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 also break cover the 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.

    You may think there are no differences between British and American people. After all, they speak the same language, don't they? If you ask a British or an American person, he will probably tell you that there are differences. And the differences are quite great.

    What do British people think American people are like? The British think American people are very strange. They make a lot of noise and they laugh too loudly. They are rich, and they only think about money. But the British do say that American people are kind friendly people. They're happy to help you if you are in trouble.

    What do Americans think of the British? Well, they think the British are cold and very unfriendly. They are not interested in success or in making lots of money. They think British is the best country in the world. They look down on other countries. But Americans say that the British are quite hard workers. They are brave and honest. And in time of trouble they face difficulties happily.

    You can see that these ideas can cause misunderstanding between the British and Americans. But when American and British people become friends, they usually find things are not as bad as they expected.

    Nowadays more and more people like to travel, especially when vacations come. A great number of people rush out of their homes or companies to travelling spots. They either drive or take a bus, a train, a ship and so on. Some even ride bikes.

    However, there is another way of travelling—poorism. People have a tour in the poorest areas of the world. Some people may take one-day poorest tour, and some even pay to stay in very poor neighborhoods to experience the lowest living standards in the world. Poorism tours take place around the world, and not just in the third world countries. You can, for instance, tour New York neighborhoods in the Bronx, in the Bund of Shanghai. Such tours can take people into the heart of poor areas within large and in some rich cities. These tours may awaken people to pay more attention to long-standing poverty, or the effects of war.

    Some suggest that tours in the poor areas can raise social care. And the money from the tour can be donated to help the people there.

    What do Leonardo da Vincii, Marie Curie, and Albert Einstein have in common? They were all left-handed, along with other famous people including Brad Pitt Prince William, and Barack Obama. In fact, an estimated 13 percent of the world's population may be left-handed and still most people around the world are right-handed.

    What makes a person become right-handed rather than left-handed? As yet no one really knows for sure. One simple idea suggests that people normally get right-handedness from their parents. Studies have found that two right-handed parents have only a 9.5 percent chance of having a left-handed child, whereas two left-handed parents have a 26 percent chance of having a left-handed child. Another common theory is that left-handed people suffer mild brain damage during birth, which makes them left-handed. However, if this theory were true, it would not explain why the percentage of left-banded people is so similar in every society, when birth conditions vary so much from society to society.

    Whatever the reasons behind it, people's attitudes toward left-handedness have changed a lot over the years. Statistics show that although 13 percent of young people (10-20 years old) are left-handed, only 6 percent of the elderly are left-handed. Left-handed children used to be punished until they began using their right hand like other children, but today people who are left-handed are no longer looked down on nor are they considered abnormal. For most people today, either case is perfectly acceptable.

    Food is necessary for offering energy to our bodies, but sometimes we buy too much of it at the store. When your food starts to go bad, there are many other ways you can still make use of it instead of throwing it away.

    Before throwing away old bananas, you can use the peels (皮) to shine up metals and leathers. Press the peel against the surface, move it backwards and forwards and then polish clean it with an old cloth. Banana meat is also good for reducing wrinkles. Put a bit on those trouble spots, let it sit for a while, and then wash it off, and your wrinkles will go away. Lemons are great for lightening skin and hair. If you have trouble with some skin diseases, like red spots on your face, put a bit of fresh lemon juice on them and leave it overnight. You'll notice a difference in the morning. Apples will help ripen (使成熟) tomatoes quickly when they are placed together in a paper bag, and orange peels are great fire starters for your next backyard campfire party.

    If your dog or cat brings home fleas, using salt is a great way to get rid of them around the house. Just pour salt into the vacuum cleaner (真空吸尘器). Let it sit, then vacuum up the fleas. The salt can kill the fleas. Be sure to throw away the vacuum bag or empty the vacuum bin immediately, or some of the fleas can climb out.

    Beer is a great hair lightener. If you are out of lemons, try dipping your hair in beer before going outside. Just don't forget to wash it out afterwards. Milk is great for removing dirty marks, especially if it is some type of ink.

    As you can see, there are many other uses for everyday foods around the house. So next time, before throwing food away thinking it is of no use, stop for a moment and think about all their uses talked about here.

    Have you ever been to a music festival? Well if you live in the UK, the answer is probably yes. The number of festivals has grown greatly over the last few years and now there are around 200 every summer. So let's look at the history of four famous festivals.

    The Glastonbury Festival is a five-day festival of contemporary (当代的) performing arts held most years in Somerset, in the south-west of England. There are a rock and pop stage, a jazz stage, the Avalon stage, a theatre comedy stage, a cinema tent, a dance tent and a circus (马戏团). The festival started in1970and about 120, 000 people go to it every summer.

    The Reading Festival is truly world-class with rock and pop bands (乐队) appearing from all over the world, particularly (尤其) the USA. About 80, 000 music fans go to Reading every August Bank Holiday. The festival first came to its present site on the banks of the River Thames in Reading in 1971, when it moved from Plumpton in Sussex. It is still on the same site over 47 years later!

    WOMAD stands for World of Music, Arts and Dance and was the idea of rock musician Peter Gabriel to promote (宣传) world music. The WOMAD Festival started in 1982 and takes place in July at Charlton Park, near Malmesbury in Wiltshire, and you can see different bands and musicians from all over the world. The festival welcomes over 26, 000 visitors each year.

    The one-day Monsters of Rock Festival at the National Bowl in Milton Keynes was first held in 1980 and gave visitors the chance to hear the very best of hard rock and heavy metal. There were no festivals between 1996 and 2003 as a result of changing musical fashions, but now it has returned and grown into a two-day festival with a campsite for the 30, 000 people who go there in summer days.
