　　Q20

　　Interesting finds at an archaeological site

　　Organic materials such as animal skins and textiles are not discovered very often at archaeological sites. They have little protection against 20..............., which means that they decay relatively quickly. But this is not always the case. If temperatures are low enough, fragile artefacts can be preserved for thousands of years.

　　分析

　　题干中可以划定位词的有题目标题的an archaeological site和题干中的organic materials, animal skins and textiles, temperatures和thousands of years。空格前面是protection against, 所以空格应该写一个有破坏力的名词，这句中的little【很少】是个否定词，在原文中要有对应的信息。

　　定位

　　B Organic materials like textiles and hides are relatively rare finds at archaeological sites. This is because unless they’re protected from the microorganisms that cause decay, they tend not to last long. Extreme cold is one reliable way to keep artefacts relatively fresh for a few thousand years, but once thawed out, these materials experience degradation relatively swiftly...

　　答案

　　上文第 一句中出现了Organic materials，textiles and hides。第二句中的that cause decay意味着这个短语修饰的词microorganisms是有破坏力的名词，所以答案是microorganisms。这句中的unless...they don’t last long对应题干中的little。

　　Q21-22

　　A team of archaeologists have been working in the mountains in Oppland in Norway to recover artefacts revealed by shrinking ice cover. In the past, there were trade routes through these mountains and 21...............gathered there in the summer months to avoid being attacked by 22...............on lower ground. The people who used these mountains left things behind and it is those objects that are of interest to archaeologists.

　　分析

　　题干中可以划定位词的有a team of archaeologists, mountains in Oppland in Norway, in the past, trade routes, summer months, lower ground。

　　21题空格前面是mountains，21题后边是gathered，这两句的句型不一样，所以and后边的句子需要主语，又因为空格后边是谓语动词，所以这个主语只能放在空格里。21题后边的gathered【聚集】，所以空格应该写一种动物。

　　22题前面是avoid being attacked by，所以空格应该也是一种动物。

　　定位

　　C Over a nine-year period, a team of archaeologists, which included Lars Pilo of Oppland County Council, Norway, and James Barrett of the McDonald Institute for Archaeological Research, surveyed patches of ice in Oppland, an area of south-central Norway that is home to some of the country’s highest mountains. Reindeer once congregated on these icy patches in the later summer months to escape biting insects, and from the late Stone Age**, hunters followed. In addition, trade routes threaded through the mountain passes of Oppland, linking settlements in Norway to the rest of Europe.

　　答案

　　上文第 一句出现了a team of archaeologists ，Oppland，mountains。第二句中的congregate【聚集】对应题干中的gathered，所以21题答案是reindeer。

　　这句后半句中的to escape biting对应22题题干中的to avoid being attacked by，所以答案是insects。
