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 program has already been tested in shops and banks in the USA, Britain and other European countries. 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(确认), 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 have already had machines that can tell who is 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 eye-recognition.

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

The flying car is a symbol of the future. It can be here soon! Companies are racing to make the flying car a real transportation choice. In cities, people get tired of being stuck in a traffic jam. They’ve dreamed about flying machines for many years.

People in Dubai(迪拜) are very lucky, because they can travel in the self-flying air taxi very soon. The egg-shaped air taxi, named the Ehang 184, is made in China. It can travel for up to 30 minutes with a person that weighs up to 100kg. It can reach a top speed of 160 kilometers per hour. What’s more, it only takes two hours to charge(充电) the Ehang 184 fully.

To call for a flying taxi, passengers need to enter their destination(目的地) into a mobile app. The flying taxi then sets the flight plan and takes the passenger to his destination.

Dubai isn’t the first city to show an interest in using the flying car. New York City has started testing the flying car Transition for public use. Transition is a two-seat airplane that runs on gas. It can take off and land at airports. It can also run on roads. Its wings fold up for ground use. They open up for flight. Sounds cool, right?

Thanks to modern technology, we’ll be able to use flying cars in the near future.

Diana loves beaches. But she often sees the sand covered with plastic bottles.

“This needs to be changed.” Diana said. So she studied online. After some tries, she created a new kind of water bottle. People can actually eat it! It can be broken down without polluting the environment. Diana said the bottle felt like a soft candy and tasted a bit sweet.

In the future, Diana will do more tests to make the water bottle stronger and bigger. She wants her water bottles to be used during marathons (马拉松). When runners stop for water, they can get a bottle of water, drink the water and either eat or throw the bottle.
