The Owl Count

    Annie slept in the front of the seat with her father drovethrough the darkness. “We're almost there!” Dad announced cheerfully. “Soon we'll be observing and counting owls at the state park.” Yawning, Annie noddedand smiled. The time was 4:30 a.m. Looking out into the darkness, Annie remembered learning in school that most owls are active at night, when they hunt for food. During the day they sleep in hard-to-find spots.

    “Dad, why do you need to count owls?” she asked. “It's importantfor the scientists to have current information about bird populations,” he explained. “We want to know which birds have decreased in number and whether any new kinds of birds are coming into a certain area. You and I will write down the kinds of birds that we see today and keep a record of how many times we see each kind. Then we'll send out a report to a scientific organization that is collecting about birds from people all over the country.”

    Dad pulled into the parking lot of the state park. Then, with flashing in hand, they began their hike into the woods. Annie zipped up hercoat and tried to keep from trembling. She had not expected the morning to beso cold. Luckily her gloves were in her pocket.

    Suddenly Annie's father stopped and gestured for her to bestill. Obeying, Annie did not take another step. She thought she heard a low crying up head. “That's certainly a screech owl,” her father whispered. “Let's get a look at it.” After looking more closely, Annie could see that it was asmall owl. Sensing danger, the owl narrowed its eyes and pulled its feathers tightly against its body. Annie carefully wrote down in her notebook that theyhad seen a screech owl.

    Walking a little farther, they came to a tall oak tree. “Thislooks like a perfect spot to attract owls,” Dad said, “I'm going to play a recording of common call of the barred owl. Maybe we can get one to answer." Annie could hardly believe her ear. The recorded call sounded as if the birdwere asking, “Who cooks for you?” Moments later Annie thought she heard areturn call in the distance. She held her breath and waited. Suddenly a huge bird landed very quietly on a branch above them.

    Annie had long forgotten how cold it was. She stood in wonder, shining her flashlight on the bird and studying it carefully. The barred owl was nearly two feet tall. Grey feathers surrounded its dark eyes. The bird did not stay long, but it did not matter. Annie would never forget the image of the powerful barred owl.

    Cleaning your plate may not help feed hungry children today, but the timeworn advice of mothers everywhere may help reduce food waste from the farm to the fork, help the environment and make it easier to feed the world's growing population.

    Hard data still being collected, but experts in Chicago said about 30% to 50% of the food produced in the world goes uneaten. The average American throws away 33 pounds of food each month—about $40 worth, which means each person throws away almost 400 pounds of food. The US Department of Agriculture says that 23% of eggs and an even higher percentage of produce ends up in the trash.

"We forget we have all these fresh fruits and vegetables, and at the end of the week we have to throw them away", said Esther Gove, a mother of three young children in South Berwick, Maine. "Now, I don't buy as much fresh produce as I used to."

    But the effect of food waste arrives far beyond the kitchen. Agriculture is the world's largest user of water, a big consumer of energy and major emitter of greenhouse gases during production. Experts say reducing waste is a simple way to cut stress on the environment and can ease pressure on farmers, who will be called on to feed an expected 9 billion people around the world in 2050, compared with nearly 7 billion today.

    No matter how sustainable (可持续的) farming is, if the food's not getting eaten, it's not sustainable and it's not a good use of our resources. In richer nations, fruit and vegetables end up in the trash because they aren't pretty enough to meet companies' standards, have gone bad in a home refrigerator or aren't eaten at a restaurant. In developing countries, much food spoils before it gets to market due to poor roads and lack of refrigeration. High food prices are another reason, since some people can't afford the food that's produced.

    On a clear night, you can see a sky paced with stars. But you can't see planets orbiting any of these stars, even with the strongest Earth—based telescopes. Astronomers reported that they discovered seven Earth—sized planets orbiting a nearby star called TRAPPIST – 1 in February. They had to rely on indirect evidence to tell them that the planets are there. By doing some math, they figured out the number of planets and the distance of their orbits.

    TRAPPIST – 1 is a red dwarf （红矮星）, much smaller than our sun, but larger than Jupiter (木星). If the sun were the size of a basketball, TRAPPIST – 1would be the size of a gold ball. This star is one of our closest neighbors, just like the moon to the earth in space.

    When astronomers using Earth-based telescopes to study TRAPPIST – 1,they noticed that every once in a while, it became slightly dim（昏暗）. They decided that a planet must be passing in front of the star, blocking part of the light. This dimming would come and go as the planet orbited the star, passing alternately (交替地) behind and in front of the star regularly.

