【题目】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 the number of your credit card 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(眼睛识别)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 eye-recognition 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

【题目】Billy always loved blueberries. They were his favorite fruit. Today he was going to make juice with his uncle. His uncle liked to make juice out of everything. He made carrot juice, apple juice, vegetable juice, and more juices. He had never made blueberry juice before though!

First, Billy and his uncle went to a blueberry farm. They were each given a basket. They picked for an hour and got several pounds. It was hard work picking the little berries from the trees. Now Billy understood why they were expensive in the store.

Next, they had to wash the fruit. Some of them still had leaves. Those had to be pulled off. Then the bad berries had to be thrown away. They washed the berries and made them air-dry.

After that, they pushed the blueberries through a strainer(滤网). The strainer caught most of the seeds and skins, and only left a small glass of dark purple juice to them.

When they tasted the juice, it wasn't very sweet. Billy's uncle didn't want to add white sugar to the juice. It was better to use a naturally sweet juice, like apple juice, pear juice, or grape juice. They used grape juice as a sweetener (味剂), because grapes had a similar color to the blueberries.

【题目】

Ballet is a type of dance. It is a kind of art that can express a feeling, tell a story, or interpret(翻译) a song. The first ballet began in the 15th century. Ballet dancers may be men and women --- ballet is not just for girls! They are strong, pretty, and flexible (柔韧的).

Many movements in ballet are unusual for the human body. Dancers turn their legs out, instead of having their knees and feet straight forward. They also point their feet and may even dance on the tips of their toes.

Dancers must go through a lot of training. Many take classes almost daily if they'd like to be professional (职业的) ballet dancers. They need to practice often to keep up their strength. That also means that dancers need to take very good care of their bodies, so their bodies can keep up with the dancing! Dancers need to be well rested and eat healthy meals. They also should drink plenty of water and listen to their bodies by resting if that's what their bodies need.

In ballet class, most teachers ask dancers to warm up their bodies at first. After that, dancers come to the center to practice other movements. They should start slowly when learning new steps, so their bodies have time to get used to the steps and not get injured.

In fact, it is not easy to become good ballet dancers. Not only do dancers need to control their bodies well, but they need to have a good understanding of music.

Ballet looks soft, but it is really an athletic activity. If you love to move your body and use it to tell stories, ballet might be a great activity for you to try!

1When did the first ballet begin?

2Why do professional ballet dancers need to practice often?
