Life is just like a box. Inside it are happiness and sorrow, failure and success, hope and despair. Life is a learning process. Experiences in it teach us new lessons and make us a better person.

    Love

    Love plays a key role in our life. Love makes you feel wanted. Without love a person could become cruel and violent. In the early stage of our life, our parents are the ones who show us with unconditional love and care. They tell us what is right or wrong, good or bad. {#blank#}1{#/blank#}.It is only after marriage and having kids that a person understands and becomes sensitive to the feelings of others. Kids make a person responsible and mature and help us to understand life better.

    Happiness and Sorrow

    Materialistic happiness is short­lived, but happiness achieved by bringing a smile on others gives a certain level of fulfillment.  {#blank#}2{#/blank#}.No mind is happy without peace. We realize the true worth of happiness when we are in sorrow. Sorrow is basically due to death of a loved one, failure and despair. But these things are temporary and pass away.

    Failure and Success

    {#blank#}3{#/blank#}.It helps us to touch the sky, teaches us to survive and shows us a specific way.

    Hope and Despair

    Hope is what keeps life going. Parents always hope their children will do well. Hope makes us dream. Hope builds in patience. {#blank#}4{#/blank#}, because after every night there is a day. Nothing remains the same. We have only one choice—keep moving on in life and be hopeful.

Life teaches us not to regret over yesterday, for it has passed and is beyond our control. Tomorrow is unknown, for it could either be right or dull. {#blank#}5{#/blank#}, so that we will enjoy a better tomorrow.

    Every animal sleeps,but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month.{#blank#}1{#/blank#} 

    One idea is that sleep helps us strengthen new memories. {#blank#}2{#/blank#} We  know that, while awake,fresh memories are recorded by reinforcing (加强)connections between brain cells, but the  memory processes that take place while we sleep  have been unclear.

    Support is growing for a theory that sleep evolved so that connections between neurons(神经元)in the brain can be weakened overnight, making room for fresh memories to form the next day.  {#blank#}3{#/blank#}

    Now we have the most direct evidence yet that he is right. {#blank#}4{#/blank#} The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep,showing that the connections between neurons weaken while sleeping.

If Tononi's theory is right, it would explain why, when we miss a night's, we find it harder the next day to concentrate and learn new information —our brains may have smaller room for new experiences.

    Their research also suggests how we may build lasting memories over time even though the synapscs become thinner. The team discovered that some synapses seem to be protected and stayed the same size. {#blank#}5{#/blank#}  “You keep what matters,” Tononi says.

    Everything you do to protect the planet helps all living things, including humpbacks（座头鲸）and other species of whales that live in oceans worldwide. And yes－just one kid, like you, can make a difference.{#blank#}1{#/blank#}

    Don't litter. Rubbish thrown away carelessly outside often washes into storm drains（排水沟）, which empty into rivers and eventually flow to the oceans.{#blank#}2{#/blank#}including whales.

    Say, “No bag, thank you.” Whether you're buying toys, snacks, or clothes, tell the checkout person you don't need a bag.{#blank#}3{#/blank#}you'll help reduce the 100 million plastic bags that each year block sewers（下水道）, and get swallowed by whales, sea turtles, and other wild life.

    Plant a tree.{#blank#}4{#/blank#}They produce oxygen and absorb carbon dioxide（二氧化碳）, a gas that animals, including humans, produce naturally as they breathe. But because carbon dioxide also comes from cars and factories, there is too much of it in the atmosphere, which is contributing to global warming. If everyone planted one tree, those trees would remove a large amount of carbon dioxide from the atmosphere.

    {#blank#}5{#/blank#}Every time you leave a room for more than a minute, turn off the light you're using. In this way, you save energy and keep greenhouse gases out of the atmosphere.

    Try the family challenge! Many streams and rivers are polluted and littered with rubbish. You and your family can help preserve the waterways by joining others in your community to pick up rubbish.

A．Trees help clean the air we breathe

B．Turn off the light

C．Avoid driving cars

D．By carrying your own reusable bag

E．Treat them like friends

F．Here are ideas for easy small things you can do

G．Pollution is a growing problem for all the Earth's oceans and its wildlife

    The new school year is right around the corner, and the adjustment to returning to school may take a few weeks.{#blank#}1{#/blank#} Kids today are faced with far more than learning new material. Interacting with teachers and other students, bullying (欺凌), peer pressure and school violence are just a few of the challenges children face. The Kern County Sheriff s Office would like to provide the following tips for parents on how to protect your children, and how to teach them to protect themselves.

