  Question 31

  答案:protection

  定位原文:One is to… the other is for protection.

  解题思路:One is to provide warmth,提示下文即将讨论除了保暖之外的第二个主要的目的,定位到The other is for protection. 注意在One is…The other is…的结构之前,有一个概括的句子,是And there are - or were - two main reasons for having hair,main purposes是对main reasons的同义转述。

  Question 32

  答案:flexible

  定位原文:

  解题思路:…is composed mainly of a protein called keratin. This, by the way, is also found in fingernails,提示下文即将讨论keratin对于fingernails的作用。定位到In fact, it's keratin which makes them flexible,这里的them指的就是fingernails。main component是 be composed mainly 的同义转述;compose, 组成;component,成份。

  Question 33

  答案:elephants

  定位原文:… which is the equivalent of a couple of elephants.

  解题思路:but a full head of hair can support up to 12 tonnes,提示下文将讨论这头黑发相当于2个什么样的东西。定位到which is the equivalent of a couple of elephants。注意two是对a couple of 的同义转述。a couple of 有 “2个”和“若干”的意思。

  Question 34

  答案:100 000/100,000

  定位原文:There's some variation depending on hair colour but for an average adult the strand count is 100.000.

  解题思路:… but we do have quite a lot of hair to start with,提示下文将讨论人们有多少头发,定位到There's some variation depending on hair colour but for an average adult the strand count is 100.000。average number of strands是对for an average adult the strand count的同义转述。strand, 缕;variation,(数量、水平的)变化。

  Question 35

  答案:products

  定位原文:… a fortune is spent just on hair products. In the UK alone, consumers spend over five billion pounds each year on these.

  解题思路:I'd say the main importance of hair is the fact that it is big business. 提示下文将会讨论人们在美发方面的花费,定位到 a fortune is spent … each year on these。注意这里的these是hair products。这题有一定难度,是因为题目中的UK是在hair products后出现的。所以在听的过程中,听到hair products就马上记下来。large amount of money 是对a fortune的同义转述;fortune,大笔的钱。

  Question 36

  答案:cap

  定位原文:The bulb acts rather like a cap,it encloses the end of the hair in the head.

  解题思路:A single hair is fixed at one end below the skin in the bulb. 提示下文将具体讨论hair bulb,“发球”。定位到The bulb acts rather like a cap,it encloses the end of the hair in the head。end of hair follicle是对end of hair in the head的同义转述。follicle,毛囊。

  Question 37

  答案:oil

  定位原文:These produce oil which flows along the length of the hair and the health of the root determines the overall health of the strand of hair.

  解题思路:The next part of the hair is the root. This can be considered the control centre for each strand of hair and is where the glands are found. 提示下文将讨论glands含有的东西向发束提供什么。定位到These produce oil … health of the strand of hair。注意These指的是glands,supply 是对produce的同义转述;gland,腺体。

  Question 38

  答案:active

  定位原文:Fortunately, this is not active and I say 'fortunately' because otherwise it would be very painful to have your hair cut!

  解题思路:The last part is the shaft and this is the hair which is above the skin and is, of course, what we can see. 提示下文将会讨论shaft的特点,定位到Fortunately, this is not active … have your hair cut! 注意这句话的主语This指的是shaft。hair shaft, 发干。

  Question 39

  答案:skin

  定位原文:But whereas a change in your diet to, for example, eating unhealthy foods will soon be noticeable in your skin, changes to your hair will take a lot longer.

  解题思路:our diet - that is what we eat - is extremely important to the condition of our hair,提示下文即将讨论饮食对于发质的影响。定位到But whereas a change… in your skin, changes to your hair will take a lot longer. 注意whereas的使用目的,whereas引导了比较状语从句,是“然而,尽管”的意思,而且用了will soon be noticeable来与take longer to affect来作对比,所以听到skin就要马上记下来作为正确答案。noticeable,显著的。

  Question 40

  答案:blue(-)berries

  定位原文:

  解题思路:If you need a boost of vitamin C…提示下文即将讨论为头发提供维生素C的方法。定位到one of the best things to eat are blueberries. 注意题目中的“Vitamins C, D and E are all important for healthy hair”是对If 前的“There are a number of vitamins that are vital for good hair health”的同义转述;vital,至关重要的,维持生命所必需的。所以听到这句话之后,要马上要注意听下面的内容,一定是马上就要讲到维生素C的最佳来源了。blueberry,蓝莓;注意正确答案是复数blueberries。
