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.

    It used to be a matter of fact when Peter Pan—a character from James Matthew Barrie's 1911 book—said:“All children,except one,grow up.”{#blank#}1{#/blank#}

    According to the NPD Group,a US market research company,sales of toys to adults in the UK increased by more than 20 percent in 2016,three times the pace of the children's toy market itself.These toys ranged from puzzles and Lego building sets（乐高积木）to vehicle models and action figures.And more than half of the sales came from millennials—people born between the 1980s and 2000s.“Adults of the 21st century are channeling their inner child, one toy at a time,”commented website Koreaboo{#blank#}2{#/blank#}According to Frederique Tutt,all analyst at NPD,the motivation of these grown-ups is to escape the stress of today's fast-paced world.{#blank#}3{#/blank#} “It reminds me of the playful side of life,”Rob Willner,a 25-year-old PhD student in the UK,told The Telegraph when talking about his love for Lego,which he said brings him both comfort and entertainment.

    {#blank#}4{#/blank#}To Frank Furendi,a professor at the University of Kent in The UK,the fact that so many adults are pursuing "the thrills of youth" is the evidence that "adulthood has got nothing attractive about it anymore",he told The New York Times."That's actually quite sad."

    {#blank#}5{#/blank#}According to Canadian comic book artist Todd McFarlane,collecting toys could simply be a way for people to express their individuality."It's just pop culture stuff.It's stuff that says,I like a little of this and I like a little of that,"he told ABC,News."It's no big deal."So now that over 100 years have passed since Peter Pan,perhaps it's time to introduce a new "fact",as stated in the tagline of the UK fashion brand KIDULT:"Growing old is mandatory（强制性的）,but growing up is optional."

A.But scientists are probably just worrying too much.

B.Why do these kidults turn to toys for pleasure and comfort?

C.This is also why these adults are sometimes referred to as "kidults".

D.They are driven toward the more immediate pleasures brought by toys than those brought by,say, getting a promotion,which is far less easy to achieve.

E.The scientists are concerned that those kidults show roo much individuality.

F.But this "fact" doesn't seem to apply to today's world anymore.

G.Despite this,some social scientists see the trend as disturbing.

    Winter is a really fun time of the year—it's great to have snowball fights and build snowmen{#blank#}1{#/blank#} When it's cold outside and you're not prepared, you can feel uncomfortable. Lucky for you, learning how to stay safe is not difficult.

    ●{#blank#}2{#/blank#} Wearing thick clothes is the best way to stay warm in the cold. Depending on where you live and how cold it is, some kids may need more clothes, some less.

    ●Take that hat. You maybe wear a large overcoat and ready to go, but are you forgetting something?{#blank#}3{#/blank#} You'll stay much warmer with a hat than without one—tons of body heat escapes right from your head.

    ●Drink up. Sounds like advice for hot weather, not cold weather, right?{#blank#}4{#/blank#} When you're outside in the cold and breathing hard, your body loses a lot of water through your breath. And the best way to get that water back is to drink up!

    ●Take it easy. Sometimes if you're out having fun, it's easy to forget to pay attention to your body. But if your body temperature drops even 4 or 5 degrees while you're out side, it can make you feel terrible{#blank#}5{#/blank#} And if you ever feel weak, those are signs that you have to take it easy indoors for a while.

A.Love those clothes.

B.Have a snowball fight.

C. Pull a hat onto your head.

D. That's why you need to be careful with your body s signals.

E. Well, the truth is that it's good advice for both kinds of weather.

F. but you have to know how to be safe while you're out having fun.

G. You can stay outside as long as possible to fully enjoy your snow days.

    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 synapses 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.

A. We should also try to sleep well the night before.

B. It's as if the brain is preserving its most important memories.

C. That's why students do better in tests if they get a chance to sleep after learning.

D. Similarly, when people go for a few days without sleeping, they get sick.

E. The processes take place to stop our brains becoming loaded with memories.

F. Tononi's team measured the size of these connections, or synapses, in the brains of 12 mice.

G. “Sleep is the price we pay for learning,” says Giulio Tononi, who developed the idea.

    Screen Time: How Much Is Too Much?

    Many children spend a lot of time watching or playing with electronic media—from televisions to video games, computers and other devices. {#blank#}1{#/blank#} Perhaps parents now should ease up on their concerns about screen time, at least for older boys and girls.

    Until last year, the American Academy of Pediatrics (AAP) suggested that children and teenagers have no more than two hours of screen time a day. It also suggests that parents balance a child's screen time with other activities.

    {#blank#}2{#/blank#} Christopher Ferguson, who teaches psychology at Stetson University in Florida, notes a lack of evidence supporting reports that too many hours spent playing video games or watching TV is truly harmful.

    Ferguson seems interested in one idea: the link between video games and violent or risky behavior. When he saw results from a recent British survey on screen time, he wanted to know more. The British study found a small negative effect—about a one percent increase—in aggression and depression among children who had six or more hours of screen time a day. {#blank#}3{#/blank#} So, Ferguson and his team examined answers from a survey on risky behaviors. The study involved about 6,000 boys and girls in Florida, whose average age was 16.

    Data from this survey found that American children are also fairly resistant to the negative effects of electronic media. Among those who used screens up to six hours a day, the survey found: a 0.5 percent increase in criminal behavior; a 1.7 percent increase in signs of depression; and a 1.2 percent negative effect on school grades. {#blank#}4{#/blank#} To further argue his point that screen time is not harmful, Ferguson adds that children should become familiar with screen technology. Electronic devices, he says, are a part of our everyday lives.

A. Some negative experiences on social media can and do affect some children.

B. However, some experts question claims that too much screen time is harmful.

C. He wanted to see if there was a similar effect among young people in the United States.

D. So, it is natural that parents should wonder about all the time children spend looking at a screen.

E. The researchers found no increase in risky sex or driving behaviors, use of illegal substances or eating disorders.

F. The researchers suggested that for those children, technology use might get in the way of taking part in other important activities.

    Taking good notes is a time-saving skill that will help you to become a better student in several ways. {#blank#}1{#/blank#} Second, your notes are excellent materials to refer to when you are studying for a test. Third, note-taking offers variety to your study time and helps you to hold your interest.

    You will want to take notes during classroom discussions and while reading a textbook or doing research for a report. {#blank#}2{#/blank#} Whenever or however you take notes, keep in mind that note-taking is a selective process. {#blank#}3{#/blank#}

    The following methods may work best for you.

    ●Read the text quickly to find the main facts and ideas in it.

    ●Carefully read the text and watch for words that can show main points and supporting facts.

    ●Write your notes in your own words.

    ●{#blank#}4{#/blank#}

    ●Note any questions or ideas you may have about what was said or written.

    As you take notes, you may want to use your own shorthand (速记). When you do, be sure that you understand your symbols (符号) and that you use them all the time. Otherwise, you may not be able to read your notes later.
