Ali, the boxing legend, died on Friday night at 74，after a Long battle with Parkinson's disease.

    Cassius Clay (Ali) was just 12 years old in 1954 when he got ready to beat the boy who stole his bicycle in his hometown of Louisville, Ky. But a local policeman warned him that he'd need to learn to box first. At just 89 pounds, Clay had his first fight and his first win just weeks later, according to Bleacher Report. By 1964, he was the heavyweight champion of the world, alter upsetting Sonny Liston.

    In 1969, he was forbidden to do boxing over his refusal to join the army and go to Vietnam. Ali was reportedly drowning in debt and still appealing his conviction(上诉).He made pocket change by touring colleges to discuss the war, and, as Playbill points out, he starred in the Broadway musical, Buck White.

Ali sang nearly every song in the musical, playing a black lecturer addressing a meeting organized by a black political group. But he would never return to the stage after his conviction was cancelled.

    In November 1990, Ali met with Iraq president Saddam Hussein in Baghdad on a "good-will tour" in an attempt to negotiate the release of 15 Americans held hostage(人质)in and Kuwait.  Ali was criticized by then-President George H. W, Bush and The New York Times, both of whom expressed concerns that he was fueling propaganda (宣传) machine.

    Despite running out of medicine for his disease and waiting more than a week to talk to Hus-rein, Ali was able to bring all 15 of a group of American war prisoners home.

    We all know the feeling: looking at the computer screen, pretending to be interested in our homework, even though we really feel bored. But such feelings may soon be at an end, says Dr. Harry Witchel, head of the Essex Medical School. He believes that computers of the future will notice when people feel bored and even take action to stopit.

    Before you get concerned, the machine won't be reading your mind. It will be observing the many movements you make while using a computer. It's not interested in the big movements needed to use the machine — like moving a mouse or touching a screen — but small, barely noticeable movements like closing your eyes, moving in your seat or rubbing your face. Witchel calls these “boredom movements" and says they show how interested the person is in what they are reading or watching. The higher the interest level, the less movement!

    To test his theory, Witchel invited 27 people to perform various computer-based tasks. The activities ranged from playing online games (an interesting task) to reading documents like government laws that most people would find boring.

A special video camera followed the participants' movements as they completed each task. Just as the researcher expected, the “boredom movements" greatly decreased, by as much as 42%，when the subjects were very interested in what they were reading or seeing.

    Fortunately, Dr Witchel isn't planning to use his results to create machines that report students who are not paying attention at school. Instead, he wants “movement sensing” technology to be built into future computers in order to improve students' computer-based learning experience.

    The scientist says that by measuring the students' interest level as they work, educators will be able to adjust their materials in real-time to keep students focused. Witchel also believes that the technology can provide filmmakers with honest audience opinions and in the future, help to develop more intelligent robots.

    Guide to Stockholm University Library

    Our library offers different types of studying places and provides a good studying environment.

    Zones

    The library is divided into different zones. The upper floor is a quiet zone with over a thousand places for silent reading, and places where you can sit and work with your own computer. The reading places consist mostly of tables and chairs. The ground floor is the zone where you can talk. Here you can find sofas and armchairs for group work.

    Computers

    You can use your own computer to connect to the wifi specially prepared for notebook computers; you can also use library computers, which contain the most commonly used applications, such as Microsoft Office. They are situated in the area known as the Experimental Field on the ground floor.

    Group-study Places

    If you want to discuss freely without disturbing others, you can book a study room or sit at a table on the ground floor. Some study rooms are for 2-3 people and others can hold up to 6-8 people. All rooms are marked on the library maps.

    There are 40 group-study rooms that must be booked via the website. To book, you need an active University account and a valid University card. You can use a room three hours per day, nine hours at most per week.

    Storage of study material

    The library has lockers for students to store course literature. When you have obtained at least 40 credits(学分), you may rent a locker and pay 400 SEK for a year's rental period.

    Rules to be followed

    Mobile phone conversations are not permitted anywhere in the library. Keep your phone on silent as if you were in a lecture and exit the library if you need to receive calls.

    Please note that food and fruit are forbidden in the library, but you are allowed to have drinks and sweets with you.

    Being physically active three times a week reduces the odds of being depressed by about 16%, according to new UCL research carried out as part of the Public Health Research Centre.

    The study, published in JAMA Psychiatry, found a two-way relationship between depression and physical activity. People who increased their weekly activity were reported to have fewer depressive symptoms but those with more depressive symptoms were less active, particularly at younger ages.

    Researchers followed 11,135 people born in 1958 up until the age of 50, recording depressive symptoms and levels of physical activity at regular intervals in adulthood. They found that each additional activity period per week reduced odds of depression by 6%. In England 19% of men and 26% of women are currently classed as "inactive", and this study suggests that activity could significantly improve their mental as well as physical health.

    "Assuming the association is causal, physical activity has a protective effect against depression. If an adult between his twenties and forties who isn't physically active became active 3 times per week, he would reduce his risks of depression by about 16%," said Dr Snehal of the UCL Institute of Child Health, lead author of the study.

    Professor Mark，Director of the Public Health Research Centre, said: "Many people are already aware of the benefits of physical activity on their general health, but now we are seeing more evidence that suggests it also has a positive effect on a person's mental well-being. The latest research highlights just how important it is to ensure that people are working and living in environments that allow them to be both physically active and mentally healthy."

Lisinopril

    What is lisinopril? Lisinopril is a medicine to treat high blood pressure. This medicine is only available on prescription. It comes as tablets. It also comes as a liquid for people who find it hard to swallow tablets, but this has to be ordered specially by your doctor.

    Important information

    To make sure lisinopril is safe for you, tell your doctor if you have:

    Heart, liver or kidney problems

    Diabetes (糖尿病)

    Higher levels of potassium (钾) in your blood

    Women who are pregnant can't take the medicine. It could harm the unborn baby.

    How should I take lisinopril?

    Take lisinopril exactly as prescribed by your doctor. Follow all directions on your prescription label. Your doctor may sometimes change your dose (剂量) to make sure you get the best results.

    Drink plenty of water each day while you are taking this medicine.

    Lisinopril can be taken with or without food.

    Your blood pressure needs to be checked often, and you may need frequent blood tests.

    What if I forget to take it?

    If you miss a dose of lisinopril, take it as soon as you remember. If you don't remember until the following day, skip the missed dose. Do not take a double dose to make up for a forgotten one. If you forget doses often, it may help to set an alarm to remind you.

    What should I avoid while taking lisinopril?

    Avoid drinking alcohol, because it can further lower your blood pressure and may increase certain side effects of lisinopril.

    Avoid getting up too fast from a sitting or lying position, or you may feel dizzy. Get up slowly and steady yourself to prevent a fall.

    Big Ben is not the name of a man. It is the name of a huge(庞大的)clock in London. London is the capital of England. This clock has four faces. So，no matter where you stand, you can read the time on the face of Big Ben. Each face is the size of a double decker(层)bus. The hands are about four metres long. It is about the size of two people standing on top of each other. If you go to London, you may want to visit the Houses of Parliament(国会大厦). There you will find Big Ben sits at the top of the clock tower(塔)in the Houses of Parliament. Maybe you will hear it as well as see it. The huge clock makes such a loud noise. "Ding dong, ding dong, "it goes every quarter of an hour.

    The clock was named after a big man. He was Sir Benjamin Hall. This man did much building work in London many years ago.
