Energy is everywhere. We use energy every day.

    Electricity is a form of energy and this is what powers the TV, hairdryer, phone, fridge, electric toothbrush and more! Our growing need for energy is one of the problems facing the world today, because producing electricity also produces pollution.

    Here are some simple ways to make a big difference when using electricity.

On or off? Leaving televisions and computers on with the little red light showing still uses electricity, even though they might look like they're turned off. To stop this you can turn them off.

    Lights out! Turning lights off when you're not in the room can save a lot of energy.

    Fridge door closed. The fridge is an important part of the kitchen, because it keeps food fresh, cool and healthy! But it takes a lot of energy to keep cool, so try not to leave the fridge door open or put hot things inside.

    Use the sun's energy. An increasing number of people are fitting solar panels（太阳能电池板） to their houses. They create electricity from sun-light, which can then be used to power our homes. Solar heating panels make hot water, reducing the need for electricity or gas.

    Which is the tallest mountain on the earth? The answer must come fast—MT Everest, at a height of 29,000 feet.

    But that is only on land. For, if you were to measure (测量) from the bottom (底部) of the ocean. The tallest mountain in the world will probably be Mauna Kea in Hawaii. It is more than 15,748 feet under the sea and another 13.779 feet above it.

    As US scientist Cindy Lee Dover points out that the seafloor is the largest and least known place on the earth. We know more about Mars (火星) and Venus (金星) and the back side of the moon than we know about the seafloor.

    Some people have travelled to the deep water of the ocean to try to find all kinds of unknown animals and plants living in the deep water. Even scientists know very little about them. Many of them perhaps do not even have names. Some of the names given by scientists to newly discovered (被发现) animals are really funny. Among them are the spaghetti worms (意大利面蠕虫), named as such it is found in a tangle (缠结), it is often difficult to make out where one ends and another begins! Just like spaghetti.

Twenty percent of all the water that goes into oceans around the world comes from one river — the Amazon.

The Amazon River{#blank#}1{#/blank#}from the Andes Mountains in Peru.It travels about 6，400 kilometres to the Atlantic Ocean.It is the largest river in the world.It is{#blank#}2{#/blank#}the second longest.Most of the Amazon's water comes from rain.During the rainy season, parts of the{#blank#}3{#/blank#}are 190 kilometres wide.

When people take a vacation, many choose to visit places of interest. But can they always enjoy it? The fact is only some of them can get pleasure sometimes. What makes one trip more enjoyable than another? The most important is to plan well. 

First, choose a right season to travel, Many places of interests have special beauty and activities in different seasons. Summer is the best season to swim in the sea. If you enjoy making a snowman, you should go travelling in winter. 

Second. you must find right vehicles. Travelling by plane is quick but expensive. But you will have to miss the beauty along the way. If you have enough time and want to enjoy the beauty out of the window, you can take the train. 

Third, traveling always makes you tired. So finding a nice hotel to have a good rest is necessary. We'd better make sure what kind of room we need. How are the conditions of the room? What's the price of the room?

Every minute that you spend in planning your trip may save your ten minutes of trouble during your trip. It may also add an hour of pleasure!
