The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audiences could see his hero and heroine in front of it at the end of the film as they said goodbye to each other forever. He sent his camera crew out one evening to film the sunset for him.

    The next morning he said to the men, “Have you provided me with that sunset?”

    “No, sir,” the men answered.

    The director was angry. “Why not?”  he asked.

    “Well, sir,” one of the men answered, “we're on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset.”

    “But I want a sunset!” the director shouted. “Go to the airport, take the next flight to the west coast, and get one.”

    But then a young secretary had an idea. “Why don't you photograph a sunrise,” she suggested, “and then play it backwards? Then it'll look like a sunset.”

    “That's a very good idea!” the director said. Then he turned to the camera crew and said, “Tomorrow morning I want you to get me a beautiful sunrise over the sea.”

    The camera crew went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay. Then at nine o'clock they took it to the director. “Here it is, sir,” they said, and gave it to him. He was very pleased.

    They all went into the studio. “All right,” the director explained, “now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the ‘sunset' behind them.”

    The “sunset” began, but after a quarter of a minute, the director suddenly put his face in his hands and shouted to the camera crew to stop.

    The birds in the film were flying backwards, and the waves on the sea were going away from the beach.

    We get it: You're tired. You're busy. And your shoes are away over there. Excuses are OK sometimes, but not every day—and especially not today. So put on your sneakers, get up off the couch, and let us kick your excuses to the curb (路边).

    “I…dislike…panting !”

    Being really out of breath may mean you're trying too much too soon, which will kill your confidence. But you don't have to be huffing and puffing to get a workout. Being active doesn't have to mean high-intensity. It's just about moving.

    “I hate exercise.”

    It may seem unbearable, but you just have to get started. Exercise releases endorphins (your brain's own feel-good chemicals), which can be habit-forming. What' s the best exercise? The one you'll do regularly. So you may hate running. Don't run! Ride your bike or just dance. Even cleaning your room is active. As long as you're moving and getting your blood pumping, it counts. So get creative.

    “I don't have time.”

    You may not have lots of time to spare when you're busy with schoolwork, but we bet you can find 10 minutes. Bonus: An activity break will send oxygen to your brain, making you super-alert and more creative too. Famous thinkers like Aristotle and Steve Jobs liked “walking meetings," and you can follow in their footsteps by moving around while you brainstorm about a tough task or memorize your English vocabulary.

    “I never see results!”

    Even if you train with the help of a professional, you won't see results right away. But you will feel them almost immediately. Don't focus on how your body looks—focus on how you feel. Keep a journal of when you exercise (or don't) and how you feel that day: Stressed? Focused? Tired? When you start noticing the amazing effects of exercise, you'll have no excuses.

    The Humane Society of Utah,a non-profit organization,is the largest shelter in the state because it takes every animal that can be lawfully accepted.The shelter employed photographer Guinevere Shuster,from New York,who came up with a creative way to find new homes for the dogs.She took lively photos for them.

The 31-year-old created sets of four pictures showing the playful and serious sides of each animal.Guinevere Shuster tried her best to show these dogs the way they'd really look if you allowed them into your life.She said,"I'm always trying to imagine better ways to make the poor animals attractive to the public.The photos show their great personalities and are a much better way than presenting them as the sad dogs waiting to be taken home.I'm lucky because I get to connect the two things I love most,animals and photography."

Guinevere says she finds it easy to work with dogs.She said,"It's just me and the dog in the office so they can pay their attention to the photo-taking.I use a lot of treats and some funny noises I've learned to get the dogs' attention. A fun method is to throw treats at the dogs-it's useful for getting unusual looks from them."

    Since starting the project,a number of dogs have been taken home by dog lovers after they saw Guinevere's pictures on the Humane Society of Utah's Facebook page.In the last three years,she has photographed more than 4,000 animals.This year,the shelter has placed nearly 9,000 homeless pets into their permanent homes.

    People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a similar problem. They often accept the opinions or ideas of other people. Other times they begin to act without thinking. They try to find a solution by trial and error. However, when all these methods fail, the person with a problem has to start analyzing. There are six stages in analyzing a problem.

