雅思阅读考试里的一些细节中可能包含了重要的信息来帮助我们理解内容，比如雅思阅读文章中有些标点符号隐藏了重要信息，大家在阅读过程中需要注意一下。
Developed most probably as a defense against forest fires, the bark of the cork oak has a particular cellular structure — with about 40 million cells per cubic centimeter — that technology has never succeeded in replicating.
摘自paragraph 2
这句话破折号起到句中停顿作用，补充解释"a particular cellular structure"，去掉这个补充成分，此句要说明的是软木作为木材有抵御森林火灾的天然优势，而人类技术从未能企及。
对应地，后面的判断题目scientists have developed a synthetic cork with the same cellular structure as natural cork.(Question 2) 题目说“科学家已经研发出合成软木，跟天然橡木有相同的纤维质地(也就是防火的特点)”，显然题目与原文矛盾，判定为false。
If the bark is stripped on a day when it's too cold — in when the air is damp— the tree will be damaged.
摘自paragraph 4
此句说“如果在寒冷或潮湿的日子里剥树皮，树会遭损伤”，通过"if"可以看出是讲“条件”，对应到后面一判断题：Cork bark should be stripped in dry atmospheric conditions.(Question 4)
此题就在讲剖树皮的条件，显然干燥与“潮湿”(damp)矛盾，判定false. 这里有个小插曲，有的童鞋不认识damp一词，恐怕只好通过语境猜词义，前面说cold，搭配一起是“寒冷干燥”还是“阴冷潮湿”，这里就得想想出题的是英国人，恐怕他们字典里很难找“寒冷干燥”吧，于是这是潮湿的意思。
The Montreal study
Participants, who were recruited for the study through advertisements, had their brain activity monitored while listening to their favorite music. It was noted that the music stimulated the brain's neurons to release a substance called 27 _______ in two of the parts of the brain which are associated with feeling 28________.
Researchers also observed that the neurons in the area of the brain called the 29_______ were particularly active just before the participants' favourite moments in the music - the period known as the 30_______. Activity in this part of the brain is associated with the expectation of 'reward' stimuli such as 31_______.
Question27-31
考题：摘要填空
这组考题可谓把标点符号用到极致，从空格考点来看，五道题目有三题明显考术语(往往有引号)，而最后一空前“reward”作为术语可以容易定位到。
如此，在利用标题定位段落后，找到一两段话中的术语，题目就迎刃而解。具体来看，空格27考一种物质(化学物质名称，早在剑桥4里就已经出现过类似考察)substance往往就指hemical。空格29考的是大脑区域的名称，空格4考的是“时间段或阶段'名称，空格31考察举例名称，但给出有引号的术语来定位。
原文
The first thing they discovered is that music triggers the production of dopamine — a chemical with a key role in setting people's moods— by the neurons(nerve cells) in both the dorsal and ventral regions of the brain.
摘自paragraph 2
此处对应的是空格27 主要的提示信号仍是破折号，起到补充解释dopamine的作用，于是此处答案即使dopamine。
What is rather more significant is the finding that the dopamine neurons in the caudate — a region of the brain involved in learning stimulus— response associations, and in anticipating food and other 'reward' stimulus — were at their most active around 15 seconds before the participants' favorite moments in the music.
摘自paragraph 3
此句中破折号再次起到信号作用解释caudate是大脑中的一个区域，于是空格29答案便是这个词，而另一处破折号前出现空格31的定位词reward stimulus，于是它对应的举例就是空格5 food。
The researchers call this'anticipatory phase' and argue that the purpose of this activity is to help us predict the arrival of our favorite part.

摘自paragraph 3
紧接着一句中提到的这一术语正是空格30的答案，如果词汇量充分，也很容易理解anticipate本来就与predict和before对应到，phase指时期或阶段，可以对应period。
