现代塑料的诞生

剑桥雅思5 Test 2 Passage 1阅读答案解析

第1题答案：candle wax

对应原文：第2段：which means that,like candlewax,they melt when heated and can then be reshaped

解析：因为是第1题，所以直接从文章开头找起，发现第1段主要是在介绍人物，跟塑料没有太大关系，于是将目光投向第2段。similiar way与like同义替换，由此确定答案为candle wax

第2题答案：synthetic

对应原文：第2段：Bakelite had the distinction of being the first totally synthetic thermosetting plastic.

解析：顺着上一道题目往下，根据first定位到具体句子，题干中的entirely与原文中的totally同义替换，由此确定答案为synthetic

第3题答案：chemistry

对应原文：第三段：immense technological progress in the domain of chemistry

解析：上一题结束之后来到第三段，根据advance和progress的对应确定具体的句子。题干中field与空构成所有格结构，而field在原文中又与domain替换，因此确定答案为chemistry

第4题答案：Novalak

对应原文：第5段：…combined under vacuum inside a large egg-shaped kettle.The result was a resin known as Novalak

解析：根据题干中上一步的vacuum和这一步的resin定位到这一句，题干中的called与原文中known as同义替换，由此确定答案为Novalak

第5题答案：fillers

对应原文：第5段：Other substances were then introduced:including fillers,such as woodflour,asbestos or cotton

解析：根据cotton,asbestos定位到这一句，题干中问这两样物品是什么的举例，由此确定答案为fillers

第6题答案：hexa

对应原文：第5段：hexa,a compound of ammonia and formaldehyde which supplied the additional formaldehyde necessary to form a thermosetting resin

解析：根据题干中的ammonia和formaldehyde定位到这一句话。由题干图形可知文章来自 雅思问的是这两种物质混合之后是什么，由此确定答案为hexa

第7题答案：raw

对应原文：第5段：This resin was then left to cool and harden,and ground up a second time.The resulting granular powder was raw Bakelite

解析：根据cool,hardened,powder定位到这句话。题干中空对Bakelite起修饰作用，根据这一修饰关系很容易确定答案为raw

第8题答案：pressure

对应原文：第5段：In the last stage,the heated Bakelite was poured into a hollow mould of the required shape and subjected to extreme heat and pressure

解析：空与heat存在并列关系，而heat在原文中直接原词出现，很容易锁定答案为pressure

第9题答案：B

对应原文：第6段：Moulds had to be carefully designed so that the molten Bakelite would flow evenly and completely into the mould

解析：这道题采用词义解释的方式将ease替换为evely and completely，fill又和flow into对应，因此确定B为正确答案。

第10题答案：C

对应原文：第6段：The object could not be designed so that it was locked into the mould and therefore difficult to extract.

解析：选项A，D都属于完全没有提到的内容，E选项并不是影响设计的因素，反而是设计的结果。C选项中remove与extract同义替换，由此确定答案。

第11题答案：TRUE

对应原文：第4段：On 13 July 1907,Baekeland took out his famous patent describing this preparation,the essential features of which are still in use today.

解析：根据1907定位到第1段和第4段，发现第1段中的内容与题干稍有偏差，因此主要将注意力集中在第4段。题干中的modern与today同义替换，principles与features对应，即题干中的所有信息点在原文中都能找到根据，由此确定答案为YES

第12题答案：FALSE

对应原文：第7段：Baekeland’s invention,although treated with disdain in its early years,went on to enjoy an unparalleled popularity

解析：原文中Baekeland的发明一开始被轻视，后来才受到广泛欢迎，这与题干中的immediately冲突，因此确定答案为FALSE

第13题答案：FALSE

对应原文：第7段：consumers everywhere relished its dazzling array of shades,delighted that they were now,at last,no longer restricted to the wood tones and drab browns of the pre-plastic era

解析：原文中说这种材料有各种各样的颜色，人们再也不用受制于木色和棕色。这与题干中的only冲突，因此确定答案为FLASE
