2013年职称英语考试资料---Biological Identification Technologies
When a person walks, the movement of his head, trunk, hipbones and limbs are all reflected in changes in his body. A computer 1 these changes into a database. Later, the computers can 2 identify him according to these changes. This is a new biological identification method and it can quickly identify an examinee 3 disturbing him. It's especially suitable for use in airports and supermarkets.
Everybody's voice is 4 . When a person's voice is recorded by an instrument, its voice frequency spectrum is called his sound print. Like a fingerprint, everybody's sound print is different. How can computers 5 his sound? First, his voice is recorded, which allows the computers to become familiar with his voice. It will then turn his sound characteristics into a 6 of digits. These digits represent the frequency, pitch and rhythm of the person’s voice. These are the 7 on which the computers can distinguish1 his voice from 8 .
When that person needs to be identified, after he says only one word or two, the computers can identify him. The computers can even identify sounds coming 9 the wires. This will provide a 10 guarantee to electric banks and electric purchases.
We often bring ID cards2, work cards, or driver licenses with us to prove our identity. If all these cards are forgotten or lost, how can we prove 11 we are? In fact, it's not difficult to prove whom you are, because your body 12 has identifying markers. Some are physiological features, such as fingerprints, sounds, facial types and eye color. The computer can help to identify you. Suppose your features have already been stored in the database3. To identify you, we have to take your picture with a camera and send it to a computer for 13 . First, the computer needs to reposition this picture according to the position of your eyes4, and then starts to read the message of your physiological features such as the 14 of your pupil5 to the whites of your eyes6 and the shape of his nose. Next, it seeks matching records from the database. Finally, it makes a 15 .

完型填空答题思路：
1. 分析文章标题， 了解文章主题， 确认文章主题词;
2. 对比被选项， 推测答案可能出现的范围;
3. 关注空格两端结构，借助空格所在的局部搭配结构及搭配语意判断答案;
答案与解析：
1. 分析文章主题：
Biological Identification Technologies
文章主题词：biological identification(生物鉴别), technology(技术)
2. 直接解题：
When(在...的时候) a person walks(步行), the movement (运动)of his head(头， 领袖， 朝向，作为...的首领), trunk(躯干，树干), hipbones (髋骨)and limbs(四肢) are all reflected (反射)in changes(变化) in his body(身体).
1. A)checks(检查，核对，制止，支票) B)stores(存储， 商店，储备)
C)revises (校订, 改变) D)modifies (更改，修改)
A computer(计算机) 1 these changes into(到...里面， 进入...状态) a database(数据库， 资料库).
1. B 空格所在的句子说“计算机...这些变化到资料库里”，依据该句判断B(存储)是答案。
考点：常见动词的辨别。
2. A) nearly (几乎) B)approximately (近似地)
C)roughly(粗略地，粗暴地) D) accurately(精确地，正确地)
Later(稍后，随后，更迟的), the computers can 2 identify(识别) him according to (根据)these changes.
2. D 空格所在的句子说“随后， 计算机能根据这些变化...识别出他”， 依据该句判断D(accurately 准确地) 符合逻辑。
考点：常见副词的辨析。
3. A) without(没有，不) B)with(有，用， 同...,由于..., 赞成)
C) for (为了， 因为， 适合于)D) in(在...之中， 在...期间，穿着， 进入)
This is a new biological identification method(方法) and it can quickly identify(识别) an examinee(被检查者，应试者) 3 disturbing(弄乱, 打扰) him.
3. A 选项A和B是正反义词，因此首先重点关注(提示1：有关系的被选项可能是答案)。空格所在的句子说“这是一项新的生物学辨认技术， 它能很快地识别出被监测者...打搅他(指被检测者)”，由此判断without(不)应该出现在空格中， 表达“能辨认人而又不去打搅 (without disturbing) 被辨认人”。
考点：常用介词的基本用法。
It's especially(尤其) suitable for (适合)use(使用) in airports(机场) and supermarkets(超市).
