科目： 來(lái)源： 題型：

Do you know that you can help the environment if you buy recyclable products instead of non-recyclable ones? Look for the recycle symbol-three arrows (箭頭) that makes a circle-on the package (包裝) .People reuse things to make recycled products. It usually takes less energy to make recycled products than to make new ones. The more energy we save,the better.

Imagine that it's a hot summer day. You put an ice cream on the sidewalk,and it melts (融化) .Why does this happen? Well,you may know that the sun causes the ice cream to melt. But you may not know that we get solar energy from the sun. Solar energy is another way of saying “energy that comes from the sun. ” Solar energy can be used to heat homes,buildings，water,and to make electricity (電) .

Cars are an important part of life for most people. But cars also cause pollution and give out a lot of greenhouse gases into the air. It's lucky for us to have some cars that are better for the environment now. These cars can travel longer with less gasoline (汽油) . They don't pollute much,either. There will be less greenhouse gases if we use these kinds of cars.

Many things,like computers, TVs,and VCRs,have special labels (標(biāo)簽) on them. You can find the word “Energy” on the label and it also has a picture of a star. Products that have ENERGY STAR labels are made to save energy. Buying such products will help protect the environment.