    {#blank#}2{#/blank#}

    Map out a safe way for your children to walk to school or to the bus stop. Teach your children to always be aware of their surroundings. {#blank#}3{#/blank#} Choose a different route or walk on the opposite side of the street.

    Bus Safety

    Make sure your children arrive at least five minutes early for the bus. Be aware that bullying often happens on the bus. Ask your children about their bus rides, who they sit with, and what goes on in the bus.{#blank#}4{#/blank#}

    After School

    {#blank#}5{#/blank#} It could be your parents or any of your neighbors who can take care of your children for you. Make sure they inform you of it the moment your children arrive home.

    At School

    Teach your children to resolve problems without fighting. Many parents mislead their children to solve problems by force in fear that their children may be bullied at school, which will only lead to more trouble. Anyway, encourage your children to report bullying behavior, either as a victim or a witness.

A. Getting to School

B. Preparing for School

C. Encourage them to report any bullying behavior on the bus.

D. Some kids just can't wait to return to school after a long holiday.

E. Have your children check in with an adult as soon as they get home.

F. Be aware of slow moving vehicles or parked vehicles that appear to be occupied.

G. Returning to school can be fun and exciting, but it can also be difficult for some children.

    Violent Games: Fun or Harmful?

    If you play lots of video games, you've probably blown a zombie(僵尸) into tiny bits. {#blank#}1{#/blank#} Many adults worry that playing such games could make children act violently in real life. Is that true?

The American Academy of Pediatrics(儿科) says that violence in any kind of media — from TV to music to video games — presents a risk to kids' health. A number of studies have shown a link between video games and aggression, including one published in JAMA Pediatrics in 2014, which found that kids who played violent video games showed an increase in aggressive thoughts and behaviors. {#blank#}2{#/blank#}

    But not all studies agree that violent games cause kids to act out. Another study replaced violent deaths with evaporation(蒸发) in a game. {#blank#}3{#/blank#} People who played the non-violent game without any training were more aggressive afterward than people who played the violent version but learned to control themselves first.

    And here's an even stranger fact: When violent video games are released, people carry out fewer violent crimes! Why? {#blank#}4{#/blank#} Steve Levitt, coauthor of the book Freakonomics, said, “If you can make video games fun enough, then kids will stop watching TV, and they'll stop going out and creating violent disorder on the street.”

What do you think? {#blank#}5{#/blank#}

A. One possible explanation: potential criminals are at home playing the new game.

B. Then, before playing the game, some people received training and others didn't.

C. More than 3,000 kids answered survey questions during a two-year period.

D. For example, thinking it's OK to hit someone you don't like.

E. Have you ever played any violent video games?

F. Do violent video games cause bad behavior?

G. Some games even pile up dead bodies.

    It's very common these days for people to take some sort of regular exercise each week. But if you've never done it before, what's the best way to go about it? {#blank#}1{#/blank#} He or she will create a personalized plan for you based on your aims.

    However, each hourly session can be steep considering you have to pay both the personal trainer and membership of the gym, too. So what's left? Well, if you have the courage to do it, you can make your own plan. It's relatively easy to do if you have the know-how. {#blank#}2{#/blank#}

    First, keep your fitness goal in mind. Are you looking to slim down or increase your abilities? Whatever it is, make sure the things you choose to do are achieving that goal. Next, do your research. {#blank#}3{#/blank#} Watch as many of these as possible, but make sure to be a little critical of them — everyone has a different physique and what works for one may not work for another. Finally, keep your feet on the ground. {#blank#}4{#/blank#} It takes at least three months to see any realistic body changes. And don't be overzealous(过度热衷的) — never work in pain — a good workout is difficult and challenging, but never painful. Pain means you are damaging yourself.

    If nothing else, focus on calisthenics (健身操). {#blank#}5{#/blank#} Do as many of one exercise as you can without stopping, and then try and repeat that number twice more — make sure you sweat, and don't forget to rest for a minute in between each activity!

A. Be patient with yourself and set realistic goals.

B. But before you do, here are some basic pointers.

C. Well, many people make use of a personal trainer.

D. They just don't want to design their own workout plan.

E. These days, social media is full of fitness videos and advice.

F. Find a way to make each exercise more difficult as you get in shape.

G. These are the basic body movements which everyone can do anywhere.
