A dog's mind is only equal to that of a two-year-old baby. {#blank#}1{#/blank#} So, they are probably the first to notice any change in the behavior of their masters. Let's do some deep-digging to understand the amazing ability of a dog.

    They sense your feelings. Isn't it strange? {#blank#}2{#/blank#} This is true. A study published in the Animal Cognition（认知）journal says that dogs are known to come to people who appear sad or depressed. It doesn't matter if the person is their owner or a stranger. They have an ability to sense sadness and are attracted to troubled souls.

    {#blank#}3{#/blank#} Dogs can easily tell when you're playing with favorites, and if you reward or play more with other pets, your dog might notice it and feel uncomfortable. As they can't say how they feel, they will scratch, yawn or lick their mouths.

    They smell fear. Let's say you are faced with your worst fear. Would you get scared and run away or just face it? Before choosing how to deal with it, you should remember one thing. {#blank#}4{#/blank#} Research shows that dogs often sense their master's response in dangerous situations. If you fear something and choose to back away, chances are that your pet is going to do the same thing.

    They're watching you. We are all raised as responsible individuals who are taught to respect elders, obey the law and help out people in need from time to time. {#blank#}5{#/blank#} But if you have a dog at home, it is time to be serious about them. Dogs like generous people. So just be careful around your pet; it may judge you on how you behave with others.

A. They sense health problems.

B. They understand when ignored.

C. They know when no one's looking at them.

D. You would be setting an example to your pet.

E. Every time you feel sad, your dog just knows it.

F. But dogs are able to sense everything around them.

G. However, not all of us take these three things seriously.

    I just counted how many foreign languages I've studied so far in my life and it's been twelve!

    I always follow my interests and find ways to put my language learning into things I'm already interested in. I like to read blogs(博客)in other languages.{#blank#}1{#/blank#}. For the most part, bloggers tend to write the same way they speak, so I don't have to worry much about adopting strange terms that are only used in writing.

    Movies are also a really good tool, especially if you can find subtitles in the language you're learning.{#blank#}2{#/blank#}, they will still keep your brain listening and reading in the same language. Music is another way to start listening to things in your new language. Personally, I'm so bad at understanding lyrics(歌词)even in English, so this one doesn't really work for me, but I have friends who learn a language through lyrics. Games are of course also an excellent way of studying a new language. A lot of language learning computer programs include games. I'm super competitive and if I play any of them, I can be hooked for hours.{#blank#}3{#/blank#}.

    When the initial excitement of learning a new language begins to fade, it can be hard to stick with it. The hardest bit for me is when I'm comfortable enough with a language to understand most things and make myself understood. I'm actually stuck at this stage in Norwegian.{#blank#}4{#/blank#}. Ideally I should sign up to take a big language exam. Each time I start getting self-satisfied, it's time to take a new course or sign up for online lessons, or take up some sort of challenge that will require me to level up my skills.

    {#blank#}5{#/blank#}. The best language class I've ever taken was my beginner's Russian course at university where my professor never used any English. It got to the point where I would kind of just forget about English while in Russian class, which helped me to really immerse myself in the Russian language and do a whole lot with the limited Russian I had.

A. That's really uncomfortable

B. Whatever languages they're translated into

C.I also try to think in the language I'm learning

D. It's time well spent if I'm learning the language

E. Computer games always make me feel worn out

F. Though they don't always exactly match what's being said

G.I found them the perfect learning tool because they're usually written in oral language

    Studying longer does not necessarily mean studying better. {#blank#}1{#/blank#} Below are some great ways of learning as much as you can without getting too stressed.

    Find the right place to study.

    The first thing you need to do is avoid distractions (分散注意力的事物) while studying. {#blank#}2{#/blank#} You should keep away from television sets and phone calls. Get all of your study materials together, so you will not be interrupted in the middle of your session.

    Break down the tasks into smaller parts.

    When you have gotten everything ready, list the items you need to study, and arrange them across several hours or days, depending on how big your load is. As a general rule, assign (分配) at least one hour to each subject. {#blank#}3{#/blank#} By doing this, you will be able to know more easily how long you need for each topic.

    Schedule study breaks.

    When you have listed all of your tasks and made a schedule, you should arrange study breaks. {#blank#}4{#/blank#} This will give your eyes some time to rest, and yourself a chance to go to the bathroom or have some coffee. Scheduled breaks will reduce the need for you to interrupt yourself to the lowest level during the study session.

    Put your tasks in order of importance.

    {#blank#}5{#/blank#} Just in case you run out of time to study, or if you think you do not have enough time to cover all topics, you should study in an order.

A．Each break may take about 15 minutes every two hours.

B．Learn to arrange the subjects in order of importance.

