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(工艺)practised 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 practised toady has changed very little since the Middle Ages. Over 800 full-time thatchers are employed in England and Wales today, keeping 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 get 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 defiance against the heat.

小题1:Which of the following remains a special feature of the English countryside?

A.Narrow streets lined with pink or white houses.

B.Rolling hills with pretty farm buildings.

C.Cottages with thatched roofs.

D.Churches with cottages around them.小题2:What do we know about thatching as a craft?

A.It is a collective activity.

B.It is practised on farms all over England.

C.It is quite different from what it used to be.

D.It is in most cases handed down among family members.小题3:Thatched houses are still preferred because of _________.

A.their style and comfort

B.their durability

C.their easy maintenance

D.their cheap and ready-made materials小题4:People in developing 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

什么是“和谐社会”?社会学认为,社会是由人群组成的一种特殊形态的群体形式,是相当数量的人按照一定的规范发生相互联系的生活共同体,它的特征之一是具有结构性。而社会结构是指社会系统的各组成部分或社会体系中诸要素之间比较持久、稳定的相互联系模式。只有社会的经济、政治、文化、生活的各个领域和部分都紧密联系、互相协调,整个社会才能始终保持有序和谐的状态。所以,“和谐社会”就是说社会系统中的各个部分、各种要素处于一种相互协调的状态。“和谐社会”实际上是一种整体性思考问题的观点,要求我们在把工作视野拓展到政治、经济、社会、文化等各个方面,运用政策、法律、经济、行政等多种手段,统筹各种社会资源,综合解决社会协调发展问题。著名的政治学家亨庭顿关于现代化引起不稳定,现代化伴随着风险的观点已经得到了许多国家经济社会发展经验的验证。即现代化起飞的时期(从农业社会向工业社会过渡时期),是进入社会结构错动、社会问题增多、社会秩序失范、社会风险易发的时期。我国社会转型正面临关键的临界点,即进入了社会发展的矛盾凸显时期,也就是社会失调时期。这种由社会结构内部不协调而产生的矛盾、冲突或人们的无序互动导致的紧张状态而产生的压力.称为社会张力。当社会张力的能量逐步积蓄起来,会对社会结构形成巨大的冲击力,并在社会结构最薄弱的环节释放出来。而这种无序的社会力量的爆发就是社会危机或叫社会风险。

这十几年是我国社会经济发展最快的时期,也是人民群众得实惠最多的时期,但并不是各方面完全协调发展的时期。我们的主要精力一度集中在经济建设上,而忽略了各种社会问题。有的人在GDP崇拜下,只讲效率而忽视了公平,使社会问题有积压、增多的趋势,甚至以牺牲一个阶层(群体)的利益去满足另一个阶层(群体)的利益,形成了诸多社会不稳定因素,使社会运行不顺畅。正是在这种社会背景下,提出了“和谐社会”的问题。

要建设和谐社会,自然地涉及作为执政党解决这些社会问题的能力。提高我们党的执政能力,就必须提高我们党整合社会结构、社会利益、社会关系等能力。因此,作为社会主义国家的执政党,必须按照构建社会主义和谐社会的目标,从社会整体利益和人民长远利益出发,正确引导和处理各种社会矛盾,尽可能将社会转型的代价降低到最低程度,使整个社会结构协调与和谐,顺利渡过社会发展的阵痛期。
