填空题 {{B}}Questions 57 to 61 are based on the following passage.{{/B}} The human criterion for perfect vision is 20/20 for reading the standard lines on a Snellen eye chart without a hitch. The score is determined by how well you read lines of letters of different sizes from 20 feet away. But being able to read the bottom line on the eye chart does not approximate perfection as far as other species are concerned. Most birds would consider us very visually handicapped. The hawk, for instance, has such sharp eyes that it can spot a dime on the sidewalk while perched on top of the Empire State Building. It can make fine visual distinctions because it is blessed with one million {{I}}cones{{/I}} (视锥细胞) per square millimeter in its {{I}}retina{{/I}} (视网膜). And in water, humans are farsighted, while the kingfisher, swooping down to spear fish, can see well in both the air and water because it is endowed with two {{I}}foveae{{/I}}(凹窝)-areas of the eye, consisting mostly of cones, that provide visual distinctions. One fovea permits the bird, while in the air, to scan the water below with one eye at a time. This is called monocular vision. Once it hits the water, the other fovea joins in, allowing the kingfisher to focus both eyes, like binoculars, on its prey at the same time. A frog's vision is distinguished by its ability to perceive things as a constant motion picture. Known as "bug detectors", a highly developed set of cells in a frog's eyes responds mainly to moving objects. So, it is said that a frog sitting in a field of dead bugs wouldn't see them as food and would starve. The bee has a "compound" eye, which is used for navigation. It has 15,000 facets that divide what it sees into a pattern of dots, or mosaic. With this kind of vision, the bee sees the sun only as a single dot, a constant point of reference. Thus, the eye is a superb navigational instrument that constantly measures the angle of its line of flight in relation to the sun. A bee's eye also gauges flight speed. And if that is not enough to leave our 20/20 "perfect vision" paling into insignificance, the bee is capable of seeing something we can't—ultraviolet light. Thus, what humans consider to be "perfect vision" is in fact rather limited when we look at other species.However, there is still much to be said for the human eye. Of all the mammals, only humans and some primates can enjoy the pleasures of color vision.

填空题Slash Your Bills — 6 Ways to Keep More Cash Like a lot of hardworking couples, Ilah and Dennis Hardesty of Long Beach, California, live paycheck to paycheck. Their $1,200 monthly rent eats up about half of Dennis's take-home pay as a manager for a racing car engine manufacturer. Private school tuition for their three teens takes another $400 bite. Income from Ilah's two part-time jobs — as a fitness trainer and school secretary—disappears at the gas station and the grocery store. The bottom line? Even with no car payments and just $300 in credit card debt, the family barely gets by. "We don't have a penny in savings", says Ilah. "No, I actually do have one cent in my account". With inflation outpacing wage growth in recent years, it's not hard to find families like the Hardestys running out of money before they run out of month. According to the nonpartisan (无党派的) Economic Policy Institute, which studies lower-and middle-class economic trends, the median hourly wage of an American worker after inflation is less today than in 2003. The result is less buying power after the bills are paid. These days, inflation is hovering around three percent, so anyone who remembers the double-digit price spikes of the 1970s might wonder what all the fuss is about. But even moderate inflation takes its toll, says personal finance expert Jonathan Pond, author of You Can Do It! The Boomer's Guide to a Great Retirement. In fact, annual inflation of just three percent doubles the cost of living every 23 or 24 years. Meanwhile, some essential expenses — energy, health care, higher education — are far outpacing the inflation index. No wonder families are feeling pinched. Pinched doesn't have to mean powerless, though. Here, then, are six ways to save money on the big bills.Education Options Here's a pop quiz: Who's turned out move current CEOs of S health care costs have been outpacing inflation, which is one reason why employers are shifting more of the insurance burden to individuals. To control the expense, many people are opting for higher deductibles and lower monthly premiums. What's more, says Pond, "four-fifths of Americans enjoy pretty darn (非常) good health and could be safe choosing a policy with fewer bells and whistles. If no one in your family uses expensive pharmaceuticals, why pay for a high-priced drug benefit?" But what happens if you suddenly need a costly long-term drug? Many policies allow you to upgrade to a plan with better benefits, after a six-month waiting period. You might also check out WalMart. The company recently started a program in 27 states to fill 30-day generic prescriptions for just $4 each. Nearly 300 drugs are covered. Among