Building Trust in a Relationship Again

        Trust is a learned behavior that we gain from past experiences, {#blank#}1{#/blank#} .Trust is a risk. But you can't be successful when there's a lack of trust in a relationship that results from an action where the wrongdoer takes no responsibility to fix the mistake.

Unfortunately, we've all been victims of betrayal. Whether we've been stolen from, lied to , misled, or cheated on, there are different levels of losing trust. Sometimes people simply can't trust anymore, {#blank#}2{#/blank#} . It's understandable, but if you're willing to build trust in a relationship again, we have some steps you can take to get you there.

        {#blank#}3{#/blank#} having confidence in yourself will help you make better choices because you can see what the best outcome would be for your well-being.         

• {#blank#}4{#/blank#} If you've been betrayed, you are the victim of your circumstance. But there's a difference between being a victim and living with a “victim mentality”. At some point in all of our lives, we'll have our trust tested or violated.
•             You didn't lose “everything”. Once trust is lost, what is left? Instead of looking at the situation from this hopeless angle, look at everything you still have and be thankful for all of the good in your life. {#blank#}5{#/blank#} instead, it's a healthy way to work through the experience to allow room for positive growth and forgiveness.
•    A, Learn to really trust yourself.
•    B, It is putting confidence in someone.
•    C, Stop regarding yourself as the victim.
•    D, Remember that you can expect the best in return.
•    E, They've been too badly hurt and they can't bear to let it happen again.
•    F, This knowledge carries over in their attitude toward their future relationships.
•    G, Seeing the positive side of things doesn't mean you're ignoring what happened.

    Sleep, as we know, is important to us because it helps restore tired organs and tissues in our body. But how much sleep do we actually need?

{#blank#}2{#/blank#}

    For most of us, eight hours seems to be about the right amount. Yet we know that there are a great many people who get along perfectly with less sleep and some who may even need more. A great deal depends on the way we live. But a good general rule to follow is to sleep as long as we have to in order to feel happy and be able to work at our best when we are awake.

{#blank#}3{#/blank#}

    There are actually different levels of sleep. There is a deep sleep and a shallow sleep. In a shallow sleep our body does not get the same kind of rest as it gets in a deep sleep, so that after eight hours of a shallow sleep we may still feel tired. But a short deep sleep can be very restful.

{#blank#}4{#/blank#}

    Alexander the Great was able to get a deep sleep whenever he needed it. Once, during the night before an important battle, he remained awake longer than anyone else. Then he wrapped himself in a cloak and lay down on the earth. He slept so deeply that his generals had to wake him three times to give command to attack!

    Normally when we go to sleep, our “ sleep center” blocks off nerves so that both our brain and our body go to sleep. One prevents us form wanting to do anything and the other makes our internal organs and limbs go to sleep. But someone will fall asleep (brain sleep) and keep on marching, because his body is not asleep!

    A peer is a person who is about the same age as you. Peers affect your life, whether you know it or not, just by spending time with you.

    {#blank#}1{#/blank#} Maybe another student in your science class taught you an easy way to remember the planets in solar system. Maybe you got others excited about your new favorite book and now everyone's reading it. However, sometimes peers affect one another in another way{#blank#}2{#/blank#} Maybe a kid in the neighborhood wanted you to steal with him.

    Some kids give in to peer pressure because they want to be liked, to fit in, or because they worry that other kids may make fun of them if they don't go along with the group.{#blank#}3{#/blank#} The idea that “everyone's doing it” may influence some kids to leave their better judgments or their common senses behind.

    Peer pressure can be extremely strong and hard to get rid of. Experiments have shown how peer pressure can influence someone to change her/his mind from what she/he knows for sure is a correct answer to the incorrect answer-just because everyone else gives the incorrect answer!{#blank#}4{#/blank#}

    {#blank#}5{#/blank#} Paying attention to your own feelings and beliefs about what is right and wrong can help you know the right thing to do. Inner strength and self-confidence can help you stand firm, walk away and resist doing something when you know better.

A. Peers can have a good effect on one another.

B. Peer pressure is the direct influence on people by peers.

C. Good peers may give you a hand when you are in trouble.

D. That holds true for people of any age in peer pressure situations.

E. Maybe one kid in school tried to get another to cut class with him.

F. It can be hard to walk away from peer pressure, but it can be done.

G. Others may go along because they are curious to try something new that others are doing.

    Music is very powerful. The kind of music you listen to says a lot about who you are. What music you choose to listen to today will help to determine what type of person you are tomorrow. Be careful about what type of music you choose to listen to. Music can either build you up or tear you down.

    Garbage in, garbage out

    In almost all categories of music, there are artists that deliver positive messages through their music and then there are artists that deliver destructive, hateful messages in their music. The kind of music you choose to listen to will help determine the level of success you achieve in life. Think negative thoughts and you will attract negative into your life. Think positive thoughts and you will see the positive in your life. Opportunities come to the optimists in life. When you entertain negativity in your life, opportunities are often lost or ignored.

