[Q]: Article: Several years ago I worked in an office, which had a locust tree growing outside the window. It had grown into a tall tree and must have been there for a long time. The tree blocked the view and made the office seem dull, unfortunately this happened to be the room assigned to me and I was depressed by it for quite some time. When the first spring came, everything was green except the locust tree. Secretly, I was very happy because I had thought it had died. One morning when I opened the window for fresh air, I unexpectedly smelt a familiar sweet scent floating into my office but I couldn't name it. Suddenly, I realized it was the locust tree! The tree that I thought dead was blossoming in full glory. From then on, I usually came to the office very early to see dew forming on the locust tree blossoms and every year was eager to see spring again. During summer, the green leaves provided shade protecting me from the harsh sunlight, but allowing enough light in to make it pleasant. In autumn, the leaves turned into many different color1s. Its beauty touched my soul. Many times I thought to take photos but never did. Then I had to leave in a hurry. Later in life it became a great regret that I had not done so. Actually, many times in our lives, we think we own something, therefore we don't cherish it. We don't feel regretful until we lose it one day! Moreover, sometimes, we have to accept the things we don't want and need to discover the hidden beauty to find unexpected joy!

[Q]: Article: Many people say dolphins are very intelligent. They seem to be able think, understand, and learn things quickly. But they are smart like humans or more like cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are alike in some ways. How? FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins? Why do they assist the men? The dolphins get to eat some of the fish.

[Q]: Article: You and your friends are settling into your seats. The new Spider- Man movie is about to start and you've got the snacks: soda and popcorn. Food is part of what makes the movie fun. Just as the lights go out, you catch a slight smell of ...tuna fish?! You turn your head, searching for the source. Then you spot him: A couple rows back, some guy is enjoying a tuna fish sandwich. How's he get that in here? You wonder. Then you remember how much you paid for your snacks. What invites the unwelcome outside food is probably the price. Why pay $5 for a bag of M&Ms when you can get them for a dollar at the corner store? Earlier this year, a Michigan man decided to fight for his right to snack. Joshua Thompson is suing his local theatre after it banned outside food. He argues the ban breaks a Michigan law that prevents business from charging extremely high prices. However, most legal experts believe Thompson has little chance of winning his case though he does have a point: 85 percents out of every dollar of treats a movie theatre sells is pure profit . The truth is that movie theatres are more in the snack business than the movie business. A huge part of the ticket income goes to the Hollywood studio. This makes sense, since the studio have to pay the costs of movie production and advertising. But that often doesn't leave much cash for the theater, which also has its own running costs. If customers stopped buying food, owners would have to raise ticket prices even higher. Of course, there's another reason to think twice before bringing food into the movies: It's against the rules. Breaking those rules can be unpleasant consequences, too. Some theatres will kick you out if they catch you. Even without the threat of punishment, we should follow rules all the time-----out of respect. Here's a good idea: Eat before the movie.
