Soon computers and other machines will be able to remember you by looking at your eyes! The programme 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 programme is already being 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.

    However, scientists are 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, or get dirty like hands or fingers. And even twins have different eyes, so the programme can be up to 94％ correct, depending on how good the technology is. Some programmes may only be right  51％ of the time. 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 you in the eye. So smile!

Every year landslides cause 25 to 50 deaths and $2 billion in damage in the United States. And in December, a single event killed more than 2000 people in the Philippines. Sending workers to stabilize mountainsides using steel bars can help a lot, but it introduces new difficulties because of dust and loosen heavy, dangerous debris from the work. “It’s a quite dangerous job,” says Giorgio Pezzuto of D’ Appolonia, working with eight other companies. Now there may be an answer: a three-ton robot called Roboclimber.

“The idea is to operate a machine far away that can do the stabilizing job without a human being near,”says Pezzuto, manager for the project, which is supported by a European organization. Engineers say that the machine will be faster and cheaper than manual labor. The robot, a large radio-controlled four-legged spider, has cost at least $2 million so far. It should be able to climb mountainsides, drill holes and insert steel bars there. Testing should begin in May.

1.The underlined word “event” refers to_____

A. earthquake               B. debris             C. dust        D. landslide

A. to tell people how serious the damage caused by landslides is

C. to show people how to use a new robot

D. to introduce a new robot that can be used to stabilize mountainsides

3.What does the robot look like?

A. human being         B. spider            C. steel bar        D. a drill

4.A landslides cause _____________in damage in the United States Every year .

A. 25 to 50 deaths       B. more than 2000 people died

C. $2 billion           D. both A and C

5.The biggest advantage of this product is that____

A. it will be faster and cheaper than manual labor

B. it can climb mountainsides, drill holes and insert steel bars there.

C. it can do the stabilizing job without human beings near
