Dolphins are interesting animals and researchers find them interesting to watch. They don’t have hands, but can use tools to solve problems, just like us. Scientists have observed a dolphin trying to get a shy eel(鳝鱼) to come out of its hole by poking(捅)it with a dead fish. Many species of dolphin live in large societies. They have many different relationships and need a good communication system; they use a variety of sounds to communicate with each other.
There is currently no evidence that dolphins have a language of their own. But scientists still have a lot to find out about these animals and so there are certain to be a few surprises in the future.
At Kewalo Basin Marine Laboratory in Hawaii, the dolphin team have developed a sign langue to communicate with the dolphins, and the results are amazing. Not only do the dolphins understand the meaning of individual words, they also understand the significance of word order in a sentence. For example, when they were asked to ‘touch the ball with your tail and then jump over it’ they generally responded correctly and straight away, which showed that they understood the langue.
Most mammals seem to enjoy play—but dolphins seems to like making their games as challenging as possible. On a beautiful day in 1997, researchers working at a beach, off the southern coast of Brazil, observed a little dog going into the sea and swimming towards the dolphins. To their surprise, the dolphins approached the dog and then started throwing it into the air. The dog seemed to enjoy the ‘game’ and continued playing with the dolphins for more than an hour. From then on, different dogs were seem trying to interact with the dolphins.
Dolphins live in a very different world to ourselves, but they are very good at our ‘intelligence tests’. For example, they will jump out of the water when they hear a whistle noise. They do this because they will get a fish as a reward. There is still much to learn about these flexible(灵活的)problem-solvers, but from the evidence so far, it would seem as though dolphins are very intelligent.

Sydney – A shark savaged a schoolboy’s leg while he was surfing with his father at a beach in Sydney on February 23．it was the third shark attack along the coast of Australia’s largest city in a month．
The 15 – year – old boy and his father were in the water off Avalon, on Sydney’s northern beaches, around dawn when he was attacked．The city’s beaches are packed with locals and tourists during the summer months．
“The father heard a scream and turned to see his son trashing （扭动） about in the water,” police said．“Fortunately, the shark swam away and the boy was helped to shore by his father．”
Lifesaving Club spokesman Nick Miller: “It got him around the top of his left leg and the father came and dragged him out of water．” He said the boy was bleeding heavily when he was brought to shore．“There was a lot of pain, as you can imagine”．The teenager was airlifted to hospital for treatment for leg injuries．
Police said the bites “cut through to the bone”, but the boy did not appear to have sustained any fractures （骨折）．He was in a stable condition now．
Several beaches were closed after the attack．Water police and lifeguards were searching for the shark, while police hoped to identify its species by the shape of the bite marks．But they said it was too early to say what type of shark attacked the boy．“I don’t even know if he saw it,” Miller said．
Many shark species live in the waters off Sydney’s beaches, but attacks on humans are still relatively rare．However, there were two attacks on successive days earlier this month, one on a navy diver in Sydney harbor, not far from the famous Opera House, and the other on a surfer at the city’s world – famous Bondi beach．
Fishermen say shark numbers are on the rise．There is a ban on commercial fishing in the harbor, which has increased fish stocks．Marine experts also claim environmental protection has created a cleaner environment, attracting sharks closer to shore as they chase fish．Many shark species, including the Great White – the man – eater made famous in Steven Spielberg’s Jaws – are protected in Australian waters．

Lakes, ponds, and beaches mean summer fun and cool relaxation from hot weather. But water also can be dangerous for kids if you don't take great care. Nearly 1,000 kids die each year by drowning.

Here are some tips to keep your kids safe in the water:

At the Lake or Pond

·Don't let little kids swim alone without adult supervision— lakes or ponds may be shallow near the bank and are suddenly deep sharply further out from shore.

·Ponds and lakes may hide jagged rocks, broken glass, or rubbish.

·Make sure kids wear foot protection; even in the water, they should wear socks or water shoes.

·Watch out for weeds and grass in the water that could trap a leg or arm.

·Most boating accidents, particularly among teenagers, are related to alcohol(饮酒). Be sure teens know about the dangers of alcohol, on and off the water.

At the Beach

·Teach kids to always swim when and where a lifeguard is on duty. Unlike the calm waters of a swimming pool, the beach has special dangers like currents and tides(暗流). Check with the lifeguard when you arrive to find out about the water conditions.

·Tell kids never to stand with their back to the water because a sudden wave can easily knock a child over.

·Teach kids that if they're caught in a dangerous wave, they should swim parallel（顺行地） to the shore or should tread （踩）water and call for a lifeguard's help.

Whether at the lake or at the beach, teach your child to get out of the water during bad weather, especially lightning.

1.Which is the right behavior when swimming at the beach?

A．Go off the water without a lifeguard on duty

B．Go on swimming in a heavy rain

C．Go off the water before checking the water conditions

D．Call for help if caught in a dangerous wave

2.A child should_________ at a lake.

A．swim on his/her own

B．be careful about weeds and grass

C．swim without shoes on

D．drink only a little wine

3.Swimming at a beach is more dangerous than in a pool because .

A．there are no lifeguards at a beach

B．there are currents and tides at a beach

C．the waters of a beach are more calm.

D．the waters of a pool are warmer

4.The passage is probably written for .

A．students at school B．kids who want to learn swimming

C．parents with little children D．coaches who teach kids to swim

5.In which column(栏目) of a magazine can you find this passage?

A．Education B．Science C．Entertainment D．Sports
