For some students, getting better grades can seem like an impossible task sometimes. With the challenges(挑战) of school, just paying attention in class or studying hard isn’t always enough. But what if there were other ways for students to improve their grades? For parents and students who have ever wondered if this is possible, now you can rest easy. Research suggests that a person who likes doing activities can improve their grades.

Scientists think that those students who are active are not just exercising their bodies, but also exercising their brains(大脑). In turn, they can be able to improve their grades at school.

In the most recent study, researchers found that when children played for half an hour each day, they were better at organizing(组织) their schoolwork as well as doing project work and learning traditionally “difficult” subjects, such as maths.

What does this mean for children who aren’t active? Researchers think that if kids don’t get enough activities, they are going to be at a disadvantage when it comes to school performance.

In the research experiment, a group of children skipped with ropes(跳绳), played basketball and did a number of other games or exercises. Another group of children didn’t do any activities. They took part in testing both before experiment and after the experiment. Testing was mainly for maths and reading skills. Results showed that the children in the activity group did better on the tests than those who had no activity.

All work and no play will not only make Jack a dull(迟钝的) boy, but will also negatively(消极地) affect his grades in school, according to a new study published in the Journal of Pediatrics.

Parents complain(抱怨) children today are actually less active and they always worry about their grades. Dr. Belton, an expert, said, “If you’d like to see your kids do better in school, have them close their books, set down their pencils and go outside to play.”

Did you know that each day one person in the US throws away 4.4 pounds of rubbish? Almost every month, we throw away our own rubbish in packaging alone. Packaging ( including boxes, bags, etc) comes to our homes with the things we have bought. Several weeks ago, the TV news said that in a city in Italy, tons of rubbish were piled up in the streets, and the smell was rather terrible. What can we do to help? We should get to know the following Rs.

To reduce means to make less rubbish That is one of the first things we all should do for the environment. Reduce your rubbish by doing things like packing your lunch in reusable containers(可再利用的容器),taking smaller potions(份)at dinner so you don't waste food when you have had enough, writing on both sides of paper, and using less water when taking a shower.

To reuse is to use things again. Think about the bags you get from the store. They can be reused to carry your lunch, to hold your rubbish, or to collect used cans. You can even take them back to the store the next time to carry your things instead of getting a new bag!

Recycling is an important part of keeping our planet clean and green. It can also save energy. Be sure that you don't throw things in the rubbish that can be recycled to make something else. Paper, plastic, cans and bottles can all be recycled, but food, electrical waste and mobile phones can't. When you are not sure whether something can be recycled, go to your parents and teachers for advice.

Follow the three Rs, and every one of us can do something to save the Earth. It is also the best way to save ourselves.
