     The view over a valley of a tiny village with thatched(草盖的)roof cottages around a church; a drive

through a narrow village street lined with thatched cottages painted pink or white; the sight over the

rolling hills of a pretty collection of thatched farm buildings __these are still common sights in parts of

England. Most people will agree that the thatched roof is an essential part of the attraction of the English

countryside.

     Thatching is in fact the oldest of all the building crafts practiced in the British Isles. Although thatch

has always been used for cottage and farm buildings, it was once used for castles and churches, too.

     Thatching is a solitary(独自的)craft, which often runs in families. The craft of thatching as it is

practiced has today changed very little since the Middle Ages. Over 800 full-time thatchers are

employed in England and Wales today, maintaining and renewing the old roofs as well as thatching

newer houses. Many property owners choose thatch not only for its beauty but because they know

it will keep them cool in summer and warm in winter.

     In fact, if we look at developing countries, over half the world lives under thatch, but they all do

it in different ways. People in developing countries are often unwilling to go back to traditional materials

and would prefer modern buildings. However, they may lack the money to allow them to import the

necessary materials. Their temporary mud huts with thatched roofs of wild grasses often only last six

months. Thatch which has been done the British way lasts from twenty to sixty years, and is an effective

defence against the heat.
