All whales fall into two groups, those with teeth and those without. Both beluga and dolphin belong to the suborder of toothed whales known as Odontoceti, along with porpoises, narwhals, pilot whales, killer whales and the largest toothed creature in the world, the sperm whale. Size differences among the Odontoceti are remarkable. A common porpoise will run only 4 or 5 feet in length and 300 pounds in weight; a sperm whale may be 10 times as long and 300 times as heavy. The beluga falls in between, weighing up to 2,000 pounds. And it does chirp. In fact, it makes a great variety of squeaking, whistling, and clicking sounds which have earned it the name of sea canary.

The toothless, or baleen, whales belong to the suborder of Mysticeti. This is a group of generally large whales, formerly abundant in all the oceans of the world. Though reduced by hunting, most species are still found along the coasts of the United States and Canada. All but two of the Mysticeti reach 40 feet or more at maturity, with the blue whale running up to 100 feet and tipping the scales at up to 130 tons. This whale is by far the largest creature that has ever lived on Earth, 4 times the weight of the largest dinosaur, 30 times that of an elephant.

72. With what topic is the passage mainly concerned?

A. Breeding habits of whales　　　　　　　　　　　 　 B. Differences between whales

C. Efforts to preserve whales　　　　　　　　　　 D. The intelligence of whales

73. All of the following whales belong to the suborder of Odontoceti except_______

A. narwhals　　　　　　　　 B. dolphins　　　　　 C. blue whales　　　　　　 D. pilot whales

74. Which of the following is mentioned by the author as a reason why the baleen whale population has been reduced?

A. Increased pollution of the seas　　　　　　　　　　　 B. Hunting

C. Insufficient supply of food　　　　　　　　　　　　　　　　　 D. Disease

75. According to the passage, which of the following accurately describes the relative sized of two whales?

A. The blue whale is larger than the sperm whale.

B. The beluga is larger than the blue whale.

C. The killer whale is larger than the sperm whale.

D. The porpoise is larger than the killer whale.

Ears are for hearing — everyone knows that. But for a creature called the Cuvier’s beaked whale, hearing starts in the throat (喉嚨), 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 (聲吶). 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 (構(gòu)造) called “the window for sound”. Found on the lower jaw, this structure is very thin on the outside and has a large pad (墊) 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.
【小題1】
Toothed whales look for food under the sea by ______.

A．watching the shape and size of their objectsB．diving deep into the sea
C．sending and receiving soundsD．making lots of noises
【小題2】
Researchers took X rays of two Cuvier’s beaked whales in order to ______.
A．find out why they had died and washed up on the beach
B．make a computer model of a Cuvier’s beaked whale’s head
C．make sure that sound travels through the head
D．know more about the way the whale hears
【小題3】
Which of the following describes the way taken by sound waves through a Cuvier’s beaked whale?
A．A hole in the back of the jaw → the ears → the jaw → the throat.
B． The jaw → the throat → a hole in the back of the jaw → the ears.
C． The throat → the jaw → the ears → a hole in the back of the jaw.
D．The ears → the throat → a hole in the back of the jaw → the jaw.

Which of the following is TRUE according to this passage?
A．The throat is important to the Cuvier’s beaked whale’s hearing.
B．Ships send out sound waves like a Cuvier’s beaked whale.
C．The ears are actually useless to the Cuvier’s beaked whale.