    Use Positive Music to get what you want out of life

    Actively choose music with a positive message to listen to. Making this conscious choice will lead to positive experiences in your daily life. Music has a powerful effect on our beliefs and our actions. Being active in choosing the music we listen to will lead to a happier and fulfilling life. If you aren't happy with the current state of your life, a great place to start changing it for the better is to choose better music to listen to.

    Not convinced that you should listen to positive music?

    Consider that all action is preceded(先于) by a thought. It's impossible to take an action without having some thought about the action before you do it. Where do your thoughts come from? They come from what you are listening to, what you are seeing and who you are hanging out with. These influences over time, are responsible for our beliefs and ultimately our actions.

    How to make positive changes in your life

    Choosing music with a positive message is a great way to start making positive changes in your life. Don't you like where your life is headed? Changing the music you're listening to is an important first step towards creating a different, more positive life for yourself.

AlphaZero--an Updated Model of AI

    Soon after Garry Kasparov, the former world chess champion, lost his rematch against IBM's Deep Blue in 1997, the short window of human-machine chess competition slammed shut forever. Unlike humans, machines keep getting faster, and today a smartphone chess app can be stronger than Deep Blue. However, as people see with the new AlphaZero system, machine dominance has not ended the historical role of chess as a laboratory of cognition.

    Much as airplanes don't flap their wings like birds, machines don't produce chess moves like humans do. Based on a generic algorithm (算法), AlphaZero incorporates deep learning and other AI techniques like Monte Carlo tree search to play against itself to develop its own chess knowledge. Unlike the traditional program Stockfish, which employs many preset evaluation functions as well as opening and endgame moves, AlphaZero starts out knowing only the rules of chess, with no preset human strategies. In a few hours, it plays more games against itself than have been recorded in human chess history. It teaches itself the best way to play, reevaluating the relative values of the pieces. It quickly becomes strong enough to win 28, draw 72, and lose none in a victory over Stockfish. Since AlphaZero can program itself, this superior understanding allows it to outclass the world's top traditional program despite calculating far fewer positions per second. It's the typical example of the cliché, "work smarter, not harder".

    AlphaZero shows that machines can be the experts, not merely expert tools. Explainability is still an issue—it's not going to put chess coaches out of business just yet. But the knowledge it produces is information humans can learn from. AlphaZero is surpassing humans in a profound and useful way, and researchers are working on transferring the knowledge acquired from AlphaZero to other fields.

    Machine learning systems aren't perfect. Even though great progresses have been achieved, AI algorithms are still struggling on open problems such as computer vision, natural language understanding... There will be cases where an AI will fail to detect exceptions to its rules. Therefore, as Kasparov writes, "We must work together to combine our strengths. I know better than most people what it's like to compete against a machine. Instead of raging against them, it's better if we're all on the same side."

    A fresh-faced batch of teenagers just began a new school year, but will they get the most out of it? In the mornings, many are forced to get to school much too early. And at night, screens are a temptation that's hard to resist. This double whammy (双重灾难) is a perfect lesson in sleep deprivation (剥夺).

    Three out of every four students in grades 9 to 12 fail to sleep the minimum of eight hours that the American Academy of Medicine recommends for their age group. In most cases, insufficient sleep results in reduced attention, preventing students' progress and lowering grades. More alarmingly, sleep deprivation may lead to physical and emotional problems.

    It is important to understand why teenagers have a particularly hard time getting enough sleep, and what adults need to do to help. First, a reminder of the basic biology: Adolescents are no longer the morning larks of their younger years. They become rewired as night owls, staying awake later and then sleeping in. This is mostly driven by changes in the way the brain responds to light.

    New technology habits aren't helping. More teenagers now turn to activities involving screens at night. The growth in screen time is particularly problematic for sleep. The blue light emitted by LEDs, TVs, tablets and smartphones suppresses the body's secretion (分泌) of melatonin, the hormone that signals it's time to sleep. Overdosing on screens at night effectively tells the brain it's still daytime, delaying the body's cues to sleep even further.

    Parents should inform their kids of the time that can be spent on screens, and praise children who show signs of regulating their own media consumption. In the hour before bedtime, there should be a suspension on bright lights in the home, avoiding devices and harsh LED bulbs in kitchens and bathrooms.

    In 2016, the American Academy of Pediatrics recommended that middle and high schools start no earlier than 8: 30 a. m., a policy now backed by the American Medical Association and many other health organizations.

    Parents also need to join forces with community leaders, sleep scientists, health professionals and educators to put school start times on the local, then state agendas.

    Whenever schools have managed the transition to a later start time, students get more sleep, attendance goes up, grades improve and there is a significant reduction in car accidents.
