    While Jennifer was at home taking an online exam for her business law class, a monitor(监控器) a few hundred miles away was watching her every move.

    Using a web camera equipped in Jennifer's Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked —remotely—to prevent Internet searches, and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down?

    In the battle against cheating, this is the cutting edge and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid — that students haven't just searched the Internet to get the right answers.

    Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance.

    Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students' identities using personal information, such as the telephone numbers they once used.

    Other programs can produce unique exams by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test questions are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating.

(1)、Why was Jennifer watched in an online exam?
A、To correct her typing mistakes. B、To find her secrets in the room. C、To prevent her from slowing down. D、To keep her from dishonest behaviors.
(2)、The underlined expression cutting edge in Paragraph 3 is closest in meaning to       .
A、advanced techique B、sharpening tool C、effective rule D、dividing line
(3)、For Internet universities, exams and diplomas will be valid if       .
A、they can attract potential students B、they can defeat academic cheating C、they offer students online help D、they offer many online courses
(4)、Some programs can find out possible cheaters by       .
A、checking the question answering speed B、producing a large number of questions C、scanning the Internet test questions D、giving difficult test questions

    Do you still remember your favorite poem from high school or some other important periods in your life?Why is it that decades later it still stands out in your mind?Probably the main reason is that some aspects of that poem resonates(引起共鸣)with you.In the same way,you too as a school leader can touch the hearts of your staff and students.

    Poetry allows us to experience strong spiritual connections to things around us and to the past.Thus,it can inspire whatever and whomever it touches.The power that poetry has displayed over time and across cultures actually satisfies this common need of the human heart and soul.

    As one of the oldest art forms,poetry has successfully connected various strands of humanity(人性)from one generation to another.Referring to poetry,Hillyer makes a simple yet meaningful statement,“With this key mankind unlocked his heart.”

    School leaders can find and make use of the value of poetry for themselves,their students and their staff members.Beyond the simple use of poetry,techniques of poetry such as metaphors,repetitions and imagery can be used to take advantage of the power of language to transform communication,create meaning and a culture of care and attention.

    Since schools are mainly about people and relationship,school leaders,like poets,are required to inspire and encourage the human heart.The use of poetry—or even of some techniques of poetry—in school leadership not only helps to improve communication,but also serves to meet the human need for inspiration.

    Bats are the only mammals(哺乳动物) that can fly a great distance, but they have another ability. Many bats live a very long time for an animal of their size. European researchers are studying bats to understand why they lives0 long. They hope to make discoveries aimed at fighting the aging process in human beings.

    Last week, the group of scientists said they had identified important biological qualities in some bat species. The group studied bat chromosomes(染色体), a line of genes found in the nucleus(细胞核) of cells. The scientists were most interested in structures connected to the ends of the chromosomes. They are called telomeres(端粒), which protect the ends of chromosomes and shorten each time a cell divides. Scientists believe this shortening process causes cells to breakdown. They say this is what causes aging.

    The European researchers studied 493 bats from four bat species. The group used information that had been gathered over more than 60 years. Of these animals ,the greater mouse-eared bat generally lived the longest, an average of 37 years. The scientists said this and a related species, which are grouped together under the name Myotis, had telomeres that did not shorten with age. Another Myotis bat holds the record for oldest age, reaching 41years. The scientists' findings suggest that these bats cells have the ability to maintain and repair their telomeres. This, they said, helps guard against the aging process.

    Based on its body size, a bat like the greater mouse-eared bat would be expected to live four years. But, these mammals have been found to live nearly 10 times longer than that. The scientists found that only 19 species of mammals live longer than humans when their body size is considered. Eighteen of these are bats.

    One of India's top engineering schools has restricted Internet access in its boarding houses, saying addiction to surfing, gaming and blogging was affecting students' performance, making them lonely and even suicidal.

    Authorities at the best Indian Institute of Technology (IIT) in Mumbai said students had stopped socializing and many were late for morning classes or slept through them. "Now, a student doesn't even know who lives two doors away from him because he is so busy on the Internet," said Prakash Gopalan, dean of Student Affairs. "The old dormitory culture of companionship and socializing among students is gone. This is not healthy in our opinion."

    IIT-Mumbai, with about 5,000 students, is one of the seven IITs across India which are considered to be among the finest engineering schools in the world. They are also a talent pool for global technology giants. But their hard courses, tough competition and lonely campus lifestyle have taken an effect on students. Depressive and dysfunctional lifestyles are known to be common among IIT students, and at least nine have committed suicide in the past five years. Students have unlimited free Internet access in their boarding houses to help them in their studies, but many also use it to surf, chat, download movies and music, blog and for gaming.

    "Starting Monday, Internet access will be banned between 11 p.m. and 12:30 p.m. at IIT-Mumbai's 13 boarding buildings to encourage students to sleep early and to try and force them out of their shells." Gopalan said. But the move has not gone down well with students who say they hate their lives being regulated. "Now they will say we need to listen to a lullaby (摇篮曲) to go to sleep." said Rajiv, an electronics student.
