（A）
The view over a valley of a tiny village with thatched（茅草盖的）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 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（行业）practiced in the British Isles. Although thatch has always been used for cottages 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 today has 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 modem buildings. However, they may lack the money to allow them to import the necessary materials. Their temporary（临时的）small mud house with thatched roofs of wild grasses often only last six months. Thatch which has been done in the British way lasts from twenty to sixty years, and is an effective defense against the heat.
1. Which of the following remains a unique feature of the English countryside ?
A. Narrow streets lined with pink or white farm buildings.
B. Rolling hills with pretty farm buildings.
C. Cottage with thatched roofs.
D. Churches with cottages around them.
2. What do we know about thatching as a craft?
A. It is a collective activity.
B. It is in most cases handed down among family members.
C. It is quite different from what it used to be.
D. It is practiced on farms all over England.
3. People in developed countries also live under thatch because
A. thatched cottages are a big tourist attraction
B. thatched roof houses are the cheapest
C. thatch is an effective defense against the heat.
D. they like thatched houses better than other buildings
4. Thatched houses are still preferred because of
A. their style and comfort
B. their high quality
C. their easy keeping
D. their ready-made materials
（B）
Coketown was a town of red brick, or of brick that would have been red if the smoke and ashes had allowed it; but in fact it was a town of unnatural red and black like the painted face of savage（野人）. It was a town of machinery and tall chimney, out of which smoke trailed themselves for ever and ever. It had a black canal in it, and a river that ran purple with ill smelling color, and large piles of building full of windows where there was a rattling and a trembling all day long, and where the steam-engine worked up and down like the head of an elephant in a state of madness. The town contained several large streets all very like one another, and many small streets still more like one another, inhabited（居住）by people equally like one another.
A sunny midsummer day. There was such a thing sometimes even in Coketown. Seen from a distance in such a weather, Coketown lay covered in a smoke of its own. You only knew the town was there, because you knew there could have been no such a place upon the view without a town.
The streets were hot and dusty on the summer day, and the sun was so bright that it even shone through the smoke over Coketown, and could not be looked at steadily. Workers appeared from low underground doorways into factory yards, and sat on steps, wiping their face sand looking at coals. The whole town seemed to be frying in oil. There was a smell of hot oil everywhere. The atmosphere of those places was like the breath of hell（地狱）, and their inhabitants wasting with heat, walked lazily in the desert. But no temperature made the mad elephants more mad or more sane（理智的）. Their tiresome heads went up and down at the sane rate, in hot weather and in cold, wet weather and dry. The measured movement of their shadows of wood; while for the summer noise of insects, it could offer all the year round, from the dawn of Monday to the night of Saturday.
