Birdwatching is becoming more and more popular in many parts of the world.

Birdwatchers enjoy looking for and listening to different kinds of birds. To watch birds, all you need is a pair of binoculars, a field guide and love for birds.

If you are just starting birdwatching, buy one of the cheaper pairs of binoculars. You can choose better ones when your needs and skills grow. A field guide helps you learn about the birds’ appearances, calls and habits before birdwatching.

When you are ready, it’s best to go to the wild with someone who is more experienced. You can join a birdwatching group to learn about some beginning skills. A local bird club is ideal.

Start birdwatching in the morning, when birds are searching for food. Most of the time, you will hear bird calls from all around you, but will not see any birds easily. Look for movement in trees, and bring your binoculars to your eyes.

The most important work for a birdwatcher is to identify the birds he/she sees. A bird’s shape, size, colour and habits can help a birdwatcher identify it. When you identify a bird, don’t forget to take notes about it on your notebook.

To find more and different birds, you may wish to plan trips to birds' different living areas: forests, lakes, rivers, wetlands, etc.

When watching the birds, you should always keep in mind: respect wildlife and protect its living areas.

Toothpaste(牙膏) does more than just keep our teeth bright and white. It can be used wisely in many other ways. Here are some useful tips that can save us time and money, and leave a fresh smell-using toothpaste!

Clean a Dirty Mirror

If you want to clean a dirty bathroom mirror, try to put a bit of toothpaste on the mirror and wipe it dry. The glass can be cleaned up beautifully. And doing this can also stop the mirror from fogging. Then you can still see yourself in the mirror after taking a shower.

Remove the Unpleasant Food Smell

Have some bad food smell, like the smell of onions or fish, on your hands? You can remove it by washing your hands with toothpaste. You'll be fresh-smelling in no time.

Make Your Sports Shoes Whiter

This time, clean your sports shoes by yourself not by your mother. Wipe some toothpaste around your shoes and then clean it with a wet cloth. See? Your shoes are white as new!
