参考解析
解析：
结构应题。句意：所有的哺乳类动物都有毛发，但并不明显。but是转折连词，后面引导的应该是一个句子，而且句子主语应是指代前面所提的整个内容，而不是前句中的all mammals；所以主语应用it。B项中应该是否定，因此只有选项A是答案。

共用题干Hair CareWhether 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. The thing you wash your hair with must be______.A: used with careB: very strongC: extremely mildD: fashionable

共用题干第二篇Lawrence CurryWhen I tell people my name,they always ask me if I'm related to Lawrence Curry,the novelist,and when I say,yes,he was my great-uncle,they always want to know what he was like. "We've read all his books,"they say,"but please tell us what he was really like."When I described him,as I knew him,they go disappointed.It seems that they find it difficult to accept such a great figure could have had such an ordinary character.My great-uncle was tall,with a long thin body.When he walked,he moved stiffly,with his arms clamped against his sides,looking like nothing so much as a pair of scissors.When I knew him,his hair as quite white,though it was supposed to have been yellow when he was young. His eyes were blue and deep set and had an anxious look about them as if he found the world a puzzling place.This expression of anxiety,which arose from nothing more than short-sight一he refused to wear glasses一inspire the protective instincts of his lady admirers,much to the irritation my great-aunt who thought all women were fools,except herself.Great-uncle Curry was naturally lazy. He spent a great deal of his time in the village pub playing darts.He was also a compulsive reader from the local telephone directory to great-aunt's shopping lists.For a man whose book showed such a deep perception of the complexities of human behavior, his conversation was surprisingly trivial.He delighted in discussing English weather,the price of beer,his grandchildren's most amusing words.He loved gossip,but he was kind.I never heard him make a malicious remark,but the wisdom of his writing never appeared in his conversation.As a child,we much preferred the company of his cousin,Stanly,who was a successful shop-owner who always brought us bags of sugar and broken biscuits.Taking it all in all,I have to admit my famous great-uncle was rather a bore.My great-uncle always had an anxious expression because_________.A:he found the world a confusing placeB:he was always thinking complex thingsC:he didn't have a good eyesightD:he was worried about what was going to happen to him
