Cut the Carbon Footprint

Everything you do leaves a “ carbon footprint”(碳足迹). For example, When you travel in a taxi, the car gives off (排放) CO₂ into the air. CO₂ is a greenhouse gas. Greenhouse gases make the earth become warm. To protect our environment, we need to leave less of a “carbon footprint”. How big is your carbon footprint? To get an idea, take a look at the following numbers.

Living areas

l  TV sets and DVD players produce 723kg of CO₂ a year.

l  If you turn them off when you’re not using them, you can cut that number by 108kg.

Laundry room (洗衣房)

   Drying clothes in a dryer produces a lot of CO₂

l  If you use your dryer five times per week, you produce 185kg of CO₂ per year.

l  Dry your clothes in the sun instead.

Bathroom

l  If you take an eight-minute shower every day, you produce 616kg of CO₂ a year.

l  If you only use six minutes to take a shower, you can cut that number by 154kg a year.

根据短文内容，判断下列句子的正误，正确的用“T”，错误的用“F”。 1 CO₂ is a greenhouse gas that can make the earth warm.

2 Watching TV and traveling in a taxi can produce little CO₂.

3 If we use a dryer five times per week, we produce 154kg of CO₂ per year.

4  If we spend less time taking a shower, we can cut the number of CO₂.

5 The less of a “ carbon footprint” we leave, the better our environment will become.

The world is becoming smaller by using modern traffic, TV, telephone and so on. Life today is easier than it was hundreds of years ago, but it has also brought new problems. One of the biggest is pollution. Pollution comes in many ways. We see it, smell it, drink it and even hear it.

The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. Man is now slowly polluting the whole world.

Air pollution is still the most serious. It’s bad to all living things in the world. Water pollution kills our fish and pollutes our drinking water, noise pollution makes us become angry more easily. The pollution of SO₂ is now the most dangerous problem of air pollution. It is caused by heavy traffic. It is true that if there are fewer people driving, there will be less air pollution.

Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city. So the less pollution there is, the better life people will have.

A long walk in the desert or the mountains can be exciting. And it’s a great way to keep fit. If you carry a tent and some food, you can camp overnight. But wild places can be dangerous. Here’s how you can enjoy walking and camping safely.

Before your trip

☆ Tell someone where you are going and when you expect to return. If you don’t return on time, the people at home will know that you are lost or in trouble. They will know where to look for you.

☆ Make sure you’ve got a good map of the area that you’re going to.

☆ Make sure you’ve packed the right equipment for your activities. The desert is often hot, but nights can be very cold, and sometimes there are big rainstorms. In the mountains, the weather can change suddenly. A sunny day can turn cold and cloudy quickly.

The tools for survival(生存)

Sunglasses, sun hat, sun cream, windproof jacket, good walking shoes or boots, food, water, maps, compass, first-aid kit, matches, rope, knife, ground sheet,

the pack to carry your equipment.

What to do if you get lost

☆ If you’re in a car and it has broken down, stay with your car.

☆ If you are not traveling by car, make yourself easy to see. A signal fire can be seen at night. During the day, smoke may be used to show where you are. A brightly-colored blanket(毯子) may help rescuers to find you.

☆ Stay where you are.

☆ If you walk for any reason, avoid walking during the hottest part of the day. Morning and evening walking is better for saving your energy water.

☆ Keep yourself away from the rain, wind and sun, but remember: try to make yourself be in sight.
