Dating from as far back as the 12th century, they are claimed to be the rarest historic buildings in western Europe. These buildings offer vital insight into Scandinavia's Viking past. But now, with only 30 wooden churches remaining [16] and their condition deteriorating, experts are working to preserve the structures for future generations.

Some of these spectacular churches are no more than small buildings, barely 4 meters wide and 6 meters tall. Others are much larger structures. They soar up to 40 meters into the cold air. [17] Most consist of timber frames that rest on stone blocks. This means that they have no foundations. Although many of the churches appear from the outside to be complex structures, they normally feature only a single storey but numerous different roof levels.

Staff from the Norwegian government have carried out conservation work on 10 of the churches over the past two years. Most of these churches date from between the 12th and 14th centuries. Other churches were conserved in previous years. So far, specialists have worked to add preservative materials to the churches' exteriors. They also replaced rotting roots and halted the sinking of the churches into the ground. In two cases, huge machines have been used to lift the buildings up to 30 centimeters into the air. This was accomplished so that the team could examine and repair the churches' original medieval stone blocks. The team plans to return to around a dozen of the buildings to assess progress and consider further action.

The earliest free-standing wooden church was probably built in Norway in around 1080. However, the largest known wooden churches were built from the 1130s onwards. This period was one of inter-elite rivalry, in which nobles sought to increase their influence by funding the construction of churches and other buildings. The reason for constructing the buildings from wood is probably that ideally proportioned straight and [18] slender timber was available in large quantities in Scandinavia's vast pine forests. As wood was so plentiful, it was cheaper to use than the stone used in the buildings of other European cultures. The area's ship building tradition, partly established by the Vikings, also meant that sophisticated carpentry was a major aspect of the local culture. The complex style of the medieval wooden church carvings and the skills used to make them almost certainly to derive from the ancient Viking tradition.

Q16. What does the speaker say about the Viking wooden churches?
Q17. What is special about most of the Viking wooden churches?
Q18. Why were the Viking churches constructed from wood?

本题问大多数维京木制教堂的特别之处。选项A 录音中未提及，故排除。录音中提到40米高只是部分教堂的高度，并非大多数维京教堂的特点，属于张冠李戴，故排除选项B。选项C与录音中的“这意味着它们没有地基” 一致，故为正确选项。选项D与录音中提到的“它们通常只有一层” 相矛盾，也排除。

本题问为什么维京人用木材建造教堂。选项C与录音中提到的“斯堪的纳维亚广阔的松树林中有大量曲直合适、粗细均匀的木材” 一致，故为正确选项。其余三项录音中均未提及，故排除。
