1 . Everyone knows that taxation is necessary in a modern state: without it , it would not be possible to pay the soldiers and policemen who protect us; _____ the workers in government offices who   _____ our health, our food, our water, and all the other things that we cannot do for ourselves. _____ taxation, we pay for things that we need just as much as we need somewhere to live and something to eat.

_______ everyone knows that taxation is necessary, different people have different ideas about ________ taxation should be arranged.

In most countries, a direct tax on _____, which is called income tax, exists. It is arranged in such a ______ that the poorest people pay nothing, and the percentage of tax grows ______ as the taxpayer’s income grows. In some countries, for example, the tax on the richest people goes up as high as ninety-five per cent!

And countries with taxation nearly ____ have indirect taxation too. Many things imported into the country have to pay taxes or “duties” Of course, it is the men and women who buy these imported things in the shops _____. really have to pay the duties, in the ______ of higher prices. In some countries, ______, there is a tax on things sold in the shops. If the most necessary things are taxed, a lot of money is ______ but the poor people suffer most. If unnecessary things ______ jewels and fur coats are taxed, less money is obtained but the tax is _______ as the rich pay it.

Probably this last kind of indirect tax, together with a direct tax on incomes which is low for the poor and high for the rich, is the best arrangement.

2 . The modern Olympic Games, founded in 1896, began as contests between individuals, rather than among nations, with the hope of promoting world peace through sportsmanship. In the beginning, the games were open only to _______. An amateur is a person whose involvement in an activity - from sports to science or the arts - is purely for ________. Amateurs, whatever their contributions to a field, expect to receive no form of compensation; professionals, ________, perform their work in order to earn a living.

From the perspective of many athletes, ________, the Olympic playing field has been far from fair. Restricting the Olympics to amateurs has excluded the participation of many who could not afford to be _______. Countries have always desired to send their best athletes, not their ________ ones, to the Olympic Games.

A slender and imprecise line separates what we call “financial support” from “earning money.” Do athletes “earn money” if they are reimbursed for travel expenses? What if they are paid for time lost at work or if they accept free clothing from a manufacturer or if they teach sports for a living? The runner Eric Liddell was the son of poor missionaries; in 1924 the British Olympic Committee ________ his trip to the Olympics, where he won a gold and a bronze medal. College scholarships and support from the United States Olympic Committee made it possible for American track stars Jesse Owens and Wilma Rudolph and speed skater Dan Jansen to train and compete. When the Soviet Union and its allies joined the games in 1952, the ________ of amateur became still less clear. Their athletes did not have to ________ work and training because as citizens in communist regimes, their government financial support was not considered payment for jobs.

In 1971 the International Olympic Committee (IOC) ________ the word amateur from the rules, making it easier for athletes to find the ________ necessary to train and compete. In 1986, the IOC allowed professional athletes into the games.

There are those who ________ the disappearance of amateurism from the Olympic Games. For them the games ________ something special when they became just another way for athletes to earn money. Others say that the designation(命名) of amateurism was always ________; they argue that all competitors receive so much financial support as to make them paid professionals. Most agree, however, that the ________ over what constitutes(组成) an amateur will continue for a long time.

3 . In 1965, 17-year-old high school student Randy Gardner stayed awake for 264 hours to see how he’d cope without sleep. On the second day, his eyes stopped focusing. Next, he lost the ability to ________ objects by touch. By day three, Gardner was moody and uncoordinated. At the end of the experiment, he was ________ to concentrate, had trouble with short-term memory and started hallucinating(出现幻觉). Although Gardner recovered without long-term psychological or physical ________, for others, sleeplessness can result in hormone(激素) imbalance, illness, and even death.

Sleep is ________. Adults need 7 to 8 hours of sleep at night, and adolescents need about 10. In the United States, it's estimated that 30% of adults and 66% of adolescents are ________ sleep deprived. When we lose sleep, learning, memory, mood, and reaction time are affected. Sleeplessness may also cause inflammation, hallucinations, high blood pressure, and it's even been ________ to diabetes and obesity.

