• 12．Parents can cut the chances of their children getting fat simply by keeping them longer at table.Just three minutes extra at a family mealtime could help prevent child obesity.Research found that among poor families，the extra minutes at mealtimes made great improvement of a normal weight for the youth.The factors are likely to be communication and the importance of a scheduled mealtime.
     Dr.Barbara Fiese said，"Children，whose families have a 20-minute meal over four times a week，weigh less than kids who leave the table after 15 to 17 minutes.Over time，those extra minutes per meal add up and become really powerful."
     The researchers studied 200 family mealtimes，testing the effects of factors and mealtime behaviour of families with children in primary school.They found that families，who said that shared mealtimes were an important part of family life and had special meaning for them，were less likely to have an obese child.Similarly，families，who talked more together and interacted more positively during the meal，were more likely to have healthy-weight children.
     Teaching low-income families how to make the most of family mealtimes was a wise idea.Dr.Fiese said，"This is something we can target and teach." She added，"It's also important to recognise the increasing differences of families and their sometimes complex living arrangements that may challenge their abilities to plan ahead and arrange a single time to communicate with each other."
     Families in poorer US neighbourhoods faced a lot of problems，including poor access to healthy food.But even so，regular high quality family mealtimes made a difference to the children's weight.Dr.Fiese said，"Three to four extra minutes per meal will make a healthy weight more possible."

• 13．For some people，walking or running outdoors is a great way to exercise.What may not be so great is seeing rubbish all over the ground.Well，some people are doing something about it.（1）

  "Plogging" began in Sweden.The name connects the Swedish word "plocka" which means to pick up，and the word "jogging" which means to run slowly.
      A Swedish man named Erik Ahlström，started the movement in 2016.He moved to Stockholm from a small community（社区）in northern Sweden.Each day he would ride his bike to work.He became worried about the amount of rubbish and litter he saw each day on his way to work.So，he took matters into his own hands.He began picking up the rubbish.（2）

  
     Today，plogging is an official activity，which is becoming more and more popular.People of all ages are welcome to plog.Exercise while helping your community.（3）

  It can also build closer social connections in a community.When the street looks bad and it's dirty，you're going to feel bad about the community.You may even feel less safe because of that.So if we're all doing our part and picking it up，it's very easy to help beautify it，and help build those social connection.（4）

  You get to feel some social duty when you do this.
     Along with cleaning up the environment，there may be another reason to choose plogging instead of just jogging.You may get a better workout.One fitness app，Lifesum，records one hour of plogging as burning 288 calories.（5）

  
     As can be seen，cities around the world now hold plogging events.The goal is to spread the idea that littering is not acceptable.People would think twice before dropping a garbage on the ground.
  
  A.Plogging is equal parts of exercise and community service.
  B.And that is how plogging was born!
  C.And plogging does good to your health.
  D.Usual jogging burns about 235 calories.
  E.They are plogging!
  F.There are people all around the world doing this.
  G.You get to know your neighbours.
