When people ask me to name typical British dishes, I have, however, struggled to think of an answer. Yes, we do have our own national dishes. We do have fish and chips, and we have other dishes like roast dinner and shepherd's pie. But how much do we actually eat them?

    Fish and chips, is made up of battered（绞碎的）fish and chips,which is often accompanied by a thick paste（酱）. The majority of British people really do love this dish but it is not something that we would eat,say,on a weekly basis.It's also not usually something that we would cook at home.The British people associate this dish with the seaside and it's something that will usually be eaten on a day trip there,bought from a takeaway fish and chip shop.

    Another favourite British dish is roast dinner.This is made up of roast meat,usually chicken or beef, accompanied by roast vegetables and a meat sauce called gravy（肉汁）.It is usually eaten on a Sunday,perhaps for a special family dinner.It can either be cooked at home or eaten in a traditional pub.We also eat a more elaborate version of this for our Christmas dinner.

    Although we do have our traditional dishes,our diet has been greatly influenced by other countries.You can find a wide range of international foods in the supermarket or varieties of different restaurants on our high streets.A famous saying amongst British people is that our national dish is now chicken tikka masala,a dish which is heavily influenced by Indian cuisine.

    Don't expect to be served a traditional dish if you ever get invited for dinner at a British family's home!

    A woman was sitting by herself in a movie theatre. The movie she was about to see was a musical version (版本)of a very successful book that had sold a million copies that year.

    As the woman was waiting for the movie to begin, she noticed that the theatre was very crowded but the two seats next to her were empty.

    Suddenly a large man carrying a big fur coat walked down the aisle (走廊) and sat down, placing the fur coat on the seat next to her.

    When the lights went out, the fur coat began to move, and the woman realized it was not a coat but a large furry dog. He was sitting up in the seat, watching the movie screen with great interest. As soon as the movie started, the dog began to nod his head and beat his paws（爪） in perfect time to the music.

    When the movie was over, the woman turned to the man and said, "Excuse me, sir, but I've never seen such a well-behaved dog in a movie theatre before. Does he go to the movies often?"

    "Oh, yes," replied the man.

    "And he seemed to enjoy everything so much," she said, "It was just amazing!"

    "As a matter of fact, it surprised me, too," said the man. "He hated the book!"

    Why YOUR keyless car could be gone in 23 seconds: It's a crime wave reaching high proportions and the gadgets(小装置) used to hack into your car and steal it are being sold to thieves by High Street locksmiths.

    Car thieves are using high-tech gadgets to break into and steal cars in seconds. One thief stands by a house to pick up a signal from a car key using a relay. The relay broadcasts the signal to the car, where a second thief opens the door. The scheme, which does not involve breaking windows, steals cars in seconds.

    Thousands of cars across Britain are at risk of a new form of high-tech theft which allows thieves to fool bypass the security systems in keyless cars using a relay system to boost the signal. So-called 'relay' theft occurs when two thieves work together to break into keyless cars. They use equipment to capture electro-magnetic signals emitted by key fobs. Any vehicle with keyless entry could be easily stolen. These include cars from BMW, Ford, Audi, Land Rover, Volkswagen and Mercedes.

    A unique experience awaits you at the Centre for Alternative Technology on the edge of the beautiful Snowdonia National Park.

    Over thirty years ago a group of people decided to try out alternative technologies. They chose a remote empty place, where rock used to be dug from the ground, as their base. Here experiments offering solutions to the world's energy problems were carried out, and nowadays many of these ideas have become common practice. You can experience all these for yourself in just one day with us, and then take away what you have learned and put it into practice at home. Be assured it will help you save on your household energy costs!

    Your visit to us begins with a ride up a steep 60-metre hillside on a railway which is worked by using the weight of water. At the top of the mountain you will enjoy beautiful views to the distant coastline. Then interactive displays show the power of wind, water and sun, while showing you what can be done in an ordinary household to reduce your influence on the planet.

    There was no soil when the project was started, so we created our organic gardens using our own home-made soil. You can enjoy woodland walks or even notice spring flowers growing on the roofs of environmentally-friendly buildings.

    In 2006 we opened our new eco-adventure playground for children, and we also run workshops where they can make models and become inventors of the future by putting wind, water or solar power into their own designs.

    The Centre for Alternative Technology is open all year round and has good rail, road and cycle links. In fact we offer a 50% reduction on the admission price if you arrive by bicycle. There is wheelchair access for disabled visitors—telephone us in advance if you would like assistance.

    When we see a person in trouble, the first idea that comes to our mind is to lend a hand. But what if we see an animal in trouble, does the same rule apply?

    This question was raised after a group of penguins were saved from an icy gully（峡谷）in Antarctica. It was filmed for the BBC wildlife series Dynasties. The film crew were anxious when they saw that a group of penguins had fallen into a gully and been trapped with their young. They built a slope（斜坡）so that a few of the penguins could save themselves.

    The case has taken the international media by storm. Viewers watching this film let out a sigh of relief. "I'm so glad. I understand not taking action directly, but a helping hand isn't bothering, right?" viewer Kathryn Shaw said on her Facebook.

    However, others think human interference（干涉） is unnatural. "You can't have sunshine throughout your life. To have done anything else would only make matters worse," said the show's creator David Attenborough, according to The Times.

    In this case, however, Mike Gunton, the executive producer of the series, said that this was a one­off situation. "There were no animals going to suffer by interfering. You weren't touching the animals and it was just felt by doing this... they had the chance not to have to keep slipping down the slope," he told the BBC.

    Such cases are familiar to Paul Nicklen, wildlife photographer for National Geographic. He told Metro, "If it's ever a predator（捕食者）situation, no matter how gut­wrenching, you stay out of the way. Even when you're watching a male polar bear eat a baby bear."

    "There's no rule book in those situations. You can only respond to the facts that are right there in front of you," Will Lawson, the show's director, told Daily Mail.

    Have you ever spent an afternoon in the backyard, maybe grilling or enjoying a basketball game, when suddenly you notice that everything goes quiet? There is an old phrase "calm before the storm", often used in a situation—a quiet period just before a great activity or excitement. According to our own experience, we know there is actually calm before the storm. But what causes this calm? And is it always calm before the storm? Let's hear what scientists have to say.

    A period of calm happens in a particular kind of storm, the simplest kind of storm—a single-cell thunderstorm. In this type of thunderstorm, there is usually only one main updraft, which is warm, damp air and drawn from places near the ground. Storms need warm and damp air as fuel, so they typically draw that air in from surrounding environment. Storms can draw in the air that fit their need from all directions—even from the direction in which the storm is traveling.

    As the warm, damp air is pulled into a storm system, it leaves a low-pressure vacuum (真空) coming after. The rising air meets the cold dry air that has already existed in the storm clouds, thus the temperature of the warm, damp air drops, and the water vapour (水蒸汽) in it changes into tiny drops that are a precondition of rain. These drops accumulate and build on larger particles like dust, until they grow large enough to form raindrops.

    This warm, damp air keeps moving upwards, but it becomes cooler and drier during its trip through cloud. When it reaches the top of the cloud, the air gets spit out (被挤出) at the top. This air is sent rolling out over the big thunderclouds. From there, the air goes down. Warm and dry air is relatively stable, and once it covers a region, that air, in turn, causes the calm before a storm.

    Most thunderstorms, though, don't start with calm. That's because most are actually groups of storms with complex wind patterns. There's so much air moving up and down storm groups that the calm before the storm never happens. Instead, before the storm,让 might be really windy!