    By making careful observations, astronomers expected to get a rough idea of the planet's size from the pattern of dimming light. But the light level changed often and not at evenly spaced (均匀间隔的) times. The astronomers had to conclude they were looking at more than one planet! To get additional data, NASA's spritzer Space Telescope measured TRAPPIST –1's brightness nearly continuously for 20 days, catching 34 crossings of planets in front of the star. Sorting through the mess of data, the astronomers found that the innermost planet completes its orbit in 1.5 Earth days, while the outermost planet takes 20 days. Once you know how long it takes each planet to complete an orbit, you can work out how far it is from the star compared with the other planets.

    The TRAPPIST – 1 planets are not alone. So far, astronomers have found more than 3,400 planets that orbit other stars.

    We can make mistakes at any age. Some mistakes we make are about money. But most mistakes are about people. Did Jerry really care when I broke up with Helen? When I got that great job, did Jim really feel good about it, as a friend? Or did he envy my luck? And Paul-why didn't pick up that he was friendly just because I had a car? When we look back, doubts like these can make us feel bad. But when we look back, it's too late.

    Why do we go wrong about our friends or our enemies? Sometimes what people say hides their real meaning. And if we don't really listen we miss the feeling behind the words. Suppose someone tells you. You're a lucky dog. That's being friendly. But lucky dog? There's a bit of envy in those words. Maybe he doesn't see it himself. But bringing in the dog bit puts you down a little. What he may be saying is that doesn't think you deserve your luck.

    Just think of all the things you have to be thankful for another noise that says one thing and means another. It could mean that the speaker is trying to get you to see your problem as part of your life as a whole. But is he? Wrapped up in this phrase is the thought that your problem isn't important. It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night.

    How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking. Do his words fit the way he looks? Does what he says agree with the tone of voice? His posture（姿态）? The look in his eyes? Stop and think. The minute you spend thinking about the real meaning of what people to you may save another mistake.

    A strange object was found in a small city called Carlos Spegazzini, just a short drive from the capital city of Buenos Aires.

    When farmer Jose first found an odd scene in his farmland, he began to dig at the object. However, he quickly found himself running to tell his wife. Jose needed more support if he was going to investigate this strange thing.

    Even the dog was hesitant to investigate. Unfamiliar with the object, man's best friend was not about to jump at it with little concern. Therefore, they chose to call in somebody who has a better idea of what to do.

    When the police first showed up, they were just as stumped as Jose. They knew this object was something out of the ordinary. It might even be something extraordinary, so more questions appeared.

    It quickly became apparent, it was time to call in the big guys. That's right; when you find something that appears to be out-of-this-world, it's time to call in those who study the mysteries of the old world.

    Authorities called in archaeologists who jumped at the chance to study the object. They quickly determined one thing was for certain: the ancient big one that left this behind was absolutely massive! The group was unable to move the shell, as it weighed nearly two tons!

    Clearly, this massive beast was not the only of its kind existing in the modem-day world. Similar fossils had been found in the surrounding areas and had even made their way to museums. But what was the ancient beast?

    The theatre in Shakespeare's time was much different than it is today. Authors wrote plays for the masses, especially those who couldn't read or write.

    The theatre changed a lot during Shakespeare's lifetime. The authorities didn't like it and didn't allow acting in the city itself: They thought it had a bad influence on people and kept them from going to church. Queen Elizabeth, on the other hand, loved acting and helped the theatre become popular.

    The theatre in Shakespeare's time was full of life. People did not sit all the time and it was not quiet during the performance. The audience could walk around, eat and drink during the play.

    Theaters were open arenas or playhouses that had room for up to three thousand people. There was almost no scenery because the dialogue was the most important part of the play. Colourful and well-designed costumes were very important and told the people about the status of a character. Women never performed in plays, 80 young boys played female characters. The performances took place in the afternoon because it was too dark at night.

    There was no stage crew as there is today. Actors had to do everything themselves-from making costumes to setting the stage. Plays were organized by acting companies. They performed about 6 different plays each week because they needed money to survive. They had almost no time to rehearse (排练).

    The companies in Shakespeare's time had a rank system. The company belonged to shareholders and managers. They were responsible for everything and got most of the money when the company was successful. Sometimes they even owned their own buildings. Actors worked for the managers and after some time became a permanent member of the company. Apprentices (学徒) were young boys and were allowed to act in unimportant role. They also played female characters in plays.