How can sleep ________ cause such enormous suffering? Scientists think the answer lies with the ________ of waste products in the brain. During our waking hours, our cells are busy using up our day's energy sources with get broken down into various by-products, including adenosine(腺苷酸). As adenosine builds up, it increases the ________ to sleep, also known as sleep pressure. In fact, caffeine works by ________ adenosine's receptor pathways. Other waste products also build up in the brain, and if they're not cleared away, they collectively ________ the brain and are thought to lead to the many negative symptoms of sleep deprivation.

So, what's happening in our brain when we sleep, to prevent this? Scientists found something called the Lymphatic System, a clean-up mechanism(机能) that removes this build up and is much more ________ when we're asleep. It works by using cerebrospinal fluid(脑脊髓液) to flush away toxic by-products that accumulate between cells. Lymphatic vessels, which ________ pathways for immune cells have recently been discovered in the brain, and they may also play a role in ________ the brain's daily waste products. While scientists continue exploring the restorative mechanisms behind sleep, we can be sure that sleeping is a(n) ________ if we want to maintain our health and our sanity.

4 . A true reality of retirement planning is that your future is riding on the quality of your assumptions. Humble ______ can be dangerous.

For example, eight years into this bull market, expecting stocks to deliver as strong returns over the next decade is an uncertain proposition many are nonetheless ______.

Another potential ______ assumption is that you will be able to keep working past 65. Yet the recently released 2017 Retirement Confidence Survey by the nonpartisan Employee Benefit Research Institute finds that more than half of workers say they expect to still be on the clock past age 65. ______, less than 15 percent of today's retirees kept working that long.

"If you plan on working longer as a way to get by in retirement, you are going to be in trouble," says Craig Copeland, senior research associate at EBRI. "It should be a ______ to a solid savings and spending plan, not the foundation."

It's simply too ______ to assume you will indeed be able to work longer. A survey by the Transamerica Center for Retirement Studies found that nearly two-thirds of retirees left the workforce earlier than expected because they were laid off, reorganized out of a position, or due to general unhappiness with a job. Only 16 percent of retirees who ______ the work force earlier than they expected did so because they felt they could ______ afford to.

______, a new report from Prudential puts a dollar value on why your current employer may not be inclined (倾向于) to do back flips to keep an older you happy and engaged. The estimated one-year cost to a firm when an employee ______ retirement: $50,000.

Prudential estimates that on a company-wide level, delayed retirement can ______   overall workforce costs by 1 percent to 1.5 percent. That's not nothing. And it goes a long way in explaining why employers may be more inclined to focus on "financial wellness" strategies to get workers ready to retire ______ than programs to help workers delay retirement.

Fewer than one-third of employees surveyed by TCRS report their employer has some sort of "transition" program such as flexible work schedules, reduced hours or ______ to a different role.

"Workers' vision of retirement is changing faster than employers' business ______," said Catherine Collinson, president of TCRS. That makes it ever more crucial for pre-retirees to take the steps today that will increase the ______ they can continue to work longer, if that's part of the plan.

It was all worth it. The look on their faces as we ____ in Rovaniemi, Finland, was ____. Four days of total magic followed. We took sleigh rides, ____ snow mobiles (雪地摩托) and patted reindeer. On our fourth day we finally ‘found’ Santa, who had a genuine, thick white ____. His home was ____ from floor to ceiling with Christmas parcels, which was every child’s dream.

If that wasn’t ____, he held four hand-written letters that our children immediately ____.

9 . Several years ago I started riding a bike. At first, I thought it was only a ______ ride. But as I built up strength, my friends encouraged me to try some longer ______. The first one to come along was a 150-mile journey, an event held every year that ______ money to fight cancer.

When I signed my name, the ______ seemed great — to support a worthy cause while going for the ______ — and I trained with great excitement. But as the time for the ride approached, my ______ gained ground over my endurance(耐力). I didn't really want to ______ all those miles for two days straight.

The ride began on a Sunday morning in the Georgia countryside, ______ for the first few hours I felt wonderful. This was just the ______ I had imagined, and my spirits were ______. But by the end of the day, I felt tired. I was sure I'd have to ______.

As I topped the hill, the nice sunset ______ me going for a few minutes more. Then in the distance, I ______ a lone rider riding very slowly.

My focus ______ at that moment. I'd been doubting my body for a whole day. But now I knew — it wasn't the body, but the ______ that would help me reach my goal.
