To wash yourself, you take a bath(洗澡) or a shower. Animals need to keep clean, too. How do animals clean themselves?

Cats lick（舔）themselves to keep their fur clean. Have you ever watched a pet cat clean itself?

Elephants take baths much as you do. But instead of jumping into the tub（浴缸）, they walk into a river or lake.

Pigs also like to roll around in water. This keeps them clean and cool. If there is no clean water, they will roll in mud（泥）on a hot day. They do this to cool off. Pigs do not really like mud. They are happier in a nice, clean pond(水池).

Bats have a funny way to keep clean. They lick their thumbs to clean their ears!

Guess how polar bears clean themselves. They use snow, of course!

Some animals take baths in dust instead of water! The wombat(毛鼻袋熊) is an Australian animal with lots of fur. To get clean, it lies down. Then it covers itself with sand!

Birds clean themselves in many ways. Sometimes they wash in water. That’s why some people put birdbaths in their yard. At other times birds take dust baths, just like wombats. Birds also use their beaks（喙）to keep their feathers clean. They use their beaks the way you use a comb.

Sometimes a bird has itchy bugs（发痒的虫子）in its feathers. Birds may use ants to help them clean off the bugs. A bird will lie down on an ant nest. Then the ants will crawl on the bird. The ants make a kind of bug spray（喷雾）on the feathers;. Then the itchy bugs die!

Birds take baths in something else besides dust and ants! Some birds take “smoke baths” They sit on chimneys. They wave their wings in the smoke!

This passage mainly tells us       .

A. why some people put birdbaths in their yard  B. why birds allow ants to crawl on their body

  To many web-building spiders, most of whom are nearly blind, the web is their essential window on the world: their means of communicating, capturing prey（猎物）, meeting mates and protecting themselves. A web-building spider without its web is like a men cast away on an island of solid rock，totally out of touch and destined to

starve to death.

    So important is the web to an orb-web spider's survival that the animal will continue to construct new webs daily even if it is being starved. For 16 days the starving spider builds completely normal webs. Then, as the animal gets scrawnier（憔悴的）， it constructs a wider-meshed web using fewer strands（线）. Such webs would only trap larger prey, which is more economical from the perspective of a starving spider.

    The spider stores energy by recycling web protein. It simply eats its own web each evening and reuses it to produce new silk. In studies with radioactively，labeled materials, it was found that 95 percent of web protein reappears in the next day' web. Most of the energy needed for web-building is used in walking over the strands as they are laid down．

    Scientists are impressed by the adaptability of the spider's highly preprogrammed brain, which is larger for its size than the brain of any other invertebrate（无脊推动物）．If web-building is interrupted, or if some of the existing strands are destroyed，the spider simply goes back to see where the web is left off and then finishes building a normal web. One spider will finish building the incomplete web of another.　

Which of the following best expresses the main ideas of the passage?

A. Secrets of Spiders' Adaptability                            B. Importance of Webs to Spiders

C. Secrets of the Spiders' Life                           D. Spiders' Highly Preprogrammed Brain

    D. Web-building spiders have good eyesight.