C．This means going to one place that will give you peace and quiet.

D．The key to efficient studying is following the schedule strictly.

E．You can find a way to test your knowledge by having a study partner.

F．If you have a broad subject, you will need to break it down into smaller parts.

G．To make the best use of your time, you need to learn how to study efficiently(高效地).

Why is volunteering important?

    When it comes to service work, it is important to realize that the actual goal should be getting the most out of your volunteering work. {#blank#}1{#/blank#}

    Gaining new /social experiences.

    Volunteering allows students to get involved with new things and develop social and academic skills that couldn't be learned in a classroom environment. {#blank#}2{#/blank#}

    Giving back and helping others.

    Volunteers create better environments for others—they create healthier communities and they brighten lives. Jill, a senior student, had been a volunteer in her community (社区) for more than three years. {#blank#}3{#/blank#} "They always tell me how great we sound and how they wish they had taken time to learn an instrument in their youth."

    Creating connections with people.

    {#blank#}4{#/blank#} Not only does the volunteer work you do show who you are as a person, but it reflects many positive qualities that possible employers and admission officers want to see. Volunteering allows you to meet a wide variety of people from all sorts of walks of life.

    {#blank#}5{#/blank#}

    Volunteering isn't one of the most attractive jobs, but it is one of the most beneficial and uplifting (令人振奋的). It's taking some time out of your day to help others. Volunteer work makes us feel good. It builds self-confidence and lifts up the spirits.

    Some people lie all the time. However, it can be difficult to determine when they are lying to you. {#blank#}1{#/blank#}.

    Make false eye contact

    A person who is lying to you won't make eye contact with you or they make too much eye contact. If a person is lying he may feel you are watching him and he will look down at the floor or away from your eyes. Some people try to stare at you in the face in a deliberate way. {#blank#}2{#/blank#}.

    Avoid using contractions (缩略语)

    The liars will say "I did NOT notice your money", instead of "I didn't notice your money". This is an attempt by the liars to be absolutely clear what they mean. {#blank#}3{#/blank#}.

    {#blank#}4{#/blank#}

    Liars often feel uneasy, turn away from the person to whom they are speaking, blink rapidly, smile less and have pitch changes in their tone of voice. They may cross their arms which is a sign of being "closed" or trying not to reveal too much information. They could touch parts of their face, an ear or a nose or play with keys or another item that they have in their hand.

    Provide additional information without being asked for it

    {#blank#}5{#/blank#}. The result is the more complicated the story is, the less believable it will be. You will have the feeling that nothing could be further from the truth.

A. Usually, it ends up making the story a lot less believable.

B. Luckily there are always some indications that can help you recognize liars.

C. Use unusual body language.

D. Behave abruptly.

E. Liars seem to think that by telling their story in detail, you will find it more believable.

F. Liars try to talk the story with their own words using imagination.

G. In this way, they feel like making eye contact will make what they are saying more believable.

Lying awake for hours before falling asleep is a common problem. Even if you can finally fall asleep, taking too long to fall asleep can lead to too few hours of sleep altogether. {#blank#}1{#/blank#} So people having trouble falling asleep always wonder how they can sleep well. 

Parents know from experience that gentle music can help babies fall asleep. Science supports this, showing that children of all ages, from babies to elementary school children, sleep better after listening to comfortable music. Fortunately, children aren't the only ones who can benefit from gentle music before bedtime. {#blank#}2{#/blank#}

Listening to music likely improves sleep for more than one reason. Music can promote sleep directly by affecting your physiology (生理机能). {#blank#}3{#/blank#}Besides, it can also promote sleep by becoming a healthy bedtime habit. Many people can't fall asleep quickly because stressful and worrying thoughts keep them awake at night. By listening to music, the mind has something else to focus on. With time, the practice of listening to music at bedtime becomes more effective as the brain positively associates music with sleep. 

{#blank#}4{#/blank#} Studies have looked at many types of music and playlists but there isn't a clear answer about the best music for sleep. What we do know is that researchers have typically used either a self-made playlist or one that has been designed especially with sleep in mind. One of the most important things on how music affects a person's body is their own musical preferences. {#blank#}5{#/blank#} For those who don't want to design their own playlist, online music services have stepped in and usually offer playlists for sleep or relaxation.

A．It can guarantee sufficient sleep.

B．It's natural to wonder about the best type of music for sleep.

C．The quality and quantity of our sleep become poor as we age.

D．Listening to music can reduce your stress and inspire positive feelings.

E．This can have a serious effect on a person's quality of life if it continues.

F．People across age groups report better sleep quality after listening to soft music.

G．Useful personal playlists may include relaxing songs that have helped with sleep in the past.
