答案解析：C段一整段都在探讨人们对哈拉帕文明衰落原因的推测，27题的题干只是将这些具体的内容总结了一下，因此确定C为争取答案。

第28题选：H

对应原文：H段：By investigating responses to environmental pressures and threats,we can learn from the past to engage with the public,and the relevant governmental and administrative bodies

答案解析：H段从2句开始，都在描述考古学对我们今天处理气候变化的意义。对应题干中a present-day application of some archaeological research findings，由此锁定答案。

第29题选：A

对应原文：A段：But their lack of self-imagery–at a time when the Egyptians were carving and painting representations of themselves all over their temples–is only part of the mystery.

答案解析：A段最后提到哈拉帕文明与埃及文明的不同。哈拉帕文明没有留下太多关于自身的记载，而埃及人则在庙宇各处留下自己的雕像和绘画。对应题干a difference between the Harappan Civilisation and another culture，由此确定A为答案。

第30题选：B

对应原文：B段：As populations increased,cities were built that had great baths

答案解析：B段中部提到了哈拉帕文明繁盛时期的城市设计。各种设施按照区域分布，房屋按照街区规划，还有自己的水井和排水系统。对应题干urban design，由此锁定答案。

第31题选：D

对应原文：D段：…found early in their investigations that many of the archaeological sites were not where they were supposed to be

答案解析：D段开头提到，两位学者在他们的研究早期发现，许多考古地址并不位于他们应该在的地方。后面还提到这些聚居点跟之前已经发布的内容存在几百米到上千米的误差。对应题干discovery of errors，由此确定答案。

第32题是：shells

对应原文：E段：…north-western India,where hundreds of Harappan sites are known to have been situated.The researchers gathered shells of Melanoides tuberculata snails

答案解析：根据north-western India定位到E段的这两句话，空前词collecting与gathered同义替换，根据修饰关系确定shells为答案。

第33题是：lake

对应原文：E段：As today,the major source of water into the lake is likely to have been the summer monsoon

答案解析：顺着上一题往下，根据water定位到E段的这句话。题干中问的是什么里的水位，原文中只有lake填上去语义合适，由此确定答案。

第34题是：rainfall

对应原文：E段：when the amount of evaporation from the lake exceeded the rainfall–indicative of a drought.

答案解析：根据evaporation定位到这句话，题干中less…than与exceed反义替换，由此确定答案为rainfall。

第35题是：grains

对应原文：G段：Petrie and Singh’s team…They are analysing grains cultivated at the time,and trying to work out whether they were grown under extreme conditions of water stress,and whether they were adjusting the combinations of crops they were growing for different weather systems.

答案解析：根据Petrie and Singh’s team定位到G段。空前词look at与analysing同义替换，由此确定答案为grains。

第36题是：pottery

对应原文：G段：They are also looking at whether the types of pottery used

答案解析：顺着上一题往下，根据also定位到这句话。从题干可以推测空上填的应该是某种具体的物品，原文中只有pottery填上去语义合适，由此确定G为答案。

第37题是：B

对应原文：F段：…explains Singh,‘it is essential that we obtain more climate data from areas close to the two great cities at Mohenjodaro and Harappa and also from the Indian Punjab.’

答案解析：题干中的further information与more climate data对应，vital与essential对应，而region则与具体的地点名称对应。从原文可以看出这段话是Singh说的，由此确定B为答案。

第38题是：A

对应原文：H段：Petrie believes…By investigating responses to environmental pressures and threats,we can learn from the past

答案解析：题干中“研究过去的行为模式可能拥有长久的好处”在28题已经考察过一次，因此只用寻找这些话是谁说的就好。而H段中只有Petrie一个人名，由此确定A为答案。

第39题是：D

对应原文：E段：Hodell adds:‘We estimate that the weakening of the Indian summer monsoon climate lasted about 200 years before recovering to the previous conditions,which we still see today.’

答案解析：水资源短缺的问题主要出现在E段。该段最后提到，印度夏季季风气候的减弱持续了大约200年。对应题干中approximate length of a period of water shortage。而这句话是Hodell说的，由此确定D为答案。

第40题是：A

对应原文：B段：‘There is plenty of archaeological evidence to tell us about the rise of the Harappan Civilisation,but relatively little about its fall,’explains archaeologist Dr Cameron Petrie

答案解析：B段开头就提到，“关于哈拉帕文明的兴起有许多考古证据，按关于它的衰落则证据较少”。对应题干中information…has been lacking，由此确定答案为A。
