The Heritage(遺產(chǎn)) at Risk programme aims to understand the overall state of England’s heritage by assessing each of its different elements. In particular we need to indetify those that are facing the greatest pressures and threats. We will use thes information to work out how to reduce those pressures and in turn to calculate the resources needed to make our unique heritage of historic places safe.

You can search for sites on the register by entering a site name,location,street or educational block in the box below.

Conservation areas

   A nationwide survey of conservation areas indicates that approximately 1 in 7 is at risk  from neglect(疏忽),decay(腐爛)or unpitying change.

   Show your suport for our campaign go save conservation areas from unavoidable declineand receive a free campaign pack by registering. There are some 9,300 conservation areas across England, meaning that we all live in or near to one or visit one regularly for work, shopping or rest. They are the element of England’s heritage that is all around us and which touches all of our lives. But until now no one had a clear idea what condition they were in.

Buildings

The task of assessing condition and risk started with buildings. Following a survey of all grades of listed buildings in London, English Heritage published in 1991 the first annual register of those at risk there.

The success of this London work led to the national buildings at risk strategy in 1998, and publication of a register of buildings at risk covering all grade I and II listed buildings and structural scheduled monuments in the country, at risk and vulnerable(易受傷害的).

Parks&Gardens

There are 1,600 entries on the current English heritage Register of Historic Parks and Gardens of Special Historic Interest. Sites at risk have typically been adversely(不利地) affected by development and neglect; often they have been changed by development and are faced with major change. Sometimes development beyond the boundary of a registered landscape can be just as harmful as construction within its boundaries; this is especially true that development would influence designed viwes that extend beyond the chosen site itself.

1.the purpose of using the information to work out how to reduce pressures is to      .

A.assess each of English heritage’s different elements

B.identify those that are facing the greatest pressures and threats

C.calculate the resources needed to make heritage of historic sites safe

D.help you to search for sites at risk on the register

2.It can be inferred  from “Conservation areas” that conservationareas across Elngland      .

A.are almost all at risk from neglect, decay or unpityuing change

B.can be entered with a campaign pack free of charge

C.are in very close connection with our lives

D.are in whatever condition people are sure about

3.The text mainly talks about      .

A.English heritage at risk    B.historic places of interest

C.English heritage register   D.location of English heritage

4.According to the last paragraph, the bad effect development has on the sites at risk is that      .

A.it has changed the sites at risk with no intention

B.it can sometimes cause harm beyond the registered boundaies

C.it would affect  the designed views instead of the chosen sites

D.it has neglected the local people of special historic interest
