Have you ever gotten the feeling that a person you were friends with had a hidden schedule or simply couldn't care about your thoughts and opinions? Trying to tell the difference between someone who is genuine and someone who is faking (虚伪) it can be as confusing as trying to tell the difference between a work of art and a well-made copy.1. Read the advice of the following signs of fake people to determine which of your relationships is worth seriously investing in.
They only respect those in positions of power. When it comes to respect, most would agree that everyone is deserving of this sentiment. Yet, fake people have a tendency to only respect people in power. Watch out for people who aren't respectful of everyone around them.2.
3. Only those who lack real quality feel the need to criticize others to keep up appearances. Sincere individuals would rather admire and praise others, while fakers may be quick to put others down in name of making themselves look better.
They make promises they can't keep. A genuine person will do their best to live up to promises and commitments, but a fake person may talk the talk without walking the walk.4.
They're only nice if there's something in it for them.5. In comparison, genuine people are just that genuine. They're nice and helpful no matter what circumstances.
Keep an eye out for these signs of fake people and make room for more meaningful, genuine relationships in your life.
A.If not, they may be faking it.
B.They work hard to build any relationship.
C.They put others down in order to look good.
D.But thanks to some advice, the former doesn't have to be.
E.In comparison, a genuine person knows when to let others shine.
F.A fake person is one who only shows kindness when it benefits them.
G.Fake people easily make commitments, but rarely follow through on them.
Food companies engineer junk food to make it addictive. They label their products to make them seem much healthier than they are. Their advertisements target children. All of this is according to a news report read recently by students in a Texas middle school. They were taking part in an experiment run by the University of Chicago and the University of Texas. “I don't understand how this is even legal, ” said a girl who took part in the study.
Researchers had students learn about food-industry advertising strategies. They wanted to know if learning about them would change how kids feel about junk food. All over the world, kids are eating more foods that are high in salt, sugar, and fat. That is partly the result of clever ads that make junk food irresistible. Christopher J. Bryan led the study. He says that when kids question the motives behind junk food ads, they feel like they're fighting injustice. The reward is knowing they are doing the right thing.
Junk food has been linked to health problems such as heart disease, obesity, and diabetes，But in 2018，food companies spent nearly $9 billion TV ads selling unhealthy fare. Companies use varying strategies. An ad with cartoon characters may make chips seen fun to eat. A professional athlete enjoying a sugary drink may make it look cool. Advertisers know that if kids want a product, they'll annoy their parents to buy it. Even parents don't notice the power of ads. By the time they are adults they have been used to junk-food advertising. They just don't see it.
In the Texas study, Bryan had students view ads on iPad. Their job was to write or draw on the screen, to make each ad's message true. For example, a McDonald's ad showed a Big Mac (巨无霸) and the words “The thing you want when you order salad. ” To the end of the sentence, a student added “should be salad”.
Three months after analyzing ads, students were still choosing healthier snacks: milk instead of sugary juices, fruit over cookies. Kids are becoming conscious of themselves as agents in the world. They see a chance to make the world a better place.
1.What is the purpose of the experiment?
A.To survey what snacks children like best. B.To guide children against unhealthy food.
C.To find ways to make junk food healthy. D.To teach children how to pick out legal food.
2.How do children feel about junk food advertisements after the experiment?
A.Cool. B.Legal.
C.Funny. D.Misleading.
3.Why are parents unaware of the harm of junk food advertisements?
A.Parents have never seen such junk food advertisements.
B.Advertisements have blinded them since they were young.
C.The food industry has special advertising strategies for parents.
D.Parents have to agree with their children about the junk food.
4.How did students conduct the experiment?
A.By correcting unreal advertisements. B.By offering suggestions to food industry.
C.By making up their own advertisements. D.By studying food industry advertising strategies.
In today's world, most workers are highly specialized, but this specialization can come at a cost——especially for those on the wrong team. New research by Harvard's Growth Lab uncovers the importance of teams and coworkers when it comes to one's productivity, earning potential, and stays of employment. The research analyzed administrative data on the 9 million inhabitants of Sweden. It found that to earn high wages and returns on education, workers must find coworkers who complement, but not substitute them.
