　　Simply sitting and watching birds is a popular hobby around the world. It's fun and relaxing at the same time.

　　Many people quite enjoy just watching the birds in their garden, yard, trees and bushes from their front window. And it's even better to actually go out into the wild and watch the birds in their own natural habitats.

　　Natural habitat of course usually means going into the woods, or to remote areas. So before going on a bird watching outing, be sure you've prepared a little. First and foremost, be sure you're wearing the appropriate clothes for both the location you'll be visiting, and the climate that area is currently experiencing.

　　If you live in a warm desert area，for instance，and you plan to go up a mountain for a day of bird watching, you'll want to first find out if there's any snow on the mountain，or whether it's cold during the daylight hours.

　　You'll of course also want to be sure you have some food or snacks, and plenty of water.

　　Besides, binoculars are almost a requirement for bird watching too. They allow you to get a closeup view of any birds，nests，and chicks. Many bird lovers also enjoy having a pen or pencil, and a notebook on hand so they can take notes about the birds they've seen，or sketch them as they're watching.

　　And of course if you like pictures，you'll want to bring along a camera.

　　Last but not least, it would be helpful to have some sort of bird identification reference available. Whether you can take it with you into the woods，or you have it hanging at home，it is always quite useful in the long term.

　　5. The underlined part"binoculars"in the sixth paragraph probably refers to ________.

　　A. a pair of special glasses B. foods

　　C. tools for catching birds D. high spirits

解析：选A。词义猜测题。由后文中的They allow you to get a closeup view of any birds，nests，and chicks. 可以推断，binoculars指的是一种可以让人近距离观察鸟的仪器，所以选A。
