Stone is all around us. Stone is usually very hard,       it can also be soft. Stones have many uses. 

In some      , artists carve (雕刻) beautiful things out of soft stones, because they can be shaped easily. In ancient times, people carved       persons or animals out of soft stones, which could be carried along with. While in some European countries, statues (雕塑) are carved         hard stones and they do not change easily. In summer, the hot sun      on these statues and in winter the snow falls on them, but they       remain beautiful.

Some stones are coloured, so they make the       look wonderful. People can also get a fire with stones. Besides, some kinds of stones can be used to       jewellery (珠宝). We’ve found stones are really amazing.
