10、roposalD) contribution题目详解：先解标题：Biological (和biology的名词，生物; biological生物的) Identification (是identify的名词，意思是辨认、识别)Technologies(是technology的复数形式，意思是技术，这是理工类考生必须掌握的单 词!)第一段：1.When(当) a person walks(走路), the movement(运动) of his head, trunk(躯干), hipbones(股骨) and limbs(肢体) are all reflected (反映、反射，是被动语态)i
11、n changes(变化) in his body.2.A computer 1 these changes into a database(数据库).A) checks：v 检查、核实B) stores储备、储存C) revises修订、校对D) modifies修改、变更分析：从上下文的意思判断，作者说的是往数据库里存储肢体的变化的资料。存储的英语词是 store，所以要选 B.3.Later(以后、后来), the computers can 2 identify(本文的核心词汇，请注意它各种词型的变化，识别、辨别) him according to(根据) these changes.
12、A) nearly：几乎、差不多B) approximately：大约C) roughly：粗略地D) accurately：准确地分析：我们发现所给四个都是副词，如果没有前后文的话，填哪个都是通的。但正确答案只能有一个。到底怎么填，还得“瞻前又顾后”。特别当我们看到在第四句里有quickly时，基本可以判断答案应是D。即，既准确又迅速。4.This is a new biological(生物的) identification(识别) method(方法) and it can quickly(迅速地) identify(识别) an examinee(被检测者) 3 disturbing
13、(打扰)him.A) without：介词，没有B) with：介词，带有，是without 的反义词。C) for：为了D) in：在。方面分析：前面句子说这是一项新的生物的辨认技术，最后一句说，这项新技术适合机场和超市使用。以此推论，这是个好的技术。不仅能识别人而且还不打扰人。所以我们应该选择A。如果不能完全肯定，可以把答案填入空格后再读前后的句子。看看语意是否吻合上下文。5.It's especially(尤其) suitable for(适合。) use(名词，使用) in airports(机场) and supermarkets(超市).分析：这个句子没有留空，就是希望大家
14、能根据它的意思来检查前面的空格是否正确。所以别忽视!第二段：6.Everybody's(每个人的) voice(声音) is 4 .A) identical：完全一致的B) similar：相似的C) unique：独特的、独一无二的D) sole：唯一的、单独的分析：根据常识每个人的声音应该具有独特性和惟一性， 不可能两个人声音完全一样所以，选项 C 是最合适的用词，因此它是答案。大家也可以继续向后看，下面的第八句中的different恰好能证明我的选择是正确的。7.When a person's voice is recorded(被录音) by an instrument
15、(仪器), its voice frequency(频率) spectrum(频谱) is called(被称做)his sound print(声纹).8.Like(介词，像) a fingerprint(指纹), everybody's sound print(印痕) is different.9.How(如何) can computers 5 his sound?A) hear：听见B) understand理解、明白C) distinguish区分D) record录音、记录分析：这一题如果一时不能确定，可以先看后面几句，因为后面的几句话是这句话的答案，只有答案和问题对上了，才
16、能说选项是正确的。用逆推的方式可以推断出答案。其它三个选项提供的词都不正确。10.First(首先), his voice is recorded(被记录下来), which(引导定语从句，指代前面一句话) allows(允许) the computers to become familiar with (熟悉。)his voice.请记住：allow sb to do sth允许某人做某事; be familiar with sth/sb对。熟悉11.It will then(然后) turn(将。转换成。) his sound characteristics(特征) into a 6 of
17、 digits(数码，数字).A) series系列B) package包、捆C) line行D) pair对、双分析：通过搭配关系，我们可以确定应该是a series of digits.所以选择A。请注意下列用法：a series of accidents一系列意外事件; a package of books一包书; a line of trees一行树; a pair of chopsticks一双筷子词组：turn A into B将A转换成B.12.These digits represent(代表) the frequency(频率), pitch(音高) and rhythm (
18、节奏)of the persons voice.13.These are the 7 on which (介词+which是定语从句的一种形式)the computers can distinguish(区分) his voice from 8 .7. A) origin：起源、由来B) cause起因C) reason原因、理由D) basis基础、根据8. A) others别的B) anothers另一个的C) each others彼此的D) one anothers一个另一个的分析7：要解出这题，只需要搞清楚在on which中，which应该是所给四个选项中的哪一个即可。通常情况下
19、，of origin; for cause; for reason; on the basis(在。基础上， 根据。)，所以答案应是D。如：1. We dont know the origin of life on the earth.我们不知道地球上生命的起源。2. What was the cause of the fire? 火灾的起因是什么?3.You dont have any reason for being late for school.你没有迟到的理由。4.We can develop our friendship on the basis of trust. 我们可以在信任
20、的基础上发展我们的友谊。分析8：句子的意思是，电脑能够将他的声音与另一个人的声音区分开来。根据不定代词的用法，只能选择B。如： I cant distinguish his handwriting from others(anothers )我无法将他的笔迹同其他人的区分开来。第三段：14.When that person needs(需要) to be identified(被识别), after(在。之后) he says(说) only one word(一个字) or two(两个字), the computers can identify him.15.The computers c
21、an even(甚至) identify sounds coming 9 the wires(电线).A) at在。旁边B) on在。上面C) in在。里面D) through介词，通过、穿过分析：句子的意思是，电脑甚至能够识别通过电线传过来的声音。through 是合理的选择。所以，D是答案。如：The man got in the room through the windows.这个男人通过窗户进了房间。2Where Did All the Ships Go?The Bermuda Triangle is one_1_the greatest mysteries of the sea.I
