20.We already have iris(虹膜) and fingerprint scanning but noses could be an even better method of identification,says a study from the University of Bath,UK.
The researchers scanned noses in 3D and characterized them.They found 6main nose types:Roman,Greek,Nubian,hawk,snub and turn-up.Since they are hard to hide,the study says,noses would work well for identification.
The researchers say noses have been overlooked in the growing field of biometrics,studies into ways of identifying distinguishing characters of people."Noses are out standing facial features and yet their use as a biometric has been largely unexplored,"said the University of Bath's Dr Adrian Evans."Ears have been looked at in detail,eyes have been looked at in terms of iris recognition but the nose has been ignored."
The researchers used a system called PhotoFace,developed by researchers at the University of the West of England in Bristol,for the 3D scans.
Several measurements by which noses can be recognised were identified and the team developed recognition software based on these parameters(范圍)
"This initial work is nowhere as good as iris identification but the nose has pros and cons,"said Dr Evans.
There's no magic biometric that solves all your problems.Irises are a powerful biometric but can be difficult to get accurately and can be easily covered by eyelids or glasses.People can easily cover up their ears,with their hair for example.
"Of course you can have a broken nose or wear a false nose or have plastic surgery but to have nose surgery to change your identity is fairly obvious.Irises are very good for recognition but you can put in dilation drops which change the iris completely.Not all techniques are reliable,"he said.
The research is based on a study of 40noses and the data base has now been expanded to 160for further tests to see if the software can pick out people from a larger group and distinguish between relatives.
Dr Evans hopes the method can be proven to be effective on this larger sample."The technique certainly shows potential,perhaps to be used in combination with other identification methods,"he said.

分析 文章講述了一種新的身份識別方法,通過鼻子來鑒定身份.目前廣泛采用的身份識別方法有虹膜識別,指紋識別等,但鼻子識別身份的方法還沒有得到充分利用.英國的研究小組對這種方法進行了開發(fā),其效果還有待進一步測試.
解答 答案:57.B 推理判斷題.文章講述的是通過鼻子來鑒定身份的方法,是最新的科技報道,應該是科技類的文章.故選B.
58.D 細節(jié)判斷題.文章第五段說Several measurements by which noses can be recognised were identified and the team developed recognition software based on these parameters研究小組開發(fā)了一款通過鼻子識別身份的軟件.故選D.
59.D 猜測詞意題.文章第三段說Ears have been looked at in detail,eyes have been looked at in terms of iris recognition but the nose has been ignored耳朵,眼睛用于識別身份都得到了研究,但鼻子的識別方法被忽略了.故選D.
60.A 推理判斷題.文章最后兩段說The research is based on a study of 40noses and the data base has now been expanded to 160for further tests to see if the software can pick out people from a larger group and distinguish between relatives目前已鼻子鑒定身份的數(shù)據(jù)庫還存在不足,效果還需要進一步測試.故選A.
點評 閱讀理解是考查語篇理解能力.常考的題型有:推理判斷題;主旨大意題;細節(jié)理解題;猜測詞意題.近幾年又出現(xiàn)了兩種新的考查方式:寫作態(tài)度判斷題和文章結(jié)構(gòu)題.解題時,在讀懂文章的基礎(chǔ)上,還有特別注意掌握題型的特征,尤其是細節(jié)題和推斷題不可混淆:細節(jié)題是文章信息的再現(xiàn);推斷題是文章信息的提。绢}是廣告類文章,考查主要是以細節(jié)題為主,細節(jié)題要注意常用的出題陷阱有:夸大,縮小,張冠李戴,偷梁換柱,無中生有等,做題時要看清看準.
