    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.

    It is widely acknowledged that it is by no means an easy task to bring up a child well. And our ancestors already understood it well. As an old proverb says, “It takes an entire village to raise a child.” That is being quoted more and more often these days. And I'm pleased about that.

    Parents need to be involved in their children's education in many ways. Helping children with homework and studying, going on a field trip, teaching a craft or coaching a child's sports team are all great ways to be involved with your child's education. And don't forget to communicate with teachers—they need and respect your input. Studies show that children learn more and schools function better when parents and schools work together.

    Communities can help children create and achieve new goals. There are other ways such as helping with homework. reading to a child, coaching a children's team, providing emotional support, helping solve problems and building self-esteem(自尊). Kids need role models and advisers can be role models by sharing their experiences and wisdom.

    Businesses can also help shape our children's future—invite a class from your local school to visit your workplace. You may be providing a glimpse that opens a new world of possibilities. Show students what goes on during a typical day. Give a mini course for students: how products are made; how machinery works. You may have a developing electrician, a teacher, a nurse, or even a newspaper reporter on your hands.

    It really does lake an entire village to raise a child. So share the responsibility-and the joy—of bringing a child to his or her full potential.

    Education is not a bystanders sport. Numerous researchers have shown that when students participate in classroom discussion they hold more positive attitudes toward school, and that positive attitudes promote learning. It is no coincidence that girls are more passive in the classroom discussion and score lower than boys on SATs.

    We found that at all grade levels in all communities and in all subject areas boys controlled classroom communication. They participated in more interactions than girls did, and their participation became greater as the year went on.

    Our research contradicted the traditional assumption that girls control classroom communication in reading while boys in math. We found that whether the subject was language arts and English or math and science, boys got more than their fair share of teacher attention. That teachers talk more to male students is simply because boys are more aggressive in grabbing their attention by calling out answers to the teachers' questions first. While girls sit patiently with their hands raised or keep silent. Psychologist Lisa Serbin and K.Daniel O'Leary, then at the state university of New York at stony brook studied classroom interaction at preschool level and found that teachers gave boys more attention, praised them more often and were at least twice as likely to have extended conversations with them.

    Years of experience have shown that the best way to learn something is to do it yourself. It is also important to give students specific and direct feedback about the quality of their work and answers. Teachers behave differently depending on whether boys or girls are active to provide answers during discussions. During classroom discussion, teachers in our study reacted to boys answers with powerful, precise and effective responses, while they often gave girls mild and unclear reactions because of their silence. Too often, girls remain in the dark about the quality of their answers. Active students receiving precise feedback are more likely to achieve academically. And they are more likely to be boys.

    This kind of communication game is played at work, as well as at school. As reported in numerous studies, it goes like this.

    Men speak more often and frequently interrupt women.

    Listeners recall more from male speakers than from female speakers, even when both use a similar speaking style and cover the same content.

    Women participate less actively in conversation. They do more smiling and gazing, and they are more often the passive by standers in professional and social conversations among peers.

    Women often their own statements into unsure comments. This is accomplished by using qualifiers and by adding tag question. These uncertain patterns weaken impact and signal a lack of power and influence.

    Only when girls are active and treated equally in the classroom will they be more likely to achieve equality in the workplace.

    J.K. Rowling is the writer of Harry Potter, which is now one of the bestsellers in the world.

    J.K. Rowling was born in Bristol on July 31st, 1965. She has one sister who is two years younger than her. Both girls loved listening to their father reading bedtime stories to them. They especially loved stories about magical worlds. Rowling wrote her first story, called Rabbit, at the age of six.

    After she graduated from the university, Rowling worked as a translator in London. During this time, on a long train trip in the summer of 1990, the idea came to her of a boy who has magic but doesn't know it. In 1992 Rowling began to teach English. She lived with her baby daughter, Jessica, and spent much time finishing the first Harry Potter book for young readers. It appeared in June 1997. To her surprise, the book was greatly successful. The film came out in November 2001. Now Harry Potter series(系列) is popular with people of all ages and about 60 million books were sold in 200 countries.

    Why has the series been so successful? There are a few things. Many other magical stories take place in faraway lands or in past or future times. But Harry lives in modern England. He's also a very normal boy: polite, friendly, brave and clever. So when other children read about Harry, they can imagine being like him.

    J.K. Rowling is very happy with the success, and she is now busy finishing the whole series of seven books. She's writing full time and she's really enjoying life. She says she will go on living a normal life with her daughter and writing children's books.