4. A)identical(同样的，完全相同的) B) similar(相似的)
C) unique (独特的,唯一的) D) sole(唯一的， 仅有的)
Everybody's voice is 4 .
4. C 根据常识 --- 每个人的声音具有独特性。Sole通常只能用作定语， 而不用作表语，因此选项 C 的 unique(独特的， 唯一的)是答案。
考点：近义形容词的辨析。
When a person's voice(声音，意见， 表达) is recorded by (被...纪录)an instrument(工具， 仪器，乐器), its voice frequency spectrum (频谱)is called (被称作为...)his sound print(印刷， 出版， 印迹) .
Like(象，如同， 喜欢， 希望) a fingerprint(指纹), everybody's sound print(声音印迹) is different(不同的).
5. A)hear(听到，听见) B) understand(理解)
C) distinguish(区分，辨别) D) record(记录， 录音)
How can computers 5 his sound?
5. C Distinguish(辨别) 是文章主题词identify(识别)的近义词，因此C很可能是答案(提示2：出现文章主题词或出现与文章主题词呼应的近义词/家族词汇的选项可能是答案)。 空格所在的句子说“计算机怎样才能...他的声音?”，由此排除B(理解)， 接下来的句子说“首先， 他的声音被记录下来， 这允许计算机熟悉他的声音”， 由此排除A(听见)， D(记录)， 因此C是答案。
考点：文章主题词。
First(第一， 首先), his voice is recorded(被记录), which allows(允许) the computers to become familiar with (熟悉)his voice.
6. A)series(系列，连续) B)package (包裹 )
C)line (线，绳子，线路， 排成一行 ) D)pair(一对，一双)
It will then turn his sound(声音) characteristics(特征， 特有的) into (把...转变成...)a 6 of digits(阿拉伯数字) .
6. A 空格所在的局部结构说“一...的数字”， a package of (一箱的)、a line of (一行的)、a pair of (一双的) 与 digits(数字) 都不搭配， 只有a series of digits (一系列数字) 最合适。
考点：常见量词。
These digits(数字) represent(代表，象征) the frequency(频率), pitch(音高，(建筑的)倾斜度，投， 掷) and rhythm(节奏， 韵律) of the person’s voice.
7. A) origin(起源) B)cause (原因，引起)
C) reason (原因，推理， 劝说) D)basis(基础，根据)
8. A)other’s (应为others’) B)another’s (另一个(人)的)
C)each other’s(彼此的) D)one another’s (彼此的)
These are the 7 on which the computers can distinguish his voice from (区分...和...) 8 .
7. D Which 引导定语从句， which 指代空格处的词语，which前出现了介词on， 这意味着空格处的词语应该能与介词on搭配使用， 被选项中只有 basis 能与介词 on 搭配，组成 on this basis (在此基础上)。其它三个选项的词均不能与on搭配。
考点：定语从句， 固定搭配短语结构on the basis (of)(在...的基础上)
8. B 被选项C和D是近义词词组， 因此彼此排除掉。选项A错误， 正确的表达方式应为“others’/其他(人)的”， 因此答案为B。 其实空格前的his voice泛指“某个人的声音”, 相当于one’s voice,与选项B中的(another’s)形成呼应结构。
考点：代词his的指代内容， 短语结构：one...another...(一个...,另一个...)
When(在...的时候) that person needs(需要) to be identified(被识别), after(在...之后) he says only(仅仅， 唯一的) one word(词，消息) or two, the computers can identify(识别) him.
9. A)at B) on(在...之上，靠近， 在...的时候， 关于)
C) in D) through(穿过， 通过， 凭借)
The computers can even identify(识别) sounds(声音) coming 9 the wires(电线，金属丝).
9. D “空9”所在的局部搭配结构说“sounds coming ...the wires/...电线而来的声音”, 显然through(通过) 是合理的选择。所以D是答案。
考点：常见介词的常用法。
10. A) cleverer(更聪明的) B) tidier(更整齐的， 更整洁的)
C) smarter(更聪明的， 更漂亮的， 更迅速的) D) safer(更安全的)
This will provide(提供， 规定， 预防) a 10 guarantee (保证)to electric banks (电子银行)and electric(电的， 电动的) purchases(购买).
