Sports account for a growing amount of income made on the sales of commercial time by television companies. Many television companies have used sports to attract viewers from particular sections of the general public, and then they have sold audiences to advertisers.

An attraction of sport programs for the major U. S. media companies is that events are often held on Saturday and Sunday afternoons—the slowest time periods of the week for general television viewing.  Sport events are the most popular weekend programs, especially among male viewers who may not watch much television at other times during the week. This means the television networks are able to sell advertising time at relatively high prices during what normally would be dead time for programming.

Media corporations also use sports to attract commercial sponsors that might take their advertising dollars elsewhere if television stations did not report certain sports. The people in the advertising departments of major corporations realize that sports attract male viewers. They also realize that most business travelers are men and that many men make family decisions on the purchases of computers, cars and life insurance.

Golf and tennis are special cases for television programming. These sports attract few viewers, and the ratings(收视率)are unusually low. However, the audience for these sports is attractive to certain advertisers. It is made up of people from the highest income groups in the United States, to certain advertisers. It is made up of people from the highest income groups in the United States, including many lawyers and business managers. This is why television reporting of golf and tennis is sponsored by companies selling high-priced cars, business and personal computer, and holiday trips. This is also why the networks continue to carry these programs regardless of low ratings. Advertisers are willing to pay high fees to reach high-income consumers and those managers who make decisions to buy thousands of “company cars” and computer, with such viewers, these programs don’t need high ratings to stay on the air.

Many of you should not own dogs. It’s that simple. The reason is that, if you own a dog, you must train a dog, and many dog owners out there, it is safe to say, have little or no control over their dogs, because they do not train them.

Strong words? Maybe．But they are simple, honest words, as untrained dogs living in residential neighborhoods bark at will, run loose, and visit and damage neighboring properties with their owners’ blessings as they let them run on purpose.

Take note of the fact that you, the dog owner, cannot control your dog causing a continual nuisance（麻烦事）that damages the quality of life in your neighborhood. There’s nothing more annoying to most people than a dog that barks and nothing more confusing than trying to understand the deficient（有缺陷的）mentality of the dog owner who allows his dog to do so.

After all, the irresponsible dog owner hears the barking too, and so those who must put up with it are continually left wondering-what are they thinking, are they deaf?

Many dog owners believe it is not possible for their dog to be trained, an indication that the owners themselves lack self discipline, and most likely have never really tried to apply discipline to other issues in their lives, not with consistency, or that they are simply lazy and inattentive(疏忽的) to their own adult responsibilities at the expense of others.

Irresponsible dog owners, though, do train their dogs. A dog is a reflection of its owner. Whatever a dog does (run loose, bark at will, jump on guests entering the front door, soil neighboring lawns) is a result of the decisions of the owner. The choice not to do something is indeed a choice.

The good news is that with mere consistency(一致性), a dog can be trained rather quickly, in a couple of weeks if the owner takes his responsibility seriously. Again, that process will be a reflection of the ownerˈs behavior, and the primary ingredient（要素）in that behavior is not allowing the dog, not even once, to repeat the bad behavior without consequences when told and directed not to. You can stop your dog from barking with simple firm voice commands, direct eye contact, and force of will in a relatively short time, as long as you are consistent and a reasonably mature person.

Dogs, what’s more, love this training because pleasing you, their owner, is what they are all about. The upshot（结果，要点）will be that you have a more connected relationship you’re your dog, a better dog that is suitable for its environment.

Do you really know who you are? This is not a trick question but rather an honest understanding into the inner workings of each one of us. We usually share with our friends a piece of who we are, the piece that we want them to like or connect with. However, there is a secret, a hidden piece that doesn’t want to be noticed by others.

Our personal inner beliefs play a vital role in the way we think, act and live. They set us up to accept a belief and then it is the belief that separates our personal story. There are numerous people who have taken on the pain and suffering of their parents. Some have devoted their lives to living with lack; that is lack of love because they saw what they thought was love while in the crib(婴儿床) and it frightened them. Subconsciously(潜意识地) they made great efforts in their lives to avoid a similar experience.

Each one of us carries around with us our inner beliefs. If one of your beliefs is one that causes you to hold back from getting the perfect job or blocking love to come to you, that belief is a negative belief and one that needs to be dealt with if you are seeking a life of joy, contentment and personal success, whether it is emotional, spiritual, financial or physical.

