完形填空When a person walks, the movement of his head, trunk, hipbones and limbs are all reflected in changes in his body. A puter1these changes into a database. Later, the puters can2identify him according to these changes. This is a new biological identification method and it can quickly identify an examinee3disturbing him. It's especially suitable for use in airports and supermarkets. Everybody's voice is4. 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 puters5his sound? First, his voice is recorded, which allows the puters to bee familiar with his voice. It will then turn his sound characteristics into a6of digits. These digits represent the frequency, pitch and rhythm of the person’s voice. These are the7on which the puters can distinguish1 his voice from8. When that person needs to be identified, after he says only one word or two, the puters can identify him. The puters can even identify sounds ing9the wires. This will provide a10guarantee 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 prove11we are? In fact, it's not difficult to prove whom you are, because your body12has identifying markers. Some are physiological features, such as fingerprints, sounds, facial types and eye color. The puter 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 puter for13. First, the puter needs to reposition this picture according to the position of your eyes4, and then starts to read themessage of your physiological features such as the14of your pupil5 to the whites of your eyes6 and the shape of his nose. Next, it seeks matching records from the database.

BDACC ADBDD BCAC解析1.从上下文的意思判断，作者说的是往资料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.check（检查）、revise （修正）和 modify（修改）与上下文的意思都配不上。2.选项 A 的 nearly （不完全地）、选项 B 的 approximately （近似地）、选项C的 roughly （概略地）都不可能与电脑的快速、准确的性能联系起来，而且约摸地辨认也不会有实用价值。只有选 D （accurately 准确地）才符合逻辑。3.前面句子说这是一项新的生物学的辨认技术，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。能辨认人而又不去打搅（without disturbing）被辨认人的技术才是好技术。选项 A 是本题的
