Question: Why is it so hard for some people to apologize after they've done something wrong? I have made efforts to persuade my uncle to be nice to people that he's hurt. {#blank#}1{#/blank#} How I wish things would be better if he'd just say he's sorry and ask them to forgive him.

Answer: {#blank#}2{#/blank#} It's just easier for him to pretend nothing happened than to face the embarrassment (尴尬) of admitting he was wrong. You've probably done the same thing yourself at some time. In fact, most of us have. Furthermore, what if others won't forgive him even if he apologizes?

    {#blank#}3{#/blank#} Pride blinds us to our mistakes or faults. Or at least it makes us pay less attention to their seriousness.

    Pride also makes us unwilling to admit to others that we were wrong. Perhaps we're afraid they will look down on us if we admit it. {#blank#}4{#/blank#} 

    But others see through our pride. And things would be far better if we admitted our faults and asked for forgiveness. {#blank#}5{#/blank#} 

    Now you know why your uncle refuses to apologize, talk to him again. Help him to learn how to apologize and ask for forgiveness from others.

A. But a deeper reason is pride.

B. But he just refuses to do that.

C. We may even hope that somehow they will overlook it.

D. As a result, you would offend others and hurt their feelings.

E. There are a variety of reasons for your uncle's refusal to apologize.

F. Otherwise our pride would only hurt us and cause conflict with others.

G. One reason your uncle finds it hard to apologize could be embarrassment.

    Do you usually feel you're working hard but still can't reach your study goals? Here are some quick tips to help you study better.

Study with a partner or in groups

    Rather than living in a cave with your nose in the books all day, grab a friend from your class and study with him.{#blank#}1{#/blank#}

Step into your teacher's shoes

    Ask yourself “If I were the teacher, what would I put on the test?”You have probably experienced a lot of your teacher's tests and quizzes by now.{#blank#}2{#/blank#}Teachers have specific types of information that they want you to learn. The structure is usually the same.

Paint pictures on the paper

    You can build your knowledge structure in the form of pictures. It's harder to remember each piece of a puzzle individually than it is to recall the completed picture.{#blank#}3{#/blank#}

    A hungry brain is an ineffective one. Your brain needs the proper nutrients to keep it going. Because of this, what you eat and drink also play a huge role in how sharp your brain is. Healthy food provide nutrients to your brain cells to keep them energized.

Take breaks to relax your brain

    Your brain is like a muscle. It can be also tired if you overwork it,{#blank#}5{#/blank#}If you divide studying into 15 to 30 minutes blocks with quick breaks in between, your brain will feel refreshed, grateful and ready for the next challenge you throw at.

A. Feed your brain from time to time.

B. It needs exercise to make it stronger.

C. Relax your brain by eating and drinking.

D. You'd better learn from them for the next test.

E. It's necessary to have a long holiday and have nice food.

F. Find ways to connect what you are learning to real life or to other concepts.

G. Group studying helps you to engage and process the information more deeply

    Do you know that there's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. {#blank#}1{#/blank#}

    Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. {#blank#}2{#/blank#} —it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same," freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Sustainability

    According to a new study, the global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. {#blank#}3{#/blank#} 3D food printing could probably contribute to the solution. 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

Nutrition

    {#blank#}4{#/blank#} Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    {#blank#}5{#/blank#}

    Despite recent advancements in 3D food printing, the industry has many difficulties to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad.

A. Challenges

B. Opportunities

C. And the industry isn't stopping there.

D. Sustainability is becoming a necessity.

E. Future 3D food printers could make processed food healthier.

F. Here are some new ways to produce 3D printing.

G. Not everybody can do that.

Good Postures Benefits Health

    Unless you become a ballet dancer or a soldier—occupations where poor postures is easily noticed —{#blank#}1{#/blank#}However, if parts of your body such as the neck, shoulders or lower back start lo cry out in pain, you may find out that your postures  go wrong.

    Posture is more than just a function of the way someone stands or sits.{#blank#}2{#/blank#}The   main health risks of poor postures arc aches and pains, which can occur right away or down the road. This discomfort may start in the neck or back, but finally it may affect the hips and knees. Those who exhibit bad posture may also be less efficient, and they are more likely to be injured when they move.

    {#blank#}3{#/blank#}Physically, it can minimize the force that muscles and joints need to absorb. Moreover, it can help people appear taller and feel better about themselves. Mentally, psychology studies have suggested that people's postures in low spirits make them look less confident and competent than others.

