Humpback whales
|
Humpback whales are sometimes called performers of the ocean. This is because they can make impressive movements when they dive. The name “humpback”, which is the common name for this whale, refers to the typical curve shape the whale’s back forms as it dives. Sometimes the humpback will dive with a fantastic movement, known as a breach. During breaching the whale uses its powerful tail flukes to lift nearly two-thirds of its body out of the water in a giant leap. A breach might also include a sideways twist with fins stretched out like wings, as the whale reaches the height of the breach. A humpback whale breathes air at the surface of the water through two blowholes which are located near the top of the head. It blows a double stream of water that can rise up to 4 meters above the water. The humpback has a small dorsal fin located towards the tail flukes about two-thirds of the way down its back. Other distinguishing features include large pectoral fins, which may be up to a third of the body length, and unique black, and white spots on the underside of the tail flukes. These markings are like fingerprints: no two are the same. Humpback whales live in large groups. They communicate with each other through complex “songs”. |
Quick Facts |

Size: |
14m~18m in length 30~50 tons in weight |

Living environment: |
Open ocean and shallow coastline waters |

Migration: |
From warm tropical (热带的) waters, where they breed, to cold polar waters, where they eat. |

Diet: |
Shellfish, plants and fish of small size |

Sometimes in groups, in which several whales form a circle under the water, blowing bubbles that form a “net” around a school of fish. The fish are then forced up to the surface in a concentrated mass. |

Pectoral fin
Humpback whales are sometimes called performers of
the ocean. This is because they can make impressive
movements when they dive. The name “humpback”, which
is the common name for this whale, refers to the typical
curve shape the whale’s back forms as it dives.
Sometimes the humpback will dive with a fantastic
movement known as a breach. During breaching the whale
uses its powerful tail flukes to lift nearly two-thirds of its
body out of the water in a giant leap. A breach might also
include a sideways twist with fins stretched out like wings,
as the whale reaches the height of the breach.
A humpback whale breathes air at the surface of the
Water through two blowholes which are located near the top
of the head. It blows a double stream of water that can rise
up to 4 meters above the water.
The humpback has a small dorsal fin located towards
the tail flukes about two-thirds of the way down its back.
other distinguishing features include large pectoral fins,
which may be up to a third of the body length, and unique
black and white spots on the underside of the tail flukes.
These markings are like fingerprints: no two are the same.
Humpback whales live in large groups. They
communicate with each other through complex “songs”.

A. cannot survive in waters near the shore B. doesn’t live in the same waters all the time
C. lives mainly on underwater plants D. prefers t work alone when hunting food
70. To make a breach, a humpback whale must _____
A. use its tail flukes to leap out of the water B. twist its body sideways t jump high
C. blow two streams of water D. communicate with a group of humpbacks

阅读下列短文，从每题所给的四个选项中选出最佳选项。
Every animals is a living radiator (散热器)--heat formed in its cells and given off through its skin. Warm blooded animals keep a normal temperature by continuously replacing lost surface heat: smaller animals, which have more skin for every ounce of body weight, must produce heat faster than bigger ones. Because smaller animals burn fuels faster, scientists say they live faster. The speed at which an animal lives is determined by measuring the rate at which it uses oxygen. A chicken, for example, uses one-half cubic centimeters of oxygen every hour for each gram it weighs. The tiny shrew-mouse used four cubic centimeters of oxygen every hour for each gram it weighs. Because it uses oxygen eight times as fast, it is said that the shrew-mouse is living eight times as fast as the chicken. The smallest of the warm-blooded animals, the humming-bird, lives a hundred times as fast as an elephant. There is a limit to how small a warm-blooded animal can be. A mammal or bird that weighs only two and a half grams would starve to death. It would burn up its food too rapidly and would not he able to eat fast enough to supply itself more fuel.
1．The passage says that every animal is a living radiator because it _____.
[ ]
A．produces heat in its body cells
B．burns fuel to produce heat
C．sends out heat through its skin
D．takes in oxygen for burning fuel
2．Small animals are said to live faster than big ones because they _____.
[ ]
A．have more skin for their weight
B．replace lost heat faster
C．burn fuel faster than big ones
D．keep a higher body temperature
3．The amount of oxygen an animal uses depends on _____.
[ ]
A．the heat the body produces
B．the food it eats
C．its size and shape
D．the length of time it lives
4．According to the passage, which of the following inferences is possibly right?
[ ]
A．There is no limit as to how large a warm-blooded animal can be.
B．The humming-bird lives faster than any other warm-blooded animals.
C．Small animals have less skin for their body weight than large ones.
D．The humming-bird is the smallest of the warm-blooded animals.
