If you need to spend time on the road，it's important to find ways to keep safe on your feet．Don't suppose it's your right of way. Yes，you might be crossing at the right place，at the right time，within the crosswalk area，but you are still exposed to danger. It could be a distracted driver，or a cyclist with a loose sense of traffic rules，so you could still get hurt．You can be in the right legally，but that won't be much help when you're in the hospital.

    Follow pedestrian(行人) signals. Just as drivers aren't supposed to speed up to beat a light when crossing through an intersection，pedestrians need to take the same care when obeying their own signals．If the hand is flashing and the countdown is into single digits (数字), stay where you are．Trying to outrun the flashing hand is unsafe，especially as cars try to clear the intersection before the light turns red．

    Give drivers enough time to stop when crossing. Don't suppose that drivers will jam on their brakes when you hit the crosswalk signals. Some provinces，such as Alberta, issue （发出）a ticket if you don't give drivers enough time to brake.

    Cross quickly. Once you've followed all of the other rules，and it is safe to cross the street，don't then just wander along in front of six lanes (车道) of traffic. There's no need to run or jog，but respect the drivers who respected you enough to stop for you.

    Just as John Lubbock said, we may sit in a library and yet be in all quarters of the earth. Here are some of the coolest libraries of the world.

    Stuttgart City Library

    Despite a classic white-on-white color, Stuttgart City Library is one of the most visually appealing modern libraries. The amazing modern and simple look is the product of the Korean architect Yi Eun-young. The German library opened in 2011, and cost nearly 80 million euros to construct.

    Kanazawa Umimirai Library

    Architects from the Coelacanth K&H Architects studio designed the Kanazawa Umimirai Library lo create the best reading environment. Healed floors, an outpouring of natural light, and other features were specifically included lo achieve this goal. The wall, which consists of thousands of tiny openings, allows natural lighting into the building, improving the overall feel of the space. This Japanese library was opened in 2011, and reflects the appearance of many modern and simple spaces.

    Library of Congress

    In 1800, Congress set up the Library of Congress in Washington D.C. Fifteen years later, Thomas Jefferson offered his personal library to replace books that were lost when the British set the building on fire in 1814. His books, which took nearly 50 years to collect, varied from texts on science, literature and philosophy, to books in a variety of foreign languages. These days, the Library of Congress offers more than 155 million items and the largest rare book collection in North America.

    State Library of Victoria

    The Slate Library of Victoria, located in Melbourne, Australia, is one of the largest exhibiting libraries in the world. Though it opened in 1856, major repairs took place between 1990 and 2004. The La Trobe Reading Room is one of the library's main attractions due to its visually amazing architecture. The lawn at the library's front attracts hundreds of city folk each day, who gather for lunch or to enjoy the statues there. The library currently contains over two million books, as well as armor (盔甲) of Ned Kelly, a folk hero against the ruling class.

What is a boy?

    Between the innocence of babyhood and the seriousness of manhood we find a delightful creature called a "boy". Boys come in different sizes, weights, and colors, but all boys have the belief: to enjoy every second of every minute every hour of every day and to fill the air with noise until the adult males pack them off to bed at night.

    Boys are found everywhere—on top of, under, inside of, climbing on, swinging from, running around, or jumping to this and that! Mothers spoil them, little girls hate them, older sisters and brothers love them, and God protects them. A boy is TRUTH with dirt on its face. BEAUTY with a cut on its finger, WISDOM with chocolate in its hair, and HOPE of the future with a snake in its pocket.

    When you are busy, a boy is a trouble­maker and a noise. When you want him to make a good impression, his brain turns to jelly, or else he becomes a wild creature bent on destroying the world and himself with it.

    A boy is a mixture—he has the stomach of a horse, the digestion of stones and sand, the energy of an atomic bomb, the curiosity of a cat, the imagination of a superman, the shyness of a sweet girl, the brave nature of a bull, the violence of a firecracker, but when you ask him to make something, he has five thumbs (拇指) on each hand.

    He likes ice cream, knives, saws, Christmas, comic books, woods, water (in its natural habitat), large animals, Dad, trains, Saturday mornings, and fire engines. He is not much for Sunday schools, companies, schools, books without pictures, music lessons, neckties, barbers, girls, overcoats, adults, or bedtime.

    Nobody else is so early to rise, or so late to supper. Nobody else gets so much fun out of trees, dogs, and breezes. Nobody else can put into one pocket a rusty knife, a half eaten apple, a three­foot rope, six cents and some unknown things.