The research offers a tool to assess the right and wrong coworkers in fields of expertise. The right coworkers are those with sills you lack, yet needed to complete a team. The wrong coworkers are those who have the same skill set as you and eventually lower your value to the employer. For example, those with a degree in architecture are best assisted by workers with engineering, construction, or surveying degrees, and negatively impacted by those with landscape or interior design degrees.
“We tend to think of sills as something personal that individuals can market to a company, ” said Frank Neffke, Growth Lab Research Director “However, this vision of sills is too simplistic. One person's sills connect to another person's sills, etc. ,and the better these connections are, the more productive workers will be, and the more they will earn” Neffke adds that the benefits of working with complementary coworkers are not the same for all workers. Those with higher levels of education seem to benefit much more from working in complementary teams than workers with lower levels. Over the past 20 years, workers with college degrees or higher have been increasingly able to find better matching coworkers.
Complementary also drives careers. The research shows that people tend to stay longer in organizations with many complementary workers and tend to leave those with many workers who substitute them. These results hold true for up to 20 years of one's career.
The research also supports several well-known facts, such as cities and large firms pay higher wages. Workers are more likely to find better fitting teams in cities, and large firms often allow workers to specialize.
1.Which group of workers can make up the best team?
A.Those who can substitute each other. B.Those who come from the same place.
C.Those who are expert in the same field. D.Those who have the complementary sill
2.Who may be the best complementary coworker for an architect?
A.A landscaper. B.A house agent.
C.A constructor. D.Another architect.
3.Employers think more of their staff’s________.
A.dependence relationship B.struggling spirit
C.physical quality D.educational level
4.What can be the best title of the text?
A.What workers your employer need most
B.How coworkers impact the value of your skills
C.How coworkers get higher wages and a long-term job
D.How complementarity improves your mental potential
A year ago I lost my wonderful friend and colleague Rachael Bland. She died at the age of just 40, two years after being diagnosed with breast cancer.
Her death knocked me for six. I knew it was coming and we had talked about it—but nothing prepared me for actually not having her in my life every day. The thing was, while we only knew each other for a short period of time, she had a huge impact on me. When I got diagnosed with stage 4 lung cancer, I made a whole new group of friends. Rachael was up there with the best of them. She understood exactly what I was going through, she shared my fears and was always there at 3 am to reassure me. She was my rock.
After Rachael died, I had a nervous breakdown. I hit numerous brick walls in the weeks and months that followed. My cancer was progressing and I fell into a dark place. I pushed it away but ignored the terror of it all and inevitably it all came crashing down around me. Great Sorrow hit me when I least expected. Her death felt like a bad dream. The emotional bit aside, one of the things I found really hard was to actually accept she died.
Rachael hoped that by starting the conversation around cancer, she could help other women avoid getting cancer too. It was her absolute determination and bravery at helping to break down taboos (禁忌) that will live on for generations to come.
Rachael showed me how to live with cancer. Even in her darkest days she was determined to show that cancer didn’t get to take over. She helped remind me to get busy living with cancer rather than worry about dying of it. She was in the bottom of my heart forever.
1.What does the underlined sentence in Paragraph 2 mean?
A.I was beaten six times.
B.Her death gave me the strength.
C.She was knocked down and died.
D.Her death made me very shocked.
2.Why did the author hit the brick walls?
A.She wanted to end up her life.
B.She couldn’t stand the pain of cancer.
C.She had been suffering from nightmares.
D.She was too sorrowful to accept Rachael’s death.
3.What is Rachael’s wish?
A.To help women fight against fear.
B.To assess women’s conversational skills.
C.To prevent other women from getting cancer.
D.To inspire sick people to hope for their future.
4.Which of the following best describes Rachael?
A.Optimistic. B.Weak.
C.Humorous. D.Demanding.
