There are a lot of people who are overweight all over the world. What causes obesity? If you get the gene(基因), well, probably you are going to be a few more pounds heavier compared to the rest of your classmates or friends. {#blank#}1{#/blank#} Obesity can not only make a person look heavy, and not in the usual sense of being handsome, but can also lead to serious health conditions and life-threatening diseases.

    {#blank#}2{#/blank#} Indeed, junk food has been blamed for the prevalence(流行）of obesity. It is called junk food, because hamburger, pizza and the like contain high calories. If you eat a Big Mac (a super hamburger), an order of large fries, and a large Coke, you will need to walk non-stop for six hours to burn off the calories you have gained. And don't be fooled by soft drinks, which are high in sugar and are a major cause of obesity.

    {#blank#}3{#/blank#} Popular sugary drinks, of course, include Coca Cola, Pepsi(百事) Cola, and many new brands that appear on the market every couple of days.

    {#blank#}4{#/blank#} Just one 20-ounce (about 567g) bottle of soda can have 250 calories, which are equal to more than 16 teaspoons of added sugars. Even a lemon-flavored iced tea can have 210 calories.

    {#blank#}5{#/blank#} Next time, when you are ready to eat that huge Mac and to drink that two-liter bottle of Pepsi, probably it's a good idea to give it a second thought.

A. Obesity is more common in women than men.

B. Most people don't realize how easy it is to gain weight from drink sugar-sweetened beverages(饮料)

C. When we talk about obesity, the first thought that comes to mind is: junk food.

D. The unburnt calories will put weight on you.

E. Keeping healthy is our own responsibility.

F. Because of their high content of sugar, soft drinks are also called sugary drinks.

G. However, the most common cause of obesity is eating too much, especially too much junk food.

    You must be willing to calmly accept any of these responses.If he says he does want to stop,go on with the next step.If not,they will have to be visited later when he is ready.

    Violent Games: Fun or Harmful?

    If you play lots of video games, you've probably blown a zombie(僵尸) into tiny bits. {#blank#}1{#/blank#} Many adults worry that playing such games could make children act violently in real life. Is that true?

The American Academy of Pediatrics(儿科) says that violence in any kind of media — from TV to music to video games — presents a risk to kids' health. A number of studies have shown a link between video games and aggression, including one published in JAMA Pediatrics in 2014, which found that kids who played violent video games showed an increase in aggressive thoughts and behaviors. {#blank#}2{#/blank#}

    But not all studies agree that violent games cause kids to act out. Another study replaced violent deaths with evaporation(蒸发) in a game. {#blank#}3{#/blank#} People who played the non-violent game without any training were more aggressive afterward than people who played the violent version but learned to control themselves first.

    And here's an even stranger fact: When violent video games are released, people carry out fewer violent crimes! Why? {#blank#}4{#/blank#} Steve Levitt, coauthor of the book Freakonomics, said, “If you can make video games fun enough, then kids will stop watching TV, and they'll stop going out and creating violent disorder on the street.”

What do you think? {#blank#}5{#/blank#}

A. One possible explanation: potential criminals are at home playing the new game.

B. Then, before playing the game, some people received training and others didn't.

C. More than 3,000 kids answered survey questions during a two-year period.

D. For example, thinking it's OK to hit someone you don't like.

E. Have you ever played any violent video games?

F. Do violent video games cause bad behavior?

G. Some games even pile up dead bodies.

{#blank#}3{#/blank#}Look to see if the story you are reading is on other news sites that you know and trust. If you do find it on many other sites, then it probably isn't fake, as many big news organizations try to check their sources before they publish a story.

There are other techniques that fake news uses. These include using ALL CAPS and lots of ads that pop up when you click on a link. {#blank#}4{#/blank#}If the news story makes you angry, it's probably designed to make you angry.