Do not let your blocked or frozen emotions guide the way you want to lead your life. Now it is your time to finally become victorious over those past situations that have upset you during your entire life and become the winner you were born to be.

The Masai are a people who are constantly trying to preserve their own ways in an increasingly modem world. They live along the border of Kenya and Tanzania, moving their homes from time to time to follow their cattle, the source of their living.

The Masai have become known as a people of fighters, protecting their cattle against lions and other enemies. Only men are fighters. They wear long hair, which is colored red with clay. They can have more than one wife. Women build and take care of the home, fixing food and making clothing. Women and children keep their heads shaved. Women can also become elders, once they have given birth to four healthy children.

The Masai depend on their cattle for many parts of their life. They drink cow's milk and blood as a sacred drink. They use the cows' waste to cover and seal their homes. They don't kill their cattle for food, but if a cow is killed, then the horns (角) are used for containers; the hides are used to make shoes, clothing, ropes and bed coverings; and the bones are made into decorations.

The more cattle a man owns, the richer he is considered to be. A man who owns 50 or fewer cattle is considered poor. A "rich" man has a thousand or more. The cattle, though owned by the man, are considered to belong to the man's entire family. The family names the cattle and can recognize each animal's unique voice.

Masai houses are made from sticks and grass, but they are meant to be temporary, since the move of their cattle means that the Masai move as well.

In a video posted online, a United Airlines passenger, who is an Asian, is shown with a bloody face after he was forced off an overbooked flight on April 9, 2017, making the already troubled airline earn more bad press.

Overbooking on flights happens all the time. Empty seats cost airlines money, so they offset(抵消) the number of passengers who miss flights by selling several more tickets. In this case, the problem arose because United (美联航) decided at the last minute to fly four employees to a connection point and needed four passengers to make way for them.

Normally, when there's an overbooking issue, airlines will offer compensation to the passengers who are willing to take a later flight. At first, they were offered $400, a hotel room for the night, and a flight the following afternoon. When no one took the offer, the amount was upped to $800. Still no volunteers. So a manager boarded the flight and informed passengers that four people would be selected to leave the flight.

A couple who were selected agreed to leave the plane voluntarily. However, A man refused, saying he was a doctor and had to see patients in the morning. An airline manager told him that security would be called if he did not leave. Then, security officers came to speak to him. Their conversation ended with the man being yanked (猛拉) from his seat onto the floor and dragged off, blood visible on his face.

This incident caused a stir in public. Many criticized United's racism and cruelty. Some even called for a boycott of the airline. The company is facing increasing pressure around the world. United is also suffering from broader worries among investors about US airline performance.

Who knows about sleep? Astronauts. They have to. Their bodies are cut off from the outside world that reminds us what time it is. But actually, it’s even worse than that. An astronaut reported in his diary that he was likely to make mistakes on days following an unusually late bedtime.

So NASA started doing some serious research. They quickly realized that we’re a slave to the outside world. Without light and darkness, we’re unable to regulate (管理) sleep times.

Because of modern technology, we’re all living more like astronauts now. Light is no longer a function of the sun, but of always-on indoor lights, TV and computer screens. Temperature no longer follows a cycle of cooling at night and warming during the day. Is it any wonder that a third of American have sleep problems?

Maybe you think this doesn’t affect you--- or at least not much. You’re wrong. Research done on non-astronauts has shown the same thing. After two weeks of six hours of sleep a night, you’re drunk. By the end of two weeks, the six-hour sleepers behaved as badly as those who hadn’t slept for 24 hours.

But what did they say when asked how they felt? “It’s not affecting me.” So if you are performing poorly because of sleep problems, you may have no idea. This is a real problem.

So what answers did NASA come up with?

Take an hour to calm down before bed. Yes, you’re busy. But your time is not more valuable than an astronauts’.

Keep your bedroom dark, cool and free from noise. Even if you think “the light doesn’t affect you” or “the noise isn’t that bad”, it can still affect sleep quality.

Another advice: forget the alarm clock in the morning; set an alarm to remind you to go to bed at night. When it goes off, finish up any work on the computer, and turn off any unnecessary lights. This prevents you from cheating yourself on sleep and allows you to wake up naturally.
