish‍A. The stretch of the Pacific between Hawaii and California is virtually empty. There are no islands, no shipping lanes, no human presence for thousands of miles—just sea, sky, and rubbish. The prevailing currents cause flotsam (水面漂浮物) from around the world to accumulate in a vast becalmed patch of ocean. In places, there are a million pieces of plastic per square kilometer. That can mean as much as 112 times more plastic than plankton (浮游生物), the first link in the marine food chain. All this adds up to perhaps 100 million tonnes of floating garbage, and more is arriving every day.B. Wherever people have been—and some places where they have not—they have left waste behind. Litter lines the world's roads; dumps dot the landscape; slurry and sewage slosh into rivers and streams. Up above, thousands of fragments of defunct spacecraft careen (猛冲) through space, and occasionally more debris is produced by collisions such as the one that destroyed an American satellite in mid-February. Ken Noguchi, a Japanese mountaineer, estimates that he has collected nine tonnes of rubbish from the slopes of Mount Qomolangma during five clean-up expeditions. There is still plenty left.C. The average Westerner produces over 500kg of municipal waste a year—and that is only the most obvious portion of the rich world's discards. In Britain, for example, municipal waste from households and businesses makes up just 24 percent of the total. In addition, both developed and developing countries generate vast quantities of construction and demolition debris, industrial effluent, mine tailings, sewage residue, and agricultural waste. Extracting enough gold to make a typical wedding ring, for example, can generate three tonnes of mining waste.D. Rubbish may be universal, but it is little studied and poorly understood. Nobody knows how much of it the world generates or what it does with it. In many rich countries, and most poor ones, only the patchiest of records are kept. That may be understandable: By definition, waste is something its owner no longer wants or takes much interest in.E. Ignorance spawns (引起) scares, such as the fuss surrounding New York's infamous garbage barge, which in 1987 sailed the Atlantic for six months in search of a place to dump its load, giving many Americans the false impression that their country's landfills had run out of space. It also makes it hard to draw up sensible policies: Just think of the endless debate about whether recycling is the only way to save the planet—or an expensive waste of time.F. Rubbish can cause all sorts of problems. It often stinks, attracts vermin, and creates eyesores. More seriously, it can release harmful chemicals into the soil and water when dumped, or into the air when burned. It is the source of almost four percent of the world's greenhouse gases, mostly in the form of methane from rotting food—and that does not include all the methane generated by animal slurry and other farm waste. And then there are some really nasty forms of industrial waste, such as spent nuclear fuel, for which no universally accepted disposal methods have thus far been developed.G. Yet many also see waste as an opportunity. Getting rid of it all has become a huge global business. Rich countries spend some $120 billion a year disposing of their municipal waste alone and another $150 billion on industrial waste, according to CyclOpe, a French research institute. The amount of waste that countries produce tends to grow in tandem with their economies, and especially with the rate of urbanization. So waste firms see a rich future in places such as India and Brazil, which at present spend only about $5 billion a year collecting and treating their municipal waste.H. Waste also presents an opportunity in a grander sense: as a potential resource. Much of it is already burned to generate energy. Clever new technologies to turn it into fertilizer or chemicals or fuel are being developed all the time. Visionaries see a future in which things like household rubbish and pig slurry will provide the fuel for cars and homes, doing away with the need for dirty fossil fuels. Others imagine a world without waste, with rubbish being routinely recycled. As Bruce Parker, the head of the National Solid Wastes Management Association (NSWMA), an American industry group, puts it, "why fish bodies out of the river when you can stop them jumping off the bridge?"I. Until last s
