Read the following interview with Dr John Bass, an international shark(鲨鱼) specialist who has spent many years studying sharks:

First of all, doctor, are all sharks dangerous?

　　No, they aren't. There are about 250 different kinds of sharks, but fewer than 30 of them are dangerous to humans. Certain sharks are very aggressive (好斗的) and we should fear them, but the danger of shark attacks is much lower than most people think.

　　So which sharks are dangerous?

　　The Great White shark is the most dangerous. Then there is the Tiger shark, which other sharks are afraid of, and the Blue shark. Both of them are very fast and dangerous.

　　Which are the biggest and smallest sharks?

　　The Whale shark is the biggest shark in the world. It grows up to 15 m in length and weighs as much as six large cars. The smallest shark, which is found near Japan, could fit into the palm of your hand because it is only 15-20 cm long.

　　Do all sharks have teeth ?

　　Yes, they do. Most sharks have hundreds, sometimes even thousands, of sharp teeth. These are arranged in rows of four or more. They fit quite loosely in the jaw. When the front ones break off or fall out, spare teeth move forwards from the rows behind: Sharks get a new set of teeth every two weeks. In 10 years, a Tiger may lose as many as 24,000 teeth!

　　That's lots of teeth! What kind of food do sharks eat?

　　Most sharks feed on small fish, and they keep the oceans healthy by eating sick and injured fish. However, hungry sharks will eat almost anything, including smaller sharks and even rubbish. Inside one Tiger shark which was found, there was a tin can, a bicycle tyre , a leather wallet and an alarm clock!

　　And how do sharks find their food, doctor?

　　A shark's sense of smell is excellent. It will follow the smell of blood across thousands of metres of ocean. They also see well, and they have good hearing. Sharks can feel movement in water very easily too, and it is possible for them to feel a fish moving as far as 30 m away.

22. Most types of sharks are _______.　

　　A. dangerous killers B. not dangerous

　　C. afraid of people D. found in Japan

23. A shark's best sense which helps it most in finding food is its sense of ________.

　　A. taste B. sight C. smell D. hearing

24. Sharks are helpful to us as ______.　　

　　A. ocean cleaners B. small shark feeders

　　C. big eaters D. fish hunters

25. Choose the best title for this passage _______.　　

　　A. Sharks ― Our Friends B. Sharks ― The Killers

　　C. Sharks ― The Figures D. Sharks ― The Facts

阅读下列短文，从每题所给的四个选项(A、B、C和D)中。

　　On the Australian coat of arms the Emu and the Kangaroo were selected as symbols of Australia to represent the country progress because they are always moving forward and never move backwards．

　　The Emu is a large flightless bird．They stand to be 1.5 to 2 metres tall, and on average weight 36 kg．They have 3 toes, and long legs which allows them to run extremely fast．In this species, the female is larger than the male．

　　The Emu feed on grass, leaves and small insects．They live all over Australia in grasslands．

　　The female lays up to 20 eggs, which are large and are soft dark green in colour．These eggs are often prized not only by humans for decoration pieces, but by animals as a food source．The male hatches the eggs for a period of 7-8 weeks, and does not leave the nest for this period．When the eggs hatch, the male emu looks after the hatchlings for another six months．

　　The Emu is the world's third largest bird．The Ostrich and the Cassowary take the top positions．The nest of an Emu can be up to 1.5 metres wide!

　　Kangaroos are the largest marsupial(有袋)mammals．Kangaroo moves by hopping on its hind legs using its tail for steering and balancing while hopping at speed up to 60kmh．When kangaroo is moving slowly the tail is used as an extra leg and supports the kangaroo when it is standing on its hind legs．Most kangaroos can only move both back legs together and not one at a time．

　　Kangaroos are found in Australia, Tasmania, and New Guinea．They eat grass, young shoots and leaves．Kangaroos need very little water to survive and are capable of going for months without drinking at all．

　　A male kangaroo is called a buck．It is also commonly called a "boomer" or an "old man"．A female kangaroo is called a doe, or a flyer．A baby kangaroo is called a joey．

　　Kangaroos have good eyesight but only respond to moving objects．They have excellent hearing and can turn their large ears in all directions to pick up sounds．

　　Kangaroos are social animals that live in groups or "mobs" of at least two or three individuals and up to 100 kangaroos．
