【題目】B

Mark began to introduce the guest speaker to the listeners, but then stopped for a while. He had forgotten her name.

Barbara hid her valuable things when she went on vacation. When she came back, she couldn’t remember where she’d put them.

Perhaps you’ve had such experiences like these. Most people have. But most of them haven’t realized that they have a memory problem. Neither do they know a simple but important fact: Memory can be improved. If you’ll just accept that, the following will show you how.

First, relax. If you are over worried about remembering something, you’ll forget it. If you keep telling yourself that your memory is bad, your mind will come to believe it and you won’t remember things. When you forget something, don’t follow up with sayings like ＂Oh, my God! I always forget things!＂ Such words will have a bad result on you and your memory.

But relaxing isn’t enough. To improve your memory, you’ll need to take an active role. Like your body, your memory can be made strong through exercise. Look for opportunities to exercise your memory. For example, if you’re learning a language, try to actively remember a lot of new words.

If you don’t take notice of things actively, you won’t remember them. So, you can make pictures of what you see in your mind every day. For example, don’t just put your keys down! If you want to find them again, make a mind picture of the place where you’re putting them.

【題目】B

Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone’s eyes are different. So in the future you won’t have to remember a number when you want to use a machine or take money out of a bank. You’ll just have to look at the machine and it will be able to tell who you are.

The eye-recognition(眼睛識別)program has already been tested in shops and banks in the USA, Britain, Spain, Italy and Turkey. Soon this technology will take the place of all other ways of finding out who people are.

Eye-recognition is a course of recognizing iris(虹膜), which includes the following steps. First, a kind of machine needs to collect different examples of one’s iris from his eyes and store them. Second, when this person goes to the bank to take out money, this machine will have iris feature extraction(采集). Then, this machine will compare the examples kept in it with iris feature extraction. Once the examples and the feature extraction are the same, this person will be identified, and he will take out the money from the bank successfully.

However, scientists are also working on other systems. Machines will soon be able to know you from the shape of your face or hand or even your smell! We already have machines that can tell who you are from your voice or the mark made by your finger.

Eye-recognition is better than other kinds because your eyes don’t change as you get older, and don’t get dirty like hands or fingers, and even twins have different eyes. So the eyerecognition program can be up to 94% correct, depending on how good the technology is. However, some other programs may only be 51% correct now. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eyerecognition.

In the future your computer will be looking at you in the eye. So smile!

【1】How does the eyerecognition program work?

A. You type in your number. B. You say your name.

C. You look at the machine. D. You show your ID card.

【2】Which recognition program has been already in use?

A. Remembering smells. B. Remembering fingerprints.

C. Remembering the shape of faces. D. Remembering eyes.

【3】Which of the following is TRUE according to the passage?

A. The eye-recognition program can be up to 51% correct.

B. In Britain, 91% of people said that they liked the idea of eyerecognition.

C. Everyone’s eyes are different, and even twins have different eyes.

D. The eye-recognition program is widely used now.

【4】 What’s the passage mainly about?

A. You won’t have to remember a number when you take money out of a bank.

B. We already have machines that can tell who you are from your voice.

C. Tell people how the eye-recognition program works and what advantages it has.