them are clonidine (blood pressure), metformin (diabetes) and fluoxetine (an antidepressant). HSA deposits roll over year to year, so you don't lose the money if you stay healthy. Withdrawals to pay for medical expenses are never taxed or penalized as long as you live. After age 65, you can withdraw the money for any reason without penalty, but you'll have to pay taxes if the withdrawal is for nonmedical expenses.Eat Healthy, Pay Less The best way to cut your food bill is to eat less. Seems obvious, but here's something you probably didn't know: Researchers at the University of Wisconsin-Madison calculated that while "supersizing" your fast-food meal might be penny-wise (the average supersize adds just 17 percent to the price but 73 percent more calories), it's literally pound-foolish. Dave Lieberman, chef and host of Good Deal With Dave Lieberman on the Food Network, throws cold water on the common belief that healthy food costs more than junk. And he dismisses the myth that coupons will save you money. Most coupons, he says, are designed to promote new, more expensive items. "I never use coupons unless it's for something I need".Drive a Good Bargain Gas goes up, gas goes down, but the long-term trend is going nowhere but up. Protect yourself by ditching that gas guzzler (原意：酒量大的人), but be careful. Many hybrids don't get much better mileage than smaller conventional cars, says Terry Savage, and they cost a lot more. Even hybrids with excellent mpg ratings save the most money in stop-and-go city traffic. "I considered buying a hybrid", says Savage, who takes public transportation in her hometown of Chicago and drives on weekends to get out of the city. "But most of my miles are on the highway. I figured out the difference in miles per gallon, and the extra cash outlay for the hybrid didn't make sense. But if you do a lot of city driving, it might be a good deal". The federal government is currently offering tax credits for buying new hybrids. The credit varies considerably depending on the car.Get a Handle on Home Energy You already know that by insulating and sealing up your house, you can save money on your heating and air-conditioning bills. But did you know those improvements can save you big tax dollars? Many energy-efficient upgrades you make on your home during the 2006/2007 calendar years qualify for a federal tax credit up to $500 over the two years. (Tax School 101: A tax credit means a dollar-for-dollar reduction on the taxes you owe; that's better than a tax deduction, which merely lessens the amount of income on which you are taxed.) Say you spend $ 600 adding extra insulation to your attic (the most common site of heat loss). You can subtract ten percent of that cost, or $60, from your tax bill. Energy Star-rated windows and doors (an efficiency standard set by the federal government) generally qualify for the credit, offsetting the higher cost of these products. But you won't get the credit if you don't claim it.Shop Smart Clothing's a basic need, but the endless cycle of sales, the proliferation of outlet stores, and online coupons can actually make people spend more on clothing than necessary, says Kathryn Finney, author of How to Be a Budget Fashionista. Instead of grabbing everything that catches your eye, apply Finney's "cost-per-wear" rule: "When I see something I like, I ask myself 'How many times am I going to wear this in a year?' Then I divide the price by that number. Ideally, an article of clothing should cost no more than $3 per wear". To help you find the best deals on the Internet, there's new bargain-tracking software that notifies you (your toolbar turns colors) when your favorite stuff is on sale. Check out the Intelligent Shopping toolbar at ShopAtHome. com. Finney also likes Wow-Coupons. corn for its printable coupons that she takes to the store. When you do go shopping, don't be afraid to ask your salesperson if she's got any coupons or deals. Or ask if that's her best price. Some stores will take off as much as 15 percent, just for the asking. To stick to her budget, Finney avoids credit cards and buys prepaid gift cards at her bank in the amount she can afford. "Once it's gone, it's gone", she says. The cards may cost a few dollars. Check for hidden fees and expiration dates.

They seldom killed the bison for meat. One famous 8 , however, Buffalo Bill Cody hunted buffalo for meat. The railroads used the meat to feed their workers 9 save money. As a result, many buffaloes were killed during that time. However, the American buffaloes were difficult to hunt because they could run at a speed at almost 75 kilometers an hour and were always 10 for a fight. There were times when five or six bullets would not kill them, and buffalo hunters sometimes had a lot of trouble killing this kind of animals. The buffaloes were hard to control and the hunters would get confused or feel helpless. Finally, in the West, the expression to buffalo, came to mean to make one helpless or to confuse and trick. It is still used today. When a person has you "buffaloed", he has you in his power. You"re helpless!
