【推荐1】How do you feel about nature? After spending hours indoors, do you feel better when you visit your local park? Most people think that nature is good for our bodies and brains. However, humans are spending more time inside and less time outside. For example, the number of visitors to Canada's national parks is getting lower every year. And in countries such as the USA, only 10% teenagers can spend time outside every day. Many doctors feel this is a problem in the 2lst century.

As a result, some doctors are studying the connection between nature and health: one example of this is the work of Dr. Matilda in Sweden. The doctor gave people a maths test. During the test, their heart rates（心率）were fast. After the test, one group of people sat in a 3D-vitual-reality（虚拟现实）room for fifteen minutes with pictures and sounds of nature. Their heart rates were slower than people's in the other group.

The virtual touch with nature helped them feel more relaxed. Another god example of how nature is good for health comes from Canada. In Toronto, researchers studied 31,000 people living in the city. In general, they found that healthier people lived near parks.

Because of studies like these, some countries and cities want nature to be part of people's everyday life. In Dubai, for example, there are plans for a new shopping mall with a large garden so shoppers can relax outside with trees, plants and water. In Switzerland, "forest schools" are popular. Many children study their subjects in the forests and do lots of exercise outside.

And South Korea is another good example: it has new forests near its cities and around 13 million people visit these forests every year. So after building cities for so long, perhaps it's now time to start rebuilding nature.

【推荐2】Maybe you are an average student.     1     This is not necessarily so, however. Anyone can become a better student if he or she wants to. Here's how.

Plan your time carefully.

When you plan your week, you should make a list of things that you have to do.     2     First, arrange your time for eating, sleeping, dressing, etc. Then decide a good, regular time for studying. Don't forget to set aside enough time for entertainment. A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time.

Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or TV! When you sit down to study, concentrate on the subject.

Study regularly.

When you get home from school, go over your notes.     4     If you know what your teacher is going to discuss the next day, read the material. This will help you understand the next class. If you do these things regularly, the material will become more meaningful, and you will remember it longer.

Develop a good attitude about tests.

The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge.     5    

Overweight(超重) is one of the biggest health problems now. Being overweight affects(影响) more than how you look. Too much fat can kill you.

You are what you eat. Kids like snacks. Do you know any healthy snacks? One study of eating habits shows that soft drinks are the first in the snack list. Next, kids choose salty snacks, like chips. What’s more, the list is full of junk food. Finally, kids pick a healthy snack—fruit.     3    

Get outside to exercise.

Jim, a player on his school football team, had a weight problem not long time ago.     4     So his father and he started playing football for a few minutes every night. Ten minutes turned into an hour or more. In just a few years, the heavy kid became healthy and he had more friends to play with.

More TV means more fat.

More TV(or more Internet surfing, or more computer games) means more fat. Eat an apple a day, walk around the house, play with your family…     5     It will help you a lot.
