As we know, we all need a healthy environment. I wonder  1  we can work to reduce carbon dioxide(二氧化碳)around us. Well, here 2  some ways to follow.

    ▲Only turn the water heater  3 when necessary, and the temperature controls to avoid overheating. Put a lid on a pan when boiling water.

    ▲When using the washing machine, be sure there's a full load and turn the temperature down  4  it's not really dirty.

    ▲Save energy by using efficient(节能的) light bulbs. They use about 5  the energy of normal bulbs and last 10 times as long.

    ▲Each week, choose one day when you don't eat meat. Meat uses up lots of energy because it  6 a long time to produce.

    ▲Food production eats up lots of energy. When you buy food, go local rather than imported(进口的), and get fresh vegetables  7 frozen(冷冻的).

    ▲Take showers rather than baths and reduce your shower time by two minutes. This  8 water and give you an extra two minutes in bed.

    ▲ Look for something reusable and recyclable, and remember  9  your reusable shopping bags!

We can do more things to recycle  10 we can reduce carbon dioxide in the air and we all have a strong and healthy body.

     Some inventions are very important. For example, the telephone allows people to communicate all over the world. The 1 lets people travel long distances in a short time. Life is much easier with these 2inventions.

     Some inventions are just fun. A company in Japan has invented3 flowers. You can listen to music that comes through real flowers. Customers in restaurants can smell the beautiful roses 4listen to pleasant music while eating. People in the dentist's office can look at pretty lilies and listen to Mozart while having their 5examined!

     There is now a vehicle that gets you around with almost no effort 6. In fact, you drive this invention while standing on it ! This vehicle runs by electricity. It 7 quite easily. When you lean forward, it moves forward, and when you lean 8, it moves backward!

     A new kind of bubble(气泡) liquid（液）has been invented. If you blow bubbles 9 this liquid, they can last for several minutes! 10 are very strong. You can even pick them up and throw them around!

     Do you have your own ideas about inventions now?

    There are many kinds of pollution around us,1 air pollution, soil pollution, noise pollution and light pollution. They are bad 2our health in many ways.

    Burning gas, oil and coal creates air pollution. It can cause sore eyes and 3 problems.

    With the increase of pollution and the 4 of industry, litter is everywhere. It makes our environment dirty. People put lots of rubbish in the land. Farmers use too many chemicals in the fields. They destroy the soil. So soil pollution has become serious.

    Noise pollution can make people 5 For example, people may lose their hearing if they work in a 6 place for a long time. Too much noise can cause high blood pressure 7

    Working for a long time in strong, changeable light 8 cause some kind of illnesses. It makes people feel 9 and is especially bad for the eyes.

With 10 pollution, our planet will become greener and our health will be better. Let's be greener people.

    Christmas is coming.1 you are thinking what gifts you need to buy, the Alice Ferguson Foundation is busy 2 the environment by building relationships between people and nature.

    At the 3 of the year, it designs events to help children celebrate Christmas without increasing the amount of 4 they create.

    Hanna Seligmann who works for the foundation, said they 5 that from Thanksgiving Day to New Year's day, the household trash increases by 25 percent. Many young people do not know the6 they throw away do not decompose (分解), or break down, at the same rate. For example, paper dissolves（溶解） in about four weeks. A metal can take up to 100 years. A plastic bag will not decompose for 450 years. Glass takes 1,000 years.

    Hanna Seligmann shows adults and children 7to reduce waste during the holiday gift-giving season.

    She encourages using things that are 8 in our houses like newspaper or old magazines. With imagination，children can wrap gifts in a 9 napkin or even a beautiful scarf. In fact，there's no better way to celebrate the holiday by giving10to the planet.

    As we know, life today has many problems. One of the biggest is 1, such as water pollution, air pollution, 2 pollution and so on. Water pollution makes our rivers and lakes 3. It kills fish and pollutes our drinking water. Air pollution is the most serious kind of pollution. 4 bad for living things in the world. Noise pollution 5 us talk louder and become angry 6.

    The Earth is 7 home and we must save it. We can't 8 rubbish here and there. We should go to work and school 9 bus or with our friends in the same car. Everybody 10 save the Earth.
