Visitors to Britain are sometimes surprised to learn that newspapers there have such a large circulation (发行 ). The “Daily Mirror “ and the “Daily express” both sell about four million copies everyday. British families generally buy a newspaper every morning and two or three on Sundays.

    Besides the national papers, there is, however, another branch of the British press which sells almost as many copies. Local newspapers have a weekly circulation of 13 million. Almost every town and county area has one. Nearly all of them hold their own financially (财政 ) and many of them are very profitable (赚钱的 ) .

    These papers are written almost entirely for readers interested in local events-births, weddings, deaths, council (地方会议 ) meetings and sports. Editors prefer to rely on people who know the district well. A great deal of local news is regularly supplied by clubs and churches in the neighborhood and it does not get out to date as quickly as national news.

    The editors must never forget that the success of any newspaper depends on advertising ( 广告) . He is usually anxious to keep the good will of local businessmen for this reason. But if the newspaper is well written and the news items have been carefully chosen to draw local readers, the business men are grateful for the opportunity (机会 ) to keep their products in the public eyes.

    Writer Liu fang's first novel, about the life of a teacher at a rural school in the mountainous province of Guizhou in the 1990s , is greatly similar to her own early years-before she lost her sight and struggled to find a full life in the darkness.

    Liu, 44 , was a Chinese language teacher at No 3 Middle School in the Baiyun district of Guiyang until 2006 , when she could no longer see the characters printed in the textbooks .

    Diagnosed with incurable eye disease , in 1996 , Liu was told she would gradually lose her eyesight over 10 years.That it took her 20 years to walk into darkness makes her have the ability to tell you the difference between the two worlds .She spent the first 10 years gradually accepting the reality , and the second facing it with smiles.

    Fortunately , Liu had many people on her side.Her family and friends helped her overcome the most difficult period of her life. And her own kindness served her well . Liu praised the school's headmaster , who gave her a new post as a psychological consultant(心理咨询师) for students, and planned for professional training for her new role.

    Liu's office is a comfortable place decorated with hand-drawn student pictures , one where children can thoughtfully talk about their problems . Liu takes her job seriously.She donated 5,000 yuan (＄760) from her income to five poor students.After she became famous, all she wanted to do was help for the “left-behind”children.

    Yang Hui , a student who often quarrelled with her parents , said Liu feels like a mother to the student. Yang said She would listen to me patiently , and Liu helped her find the reason she couldn't get along well with her parents .

Liu said , her blindness is an asset . “I guess they trust me because I cannot see them , and they feel I am more concentrated and careful than others while listening to them.”

    How do the world's only flying mammals communicate? Researchers have observed young bats adopting new “dialects” simply by hearing them repeatedly, making them one of the few animals known to have a capacity for vocal (声音的) learning. “These bats may help us clarify the evolution of speech acquisition (习得) skills,” says Yosef Prat, a PhD at Tel Aviv University (TAU).

    For one year, researchers raised 14 Egyptian fruit bat pups with their mothers in controlled area, exposing each young bat to two different vocalizations: the natural call of its mother and a separate recording that varied in pitch (音高) or frequency. They found that the pups in each group developed a dialect like the recording. “The general assumption in this field is that most animals develop their born vocalizations regardless of what they hear, and that human vocal learning abilities have developed during evolution,” says Mr Prat. “The finding that bats learn the common dialect in their rest place was unusual.”

    Scientists know little about the origin of spoken language, which is believed to have appeared in humans within the past 500,000 years. Dozens of theories attempt to explain the complexity of this skill, but none have done so conclusively.

    “Studying vocal communication and vocal learning in animal models is a very useful way to approach the problem,” says Olga Feher, an assistant professor at the University of Warwick in England.

    But animal vocalizations and human speech are very different things, says Jamin Pelkey, a professor at Ryerson University. “All species communicate. Unlike other animals, though, human beings are able to use sound patterns for functions that are far stranger—functions that are imaginative, theoretical, and critical. When speech is involved in these stranger functions, that is what we mean by spoken ‘language'.”

    Many people believe that you lose the ability to learn new languages as you get older. Language experts, however, will tell you that you're never too old to learn a new language. As you get older, it can be more difficult to learn a new language, though.

    Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year, because they need to learn languages to become part of their communities. Adults, on the other hand, are already part of a language community. Learning a new language means becoming part of another language community, and adults rarely get the chance to practice as much as young children do.

    Moreover, children learning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident. Adults, however, often feel stressed to be perfect when learning a new language. This can discourage many people and make it even harder to learn a new language.

    When young children learn a new language, they come to see various languages as a “normal” part of society. This mindset helps them to learn a new language without feeling like they're doing something unusual or “too hard”.

    So if you want to learn a new language, go for it! It's never too late to learn a new language. If you're older, it may take more work, but it can be done. If you're a young child, though, now is the time to step out and learn a new language!

    Studying the DNA of 300 mice has flagged up genes which have been linked to hereditary (遗传的) sight loss for the first time. Researchers say because mice's genes are so similar to humans', their findings could lead to the treatment of more genetic diseases.

    Scientists at the University of California, Davis studied information from a data bank of mice's genetic material. They found 347 genes linked to eye problems, with just 86 of them having been studied in the past.

    Only around 50 to 75 percent of hereditary eye diseases in human can be explained with present science. The researchers believe these hundreds of new genes found in mice could be a key to explaining-and therefore being able to treat the other 25-50 percent.

    "This is extremely valuable for people with hereditary eye disease," said researcher Professor Ala Moshiri. "All researchers are going to start using these data. In the past, we knew the problem was there but we didn't know where to look. Now eye centers can call back patients and screen them for these new genes. We expected that more and more of these genetic diseases will be treatable." Also, the fact is that more than 60 percent of eye problems at birth are ones resulting from the baby's parents!

    Thanks to data from the International Mouse Phenotyping Consortium (IMPC), which is trying to work out what every single gene in a mouse is responsible for, with the aim of translating it to humans, scientists are moving closer to figuring out all genetic causes of blindness. To do this, scientists separate a single gene from other ones at a time and then observe what effect it has on the mouse for a long time. This has so far been done more than 7,000 times and has achieved great success. Researchers are now working alongside eye care centers in Texas and Iowa in order to compare the mice's genes to those of patients.

    Mother Teresa (August 26, 1910-September 5, 1997) was a great woman, who did a lot to improve the social condition of mankind. Due to her contribution in serving the society, she was awarded the Nobel Peace Prize aged 69.

    She was brought up in a Catholic family. When she was only seven, she lost her father. Even as a young child, she was interested in the life of missionaries (传教士). At the age of 18, she decided that she would become a nun. She left her home and went to join the Sisters of Loreto. It was the first step that she made towards providing services for mankind.

    On the 7th of October in the year 1950, Mother Teresa received Vatican permission to start the Missionaries of Charity in Calcutta, the mission of which would be to take care of the needy, the homeless, and people who were shunned by the society. Then it had a number of branches all over the country. The journey of Mother Teresa's Missionaries of Charity started with the setting up of homes for "the Dying".

    In the year 1983, Mother Teresa suffered from a serious heart attack, while she was in Rome. However, she recovered. But, later in 1989, she again got an attack. Her health went worse and in the year 1991, she suffered from pneumonia. Taking her health problems into consideration, Mother Teresa decided to resign (辞职) from the post of head of the order.

    A secret vote was conducted in which all the nuns voted for the stay of Mother Teresa except herself. So, she agreed to continue serving as head of the Missionaries of Charity. Day by day her health was getting worse. On September 5, 1997, exactly nine days after her 87th birthday, this great soul departed for heaven.