10. D 被选项A和C互为近义词， 因此在“更聪明的”这层词义上彼此排除掉。空格处的形容词作定语修饰名词guarantee(保证) ，由此排除B(搭配不通顺)， 答案只能使D：safer guarantee (更安全的保证) 最合理。
考点：常见形容词的辨析。
We often(经常) bring(带来) ID cards(身份证), work cards(工作证), or driver licenses(驾照) with(与...一起) us to prove(证明) our identity(身份).
11. A) how (怎样， 多么) B) whom(谁)
C) what (什么，...的) D) where(哪里，...的(地方))
If all these cards are forgotten or lost(被遗忘或被丢失), how can we prove(证明) 11 we are?
11. B 空格所在的局部结构充当动词prove的宾语，因此空格处的连接词需要能引导宾语从句， 且连接词在从句中充当表语，指代人， 因此只有B(谁)是答案。
考点：宾语从句。
12. A) oneself(自己， 亲自) B) themselves(他们自己，他们亲自)
C) itself (它本身， 它自己) D) himself(他自己， 他亲自)
In fact(实事上), it's not difficult(困难的) to prove whom you are, because(因为) your body(身体) 12 has identifying(识别的， 鉴别的) markers(标记).
12. C 空格处需要填入的反身代词指代空格前面的名词body， 因此空格处需要填入itself。
考点：反身代词。
Some(一些， 少许的，大约) are physiological(心理的) features(特征), such as(例如) fingerprints(指纹), sounds(声音), facial(面部的) types(类型) and eye color(颜色).
The computer can help to identify you. Suppose(假设，猜想) your features have already been stored(已经被存储) in the database(数据库， 资料库).
13. A) processing(加工，处理) B) copying(复制)
C) coloring(颜色， 给...涂颜色) D) revising(修订，修改)
To identify you, we have to (不得不)take(照相) your picture(照片) with a camera(照相机) and send(送，寄，派遣) it to a computer(计算机) for 13 .
13. A “空13”后面的句子说电脑对输入的人像进行多项处理 (first, then, next, finally)。要表达“处理”这层意思的英语词是 processing。 因此A 是答案。
考点：常见动词的辨析， 上下文之间的逻辑关系(概括+ 分析说明)
14. A) size(大小，尺寸) B) type(类型， 打字)
C) ratio(比率) D) shape(形状， 使成形，塑造)
First(首先), the computer needs to reposition(重新配置) this picture(照片， 图画， 描绘) according to (根据)the position(位置) of your eyes(眼睛), and then(然后， 那么) starts to (开始)read(读取， 阅读) the message(消息) of your physiological (生理学的)features(特征) such as (例如)the 14 of your pupil(瞳孔， 学生) to the whites(眼白， 蛋清， 白色) of your eyes and the shape(形状， 使成形) of his nose(鼻子).
14. C 初看起来 size、type 或 shape都可以与of your pupil(你瞳孔的)搭配使用， 但是空格后出现了介词短语结构 to the whites of your eyes(到你眼睛的眼白)， 由此判断这三个选项出现在空格处都不合适。只有选 ratio, 形成短语结构“ratio of…to…(...与...的比例)”。
考点：短语结构ratio of...to...(...与...的比例)
Next(其次，下一个的), it seeks(寻找，寻求) matching(匹配的) records(记录) from the database.
15. A) recommendation(推荐， 介绍) B) decision(决定， 决心)
C) proposal(建议，提议) D) contribution(贡献， 投稿)
Finally(最后， 终于), it makes a 15 .
15. B 能与空格前面的动词make构成动词短语的选项只有B和D：
make a contribution (to) 捐赠; 作出贡献
make a decision 做出决定
前一句说“计算机从数据库里寻找匹配的记录”， 由此判断B出现在空格中恰当：空格所在的句子说“最终， 它(指代计算机)作出了决定”。
考点：短语结构make a decision
