    There are many dangerous sea creatures in the world. The following are some examples.

    The needlefish are commonly seen living near the surface of tropical (热带的) waters. But they can alsobreak coverthe water，and once in the air they can become dangerous flying swords. Though it is rare，people have been seriously hurt and even killed by the fish．Night fishermen in small boats are at particular risk because their lights may attract the fish.

    Saltwater crocodiles are the world's largest crocodiles，sometimes reaching 23 feet in length and topping 2，200 pounds. Yet these crocodiles hunt quietly，lying in wait below shoreline waters to attack turtles and thirsty animals that have come to drink. Saltwater crocodiles kill a number of people each year.

    There is no doubt that the great white shark sits atop the ocean food chain. The world's largest fish can weigh at over 5，000 pounds and reach lengths of more than 20 feet. Great white sharks have about 3，000 teeth，which they typically sink into sea lions，seals，and sea turtles. These sharks are responsible for a third to a half of the 100 shark attacks on humans every year.

    The sea anemone (海葵) may look like the beautiful flower for which it's named，but fish that swim too close may regret it. The sea anemone，which lives on the sea floor，uses its poisonous tentacles (触须) to stab passing creatures with a kind of poison—making them helpless and fit to be eaten.

    The surgeonfish (刺尾鱼) is an attractive reef fish that is poisonous. Scientists believe that the world's seas hold some 1, 200 different surgeonfish species and think that they injure about

    50，000 people per year. But the surgeonfish poison can also bring great benefit—they are useful in the development of new drugs.

    At first, muffled (听不太清的)conversations made researchers at a San Diego aquarium puzzled, but when a diver thought he was being told to get “out” of the water they realized the conversations were coming from a white whale.

    Noc was about one year old when he was caught off the Pacific coast of Canada. He was kept in an open-ocean pen (围栏) at the US National Marine Mammal Foundation in San Diego, California. After seven years at the Foundation, he began, automatically, to make unusual sounds, a report in the latest issue of the journal, Current Biology, said.

    “We thought of the whale' s vocalizations(发出的声音) as an attempt to imitate humans. Whale vocalizations often sounded as if two people were talking just out of the range of our understanding,” the authors said. “ 'These conversations' were heard several times before we finally realized the whale was the source.” The researchers realized it was Noc when a diver surfaced and asked, “Who told me to get out?” It was then that they realized the word “out”, which was repeated several times, had come from Noc. Later, his speech-like sounds were recorded in the air and underwater.

    Noc started making the sounds after seven years in the open-ocean pen, and continued making them for another four years. He died five years ago. Researchers have now analyzed the sound recordings. It was the first time that sound recordings had shown how such sounds imitated speech and were different from the usual calls of the species.

    The speech-like sounds were lower than normal whale sounds and much closer to those of the human voice. Also, whales talk to each other by blowing air through their noses, rather than using a larynx(喉), as people do.

    “We don't claim that our whale was a good imitator compared to such well-known imitators as parrots,” the researchers said. “However, the behavior we observed is an example of vocal learning by the white whale. It seems that Noc's close association with humans played a role in how often and how well he employed his human voice.”

    Every year I spent my holidays in the countryside in my grandparents cottage. I really like spending time there. What I love mostly about rural areas is the peace or silence. This year I'm going to ride my bike, and swim in the amazed lake and the swimming pool. I'll also meet best friend Sara. But I will have some duties too, because of my grandparents often need the hand with housework and gardening. I'm really looking forward to go there. I will finally be able to relax myself after the school year, that seems a long time. I'm sure I'll have a good time.