    First the person must recognize that there is a problem. For example, Sam's bicycle is broken, and he cannot read it to class as he usually does. Sam must see that there is a problem with his bicycle.

    Next the thinker must define the problem. Before Sam can repair his bicycle, he must find the reason why it does not work. For instance, he must determine if the problem is with the gears, the brakes, or the frame. He must make his problem more specific.

    Now the person must look for information that will make the problem clearer and lead to possible solutions. For instance, suppose Sam decided that his bike does not work because there is something wrong with the gear wheels. At this time, he can look in his bicycle repair book and read about gears. He can talk to his friends at the bike shop. He can look at his gears carefully.

    After studying the problem, the person should have several suggestions for a possible solution. Take Sam as an illustration. His suggestions might be: put oil on the gear wheels; buy new gear wheels and replace the old ones; tighten or loosen the gear wheels.

    Eventually one suggestion seems to be the solution to the problem. Sometimes the final idea comes very suddenly because the thinker suddenly sees something new or sees something in a new way. Sam, for example, suddenly sees that there is a piece of chewing gum between the gear wheels. He immediately realizes the solution to his problem: he must clean the gear wheels.

    Finally the solution is tested. Sam cleans the gear wheels and finds that afterwards his bicycle works perfectly. In short, he has solved the problem.

    If you ask people to name the one person who had the greatest effect on the English language, you will get answers like "Shakespeare," "Samuel Johnson," and "Webster," but none of these men had any effect at all compared to a man who didn't even speak English-William the Conqueror.

    Before 1066, in the land we now call Great Britain lived peoples belonging to two major language groups. In the west-central region lived the Welsh, who spoke a Celtic language, and in the north lived the Scots, whose language, though not the same as Welsh, was also Celtic. In the rest of the country lived the Saxons, actually a mixture of Anglos, Saxons, and other Germanic and Nordic peoples, who spoke what we now call Anglo-Saxon (or Old English), a Germanic language. If this state of affairs had lasted, English today would be close to German.

    But this state of affairs did not last. In 1066 the Normans led by William defeated the Saxons and began their rule over England. For about a century, French became the official language of England while Old English became the language of peasants. As a result, English words of politics and the law come from French rather than German. In some cases, modem English even shows a distinction(区别)between upper-class French and lower-class Anglo-Saxon in its words. We even have different words for some foods, meat in particular, depending on whether it is still out in the fields or at home ready to be cooked, which shows the fact that the Saxon peasants were doing the farming, while the upper-class Normans were doing most of the eating.

    When Americans visit Europe for the first time, they usually find Germany more "foreign" than France because the German they see on signs and advertisements seems much more different from English than French does. Few realize that the English language is actually Germanic in its beginning and that the French influences are all the result of one man's ambition.

A huge lake of salty water appears to be buried deep in Mars, scientists reported this week. The presence of water raises the chances of finding life on the red planet. The discovery is based on observations by a European spacecraft. It has excited experts. Water is necessary for life, and scientists have long hoped to prove that it is present on Mars.

Cassie Stuurman is a geophysicist at the University of Texas. In 2016, she found evidence of a huge ice deposit(沉积)on Mars. “If these researchers are right, this is the first time we've found evidence of a large water body on Mars. ”Stuurman said. Researchers are not yet sure how deep the area of water is. So, they cannot say whether it is an underground pool, or just an area of soft and wet soil.

In order to find the water, Italian researchers examined radar signals. The signals were collected over three years by the European Space Agency's Mars Express spacecraft. The results suggest that a 20-kilometer-wide water body lies below ice that is 1.5 kilometers thick. They believe the area is close to the planet's southern pole.

    Mars is very cold, but salt in the water may have kept it from freezing. It is the same as when you put salt on a road to prevent ice from forming. The water would be extremely cold, right at the point where it's about to freeze. And it would be salty. Such conditions are not ideal for life to form. But, she said there are bacteria on the earth that have been able to survive in similar conditions.

Mars has been a popular planet for exploration, with some groups placing instruments on its surface and others examining it from space. In May, NASA launched another spacecraft, the InSight Mars lander which will dig deep into the data under the surface after it reaches a flat area of the planet in November.
