雅思小作文范文如下：

The bar chart shows the amount of different elements required for making 1,000 polystyrene and paper cups.

These two kinds of elements are heated with great quantities of steam which is ten times as much as other chemicals. This process is rather energy-saving, only costing 0.6 m3 of water and 6 kilowatts of electricity.
