第4题：
Hair Care
Whether the hair is long or short,it must be regularly brushed and regularly washed.For greasy（油性的）hair , especially if the owner lives in a town , it may be necessary to wash the head every four to five days.Those with a dry hair can usually go a little longer,but this is a matter for the individual to decide.
As for style,this must be studied according to what is the latest fashion and also to suit the individual at different times of her life.If a woman is not able to go to hairdresser very often,it is important that she chooses a style she can easily manage for herself,and this nearly always means that the first cut must be very standard. The same applies to permanent waving（烫发）.I think that this should be carried out three or four times a year,so that the hair never gets out of hand.
One thing would be remembered though,that is,whatever you apply to the head can have some effect upon the skin and therefore anything strong should be used with care.Or you may use milder products.
Young people who has spots or skin troubles on their face should take particular care to ensure that the hair is both clean and does not come into contact with the affected piece of skin.Hair is very difficult to keep completely clean and therefore anyone running their hands through their hair and afterwards touching their face,or letting their hair fall over their faces,might spread in- fection from one place to another.
Good hair does a lot to the effect of a face,so if you want to look charming,please start with your hair.
A: having the hair done three or four times a year
B: following the latest fashion to suit one's age
C: not combing the hair with hand
D: not applying anything strong to the head
文中第二段提及有关发型的问题“As for style , this must be studied according to what is the latest fashion and also to suit the individual at different times of her life.”就发型来讲，我们必须参考最流行的时尚，并且还要适合她在不同年龄段的个人特点。所以正确答案是B。
文中第三段提及有关护发产品的问题。首先文章告诉我们任何护发产品都对头发有影响，这就暗示我们使用的时候应该小心，并且由此可以否定选项B。但并不是特别柔和（extremely mild)的产品就是对头发有效的产品，比如油性发质的人也许不适于使用这种产品，由此可以否定C。选项D文中没有提及。所以正确答案是A。
保持脸部绝对清洁（选项A）和频繁地清洗头发（选项B）都是太极端、不符合实际情况的说法。文章最后一段提及“Hair is very difficult to keep...might spread infection from one place to another.”就是说最好不要用手梳理头发之后再去触摸脸，这样会引起感染。因此正确答案是D。
从文章给我们提及的信息来看，go这里的含义与上一句紧密相连，在go之前有一个隐含的主语：“洗发的频率”。因此正确答案是C。
