剑桥雅思17听力第四套题目第四部分由10道提纲型填空题组成。整体难度虽然较大，但更令人迷惑的是前四道题的排版，让人很难知道录音到底是横着来的还是竖着说的，听起来十分杂乱。
剑桥雅思17 Test4 Part4听力答案解析
第31题答案：golden
对应原文：Maple syrup is a thick,golden,sweet-tasting liquid that can be bought in bottles or jars
答案解析：这道题的答案藏得比较隐蔽，golden既没有明显的提示词，也没有重读，只能根据题干，事先判断出空上应该填某种颜色，进而锁定它。
第32题答案：healthy
对应原文：it provides a healthy alternative to refined sugar.
答案解析：这道题同样具有一定的难度。从题干可以推断出空上应该一个形容词，听到refined sugar之后通过回想锁定healthy。
第33题答案：climate
对应原文：I mean all parts of Canada,and the other is the north-eastern states of North America.In these areas,the climate suits the trees perfectly.
答案解析：这道题采用语序颠倒的手法，先说的conditions,Canada和North America，最后才说的climate，很容易让人怀疑答案是否已经过去了。不过只要足够耐心，climate读的还是很明显的。
第34题答案：rock(s)
对应原文：they didn’t have storage facilities in those days–they boiled the liquid by placing pieces of rock that had become scorching hot from the sun into the sap.
答案解析：同样是语序颠倒的手法，将空前提示词hot放在答案之后，比较考验大家的短期记忆能力。
第35题答案：diameter
对应原文：The trees have to be well looked after and they cannot be used to make syrup until the trunks reach a diameter of around 25 centimetres.This can take anything up to 40 years.
答案解析：听到trunks意识到答案即将到来。录音中虽然没有空前词correct的明显替换，但根据词性筛选之后发现只有diameter填上去语义合适，由此确定其为正确答案。
第36题答案：tube
对应原文：this involves drilling a small hole into the trunk and inserting a tube into it that ends in a bucket.
答案解析：drill提示大家答案即将到来。从题干可以推测出来自老烤鸭雅思空上应该填一个名词，筛选之后发现只有tube填上去语义合适，由此确定其为正确答案。
第37题答案：fire
对应原文：These are basically extremely large pans–the sap is poured into these,a fire is built and the pans are then heated until the sap boils.
答案解析：听到large pans意识到答案即将到来，根据空前词a锁定fire。
第38题答案：steam
对应原文：The evaporation process creates large quantities of steam
答案解析：这道题比较简单一些，空前修饰词a lot of对应large quantities，由此确定steam为正确答案。
第39题答案：cloudy
对应原文：After this process,something called‘sugar sand’has to be filtered out as this builds up during the boiling and gives the syrup a cloudy appearance and a slightly gritty taste.
答案解析：sugar sand提示大家答案即将到来，从题干可以推测出空上应该填一个形容词，而且跟模样有关，由此锁定cloudy。
第40题答案：litre/liter
对应原文：It takes 40 litres of sap to produce one litre of maple syrup so you can get an idea of how much is needed!
答案解析：根据40 litres与a huge quantity的对应锁定答案所在句子，空前词a被替换成one，由此确定litre为正确答案。
