Whether you love happy endings or a dark reality in TV dramas,you could soon be able to decide what you get. Netflix,the TV-streaming company behind hit shows such as The Crown and House Of Cards,is working on ways to give viewers control of key plot decisions.

    Some of the storylines will be simple and linear,like the Choose Your Own Adventure books that many grew up with.For example,viewers might decide whether a prisoner in the drama Orange Is The New Black joins a gang (黑帮) or not.

    The technology could also potentially be used to allow Princess Margaret to marry Peter Townsend in The Crown,instead of having her relationship with the divorcee (离婚者) blocked by the Establishment.Other storylines will be much more complex,allowing viewers to connect plot points in a variety of ways using their TV remotes.

    A source said,"We're doing work on branch narratives (叙事) so you are actually making choices as you watch. All the content will be there,and then people will have to get through it in different ways.We'll see how it plays out. It's an experiment.We'll see if it gets much success.For creators,it's a new field."

    Actors would film numerous alternate plot segments (片段) in advance,letting viewers choose which route to take through the story.Netflix will run a trial with choose-your-own-adventure shows for children later this year, based on an established character.If they are successful,it will use the format for TV programmes aimed at adults. Netflix president Reed Hastings confirmed that the company is working on interactive shows,saying,"Once you have got interactivity,you can try anything."

    At least five million UK households are thought to be signed up to Netflix,and it is challenging traditional broadcasters.Earlier this year,BBC boss Lord Hall promised to reinvent the iPlayer so that it overtakes Netflix as a destination in its own right,rather than a catch-up service.

    NBA basketball players devote much of their lives to preparing for games. This preparation, which includes studying game films, practicing skills and treating injuries, is essential because of the pressure-packed nature of their profession.

    Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

    UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition (营养) “depending on who needs it”.

    Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.

    Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the whole forest.

    “We didn't take any notice of it.” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

    Abraham Lincoln, a self-taught lawyer, was elected 16th president of the United States in November 1860, shortly before the outbreak of the Civil War. Lincoln proved to be a smart military strategist and a competent leader: His Emancipation Proclamation (解放宣言) paved the way for slavery's abolition, while his Gettysburg Address stands as one of the most famous speeches in American history. In April 1865, with the Union on the brink of victory, Abraham Lincoln was killed; his untimely death made him a hero to the cause of liberty, and he is widely regarded as one of the greatest presidents in U.S. history.

    On January 20, 1981, Reagan took office. Only 69 days later he was shot by a would-be killer, but quickly recovered and returned to duty. His grace and wit during the dangerous incident caused his popularity to soar.

    At the end of his two terms in office, Ronald Reagan viewed with satisfaction the achievements of his innovative program known as the Reagan Revolution, which aimed to motivate the American people and reduce their reliance upon Government. He felt he had fulfilled his campaign pledge of 1980 to restore "the great, confident roar of American progress and growth and optimism."

    When George W. Bush, at the age of 54, became the 43rd president of the United States, it was only the second time in American history that a president's son went on to the White House. John Quincy Adams, elected the sixth president in 1824, was the son of John Adams, the second president. While John Adams had brought up his son to be president. George Bush, the 41st president, insisted he was surprised when the eldest of his six children became interested in politics, became governor of Texas, and then went on to the white House.

    Barack Obama served as the 44th President of the United States. His story is the American story—values from the heartland, a middle-class upbringing in a strong family, hard work and education as the means of getting ahead, and the belief that a life so blessed should be lived in service to others.

    With a father from Kenva and a mother from Kansas, President Obama was born in Hawaii on August 4, 1961. He was raised with help from his grandfather, who served in Patton's army, and his grandmother, who worked her way up from the secretarial pool to middle management at a bank.

    You may think there are no differences between British and American people. After all, they speak the same language, don't they? If you ask a British or an American person, he will probably tell you that there are differences. And the differences are quite great.

    What do British people think American people are like? The British think American people are very strange. They make a lot of noise and they laugh too loudly. They are rich, and they only think about money. But the British do say that American people are kind, and friendly people. They're happy to help you if you are in trouble.

    What do Americans think of the British? Well, they think the British are cold and very unfriendly. They are not interested in success or in making lots of money. They think British is the best country in the world. They look down on other countries. But Americans say that the British are quite hard workers. They are brave and honest. And in time of trouble they face difficulties happily.

    You can see that these ideas can cause misunderstanding between the British and Americans. But when American and British people become friends, they usually find things are not as bad as they expected.

    Most of the time, people wear hats to protect themselves from harsh weather conditions. Hats are also worn to show politeness and as signs of social position. But nowadays, hats, especially women's hats, are much more than that. More exactly, hats have changed into fashion and style symbols by many movie stars. What's more, people now consider many different features when choosing even a simple hat. Many designers point out that, when choosing the right hat, it's important to consider the color of your skin as well as your hair, your height, and the shape of your face.

    First of all, the color of the hat should match the color of your skin and hair. For instance, black hats should be avoided if you are dark skinned. If a purple hat is placed on top of red hair, one will look as attractive as a summer flower. Second, the height of the hat is also an important point. Tall women should not go for hats with tall crowns, just as short women should choose hats with upturned brims to give the look of height. Third, and most importantly, the shape of the face decides the kind of hat one should pick. A small, gentle hat that fits the head looks good on a small face. However, women with big, round faces should choose a different style.

As the saying goes, "Fine feathers make fine birds." A good hat can not only help your dress but also support your features, so why not choose the best possible one next time you want to be in public?
