Not long ago, the only time you could see a robot was when you were reading a novel or watching a movie such as Star Wars (星球大戰) . Today, however, a lot of things in science stories have been science facts. Robots are starting to appear in our everyday lives. These robots have different sizes, shapes, and colors. But they all have the same type of man-made “brain”. Leading the robot revolution (革命)are industrial(企業) robots that work in factories. Industrial(工業) robots can do different kinds of jobs that are often boring and sometimes dangerous. Robots are also coming to American homes, though not as quickly as they are entering factories. These robots aren’t as friendly and bright as those you saw in  Star Wars. But, their makers say, today’s home robots “walk”, sense objects(感知物體) in their way (and sometimes knock into them), and even carry objects (which they sometimes drop). Well, nobody is perfect.
We may laugh at home robot today, but some day they may see and hear better than humans do. We humans can only see certain wavelengths(波長) of light, and hear certain sounds. That’s because the abilities of our eyes and ears are limited. Robots, however, need not have the same limits as we have. Robot may also be equipped with devices that pick up information humans can’t. To understand what their sensing devices(傳感器) pick up is a hard job. Remember, man—made brains handle(處理)information, including all kinds of data, as zeroes and ones. Imagine the difficulty in trying to explain to a robot what a football looks like—using only zeroes and ones.

A.help to improve other types of robots

A.They do not have so many limits as humans do.

C.They may be equipped with a special kind of sensing device.
D.They handle information by using zeroes and ones.

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(眼睛識別) 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(依靠) 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 computure will be looking at you in the eye. So smile!
小題1: How does the eye-recognition programme work?
A.You write your number.B.You show your ID card.
C.You look at the machine.D.You say your name.
小題2: Why can the programme be up to 94% correct?
A.Because eyes never change.

The Bermuda Triangle(百慕大三角)is in the Atlantic Ocean, near Florida in the USA. During the past 60 years, more than 1,000 seamen in ships and pilots in planes have lost their lives. It is known as “The Triangle of Death”for its strange seawater and sudden storms. What’s the strangest is the light of the seawater, which looks so bright that it can be seen even from an outer spaceship.
  At 2:00p.m. on Dec. 5, 1945, five planes took off in fine weather from the airport of Florida, on a training task. Two hours later, the leader in the sky radioed that he was “completely lost”. Then there was silence. Another plane was sent to look for them and also disappeared.
  One of the largest ship that had disappeared in the triangle was an American coal ship, 500meters long. The weather was good, and there were no messages for help before it was “gone”. No broken ships or dead bodies have been found so far.

Passage 1  Mobile Phone Madness
How much do you love your mobile phone? A Chinese student had to call 110 for help this week after he got his arm stuck in a toilet trying to rescue(援救) his mobile phone. After dropping his phone in the toilet, he decided to wrap(包,裹) his arm in newspaper in the hopes of keeping clean. But the newspapers became larger in size in the water, and then even his roommates couldn’t help him pull his arm out. So policemen were called and they spent an hour unsticking the stuck student.
Passage 2  Crazy Pet Lovers
How much do you love your pets? Many people in China are famous for how much they love their pets. They dress them up in fashionable clothing and buy them high quality food. But would they spend 7,000 English pounds (68,000 yuan) on a wedding(婚禮) for their pets? And that’s what a couple in Brazil spent on a fancy wedding for their pet Yorkshire terriers( a kind of dog).
Passage 3  Oh, rats!
When something goes wrong, you can often hear Westerners cry “Oh, rats”. But when it comes to Southern China, “Oh, rats!” can mean it’s what you want for dinner.

Have you been asked for money by some disabled beggars (乞丐) while you’re enjoying shopping? Do you have any pity on them who are so poor and lonely or do you just feel afraid of their terrible shapes? As one of the most special groups, disabled people’s living conditions — not only their material (物質的) conditions, but their mental (精神的) world — really need improvement.

If you can be a volunteer and do some work for the disabled people, that would be very nice.