    There are many activities in people's daily lives that can affect postures and throw the body off balance if you don't pay attention. Examples include sitting at a desk for long periods, frequently holding a phone between the ear and the shoulder and bending over a laptop.{#blank#}4{#/blank#}The body was not physically designed to stay in one position. If you go a long time without changing your position, it can start to stress your body's tissues.{#blank#}5{#/blank#}If you are concerned about having poor postures, you can turn to an expert who will show you how to do certain exercise that helps improve tight muscles.

A. you will learn the benefits of having good postures.

B. you probably don't pay much attention to your postures.

C. Regular exercise is a good way to help form good postures.

D. Keeping good postures can benefit a person's body and mind.

E. It is also a reflection of the body's strengths, weakness and overall health.

F. To make up for this, you are recommended to switch positions every 20 minutes.

G. Modem people's continually looking down at a smartphone is another typical one.

    {#blank#}1{#/blank#} While these compulsive(无法控制的) actions may appear to be irrational or pointless, and may even result in negative consequences, the individual experiencing the compulsion feels unable to stop him or herself.

    The compulsive behavior can be a physical act, like hand washing, or a mental activity, like counting objects. When an otherwise harmless behavior becomes so consuming that it negatively impacts oneself or others, it may be a symptom of obsessive-compulsive disorder (OCD)(强迫症).

    {#blank#}2{#/blank#}The former is an overwhelming desire to do something, while an addiction is a physical or chemical dependence on a substance or behavior. People with addictions will continue their addictive behavior, even when they understand that doing so is harmful to themselves and others. {#blank#}3{#/blank#}

    Unlike compulsions and addictions, which are acted out uncontrollably, habits are actions that are repeated regularly and automatically.

    Habits typically develop over time through a natural process called "habituation," during which repetitive actions that must be consciously initiated eventually become subconscious and are carried out habitually.

    While there are good habits and bad, unhealthy habits, any habit can become a compulsion or even an addiction. {#blank#}4{#/blank#} For example, the good habit of exercising regularly can become an unhealthy compulsion or addiction when done to excess.

    Common habits often develop into addictions when they result in a chemical dependency, as in the cases of smoking. The habit of having a glass of beer with dinner, for example, becomes an addiction when the desire to drink turns into a physical or emotional need to drink.

    {#blank#}5{#/blank#}While we can choose to add good, healthy habits to our routines, we can also choose to break old harmful habits.

A. A compulsion is different from an addiction.

B. It currently affects about 1 in 40 adults and 1 in 100 children in the U.S.

C. Some of these behaviors are visible actions while others are mental behaviors.

D. In other words, you really can have "too much of a good thing."

E. Compulsive behaviors are actions that a person feels "compelled" or driven to do over and over again.

F. Alcoholism, smoking, and gambling are perhaps the most common examples of addictions.

G. Of course, the key difference between a compulsive behavior and a habit is the ability to choose to do them or not.

I have worked for a local charity for many years. I volunteered there as one of the youth group leaders. The job sometimes was tiring. {#blank#}1{#/blank#} And one of our favorite activities is called "ARK night" — A couple of times a year, on a Sunday night, all kids in the charity went into our community to perform kind acts for others.

{#blank#}2{#/blank#} One group typically goes downtown and hands out sandwiches, water and bread. Another group makes posters and goes to local police and fire stations to say "Thank you". Our group often visits nursing homes and hospitals.

One time, the group I was leading left post-it notes (便利贴) with positive messages on the cars in a hospital's parking lot. The hope was that someone who was sad after visiting a patient would be cheered up by our notes. {#blank#}3{#/blank#} I made the kids write positive messages on the notes. Then we went out to put those notes on cars.

After the kids left their notes on the cars, one girl said, "We didn't see one single person tonight. How will we know our notes made a difference?" I replied, "{#blank#}4{#/blank#}" But actually I wondered about it, too. Would the notes cheer anyone up? But I had to take those kids back before 9:00 pm.

Later I got the answer. On Monday morning I found a post online by a woman. She described her bad luck over the weekend. "But then," she added, "this morning I found the nicest little note on my car. It made my day." She included a photo of the note. It was one of our notes! {#blank#}5{#/blank#}

A. Let's stay here and find out.

B. We'll just have to trust that they did.

C. The drivers were surprised by our special notes.

D. But I loved working with those little volunteers.

E. I smiled and couldn't wait to tell the kids the good news.

F. We had spent the first part of the evening preparing notes.

G. The kids are divided into small groups, with each group having a different task.
