In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front of us.

Studies have shown. for instance. that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual cues, like plate size and lighting, have been shown to affect portion size and consumption.

A new study suggested that our shot-term memory also may play a role in appetite. Several hours after a meal, people’s hunger levels were predicted not by how much they’d eaten but rather by how much food they’d seen in front of them—in other words, how much they remembered eating.

This difference suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal. says Jeffrey M. Brunstrom, a professor of experimental psychology at the University of Bristol.

“Hunger isn’t controlled solely by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal.” Brunstrom says. “This shows that the relationship between hunger and food intake is more complex than we thought.”

These findings echo earlier research that suggests our perception of food can sometimes trick our body’s response to the food itself. In a 2011 study, for instance, people who drank the same 380-calorie milkshake on two separate occasions produced different levels of hunger-related hormones, depending on whether the shake’s label said it contained 620 or 140 calories. Moreover, the participants reported feeling fuller when they thought they’d consumed a higher-calorie shake.

What does this means for our eating habits? Although it hardly seems practical to trick ourselves in to eating less, the new findings do highlight the benefits of focusing on our food avoiding TV and multitasking while eating.

1. which of the following affects our appetite and food intake according to the author?
A.When we eat our meals.
B.How fast we eat our meals.
C.What ingredients the food contains.
D.How we perceive the food we eat.
2. What would happen at meal time if you remembered eating a lot in the previous meal?
A.You would not feel so hungry.
B.You would have a good appetite.
C.You would not feel like eating at all.
D.You would be more particular about food.
3. Which of the following works best if we plan to control our appetite?
A.Picking dishes of the right size.
B.Tricking ourselves into eating less.
C.Choosing food with fewer calories.
D.Concentrating on food while eating.
4. What is the main idea of the passage?
A.Good eating habits will contribute to our health.
B.Psychological factors influence our hunger levels.
C.Eating distractions often affect our food digestion.

【推荐1】A Way Out of Social Anxiety: Volunteering and Acts of Kindness

As a socially anxious introvert (内向的人), I can prove the benefits of serving others through volunteering in my community.

A volunteer job doesn’t need to require stepping into a busy room full of 100 people at a school or hospital.     1     This kind of work is much more suitable and agreeable for introverts.

    2     When I help elders or people with disabilities who are more isolated and lonelier than I am, I feel my nervousness and self-consciousness disappear. My social awkwardness loses its grip on me when I’m focused on helping someone else rather than myself or my social performance. Unlike showing up at a job interview, business meeting, or speaking engagement, working as a volunteer with people in need takes the spotlight away from being measured or judged.     3    

Social scientists have an suitable name   for stressful social situations where we need to perform and would likely be judged or evaluated. Any time we are in evaluative situations where we are judged by others, we face this social-evaluative threat and endure a sudden rush of stress hormones that increase anxiety. When we are in situations where we offer acts of kindness or help others, however, we tend to feel less judged by others.     4     Neuroscientists have studied the warm glow of doing good that makes us feel good.

“Kindness may help socially anxious people,” says Dr. Lynn Alden, a psychology professor at the University of British Columbia.     5     She found that acts of kindness may help to count er the socially anxious person s fear of negative evaluation by promoting more positive perceptions and expectations of how other people will respond.

A.Some people are naturally reserved while others are rather outgoing.
B.Indeed, my own act of kindness has always been a sure bet to bring me out of my shell.
C.In social anxiety disorder, fear and anxiety lead to avoidance which can disrupt our life.
D.When I am giving my free time to help others, I feel truly liberated in my mission to serve.
E.Instead, my volunteer service consists of quiet one-on-one visits with isolated older adults.
F.These situations do not pose such a social-evaluative threat, but instead, calms and soothes us.
G.She and her colleagues conducted a study with 115 undergraduates who had reported high levels of social anxiety.

【推荐2】

A few years ago, I read about an eight­year­old girl who studied elephant poaching (偷猎) in school and made a poster for her local grocery store. The slogan read, “Save the elephants. Don’t buy Ivory Soap, or they will die out.”What the girl had done taught me a lesson. Since then, I have looked at eight­year­olds in a different way. As an environmental educator, I used to teach eight­year­olds about the harm of elephant poaching, rainforest destruction, and global warming. I had a degree in natural science — but not in child development. What did I think I was accomplishing by putting my environmental concerns on the shoulders of kids who still believe in fairy tales (童话故事)?

