Ears are for hearing — everyone knows that. But for a creature called the Cuvier’s beaked whale, hearing starts in the throat (喉咙), a new study found.
The observation might help explain how all whales hear. The work might also help scientists understand how animals are affected by underwater sonar (声呐). This sonar, used by some ships, sends out sound waves to locate underwater objects.
The Cuvier’s beaked whale is a so-called toothed whale. Toothed whales dive deep into the ocean in search of food. As the whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to “see” the shape, size, and location of objects, even when they’re 1,000 meters under the sea, where it is totally dark.
To better understand how the whale hears, researchers from San Diego State University in California took X rays of two Cuvier’s beaked whales. The whales had died and washed up on the beach.
Ted Cranford and his colleagues used the images to make a computer model of a Cuvier’s beaked whale’s head. Then, they modeled the process of sound traveling through the head.
The researchers knew that some sounds get to the ears of a toothed whale through a structure (构造) called “the window for sound”. Found on the lower jaw, this structure is very thin on the outside and has a large pad (垫) of fat on the inside.
When the researchers used their computer model to work out how sound waves travel in the whale’s head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal’s jaw. From there, sound waves move through the throat, into a hole in the back of the jaw, and finally to the pad of fat near the animal’s ears.

Everyone knows that fish is good for health. 1. But it seems that many people don’t cook fish at home. Americans eat only about fifteen pounds of fish per person per year, but we eat twice as much fish in restaurants as at home. Buying, storing, and cooking fish isn’t difficult. 2. This text is about how to buy and cook fish in an easy way.
3. Fresh fish should smell sweet: you should feel that you’re standing at the ocean’s edge. Any fishy or strong smell means the fish isn’t fresh. 4. When you have bought a fish and arrive home, you’d better store the fish in the refrigerator if you don’t cook it immediately, but fresh fish should be stored in your fridge for only a day or two. Frozen fish isn’t as tasty as the fresh one.
There are many common methods used to cook fish. 5. First, lean it and season it with your choice of spices. Put the whole fish on a plate and steam it in a steam pot for 8 to 10 minutes if it weighs about one pound. (A larger one will take more time). Then, it’s ready to serve.
A. Do not buy it.
B. This is how you can do it.
C. The easiest is to steam it.
D. The fish will go bad within hours.
E. It just requires a little knowledge.
F. When buying fish, you should first smell it.
G. The fats in fish are thought to help prevent heart disease.

How to Care for Your Ears?
Ears not only let us hear, but they also play a role in maintaining our balance, which is vital to our ability to function in daily life. Yet, we ignore them. We can't even see our ears, except in a mirror. We take it for granted what they do for us day in and day out—until we notice something wrong, such as when an earache strikes or when we start having to ask people to repeat what they say.1.
◆Clean your ear with a washcloth—covered finger only.
Never put anything inside your ear canal, including cotton swabs(药签).2.
◆Leave earwax(耳垢)alone.
Wax is your ear's way of eliminating(消除)anything foreign that gets into the ear canal.3.If you find you have too much earwax, use a few drops of earwax remover in the canal. After a few minutes, wash the ear with warm water.
◆Avoid noisy places.
Rock concerts and construction sites are just a few places that frequently have noise levels that can damage hearing. Any place where you have to shout to be heard should be avoided.
◆4.
Be careful not to play MP3 too loud, especially if using earphone.
◆Be careful with illness and medications.
Respiratory(呼吸的)illnesses should be treated to avoid their spread to the ears. Certain medications can damage hearing, so follow the directions carefully before taking them.
See your doctor if you suffer from sudden hearing loss or hear noises in your head.5.
A. Turn the volume(音量) down.
B. Avoid using earphones while listening to MP3.
C. In such case, go to see a doctor as soon as possible.
D. This article will show you how to care for your ears.
E. Most people don't need to clean wax out of their ears.
F. Your ear canal is very narrow and a swab can damage it.
G. These can be symptoms of a serious illness which needs to be treated.