    A boy is a magical creature—he is your headache but when you come home at night with only shattered pieces of your hopes and dreams, he can mend them like new with two magic words, "Hi, Dad!"

    In many developed countries, people who have high degrees begin to work longer than those who don't. About 65% of American men aged 62－74 with a professional degree are in the workforce (劳动人口), compared with 32% of men who only finish high school. This gap is part of a deepening divide between the well-educated wealthy and the unskilled poor. Rapid technological advance has raised the incomes of the highly skilled while squeezing those of the unskilled. The consequences, for individuals and society, are profound (意义深远的).

    The world is facing an astonishing rise in the number of old people, and they will live longer than ever before. Over the next 20 years the global population of those aged 65 or more will almost double, from 600 million to 1.1 billion. The experience of the 20th century, when greater longevity (长寿) translated into more years in retirement rather than more years at work, has persuaded many observers that this shift (变化) will lead to slower economic growth, while the swelling (渐增的) ranks of pensioners will create government budget problems.

    Policies are partly responsible. Many European governments have abandoned policies that used to encourage people to retire early. Even the better-off must work longer to have a comfortable retirement. But the changing nature of work also plays a big role. Pay has risen sharply for the highly educated, and those people continue to reap (获得) rich rewards into old age because these days the educated elderly are more productive than the preceding (先前的) generation. Technological change may well reinforce (强化) that shift: the skills that complement (补充) computers, from management know-how to creativity, do not necessarily decline with age.

    A science teacher from rural Kenya who gives away most of his salary to help poorer students has been awarded the world's best teacher and $ 1 million, beating 10,000 nominations from 179 countries. Peter Tabichi, 36, a maths and physics teacher at Keriko secondary school in Pwani Village, has won the Varkey Foundation Global Teacher Prize 2019.

    Tabichi gives away 80% of his income to help the poorest students at the poorly-equipped and overcrowded school who could not otherwise afford uniforms and books. More than 90% of his students are from poor families and almost a third are orphans or have only one parent. Drug abuse, teenage pregnancies, leaving off their studies, young marriages and suicide are common. Students have to walk 7 km along roads that can become impassable in the rainy season to reach the school and the area can be affected by drought and starvation.

    Despite only having one computer, a poor Internet connection and a student-teacher ratio of 58:1, Tabichi started a "talent nurturing club" and expanded the school's science club, helping students design research projects of such quality that many now qualify for national competitions.

    His students have taken part in international science competitions and won an award from the Royal Society of Chemistry after using local plant life to generate electricity. Tabichi and four colleagues also give struggling students one-to-one tuition in maths and science, visiting students' homes and meeting their families to identify the challenges they face.

    Accepting the prize, Tabichi said Africa's young people would no longer be held back by low expectations." Africa will produce scientists, engineers and entrepreneurs whose names will be one day famous in every corner of the world." he said.

More than 400 athletes across a variety of sports, ages and levels of experience were questioned for the study by sports psychology experts from Staffordshire University and Manchester Metropolitan University. The findings reveal that athletes' belief systems—specifically irrational（非理性） beliefs—are related to poorer self-confidence, and in turn, greater competitive anxiety and depressive symptoms.

"Phrases that reflect self-depreciating（贬低） beliefs such as 'If I lose, I'm a failure' or 'If I face setbacks, it shows how stupid I am' are warning signs," said the authors. Paul Mansell, Lecturer in Sport and Exercise Psychology at Staffordshire University, said, "Despite the psychological benefits of physical activity, studies frequently report poor mental health in athletes, which may be exacerbated by adversities, such as injury, de-selection, and performance pressure. We investigated athletes' beliefs, how they view stress, their levels of self-confidence and put all this data together to work out what might predict psychological well-being. We found irrational beliefs to be a core reason for symptoms of poor mental health in athletes."

This is the first known study that has examined irrational beliefs, self-confidence, and the psychological well-being of athletes all together. Irrational beliefs are extreme, rigid, and illogical ideas that people hold. For example, a person might believe that they "must" get what they want, or that just because they have failed, they are a "complete failure".

"We can all work to help athletes develop mindsets that help them deal with the challenges of sport and life. By encouraging rational and logical beliefs about performance, we can help athletes to stay healthy amidst the high demands of competitive sport," said Paul Mansell.

The author s propose Rational Emotive Behavior Therapy(REBT) as an effective tool for protecting self-confidence. REBT helps athletes to challenge these self-depreciating beliefs and develop beliefs that are more helpful and healthy. For example, rather than believe "I am a failure if I fail", this might be countered with "Failing is not ideal, but it does not mean that I am a failure".
