Sodas such as Coke or Pepsi are responsible for adding to health problems like tooth problems and obesity （肥胖）.So health leaders have recommended teens cut back on sugar-sweetened sodas.However，their push may have had an unplanned result.Many of the advertisements aimed at teens show fit athletes having sugar-sweetened sports drinks.They make sports drinks look like a healthy choice for teens compared to sodas.As a result，teens are turning to this kind of drink.
   Scientists at Harvard University in Massachusetts focused on teens，who are considered more likely than younger kids to buy their drjye.aiks.In 2015，22，000 high school students were surveyed，and almost 6 in 10 of them reported having at least one sports drink in the past week.That was up slightly from 2010.The Harvard study found that almost one-third of teens drank one to three sports drinks in the previous week.Just over 1 in10 reported having four to six drinks.Teens who played on sports teams were likely to have one or more sports drinks each day.Boys were more likely than girls to have the drinks，scientists found.
   The same was true for teens who watched more than two hours of television.Scientists say they are concerned because of ties between TV watching，ads，and obesity.Experts say that many children don't need a sports drink that is full of carbohydrates （碳水化合物） and sweeteners. This especially applies to children sitting in front of a TV.The better option is water or unsweetened drinks.
   "There is no reason to have carbohydrates in sports drinks unless you are in a high-level game，said Nyree Dardarian，the leader of the Center for Integrated Nutrition and Performance. "Someone on a long bike ride or in an all-day race might want to have one.If children are playing for 20 minutes，they just need water."
   There are other choices.Water and oranges would provide all of the recommended amounts of vitamin C for kids.Other ideas include flavoring water by adding fruit to it.Kids can also add a small amount of juice.

1．Animals are natural resources that people have wasted all through our history.
   Animals have been killed for their fur and feathers，for food，for sport，and simply because they were in the way.Thousands of kinds of animals have disappeared from the earth forever.Hundreds more are on the danger list today.About 170 kinds in the United States alone are considered in danger.
   Why should people care？Because we need animals.And because once they are gone，there will never be any more.
   Animals are more than beautiful or interesting or a source of food.Every animal has its place in the balance of nature.Destroying one kind of animal can create many problems.
   For example，when farmers killed large numbers of hawks（鷹），the farmers' stores of corn and grain were destroyed by mice.Why？Because hawks eat mice．With no hawks to keep down their numbers，the mice multiplied quickly.
   Luckily，some people are working to help save the animals.Some groups raise money to let people know about the problem.And they try to get the governments to pass laws protecting animals in danger.
   Quite a few countries have passed laws.These laws forbid the killing of any animal or plant on the danger list.Slowly，the number of some animals in danger is growing.

2．If you are a teenager without a job，you probably do not have much extra money.Sometimes parents will give their children a weekly pocket money for doing small housework，but it is often not enough once the children grow into teenagers and want to do things with their friends all of the time.How to make money is an important thing for teens to learn.If you're wondering how a teenager can make good money，some ideas might be：

   Some teens are good at something such as writing or photography.These teens can make money by doing things such as writing articles for newspapers or magazines or selling their photos online.
   Teens who live in a country area can earn money by helping out on farms，or they can try raising their own animals such as chickens，and selling them or their products.