Kids develop the fear of nature when their primary contact with the natural world is hearing bad news about the environment. If I wanted to inspire conservation action, I needed to change my ways, but how? I came across some research by psychologist Louise Chawla. She wanted to know what had gone on in the childhoods of adults who are good environmental citizens. She found two things most common.They had free time to explore the rivers or woods down the street, and they had an adult in their lives who was enthusiastic about the natural world. I understand now that what turned me into a good person today was a childhood spent playing in the field and having a Dad who knew that finding a lobster (龙虾) under a rock was better than finding treasure.

So that’s what I was doing when I was eight years old — looking under rocks, climbing trees, and picking wild flowers. I didn’t know a thing about the Clean Air Act that was being debated in congress at that time. I didn’t hear a lot of environmental problems. But I built a relationship with nature and I grew up to care. Now I treat my own kids like the child I was. My kids turn off the water when they brush their teeth and turn off the lights when they leave a room.

1. What can be inferred from the first two paragraphs?
A.The author felt very proud of herself.
B.The author took action to save the elephants.
C.The author thought her teaching was a failure.
D.The author doubted the natural science.
2. How do children react when learning about environmental problems?
A.They tend to ignore the problems.
B.They become scared of nature.
C.They hate to learn natural science.
D.They want to help solve the problems.
3. Why does the author mention the research?
A.In order to show how to have a happy childhood.
B.In order to show what the best way to get close to nature is.
C.In order to show how to change the children’s bad behavior.
D.In order to show what makes children care about the environment.
4. What is mainly discussed in the passage?
A.The harm of hunting animals.
B.The causes of environmental problems.
C.The importance of encouraging kids to protect nature.
D.The right methods of developing children’s idea of nature.

文章大意:本文是一篇说明文。文章介绍了早恋可能会给年轻人带来压力,并导致抑郁,建议年轻人如何避免这样的问题

【推荐3】A new study of 8,000 young people in the Journal of Health and Social Behavior shows that although love can make adults live healthily and happily, it is a bad thing for young people. Puppy love (早恋) may bring stress for young people and can lead to depression. The study shows that girls become more depressed than boys, and younger girls are the worst of all.

The possible reason for the connection between love and higher risk of depression for girls is “loss of self”. According to the study, even though boys would say “lose themselves in a romantic relationship”, this “loss of self” is much more likely to lead to depression when it happens to girls. Young girls who have romantic relationships usually like hiding their feelings and opinions. They won’t tell that to their parents.

Dr Marian Kaufman, an expert on young people problems, says 15% to 20% young people will have depression during their growing. Trying romance often causes the depression. She advises kids not to jump into romance too early. During growing up, it is important for young people to build strong friendships and a strong sense of self. She also suggests the parents should encourage their kids to keep close to their friends, attend more interesting school activities and spend enough time with family.

Parents should watch for signs of depression — eating or mood changes — and if they see signs from their daughters or sons, they need to give help. The good news is that the connection between romance and depression seems to become weak with age. Love will always make us feel young, but only maturity (成熟) gives us a chance to avoid its bad side effects.

1. Which of the following is more likely to have depression?
A.Young people who have a strong sense of selfishness.
B.Young girls who always hide their feelings and opinions.
C.Young boys whose parents watch for their behavior.
D.Careless parents whose children are deep in love.
2. What can be inferred from the passage?
A.The older a woman is, the less likely she seems to lose herself in romance.
B.Lacking love can lead young people to grow up more quickly.
C.Early love makes young people keep close to their friends and parents.
D.Parents should help their children to be aware of the signs of depression.
3. What’s the author’s attitude towards puppy love?
A.Confused.B.Disinterested.C.Scared.D.Disapproving.
4. What’s the main idea of the passage?
A.Puppy love may bring young people depression.
B.Parents should forbid their children’s love.
C.Romance is a two-edged sword for adults.
D.Romance is good for young people.
