剑桥雅思12 Test8 Passage1阅读答案解析

第1题答案：obsidian

对应原文：第1段： Historians have discovered that a type of natural glass — obsidian — was first used as tips for spears.

答案解析：由于整篇文章按照时间顺序进行写作，根据题干中的early humans，我们可以直接定位到第1段。通过空前词called判断答案应该为一个学术名词，由此确定obsidian。

第2题答案：spears

对应原文：第1段：… was first used as tips for spears.

答案解析：顺着上一题玩下，sharp points与tips同义替换，由此确定答案为spears。

第3题答案：beads

对应原文：第1段：Archaeologists have even found evidence of man-made glass which dates back to 4000 BC; this took the form of glazes used for coating stone beads

答案解析：根据4000 BC定位到这两句话，题干询问由石头制成的某种东西，根据修饰关系锁定beads。

第4题答案：impurities

对应原文：第2段：… from the first century BC. The glass made during this time was highly coloured due to the impurities of the raw material.

答案解析：根据First century BC定位到这两句话，题干上because of与原文中due to同义替换，由此确定答案为impurities。

第5题答案：Romans

对应原文：第2段：The secret of glass making was taken across Europe by the Romans during this century … it was not until their empire collapsed in 476 AD

答案解析：根据476 AD定位到第2段的这句话。从原文看出，答案应该是文中their所指代的内容。由此往前寻找，确定答案为Romans。

第6题答案：lead

对应原文：第3段：… George Ravenscroft (1632—1688). He attempted to counter the effect of clouding that sometimes occurred in blown glass by introducing lead to the raw materials used in the process.

答案解析：顺着上一题往下，根据1632-1688与17th century的对应定位到这句话。空前词using与introducing同义替换，由此确定答案为lead。

第7题答案：clouding

对应原文：第3段：He attempted to counter the effect of clouding that sometimes occurred in blown glass

答案解析：这道题与上一道题在原文中的顺序正好相反。题干中avoid与原文中counter同义替换，由此确定跟答案为clouding。

第8题答案：taxes

对应原文：第4段：In Britain, the modern glass industry only really started to develop after the repeal of the Excise Act in 1845. Before that time, heavy taxes had been …

答案解析：根据1845与Mid-19th century的对应定位到这句话。laws与Act同义替换，但从这句话中看不来法律具体有什么有关。直到下一句，“在那之前，玻璃制造被征以重税”。可知该法律是关于税收的，由此确定taxes为答案。

第9题答案：TRUE

对应原文：第5段：factory-owner HM Ashley introduced a machine … more than three times quicker than any previous production method.

答案解析：原文中提到HM Ashley的机器比之前使用的任何方法都要快不止3倍。可见它确实是当时最快的，由此判断答案为TRUE。

第10题答案：FALSE

对应原文：第5段：Michael Owens — founder of the Owens Bottle Machine Company

答案解析：Michael Owens是该公司的创始人，而非雇员。由此判断答案为FALSE。

第11题答案：NOT GIVEN

对应原文：无

答案解析：文章最后一段只是提到玻璃制造是门大生意，但找不到任何跟生产商有关的内容。题目属于无中生有，由此确定答案为NOT GIVEN。

第12题答案：TRUE

对应原文：第7段：with growing consumer concern for green issues, glass bottles and jars are becoming ever more popular

答案解析：原文中提到，随着消费者对环境问题越来越关心，玻璃制成的瓶瓶罐罐也受到更多的欢迎。两者确实存在因果关系，由此确定答案为TRUE。

第13题答案：FALSE

对应原文：第7段：As less energy is needed to melt recycled glass than to melt down raw materials, this also saves fuel and production costs.

答案解析：原文中提到，融化回收的玻璃比融化原材料所需要的能量要少，可以节省燃料和生产成本。即生产回收玻璃更省钱。题干描述与此相反。由此确定答案为FALSE。
