    British scientists have discovered the willow trees planted at an angle could increase sugars for biofuel production.

    Willow is a fast-growing species. It is already used to produce fuels for the renewable heating and power market. In future it could also help to produce biofuel to power vehicles. It has been known that when willows growing in the wild are blown sideways, they tend to produce more sugars. But for a while it has not been known why this happens.

    Researchers at Imperial College London, led by Dr Nicholas Brereton and Dr Michael Ray of the Department of Life Sciences, have now solved the mystery. When the tree is blown sideways, its genes (基因) produce large numbers of sugar molecules (分子) to straighten the tree upwards.

    “This is an important breakthrough. Our study now shows that natural genetic changes are related to these differences. And this could well be the key to unlocking the future for green energy from willow,” said Dr Brereton.

    The research was carried out under lab conditions. The willows were grown at an angle of 45 degrees. They were compared to willows which grow naturally straight upwards. The team then looked for the same effect among the willows growing on the Isle of Orkney where strong winds cause the trees to bend at extreme angles. They discovered that the Orkney trees produce five times the amount of sugars found in willows grown in sheltered conditions.

    Willow is widely planted across the UK. The results show that biofuel crops such as willows could be grown in climatically changeable conditions where chances of growing food crops are limited.

    The study is published in Biotechnology for Biofuels.

(1)、What may happen when willows are planted in strong winds?
A、They stop growing. B、Few sugars are produced. C、They try to grow sideways. D、Changes in genes take place.
(2)、The Orkney willows ________.
A、are unusually rich in sugars B、grow naturally straight upward C、look taller than ordinary willows D、are stronger than those growing in labs
(3)、Farmers living in changeable climate _______.
A、use biofuel for heating and power B、are encouraged to grow biofuel crops C、can plant different kinds of food crops D、should make their willows grow straight
(4)、Where does this passage most probably come from?
A、A personal diary. B、A travel magazine. C、A scientific journal. D、A newspaper advertisement.

    For as long as I can remember, I've always wanted a personal motto. I wanted a saying that I could really try to live my life by. I mean all the humorous book and storybook heroes always have a personal principle they follow. Good manners! Courage! Keenness! But a part of me could never get myself to create my own motto because I never knew where to start and I never thought I could give one.

    “With great power comes great responsibility.” is a quote by the great writer and philosopher, Voltaire. More familiar, it makes an appearance in the modern day movie performance of the superhero Spider-Man. This saying provides a sense of responsibility for those with actually limitless power.

    “Be good to others and others will be good to you.” is another well-known proverb that has roots in almost all of the major religions. Although it is less practiced today than it is lectured, it is a powerful and good motto to live by. Kindness, in this sense, is the final power in judging every action.

    My personal motto today has an idea – being efficient. Through my limited knowledge, I have come to find that this is simply the best way for me to give insight about who I am and what I believe in.

 Efficiency is a quality that everyone desires for, right? Who doesn't want to be able to not only work fast but to achieve great results? To some, it may appear to be a frightening journey. But to me, it means that I have a lifelong journey to improve the methods and ideas with which I come near my tasks.

    Regardless of what motto you want to live by, I believe that everyone should have one, or two or more. These are all symbols of a perfect story of us, in our own view. And it immediately provides insight to the type of person we were, we are and what we strive to be. We are never meant to be perfect, but it is important to try and live by a belief that will help us reach our potential. All you have to do is know what your excitement is and live by it.

    To develop one's taste in English, the most effective way is to read English books extensively. Yet one may be at a loss to choose the appropriate books, especially as a beginner. As a native Spanish, I would like to share some of my experience.

    My first English novel was Jane Austen's Pride and Prejudice, recommended by many English teachers and professors as an ideal book for English learners. But my experience was somewhat disastrous. I had great difficulty in understanding the novel, let alone enjoying it. It's not the vocabulary that troubled me, but rather the way Austen constructs sentences, and her way of thinking, which seemed too remote to me at that time. My fading enthusiasm was much recovered after reading Hemingway's novel A Farewell to Arms. No long and complicated sentences. And I particularly liked his brief and straightforward (简洁的) style. So my first suggestion is, as a beginner, you'd better choose contemporary novels instead of classical ones.

    However, if you restrict yourself to novels you will miss a lot of treasures. English essays can at once inform you, entertain you, and improve your taste in English. The best example is Bertrand Russell's work. Its language is plain, yet you cannot help feeling the elegance and the peculiar sense of humor. His simple language enables his philosophy within the reach of ordinary people. Here comes my second suggestion—essays are indispensable.

    Never follow others' recommendations and opinions blindly, however famous or influential (有很大影响的) the person might be. We should be open to various ideas, but always think and determine for ourselves. As a saying goes, one man's meat is another man's poison. With that in mind, we are bound to find out our favorite writers through reading and develop our fine taste in English.

    A night at the movies is always a good idea. But when you leave the theater and realize you just dropped $45 on a ticket and some snacks, you'll wish you had been patient enough to wait until the movie came out on Netflix. The average movie ticket price in the United States in 2000 was $5.39; now, a ticket is over $9.

    The main reason that movie tickets have gotten so expensive is because of inflation(通货膨胀). It was actually more expensive to go to the movies in the 70s than it is now. A ticket in 1978 cost $2.34. If you plug that into an inflation calculator, the same ticket would cost you $9.46 today. According to the National Association of Theater Owners, the average cost for a ticket today is $9.11.

    Another reason you need to dip into your life savings to see a movie on the big screen is that theaters are competing with streaming services that produce their own films, such as Netflix, Hulu, and Amazon. And let's be honest, sitting at home on your couch or in your bed is more comfortable than sitting in a cold theater.

    Because of streaming technology, movie theaters have to do something to bring in customers. Attractions­including alcohol, reclining seats(躺椅), surround sound, and 3-D movies are all examples of that. And those upgrades come at a price, leading to more expensive tickets.

    "There's all that extra cost, and it's really important for theater owners and companies to make that experience as enjoyable as possible," Patrick Corcoran, vice president of the National Association of Theatre Owners told Marketplace. "Because you're offering a superb experience­audience expectations are for the latest and greatest technology. Audiences are willing to pay more for a particular experience."
