Turns out，you're not just what you eat—you're also where you eat．

  Researchers found out that people had double the number of calories(卡路里)when standing in a messy kitchen compared to when they stood in an orderly one．

    The researchers had 98 women spend to minutes in kitchens，under the guise of (以……为幌子)asking them to wait for someone．Half of the women stood in a messy kitchen，with piles of newspapers，dirty dishes and a ringing phone．The other half of the women waited in a clean kitchen．

    Both kitchens had bowls of biscuits and carrots．Each woman in the messy kitchen ate twice as many cookies compared to those in the clean kitchen．

    Why did this happen?

    “Being in a messy environment and feeling out of control is bad for diets，''Lenny Vartanian，one of the researchers，said．“It seems to lead people to think，‘Everything else is out of control,so why shouldn't I be?'''

    The study's size was small，but the findings prove something we know all too well：Stress(压力)is bad for you．Stress often causes people to overeat．Beyond weight gain，too much stress can also increase a person's heart rate，and lead to painful conditions like headaches．

    While there are many ways to manage stress．including listening to music and exercising，this study shows that there are easy and quick things you can do to find calm．The next time you don't want to tidy up the kitchen，remember that the exercise will help you a lot in so many ways．

    It is park at the bottom of the ocean. It's cold down there too. There's no air to breathe. The water pressure is high. There may be fishes that could hurt you. The deep sea can be an unpleasant place. But people are still fascinated by it, not just because of the amazing scenery. The seafloor might hold the secret to the beginning of life on Earth.

    Oceans cover more than two-thirds of our planet. Yet, we have explored just a small part of the underwater world. A new project is there to explore the ocean deeper. A new US machine can carry people down to as deep as 6,500 metres. It will take the place of an older machine called Alvin. The old one has been in use for 40 years, but it can only go down to 4,500 metres. Alvin played a key role in many important tasks. Alvin helped biologists collect worms, chemists gather rocks, and oceanographers (海洋学家) map the seafloor and take water sample (样本).

    But now it's about time for a new one. The new machine will be like Alvin. It'll also be about 27 feet long, about the size of a small school bus. The seating area inside will be small, about two metres wide. Like Alvin, it'll carry a pilot and two passengers. It will be able to move like Alvin does. It'll give passengers more chances to enjoy the view. Alvin has only three windows. The new one will have five. It will travel more than a mile an hour faster than Alvin. Getting to the bottom faster and moving around more quickly will allow researchers to make the most of their time underwater.

    Around the world, there are about 7,000 National Parks. Most of them cover huge areas of land where nobody lives. However, the National Parks in England include places where people live and work, as well as wild areas where there are few human activities.

    The National Parks in England are called "England's Breathing Spaces" because they are places where people can go to be in the open air, away from the dirt and noise of cities. They provide wonderful scenes of mountains, woods, grasslands and wetlands. And there are plenty of activities to do in all of the National Parks in England. Visitors can walk or ride bikes for fun. Many of the parks put on activities for families.

    Every year there are about 110 million visitors to the parks, bringing many benefits(益处) to the areas. At the same time, it creates problems, too.

    First, life can be difficult for local people. Car parks and roads are too crowded. Gift shops and cafes take the place of many everyday shops. Even house prices in some areas can become too high. Besides, country roads can be damaged, for too many people walk, cycle or ride horses on them. Roads can be rebuilt, but then they look less natural. Another big problem to the National Parks is litter. In the parks it is a danger to wild animals. Broken glass can also cause fires by focusing the rays of the sun. Such fires in wild places can be out of control.

    _______All National Parks in England are making more rules, which tell people how to take good care of their environment. If these rules are followed, the National Parks will be well kept and continue to give pleasure to many people for a very long time.

    Bamboo(竹子) is one of nature s most surprising plants. Many people call this plant a tree, but it is a kind of grass.

    Like other kinds of grass, a bamboo plant may be cut very low to the ground, but it will grow back very quickly. A Japanese scientist reported one bamboo plant which grew 1.5 metres in 24 hours! There are more than 1, 000 kinds of bamboo. Bamboo grows almost everywhere in the world, but in Europe, they can't grow.

    Not all bamboo looks the same. Some bamboo plants are very thin. They may only grow to be a few centimetres wide while others may grow to be more than 30 centimetres across. This plant also comes in different colours, from yellow to black to green.

    Bamboo has been used to make many things such as hats and kitchen tools. Because it is strong, bamboo is also used to build buildings.

    Many Asian countries have used bamboo for hundreds of years. They often use bamboo for buildings and supporting(支撑) new buildings and bridges while they are being built.

    In Africa, poor farmers are taught how to bring water using bamboo. These African countries need cheap ways to bring water because they have no money, and their crops often die from no rain and no water. Bamboo pipes(管子) help poor farmers bring water to their thirsty fields without spending much money.
